Luo Yuan stood on the branch and looked up at the sky, losing his mind for a long time.

However, the sky could not see anything except the stars. Everything he saw tonight had a huge impact on his mind, and everything seemed like a dream.

After a while, he came to his senses and walked back to the cave numbly and moved the huge rock away. Wang Shishi was still sleeping softly, snoring all night, but he had no sleepiness on his face. He leaned against Wang Shishi and sat blankly on the bear skin.

He felt that he needed to be quiet.

What is the purpose of extraterrestrial civilizations coming to the earth?

Is it a simple scientific research investigation, or a preparation for conquering the earth, a strange visitor or a pure enemy, and even the crazy mutations of animals and plants over the past few years, and nothing is known about it.

Luo Yuan was not sure whether the reconstruction area or the only remaining civilized forces in mankind have noticed this group of extraterrestrial forces, but the possibility was slim.

This place is more than 600 kilometers away from the reconstruction area. It is completely a sphere of influence of mutant beasts and a forbidden area for human activities. Even high-altitude unmanned reconnaissance planes rarely appear. What's more, the behavior shown by this unknown extraterrestrial civilization seems to be quite cautious. The activity time is late at night, and the chance of discovering is pitiful. If Luo Yuan had not been away from the reconstruction area to find the wisdom tree and happened to pass by here, he might have been at a loss.

As for the spacecraft that may exist in space, it is no simpler to find it in the vast space than to find a specific fine sand in the sea. It can hide behind the moon or be stationed in the planetary belt. With the human technological level, it cannot be found at all.

What's more, the strength shown by this extraterrestrial civilization is far stronger than that of the earth. Just like the radar during World War II, it has no solution to the current stealth aircraft. Even if the spacecraft appears openly in the extraterrestrial atmosphere, it may be difficult to detect.

The reconstruction area is very powerful today. The explosion of technology has made the reconstruction area's strength a thousand miles a day. Although the population is less than one-tenth of that before the end of the world, in terms of conventional military power, it is more than ten times stronger than before the end of the world. However, in fact, the battle between humans and mutant beasts has always been in a stalemate and falls into a certain balance. The mutant beasts cannot make an inch of progress, and humans are also unable to recover their homeland.

The battle is not only on the front line, but also goes deep into the hinterland. This is a war of all-round, including the sky, land, underground, from mutant beasts like mountains to flies, mosquitoes and bacteria that grow in the city. The entire reconstruction area is like an isolated island in the sea, with waves surging outside and rainstorms inside. Once a certain balance is broken, it is like a domino, and it will immediately fall into a crisis of overturning.

However, now there are more extraterrestrial civilizations with unknown friends and enemies...

The more you think about it, the more pessimistic Luo Yuan becomes, and the future of mankind seems to be filled with a shadow.

...

The sky gradually became brighter, and Luo Yuan rubbed his face hard, exhaled a breath of turbid air, and the seventeen-point will made him quickly control his negative emotions. No matter what the future will be, life will continue.

"Brother Luo, you're up." Wang Shishi woke up, sat up and stretched.

"Well, eat something, and after breakfast, we will set off." Luo Yuan said, looking at Wang Shishi's sleepy and ignorant look, ignorant is a blessing, at least you don't have to bear this heavy pressure.

There was still some left for dinner last night. In addition to the barbecue that was hard like a stone, the insect eggs were also ready to eat. The two of them had a simple breakfast and then set off again.

The cool morning is the most comfortable time of the day. At this time, the high temperature has fallen, and the breeze blows on your body. I feel that the whole pores are breathing. Because of the fog last night, the ground seemed a little wet. Walking in the forest, water droplets dripping from time to time.

However, before the water droplets fell, they were suspended in the air by an invisible force. After a day of rest, Wang Shishi was energetic. His fatigue had recovered last night. While rushing along, he still had the energy to control the water droplets and entertain himself.

The air here has gradually brought a salty and wet smell. The sea is not far from here. Half an hour later, you can see concrete remains covered with moss and vines from time to time on the road. However, apart from these, there is no trace of human civilization.

The dead leaf layer, several meters thick on the ground, covered everything. If it weren't for the coordinates that it was already Mushi County, it would be hard to believe that this primeval forest was actually a city with a population of more than 200,000 a few years ago.

