I am the Crown Prince of the Three Kingdoms

Use sacks filled with soil as the first layer of protection, hay, tarpaulins, and mud as the second layer of protection, and finally, sacks filled with soil as the third layer of protection.

This is another strategy that Cao Cao came up with.

The cities of the Han Dynasty were all hard soil structures.Not only is it strong, but it is also watertight.What's more, the walls of Jiyin City are stronger.

Naturally, it is waterproof, but the weak point is the four city gates.

But now, Cao Cao wants to block the city gate, making the city drier.In other words, it is a stubborn resistance.

"In this way, it can last for a day or two. If you can delay the time, just delay the time."

Behind the gate of the northern city, Cao Cao stood in the rain, watching the soldiers working hard, thinking to himself.

"Your Majesty, the ship has been built."

At this moment, Dong Zhao came on horseback, arrived behind Cao Cao, and saluted.

But it turned out that Cao Cao also thought of the way out and ordered the building of ships to break through.For this reason, Dong Zhao demolished many mansions and mansions, and found a lot of wood.

In the end, what was made was just a small boat.

However, at least it is a way out.

"There is also a back road." Cao Cao said with a rare smile.

……

In the camp of the Han army, Liu Feng was doing almost the same thing as Cao Cao, preparing for the coming flood.

However, his preparation was different.

Liu Feng ordered to raise the foundation of the Han army camp.

Because Liu Feng had already piled up many warships in the Yellow River, as long as the flood was raging, those warships could sail in here, and then take advantage of the momentum to attack Jiyin.

And what Liu Feng needs to do is to raise the foundation and wait for the warship to sail in.

"It's about to start." Liu Feng led dozens of soldiers to patrol the camp, watching the soldiers pick up soil and stones to raise the foundation, and then he glanced at Jiyin City and said.

The first thousand 620 chapters and seven dams built

The Han army, Cao Wei, and Liu Bei's joint army are all making their own preparations.

The Han army is advancing, while the combined army of Cao Wei and Liu Bei is retreating.Both parties have put everything together for their respective interests.

Do your best.

In such a situation, time passed day after day.Soon, it will be half a month.And at this time, the rainy weather, more.

The rainwater is more abundant, and the water of the Yellow River has skyrocketed.

However, part of the Yellow River was blocked, and part of the soaring water of the Yellow River went downstream along the unfinished dam.

The other part entered Jiyin along with the water channel dug out by Liu Feng.

Now, outside Jiyin City, the water has spread to a depth of about one meter.

It can be said that the flooding of Jiyin City has been completed.But this is far from enough, because it is not enough for big ships to enter this water area.

The water needs to be deeper.

"Boom, boom."

On this day, the sky was covered with dark clouds, and streaks of lightning pierced the sky, making loud roaring noises.

"Hoohoohoo."

Thunder and lightning roared in the sky, and there was also a strong wind on the ground.The strong wind came from the northwest, and it was extremely powerful.

Wherever it passed, the wind howled, sweeping everything.

"Wow wow wow."

Not only that, the land that was supposed to stretch as far as the eye could see had already turned into a swamp of water, and the water was full of waves, and the sound was loud.

At this moment, the Han army camp is considered safe.

Before the flood started, Liu Feng had already raised the foundation.The current water potential is not enough to threaten the camp.However, the wind in the sky is causing headaches.

Many tents have already been overturned by the strong wind. At present, the generals are leading the soldiers to repair the tents.

"Boom, boom."

"Hoohoohoo."

"Wow wow wow."

At this moment, Liu Feng stood in the gust of wind, thunder flashed above his head, he personally felt the gust of wind sweeping through him, and he heard the sound of water splashing in his ears.

At this moment, Liu Feng was almost unable to stand firmly, and was deeply in awe of the power of this world.

"Cao Mengde, now, you are alone using the power of heaven and earth to destroy Yanzhou. You are proud enough." Liu Feng looked in the direction of Jiyin City and opened his mouth.

As soon as I opened my mouth, rainwater poured in, which was very uncomfortable.

Liu Feng had no choice but to turn over and return to the big tent of the Chinese army.

The big account of the Chinese army has been deformed.Because there are many ropes tied to it, and these ropes are fixed by wooden stakes, firmly suppressing the entire Chinese army tent.

The whole is naturally deformed.

However, the interior remains unchanged, still spacious.

Entering the tent of the Chinese army, Liu Feng saw Jia Xu and Liu Ye sitting upright, with very peaceful expressions on their faces.

At this moment, Liu Feng somewhat admired these two people.

Before the battle, his mind was agitated, but these two were old gods.

"General, order the dam to be completed and the water potential to be raised even higher. If this continues, the dam may collapse."

As soon as Liu Feng entered the tent of the Chinese army, Liu Ye spoke up.

"Well, it would be terrible if it was washed away." Liu Feng nodded when he heard the words. There is still a gap in the middle of the embankment, so we have to guard against it.

Thinking about it, Liu Feng ordered: "Order, complete the dam."

"Promise." Liu Ye promised, and turned around to give the order.
