When Lu Zhao activates his family's ancient bronze box on his twentieth birthday, the nine layers of seals on spacetime shatter with a thunderous crash. The dormant [Burial Time Council] and [Tomb Guardian Legion] emerge at the same time, both intent on claiming the "Zhulong Reverse Scale" inside him, which can rewrite the timeline. As he is forced to flee, he discovers:
- His university advisor is a sword puppet master who guards the Dragon Tomb.
- His childhood sweetheart has the dormant soul of a phoenix inside her.
- Every time he dies, he comes back to life three days earlier, but loses some of his memories.
As nine secret realms appear one after another, Lu Zhao gradually realizes that he is the "anchor" of the seventh reset of time. When Western alchemists bring a prophecy of the apocalypse and an ancestor of the cultivation world reveals the truth about the "spacetime loop," he must choose: become a tool for repairing the timeline, or transform into an evil dragon that tears the cycle apart.
