After the channel was cleared, Liu Shiyong first dispatched several small boats to test sailing. He ordered the sailor to stand on both sides with bamboo poles and insert the rod step by step. When the rod head touched the stone, he called the leader to command the helm commander to turn the rudder correctly, avoid the reef, record the location and water depth on the record, and measure the water speed at the same time. Then draw a water map and mark the location of the reef one by one.

After several small ships were successfully tested and the navigation map was made, everyone breathed a sigh of relief, but they were still uncertain whether the medium-sized warship could pass. The medium-sized warship ranged from 1,500 stones, and the length and width were much larger than the small warships. The flexibility and handling were much worse, so the newly opened small waterway boats could pass, but the medium-sized warships might not be.

"I am the general's ship first. After success, you will be with you!" Seeing that the generals still had doubts, Liu Shiyong smiled and issued an order.

"Supervisor Du is the leader of the army. How can he take the risk? I am willing to take the lead in trying out the voyage!" Peng Hui, the commander of the advance fleet, stepped forward and bowed and asked.

"I am not talented, and I am willing to try it out, even if I die, I will never regret it!" Zhou Ping, the commander of the accompanying guard gunship, also asked for his order.

"No need to fight anymore. My commander's ship has the largest hull. As long as this ship can pass through, the entire Western Expedition fleet can pass through this dangerous shoal. Moreover, I commander is the Yangtze River Defense Commander, leading by example is both a duty and a duty!" Liu Shiyong waved his hand and said in an unquestionable tone.

"This... I will obey the order!" Everyone knows that the warship Liu Shiyong was riding at a length of 18 5 feet and 3 1 ft. It is a bit fatter than a sea boat. The ship has three floors and can carry 400 soldiers, carry equipment, or more than a thousand stone cargo. The ship is driven by five pairs of oars. From the stern to the two-story power cabin, five cows push the cone wheel as the power of the ship. It can travel 500 miles a day on the water with stable water. This type of vehicle is the main warship of the Western Expedition fleet. As long as it can pass, other warships are naturally no problem. Seeing that they are determined, everyone can only obey the order.

Liu Shiyong ordered all unrelated people on the boat to get off the boat, leaving only the sailors who were driving the boat. He stood in the cockpit to supervise the battle. The general spared no effort, and the soldiers and generals below naturally used their lives. The two Taiwanese troops were inspired by their courage and also boarded the boat to guide him. Following the instructions of the Taiwanese troops, he did not walk through the Nan Cao, which was densely reefed, and the Bei Cao, which was relatively turbulent and the big pearl was standing tall.

Liu Shiyong listened to the words of the Tan Master, and did not dodge the Wacao Shui, but followed his instructions and boldly drove the boat towards the Wacao Shui in front of the big pearl stone. Sure enough, this move avoided the danger of the warship hitting the stone. The ship broke through the deep waters opened and turned the risk into a barrage. The two Tan Masters who had always ruddered over Kongling for wooden boats, unexpectedly, the high-ranking general quickly mastered the skill of rushing to Wacao Shui, and all admired his courage.

The coached ship successfully passed through Kongling dangerous shoals, breaking the curse that the Thousand Stone ship could not go upstream, and it is of great significance. This not only opened up the path to the Western Expedition, but also opened the waterway to the upper reaches of the middle reaches of the Yangtze River, so that soldiers and materials could be sent to Sichuan and Sichuan continuously to support the Western Expedition. At the same time, a commercial bridge was built between Sichuan and Sichuan and Jiangnan, reducing transportation costs, and conducive to the circulation of materials between the two places and the mutual exchange of existence or non-existence.

The advance fleet broke through Kongling Beach one by one. Liu Shiyong knew that the opportunity was not missed. He ordered people to report to Wen Tianxiang to lead the brigade through the beach as soon as possible, and left several water diversion and water maps to guide the brigade through the beach. On the other hand, the whole team continued to go west because there was a more terrifying Qingtan ahead. Only by breaking through this dangerous beach can the troops enter the province and seize this strategic point...

"Master Qian, do you think this silver reward biting your hand or you think it's too little?" After arranging everything, the fleet set sail again. Under the full force of the ten cows, the oars rotated at high speed, urging the warship to move forward, but with the offset of the flowing water, the speed was not fast. Liu Shiyong talked to the old beach master in the cabin, and the silver reward he paid as promised on the table, but he refused to accept it. He asked in surprise.

"How dare you call me Master in front of Du Shuai? Such a name means killing the grass people." Laotan teacher Qian Shuisheng said again, "I dare not accept Du Shuai's reward, but I will take it back."

"How can I say that my father-in-law has given advice to me and cross Kongling Beach? Is it impossible? My father-in-law will do what he said. Even if he accepts it, he will rely more on it in the future!" Liu Shiyong thought it was the old man who was worried that he would find a debt, so he said with a smile.

"It's handsome, it's not that the young man doesn't want it, but the Qingtan ahead is more thrilling than Konglingtan. I'm really worried about having a life of profit, but not having a life of life. Please give me a way out!" Qian Shuisheng begged repeatedly.

"Brother-in-law, what do you mean?" Liu Shiyong was timid when he saw a master like Qian Shuisheng, and felt a terrified heart. He realized that the future must be more difficult than his own idea. He waved his hand to signal him to sit down and ordered his personal soldiers to watch the tea.

"Du Shuai may not know something. His predecessors once had a warning: Since ancient times, there has been a saying that there is new (south) and no leakage (south), there is no leakage, and there is also a rising water-raising beach and a clearing water-reducing Qingtan." Qian Shuisheng said.

