The moment the "Bloss Flower" drove out of the Bloss Island military base, Li Yis was sitting in Pang Xiaonan's cabin. He looked at the scenery outside the window and asked Pang Xiaonan: "How is your mood? You will face the Bloss Disc soon."

"Nothing," Pang Xiaonan lay on the bed with his head in his hands, "I'm looking forward to it."

"I'm a little nervous. This is the first time I've grown up to an unknown area." Li Yis did not hide his mood at this moment. As a great disciple of the Dongyue Sect, he has been to many places in the world, and he has been to increase his knowledge, but he has never set foot in such a dangerous place as the Bloss disc.

"It's not too nervous yet," Pang Xiaonan sat up and patted Li Yis on the shoulder. "When you find that the electronic devices have failed, it's not too late to be nervous."

"The Bros Disc is not just making the electronic device fail as described, right?" Li Yis looked at Pang Xiaonan with a relaxed expression.

"Of course not only, there may be storms, unknown beasts in the sea, wait." Pang Xiaonan pointed to the sea outside the window, "Maybe we may encounter the legendary dragons, not necessarily."

"Ha, that's a big fortune." Li Yis followed Pang Xiaonan's gesture and looked at the sea.

In the cab, the instrument showed that the "Bloss Flower" was getting closer and closer to the Bloss disc. Booktonlin's expression became more and more serious. He said to the mechanic who drove the ship: "How long will it take to reach the edge of the Bloss disc?"

"It's about 10 minutes." The mechanic's eyes were staring at the sea in front of him without blinking, and the originally calm sea began to surging.

Booktonlin's expression was also stunned for a moment, then he left the cab and walked towards the cabin.

"Everyone, gather!" Booktonlin stood at the entrance of the cabin and shouted into it. He called everyone in the cabin to the deck.

Everyone felt the bumps on the sea in their respective cabins in advance. When Booktonlin called out, his originally nervous hearts became even more up and down, and quickly gathered on the deck. Everyone knew that they were facing real danger.

Booktonlin pointed at the surging sea surface. At this time, the "Bloss Flower" had already begun to shake greatly. "We are about to arrive at the Bross Disc. Before we arrive, I want to assign a task to everyone!"

The waves on the sea were getting bigger and bigger, beating the hull of "Bloss Flower" and making a huge noise. Booktonlin had to increase the volume and almost shouted and talked to everyone.

"All Black Mamba members, go back to get the equipment and come back on the deck, and be ready for battle!" Booktonlin looked at the members of the Black Mamba Guard with a serious expression, and then looked at the scientific expedition members with horror in their eyes. "Scientists of the scientific expedition team, please go down to the cabin and gather in the restaurant. Without my order, you are not allowed to leave the cabin."

Booktonlin looked at Pang Xiaonan again, "Pang Xiaonan and Li Yis stay in the cabin to protect the scientific expedition team. Without my order, you are not allowed to leave the cabin and go to the deck without authorization!"

"Do you all understand?" Booktonlin shouted loudly, the sound of the waves slapping the hull was getting louder and louder, almost drowning his voice, and the hull was shaking more and more violently, and everyone's hearts were in their throats.

"I understand!" The Black Mamba Guards and the members of the scientific expedition team replied in unison. The huge response sound made them feel a sense of passion echo in their hearts. This is the power of the team, which makes them feel a little relieved.

"implement!"

With the order from Booktonlin, each team member began to perform his own tasks. Pang Xiaonan and Li Yis protected the seven scientists to get out of the cabin.

The living area of ​​this landing ship is very simple. Apart from the cabin where everyone sleeps, there is only a large restaurant left. At this moment, all scientists gathered here. With Bridgemorgen and his assistant, everyone's expressions were a little terrified because the hull was shaking more and more violently.

Pang Xiaonan sat next to Professor Li Sanming, and then directed Li Yis to sit on the other side of the restaurant. The two of them blocked the two ends of the restaurant, forming a junction with each other.

Professor Li Sanming's face was different from others. He looked at the surging waves outside the round window without a trace of panic.

"Professor Li Sanming, are you okay?" Pang Xiaonan thought Professor Li Sanming was frightened. He knew that Li Sanming had a heart disease, fearing that something unexpected happened before he reached the Bloss disc.

"It's okay," Professor Li Sanming turned his head and looked at Pang Xiaonan with a smile. "This little bit of wind and waves is nothing. I remember when I was working in the wild, I encountered more terrifying beasts than this one."

