?Yuwen Wen was watching the troops crossing the river by the floating bridge downstream of the mouth of the Lianghe River, and accidentally discovered a situation that seemed inconspicuous at first glance: the water level of this river is strange!

Several miles upstream of the floating bridge is the estuary after the two rivers converge, which is called the estuary of the two rivers. The estuary is forked into the character "Ya", the left fork is "Yu Shui" (the Bai River in later generations), the upper reaches is Jiyang City, the capital of Xinye County, Jingzhou, and the right fork is "Bishui (the Tang River in later generations), and the upper reaches of Xinye County also flow through the boundary of Xinye County.

After the convergence of the two rivers, it is the Tangbai River in later generations. The Tangbai River extends southwest and finally flows into the Han River about ten miles east of Fancheng.

It is July now in the rainy season. Logically speaking, the water level of the river should be relatively high. After all, the water volume of the two upstream rivers will only increase after the sharp increase in water. So why does the water level of the river look a bit low now?

A large amount of muddy soil appeared by the river as if it had just come out of the water. Although Yu Wenwen had never been to this river, he always felt that the original water level should be much higher when looking at the wet mud by the river.

Xu Shao agreed with him after hearing what he said, but Xu Shao had no experience in marching and fighting. The ones he had seen the most were the Fu River next to Anlu City and the river next to Xiaochang in Yuezhou Prefecture. He didn't know what the fluctuation range of the water level reached, which was abnormal.

The guards of the pontoon bridge could not answer this question because the soldiers were from Anzhou and there were no locals, and no one knew what the normal water level of this river was at this time of year.

Local people knew that there was a war about to happen, and they moved their families to other places to avoid the war. They went there for a while but couldn't find anyone to ask.

Regarding this topic, Zhang Yu, the former Xiangyang Navy’s ‘cannon fodder’, had something to say.

He used to be a low-level soldier in the Xiangyang Navy Army. Everyone lived in a difficult and had a poor salary after layers of deductions. His stomach was so poor that he couldn't eat enough. He was often called by Shangguan to do hard labor and consumed a lot of money.

Fortunately, there are boats, so the navy soldiers usually work part-time as fishermen, or fishermen work part-time as Xiangyang navy. They row boats privately to fish to subsidize their family income.

In theory, as a navy soldier, he was not allowed to leave the water camp without rowing a boat without leaving the water camp without leaving the water camp without permission, but the navy generals turned a blind eye to this situation.

The soldiers have been exploited for a long time and are forced to continue, and they may cause a mutiny to be a loss, but the generals will not miss this opportunity to pluck their feathers by the way.

Whenever the soldiers come back secretly, they have to charge the closure fee - using fish to pay for it, so the largest, most fat and best fish that come back online have to be handed over.

If you dare not hand over, you will be punished for illegally exchanging military ordnance for violating military discipline and leaving the water camp without permission. Take it out in public and fight fifty whips so that everyone knows what military discipline is like!

Ordnance is a naval warship, or a naval warship that is also a fishing boat. Zhang Yu was picked up by his adoptive father by his adopted father by his family. The family was poor and even the broken wooden house in the water village did not live on a small broken boat.

Later, Zhang Yu was killed by the team leader Li, and he lived with his family. The waters on the Han River were deep and inconvenient to cast a net, so they often took advantage of the night to cross the Han River to the river northeast of Xiangyang to fish.

The family struggled to survive by secretly catching fish for food and selling it on the market. So Zhang Yu was very familiar with this river, but he didn't pay attention to this issue when crossing the river until he heard Yuwen Wen and Xu Shao discussing this matter.

"There is indeed a problem with the water level." Zhang Yu felt that the current water level was at least 30% lower than the water level in the previous few years. Speaking of this, the guard seemed to remember what he said that when the pontoon bridge was set up a few days ago, he remembered that the situation was a little different from now.

The main body of the pontoon bridge is a large row of wooden boats that run side by side across the river. The two ends of each boat are fixed with iron cables with other boats. There are bamboo rows and wooden boards between the wooden boats and cabins so that people, horses and chariots can pass through.

The so-called difference is very simple. The wooden boat that was originally closest to the head on the east coast was floating on the water. Now, let alone the first boat, even the third boat that went west, has been stranded.

However, he disagreed with the issue that Xiyang County Duke was confused about. If the water level of the floating bridge is higher or lower, there are still some problems floating on the water surface. It is rare for rich men to be seen!

Yuwen Wen, who had always been "dark in his psychology" in the march and war, didn't know what to say, but just urged the troops to seize the time to cross the river. Seeing that all the members arrived on the west bank, the grain team was about to start crossing the river, so he took Xu Shao to the floating bridge.

As he walked, Yuwen Wen couldn't help but think of anecdotes about this river. The left fork of the upper reaches of the Tangbai River is the Qingshui (the Baihe River in later generations). From the estuary, it is about eighty or ninety miles away. The capital of Xinye County is Jiyang (that is, near Xinye in the Han Dynasty).

Baihe, Xinye... I'll do it, the Romance of the Three Kingdoms, reply: Zhuge Liang burns Xinye!

The second brother Guan used sandbags to build a dam several miles away from the upper reaches of the Baihe River in Xinye. Cao's army, who occupied Xinye City, was so angry that his eyebrows were gone, his mouth was dry, and the group of people ran to the Baihe River to drink water. Then Liu Bei's army in the upper reaches pulled the sandbags away from the Baihe River and rushed towards Cao's army downstream. He took it away.

Thinking of this, Yuwen Wen looked at the upstream direction in a striking and suspicious manner. He thought that if the Jingzhou army really built a dam to store water and played water attack, it would be possible to flood the Anzhou army: When more than 100,000 people crossed the river a few days ago, you would have to wait until now to break the dam?

