Early morning.

Yang Zhao was ready to flood Xiapi, and ordered Pan Feng to lead his troops to move away from all the villages near Xiapi, and those crops were gone, and they would bear all the losses caused during the flooding.

The villagers were originally worried, but after receiving Yang Zhao's promise, they had to move away because of the rumors of Yang Zhao's benevolence and righteousness during this time, coupled with the fact that the army came to drive them away.

The people were moved away and placed in the people of the Elk family.

Yang Zhao ordered the camp to be stationed at a high place.

Tao Qian and the others saw that Yang Zhao not only did not attack the city, but also carried out a series of incomprehensible operations, and they couldn't help but be full of doubts.

"Could it be that Yang Zhao is ready to retreat?"

Cao Bao said puzzled.

Zang Ba shook his head and said: "Yang Zhao moved all the people near Xiapi, this is not like a retreat, I am afraid that there is another purpose, it is not so simple." ”

But they couldn't understand Yang Zhao's approach, and wanted to send someone out of the city to investigate, but they didn't dare to do so, and they were very confused for a while.

"No matter!"

Tao Qian really had no choice, so he ordered: "The four city walls, all strengthen their vigilance, arrange enough patrol soldiers, keep rotating day and night, keep an eye on the bottom of the city tower, do a good job of defense, don't give Yang Zhao a chance." ”

"Yes!"

They said in unison.

Trapped inside the city, there is not much that can be done, only by strengthening the vigilance and being careful can the enemy outside the city be unable to attack.

Outside the city.

After moving the camp to a higher place and ensuring that the people nearby had moved away, Yang Zhao led the team to the edge of Surabaya, inspected the river, and observed how to use it between Surabaya and the moat.

"Surabaya and the moat are connected, and the water of the moat mainly comes from Surabaya."

Jia Xu stood on the shore and analyzed: "As long as we dig a ditch from the moat and go straight to the bottom of Xiapi City, with the low-lying terrain over there, the water can pass through the ditch, and it is easy to flood Xiapi." ”

Guo Jia asked people to find a bamboo pole and insert it into Surabaya, test the depth of the water, and said: "The current flow rate in Surabaya is not very much, the water depth is insufficient, and the Xiapi City is low-lying, but the inflow of water is not enough, and it cannot achieve the flooding effect." ”

As soon as these words came out, Jia Xu was also silent.

It's a real nuisance.

"Fill in the low-lying land around Xiapi with mud, enclose the city in the earthen wall, dig a ditch, and soak Xiapi."

Yang Zhao thought for a while and said: "The downstream of Surabaya is also blocked, the water flow is intercepted, and all of it flows into the moat, so that the amount of water flowing in will be enough." ”

Guo Jia reminded: "If Surabaya is intercepted, the crops downstream have no water available and cannot be watered, what should I do? ”

After a while, it will be spring ploughing, if there is no water downstream to irrigate, this year's people, will have to starve, in fact, the water floods, even if the water flow is not intercepted, will also divert part of the flow of Surabaya, resulting in a decrease in the source of irrigation.

However, if the water flow is intercepted completely, the impact on irrigation will be greater.

"At first, all of them were intercepted, and when they were almost soaked, they could be released in half and let some of the river water flow downstream, so arrange it!" Yang Zhao pondered for a moment before giving a new order.

If you don't do this, it will be difficult to break down, and if you wait until it rains and then flood, you don't know when you will have to wait.

"Good!"

Guo Jia and Jia Xu thought for a moment, and they could only do this.

The soldiers of the barracks soon went to dig the earth.

Tens of thousands of troops started together, but the speed was still very fast, and they piled bags of dirt around the low-lying land where Xiapi was located, filling in the low-lying edges.

The project was carried out for several days, and a man-high earthen wall was formed near the depression.

After completing this project, Yang Zhao ordered that a canal be dug on the edge of the moat.

The series of operations outside the city made Tao Qian in the city puzzled, and once again led everyone to the city tower to look down, looking confused.

"What exactly does Yang Zhao want to do?"

Tao Qian frowned, constantly speculating.

They were all thinking that Yang Zhao must have some plan when he did this, but no one could guess what the plan was, so they felt uneasy and worried.

"Envoy, look over there!"

Zhao Yu suddenly pointed to the side of the moat.

Everyone looked back and saw that Yang Zhao's soldiers were digging a ditch, which had been dug for a certain distance, and the ditch extended in the direction of the city gate.

"Flooding!"

Sun Guan was surprised: "Yang Zhao must be flooded when he does this, go back and get ready!" ”

Once Yecheng is flooded, their food and other things may be soaked or washed away, and the family's clothing, daily necessities, and even firewood for cooking will be unusable.

In ancient times, buildings were basically only one floor, and after the water poured into the city, they may not even have a place to live.

If there is a lot of stagnant water, it is easy to become dirty, which can breed diseases.

They instantly thought of all kinds of possibilities, and couldn't help but be shocked, thinking that Yang Zhao's approach was very vicious, so they hurriedly ran back to prepare, how many things could be saved, how much could be saved.

"Quickly send the order down, so that all the people in the city, ready to be flooded, climb to the roof!" Tao Qian said anxiously.

The city soon became busy.

The people in the city were trapped, and they were already dissatisfied, and suddenly got the news that Yang Zhao was going to flood Pi, and there were more people in a panic, resisting the joy of Yang Zhao's strong attack, and the smoke disappeared, replaced by all kinds of grievances.

Yang Zhao didn't know what the people in the city were doing.

But their practice of drowning down Pi should be guessed by Tao Qian and others, and it will probably cause panic, and the more panicked, the better.

"My lord, the soil used to block Surabaya has been prepared."

Jia Xu came back and reported: "The canal will probably be dug tomorrow!" ”

Yang Zhao said: "Wait one more night, and start tomorrow." ”

They were not in a hurry, and after speaking, they looked up at the city tower, and they had the chance of victory.

Time flies.

Early the next morning.

The soldiers came to report, and all the digging was completed.

"Stop the flow!" Yang Zhao shouted.

The soldiers threw sacks full of dirt into their designated positions, and as more and more things were filled, the flow was quickly stopped, and the flow of Surabaya began to rise, leaving only a trickle downstream.

"Dig up!"

Yang Zhao said again.

A soldier dug through the embankment of the moat.

Whoa......

There was a sound of water, and the blocked water rushed through the gap in the moat, into the dug canal, and rushed to the Xiapi city gate in front of it, and the water soon came to the city gate.

"Envoy, the water is coming!"

Sun Guan said loudly.

After a while, Tao Qian and others appeared on the city tower, looked down, and saw that the water began to accumulate near the city gate, and more and more, they were worried and at a loss.

Soak the city wall softly, and it will be easy for Yang Zhao to attack it.

"What should I do?"

Tao Qian asked anxiously again.

They didn't know what to do, so they could only stare at the city and see that nothing could be done.