As an outstanding geologist, Professor Li Sanming works in the wild all year round, so he encounters more accidents and thrills than ordinary people have ever walked.

Pang Xiaonan asked with a smile: "Professor, can you tell me the story of the Bloss disc? I only heard that it is very strange here. Do you know what exactly caused it?"

Pang Xiaonan wanted to attract Professor Li Sanming's attention. Perhaps telling stories will make Professor Li Sanming no longer immersed in the storm.

Professor Li Sanming smashed his mouth and began to tell Pang Xiaonan about the mysterious conjectures about the Bloss disc. He was originally a famous professor in the university, and his favorite was to pass on what he learned throughout his life to his disciples.

"So far, the explanations of the Bloss disc can be summarized into the following categories. The first category of views, which are caused by supernatural reasons, and are related to whether it is the alien flying saucer. The second category of views believes that this is caused by natural causes, such as geomagnetic abnormalities, hollows on the ocean floor, and even people have proposed bubble theory, clear sky turbulence theory, water bridge theory, black hole theory, etc., using some strange natural phenomena to explain the Bloss disc."

Professor Li Sanming fell into memories, and his assistant handed over a thermos cup, "Professor, it's time to take medicine." Professor Li Sanming took a small red pill, unscrewed the lid of the thermos cup, threw the pill into his mouth, then picked up the thermos cup and took a sip of water, swallowed the pill into his stomach.

"The vortex theory is a relatively broad conjecture. Some scientists believe that the reason why ships suddenly disappear when they pass through the Bolus Disc Sea may be because there is a magical vortex in this sea area. The Bolus Disc Sea is the location of the amazing and famous Sargasso Sea. In terms of hydrodynamics, Sargasso Sea is a place where thermal energy accumulates. The sea currents around this sea are complex, and its boundary is not land, but are composed of a counterclockwise circulation combined with several currents in the East. A scholar who studies vortexes in the country of Amarica believes that the direction of the vortex rotation is Harley Road.

The rotation of the sub-star is related. The direction of the vortex in the northern hemisphere is counterclockwise. The warm currents merge in the Bolus disc sea area to form a huge current, which is an extremely unfavorable factor for ship navigation. It is said that a 25-meter wave can fold large ships into two pieces and swallow unexpected ships. However, meteorologists in some countries refute that such a demon-like wave will not occur, and it is even more impossible to hit a large ship of thousands or even tens of thousands of tons to the bottom of the sea without leaving any trace. Unless something mysterious and powerful drags them to the bottom of the sea."

Professor Li Sanming paused, picked up the thermos and took a sip of water. At this time, a big wave hit the window and the hull swayed violently. Professor Li Sanming couldn't sit firmly and fell towards Pang Xiaonan. Pang Xiaonan quickly held his body with one hand and held his hand holding the thermos with the other to prevent the warm water from spilling out in the cup.

"Thank you." Professor Li Sanming sat down and continued to give lectures with Pang Xiaonan.

"Some scholars believe that there may be two or more reverse flows in the sea area of ​​the Bloss disc, forming a phenomenon of different interface water quality density. This is the so-called inner wave. During the tidal reflux, the sea water produces vortex shock, which is manifested as a large-scale vertical whirlwind. Some scholars believe that under the influence of strong north winds and surging waves in the depths of the ocean, sometimes internal waterfalls may occur up to thousands of meters and gradually descending huge water flows. This inner waterfall is almost invisible on the sea surface. Therefore, people cannot see this inner waterfall from the outside of the ocean. However, under certain conditions, the mass is huge.

The liquid will reach an extremely high speed when it descends, and sometimes it can rotate at 0.5 meters per second, which will form a huge whirlpool with a diameter of kilometers and a depth of 500 meters. This whirlpool can make giant ships bury at the bottom of the sea. Secondly, the island of Bloss is often hit by terrible hurricanes, which are hit from the direction of the Bloss disc sea area. Hurricanes cause huge waves and often form water walls more than ten meters high. Sometimes they can encounter sea tornados, and even absorb sea water to a height of hundreds of meters or thousands of meters. If ships and planes sailing in the Bloss disc sea area encounter these terrible strange phenomena, they will not be able to escape the fate of being crushed to pieces."

Professor Li Sanming looked at Pang Xiaonan with a hint of worry in his eyes, but soon he calmed down again and continued to tell.

