In the north of Yecheng, there are three mounds not far apart.

This terrain is much higher than Yecheng, and it is not far from Yecheng.

At this time, these three mounds have been surrounded by Dahua.

Between these three mounds, a huge reservoir is formed.

At the same time, Dahua sent soldiers to transport pumping water from the water to the reservoir formed by the three mounds.

There are hundreds of pumping machines operating at the same time, and the water in Zhangshui flows quickly into the reservoir.

Later, the water in Zhangshui was a little insufficient.

Lü Busuo ordered the soldiers to block the Zhangshui, so that almost the entire Zhangshui flowed to the reservoir and stored water in the reservoir.

In this case, it will only take about three to five days to fill the entire reservoir with water.

The storage capacity of this large reservoir is estimated to reach tens or even hundreds of millions of cubic meters of water.

This water is poured into Yecheng at once, and it can definitely flood Yecheng in an instant.

When the time comes, will the large amount of explosives planted by Cao Cao still be able to detonate after encountering water?

Well, well, actually, if they react fast enough, they can still detonate.

However, now the initiative to detonate these explosives has actually been in the hands of Cao Weiren.

They can detonate at any time.

Even if Dahua adopts the means of besieging but not attacking, even if they are besieged for a year or two, they can choose to detonate explosives at the last moment.

This point is beyond Dahua's control.

And now that Lu Bu has adopted the means of water attack, he can stop Cao Wei from doing this to the greatest extent.

Although doing so may cause deaths and injuries to the people in Yecheng, Lu Bu can't care so much.

You know, if they really besiege Yecheng for a year or two, I'm afraid that the people of Yecheng will die more at that time.

In this case, it is better to have a long pain than a short pain, and it is better to gamble once.

If you bet right, you will be able to successfully win Yecheng.

The wrong bet just made it happen a little bit earlier.

Regarding what Dahua was doing, Cao Wei's personnel were not aware of it at all.

They would never have dreamed that Dahua would make a pumping machine.

At this time, even Zhuge Liang, Pang Tong, Guo Jia and other major military divisions, as well as countless soldiers in Dahua, were stunned by the pump.

Well, well, in fact, the pumping machine, in terms of construction, manufacturing difficulty, and so on, cannot be compared with tanks, artillery, trucks, etc.

Even if it is presumably far from a power station, it is too far away.

But the most important thing is that they have never seen a pump before.

It never occurred to them that water could really flow to high places.

Not only can it be streamed, but it is also fast to be a thief.

All this once again subverted their imagination.

It's really incredible, how did the emperor make so many unbelievable instruments?

Although they knew that this must not have been made by the emperor.

But there is no need to ask, it must be the emperor's idea.

Now it's really good to be able to bring Zhangshui to a high place.

When the time comes, the water of the entire reservoir will pour down, after all, it will be able to flood Yecheng.

The day when Yecheng City is broken is just around the corner.

In the past few days, Dahua's soldiers have almost begun to go to the reservoir in batches to watch such a spectacular scene.

The scene is indeed extremely spectacular.

Hundreds of pumping machines pump water from Zhangshui into the reservoir day and night.

More than 100 pipes pour water into the reservoir day and night.

The water in the reservoir is slowly rising.

Well, this slowness is relative.

It can only be said that for a period of time, the naked eye could not distinguish it.

But as long as an hour, no, half an hour, or even half an hour is smaller, you can clearly see the increase in the water level.

It's the first time they've seen this kind of scene in their lives, and it's really insightful.

After five days in a row, the entire reservoir was finally filled with water.

It's not completely full, but the place they fenced with earth has begun to loosen.

If the water continues to be impounded, there is a high probability that these places will collapse.

Therefore, Lu Bu stopped the operation of continuing to store water into the reservoir.

This water is enough.

In the evening, in the direction of Yecheng, a large canal was built, facing the gate of Yecheng.

All around Yecheng were surrounded by mounds of earth.

It can be said that before the entire Yecheng is submerged, the water will not be able to run if it wants to.

At ten o'clock in the middle of the night, Lu Bu gave an order, and they directly detonated the bomb.

This bomb was planted in advance.

The location is just below the location opposite Yecheng, where an explosion will cause the mound to collapse and the water in the reservoir to pour down.

Sure enough, with the explosion, the lower mound was suddenly blown out of a large hollow.

The mound above began to collapse downward, and soon the mound was lower than the water level.

Then, the water in the reservoir began to pour downward.

At first, the current was not large, but the mound below began to be washed away rapidly.

The current began to grow bigger and bigger, and finally formed a terrifying pouring situation.

The water rushed to the walls and gates of Yecheng, and then spread along the gaps in the gates to Yecheng.

Of course, these crevices are too small to flow as much water as they can.

Then the water rushed down and began to flow down the city walls in all directions.

The four sides have been surrounded by mounds of earth, and the water has begun to flood the walls of Yecheng, and the water level is getting higher and higher.

The water began to seep into the city along the gates on all sides.

The water level is getting higher and higher, and when the water level is halfway to the city wall, the city wall begins to be quickly soaked with water, and some of the walls that have been in disrepair for a long time have cracks.

Gradually, these gaps grew larger and larger, and small sections of the walls began to collapse.

And as a small opening collapses, this small opening will grow larger and larger, eventually causing the collapse of a section of the city wall.

Immediately after, the water surged into Yecheng.

The soldiers defending the city were all frightened by the raging water.

Fast! It's so fast!

From the first time they saw the water, in just a few blinks of an eye, the water level began to rise higher and higher, and then the walls began to crumble.

By the time he reacted, shouted loudly quickly, and went to report the news, the water level in Yecheng had already submerged his shoes.

When he shouted all the way and ran to Cao Cao's residence, the water level was up to his knees.

Can you believe this?

"Your Majesty, it's not good! Oh no! It's a big flood! ”

In the past few days, Cao Cao's condition has been not good, he is physically and mentally exhausted, and he is haggard.

It hadn't been long since I fell asleep when I was woken up with an angry face.
