It is said that Zhuge Liang learned that Lu Su came to mourn from Jiangdong's report and Zhuge Jin's secret letter, and learned from Liu Qi that Jiangdong and Liu Biao had a grudge against his father.

The plan has been decided, so that people greet Lu Su, receive gifts, Liu Qi thanked him, and led Liu Bei and Zhuge Liang to meet.

Lu Su asked about Cao Cao, and Liu Bei pushed it to Zhuge Liang according to his words.

After talking, Lu Su invited Zhuge Liang to Jiangdong to meet Sun Quan and discuss a joint plan to break Cao.

Before leaving, Zhuge Liang arranged for Liu Qi to carefully survey the terrain of the counties along the Yangtze River according to the map of Jingzhou and draw a detailed map for later use; The secret order is that a shrewd soldier who is familiar with water nature drives a boat to the opposite shore and stops there, waits to deliver news back and forth, and then boards the boat with Lu Su and goes to Chaisang.

In front of Sun Quan's gathering of civil and military, Zhuge Liang's tongue fought against Confucianism, Lu Zijing was overcrowded, Sun Quan hesitated and retreated into the inner house.

Wu Guotai saw that Sun Quan was restless in sleep, so he asked: "What's in your heart, sleep and eat are wasted?" ”

Sun Quan said: "Today, Cao Cao is stationed in Jianghan, and he has an army of 830,000 and wants to go down to the south of the Yangtze River. Ask the civil and military, the literati want to surrender, and the warriors want to fight. If you want to fight, you are afraid of being outnumbered; If you want to surrender, your father and brother's inheritance will be put into others, and you can't bear it, so you hesitate. ”

Wu Guotai said: "Do you remember my sister's dying words? On her deathbed, the first sister said, 'Bo Fu said on his deathbed: ask Zhang Zhao if you don't decide on internal affairs, and ask Zhou Yu if you don't decide on foreign affairs'. Why don't you recall Zhou Yu and ask him today? ”

Sun Quan woke up like a dream, and immediately sent an envoy to Poyang to invite Zhou Yu to come to Chaisang to discuss matters.

It turned out that Zhou Yu was training sailors in Poyang Lake, and when he heard that Cao Cao was leading his army south, he rushed back to Chaisang in the starry night.

Sun Quan's envoy was not sent, Zhou Yu had arrived, saw Sun Quan, looked at Cao Cao's biography, and disagreed: "Cao Cao asked the main guild to hunt Jiangxia, harboring evil intentions and ill intentions. ”

Sun Quan said: "There are only more than 30,000 people in our army who can participate in the battle, and Liu Qi and Liu Beiduo in Jiangxia say that there are only 20,000 horses, how can they resist Cao Cao's millions?" ”

According to Zhou Yu's analysis, Cao Cao incorporated 300,000 Yellow Turbans in Qingzhou, pacified Yuan Shao's army of 560,000, recruited 340,000 troops in the Central Plains, and now has 280,000 troops in Jingzhou. That's more than 1.5 million. However, the northern states and counties need to be guarded by soldiers and horses, and the army that can go south is only about 200,000. Ma Teng and Han Sui occupied Kansai, the rear was unstable, and there should be worries; Jingzhou's surrender is still suspicious, and it may not be convinced, and the army's heart is shaken; Long marches, tired from afar, far from the rear, difficult to supply, poor supply of military supplies; If you give up the saddle horse, you will have a boat, and you will not be used for a long time, and you will not be used to water warfare; The cattle pointed south, pride and despised the enemy; The northern soldiers went south, did not learn about water and soil, and the army was very prone to epidemics. Although the Sun-Liu coalition army is only 50,000, it is easy to supply, familiar with water warfare, and the stakes are high, and the morale is strong.

Zhou Yu's remarks strengthened Sun Quanlian's determination to resist Cao Cao and his confidence in defeating Cao Cao, and ordered Zhou Yu to be the commander-in-chief and lead 30,000 troops to join Liu Bei to break Cao together.

Zhou Yu received the order, and the unified army set off from now on, and went to the village of Sanjiangkou.

Suddenly, Cao Cao sent an envoy to write a book, Zhou Yu called in, took the letter, and saw the words "Han Prime Minister Fu Zhou Dudu Governor to open it" on the cover, he was furious, and did not open it, tore the book to pieces, threw it on the ground, and drank and beheaded the envoy.