"A foreign scholar who studies vortex believes that a mesoscale vortex is equivalent to a concave mirror. When the sunlight shines on the vortex, that is, this concave mirror, the focus of the light can generate a very high temperature. He conducted an experiment and incident a strong light at an incident angle of ° into the simulated vortex, which resulted in the focus of the vortex igniting a thin piece of paper. Based on the results of this experiment, he asserted that there are many huge vortexes in the Bloss disc sea area, which are many huge "concaves"

". When the incident angle of sunlight is °, it is illuminated in a vortex with a diameter of 1 km. The diameter of the focus of the concentration is about one meter, and the temperature can reach tens of thousands of degrees. Such a high temperature is enough to make the aircraft and ship melt or explode in an instant. The larger the diameter of the vortex, the higher the temperature of its focus of the concentration. At night, without sunlight, although the vortex cannot concentrate, the rotation speed of the huge vortex is extremely fast, which will inevitably cause electromagnetic field disturbance, which will cause abnormal magnetic compass and other navigation instruments, causing the aircraft,

The ship was out of control and buried at the bottom of the sea. Thirty years ago, a team of scientists from Amarica, United Kingdom and Rush, investigating the mystery of the Bloss Disc, used artificial satellites operating in space for reconnaissance. According to laser scanning photos, there was a huge turbulent vortex in this triangle. Dr. Kels, the chief scientist who led the investigation team, said that the giant vortex appeared for only 3 seconds, but its power was infinite. Its appeal was so strong that it was better than Hallelujah Star.

Any hurricane, earthquake or volcanic eruption is much more powerful, and it is no less powerful than the gravitational force that affects Hallelujah tides. It can affect the weather at night. When this huge vortex appears, it is erratic and difficult to detect. It is like looking for a needle in a haystack. When a sudden huge vortex appears, it is invincible. Ships on the sea and planes in the sky will be swept into the seabed, causing planes and ships to disappear. This discovery provides a realistic basis for the vortex theory."

Pang Xiaonan listened with relish, but the hull was shaking more and more violently. He had to look at Professor Li Sanming with concern and interrupted his speech: "Professor, are you in good health? Do you want to take a break?"

Professor Li Sanming waved his hand and said, "I'm fine, let's continue talking."

"There is another theory of the sea cave theory. Some scholars believe that in ancient times, during the drift of the mainland, some pits or holes formed on the seabed crust in the Bolos disk area. In modern times, the crust movement here is still frequent, and earthquakes often occur in the Dabudian Les Island east of the Bolos Island. When an earthquake occurs, the top of this hole may collapse and be concave, just like a large mouth open on the seabed. The sea water will surge into and open rapidly.

If the ship encounters this situation sometimes, it will be swallowed up. Therefore, there will be no fragments, oil stains, crew members' bodies and any other traces left on the sea surface, and nothing can escape the misfortune of being dragged into the abyss under the sea. However, many scholars are skeptical of the above speculation. Because there is no definite evidence that the crust of the Bloss disc sea area has undergone a violent activity that can open the large mouth or be enough to engulf the sea surface ship."

"Then is this just a guess?" Pang Xiaonan likes this metaphor of opening his mouth wide. In this way, it is actually a creature under the sea.

"Not necessarily," Professor Li Sanming shook his head, "It may be true, because there is no data to show that there has been no intense activity in the seabed of the Bros Disk."

"There is another theory called Water Bridge. Some scholars have put forward a unique and novel view. Although the Bros Disc Sea Area is far away from the East Ocean Sangbusi Island, there is a water bridge between the two. This view began with an accidental discovery. Once, a friend from the East Ocean Sangbusi Island told our scholar Brown Aronson about a strange news that some broken ship fragments of unknown origin were sometimes seen along the coast of Sangbusi Island. All the residents on the island were very surprised that there was no shipwreck in the local waters. Why did these broken ship fragments suddenly surge out of the sea water? Where did they come from? Residents all felt mysterious. Aronson was ignorant of the fact that there was no shipwreck in the local waters.

