During the Three Kingdoms period, after the death of Liu Bei, the master of Shu, Liu Chan (A Dou) succeeded to the throne. He only knows pleasure, leaving all domestic military and political power to Zhuge Liang. Zhuge Liang joined forces with Wu to attack Wei, conquered Meng Huo in the south and actively prepared for two northern expeditions. On the eve of the last Northern Expedition, he wrote a model of A Dou to show that he did his best for his country and died.

Everything is ready, except the east wind:

In 208 AD, Cao Cao led 830,000 troops stationed in Chibi in the middle reaches of the Yangtze River in an attempt to defeat Liu Bei before attacking Sun Quan. Liu Bei adopted the strategy of uniting Wu against Cao Cao, and Wu Jun against Cao Cao. At that time, Sun Quan and Liu Bei had few troops, while Cao Cao's troops were huge and unstoppable. Zhuge Liang, Liu Bei's strategist, and Zhou Yu, Sun Quan's general, discussed the strategy of breaking the enemy. They all think that only fire attack can defeat Cao Cao. But when everything was ready, Zhou Yu found that Cao Cao's ship was parked in the northwest of the river, while his own ship was on the south bank. It's winter, only the northwest wind. Attack with fire, it is not Cao Cao who burns, but himself. Only when the southeast wind blows can we launch a fire attack on Cao Jun. Seeing that the fire attack cannot be realized, Zhou Yu was so anxious that he vomited blood and was ill in bed. Neither a famous doctor nor a good medicine can cure his illness. At this time, Zhuge Liang went to visit Zhou Yu and asked him why he was ill. Zhou Yu didn't want to tell the truth, so he said, "How can people not get sick when they are in danger?" Zhuge Liang had already guessed his heart, so he smiled and said, "There are unexpected events in the sky. How can people count on them? " Zhou Yu was very surprised to hear something in Zhuge Liang's words and asked if there was any good medicine to treat the disease. Zhuge Liang said, "I have a prescription to ensure that I can cure you." Say that finish, wrote the word 16 and handed it to Zhou Yu. This 16 is: "If you want to break Tsao Gong, you should attack him with fire; Everything is ready, only the east wind. " Zhou Yu was shocked and thought, "Zhuge Liang is really a god!" Since Zhuge Liang guessed his mind, he asked how to break the enemy. Zhuge Liang has rich knowledge of astronomy and meteorology. He predicted that there would be a southeast wind for a few days in the near future, so he said to Zhou Yu, "I have the magical power to call the wind and rain, and I can help you blow the southeast wind for three days and three nights." What do you think? " Zhou Yu said happily: "Don't say three days and three nights, just one night southeast wind, and the big event will be successful!" " "Zhou Yu ordered his men to get everything ready for fire attack, and Zhuge Liang borrowed the east wind to join the army immediately. Zhuge Liang asked Zhou Yu to build a seven-star altar in Nanping Mountain, and then went to burn incense on the altar, saying something and pretending to call the wind and rain. In the middle of the night, suddenly listening to the wind and the flag moving, Zhou Yu hurried out of the military account to look at it, and sure enough, a strong southeast wind blew. He quickly ordered a fire attack. Zhou Yu took Huang Gai and led the burning boat to Cao Cao's water village. When the fireboat approached the water village in Cao Jun, the soldiers were ordered to set fire to the wind. The wind helped the fire, and the fire took advantage of the wind to completely burn down the warships in Cao Ying, and the camps on the shore were also burned down, causing countless losses to military forces. During the fireworks, Cao Cao fled for his life and fled back to Xuchang through the alley.

Pretend to repair the cliff road southbound, secretly retreat to take Chen Cang-do one thing to cover another; Pretend to act in one place and take real action in another.

According to the Records of the Emperor Gaozu, Xiang Yu claimed to be the overlord of the western Chu Dynasty, and then he enfeoffed his territory to various governors. Among them, Ba, Shu and Hanzhong counties were enfeoffed to Liu Bang and established as Hanwang. On the way to expand the territory, Liu Bang ordered his men to burn the plank road just to show Xiang Yu that he had no intention of expanding eastward. After Liu Bang had a certain strength, he seized the opportunity to move eastward quickly. His ambition is to compete with Xiang Yu for Chen Cang. He made a plan of "building a road to by going up one flight of stairs and sneaking into the future". Chencang is the only place for Liu Bang to enter Guanzhong. There are steep mountains between the two places, and Wang Yong and Zhang Han are heavily guarded. According to Han Xin's plan, Liu Bang sent Fan Kuai, the most trusted general, to lead 10,000 people to repair the 500-mile plank road, which was repaired within one month under military orders. Of course, such a huge project cannot be completed even in three years. It is this that confuses and paralyzes Chen Cang's defenders. Zhang Han, the brave king of Chencang, never imagined that Liu Bang's elite troops actually touched the unknown path and attacked Chencang over mountains and mountains. Liu Bang successfully advanced into Guanzhong, gained a firm foothold through "building the road to success", and opened the curtain of his career in the Han Dynasty.