Luo Yuan flew into the air, identified it, and continued to walk forward.

Yaozishan is thirty or forty kilometers away from Mushi County, which is very rare. There is no people in a radius of several miles. Before the end of the world, there was no road except a dirt road that could be accessed. Now there is no road, so it can only be distinguished by the naked eye.

On the map, the name Yaozi Mountain is simply not found. It is just an inconspicuous peak in a rolling mountain range. No one except the locals know it.

Compared to before the end of the world, there were basically barren mountains, with sparse plants, and even bare hills. Nowadays, plants with huge sizes and a height of 100 meters are irresistible to greatly increase the difficulty. Look at the continuous mountain nearby, which is mostly a mountain with a drop of only a few hundred meters. It is undoubtedly a whimsical idea to find a hill similar to a waist as the name suggests.

If you want to find it, you can only follow the waterfall to search.

This is not difficult. Luo Yuan's keen ears had already heard the rumbling sound of a waterfall. However, the wanderer said that the migration was half a year ago, when sea level rise had just begun, and it was still in a dry area.

Now, judging from the salty and fishy smell in the air, this place has become a coastal area, with a humid climate and abundant rainfall. In addition, it is a mountainous area, and the terrain gap is extremely large. Waterfalls are no longer rare. There are seven or eight waterfall sounds heard by Guang Guangluoyuan.

Fortunately, it was just a matter of taking some time.

Luo Yuan searched everywhere, and when it was almost noon, he came to the fifth mountain with a waterfall. When he saw it, Luo Yuan's eyes lit up. The mountain top was not high, with a drop of about three or four hundred meters. The strange thing was the shape. The mountainside was slightly sunken. If the plants were removed and the body was slimming, it looked exactly like the "waist mountain" that the wanderer called.

A waterfall tilted down from near the bottom of the mountain and fell down with a bang. It was a waterfall formed by a broken underground river. The waterfall was not abundant and the drop was not high. The nearby waterfall was not eye-catching, so Luo Yuan only found it now.

Luo Yuan left Wang Shishi in place. After all, it was not safe in front of him. He could scare the Huiren tribe into fleeing in a hurry. The migratory tribe was at least level six creatures. The level six creatures were fine. He could handle it easily. The most feared thing was that he could encounter level seven. Such a huge thing, even if it was just a thrust and a jump, could cause large-scale damage. Once he encountered it, even he would only do his best and he could no longer care about Wang Shishi when fighting.

He carried the saber to light the road. The mountain road here was rugged and extremely steep. Several human-eating vines that seemed like living creatures spread quietly like snakes. They tried to attack, but were cut off by Luo Yuan swung his sword one by one.

Several huge man-eating flowers bloomed in the shade of the trees, colorful and colorful, emitting a sweet fragrance, and were filled with dry bones nearby.

Not far away, a giant plant as high as a hundred meters was moving slowly. With every step, the roots of a tree as thick as a giant python were pulled out of the ground or penetrated into the ground, causing a huge earthquake. The "old" bark covered with cracks on the tree trunks formed into a huge blurred face, and the expression changed slightly as it moved.

The plants here seem to have been mostly animalized, and three trees, which are rare in sight, have been discovered in just a few kilometers of road.

Luo Yuan slapped a bloodthirsty mosquito open, and as he heard the increasingly loud waterfall, his speed suddenly accelerated.

In a few minutes, Luo Yuan jumped gently onto a huge rock, and there was a waterfall ahead.

The terrain here is relatively flat, with the ground covered with oval stones of all sizes. The drop of the waterfall is only ten meters. It falls below the deep pool, and eventually forms a river more than ten meters wide, which winds along this rocky beach and flows into the valley bottom.

What's strange is that the plants here are quite sparse and are much smaller in size. At first glance, there are only a few trees growing on this rocky beach. In addition, there are even fewer vines and weeds with strong vitality.

The strange plant near the Tanshui, which was fifty or sixty meters high, was obviously outstanding under this low "shrub".

The spherical roots, sarcoma-like lumps, sparse leaves, twisted like wrung towel-like trunks, and the fruits as big as babies' heads all indicate their identity.

"Wisdom Tree"

Luo Yuan's eyes lit up and his breathing was a little rapid.

