What happened in the end?

In the end, in order to save the youngest disciple Wen Shi, he brought all the evil obstacles onto himself.

Xie Wen: Officially famous, he is the founder of the magistrate sect. It is said that because he practiced Tao so well that he "did not die a good death". His current identity is that of the expelled descendant of the Zhang family under the judge's sect. Xie Wen is a puppet made by Chen Bu, who felt that there will be a calamity due to him in a thousand years. It is Chen Bu's identity in the mortal world. The soul of Chen Bu will be attached to the puppet, so there is another Xie Wen in the world.
