1。 Cao Cao was in trouble and stayed in Lv Boshe. Lv Boshe's family was ordered by Lv Boshe to kill pigs for entertainment. Cao Cao mistakenly thought that the pig slayer was plotting to kill himself, so he suddenly killed Lv Boshe's family. Later, it was found that all the tied pigs knew it was a misunderstanding. When he ran away, he met Lv Boshe and went out to buy wine. When Cao Cao came home from Lv Boshe, he found that all his family members had been killed. The government reported that he had killed Lv Boshe. This time, it was not a misunderstanding, but a deliberate murder. At this time, Cao Cao said a famous saying: "I would rather lose the world than let the world lose me."
There is a shortage of food and grass in this movement. Normal food supply is not enough, but withholding food supply will lead to army mutiny. Cao Cao ordered Dong Wang, a grain officer, to skimp on grain and grass, and the rice yield was less than half of the normal amount. On such a day, the morale of the army was on the verge of mutiny, and Cao Cao suddenly announced that Dong Wang, the grain officer, had taken the commissary for himself, which was a sin to say this plainly. So when Dong Wang was beheaded, the morale was stable, and the saved grain and grass were not investigated. Moreover, everyone thinks that Cao Cao is a good man who makes decisions for soldiers and has gained high prestige among soldiers.
Cao Cao has been worried that someone will be assassinated, so he pretended to be asleep in the middle of the night and kicked the quilt several times. When the guard went to cover the quilt, he suddenly pulled out his sword and killed them, and then fell asleep. Woke up the next morning and pretended not to know, asking who dared to kill his own Sineitai. Others said that Cao Cao committed suicide. Cao Cao said that I like killing people in my sleep, which is actually true. From then on, no one dared to approach Cao Cao when he was asleep, and Cao Cao himself was relieved.
4。 After Cao Cao killed countless people in his life, he "deeply regretted it, ordered a thick burial and set up his family." Those who were killed were loyal ministers of the Han Dynasty who didn't like Cao Cao, as well as new heroes who got carried away like Xu You, and so on. As long as Cao Cao found that he had to kill a person, it was probably for show. The effect is nothing more than killing the person who wants to kill, and pretending that this behavior is only a temporary anger and has been regretted and remedied, so as to prevent other people's rabbits from dying in sorrow and collectively creating Cao Cao's rebellion.
There are many others. I won't go into details here.