This strange news is very important. After repeated investigation and verification, it was proved that the broken ship fragments suddenly floated up from the coast of Sangbusi Island, which was the remains of the ship that had mysteriously disappeared in the Blos Disk Sea Area. Aronson enthusiastically conducted a systematic study on the mystery of the Blos Disk Sea, collected a large amount of information extensively, and conducted a detailed investigation of the seabed geological structure and complex hydrological meteorological conditions between the Bloss Islands and Sangbusi Island, thus proposing a unique and novel insight. There is indeed a natural underwater bridge between the Bloss Disk Sea Area and the East-Da Dongyang Sangbusi Island. The magnetic field strength of the water bridge is extremely high, very different from its adjacent sea surface, and it is fickle, so that it has

It was a powerful attraction. If the ship encounters this strange attraction by chance, the navigation compass and other instruments on the ship will fail, resulting in the ship's crash and sinking. The underwater bridge is like an oil pipeline. The wreck flows from one end to the other along the "water bridge", that is, from the Bros Disc Sea Area to the Sanbusi Island Sea Area in the East Pacific. Aronson reported his unique insight to the Institute of Geology of Fort Sandalee in China. Professor Jonathan Smith of the institute affirmed the great value and reliability of this discovery, believing that Aronson's unique insights provide a new theoretical basis and a credible way for further in-depth exploration of the mystery of the Bros Disc Sea Area in the future. Aronson's new

The strange discoveries and unique insights have caused a sensation around the world and attracted widespread attention and discussion among scientists from all over the world. In order to prove that there is indeed a long underwater "water bridge" between the Bloss Disc Sea Area and the East-Da Dongyang Sanbusi Island Sea Area, Aronson conducted an experiment. He first accurately measured the Earth's magnetic field, and then conducted an experiment on tracking the magnetic field in a small pool. Thirty years ago, he used an electronic computer and 50,000 liters of bright red water to perform his experiments to geologists from all over the world. However, many scholars are skeptical and negative about Aronson's novel discoveries and unique insights. He even believes that the above hypotheses are myths that cannot be realized at all."

"This is indeed a bit nonsense." Pang Xiaonan smiled and said, although he was not very good at scientific principles, the myth of Water Bridge seemed to be a little bit nonsense.

"All conjectures are possible until there is no definite evidence." Professor Li Sanming is a scientist and has always had a rigorous attitude towards science. He will not be sure of any theory, nor will he deny a certain theory.

"There is another theory that infrasound theory. Some scientists believe that the "devil" in the Bloss disk area is a strong infrasound wave, which has great destructive power, which is the main cause of the destruction of aircraft and ships and death of crew members. As early as 100 years ago, the geophysicist of the Rush country, Bobosulekin discovered the infrasound waves produced by sea waves. Later, many scientists also discovered that volcanic eruptions, earthquakes, lasers, thunders, aircraft flights, storms, etc. can also produce infrasound waves. In areas where storms are brewing, before the storm is about to come,

Infrasound oscillation is emitted. This oscillation is generated when the air flow is hit by wave peaks. They propagate in the air at a speed of up to 330 meters/sec, while in water it travels faster, reaching 1,650 meters/sec. Infrasound is a sound that the human ear cannot hear, but their destructive power is amazing. When the oscillation frequency of the infrasound wave is about 6 Hz, it can cause fatigue, and then develop from anxiety to instinctive fear. When the frequency is 7 Hz, it can cause the heart and nervous system to become paralyzed. Strong infrasound

The waves can cause people to go from pain to death, break the hull and disintegrate the plane. 40 years ago, an Amarica aircraft flew over the edge of the Bloss disk and disappeared from the fluorescent screen for 10 minutes. After the plane landed, all the clocks on board were slower than on the ground. 30 years ago, an explorer and his four partners entered the Bloss disk by a seaplane and stayed there for several days. One night, during dinner, they discovered a strange phenomenon that the fork they used to eat suddenly bent, and at the same time the water was

The dozen keys on the plane were deformed, and even the pointer on the compass was deviated from 40°. Some scholars speculated that the above strange phenomenon may be due to a weak or moderate infrasonic oscillation. Some scholars disagree with the above view. They believe that only high-intensity infrasonic waves can affect animals and human organs, but that is the phenomenon observed in experiments conducted in a closed cavity. It is difficult to generate high-intensity infrasonic waves in nature. Some scientists also imagine making infrasonic weapons, but it is just a concept."

Pang Xiaonan's eyes lit up, "You mean, an explorer has entered the Bros disc and is still alive?"

Professor Li Sanming refused to comment, "Are you talking about that explorer? This is just that he has been to the Bloss Disc himself, but he has no evidence to prove that he has been there. Maybe he just walked around the edge of the Bloss Disc."

