In the north of the city, the water of Ru flowing from north to south is left and right (east and west), and the fork and the northern suburbs of the city form an inlet, during which the land outside the city is about several hectares, and there are chestnut trees into forests, so the water is called Lizhou.

The chestnut trees are lush and green, and there are chestnut hall shooters in the forest, which is a place for officials and talented people to play in the hanging gourd city on weekdays, but at this time, the chestnut trees on Lizhou have been cut down, and the chestnut hall shooter is replaced by a strong moat.

On the base, a just-built altar, the king Taoist priest with his feet and hair is wielding the seven-star sword, and many soldiers are watching the city behind the base.

The last time this "Wang Dao Chang" practice, the air will be the enemy weir dam downstream of the hanging gourd collapsed, so miraculous power made many people stunned, although the enemy army built the dam for the second time, it was the official army with a strange device to destroy it, but everyone is still full of confidence in Wang Daochang.

The trebuchets of the enemy army outside the city have long been withdrawn far away, and there are no other enemy weapons in the field outside the city at this time, and they are not afraid of being attacked, so the head of the hanging city is now crowded with people, and everyone is waiting, waiting to witness the miracle again.

In the crowd of onlookers, Xiyang Wang Yuwenwen was distracted, he looked north with a clairvoyant mirror, it was a few miles upstream of the Rushui, a barrage has been completed, and the downstream section of the Rushui River has been cut off, so it can be seen that the upstream weir is impounding.

The enemy army tried to build a dam downstream of the hanging gourd twice in a row to backwater the city, but Yuwenwen used means to collapse the dam, and there should be no less than thousands of casualties, but the enemy still did not give up the idea of water attack.

Therefore, he did not hesitate to use a lot of manpower and material resources to build a dam to store water upstream, and then release the water to rush the city.

It is also a water attack, 'irrigation' and 'rushing' are different ideas, 'flooding' is similar to boiling frogs in warm water, while 'rushing' is a wave of streams, directly using the rammed earth city wall as a barrier to break down.

How much water does it take to break down a rammed earth wall? This is a physical problem, but for actual combat, there is no need to calculate accurate results, anyway, just build a dam to barrage the river to store as much water as possible, and look like it is almost the end of the embankment to release water.

If there are city walls in various parts of the world, most of them are rammed earth walls, if the sudden outbreak of large water is large enough, the impulse is strong enough, the rammed earth city wall is very likely to be washed down by the water, and even after heavy rain, the rammed earth city wall will collapse.

And even if the rammed earth city wall can withstand the impact of the water, the city gate may not be able to withstand it, unless the defenders block the city gate at the beginning, it is difficult for the city gate alone to block the washing of the water, and then the city is washed by the water and becomes a mess.

However, if it was just to store water and rush the city, Yuwen Wen was not afraid, because he was confident in the strengthened hanging gourd wall, but the problem was that the other party's plan should be both flushing and irrigating, so he had to find a way to resolve it.

Diverting water to attack the city, the amount of work is not small, and Yuwenwen let the downstream weir burst twice in a row, and the enemy still did not give up, not only building a dam upstream, but also building a dam downstream.

It's just that the dam construction site has been moved two miles downstream, far away from the attack range of Yu Wenwen's "railgun", and at the same time, the long perimeter has been re-strengthened and extended, which is like a circle, wrapping the hanging gourd in the center of the circle.

A long perimeter of dozens of miles, its amount of work is definitely not small, Yu Wenwen admires Prime Minister Wei Chi Dun very much, the other party is so persistent in attacking with water to reduce the casualties of soldiers, it is really quite a style of loving soldiers like a son.

Of course, the other party may want to capture him alive, so he would rather spend more time building a dam and building a long fence, first storing water in the upper reaches and then breaking the embankment to amplify the water to rush the city, and then the downstream weir dam will hold the river water and irrigate the city.

At that time, the hanging gourd will be a mound of earth soaked in water, and sooner or later it will rot.

When will the day come when the hanging walls will be soaked and collapsed?

It's been a long time, at least a few months, and can Wei Chidun afford it? Can't afford it.

The earthwork used by the enemy to build the long encirclement came from a circle of trenches of almost the same size, which prevented both the overhanging defenders from breaking through and the reinforcements from breaking into the city.

And the earthwork obtained from digging trenches is directly piled up on the side to build a long enclosure, which is called incidental.

Yu Wenwen felt that Wei Chi was so tossed in order to seek stability, not to spend months in a long-term confrontation.

