Li Xun of the Tianyun Sect has been living in a cave for thousands of years, relying on pills to build a "human-shaped medicine jar" in the Nascent Soul stage. His greatest wish in life is to become the emperor of Taoism. However, on the day of the sect competition, he encountered a mysterious giant claw that covered the sky and the sun and used the power of the Tao to crush the world. On the verge of death, Li Xun accidentally triggers time regression. Every time he dies, he returns to the cave, and the retrospective timeline continues to extend backwards.
