Yelufeng's armor was also covered in blood. The original color of the bright armor could no longer be seen. He held a knife and ran while looking at the soldiers on the left and right. "Ouch." Yelufeng shouted. Everyone slipped out. It turned out that there was a puddle of water on the ground, which had frozen into ice. There was snow on the ice again. Yelufeng stepped on it and couldn't stand upright. His whole body was knocked out and he slipped out. This slip and fall More than two feet away. The collision made him dizzy. "Sir." Several colleagues around him turned around and called. Yelufeng got up dizzy. He shouted: "Sir, please don't worry about me. It's important to take back the city gate." Several generals gritted their teeth. They waved their hands and ran forward with their men and horses. Yelufeng asked the two soldiers to pull him up. He looked around. He didn't know where his sword had been thrown. There were puddles on the ground. The snow is very thick. It is difficult to find. "Wait a minute." Just after running two steps, Yelufeng suddenly stopped. He slowly turned his head and stared straight at the place where he had just slipped. A strange light gradually appeared in his eyes. . Several Khitan generals finally arrived in time and charged forward. Their momentum was unstoppable. The morale of the Yan army, which had been struggling to support itself under the city gate, was greatly boosted. After desperate resistance, they actually pushed the Tang army's defense line back several feet. Like wolves and tigers, they charged into the enemy group. "Back off, back off." Yelufeng, who had rushed to the city wall, ordered his people to shout. The guard general and others at the bottom of the city heard the police and just took shelter under the city gate. There was a splash on the city. Something unknown poured down like heavy rain. The Tang army thought it was golden juice and dung soup. They hurriedly retreated to observe its movement, but it turned out to be boiling water. The water splashed on the body, and the burning pain was unbearable. Once it hit the ground, the heat was boiling. There was heavy snow on the ground. The water vapor filled the air again. For a moment, it was like a heavy fog. It even blocked the city gate. No one could see from inside or outside. Immediately afterwards, bundles of firewood were thrown under the city. Then hot water was poured on it. At the same time, Yelufeng ordered his men to stop saving arrows. The limited arrows of the city defenders all used this time to shoot and wound many Tang troops. Yelufeng used hot water originally to stop the enemy. He was also worried that the hot water should not freeze, but there was no solution to both problems. I was quite uneasy, but I didn't know that hot water freezes more easily than cold water. Yelufeng hit him crookedly. The pile of firewood got higher and higher. He poured hot water on it layer by layer. When the arrows fell from the city head, he stopped attacking the enemy troops below. When there was no other way, an ice wall had already stood in front of the city gate, firmly blocking the city gate. In the past, on the grassland, in order to resist the cold wind, the tribes used to freeze straw bales and water into walls. In winter, the tribesmen would Hiding in the lee of the wall, he waited until the spring flowers bloomed and the tribes migrated. The ice wall also automatically collapsed. This method of rapid city building had never occurred to him. But he never thought of using it on Beiping City. Just now he slipped and saw the thin film under his feet. The thin layer of ice. I suddenly thought of this. I didn't expect it to work. Duan Mingyu led the soldiers. They ran for several miles. The blood of these soldiers ran away. They were in high spirits. "The morale is high" but It was useless for them to come. In the confusion of heavy snow, the soldiers of the Tang army saw such a miracle. They felt that the Khitan army seemed to have help from heaven and was completely invincible. They couldn't help but feel depressed. Duan Mingyu had to return gloomily. Back to the big tent. Looking at the sand table, I felt a powerless feeling in my heart. At this time, Yang Zhaoniang suddenly ran in and said triumphantly, "Brother Mingyu, I have it." Duan Mingyu was shocked. "What. You have it. Which one?" You bastard did it." "What? Where did you think you were going? They said I have a way to break the city" A blush appeared on Yang Zhaoniang's pretty face. She whispered into Duan Mingyu's ear. "Is this possible?" Duan Mingyu said suspiciously. "How will you know if you don't try? There are 400,000 people. One bag of sand per person is enough to fill it up." Yang Zhaoniang replied confidently. "Okay then. Let's give it a try." Without further delay, Duan Mingyu immediately ordered each of the three armies to take a sack and fill it with a bag full of sand. The attack on the city on the second day would be of great use. The officers and soldiers of the three armies were all suspicious. When they attacked the city on the second day. Yelufeng found that the Tang army was obviously just bluffing. The attack was not that brutal. But he discovered a strange phenomenon. Each Tang army carried a large sack. It was actually filled with sand. These soldiers were supported by bows and crossbows. After approaching the base of the city wall, he opened the sack, dumped the killing soil on the base of the city wall, and left without hesitation. One bag of sand for each person. The Tang army totaled 400,000 people. At first, Yelufeng didn't realize the truth. In the end, it fell. When the pile of sand that came out reached half the height of the city wall, Yelufeng suddenly realized it. He couldn't help but feel a chill in his heart. Finally, in the evening, Duan Mingyu came to Yanjing City under the escort of his own soldiers. The walls of Yanjing City were still high. But the giant tigers in the sand outside the city wall are about to cover the city wall. They can climb up directly from the sand. The cavalry can leap to the top of the city with just a slight lift of their horseshoes. Duan Mingyu hugged a thin and handsome soldier beside him in surprise. After a kiss, "Zhao Niang, I love you to death." A faint blush suddenly appeared on the soldier's cheeks. The next day, Youzhou City was destroyed. The guard Yelufeng was defeated and committed suicide. Duan Mingyu stood at the top of Youzhou City. .I was so excited that I yelled."We have finally captured Youzhou City. Everyone can go home to celebrate the New Year." The soldiers below raised their swords and guns in unison. They couldn't help but shout in unison. "Go home.
