However, it was said that Cao Cao did not give up immediately after Liu Bei temporarily escaped. He continued to pursue Liu Bei along the river, and threw some bamboo slips into the Yangtze River and went down the river, claiming that his 800,000 army went south to try to win the hearts and minds of the people east of the Yangtze River. As a result, Cao Cao encountered a sniper attack by the Sun and Liu coalition forces at Sanjiangkou, losing many men and horses, and had no choice but to retreat. Cao Cao was not too angry about this, because Cao Cao himself knew very well that his soldiers were all northerners, and Cao Cao himself was not good at water warfare. This time, I didn't expect that Sun Quan's son would dare to resist him directly. He knew himself but didn't know the enemy, so there was nothing surprising about his defeat. Cao Cao has never been a person who cannot realize his mistakes. At this time, Cao Cao fully admitted that he might not be Jiangdong's opponent in the current water war. However, in this battle, Cao Cao has at least felt the attitude of the Sun family in Jiangdong. Sun Quan is unwilling to surrender, and plans to fight Cao Cao to the death! If you want to fight, then fight. Who was Cao Cao afraid of? ! When Liu Biao was still here, Cao Cao didn't pay much attention to Jiangdong. What's more, now that Liu Biao is gone, Jingzhou has surrendered! It is said that as early as a year ago, Cao Cao had already solved the Yuan brothers and stabilized the situation in the north. Before going south, Cao Cao had already built the Xuanwu Pond in Yecheng in advance to train his navy in order to prepare for going south to attack Jingzhou and Jiangdong. But now, Jingzhou has surrendered, with an outstanding naval warfare general like Cai Mao, and Jingzhou's original elite navy, Cao Cao has the confidence not to take Jiangdong seriously! So, Cao Cao built a water stronghold in Chibi, with Cai Mao and Zhang Yun as the commanders of the water army. He ordered Qing and Xu troops in the middle and Jingzhou army outside. They trained and practiced every day and waited for the day when they could be used. Cai Mao and Cai Mao have been familiar with water battles for a long time, and they really have two skills. Moreover, having recently surrendered to Cao Cao, Cai Mao and the others must have wanted to perform well in front of Cao Cao, hoping to be reused by Cao Cao. Cai Mao divided 24 water gates along the river. A large boat is placed outside as a city wall, and a small boat is placed inside to allow access. In the evening, lights are lit, making the water in the heart of the sky turn red. The dry village is more than three hundred miles away, and there are endless fireworks. This kind of formation is no exaggeration. No less than the Eight Gate Golden Lock Formation on the ground. Of course, without Cao Cao's huge financial, material and human support, Cai Hao would not have been able to do it easily. But now that it has been laid out, it can definitely achieve its intended effect. It is said that Zhou Yu personally came to spy on Cao Jun's water stronghold and saw this formation. He couldn't help but be shocked and said: "This is the secret of the navy army!" Immediately, Zhou Yu came up with the strategic direction that in order to defeat Cao Cao, he must first get rid of Cai Hao and Zhang Yun, the two commanders of the navy army of Cao Cao's army. ?¡ ?The so-called raising an army for a thousand days can only be spent in a moment. If you want to train soldiers who are not familiar with water warfare to fight in water warfare, it is just like training new recruits. It may even be more difficult than training new recruits because there is no actual combat drill. Therefore, not to mention training for a year, it will take at least half a year before Cao Cao can see his navy. It may still not be as elite as Jiangdong's navy, but with its absolute numerical advantage, it can still completely suppress its opponents. So, at this time, all we need is to stabilize and wait. at this time. The one who should really be worried is definitely not Cao Cao, but the Sun-Liu Alliance. However, as early as when Cao Cao defeated the Yuan family and went south to attack Liu Bei in the new field, it was already obvious that there was an overly radical and impetuous atmosphere in Cao Cao's camp. This year and a half. Not to mention whether Cao Cao can calm down, but some people below can't rest. Especially those