Li ke is actually a very talented person. He is very much like Li Shimin, with political vision and foresight. He is a rare talent. Li Shimin also likes this son very much. He once wanted to make Li Ke a prince and pass the throne to Li Ke. In Li Shimin's mind, he attaches the most importance to this son and thinks he is the most capable to be emperor.
Because Li Ke's talent and wisdom, as well as Wen Tao's military skills are particularly severe. Therefore, Sun Chang Wuji is very afraid of Li Ke. Sun Chang Wuji always wanted to get rid of Li Ke, fearing that Li Ke would endanger his position after becoming a prince, so Sun Chang Wuji always regarded Li Ke as a thorn in his side.
Li Shimin wanted to make Li Ke a prince, but Sun Chang Wuji was the first person to stand up against it. Under the resolute opposition of mowgli, Li was finally made prince.
Li Shimin knew that Sun Chang's infinite power was too great for him to suppress, so he had to promise, and Sun Chang's infinite didn't want Li Ke to be a prince. Another reason is that Li Ke is not Sun Chang Wuji's own grandson. Li Ke is not easy to control after he became emperor, but the cowardly Li Zhi is easier to control.
When Princess Nanyang rebelled, Sun Chang Wuji took this opportunity to implicate Li Ke, the prince of Wu, and finally killed Li Ke on the grounds of rebellion. Therefore, Li Ke's death was very wrong, and he was beaten to death.
