Liu Feng was Liu Bei's adopted son, and from the perspective of ability, Liu Feng was definitely above Liu Chan. At that time, Guan Yu sent an army to capture Xiangyang, and finally trapped Fancheng, Guan Yu repeatedly asked Liu Feng to send troops, but Liu Feng was indifferent, resulting in Guan Yu's death. After that, Liu Feng was arrested by Liu Bei, and originally Liu Bei was still hesitating whether to execute Liu Feng, but under Zhuge Liang's strong recommendation, Liu Bei could only choose to give Liu Feng to death. Why did Zhuge Liang insist on getting rid of Liu Feng so much this time? In fact, the reason behind it is not to avenge Guan Yu, but to get rid of this force that may rebel as soon as possible.
Zhuge Liang is not only talented, but it is not difficult to see that he is also a benevolent and righteous person, otherwise he would not have only taken a fancy to Liu Bei among so many warlords, when he was in charge of internal affairs, he cherished the people's strength, and when he presided over military affairs, he personally reviewed all the punishments of more than 20 military sticks before they could be implemented, but what did such a benevolent and righteous person find after Guan Yu was killed? Why did he, who had never spoken in rumors, rush to persuade Liu Bei to kill Liu Feng?
In 219, in order to alleviate the pressure on the western front, Liu Bei ordered Guan Yu on the Jingzhou defense line in the east to carry out the Northern Expedition, in August of the same year, he defeated Yu Ban and besieged Cao Ren, Fan Cheng was in danger, shocking Wei Ting, Cao Cao in order to let Guan Yu retreat, so he colluded with Sun Quan in the south, the two sides reached a secret agreement, by the Wu army to attack the rear of the Jingzhou army, and finally Jiangling and other important towns were taken, he was also defeated on the way back to the division, and retreated to Maicheng.
After being besieged, he only had a few hundred soldiers left under his command, so he wrote a letter to request the rescue of Liu Fengfa, who was closest to him, but he was initially determined by his superiors, the local people's hearts were unstable, and he could not draw military strength to refuse, and his death eventually led to Guan Yu being killed. We know that Liu Guanzhang was very affectionate and righteous, the three of them raised troops together in Zhuo County, fought side by side for nearly 30 years before they had later achievements, although they were monarchs, they were actually brothers, so Liu Bei was both sad and angry after hearing about it.
Liu Feng naturally knew this, so he did not dare to return to the dynasty, and Meng Da, who gave him advice at that time, was even more afraid, he was afraid of Liu Bei's retaliation, and soon after he led his army to surrender to Cao Cao, and then brought troops to fight Shangyong, Liu Feng could not resist and fled in defeat. Although he was afraid that Liu Bei would blame him, he still did not surrender to Cao Cao, because he still had luck and thought that he was the eldest son after all, so he returned to Chengdu.
However, he forgot that his so-called eldest son was actually the same as the fake, because he was only an adopted son, originally surnamed Kou. Because during the Jingzhou period, Liu Bei never had a son, so he adopted one. But soon after, Ah Dou was born, so Liu Feng's position was somewhat embarrassing. When he was adopted, he was already eighteen years old, so Liu Bei and he almost had no father-son relationship, and he wanted to play the family affection card, which may be miscalculated.
When Kong Ming heard that Liu Feng had returned, he hurried into the court the next day and said to Liu Bei: "Feng Gang Meng, it will be difficult to control the imperial system", this time it poked At liu Bei's worries, Liu Chan at that time was only in his early 10s, and this Liu Feng was already in his 20s, rich and powerful, or a fierce general, with experience in commanding troops, and also had his own connections in the army, which was actually a great threat to Liu Chan, plus disobeying the order, seeing death and not saving, so that he lost a love general and brother, Liu Bei thought of this and was suddenly angry, and immediately ordered Liu Feng to be killed.
Kong Ming had never slandered or harmed others in his life, and the reason why he did this this time was also unavoidable. Because he knew that after a hundred years, Liu Bei would definitely pass the throne to his own son, and Liu Chan was weak and weak, and he would definitely need his own assistance in the future. However, if there was a disobedient Liu Feng outside, it would be difficult to deal with, after all, as the eldest son of the emperor, Zhuge Liang would definitely not be able to move him, so he had to eliminate this potential rebel force while Liu Bei was still alive.
