If Chu Yunfan didn't die today, then Great Wei would have to pay an even greater price in the future. If Chu Yunfan escaped, then the two of them would be responsible for giving him the last stab.
Originally, there was no such step, but since Chu Yunfan had repeatedly surpassed everyone's understanding, no one knew if he had any other trump cards. That was why the Emperor of Great Wei sent these two people as the last layer of protection.
In Great Wei, only Yun Huang and these two could suppress Chu Yunfan. However, Yun Huang was the sect master of the Monster Subduers. He was stationed at the western border of Great Wei to suppress the monsters all year round. He would not make a move easily. Moreover, Yun Huang was the chairman of the Core Council and would not listen to the emperor.
Therefore, these two were the final trump cards.