More than 100,000 soldiers have been squatting in Yuzhou for months without moving, what to do elsewhere? Throwing these soldiers into the Tongguan battlefield as soon as possible, attacking Guanzhong, or attacking Fangcheng and attacking Jingzhou, Shannan, is it not more cost-effective than squatting in the hanging gourd to fish for a few months?

Yu Wenwen felt that the enemy had built a dam in the downstream of the hanging gourd twice in succession before, and it should indeed be planned to backwater to fill the hanging gourd, soak it for ten days and a half months to soak the rammed earth city wall softly, and it would be much easier to smash it up at that time.

But after two successive failures, more than half a month has passed, and now it is building dams upstream and downstream at the same time, and soaking for half a month, that is, more than a month has passed, Yuwenwen doesn't care, but Wei Chidun doesn't care?

The backwater irrigation of the city wall base soaks soft, when the effect comes out is not accurate, if the first dam of the Wei Chi Dan side is successful, you can soak for a month and then attack the city.

But now it has been delayed for half a month, and if it is soaked for another month, in case the effect is not good, it will be a waste of manpower and precious time.

Yuwen Wen thought so, he didn't think that Wei Chi Dian would make such a mistake, and then used the clairvoyant mirror to observe the north, where in addition to the barrage, there was also an enemy camp on higher ground, which should be the Chinese army camp, if Wei Chi Dian came to the siege battlefield in person, he would probably sit there.

I just don't know if Yu Chi Chifan and Yuwen Weicheng will be there.

Yu Wenwen was a little distracted when he thought of his wife and children, but now is not the time to think about it, now the other party's camp is a little far away from the hanging gourd, and the clairvoyant mirror can't help Yu Wenwen see the details of the camp clearly.

If you just look at the flag, Yu Wenwen didn't find the flag of the Son of Heaven, so his wife and children should not be in the camp.

His eyes swept over the huge camp, Yu Wenwen couldn't see anything unusual near the enemy's camp, although the hanging wall he was on was high, but the terrain of the opponent's camp was also very high, so he couldn't see the movement on the north side of the camp.

A dammed lake should have formed there, and on the surface of the lake, there should be boats.

Thinking about it from another perspective, Yu Wenwen felt that if he attacked the hanging gourd by water, after spending a lot of manpower and material resources to build a dam and build a long fence, he would never wait for the water to collapse the hanging gourd wall, but would have to "add some materials".

What is the material? A warship laden with thunder.

The water level will be very high at this time, so the ships can easily approach the hanging gourd, as long as they are willing to take risks, these warships can directly approach the hanging gourd wall.

The dead man who drove the ship ignited the thunder, and then after the "boom", the hanging gourd city wall collapsed under the dual action of water pressure and explosion, and it was not good to collapse a large area, and then the water broke in, turning the hanging gourd into Zeguo.

Such a large flood can soak most of the city, and the grain and grass will be flooded, and sooner or later it will become moldy.

Yu Wenwen felt that if he implemented such a tactic by himself, he would have to make a big bet: the charging warship was full of thunder, followed by the warship full of soldiers, taking advantage of the breach of the city wall and the flood to flood the city, he directly rushed into the city to attack, and caught the defenders off guard.

This method of warfare is extremely risky, because the current is turbulent when the dam bursts, and it is easy for the ship to capsize when it passes through the breach, and it is very likely to capsize when it rushes to the bottom of the Hanging Fortress, but as long as you are willing to invest your troops, once you succeed, you will definitely win with one blow.

Therefore, what the defenders of the hanging gourd had to do at this time was to block the gates of the city with sandbags, and then defend against the flood to attack the city wall, and the most important thing was to defend the enemy soldiers from taking the opportunity to attack the city by warships.

Putting down the clairvoyant mirror, Yu Wenwen looked at the altar in front of him, and saw the Wang Taoist priest who was working very hard to "practice", he coughed dryly, and Zhang Yu on the side immediately squeezed out of the crowd and shouted a few times to the few people waiting next to the pergola on the inner side of the city wall, "Let them come up".

The sound of gongs and drums sounded, and the soldiers at the head of the city followed the sound to the steps of the city, and then they were stunned: two monsters from the pergola under the city wall came out and climbed the steps.

The two monsters jumped left and right while walking, looking like gods dancing in the play, but the gods who danced the show were just wearing masks, and these two seemed to be people dressed as monsters in full costumes.

A monster resembles a chicken, and although it has a longer neck and a strange appearance, everyone can barely recognize that it is a strange chicken.

But what is that other "lump"?

In front of everyone's eyes, the "lump" thing next to the strange chicken is climbing the stairs, this thing is shaped like a big egg, but there are five colored rings on its body, and then there is a pair of exaggerated eyes, all white eye bubbles, small pupils.

