In the north of Xuanhu City, Ru water flowing from north to south is divided into the left and right (east and west) slabs. The fork estuary forms a water bay with the northern suburbs of Xuanhu City. There are about several hectares of land outside the city, and there are chestnut trees forming forests on it, so the water slab is called Lizhou.

The chestnut trees are lush and green, with Li Tang Shot in the forest. They are usually a place for officials and talented people in Xuanhu City to visit. However, at this time, the chestnut trees on Lizhou have been cut down and Li Tang Shot is replaced by a strong moat.

On the trench, there was an altar that had just been built. The Taoist Wang with his feet and hair was waving the seven-star sword. Many soldiers were watching behind the trench behind the trench.

The last time this "Taozhu Wang" practiced the method of destroying the enemy dam downstream of Xuanhu from the air. This magical power made many people stunned. Although the enemy built the dam for the second time, the government and the army used unique devices to destroy it, everyone was still full of confidence in Taozhu Wang.

The enemy's catapults outside the city had already retreated far away. At this time, there were no other enemy weapons on the field outside the city, so they were not afraid of being attacked. Therefore, there were crowds of people at the head of Xuanhu City, and everyone was waiting to witness the miracle again.

Among the onlookers, King Yuwen of Xiyang was distracted. He looked north with a thousand-mile mirror. It was several miles away from the Rushui River. A river dam had been completed, and the Rushui River section downstream had been cut off. From this, we can see that the upstream dam was storing water.

The enemy wanted to build a dam downstream of Xuanhu twice in a row and return to the city to irrigate water, but Yu Wenwen used the means to destroy the dam. There should be no less than thousands of people killed or injured, but the enemy still did not give up on the water attack.

So he used a lot of manpower and material resources to build a dam upstream to store water, and then release water to rush the city.

It is also water attack, "infusing" and "storing" have different ideas. "Flooding" is similar to boiling a frog in warm water, while "storing" is a wave of flow that directly destroys the city with the rammed earth city wall as a barrier.

How much water is needed to wash out the rammed earth city wall? This is a physics problem, but for actual combat, there is no need to calculate the exact result. Anyway, you only need to build a dam to block the river and store water as much as possible, and then it will break the dam and release the water when it is almost done.

If there are city walls in all parts of the world, most of them are rammed earth walls. If there is enough water that suddenly bursts out and the impact is strong enough, the rammed earth wall is likely to be washed away by the flood. Even after heavy rain, the rammed earth wall will collapse.

Even if the rammed earth city wall can withstand the impact of the flood, the city gate may not be able to bear it. Unless the defenders blocked the city gate from the beginning, it would be difficult to block the erosion of the flood alone by the city gate. Then the city was washed away by the flood and turned into a state of marsh.

However, if it was just a water storage to rush the city, Yu Wenwen would not be afraid because he had confidence in the strengthened Xuanhu City Wall. However, the problem was that the other party's plan should be to rush and pour, so he had to find a way to resolve it.

The project volume was quite large when digging water to attack the city. Yuwen Wen caused the downstream dam to collapse twice in a row. The enemy still did not give up. Not only did they build dams upstream, but also downstream.

But the dam construction address moved downstream for two miles, avoiding Yu Wenwen's "rail cannon" attack range. At the same time, the long encirclement was reinforcing and extending, which was like a circle, wrapping the hanging gourd at the center of the circle.

A long circumference with a circumference of dozens of miles must have a large project volume. Yuwen Wen admired Prime Minister Yuchi Dun very much. The other party was so persistent in using water to reduce casualties in soldiers. He really had a style of loving soldiers like his sons.

Of course, the other party might want to capture him alive, so he would rather spend more time building a dam to build a long circumference, first storing water upstream, then breaking the dam to magnify the water and rushing the city, then dam downstream to dam to cover the river and irrigate the city.

At that time, the hanging gourd will be a pile of soil soaked in water, and will be soaked one day sooner or later.

The Xuanhu City Wall was soaked. When will the day of collapse come?

It took a long time, at least several months, but can Yuchi Dun afford it? It can't afford it.