Through the glass window, Professor Li Sanming pointed to the surging waves outside the cabin and said, "Do you think his seaplane can withstand such a big storm?"

"It's very difficult." Pang Xiaonan was disappointed. It seemed that no one could enter the Bloss Disc alive and come out alive, but he was not discouraged. Maybe they would break the curse. Also, the explorer had no definite evidence, as it seemed that he had never been to the Bloss Disc alive.

"There is another theory of black holes. The theory of black holes is that some celestial bodies with strong attraction have fallen in the sea area of ​​the Blos disc. They have become objects with small bodies but extremely dense. Any matter, including light, will be sucked in as long as it is next to it. But it does not release any matter, so people cannot find it. It is like a black hole, and ships and planes are affected by it and are sucked into the sea before they can ask for help. This view was proposed by Amarica scholar Weiler. He believes that in Blos

There is a meteorite that fell 1,500 years ago in the disc sea area. This high-density meteorite has made the Blos disc area a huge black hole. Once ships and planes approach, they will be sucked into it and can never be escaped. Moreover, a meteorite has fallen from Belize on the Borde Peninsula, not far from the island of Bloss. This meteorite has destroyed all living things on Hallelujah, and its dust has spread over Hallelujah for ten years. It is unknown whether the Blos disc has also been affected by it."

"Don't black holes exist in outer space?" Although Pang Xiaonan's knowledge reserves are not rich, he still has a little knowledge of basic physics.

"The black hole mentioned here is just a metaphor, which means that it can swallow everything." Professor Li Sanming patiently explained to Pang Xiaonan.

"There is another theory of combustible ice. Combustible ice, also known as natural gas hydrate, is a solid substance composed of water and methane mixed under high pressure and low temperature conditions. It looks very similar to ice and snow or solid alcohol and can burn when exposed to fire. Professor Kreiner of the United Kingdom of Austria and the United States, and Professor Kreiner of the University of Leeds proposed a new view. He believed that the culprit of shipwrecks or plane crashes in the Bros Disc waters is the huge biogas bubbles produced by combustible ice under the sea. When a violent earthquake occurs on the seabed, the blocky combustible ice crystals buried underground are turned out. Since the main component of combustible ice is methane, it will vaporize rapidly due to external pressure. A large number of bubbles rise to the water surface, reducing the density of the sea water and losing the original buoyancy.

At this time, the ship passing here will sink to the bottom of the sea like a stone. If an airplane passes by at this time, when methane gas encounters a scorching aircraft engine, it will immediately burn and explode. A laboratory in Amarica once conducted a simulation experiment, blowing a large amount of air upward from the bottom of a small swimming pool, and the bubbles formed fill the pool, allowing a swimmer with good water to jump into the pool. At this time, his body will sink straight down like a weight, because the water filled with air has lost its buoyancy. This shows why many ships suddenly sank to the bottom of the sea in the Bermuda Triangle and disappear. So far, this speculation is the most convincing scientific statement, and scientists have found samples of combustible ice in the Bolos Disc Sea."

Do you also agree with this theory?" Pang Xiaonan was very curious about the burning sea water. If it really exists, the Bloss Disc would be a huge hot spring.

"Only when I really see this phenomenon, I will agree with this theory. Otherwise, no matter how convincing this speculation is, it is just a speculation after all."

Professor Li Sanming looked out the window and was very strange. The sea that had just been surging has calmed down now.

Pang Xiaonan had a bad premonition.

Professor Li Sanming was a little relieved and continued to turn his head to explain to Pang Xiaonan.

"The following theories are also very popular. One is the high-pressure oil and gas theory. This statement was proposed by Donald Davidson of the United Kingdom of O'Netherlands. He believes that the seabed of the Bloss disc sea area is rich in natural gas. Due to the influence of changes in the external environment, the natural gas in this sea area is released in large quantities, which greatly reduces the oxygen content of the air here, thus extinguishing the aircraft's engine due to lack of oxygen. The scorching exhaust gas discharged from the tail exhaust pipe ignited the sea again.

