In 219 AD, Guan Yu, a famous general, was stabbed in the back by Lu Meng, and finally his head was different. When Cao Cao received Guan Yu's head, although he couldn't help but be sentimental, he was more joyful, and even said, "Yun Chang is dead, I will be safe." However, Sima Yi, who was on the side, said a word, which made Cao Cao wake up suddenly, and even ordered someone to build Guan Yu's sandalwood body and bury him.
So what did Sima Yi say to him so that Cao Cao could have such a change all of a sudden?
In 219 AD, Cao Cao and Liu Bei lost their battle for Hanzhong and retreated to Chang'an. However, soon after, Guan Yu, who was guarding Jingzhou, responded to Liu Bei and led his army north.
At that time, Cao Wei's troops were a little stretched, and Cao Ren could only defend Xiangyang and Fancheng to stop Guan Yu's northward pace, but he was unable to repel the other party at all. Cao Cao put together everything to make Yu Ban the commander and Pang De the vanguard, leading an army of 30,000 to rescue Cao Ren.
With the support of 30,000 troops, Cao Ren's pressure plummeted, so Yu Ban led his army to be stationed in Fanbei to form a corner with Fancheng to deal with Guan Yu's attack.
The arrival of a heavy rain directly achieved Guan Yu's prestige. Guan Yu took advantage of the surging Han water to flood the Seventh Army, defeated the forbidden army in one fell swoop, and even captured Yu Ban and Pang De. The demise of the reinforcements put Fancheng in jeopardy.
For a time, Guan Yu became famous, and Cao Cao heard about it, worried that Fancheng would not be able to hold it, and once wanted to move the capital, but under the persuasion of Sima Yi and others, he decided to continue to send reinforcements and form an alliance with Sun Quan.
Sun Quan had long been dissatisfied with Guan Yu, so he instructed Lü Meng to secretly dispatch troops, intending to sneak attack Guan Yu's rear and seize Jingzhou.
Although Guan Yu's army was huge, the long-term siege also made his soldiers tired. Cao Wei's reinforcements, led by Xu Huang, defeated Guan Yu head-on. When Guan Yu retreated, he learned that the rear had been broken by Jiangdong, and he was already rootless, so he could only lead the remnants of the army to retreat to Maicheng.
After a short rest, Guan Yu broke through at night, not wanting Jiangdong to have an ambush, and was finally killed together with his eldest son Guan Ping.
After Sun Quan learned the news that Jingzhou had been seized and Guan Yu was dead, he was first happy, and then he was worried. Because Guan Yu and Liu Bei are brothers and sisters, now that Guan Yu has been killed, Liu Bei will definitely raise troops to retaliate. So Lu Xun was summoned to discuss countermeasures.
Lu Xun proposed that he could lead the water to the east and give Guan Yu's head to Cao Cao, so that Liu Bei would definitely think that Cao Cao was the mastermind who killed Guan Yu.
Sun Quan thought it was very reasonable, so he put Guan Yu's head in a wooden box and gave it to Cao Cao in the form of a gift.
When Cao Cao received Guan Yu's head, he first recalled the past with Guan Yu, and after being sad for a while, he became happy. Because Guan Yu put too much pressure on himself before, he had the idea of moving the capital. Now that Guan Yu is dead, he said to his civil and military: "Now that Guan Yu is dead, there is no longer a huge threat in the world." ”
Just when the civil and military capitals were overjoyed, Sima Yi stood up and poured a basin of cold water: "Prime Minister, this is Sun Quan's plan, in order to bring disaster to the east, he wants us to bear Liu Bei's anger." ”
When Cao Cao heard this, he calmed down and thought about it, and suddenly felt a burst of shock, indeed as Sima Yi said, this was Sun Quan's plan. So I asked how to crack it.
Sima Yi proposed that Guan Yu should be buried with the highest standard to show our respect for him, so that it can be cracked.
Cao Cao already admired Guan Yu, and this plan won his heart.
Subsequently, Cao Cao asked people to use good gold silk sandalwood to create a body for Guan Yu, and then buried him with the gift of a prince, and he also came to pay tribute in person.
When Liu Bei heard the news, he immediately understood that Guan Yu's death was committed by Jiangdong. Later, Zhang Fei also died at the hands of the rebels, and his head was sent to Jiangdong. Such a new hatred and old hatred made Liu Bei unable to bear it. Finally, in 222 AD, he personally led a large army to conquer Sun Quan to avenge Zhang's revenge.