The earthwork used by the enemy to build a long encirclement came from a circle of trenches of almost the same size. This trenches could prevent the Xuanhu Guard from breaking through the encirclement and prevent foreign reinforcements from breaking into the city.

And to build a long encirclement of the earth obtained from digging the trench directly on the side, that is called by the way.

Yuwen Wen felt that Yuchi Dun was trying so hard to achieve stability, not to spend several months on a long-term confrontation.

More than 100,000 soldiers squatted in Yuzhou for several months and remained motionless. What should I do elsewhere? Put these soldiers into the Tongguan battlefield as soon as possible, attack Guanzhong, or attack Fangcheng, and attack Jingzhou, Shannan. Isn’t it cost more than squatting in a hanging gourd to catch fish for several months?

Yu Wenwen felt that the enemy had built dams downstream of Xuanhu twice in a row, and he should have planned to return water to simmer the Xuanhu. Soak it for ten days and half a month to soften the rammed earth wall, and it would be much easier to smash it at that time.

But after two consecutive failures, more than half a month has passed. Now we are building dams upstream and downstream at the same time, and soaking for another half month, that will be more than a month. Yuwen Wen doesn't care, but will Yuchi Dun not care?

Returning water to soak the city walls and soften the wall foundation. When the effect will come out, it is not accurate. If Yuchi Dun's side succeeds in building a dam for the first time, he can soak it for a month and then attack the city with one go.

But now it has been delayed for half a month, and if the effect is not good, it will take only manpower and waste precious time.

Yuwen Wen thought so, he didn't think that Yuchi Dun would make such a mistake, so he immediately used the Qianli Mile Mile Mile to observe the north. In addition to the river barracks, there was also a large enemy camp at a higher terrain. There should be a large camp in the central army. If Yuchi Dun personally visited the siege battlefield, he would probably be in charge there.

I just don’t know if Yuchi Chifan and Yuwen Weicheng will be there.

Yu Wen Wen was a little distracted when he thought of his wife and children, but now it is not the time to think about it. Now the other party’s camp is a bit far from Xuanhu, and the Qianli Mirror cannot help Yu Wen Wen see the details in the camp clearly.

If Yuwen Wen only looked at the flag, he did not find the emperor's flag, so his wife and children should not be in the camp.

After his eyes swept through the huge camp, Yu Wenwen could not see anything unusual near the enemy camp. Although the Xuanhu City Wall where he was located was high, the terrain of the other camp was also very high, so he could not see how the movements were on the north side of the camp.

A dammed lake should have been formed there, and there should be ships on the lake surface.

Thinking from the perspective of others, Yu Wenwen felt that if he had attacked Xuanhu, he would have consumed a lot of manpower and material resources to build a dam. After building a long encirclement, he would never wait for the flood to destroy the Xuanhu city wall, but would "add some materials" again.

What is the material? A warship full of thunder.

Dig up the weir and release water. The warships floating on the dam are rushing down the river towards the Xuanhu. The water level will be very high at this time, so the ships can easily approach Xuanhu. As long as they are willing to take risks, these warships can directly approach the Xuanhu City Wall.

The dead soldiers riding the boat lit the sky thunder, and then "rumbling", the Xuanhu City Wall collapsed under the dual effects of water pressure and explosion. Maybe it would collapse on a large scale. At that time, the flood broke into the mouth and turned the Xuanhu into a country of marsh.

Such a large water can soak most parts of the city, and the food and grass will become moldy sooner or later.

Yuwen Wen felt that if he had implemented such a tactic, he would have to raise a bet: the charge warship was loaded with thunder, followed by a warship full of soldiers. Taking advantage of the break of the city wall, flooding the city with water, and rushed into the city to attack directly, catching the defenders off guard.

This tactic is extremely risky, because the water flows rapidly when the dam collapses, and it is easy to capsize when the warship passes through the breach, and it is very likely to capsize when it rushes to the city of Xuanhu. However, as long as you are willing to invest your troops, once you succeed, you will definitely win with one blow.