Yu Wenwen saw these two things walking up to the city, his heart was full of bad taste, in order to make the scene of Wang Daoshi's retreat from the enemy more grand and lively, he specially made two "mascots" to help the fun.

One is a "screaming chicken", the other is ....

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

。。。。。。

In the upper reaches 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 has not passed the top of the barrage, and the north of the barrage, the original low-lying area is already an ocean at this time, forming a dammed lake.

Many warships were moored on the dammed lake, lined up in several rows, and in the front row, in addition to the sailing soldiers, the cabins were also full of thunderstorms; On the boat in the back row, there were a large number of soldiers in strong clothes standing, surrounded by not only weapons, but also long trees, hooks, and pennies.

No matter which ship the soldier is, at this time he is holding a bowl of wine in his hand, and the aroma of wine is overflowing, not the kind of fake wine mixed with a lot of water.

A fast boat slowly approached, anchored in front of the ship array, and the prime minister and the king of Shu stood at the bow of the ship with a bowl of wine in his hand, and saluted the soldiers in front of him: "Strong men! The widow and the Son of Heaven are waiting for good news! ”

"Someone is willing to serve the country!"

"Come, dry this bowl of wine! Break the city today! ”

"!!"

Everyone drank the wine in the bowl, and then threw the bowl on the deck, and the small boat in which Wei Chidun was riding sailed to the shore, and when he landed, the drums in the camp were beating, and the atmosphere gradually became tense.

There are several water gates at the bottom of the dam, which are connected with iron cables, and the iron cables extend to the banks on both sides, as a horn sounds, the soldiers on the shore struggle to pull these iron cables, the water gates suddenly open, the river gushes out, and the huge momentum washes the dam out of the cracks, and the cracks are getting bigger and bigger.

In the sound of "boom", the weir dam built with huge manpower and material resources burst, and the water roared out of the breach and surged downstream, and the warships on the dammed lake moved forward with the current, and the soldiers on board rowed the long swords, so that the formation became a column, ready to pass through the breach in turn.

The first ship was the first to enter the breach, and the turbulent currents caused the ship to jolt, and the soldiers on board tried to hold the ship in the direction to prevent the ship from crossing the breach.

The bow of the ship was the first to poke out of the waterfall formed by the dam failure, and just when others thought that the ship was successfully out of the waterfall, the difference between the water level inside and outside caused the bow to sink sharply, and the whole ship "bowed" forward and plunged into the water.

The whole ship was plunged into the water, and a moment later a large number of wrecks surfaced, and the soldiers on board were swept forward by the water.

Not long after, the second boat sailed out of the waterfall at the breach, and the bow of the boat sank downward, and then the front half of the boat plunged into the water, and when the onlookers on both sides of the river exclaimed, the bow floated, and the whole ship floated completely on the water.

The soldiers on board were staggered and soaking wet, but they were still on deck, for they had tied themselves to the ship with ropes, and the ship was in the hands and the ship was sinking.

As the dead, they have already put life and death aside, the weir breaches, they have to drive the boat out of the breach, this is the first difficulty, and the next, is to rush to the city of Hanging Gourd, before jumping into the water to escape, detonate the ship full of thunder, the city wall of the Hanging Gourd.

The thunder exploded, the walls collapsed, and a large amount of river water poured into the city along the breach, and at that moment they might be swept into the city by the river, which was dangerous, but even if they died, they would not hesitate to die.

The prime minister has promised to give their family a triple pension and a three-year rent waiver, so what about death?

There were cheers on both sides of the river, that is, the onlookers cheered for the dead soldiers to get out of the weir smoothly, and with the narrowing of the water level difference between the inside and outside of the weir, most of the follow-up ships successfully got out of the weir, were supported by the surging water, and rushed downstream.

On the high ground, Prime Minister Lieutenant Chi Dian watched the warships safely rush out of the dam breach and rush towards the distant Hanging Gourd City, he couldn't help but clench his fists, and looked forward to it in his heart.

Even if you can't take it today, you have to make the defense of the Hanging Gourd City on the verge of collapse!

。。。。。。

The water roared overwhelmingly, like a heavy hammer smashing on the city wall of the hanging gourd, and the Yin Shishi stood at the head of the city on the north side of the hanging gourd, feeling the vibration under his feet, although his face was calm, but his heart was uneasy.

Can rammed earth walls withstand such impact? If it withstands the impact, will the walls collapse in the following long immersion?

For the first time, he experienced the power of water attack, looking at the big water in front of him, to be honest, his feet were a little weak, it was not that the Yin World Master was as timid as a mouse, it was really because he couldn't swim.

