Traveling through the collapsing world line after the conclusion of "Under One Person", Ling Xiao woke up in a garbage dump and saw Feng Baobao being besieged. Bound to the mysterious system "The Return of Everything" - which can analyze and fuse eight magical skills, but at the cost of burning precious emotional memories. He rescued this innocent girl, but he didn't know that he had been involved in a shocking conspiracy that had been tampered with: the truth of the Jiashen Rebellion was twisted, and Feng Baobao's immortal body was actually the "perfect container" coveted by Duan Muying (in the form of Lu Huan), the founder of Double Hands!
In order to protect the baby, Ling Xiao showed his talents at the Luotian Dajiao, explored secrets in the Twenty-Four Valley, and fled to Nason Island to fight against the encirclement and suppression by the ten guys. Wanxiang Guiyuan analyzed the eight magical skills, his power soared, but his emotions gradually peeled away. When the baby sacrificed his soul to restore his sanity, when Zhang Chulan turned against him because of false memories, when time went back to reveal the cruel truth - Ling Xiao was actually the source of Jiashen's resurrection technique! He, Wugensheng's message and Duanmuying's thousand-year obsession formed a fatal closed loop of cause and effect.
The protection of thirty-six reincarnations finally leads to the fateful decisive battle. Can Ling Xiao use her body as a shield to protect the baby's soul that is "as clean as yesterday"? In this strange world torn apart by conspiracies, the guardian of amnesia and the immortal child will rewrite the end with "the return of all things to their origin". This time, it was her who would protect him forever.
