When Sima Yi learned that the Shu army had gone to war, he led 200,000 troops to meet Zhuge Liang and approached the rising tone.
One day, Sima Yi sent a detective to Yangping for reconnaissance. The detective came back and reported: "Zhuge Liang is stationed in Yangping, and the serenade in the city is weak. Confused, Sima Yi dared not rashly approach the rising tone and ordered the troops to camp 60 miles away from the rising tone city.
At this time, Zhuge Liang has learned that Sima Yi's army is close at hand, and sooner or later, danger may occur.
At this time, Zhuge Liang was still taking his time. He called his men together and said to them unhurriedly, "Don't panic. Open the city gate and send some old and weak soldiers to clean the street outside the four gates. Violators, hey. "
The next morning, the detective Sima Yi sent to Yangping came back and reported: "Yangping City has four doors wide open. There is no movement in the city, it is very calm. Only some old, weak and disabled soldiers are cleaning the streets there. " Sima Yi believes that Zhuge Liang has always been cautious in fighting and never took risks. Since he knows about me, Enemy at the Gates, how could he be so careless? There must be an ambush, deliberately creating this illusion, which led us to be fooled. Better be careful. So Sima Yi ordered the army to retreat and leave Yangping City.
Sima yi led the troops to retreat halfway, and suddenly realized that he was ready to lead the troops back to Yangping, but it was too late, and Zhuge Liang's reinforcements had arrived. Sima Yi lost the chance to fight and regretted it.
Sima Yi was suspicious all his life. Zhuge Liang seized Sima Yi's suspicious personality weakness, cleverly scared Sima Yi away with a false trick, and solved the siege of rising tone.