Lu Su said: "The two armies are fighting, and they will not be killed. ”

Zhou Yu said: "Only by cutting the envoy can you demonstrate," so that the future envoy will be beheaded, and the head of the person will be held back, that is, Gan Ning will be the vanguard, Han Dang will be the left wing, Jiang Qin will be the right wing, and he will lead the generals to respond, and the fourth watch will make food in the coming day, and the fifth watch will start the boat, and the drums and shouts will advance.

Cao Cao had to report that Zhou Yu had destroyed the book and beheaded the envoy, and was furious, so he ordered Cai Mao, Zhang Yun and other Jingzhou generals to be demoted to the front, and they were the rear army, urging the warships to march to the mouth of the three rivers.

I saw the ships of Soochow early and came from the river.

The first general, sitting on the bow of the boat, shouted: "I am Ganning!" Who dares to fight me? ”

Cai Mao ordered his younger brother Cai Xun to advance.

The two boats were approaching, Gan Ning took a bow and arrows, and looked at Cai Xun to shoot it, and Cai Xun fell in response.

Gan Ning drove the boat forward, and ten thousand crossbows fired at the same time. Cao Jun couldn't resist.

Jiang Qin on the right and Han Dang on the left rushed straight into Cao's army.

Most of Cao's army were Qing and Xu soldiers, who had never been accustomed to water warfare, and on the river, the warships were swaying, and they could not stand on their feet.

Gan Ning and other three-way warships, crisscrossing the water, Zhou Yu urged the ships to help the battle, and the Cao army was shot with arrows and cannons, countless, from the time to the time.

Although Zhou Yu benefited, he was afraid that he would be outnumbered, so he ordered Ming Jin to collect the ship.

Cao Cao's army was defeated at the mouth of the Sanjiang River, and Cao Cao returned to the dry village of Wulin (in Honghu, Hubei) and reprimanded Cai Mao and Zhang Yun.

The two argued: "The Jingzhou naval army has not practiced for a long time, and the sergeants of Qingzhou and Xuzhou have not practiced water warfare, so they have been defeated. And suggested that the water village should be set up first, with the Qingxu army in the center and the Jingzhou army outside, practicing day and night, and then marching.

Cao Cao obeyed his words and ordered the two to train the navy by themselves.

The two set up 24 water gates along the river, with the big boats living outside the city and the small boats connecting with each other inside, and at night they lit up the lights to illuminate the water surface red, and the fireworks on the shore were endless for more than 300 miles.

It is said that Zhou Yu returned to the village of Chibi (now northwest of Chibi City, Hubei) across the river from Wulin, rewarding the three armies on the one hand, and sending people to report to Sun Quan on the other.

That night, Zhou Yu climbed high to watch, only to see the fire in the west. Left and right said: "This is the light of the lights of the Northern Army." ”

Zhou Yu was shocked, ordered someone to pack up a building boat, and led several generals the next day, each with a strong bow and a hard crossbow, to board the boat and go to Cao Cao's water village to secretly peek at the reality.

Approaching the water village, Zhou Yujiao put down the stone pier that tied the boat, climbed the stone pier to inspect it, and was shocked: "So deep in the wonder of the navy, I don't know who the governor of the navy is?" ”

Left and right said: "Cai Mao, Zhang Yun." ”

Zhou Yu thought secretly: "The two of them have lived in Jingzhou for a long time and are familiar with water warfare, so they must be eliminated before they can break Cao." ”

I was peeking into the room, and I saw the flag dancing in the water village, and I knew that I was aware of it, so I hurriedly put away the stone pier, turned the bow of the boat, and flew back. By the time the Shuizhai boat came out to catch up, Zhou Yu's boat had sailed more than ten miles.

Zhou Yu saw that Cao Cao appointed Cai Mao and Zhang Yun to coach the navy, which was a problem for his henchmen and wanted to get rid of him. was thinking about it, and suddenly reported that Jiang Gan, a former classmate and close friend, had come to visit by boat from the other side.

Jiang Gan, whose name is Ziyi, a native of Jiujiang (now Shou County, Anhui), is known for his eloquence Jianghuai, and was recruited by Cao Cao as a guest of the tent, so he recommended himself to say that Zhou Yu surrendered to Cao.

Zhou Yu wanted to sleep, but someone brought a pillow; wanted to stab the enemy with a knife, but someone sent a knife, so he began to design and use a plan, causing Jiang Gan to be tricked.

Zhou Yu first set the rule of "friendship between friends and friends" and not mentioning "military affairs" at the banquet of the heroes of the conference, and sealed Jiang Gan's mouth; Then he showed Jiang Gan the strength of Jiangdong's heroes and heroes, and showed off his status of "meeting the master of his confidant" and being trusted and reused, and cut off Jiang Gan's idea of surrendering.