who want to make meritorious deeds, are eager to make meritorious deeds, and think they can make meritorious deeds! Like. Jiang Qian. Nowadays, the only person Cao Cao is worried about is Jiangdong Zhou Yu, and Jiang Qian has been friends with Zhou Yu's classmates since he was a child. The relationship between Jiang Qian and Zhou Yu, well, Jiang Qian thinks to himself, is similar to that between Guo Jia and Xun Yu. Therefore, Jiang Gan took the initiative to ask for help, hoping to use his sharp tongue to go to Jiangdong to persuade Zhou Yu to surrender to Cao Cao. Although Cao Cao actually didn't have much hope for this, if Zhou Yu would surrender so easily, then he would no longer be Zhou Yu, and the Jiangdong Sun family would not dare to resist Cao so openly! But at this time, waiting is still waiting, and idleness is also idle. No matter how small the hope is, it is still hope. It is better than nothing. What if it really succeeds? Besides, with his subordinates so active, it would be hard for Cao Cao to dampen their enthusiasm, right? So, this is just a two-pronged approach, training continues as usual, while Jiang Gan crosses the river alone to meet Zhou Yu. I have to praise him, Jiang Gan is at least quite courageous. In short, Jiang Gan¡¯s action finally gave Zhou Yu an excellent opportunity to implement a counterintuitive plan! Afterwards, needless to say, Zhou Yu pretended to be drunk and let Jiang Gan see some things he "shouldn't see". So Jiang Gan fell into the trap and hurried back to the other side of the river to reveal Cai Mao and Zhang Yun's rebellion to Cao Cao. Later, Sun Quan asked Zhou Yu, "How can you be sure that Cao Cao will fall into the trap so easily?"  Zhou Yu smiled and replied, "It's not whether Cao Cao will fall into the trap, but whether Cao Cao is willing to fall into the trap!" "Yes, with Cao Cao's intelligence, would he fall into the trap so easily?" There were so many people driving a wedge between Cao Cao and Guo Jia back then. Have you ever seen Cao Cao take action against Guo Jia easily? Cao Cao was suspicious, but he couldn't kill such an important and key figure immediately. If you don't think it over carefully and do a thorough investigation, why don't you take it into custody first? Therefore, rather than saying that Cao Cao was deceived by Zhou Yu, it is better to say that Cao Cao deliberately pretended not to notice, deliberately pretended to be angry and killed, and was deliberately deceived by Zhou Yu. However, judging from the results, Cao Cao still fell into Zhou Yu's plan! I have to say, Cao Cao is arrogant! Yes, there were so many people driving a wedge between Cao Cao and Guo Jia. The reason why Cao Cao never took action against Guo Jia was because Cao Cao knew the importance of Guo Jia. And later, when Guo Jia was no longer so important, or in other words, when Cao Cao no longer thought Guo Jia was that important, there was no need for others to alienate him, and Cao Cao also took action against Guo Jia. The same is true now. Compared to Cai Mao's role, Cao Cao feels that Cai Mao may be a greater threat, especially because he is connected with Guo Jia. Therefore, for such a guy, it may be a little early to take action, but it is rare to have such a reasonable opportunity, why not take advantage of it? What? Don't you think Cao Cao's behavior seems contradictory? If Cao Cao didn't know the importance of Cai Mao, how could he hand over the position of Navy Commander to Cai Mao? How much time has passed now? Why did Cao Cao suddenly feel that Cai Mao was useless? Don¡¯t forget, there is a word ¡°learning¡± in this world! Is it possible that you, Cai Mao, are the only one in the world who can fight in water? Is this a natural talent that others cannot learn? During this period, Cao Cao actually asked his trusted generals to imitate, seek advice, and learn from Cai Mao's actions, arrangements, and training of soldiers. What Cao Cao wanted was for someone to succeed Cai Mao in the future and become the commander-in-chief of the navy! Since Cao Cao himself and most of his generals didn't know much about water warfare, although Zhou Yu's alienation plan came suddenly, Cao Cao thought he had learned it almost, but he didn't know that he had only learned its form but not its spirit. However, I don't know why, so Cao Cao decided that Cai Mao no longer played a big role, so Cao Cao was so reckless as to kill such an important navy general. (To be continued)
