Ruling the Country

With his body condition, he would need someone to assist him. Xue Yan could govern the country. Even if he didn't know martial arts, he could still stabilize the country. He was the best candidate for ruling the country.

In his previous life, although he knew that Xue Yan was actually Crown Prince Shu, he didn't kill Xue Yan because he saw that Xue Yan was able to govern the country and was more talented than others.

However, he had always been afraid that Xue Yan would find out about his past.

In his previous life, the Supreme Court official had accidentally discovered that Xue Yan was Crown Prince Shu. He invited Xue Yan to a banquet and wanted to let Xue Yan know, but fortunately, Xue Yan did not get the chance to find out. He was afraid that Xue Yan already knew, so when he ordered people to wash the Supreme Court official's family in blood, he also killed Xue Yan.
