On the rainy night when the fog swallowed Cangnan and the 008 Shiva Resentment incident took away his parents, Su Wan's left arm had a countdown made of fog marks - it was the contract he made with the crazy god who controls time after touching the "Fragments of the Cocoon". As a recruit of the Night Watch, he can go back in time for ten minutes, but at the cost of forgetting his memory; he formed a "time-reverse partner" with Zhao Kongcheng's sister Zhao Mian, reviving the belief that "this knife will be handsome" in the smoke of gunfire; he met Lin Yuan, the memory backup body created by An Qingyu, and explored the guardian truth behind the "betrayal" in the hacker code and the time rift.
From the "Memory Pawn Shop" against the glutton that devours obsessions, to reading Zhou Ping's millennium obsession of "protecting the world" on the battlefield of the Nile; from revealing the crazy past that the "cocoon" is actually the Great Xia god Shizhu, to facing the truth of Zhao Kongcheng's sacrifice to become the "time anchor" - Su Wan pressed the rewind button again and again, but finally understood: some regrets cannot be reversed, and some sacrifices are the choice of "becoming the light". When the time-reverse night watchman wanted to sacrifice him to restore the timeline, when Zhao Mian's star knife pierced his heart to activate the mist mark symbiosis, and when the memories of millions of night watchmen were connected into a golden resonance network in the final battle, Su Wan finally raised the knife: this time, he will not reverse the past, but only protect the thousands of lights at this moment.