So what the Xuanhu defender had to do at this time was to use sandbags to block the city gates everywhere, and then defend against floods and hit the city walls. The most important thing was to defend against enemy soldiers taking advantage of the opportunity to attack the city on warships.

Putting down the Qianli Mile Mile, Yuwen Wen looked at the altar in front of him. Seeing the Taoist Wang who was working very hard to "do it", he coughed dryly. Zhang Yu, who was beside him, immediately squeezed out of the crowd and shouted a few people waiting next to the awning on the inner wall, "Let them come up."

The sound of gongs and drums sounded, and the soldiers on the top of the city followed the sound and looked at the steps of the city, and then they were stunned: two monsters came out from the awning under the city wall and climbed up the steps.

The two monsters were walking and jumping left and right, looking like gods who danced Nuo opera, but the gods who danced Nuo opera were just wearing masks, and these two seemed to be wearing full costumes and dressed up as monsters.

A monster looks like a chicken. Although his neck is a little longer and looks a little strange, everyone can barely recognize that it is a strange chicken.

But what is the other "tumble"?

In front of everyone, the "tuple" thing next to the strange chicken was climbing up the steps. This thing was shaped like a big egg, but there were five colorful rings on its body, and then there were a pair of exaggerated eyes, all-white eyebrows, and small pupils.

When Yuwen Wen saw these two things walking onto the city wall, his heart was full of evil. In order to make the scene of Taoist Wang retreating to the enemy more grand and lively, he specially created two "mascots" to cheer him up.

One is the "Screaming Chicken", the other is...

I even invited erhu eggs, do you still want to win?!

......

Upstream of Rushui, Beizhai, the rising river water has approached the edge of the camp, but the water level has stopped rising at this time because the river water has stopped at the top of the dam, and to the north of the dam, the original low-lying area is now a vast ocean, forming a dam.

Many warships were moored on the surface of the dams, lined up in several rows. In the front row, in addition to the ships, the cabins were filled with thunder; on the back row, there were a large number of soldiers wearing hard-wielding sharp edges standing, beside them, there were long paddles, hooks and bamboo poles.

No matter which soldier on the ship was holding a bowl of wine in his hand, the fragrance was everywhere, not the kind of fake wine mixed with a lot of water.

A fastboat slowly sailed and was moored in front of the ship formation. Prime Minister and Shu King Yuchi Dun stood at the bow of the ship, holding a bowl of wine in his hand, paying tribute to the soldiers in front of him: "Heroes! I and the emperor are waiting for the good news!"

"I am willing to serve the country!"

"Come on, I've done this bowl of wine! Today's battle to break the city!"

"Dry!!"

Everyone drank the wine in the bowl and then threw the bowl on the deck. The boat that Yuchi Dun was on sailing towards the shore. After he landed on a shore, the sound of drums in the camp sounded loudly, and the atmosphere at the scene gradually became tense.

There are several water gates at the bottom of the dam, with iron cables connected to it, and the iron cables extend to the banks on both sides. As a sound of horns passes, soldiers on the shore pull these iron cables hard. The water gate suddenly opens, and the river water gushs out, and the huge impact drives the dam body out of the cracks, which gets bigger and bigger.

Amid the "boom", the dam built with huge manpower and material resources collapsed. The water roared out of the breach and rushed downstream. The warships on the dam surface moved forward with the water flow. The soldiers on the ship rowed the long oars, turning the formation into columns and preparing to pass the breach in turn.

The first ship was the first to enter the breach. The turbulent water flow made the hull bump. The soldiers on the ship tried hard to control the ship to prevent the ship from crossing at the breach.

The bow of the ship was the first to poke out above the waterfall formed by the collapsed dam. Just when others thought the boat had successfully exited the waterfall, the difference in water levels inside and outside caused the bow to sink sharply. The whole ship "lowed his head" forward and plunged into the water.

The entire ship plunged into the water, and a large number of wreckage of ships surfaced after a while, and the soldiers on the ship who were ignorant of life and death were swept forward by the flood.

Not long after, the second ship sailed out of the waterfall at the breach, and the bow of the ship sank downwards. Then the front half of the hull plunged into the water. Just as the people watching on both sides of the shore made exclamations, the bow floated on the bow, and the entire ship floated completely on the water.

