Liu Heitai waved his hand, and in the deep ditch where he was standing, dozens of sergeants lifted up a large pile of firewood covered with kerosene and sulfur. When the torch was turned on, choking smoke suddenly rose. Ten sergeants with their mouths and noses covered tried their best to blow the air into the tunnel, and yellow poisonous smoke rolled in. Soon, the tunnel was filled with coughs and screams, and gradually, nothing could be heard. Liu Heitai touched his nose, shook his head, and murmured: "This is the most miserable way of death I have ever seen. Remember to die in the sun in the next life. Someone, please give me this hole after you finish the cigarette." Just fill it in, just fifty steps outside the city. There are dead people behind, and no one will dare to come in anymore. " Outside the south city, the corners of Li Shimin's mouth were twitching slightly, and the choking smoke was blowing on his resolute face. , at the tunnel mouths of five large holes around him, people with black bodies and tears streaming out of the underground cave kept coming out, crying and vomiting, and after coming out, they lay on the ground and vomited loudly. The billowing poisonous smoke came from The sounds of screams and coughs floated out from the entrance of these five large holes, stimulating everyone's soul. Everyone looked at Li Shimin with serious expressions and said nothing. Qin Qiong murmured: "It's so evil. Is Wang Laoxie really helped by gods and ghosts? Why, why does he know our authentic fighting methods?" Li Shimin closed his eyes and sighed. Tone: "We still underestimated Wang Shichong's strength. It was my fault. The soldiers were harmed. More than two thousand brothers in the five tunnels died because of me!" Yu Chigong's eyes widened and he said loudly: "King Qin , give me another 10,000 people, and I, Old Hei, will definitely rush to the city of Luoyang!" Li Shimin opened his eyes and shook his head expressionlessly: "It's useless, if we increase our troops, Wang Laoxie will also increase his troops! , Luoyang City is high and deep, and it cannot be captured by gathering people. General Luo has been fighting for so long and has not yet reached the top of Luoyang City. If we add more people and crowd together, we will only cause a lot of damage to the enemy. It doesn't help. Today, our carefully designed tunnel tactics were defeated by Wang Laoxie. There is no point in continuing the attack. With the order, the catapult hit the top of Luoyang City to cover the evacuation of the siege troops. " Yuchi Gong roared. He was full of unwillingness and anger: "No, I don't accept it, are you just going to retreat like this?" Li Shimin's eyes flashed coldly: "Don't fight because of anger. The fist you withdraw will be more powerful when you punch it out, boss Hei, I will give you a chance to rush to the top of Luoyang City, but not now! Send the order, withdraw your troops!" Luoyang, the top of Nancheng City, was full of cheering Huaqiang Army soldiers, and many civilians hugged each other excitedly, singing and singing. Jump, a large number of Huainan infantry are marching down the city in an orderly manner, while the civilian men on duty on the battlements are throwing the corpses of the Tang soldiers who died in the battle at the top of the city into the city, while carrying the corpses of their own soldiers to the city wall. Next, he took down the large and small stones scattered all over the city. The originally crowded city suddenly became much emptyer. Wang Shichong sat quietly on the maza. At this moment, he finally no longer had to dress up as a soldier. Dozens of shield-wielding guards were still guarding his side. His eyes were shining brightly as he looked at the Tang army retreating like a tide. , thoughtfully. Wang Renze smiled excitedly and said: "Commander, we have won. We have cracked all the Tang army's tactics. No matter whether it is a chariot or a tunnel, they can't shake our strong city of Luoyang, hahahahahaha. "Wang Shichong curled his lips and said calmly: "Have our losses been calculated?" Wei Zheng nodded: "The losses and gains in each city have been reported. In total, our four cities lost more than 3,200 today. Most of them were civilians and state and county soldiers who were temporarily assigned to defend the city. The Huainan soldiers and the Xiaoguo army lost more than 540 people. " Wang Shichong nodded: "How about the enemy killings?" Wei Zheng took a look. Holding the silk in his hand, he said: "I don't know how many Tang soldiers were killed in the tunnel. It is estimated that there were more than two thousand people. The total number of Tang soldiers killed and burned in each city was about fourteen to five thousand. More than half. It's here in our Nancheng. Lord, your judgment is correct. They are indeed attacking Nancheng today. If you hadn't been here personally, it would have been a bit dangerous." Wang Shichong sighed: "Li Shimin did not rush to attack Nancheng. This shows that. They still maintained their sanity. What am I most worried about next, Xuancheng, do you know?" At this point, Wang Shichong glanced at Wang Renze, who knew it well, nodded, and retreated with his guards. Far away, only Wang Shichong and Wei Zheng were left here. Wei Zheng had been thinking intently. After Wang Renze and others retreated, he said, "My lord is afraid that Li Shimin will not succeed in attacking the city. Is it possible to withdraw his troops back to Guanzhong?" Wang Shichong nodded: "Exactly, we have spent so much time. He worked so hard to pin Li Shimin to the gate of Luoyang City and ask him to move his main force to the south of the city, so that he could defeat him in one battle.??, if he really runs away, then all our efforts will be in vain. Even if we get the Central Plains, there will be nothing to be happy about. So, what can you do to make Li Shimin continue to see hope and stay and besiege him? " Wei Zheng curled his lips and said: "The current offensive and defensive battle in Luoyang is like a gamble. Both sides are increasing their bets. Li Tang won too quickly and smoothly. Today's siege is a major blow to them. Such a setback There may be two situations. One is that the generals are dissatisfied and request to continue to attack the city; the other is that the generals are frustrated and want to retreat back to Guanzhong. I expect that the current generals of Li and Tang still have some energy and feel that the capture of Luoyang is just around the corner, so they will continue to attack the city. Wang Shichong curled his lips and said seriously: "So, we can't let them be so desperate like today. We have to let them see that there is hope to conquer Luoyang." Today Li Shimin besieged Nancheng. Normally, the geographical conditions in Nancheng are not as good as those in the north, and Li Tang's main force is also in the north. But today Li Shimin wanted to make a sneak attack. Starting tomorrow, he should launch a force attack in Beicheng. " Wei Zheng nodded: "Exactly, then do we need to strengthen Beicheng's defense tomorrow? " Wang Shichong shook his head: "No, starting tomorrow, all militiamen will be used to defend Beicheng. Three thousand Huainan infantry will be left to maneuver below the city. If Tang soldiers go up to the city, they will go up to the city to counterattack. " Wei Zheng opened his eyes wide: "Isn't this too much? Can the Tang soldiers be suppressed when they come to the city? Wang Shichong's eyes flashed with green light: "Don't worry, three thousand elite soldiers are enough to defend the city. Two thousand elite soldiers are ambushed in the mezzanine layer and secret door inside the city wall. When the city is tight, they will go out to fight back and force the Tang soldiers back." Come back and let the Tang army's attack knock out some of the ballistas defending the city in Beicheng. If there is hope, they will keep fighting. I want them to fight for another ten days and a half, and another 30,000 to 50,000 people will die. At that time, I saw whether Li Shimin would retreat or not. "
