Liu Feng was a figure during the Three Kingdoms period, he was Liu Bei's son, but he was only an adopted son, he was powerful, fierce and courageous, quite martial arts, and was once trusted by Liu Bei.
Liu Feng was Liu Bei's support, and it stands to reason that Guan Yu was his uncle, but later Guan Yu was trapped by Eastern Wu, and Guan Yu sent people to ask Liu Feng and Meng Da who occupied the upper yong for help, but what Guan Yu didn't expect was that Liu Feng did not save him, causing Guan Yu to lose his last glimmer of hope, and as a result, he was captured and killed.
Later, Liu Feng and Meng Da were at odds, and Meng Da feared that Guan Yu's death would blame Liu Bei, so he switched to Cao Wei.
After Meng Da surrendered to Wei, he was taken seriously by Cao Wei, and soon Meng Da sent people to persuade Liu Feng to surrender, but Liu Feng refused. Afterwards, Meng Da sent troops to attack Liu Feng, who was defeated due to the rebellion of his generals.
Liu returned to Chengdu after the defeat, and Liu Bei blamed him for not having a feud with Meng Da, let alone saving Guan Yu. Liu Bei did not want to punish Liu Feng heavily, but at this time Zhuge Liang advised Liu Bei to give Liu Feng death.
Then why didn't Liu Feng save Guan Yu? Why did Zhuge Liang persuade Liu Bei to give Liu Feng death?
There was a reason why Liu Feng didn't save Guan Yu. Liu Feng's death had a lot to do with Guan Yu's death, and Zhuge Liang advised Liu Bei to give Liu Feng death for another reason.
Liu Feng was Liu Bei's adopted son, and at the beginning Liu Bei only had fame, no territory, and nothing. But then Liu Bei's strength became greater and he also had his own territory. At the critical time, he also had his own son Liu Chan.
Liu Feng's hope of succeeding to the throne is getting smaller and smaller.
More importantly, Guan Yu and Zhang Fei were the people Liu Bei trusted and relied on the most, and Liu Bei had also asked Guan Yu about the successor king.
At this time, Liu Feng hoped that his second uncle could speak for himself, but Guan Yu said: "Liu Feng is only an adopted son, and A Dou is a parent-son." Guan Yu's meaning is obvious, of course, the pass on to A Dou.
After Liu Feng learned this, he naturally resented Guan Yu in his heart.
Moreover, when Guan Yu was besieged by Eastern Wu, although Liu Feng and Meng Da occupied the upper place, one occupied a short time, and the other did not have many troops, and the two of them feared that they would not be able to save people and lose their troops.
Importantly, at this time, Meng Da revived the old matter to Liu Feng, saying that Guan Yu did not support his succession, and said something that Guan Yu did not treat Liu Feng as a nephew.
After Liu Feng heard this, he was angry in his heart, so he thought that he had just occupied Shangyong and did not rescue Guan Yu.
Eventually, Guan Yu was captured and killed by Eastern Wu.
Guan Yu has an extremely important position in Liu Bei's heart, and Guan Yu's death, Liu Bei will naturally blame Liu Feng and Meng Da while suffering from the pain.
Meng Da was afraid of Liu Bei's guilt, coupled with Liu Feng's discord with him, so he surrendered to Cao Wei, and soon Meng Da led troops to attack Liu Feng, and Liu Feng was defeated and returned to Chengdu due to the defection of his generals.
After Liu Bei saw Liu Feng, he naturally blamed him. Originally, Liu Bei did not want to kill Liu Feng, after all, he had a father-son relationship for many years. In comparison, Meng Da is even more hateful.
But at this time, Zhuge Liang had other plans,
Liu Bei's own son, Liu Chan, later succeeded to the throne, but he was more than benevolent and lacking in courage. On the other hand, Liu Fenggang is fierce and courageous, and his strength is extraordinary.
Zhuge Liang was worried that after Liu Bei's death, no one could control the fierce and brave Liu Feng, even he as Zhuge Liang may be difficult to control, if it is true, it is undoubtedly a great hidden danger for Shu Han, Liu Chan, and himself, instead of this, it is better to remove it as soon as possible while Liu Bei is alive.
So he said to Liu Bei: In the matter of Guan Yu, Liu Feng's guilt cannot be escaped, and he should be given death.
Liu Bei followed Zhuge Liang's advice and gave Liu Feng death. In this way, his adopted son, who had followed Liu Bei for many years and was in the front, completed his life.