At night, Zhou Yu and Jiang Gan fell asleep, pretending to be drunk and asleep, inducing Jiang Gan to steal a letter forged by Cai Mao and Zhang Yun to surrender to Soochow, and also arranged for Jiang Gan to secretly contact Jiang Gan with the plot of "someone from Jiangbei is here", so that Jiang Gan was convinced of the letter.

Jiang Gan was worried that he had not completed the mission of surrendering Zhou Yu, but fortunately he got this important "military information", and slipped back to Cao Ying's camp overnight to report to Cao Cao.

Cao Cao really fell for Zhou Yu's counter-plot and killed Cai Mao and Zhang Yun.

Zhou Yu made a credit for his classmate in the credit book.

"The Heroes will Jiang Gan steal books - the big one" will be passed down to future generations.

However, it was said that Zhuge Liang's tongue was fighting against Confucianism, and Zhou Yu was intellectually excited, and Sun Quan was determined to unite against Cao, and was arranged to rest in the post house.

On this day, he was thinking about a plan to break the enemy, and suddenly reported the arrival of his brother Zhuge Jin, hurriedly entered, hugged and cried, and poured out his brother's friendship.

Zhuge Jin complained: "My brother has come for a few days, why don't you go home to talk to each other." ”

Zhuge Liang said: "On the order of Uncle Huang, I came to Wu Hou to fight against Cao, and he should be public first and then private." ”

Zhuge Jin cried and said, "Do you know Boyi and Shuqi? ”

Zhuge Liang secretly thought: It must be Zhou Yujiao who came to persuade me, so he replied: "Boyi and Shuqi are ancient sages!" ”

Zhuge Jin said: "Although Boyi and Shuqi starved to death at the foot of Shouyang Mountain, the two brothers were also in the same place. You and I share the same milk, but each has its own master, and the sky is on its own side, and we cannot meet together at dusk. Compared with Boyi and Shuqi, can you not be ashamed? ”

Zhuge Liang said: "What the elder brother says is love, and what the younger brother keeps is righteousness." You and my brothers are both Han Chinese, and now Uncle Liu Huang is the head of the Han family. If my brother can leave Soochow and work with me Uncle Liu Huang, he will be worthy of being a Hanchen, and he will have to get together with flesh and blood, wouldn't he be ruthless and righteous? ”

Zhuge Jin secretly thought: I was entrusted by Zhou Yu to come to persuade him, but I was persuaded by him. So he said: "Don't you know that the Han family has exhausted its qi and has become a zombie, how can the wheels be reversed?" The Liu family is gone forever! ”

Zhuge Liang knew that it was difficult to move his brother, so he said: "Now that the two families are jointly fighting Cao, you and my brothers will work together and do our best to assist." Please tell Zhou Lang back to my brother, but if I am useful, I will never refuse. ”

Zhuge Jin said goodbye to Zhuge Liang, returned to Zhou Yu, and elaborated on what Zhuge Liang said.

When Zhou Yu heard this, he immediately asked Zhuge Liang to enter the account: "On the same day, we will fight with the Cao army, and the troops on the water should be bowed and arrows first." Mr. once said to his brother that he would never shirk what was useful. There is a shortage of arrows in the army today, and I dare to bother Mr. to supervise the production of 100,000 arrows, please don't push back. ”

Zhuge Liang said: "Since it is a joint fight against Cao, it should be a matter of duty, and it is incumbent on me to appoint the governor and serve myself." Dare to ask 100,000 arrows, when will they be used? ”

Zhou Yu said: "Can it be completed within ten days?" ”

Zhuge Liang said: "The big war is coming, if you stay for ten days, you will miss a big event." It can be completed in less than three days. ”

Zhuge Liang based on years of experience in climate observation and research, calculated that the river must be foggy in autumn and winter, so he and Zhou Yu made a military order, teaching Lu Su to prepare 20 grass boats, 30 people per boat, connected by a long rope, on the third day of the fourth watch of the boat, the fifth more close to Cao Cao's water village, drums and shouts, leading the Cao army to fire arrows together, with grass boats to borrow more than 100,000 arrows.

Zhou Yu was overjoyed, came out of the account to greet him, and said with envy: "Mr. God calculates, so that people are respected." "Let's talk about leading Zhuge Liang into the account to drink together, and discuss the plan of fire attack. Exactly: the grass boat borrowed arrows brilliantly, and the fire attack on the water was connected. If you want to know how Zhou Yu burned the warship, and see the next decomposition.
