Thousands of people break through are not simple things, especially the next three hundred miles of escape route. If you don’t plan thoroughly, it will be useless even if you rush out. Without food, people will starve to death. Without forage, especially essence, the horse will lose its physical strength or even die.

Cao Cao asked Xiahou Dun to prepare necessary food and supplies, and asked Cao Ren to lead the direct troops brought from Dongjun to reinforce Cao Hong. The east gate and the south gate were Qingshui, which was controlled by Jingzhou Navy, and the west gate was the main force led by Sun Ce. The direction of breaking through could only be the north gate. Originally, it planned to retreat to the inner city, but only considered giving up the north gate in order to shrink its troops. Now that we want to break through, the north gate cannot give up and must stick to it.

Cao Cao rushed to the west gate and saw Lou Gui turn around and look at the east gate of the inner city, with a pale face. However, Cao Cao unexpectedly saw another person - Wen Pin. He was surprised and didn't bother to talk to Lou Gui, so he rushed to Wen Pin and held his hand.

"Zhongye, is the injury healed?"

Wen Pin smiled, his face a little tired. He pulled his hand back quietly. "It's not a problem, thank you for your concern."

Cao Cao felt Wen Pin's indifference, sighed secretly, and patted Wen Pin's arm. "If I had known Zhong Ye had nothing to do, I wouldn't have to worry so much. Let me leave it to Zhong Ye?"

Wen Pin was very surprised. Cao Cao laughed, took the flag from Lou Gui's hand, stuffed it into Wen Pin's hand, and pulled Lou Gui to the side. Lou Gui was unhappy, but he did not dare to do anything, so he had to follow Cao Cao down the city wall and go outside the inner city gate. At this time, the dust that was hit by the first huge rock had gradually settled, revealing the broken courtyard wall and the collapsed house. Lou Gui felt his heart tightened, and his scalp was numb.

"Zi Bo, this is one of the two stone bullets that just shot in outside the city. You should have heard the sound at Ximen, right?"

Lou Gui was silent and nodded repeatedly, but couldn't speak.

Cao Cao smiled bitterly and said, "Zi Bo, I'm afraid Wancheng can't be defended anymore. I want to break through as soon as possible. Should you follow me or stay? If you follow me, hurry up and go back and say goodbye to your family. If you want to stay, I will hand over the inner city to you. I will make contributions to protecting the hostages. Yuan Gaolu should not make things difficult for you."

Lou Gui was shocked and stared at Cao Cao for a long time without saying anything. Yesterday he said it well and wanted to stand by waiting for help. Why did Cao Cao want to abandon the city and leave just after one day? He suddenly understood the intention of Cao Cao to take him to see the stone bullet and quickly weighed the pros and cons. Not to mention whether Cao Cao could succeed in breaking through, even if he succeeded, he could not get in touch with Yuan Shao. Instead of following him to take risks, it would be better to stay in Wancheng. He made contributions to the city, and with those hostages, Yuan Shu should not make things difficult for him, and maybe he would reward him heavily.

"My family is all here, I can't leave them."

Cao Cao sighed and reluctantly held Lou Gui's hand. "I originally wanted to dominate the world with Zibo, and the will of heaven will make people. Sun Ce was fierce, and Wancheng was lost again. Zibo, everyone has their own ambitions, so I won't force it. Don't worry, I will take it all in front of the leader, and I will never implicate Zibo and the wise men of Wancheng."

Lou Gui was ashamed. He wanted to change his mind several times and followed Cao Cao, but he swallowed it back when he was at his mouth. Cao Cao was a friend who could be made friends, but his strength was too weak to realize his wish.

Cao Cao handed over the inner city to Lou Gui, quietly adjusted the city defense. The army brought dry food for ten days and gathered at the north gate, ready to break through.

The battle at the North Gate suddenly became stalemate. Chen Yu fought hard for a day. Although he broke through the city gate, he failed to attack the city.

——

As night fell, Sun Ce and Zhou Yu changed defense and returned to the camp to rest.

Pang Tong had already arranged dinner, but Sun Ce did not eat immediately. He wanted to wait for Huang Chengyan and his daughter to have dinner together. Although the platform was higher than the walls of Wancheng, it was too far away. He could not see the situation in the city and did not know the attack effect of the giant stone thrower. He had to wait for Huang Chengyan to confirm.

While waiting, Cai Yong came. Sun Ce was surprised, but he still stood up to greet him. Cai Yong walked into the tent in a small way, smelled the fragrance of the rice, and sniffed. "I'm disturbing the general."

Sun Ce laughed. "Sir, aren't you just stepping in? Don't be polite, sit down and have something together later." As he said, he gave Cai Yong to the ceremonial seat on his left. Cai Yong was very satisfied, and after a few words of modesty, he entered the seat, stroked his beard, and said seriously: "I heard from Zhou Gongjin that you have discussed the way of heaven with Lu Jining?"

Sun Ce raised his eyebrows slightly. "Are you in Gongjin Camp just now?"

Cai Yong nodded. "I was idle and heard that Zhou Gongjin was quite good at music, so he played the piano with him and talked about music, and adjusted the tune of "The Suffering of the People". At a young age, he had such achievements, which is really attractive."

Sun Ce knew that Zhou Yu had high musical attainments, so it was no problem to be better than him. When he heard "Shanpo Sheep·Tongguan Reminiscence", Zhou Yu composed the song in just a few words. With his ability, it was not strange to discuss music with Cai Yong. It was just that the battle was about to be around, and Zhou Yu actually had such leisure and elegance, which was really beyond his expectations.

"What advice do you have?"

"You highly respect Zhang Pingzi, I guess what Huntian said?"

Sun Ce frowned. To be honest, he is not interested in discussing this issue now. First, he is not very interested in talking and quoting classics. He is not a match for Cai Yong - even Pang Shanmin was abused by Cai Yong, and he is even less able to do so. Second, he really has no time. He is now siegeing the city, and there may be accidents at any time. He doesn't sleep for two days and one night, so he dare not rest. He is not interested in sitting and talking about something irrelevant.

"It's barely true."

"Do you know what are the two theories in addition to Huntian's theory?"

Sun Ce suddenly thought of something. In addition to the Huntian theory, the universe model of ancient Chinese astronomy also includes Xuanye theory and Gaitian theory. Gaitian theory comes from the "Zhoufeng Suanjing", and Xuanye theory comes from Cai Yong himself. Compared with Huntian theory and Gaitian theory, the biggest feature of Xuanye theory is that it believes that the sun, moon and stars are not on the same celestial sphere, but are suspended in the qi, and there is no fixed celestial sphere, but infinite. To a certain extent, this is the most Taoist of the three theories and closest to later science.

However, the origin of Xuan Ye’s statement has never been clear, and even Cai Yong himself is very clear. The content is even simpler, unable to calculate, and cannot be compared with the other two theories.

Sun Ce tilted his head and looked at Cai Yong for a while. "Sir, since I talked about the way of heaven, I want to ask a question first, is it OK?"

Cai Yong nodded confidently.

Sun Ce's mouth raised a smirk. "Does the running rules of the sun, moon and stars be calculated?"

Cai Yong did not think. "Of course, otherwise what's the use of a calendar?"

Sun Ce glanced at Cai Yong sideways, smiling without saying a word. Cai Yong was stunned for a moment, suddenly understood what Sun Ce meant, and immediately said: "With man and nature are united, and the government orders are erratic, then God warns you, of course, these are not countable."