People who can't swim have an irrepressible fear of water, but the Yin Shishi didn't plan to leave the city, because he couldn't afford to lose that person, and even the King of Xiyang came to the city to stabilize people's hearts, where did he have the face to retreat.

In the face of such a thrilling scene, the Yin Shishi was a little apprehensive, but more of them were full of blood, and the people who stayed behind to guard the hanging gourd were not even afraid of death, where would they be afraid of the big water!

It was when the blood was boiling, the festive gongs and drums made the serious atmosphere embarrassing, and the Yin Shishi had no choice but to look at the altar on the high base in front of him, the royal Taoist was working hard, and the two "monsters" were jumping around beside them, their movements were funny, making people cry and laugh.

The strange chicken was not enough, and the other strange egg writhed around next to the altar, like a flea on a drum, many people looked handsome or not, and the huge pressure brought by the flood to people's psychology dissipated instantly.

It's ridiculous to rely on this kind of trick to retreat from the enemy!

Yin Shishi thought so, that day Wang Taoist did to destroy the enemy's weir, he was not at the scene, so he didn't believe in the other party's supernatural powers, and later what "railgun" did the king of Xiyang use to break the low weir dam, he admired it tightly.

As a result, today the King of Xiyang invited the Taoist priest to the city to practice, and the Yin Shishi wanted to see how the so-called supernatural powers were.

Just as he was carefully observing, he suddenly saw many warships sailing in front of him, that is, on the upstream water, he was just stunned for a moment, and then figured out the key: the enemy army took the opportunity of the big water to attack the city and attack the city by warship!

Many soldiers also discovered this situation, and when they were shouting "enemy attack", the Taoist priest Wang who was practicing the Dharma on the altar suddenly howled: "Fabi, break the enemy!" ”

As soon as the words fell, the strange egg who was writhing on the side suddenly slipped and fell, and rolled to the side, almost rolling off the high base, the strange chicken hurriedly went to pull, and after struggling, the strange egg finally stood up.

Such a funny scene once again swept away the tense atmosphere in the city, and Xiyang Wang Yuwen Wen coughed dryly when he saw this, and he was confident.

Not far away, in a bunker at the head of the city, Zhang Yu, the lieutenant of the palace, sneakily turned in, and several people inside were ready, looking at the rising water outside the city through the observation window.

On the surface of the water, many floating objects suddenly appeared, each of which was similar in appearance, but the color was slightly different.

Each floating object is a special thunderbolt, codenamed "anchor thunder", which is pre-arranged outside the city and buried on the surface.

The anchor mine is detonated by electricity, and the prevention is that an enemy ship is approaching the city wall to engage in "rumbling" by taking advantage of the heavy water, and in the bunkers on the head of the city, there are as many as 30 people controlling these anchor mines.

One person, one thunder, the special line detonates, and it will definitely not look away!

Zhang Yu looked at the water through the small window, and asked a little nervously: "How, won't you be confused?" ”

"Chief, absolutely not!"

"Chief, those anchor mines are connected to each other by ropes, as long as the ship passes through the middle, it will inevitably drive the anchor mines to hang on both sides, and then the switch will be closed, and none of them will be able to run away!"

"You save some money... There's not a lot of gunpowder in the city, and next time I won't be able to make up so many anchor mines, so I can save it..."

Zhang Yu chattered that he was not picking the door, but because the "railgun" consumed gunpowder was too exaggerated, and the "anchor mine" was not far behind, in order to ensure the long-term defense of the city, they had to save some gunpowder.

Although Anzhou tried its best to transport gunpowder before, the stock prepared in the city was still insufficient, and these anchor mines, at the same time, also shouldered the heavy responsibility of "mines", basically using one less one.

However, no one had time to pay attention to him, and they all stared at the enemy warships approaching on the water.

Outside, the Netherworld Master looked at the strange eggs and strange chickens on the altar that kept throwing motions, and really wanted to rush up and tear them off, but he couldn't do this, so he could only silently pick up his bow and arrows, and prepare to release arrows at the enemy warships approaching the city.

A warship rushed in front of it, only a hundred paces away from the city, and just as the Yin Shi Master bent his bow and arrows, the starboard side of the ship suddenly exploded, and a column of water rose into the sky.

The sudden explosion caused the ship to tilt quickly, and then sink into the water, and the Netherworld Master was stunned as if he had seen a ghost, and it didn't take long. Another enemy warship heading for the city was sunk by an inexplicable explosion in the water.

The Yin World Master looked at the altar blankly, the strange eggs and the strange chickens were still doing throwing movements, he couldn't believe what he saw with his own eyes, and there was only one thought in his heart: This is impossible!
