"Birds are exhausted, good bows are hidden; cunning rabbits die, running dogs cook." This is the fate that many heroes cannot escape, because people are selfish, and when others threaten their own interests, vested interests will find ways to get rid of the threaters. In ancient society, the emperor occupied a dominant position, so when the hero threatened the interests of the emperor, the unlucky people were mostly heroes.
During the Three Kingdoms period, Cao Cao, Sun Quan and Liu Bei, the three tyrants, in the process of fighting the world, also forced one of them to die in order to defend their own interests.
First, Sun Quan forced Lu Xun to die
Lu Xun was one of the four governors under Sun Quan, and he made important contributions to the stability and growth of the Eastern Wu Mountains. During the Three Kingdoms period, most of the fierce generals who led troops to fight were Guan Yu, Lü Bu, and Zhang Liao, while Lu Xun was one of the few Confucian marshals, who had average martial arts, but had a strong ability to strategize and lead troops.
Lu Xun came to prominence at the Battle of Fancheng, when Guan Yu led an army to attack Fancheng, due to Cao Ren's insistence, the two sides fell into a stalemate, at this time, in order to retake Jingzhou, Eastern Wu let Lu Xun take over lü Meng's position as the governor of The Capital, in order to paralyze Guan Yu and make Guan Yu relax his vigilance. When Guan Yu transferred most of Jingzhou's soldiers to Fancheng, Lü Meng and Lu Xun joined forces to attack and took Jingzhou without bloodshed.
In this battle, Guan Yu was defeated and captured, and was killed by Sun Quan, and Lü Meng also died of illness after the war. The loss of Jingzhou and guan Yu were killed, leaving Liu Bei angry and frustrated, and he led an army to attack Eastern Wu. Liu Bei was able to defeat Wu with the strength of the whole country, so the momentum was huge, and Eastern Wu was defeated by the Shu army one after another. At the moment of crisis, Lu Xun stepped forward and once again served as the governor of Eastern Wu, and led his troops to defeat Liu Bei.
After that, Lu Xun became the commander of Eastern Wu's army and led his troops to defeat Cao Wei many times. Lu Xun also became the most important general under Sun Quan, but in Sun Quan's later years, because Lu Xun was involved in the issue of Li Chu, this made Sun Quan dissatisfied and began to alienate and exclude Lu Xun, and Lu Xun also died in grief and anger.
Second, Cao Cao forced Xun Yu to die
Cao Cao's success was inseparable from Xun Yu, who once called Xun Yu "The Son of Wu" and affirmed Xun Yu's help to him.
Xun Yu was a native of Yingyin County, Yingchuan County (present-day Xuchang, Henan), and after Dong Zhuo's rebellion, Xun Yu expected that the war would burn in Yingchuan County, so he left his hometown with his family. He first defected to Yuan Shao, but he felt that Yuan Shao was difficult to achieve great things, so he defected to Cao Cao's account.
The combination of Xun Yu and Cao Cao can be said to be a match made in heaven, belonging to the combination of strong and strong, Cao Cao has the ability and ambition to seize the world, and Xun Yu can help Cao Cao accomplish this. After Xun Yu went to Cao Cao's account, he recommended many talents for Cao Cao, such as Guo Jia, Xun You, Zhong Xuan, Chen Qun, etc., all of whom were Cao Wei's heavy subjects, and at the same time he also advised Cao Cao, governed government affairs, and guarded the rear, which allowed Cao Cao to lead his troops around with peace of mind.
In addition, Xun Yu also revised the strategic policy for Cao Cao many times, such as Cao Cao's strategies such as "deeply rooted in the foundation to control the world" and "greeting the son of heaven" were all offered by Xun Yu to Cao Cao.
Xun Yu's purpose in doing all this was to hope that Cao Cao could revive the Han Dynasty, and Cao Cao's purpose in fighting the world was to become emperor himself, so the two had a conflict. After Xun Yu became a stumbling block to Cao Cao's promotion, Cao Cao transferred him from an important post in the name of Emperor Xian of Han, which made Xun Yu depressed and soon depressed. There is also a saying that Cao Cao sent Xun Yu an empty box (the empty box means self-cutting), and Xun Yu chose to commit suicide after seeing it.
Third, Liu Bei forced Liu Feng to die
When Liu Bei was in Jingzhou, because he had no children under his knees, and in order to win over the clan of Jingzhou, he adopted the son of Luo Houkou as his righteous son.
After this, Liu Feng has been following Liu Bei, and participated in Liu Bei's Battle of Entering Sichuan, the Battle of Hanzhong, etc. Liu Feng is also a relatively brave general, and he is also Liu Bei's righteous son, so his status in Liu Bei's camp is very high, Liu Bei has also been cultivating him as his heir, but after Liu Bei gave birth to Liu Chan, the closeness was reflected, Liu Bei began to alienate Liu Feng, and Liu Chan became his heir.
After the defeat of Guan Yu and Fancheng, he asked Liu Feng, who was stationed in Shangyong, for help. At this time, Liu Feng had an army of 50,000 in his hands, and he was capable of saving Guan Yu, but because the Shangyong region was still unstable, coupled with the fact that Guan Yu was arrogant and arrogant, and looked down on people, Liu Feng did not like him, so he refused to send troops to save Guan Yu, resulting in Guan Yu being killed by Sun Quan.
This incident made Liu Bei extremely dissatisfied, and at the same time, Zhuge Liang was also worried, thinking that Liu Feng was strong in martial arts and was still Liu Bei's eldest son, and liu bei could suppress him when he was alive, but after Liu Bei's death, Liu Chan might not be able to suppress him, so he suggested that Liu Bei take the opportunity to get rid of Liu Feng. After hearing this, Liu Bei suddenly realized that he had killed Liu Feng.