The soldiers on the ship were tilted and wet, but they were still on the deck, because they had tied themselves and the ship together with ropes, and the ship was there, and the ship was there, and the ship was sinking and the ship was dead.

As dead soldiers, they had already put life and death aside. The dam was broken and they had to drive their ship out of the breach. This was the first difficulty. Next, they rushed to Xuanhu City, dived into the water and escaped, and detonated the thunder loaded on the ship and blew the Xuanhu City Wall.

The sky-bang thunder exploded, the city wall collapsed, and a large amount of river water poured into the city along the brigade. At that moment, they might be swept into the city by the river. It was very dangerous, but even if they died, they would be willing to do so.

The Prime Minister has promised to pay three times the pension to their families and waived three years of rent and transfer, so what if you die?

Cheers came from both sides of the strait, which were the onlookers cheering for the deaths to come out of the weir successfully. As the water level difference between inside and outside the weir barn narrowed, most of the subsequent ships successfully came out of the weir and were supported by surging water and rushed downstream to the hanging gourd.

On the high ground, Prime Minister Yuchi Dun watched warships rush out of the dam and rush towards Xuanhu City in the distance. He couldn't help but clench his fists, hoping that he would spend countless manpower and material resources to complete this tactical concept, hoping that he would be able to break Xuanhu today.

Even if you can't get it today, you will still make the Xuanhu City defense on the verge of collapse!

......

The water roared over the sky and hit the wall of Xuanhu City like a heavy hammer. The Yinshi Master stood at the head of the city north of Xuanhu, feeling the vibration under his feet. Although his face was calm, he was uneasy.

Can the rammed earth city wall withstand such an impact? If it withstands the impact, will the city wall collapse in the next long-term soaking?

For the first time, he experienced the power of water attack. Looking at the water in front of him, he was a little weak, not because the Yinshi Master was as timid as a mouse, but because he couldn't swim.

People who can't swim have an irresistible fear of water, but Master Yinshi did not intend to leave the city because he could not afford to lose that person. Even the King of Xiyang came to the city to stabilize the people's hearts, so he had no face to retreat.

Faced with such a thrilling scene, the Yinshi Master was a little worried, but more of the passionate blood was surging. Those who stayed to guard the Xuanhu were not afraid of death, so they would not be afraid of floods!

It was the time when the blood was boiling, the festive sound of gongs and drums made the serious atmosphere very awkward. Master Yinshi had no choice but to look at the altar on the high tower ahead. The Taoist priest was working hard, while two "monsters" were jumping around next to him, their movements were funny and ridiculous.

That weird chicken is fine, but the other monster egg twists around the altar, like a flea on the drum. Many people are not handsome when they see it. The huge pressure brought by the flood to the city to people's psychology instantly dissipates.

It's so ridiculous that he actually relied on this trick to get rid of the enemy!

Yinshi Master thought that the Taoist priest Wang did the trick to destroy the enemy's dam that day, but he was not at the scene, so he did not believe in the other party's magical powers. Later, the King of Xiyang used a "rail cannon" to break the low-collective dam, and he admired him very much.

As a result, today the King of Xiyang invited the King Taoist to the city wall to do the trick. The Yinshi Master wanted to see how the so-called magical powers were.

Just as he was observing carefully, he suddenly saw many warships coming from the water ahead, which was the upper reaches. He was stunned for a moment and figured out the key: the enemy took advantage of the opportunity of the flood to attack the city and took a warship to attack the city!

Many soldiers also discovered this situation. While shouting loudly, Taoist Wang, who was practicing the law on the altar, suddenly howled: "After the law, defeat the enemy!"

As soon as he finished speaking, the monster egg that was twisting and twisting around suddenly slipped, rolled to the side, and almost rolled down from Gaoli. The monster chicken quickly pulled it. After struggling, the monster egg stood up at least.

Such a funny scene swept away the tense atmosphere on the city once again. Wang Yuwen of Xiyang coughed dryly when he saw this, and he felt confident.
To be continued...
