First, Yu Xun, the mastermind of Cao Cao.
Yu Xun was born in an official family. He first joined Yuan Shao's camp and then defected to Cao Cao. Cao Cao and Yu Xun hit it off and commented on Yu Xun: This is my ovary. Later, he appointed Yu Xun as the planner and entrusted him with an important task.
Yu Xun also worked hard for Cao Cao's career. At several critical moments, Cao Cao was saved. When Lu Bu attacked Yanzhou and Cao Cao attacked Xuzhou, it was Yu Xun who saved three cities for Cao Cao. This enabled Cao Cao to avoid the fate of displacement and recapture Yanzhou.
In the most crucial battle of Guandu, Yu Xun put forward the famous theory of four wins, which proved that Cao Cao would win from four aspects: degree, ability, martial arts and morality, and stabilized Cao Cao's mood. Before the battle began, Yu Xun anticipated the end of the battle. When Cao Cao couldn't support it and wanted to remove many capitals, Yu Xun personally wrote to persuade him:
Although the army is short of food now, there is no Chu-Han dispute between Xingyang and Elevation. It's time for Liu Hexiang to quit first, and those who quit first will fail. It has been half a year since 10% of the people have been painting the ground to keep it, choking and not entering. When the situation is exhausted, it will change. When it is used strangely, you must not lose it. ?
Cao Cao accepted Yu Xun's suggestion and persisted. Finally, he waited for Xu You to surrender, burned his lair and won the final victory.
Until the thirteenth year of Jian 'an, Cao Cao conquered Jingzhou Liubiao, and Yu Xun was still assisting Cao Cao. Under the planning of Xun, Cao Cao successfully occupied Jingzhou and forced Liu Cong to land.
Yu Xun is the best way. He served Cao Cao with extraordinary wisdom. It can be said that without Yu Xun's contribution, Cao Cao could not have made such great achievements. Cao Cao also attached great importance to Yu Xun, and even married his daughter to Yu Xun's son, and the two sides became children's in-laws.
Second, Cao Cao and Yu Xun turned against each other.
However, who would have expected that Yu Xun and Cao Cao would eventually turn against each other? The fuse of all this comes from Dong Zhao's recommendation that Cao Cao carry nine tin on his back. At that time, Dong Zhaoxian wrote to ask for Yu Xun's opinion and wanted to get Yu Xun's consent first. Who knows, Yu Xun firmly opposed it. According to historical records, after Cao Cao learned about this, he felt? Will you just calm down? .
Why did the ceremony of lifting lord protector and Nine Tin arouse Yu Xun's opposition? This is because this ceremony was held at the end of the Western Han Dynasty. The object at that time was Wang Mang. Soon Wang Mang usurped the throne and seized the land of the Western Han Dynasty. So this ceremony of adding nine tin to lord protector became the standard ceremony of usurping the throne, which has been handed down all the time.
Dong Zhao's trick can be seen by anyone with a discerning eye, which is to prepare for Cao Wei's generation of Han Dynasty. This conflicts with Yu Xun's idea, and Yu Xun certainly opposes it.
Yu Xun's ideal is to help the Han Dynasty, draw the heroes and restore peace. If he wants to be rich and strong, he can get it from Yuan Shao with his talent. Why go to Cao Cao and go through all the hardships? All the actions of Yu Xun are based on the Han family. For example, he asked Cao Cao to welcome Emperor Han Xian to Xudu. What is his slogan? Serve Tian Zi to please him? What about those? Holding the emperor as a minister? The differences between people are far from different.
However, Yu Xun's insistence clashed with Cao Cao's ambition. Therefore, Yu Xun immediately changed from Cao Cao's main assistant to a stumbling block on Cao Cao's way forward.
Third, Yu Xun died of upholding his integrity.
After learning about Yu Xun's attitude, Cao Cao immediately changed his attitude. For his ambition, he must clear the stumbling block of Yu Xun. In order to prevent Yu Xun from going against him in the capital, Cao Cao invited Yu Xun to join the army.
Yu Xun certainly understands Cao Cao's intentions, but he still has a glimmer of hope for Cao Cao. Before he arrived at the army, he asked to stay and talk with Cao Cao after the ceremony of the labor army. But Cao Cao, who made up his mind, knew what Yu Xun wanted to say and refused him.
From then on, Yu Xun was put under house arrest by Cao Cao in the army, let him participate in military affairs, and never let him go back. Soon, Yu Xun became ill and died of grief. There is another story about Yu Xun's death. It is said that in Xun's illness, Cao Cao sent a box of snacks, but Yu Xun opened it and found it was empty. Yu Xun knew what Cao Cao meant, so he drank the poison and committed suicide. Anyway, Yu Xun died because of Cao Cao.
Conclusion:
Yu Xun died for his persistence. Live as a Han minister and die as a Han ghost. After his death, Cao Cao took the position of lord protector and added Jiu Xi. Yu Xun defended his ideal with his life. Although he can't save the trend of the times, it's a fair death to die for his own ideals. Therefore, Yu Xun did not betray Cao Cao. It was Cao Cao who betrayed his original intention of helping the Han Dynasty.
