Seeing that Ding Feng was dissatisfied, Jia Xu explained to him: "Zhou Yu's navy was well-trained and had a formation between offense and defense. If it weren't for the strong ship of our army that accidentally sank an enemy ship, it would have been defeated by them in a long time."

After hearing this, Ding Feng was stunned and said, "Formation? What Formation?"

Jia Xu smiled and said, "If I read it correctly, it should be the Liangyi Formation. The "Book of Changes" says: Yi has Tai Chi, which gives birth to two yin, two yin gives birth to four images, and four images give birth to eight trigrams. These two yin Formation comes from here. Zhou Yu's navy army cooperates with each other when facing the enemy. Seeing that our army is fighting each other. If it weren't for the strong ship, I'm afraid it would have been defeated at this time!"

While listening to Jia Xu's explanation, Ding Feng recalled the battle just now, and was only concerned with commanding the ship to hit the other side's ship. He didn't pay attention to the fighting style of Zhou Yu's navy. Now after hearing Jia Xu's explanation, he himself felt that this was the case.

After understanding the truth, Ding Feng dared not underestimate Jia Xu anymore. He said in his heart that he is worthy of being the one who is favored by the little military advisor, and he is indeed powerful. Thinking in his heart, he also became respectful. Ding Feng bowed to Jia Xu and said, "Mr. Wenhe, please teach me how to break the formation and defeat Zhou Yu's navy!"

Liu Bei nodded and said, "Well, Cheng Yuan's general intention this time is reasonable. As long as you put more effort into it, you will definitely defeat Sun Ce's navy. Wenhe is talking to him."

"It's the lord!" After saying that, Jia Xu turned his head and said to Ding Feng, "Actually, this is not the solution I came up with. It was Han Zicong who thought of it. Use multiple small boats to stick iron chains, then fill them with stones and sink them into the river. In this way, the small boat will be safe. When the big boat is drifting deeper, it will be caught by the iron chains and can only stay where you can slaughter!"

After hearing this, Ding Feng's eyes lit up and couldn't help but praise: "What a plan, so you just need to introduce the big ship opposite to us into the pre-sank land! Does Mr. Wenhe have a name for this trick?"

"You can't tell me, this move really has a name. It's called Tiexuanjiang!" Jia Xu replied with a smile.

"What an iron lock to block the river! Lord Wenhe, I will arrange someone to prepare now. I will definitely give Zhou Yu a big gift tomorrow!" Ding Feng said happily.

Liu Bei was also very happy and nodded, "Go and wait for you to break Sun Ce's navy. I will remember your first merit for you!"

"Don't worry, lord, I'll go here!" After hearing this, Ding Feng's blood boiled, he turned around and strode down to prepare to go. At this time, Zhang Fei, who was standing beside him, turned his head and said to Liu Bei: "Brother, when will it take to cross the Yangtze River? A certain snake spear is already hungry and thirsty! I wish I could fight at this time!"

After Zhang Fei finished speaking, Liu Bei had not spoken yet, Jia Xu said with a smile: "How about the third general, you go to the boat, and there will be a battle to board the boat tomorrow! Then you can show your skills when you fight in close combat!"

When Zhang Fei heard that he was about to get on the boat, he immediately stopped eating! He vomited so much that he would never forget it in his life. Now when he heard Jia Xu's words, Zhang Fei laughed dryly: "Brother, I suddenly remembered that the war horses were not fed today. You guys are chatting and I'll go out first!" After that, he ran away like a flying man without waiting for Liu Bei to speak.

Liu Bei looked at Zhang Fei's back and shook his head and said, "I really shouldn't have brought him here this time. It's because people from the north are not used to water combat!"

At this time, Jia Xu smiled and said, "Lord, this is not the case." Liu Bei was stunned and said, "Wenhe, how do you say this?"

Jia Xu continued to smile and said, "Before coming, Han Zicong found me specially and gave me two drawings in total, one of which was the iron lock blocking the river, and the other was this serial warship!" As Jia Xu said, he took out two pieces of paper from his arms and placed them on Liu Bei's desk. Liu Bei opened it and saw that it was indeed Han Fei's font, and then he looked carefully.

At this time, Jia Xu continued, "It's okay to block the river with iron locks, but Zicong specifically told me to use this series of warships with caution. Although this method can make the soldiers in the north praise the soldiers of the north, it may be difficult to escape if they encounter fire attacks and iron chains!"

After reading the picture at this time, Liu Bei said, "Zi Cong is such a talent! I have never heard of such a plan before, and I really don't know how he came up with it."

After hearing this, Jia Xu said laughing and crying: "Lord, it's not just you! We have never heard of such a plan! I want to congratulate you here. If you have Han Fei's assistance, why worry about the great cause not being successful!" Liu Bei laughed happily after hearing Jia Xu's words.

"Ah snee!" Han Fei sneezes and said, "Who is saying bad things about me behind my back!"

Cai Yan smiled and said, "Who else can it be? It's probably the lord and Mr. Jia!"

After hearing this, Han Fei nodded and said, "It should be them, but there are two pictures I gave, and Lao Jia's wisdom should be able to win the battle." Cai Yan smiled and said, "That's great. I don't want my father to be unable to see my child when he was born." After that, he touched his lower abdomen with his hands. Han Fei saw her movements and his mouth twitched, and said, "You're only over four months! Are you still early?"

At this time, the maid at the door came to report, and Hua Tuo came. Han Fei hurriedly got up and went out to greet him. Today, he specially found Hua Tuo to show his wife and concubine to his body.

When Han Fei came out, Hua Tuo had already walked into the yard. Han Fei smiled and said, "I'm sorry, the doctor!"

"Zi Cong, don't be polite. I'm not grateful for the successful completion of this medical school!" Hua Tuo was very happy recently. Seeing that the medical school was completed and used, he saw that more than 50 apprentices were studying in the medical school every day, which finally made Hua Tuo have a successor in the medical school! So Hua Tuo was very energetic recently. In addition to teaching classes, he would go into the library to study ancient books. These books were donated by Han Fei's father-in-law Cai Yong, and many of them were isolated books. So in addition to teaching classes, Hua Tuo wanted to organize these books into books and then copy them into books by the apprentices.

Seeing Hua Tuo so energetic, Han Fei was also happy for him. While speaking, the two of them let Hua Tuo into the back house. Hua Tuo took the pulse of Cai Yan and Mi Huan one after another, and then smiled and congratulated Han Fei on his face: "Zi Cong, your wife and concubine, are very strong, and the fetus in your belly are also very healthy. And I want to congratulate you, both of them are boys!"

"Really?" Han Fei said happily.

"Yes, I'm definitely inseparable! I've been practicing medicine for thirty years, and I still have this assurance!" Hua Tuo said with a smile. "Huh? Zicong, take your hand and let me take a look?"

Han Fei was stunned when he saw Hua Tuo talking suddenly and seriously, and then stretched out his left hand. Hua Tuo reached out to take Han Fei's pulse, and after a long time he asked, "Where have you been today and why are you poisoned?"