"Please explain in detail!" Liu Shiyong has been working in the Huai River for a long time. He really doesn't know the water conditions of the Yangtze River, but he also knows that the Three Gorges of the Yangtze River are three dangerous shoals, and Qingtan is one of them, so he humbly asks for advice.

"Du Shuai, Qingtan was named Haosanxia in ancient times. It is about four miles long and consists of Toutan, Ertan and Santan. The reason why Qingtan is also called Xintan is because the mountains collapsed during the Jin and Han dynasties, so it is called Xintan." Qian Shuisheng said after thanking him.

"Well. Fan Chengda of this dynasty went to Sichuan as the commander of the General Office, and there is indeed such a record in his book "The Book of Wu Chuan". Lu Jiaxuan also mentioned in "The Record of Entering Shu", saying: On both sides of Xintan are called Guancai in the south and Longmen in the north. Longmen water is particularly turbulent and has many dark stones; the official cabin is feasible, but there are also many sharp stones. Therefore, it is the most dangerous place in the gorge." Liu Shiyong nodded and knew that his words were true.

"Du Shuai has already heard of it, and naturally the most dangerous boating in Zhiqingtan is in the season when there is little water. During the rainy season, the flood is discharged, the water rises and the beach is flat, the water is relatively stable, and there is no major danger in the boat. In the dry season, the river water falls and the water falls out, forming a steep ridge and falls. The head beach will have a steep ridge, which is shaped like a waterfall in the river. There are three pointed stones lying on the center of the river to block the middle flow, and there are also balance stones that are like a balance blocking the river water flow. When sailing, you must go through the winding and gentleness before you can cross the beach. When the boat goes here, it is like an arrow that breaks the string and flows down. If you are not careful, the boat will be destroyed and people will die. There are countless small boats here. In the early years, when there were too many ships, the boat capsized almost every day. Even if it capsizes four or five, it is not rare!" Qian Shuisheng said in the end and said in a deep and painful expression, and his words were deep and he said.

"If we imitate the method of Konglingtan to clear the waterway with gunpowder?" Liu Shiyong pondered for a moment and said.

"They are handsome, not necessarily feasible!" Qian Shuisheng sighed and said, "The power of gunpowder is small. But the bleaching beach is caused by the collapse of the mountains and cliffs on both sides. The huge rocks rolled down the Yangtze River and crossed the middle of the river, forming a hard rock layer of more than 30 feet long on the south bank of the beach, forming a straw rock stone. The exposed sword stones appear and disappear from time to time on the face. In addition, a large number of stones rushed over from the river north of the beach, silting into a huge moraine dam, extending to the center of the river. The upper and lower wings confronted the straw rock stone and the radial crooked stone on the south bank, blocking the water to form a beach. The river is full of stones, and there are bleaching pillows and beds. When the water falls, the stones come out, and when the water rises, it seems to be visible and hidden, forcing the water to form a whirlpool, and the whirlpool flows very large." Therefore, the beach is dangerous and the boat passes by, which is thrilling!"

"Such a large area of ​​stones is hidden under the turbulent water flow, and it is indeed difficult to discharge them with gunpowder." After hearing this, Liu Shiyong frowned. He knew that this was no different from being in Kongling Beach, where the huge rocks were exposed to the water, and soldiers could climb on it to work and place gunpowder. But if it was under the water, it would be powerless. In the turbulent flow, people could not stand footing and the boat could not moor. But he asked unwillingly.

"Yes!" Qian Shuisheng said, "The old man once heard from his elders that during the Renzong period, a large-scale landslide and rock collapse occurred in Qingtan, which caused the river to be cut off for 21 years. At that time, ships upstream and downstream of Qingtan were bounded by Qingtan and traveled on one side, without going back and forth. At that time, ships would have to be moored when they arrived in Qingtan, passengers would have to go ashore when they arrived in Qingtan, and goods would have to be transported when they arrived in Qingtan. As a result, the rise of "Pantan" actually formed a market, and today's Qingtan Town was created."

"Pantan?!" Liu Shiyong said in a little puzzled manner.

"Du Shuai didn't know that "trading" in the local area means moving. In ancient times, when boating across the beach, sometimes it was necessary to use pulling fiber to go to the beach. In order to make the boat light, the cargo on the boat had to be unloaded to the shore first and transported to the other end of the beach by manpower. When the empty ship was pulled over the beach by the trainer, the original cargo was shipped onto the boat. Sometimes it was dangerous for the ship to go to the water and put it on the beach, and merchants often chose to go to the beach to ensure the safety of the cargo." Qian Shuisheng explained.

"Oh, a business can actually make a town. How did the father-in-law pass the beach at that time?" Liu Shiyong did not expect that an unexpected disaster could actually make an industry rise and form a town. It seems that good and bad luck depend on each other but it makes sense, so he asked with a lucky heart.

"Du Shuai, during the dry season, the river water fell, and the Qingtan Beach River became a comb back overnight, so the river flow ripped and swirled in the middle of the reefs, forming whirlpools, either light or dark. At this time, the boat passed by Qingtan. If it was a countercurrent boat, the fibers would be increased exponentially. And the rudder should be removed to reverse the boat, with the tail facing up, head facing down, and upside down, so as to reduce the resistance to the beach on the boat. If it was a downstream boat, the hull would need to be horizontal so that the hull would be perpendicular to the river flow, so that the area of ​​contact with the vortex surge was increased and the area of ​​the vortex surge was increased and the safety was added. But even if people were so careful, ships would still be swallowed by Qingtan from time to time." Qian Shuisheng licked his lips and explained.

"In this way, if the method is right, a large ship can pass the beach, but be careful of whirlpools and reefs. If you have enough fibers to pass the beach!" Liu Shiyong said happily after hearing this.
