Before that, the silver-haired and silver-eyed Daolord actually didn't have such plans. The reason for this decision was mainly because of the Dao Ancestor's evaluation of Xiao Shi and his actions in the end.
Although he did not know the reason why the Dao Ancestor left Xiao Shi behind in the end, as the person who had reset the most times here, he knew that the Dao Ancestor's actions must have an unusual meaning.
This made him decide to increase his "investment" in Xiao Shi and release more goodwill. Usually, the more good karma planted on such a person with greater potential, the greater the return he would receive.
Originally, after Xiao Shi chose the identity of the Slaughter Dao, He no longer thought highly of Xiao Shi. However, after the Dao Ancestor's evaluation and final actions, it made him change his mind. He felt that Xiao Shi might have a chance of controlling the Slaughter Dao.