The area constantly gushed out of natural gas, which burned the falling plane completely. Another is the theory of clear sky turbulence. Some scholars believe that in the clear sky, sometimes there will be surging undercurrents hidden under the calm sea, and occasionally there will be strong disturbances, causing the plane to bump violently. Aviation meteorological experts say that this airflow that comes without a trace is clear sky turbulence. It is called the "invisible killer" of the aircraft. When a sailing plane encounters it, it will bump violently, and sometimes it will

Infrasound produces, tearing the plane to pieces. Some people believe that the mystery of the disappearance of aircraft in Bermuda is because of the turbulence of clear sky. However, this theory can only support the phenomenon of aircraft disappearance. Another is the theory of natural lasers. Some scientists have proposed the hypothesis of natural lasers. They believe that the sun, the upper layer of the atmosphere, the air flow, and the ocean surface will form all the components of the laser generator on its own. The sun is the source of wave generation, the upper layer of the atmosphere and the calm ocean surface are emitters of light waves, moving

The moving air flow is a special active medium. Under certain conditions, sometimes they will form a very strong natural laser on their own. If an aircraft and ship encounter this natural laser by chance, it will immediately vaporize on the spot and turn into vanish without leaving any trace. Therefore, any oil stains, debris or corpses of the dead aircraft ship will not be found at all and disappear without a trace. But this is just a hypothesis and speculation of a few scientists, and there is still a lack of solid and powerful evidence."

"Professor, your memory is really good." Pang Xiaonan gave Professor Li Sanming a thumbs up. An old man in his 70s didn't have to read books and told so many theories and stories, which surprised Pang Xiaonan, a young man.

"It's not that I have a good memory. I just did a lot of homework before coming to Bloss. After all, our scientific expedition task this time is very arduous. It is necessary to learn more about the history and situation of Bloss disc." Professor Li Sanming gathered up a few messy hairs on his head. "I look through the information on Bloss disc every day when I have nothing to do, and I am familiar with many things."

In the cockpit, Booktonling asked the first mate who held the steering wheel tightly and said, "Did we get to the Bros Disc?"

The first mate turned his head and looked at Booktonlin nervously, "I think it must be here, our instrument failed."

Booktonlin looked at the dashboard, and sure enough, all the instrument pointers dropped to the 0 scale.

"What should we do? How do we judge the direction of the ship's travel?" Booktonlin's expression became serious. Without the instrument on the ship, it was like a headless fly. He could only wander around the Bross disc. Whether he could go out depends on luck.

"Captain, I'm ready." The first mate took out a watch, which was a fully automatic mechanical watch.

"Can this watch determine the direction?" Booktonlin looked at the dial in confusion, with no pointer indicating the direction.

"Use this watch and the sun to determine the direction." The first mate pointed to the sky. Now the wind was calm and the waves could be seen hanging in the sky.

"Oh? Is there such a thing?" Booktonlin originally thought that the first lieutenant would take out a compass, but he quickly denied the idea. Even the power facilities were invalid. The compass would probably be disturbed by the chaotic magnetic field here.

"The sunrise position in winter is southeast, and the sunset position in southwest; the sunrise position in summer is northeast, and the sunset position in northwest; the sunrise position in spring, around autumn equinox, eastward, and westward. As long as there is a sun, you can use the watch to distinguish the direction. Read the time at that time according to the 24-hour schedule, divide the hours by two, and you will get an hour. Put the watch horizontally on your hand or on the ground, and aim this moment of the watch at the direction where the sun is. At this time, the direction pointed at 12 o'clock on the surface of the watch is north, and the direction pointed at 6 o'clock is south." The first mate placed the watch on the bridge for a while, adjusting the angle with the sun.

"What if there was no sun?" Booktonlin didn't dare to have hope for the sun seen in the Bloss disc, because the bad weather was likely to continue. They had just felt this kind of changeable weather in the edge of the Bloss disc.

"Without the sun and the stars, we can't always withstand the bad weather, the storm sometimes ends." A relaxed smile appeared on the first mate's face. He was an experienced sailor, otherwise he would not have been sent by Hei Mamba to serve as the captain and mechanic for the operation. He has more than 300,000 nautical miles of experience in maritime navigation.

"We can distinguish the directions of the North Star and the Southern Cross. Taking the North Star as an example, we first look for the spoon-shaped North Dipper and extend the interval between the two stars on the spoon C by 5 times, and then we can find the North Star on this straight line. The direction of the North Star is the north. At night, you can sometimes see the South Cross Star, which can also be used to distinguish the directions. The South Cross Star is composed of four brighter stars, which is like a cross. At the bottom right of the Southern Cross Star, extending downward along the line between the two stars A and B is about four and a half times the two stars, which is the south."
