When the fog swallowed Cangnan, the rainy night the 008 Shiva Grudge Incident took his parents, a countdown formed from a fog mark appeared on Su Wang's left arm. It was the contract he made with a mad god who controlled time after touching a “Fragment of the Cocoon.” As a new Night's Watch recruit, he can rewind time by ten minutes, but only at the cost of losing his memories. He teams up with Zhao Mian, Zhao Kongcheng's sister, as the “Reverse-Time Duo,” recreating the conviction that “this strike is going to look really cool” amid the smoke and gunfire. He meets Lin Yuan, a memory backup created by An Qingyu, and searches for the truth behind “betrayal” through hacker code and cracks in time.
From fighting Taotie, who devours obsession, at the “Memory Pawnshop,” to reading Zhou Ping's thousand-year-old obsession with “protecting the human world” on the Nile battlefield; from uncovering the mad past of the “Cocoon,” which was actually the Great Xia god Shizhu, to facing the truth of Zhao Kongcheng's sacrifice, when he chose to become a “time anchor,” Su Wang presses the rewind button again and again, but eventually understands: some regrets cannot be undone, and some sacrifices are choices made to “become the light.” When the Reverse-Time Night's Watch try to sacrifice him to repair the timeline, when Zhao Mian's Star Blade pierces his heart and activates the symbiosis of the fog mark, and when the memories of a million Night's Watch members form a golden web of resonance in the final battle, Su Wang finally raises his blade. This time, he will not turn back the past. He will protect the countless lights burning in this moment.
