The Han army did not dare to leave the city, and could only watch it when facing the underground attack.

Due to the terrain, Bajun City is not as regular as the Central Plains City. When building the city wall, some places need to fill lakes and some places need to cut mountains, which leads to different degrees of solidity of the foundation. There are many students in the army who graduated from civil engineering. It is easy to judge the weakness of the city wall based on the terrain and the structure of the city wall. The tunnel is just built on the weak point, and it begins to collapse after several bombings.

Unfortunately, the tunnel was dug too deep, and the depth exceeded the foundation. The foundation of reinforced concrete was not so easy to explode. After the bombing, the Wei army poured it with water. After the water was poured, it was carried into an iron pot and poured gasoline to burn it. The reinforced concrete was easily deformed due to the alternating heat and heat. However, the tunnel was unable to be with people after such a tossing. It was full of the smell of gunpowder smoke after the explosion and the pungent smell of gasoline combustion. After staying for a long time, it was life-threatening.

The Wei army did not give up and rushed in with a wet mask. He filled the tunnel with explosives and then quickly withdrew, ignited the lead and bombed it again. The foundation finally could not stand the stimulation one after another. With a shocking sound, a section of the city wall more than three meters above the foundation broke directly and tilted inward, forming a slope leading to the city, and you could run in close proximity to the city wall.

Gao Shun and Chen Xiaozi stood in the distance and watched the city wall fall with their own eyes. Chen Xiaozi said excitedly: "It's God's helping me. If the city wall falls outward, we will feel a pity. Governor, do you want me to lead someone to charge?"

Gao Shun shook his head and refused, "The city is the main battlefield. If you are not prepared for it, don't go in easily, find the land and continue to blow up."

Chen Xiaozi asked in confusion: "Why?"

Gao Shun smiled and said, "The city wall has fallen. According to common sense, we will definitely rush in immediately. The defenders in the city must be ready for street fighting. Isn't it just right when entering now? Isn't it the Han army's wishes? I'm not as good as his wishes. Let them punch the cotton and go to the city. If the city wall falls, our army can enter the city at any time. Naturally, we have to choose their unexpected time to start. The timing is very important. Let's ask General Huang how the water storage is and when can he destroy the dike?"

Although there has not been heavy rain in recent days, the flow of the Yangtze River has not stopped. It is still persistently moving from up to downstream. It is blocked by Huang Zhong and accumulated more and more water. After receiving the order, Huang Zhong decisively blows up the embankment and is blocked by the flood that has been blocked for four or five days and rushes down the river channel. Unfortunately, it is not very harmful to the city.

The Bajun city was built on the hillside, and the terrain was high. Huo Jun was not a fool. Seeing the Yangtze River flowing slowly, he guessed the Wei army's plan and moved the personnel and supplies to a high place in advance, effectively avoiding the flood.

If one plan fails to succeed, the Wei army will naturally have a backhand. The flood rushed through the city and was blocked by the downstream embankment.

In order to prevent the flood from breaking through the embankment, Huang Zhong built three embankments downstream. The flood broke through the first embankment and stopped. After the flood, the Wei army in the downstream continued to deepen and thicken the embankment. The blocked water flow had nowhere to go, so he could only gather on both sides of the farmland and the city. As time went by, the water level in the city increased at a speed visible to the naked eye. As long as the downstream was well blocked, it was probably only a matter of time before the flood flooded the highest building in the city.

Gao Shun had no intention of waiting. As early as when the embankment was built and stored, he ordered people to build many rafts and prepare to attack the city.

The height of the city wall of Bajun is roughly the same, but the altitude is different. This side of Huanjiang is lower, and the altitude of the other side is relatively high. Standing on the wall of Huanjiang, you need to look up in the city. After the flood broke out, the city was flooded. Gao Shun personally led his army to take a raft and swam into the city from the wall of Huanjiang, and ordered the army to scatter the commanding heights such as the roof of the building and the mountain.
