Uncle Jiu: I am the eldest disciple of Mount Mao

Intro: Synopsis: Waking up, he suddenly became Jiu Shu's senior disciple. However, his ending was not good. Fortunately, that rebellious son was not born, and everything could still be salvaged. In this world, demons and monsters run rampant, but there are no immortals or cultivators who can travel thousands of miles in a single step. There are only Taoist priests and Taoist magic. Let's see how Shi Jian, with his own strength, sweeps away demons and monsters, becomes a Heavenly Master, and takes over the position of sect leader. (Supernatural world + Jiu Shu + no female lead + no system + fictional background)
