After Zhuge Liang borrowed the arrow from the straw boat, he also put forward a battle plan to attack Cao Cao's flood and drought camp with Zhou Yu. At this moment, the brothers Cai He and Cai Zhong, Jingzhou generals who surrendered to Cao Cao, were sent to Zhou Yu's camp by Cao Cao and pretended to surrender. Zhou Yu, whose heart is like a mirror, played dumb again, playing along, and deliberately took two talents. One night, while Zhou Yu was meditating in the tent, Huang Gai sneaked into the tent to see him, and put forward a battle plan to burn Cao Jun. Zhou Yu told Huang Gai that he was going to use Cai Zhong and Cai He to cheat Cao Cao. And said: to let Cao Cao fall into the scam, someone has to suffer a little bit. Huang Gai immediately said: In order to repay Sun Shi Hou Si and Jiangdong's career, he was willing to be severely punished before surrendering to Cao Cao. The next day, Zhou Yu called the generals into the account and ordered them to receive food and grass for three months and prepare for Cao separately. Huang Gai interrupted Zhou Yu's conversation and said first, "Don't say three months, even spending 30 months on food and grass won't help." If Cao can beat this month, that would be great; If you can't beat him within a month, you might as well surrender as Zhang Zibu thinks. "Zhou Yuwen flew into a rage after hearing this surrender argument that ruined his prestige, encouraged the ambitions of others and shaken the morale of the army. He ordered Huang Gai to be pushed out of the account and beheaded. Huang Gai does not show weakness. He's a veteran of Jiangdong, seniority, and doesn't even care about Zhou Yu. This made Zhou Yu even more angry, and he wanted to make a decision as soon as possible. The escalation and intensification of the contradiction between Zhou and Huang made the generals quietly uneasy. General Gan Ning pleaded for Huang Gai on the grounds that he was a veteran of Wu Dong and was beaten by a disorderly stick. When all the civil and military officials saw that the viceroy was burned to death and veteran Huang Gai died in front of him, they knelt down together and begged for mercy for Huang Gai. For everyone's sake, Zhou Yusong let go and changed his decision to retype the 100 spinal staff immediately. The civil servants still felt that the stick was too heavy and begged Zhou Yu to raise his hand. Zhou Yu refused to give in this time. He overturned the table, dismissed all the officials and ordered the staff to go. The soldiers who carried out the case overturned the yellow cover, stripped off their clothes and severely hit 50 crutches. When the officials saw it, they fought for exemption. Zhou Yu hated it and returned it to the account. Zhou Yu and Huang Gai's double spring insurance almost fooled all civil and military officials. Only one person knew that he didn't say anything and stood by. He is Zhuge Liang. Huang Gai was badly beaten by these 50 sticks. He was raw and bloody, and fainted several times in a row. When other generals came to visit, Huang Gai kept silent and just sighed. There seem to be many skeletons in the closet. When his close friend Kan Ze came to see a doctor with suspicion, Huang Gai told the truth and asked Kan Ze, who is famous for his loyalty and courage, to sneak into Cao Ying and submit a fake surrender for him. Cao Cao, a wily man, was skeptical about Kan Ze and The False Surrender. But Kan Ze is by no means an idle person. He was courageous and eloquent, and finally persuaded Cao Cao. At this moment, Cai Zhong and Cai He, who had already infiltrated Zhou Yu's account, also sent someone to send Zhou Yu's anger stick and Huang Gai's tip-off. After Kan Ze left Cao Cao and went back, he brought a secret message to Cao Cao, further stipulating the code and logo of Huang Gai's contacts. During this period, Cai He and Cai Zhong also secretly delivered messages to Cao Cao from the south bank of the Yangtze River. All this was done seamlessly, which made Cao Cao firmly believe in Huang Gai's "surrender". Cao Cao's navy is mostly composed of northerners, and it is not suitable for water life. Many people get seasick because of turbulence. In addition, although Zhou Yu and others have determined the battle plan of burning warships, Cao Cao's naval warships are all independent. If one ship catches fire, other ships can still leave quickly. In order to create more favorable conditions for the fire attack, Zhou Yu cleverly let Pang Tong sneak into Cao Ying, and proposed a "serial plan" to Cao Cao to tie the warships together. In this way, Cao Cao's warships, whether in groups of 30 or 50, were all connected with iron locks, and wooden boards were laid on the ships to let the foot soldiers and horses on the ground. The problem of seasickness has been solved, and not only the foot soldiers applauded it, but even Cao Cao, who has experienced many battles and is well versed in the art of war, thinks that he can do his best in the face of the ship array as stable as Mount Tai. In the 13th year of Jian 'an (2008), on November 20th, Sun and Liu joined forces to prepare and arrange before the war. Zhuge Liang set up an altar to worship the wind for three days. It's nearly midnight at night, and sure enough, the southeast wind is getting stronger and stronger. Huang Gai also filled the prepared 20 big ships with reed dry wood, poured fish oil, sprinkled sulfur and mirabilite for ignition, and then covered them with green cloth and oilcloth. The bow of the boat was also nailed with big nails, and the contact sign "Qinglong Tooth Flag" was erected on the boat. Behind every big ship, there is a small boat tied with convenient movement. Huang Gai also sent a pawn to hold a book and agreed with Cao Cao to come down that night. Zhou Yu also arranged for ships to meet Huang Gai and the follow-up teams to attack. Cao Cao was in Jiangbei, waiting for news with other generals in Dazhai, when Huang Gai sent a secret message. The letter said: due to Zhou Yu's tight defense, Huang Gai had no intention of getting out at the moment. By chance, the Poyang Lake grain fleet arrived in the village. Zhou Yu ordered Huang Gai to patrol and gave him a chance to leave the camp. So, it is scheduled to come down at two o'clock that night, and the fleet with Qinglong Tooth Flag is the grain ship that came down. When Cao Cao saw this book, he was overjoyed and went to the boat in Shuizhai with other generals, waiting for the arrival of Huang Gai. On the flag of Huang Gai, the words "Pioneer Huang Gai" are written. He commanded the fake surrendered fleet and made rapid progress to the north shore while the southeast wind roared. Cao Cao was very happy to see Huang Gai's fleet coming far away, and thought it was God's blessing for his success. However, Cao Cao's subordinate Cheng Yu saw the flaw. He thought that a ship full of rations would not be so fast, so I'm afraid it was cheating. Hearing this, Cao Cao immediately sent a general to sail the boat and ordered Huang Gai to anchor in the middle of the river and not to go near the water village. But it's too late. At this time, the fake surrender fleet was only two miles away from Cao Jun's water village. As soon as he waved his sword, the ships in front set fire together. Each ship's firewood and fish oil burn immediately, and the fire rides the wind, and the wind helps the fire. The ship rushed into Cao Cao's water village like an arrow. At one time, all the warships in Cao Jun were on fire. Because the ships were chained together, the water village suddenly became a sea of fire. The fire quickly spread to Cao Daying on the north shore. In an emergency, Cao Cao, escorted by more than a dozen people such as Zhang Liao, changed ship and fled to the north shore. Sun and Liu all advanced at the same time, and Cao Jun was drowned in the fire and killed by an arrow. Cao Cao himself escaped. Zhou Yu and Huang Gai's "bitter plan" and "fake surrender plan" have achieved outstanding results so far, which is one of the important strategies for Sun Liu's allied forces to win the Chibi War.
