The conspiracy can only be hidden in the darkness. Once exposed to the sun, it will melt quickly like ice and snow. The same is true for the tunnel. If it is not discovered, it can receive miraculous effects from behind, and if it is discovered, it will be invalid.

Wei Jun quickly found gasoline, opened the bucket plug and directly in, and threw the torch down. The kerosene smoke was large, and it was ignited at a glance and infinite black smoke came out. Then he covered it with a wooden board. The black smoke could not be found and could only wander in the tunnel.

There were still many Han soldiers lurking in the tunnel. They wanted to take the opportunity to climb out, but now they were both fire and smoke, but they rushed over. If they didn't want to be smoked, they could only cover their mouths and noses and retreat helplessly.

Lu Xun waited at the entrance of the cave for about twenty minutes before saying, "It's almost done, go down and take a look."

The wooden board was unveiled, and a large amount of thick smoke came out on the spot. The Wei army in front of the smoked hole all coughed violently. After the thick smoke passed, he looked down and saw that the flames were still burning and he could not get out of nowhere.

Lu Xun changed his words and said, "Pour a few more barrels... Forget it, there is no need to waste kerosene, just pour concrete. If you block the tunnel, see how the Han army came up."

The city had sufficient material reserves. Before the Han army arrived, Zhang Liao ordered Hu to transfer a lot of cement, sand and stone, and it was easy to get some concrete out. However, this incident reminded Lu Xun and ordered the county magistrate Chen Zhang to patrol the city walls with the police, and report immediately once the tunnel entrance was found.

Time passed slowly, but the rain did not stop, but the night came quietly. The Han army, who had been attacking for a day, could not bear to take it, so they had to retreat helplessly.

The intensity of the siege during the day allowed Lu Xun to clearly see Zhou Yu's determination to break the city, so at night he did not dare to relax his vigilance and ordered people to strengthen inspections, especially the East City Wall, which had never been attacked since the war began.

As expected, at the third update, a team of Han soldiers climbed up along the city wall with ropes. They were discovered and rushed down by patrol soldiers in time. There was another wave at dawn. Fortunately, Lu Xun was prepared and did not cause any major losses.

The generals on both sides are smart people, and opportunistic methods are useless. If you want to break the city, you have to attack hard. After dawn, the siege began again. In order to relieve the pressure, Lu Xun had to order Shen Jie to go out to harass the city again. The same trick was repeated, and the fight was so lively.

Four days passed quickly, and Zhou Yu attacked day and night for four days. Many places in the city wall were bombed with gaps of varying sizes, but they could still hold on. The city wall could not support the soldiers in the city, and there were heavy casualties. In addition, they could not get a rest, so they were exhausted and could fall asleep after a trip to the ground.

This is not the most deadly thing. The most important thing is that there are not enough shells. In order to cope with the tide of the Han army, the guns and cannons had to be fully fired and operated overload. Although the barrels were cooled down due to rain, they could not withstand frequent use. Many of them had been damaged, and so were the barrels.

Compared with the Wei army, the Han army suffered greater casualties, and the city was covered with corpses. Zhou Yu was not allowed to stop the attack. The Han army attacking the city had to charge on the corpses of his companions. The battle situation was so tragic.

After not resting for several days, Lu Xun's eyes were covered with red bloodshots, and his hair was as disheveled as a savage walking out of the deep mountains. There was no trace of the beautiful young man who had a long time.

The war was urgent and Lu Xun was not the only one. Even the county magistrate Chen Zhang brought his sword to the city and tried his best. The two worked together to drive a team of Han troops climbing up the ladder. Chen Zhang leaned on the ground with a knife and said breathlessly: "Secretariat quickly find a way, so you won't last long."

Lu Xun smiled bitterly and said, "I have thought about all the ways I should think of, and I have no idea. Let's take one step at a time. At worst, I can sacrifice my life for the country."

Chen Zhang: "..." Did you give up treatment so quickly?

Thinking about it, the city's defenders are less than 8,000. Facing an enemy with more than ten times more than our own and well-equipped enemy troops, it is good to be able to hold on for five or six days. If you fail, you will be able to be virtuous. Since you can't defend it, you can simply die with the city to repay your kindness.

Lu Xun said in a cold tone: "If the order is sent down, once the city is broken, we immediately retreat into the city for street fighting. We have only one task now. If we drag it, we can buy more time for Governor Zhang. Then we will tell the people that if the city is broken, their only fate will be to be forced to move to Kushan by the Han army. If we don't want to leave our hometown, we will go to the city with weapons and resist the Han army with our soldiers. At this time, we should launch all the forces that can be activated."

He learned from Lu Ming who returned to him where Zhang Liao was going. Now he not only can't count on Zhang Liao for rescue, but also has to try his best to entangle the Han army and buy enough time for Zhang Liao. It's hard.

Chen Zhang clasped his fists and said, "Don't worry, the master will go and prepare now."

After saying that, he saw a soldier rushing over in the rain of bullets and praying: "Teacher, Ling Tong from the North City suddenly withdrew his troops and disappeared. The siege of the North City was lifted."

Chen Zhangxi said: "Is the news of the governor's attack on Shouchun coming back?"

Shouchun is the place where the Han army must rescue, and the news came back to Zhou Yu and would definitely run faster than the rabbit.

Lu Xun was not so optimistic, pointing at the Han army that was still charging under the city and said, "It's not so fast. The Han army in Beicheng retreated from Xicheng but did not retreat. What does it mean?"

Chen Zhang frowned and thought for a moment, exclaiming: "Is the Han army going to flood the city?"

Zhou Yu ordered people to divert the river a few days ago. Although the excavator was robbed, it could not stop him from drowning the city. Calculate the time and it was almost done.

"Go and go and have a look."

Lu Xun raised his foot and rushed to Beicheng. Chen Zhang hurriedly followed. When he arrived at Beicheng, he saw that the city was empty and even the bodies of the Han army could not be seen.

The empty eyes did not give Lu Xun much sense of security, but instead made his face even more serious because he knew what this scene meant.

Sure enough, after waiting for less than ten minutes, a huge wave rushed over, which was as shocked as a tsunami.

"Here's coming, the flood is coming..." The soldiers around him exclaimed and fearful, but Lu Xun ignored it and stared at the front.

The flood swept quickly with a rush of mountains and seas. It merged with the moat that had already skyrocketed, and smashed hard on the city wall like a giant's slap. The waves raised were as high as four or five feet high. The waves crossed the city wall and slapped on the top of the city. All the soldiers in the city were poured out to the hearts of the heart. They stood unsteadily and fell on the spot. The flood penetrated through their mouths and noses, and the choked people almost suffocated.

Fortunately, the water flowed to the lower part. After the flood hit the city, it quickly flowed into the city along the drainage ditches. Only then did the soldiers in the city get a chance to breathe.

Lu Xun stood up with a knife and coughed several times before saying, "The flood was the first wave, and it was smooth afterwards. Fortunately, the city wall was firm and blocked us."

The flood once again proved the quality of the city wall's project. Lu Xun sneered: "Mr. Chen, your water pump is in handy. Pumping water, it's a blessing to have a loss. The flood siege of the city may not be a bad thing for us. At least it can cause a considerable obstacle to the Han army's siege. By the way, who built this city, the contractor will introduce it to me."

Chen Zhang was speechless, when did you still think about this?

But as Lu Xun expected, the flood broke out more violently, and after the explosion, it calmed down. The flood that rushed behind did not cross the city wall anymore and was blocked outside the city. The city wall was flooded nearly two meters high, and the East City completely became a water city.