This wisdom tree is much larger and thicker than the one I discovered before, and its color has also changed. The trunk of the tree was yellow and purple, but this one is completely purple, even a little black, as if it was filled with blood.

The level of this wisdom tree is obviously higher than the original one!

But although he was anxious, Luo Yuan did not act rashly. He looked around carefully. There were no creatures nearby, and even the ordinary insects and birds in the forest seemed to have disappeared. This was very abnormal.

I felt carefully that there seemed to be a faint depression remaining in the air, which made Luo Yuan frown slightly.

He hesitated for a while, then pressed the hilt of the knife and moved forward slowly. At the same time, he felt the expansion to the limit and carefully searched for the movements nearby. However, he did not feel anything wrong at all. As he walked step by step, he soon felt that the pool had been covered.

I originally thought that the mutant beast was in the pool, but I didn't find it at all.

The pool is not deep, only three or four meters, and the radius is only a hundred meters. There is no dark hole underneath. There is nothing except a group of "little fish" several meters long wandering in the water.

In the end of the world, creatures of this size can only be called small fish.

Luo Yuan breathed a sigh of relief. It seemed that he was a false alarm. The mutant beast that was originally here might have died or had left this place. In the jungle, the strong are prey on the weak and cruel. Even the most powerful mutant beast would encounter an accident if it was accidentally done.

However, the bones under the Wisdom Tree were a bit strange. They didn't care about it when they looked away. At this time, they felt strange when they were nearby. Luo Yuan found that each of these bones was extremely huge. Even one of the thigh bones lying on the ground was about ten meters long and one meter five meters thick. They were like a huge stone pillar, tilting down on the bones, several circles larger than the soul-devouring beasts that Luo Yuan had seen before. There were many such small bones nearby.

It’s okay to just one or two, but there are all such bones here, which are piled up like mountains near the Wisdom Tree. The entire sea of ​​bones is as thick as forty or fifty meters, accounting for tens of thousands of square meters. Luo Yuan noticed that the underground bones had turned into gray-white bone meal, and he didn’t know how many powerful mutant beasts were buried here.

He suddenly felt a little uneasy. This sea of ​​bones could not have been done by the Huiren tribe. With the bones here, even any mutant beast could destroy the Huiren tribe.

At this time, he faintly smelled a trace of blood. He sniffed gently and looked at somewhere in the sea of ​​bones. Suddenly his face changed drastically. Countless translucent filaments grew from the trunk of the Wisdom Tree, wrapped one of them tightly like a cocoon.

This corpse is obviously quite "fresh". It happened not long ago, and maybe it was even put there yesterday.

His heart became heavier and deeper. The mutant beast did not leave at all. Instead, he went to hunt in the distance. With his own strength, he formed a considerable number of bone seas in the seventh-level mutant beasts. He was definitely not an ordinary seventh-level mutant beast, or even a level 8.

He glanced at the wisdom tree not far away, hesitated for a moment, then moved his body, jumped a few times, and stood by the trunk, not daring to drag it down any longer. God knows when this terrifying creature will come back.

He pulled out the slashing saber, and the 1.5-meter-long sword light sucked violently in the air. In an instant, the sword light flashed like a rainbow and flashed away. Then he retreated with a loud bang. As the huge tree trunk fell, the thick tree trunk began to roll violently like a giant python turning over.

A large number of bones were flying in the air, and the fierce wind blew the nearby trees to fall down one after another. Like cold dripping into boiling oil, the sea of ​​bones was stirred into a pot of thick porridge, and a series of explosions occurred, like rolling thunder. The trunks of these trees were half a meter small, one or two meters thick, and thousands of them were in numbers. Under the fierce rolling and swinging, even the sky was covered. The movements of the Wisdom Tree before its death were simply comparable to a violent seventh-level mutant beast.

Time passed by minute by minute, Luo Yuan walked around in the distance, looking at him anxious, but could only wait patiently.

The wisdom fruit is basically useless to him, but the useful one is the "heart of wisdom".

However, the conditions for the formation of the "heart of wisdom" are quite harsh. Only when the wisdom tree bears irreversible damage, most of the nutrients will shrink from the trunk to a core of the tree.

This is equivalent to a seed. After the crisis, the seed will take root and sprout on the original corpse through the gathering of nutrients and regain its vitality. This is the survival method of the tree of wisdom.