Marshal Liang Shiyan flooded Yuwen with two thousand "armys"? Just kidding!

Yuwen Wen felt that he was thinking too much, so he shook his head and continued to walk forward. As he walked, he felt something was wrong: a roar came from the north, as if it was getting louder and louder.

"Is it a fellow Taoist who has overcome the tribulation?" Yuwen Wen looked up at the sky and found that there were no suspicious clouds in the thousands of miles of clouds. Then he was grabbed by someone with his left hand and then the man pulled him forward.

"Master Lang left quickly, it's flooding!" Zhang Yu grabbed Master Lang Yuwen's hand and pulled him to rush towards the west bank in front. Before Yuwen Wen could come back to his senses, he saw Xu Shao running too.

"how..."

Before he finished speaking, he felt that the floating bridge under his feet was waving and there seemed to be a force supporting the entire floating bridge upwards. He shook his heart and turned his head north and saw waves of white waves rushing towards him.

"I'm not even enough for three thousand people, are you wrong?" Yu Wen Wen understood what was going on and broke free from Zhang Yu's hand and ran forward hard. He and Xu Shao and Zhang Yu were in the recruit camp for five months, with strong bones and neat legs and running fast.

But the main reason is that they are close to the west coast, so when they rushed down the pontoon bridge and rolled and climbed to the shore, the surging water swept over the pontoon bridge, and the power of nature actually took the pontoon bridge away with a wave of flow!

The defenders on both sides were stunned to see this scene. The floating bridge was swallowed by the sudden flood just now, and the river water level rose sharply. Fortunately, the terrain of the camps on both sides was relatively high and not affected.

But after the roaring water passed, the water level slowly dropped, no trace of the pontoon bridge was seen again. The two cross-river iron chains locked on the pontoon bridge and the wooden boats forming the pontoon bridge disappeared.

The four large wooden stakes firmly nailed into the soil on both sides of the river to fix the pontoon bridge are gone, leaving only empty deep pits. The two iron chains that were originally specially pulled up to protect the pontoon bridge are still there.

It can only be said that it is still there, and the two iron cables each cut off one end and only the other end is connected to the wooden stake on the shore.

"The resistance of the pontoon bridge is too great, so it was taken away by a wave of flow..." Yu Wen Wen murmured to himself as he looked at the riverside. Everyone around him looked at the riverside in a daze, no one asked what Xiyang County Duke said, "The resistance of the pontoon bridge is too great".

It is confirmed that it is a water attack! But what does the other party want to do?

A few days ago, if more than 100,000 people crossed the river from here, if more than 100,000 people came to such a water attack just halfway through, then the Anzhou army could be cut off in half. Then the Jingzhou army, which was ambushing on the west bank, could take the opportunity to attack the Anzhou army that also remained on the west bank.

But this did not happen but only means that the Jingzhou army did not arrive nearby to ambush. Now the flood is definitely man-made, that is, the Jingzhou army upstream built a dam to block the water and attacked the water.

Yuwen Wen felt that there were two possibilities: the first was to attack the floating bridge, and the second was that the Jingzhou army built a dam and broke the dam.

He didn't think he was lucky, so comprehensive judgment was the first possibility. Chen Wudi, Yang Ji, Xu Shao and others also agreed with this view.

Anzhou Army’s land grain route has an important node, which is this floating bridge. The grain transported from the east must pass through this floating bridge to cross the river to support the Anzhou army on the west bank.

Because the Anzhou army attacked Jiyang, Xinye County, Jingzhou, and Rangcheng, Jingzhou, also needed to go north on the west coast, the floating bridge must be kept open until Anzhou captured these two important places and defeated the imperial army.

It may take more than a month, so it is important to protect the pontoon bridge. If the bridge is broken, it will only take a few days to rebuild the army's own grain storage during this period and it will be affordable to ensure self-sufficiency.

So the other party wanted to make the bridge break and never be able to repair it again, so what they had to do next would be obvious.

"There are enemies, and there are enemies in the northwest direction!" The sentry on the camp on the west side beat the gong and shouted desperately, and then the sentry on the camp on the east bank shouted the same message.

Yuwen Wen asked the army leader Chen Wudi to organize soldiers to prepare for formation, and asked the head of the pavilion Xu Shao to organize auxiliary troops to push all the baggage into the camp. He entered the camp together to meet the guards.

This time, the Fuqiao defenders were divided into two villages, east and west. Because the Xizhai was facing greater pressure, the main general led 15,000 troops to station in Xizhai, and 5,000 people from the East Village were responsible for supporting them.

The head general is another Sima of the Anzhou General Administration: Zheng Wanqing. He was the governor of Wenzhou in July last year because he was the confidant of Yuwen Liang, and he has been promoted to Sima of the General Administration. This time, he will bear the important task of guarding the floating bridge.

Zheng Sima and Yuwen Wen were very familiar with each other. When Yuwen Wen recruited troops and started training in February this year, he would handle all the relevant military affairs. When they met, they didn't care about greetings and hurriedly climbed the enemy tower together to observe the enemy situation.

The dust was flying in the northwest. It seemed that there were thousands of troops coming here, but they were far away and not very clear. But for Yuwen Wen, this was not a problem. He took out the Qianlijing and looked at the northwest. Then his expression was solemn. Zheng Sima next to him took the Qianlijing he handed over and looked over there, and he frowned:

The flags in the vast army are like the sea, and one of them is very conspicuous with a black gold-backed edge. Seven gold-plated characters are written on it: Liang, the Marshal of the South Marshal.

Excluding the trick of pulling the banner and becoming a tiger's skin, the opposite side should be the main force of the southern army heading south. The commander is the marshal Liang Shiyan. If all the troops under his command are in front of him, there will be at least 150,000.
