Arc 8White Snake and Underworld Assassins
Du Yu completed the White Snake legend despite attacks by assassins serving Sage, then traveled to the Underworld and recruited their present-day selves. He suspected his future self was Sage and returned to discover that the unresolved legend involving Black and White Impermanence had undergone a Flashback.
- Du Yu persuaded Fahai to take Xu Xian to Jinshan Temple, where Medusa's flood brought sea troops into battle with Li Jing's heavenly forces.
- Two assassins attacked Du Yu on Sage's orders, while Xu Xian stabbed Bai Suzhen and Medusa turned Xu Xian to stone below the head.
- Li Jing released Bai Suzhen from Leifeng Pagoda, and Du Yu completed the White Snake legend after Bai Suzhen and Xiao Qing encountered Xu Xuan.
- The Queen Mother of the West explained Houtu's lost memories of Xingtian, and Du Yu accompanied Qu Xi and Weaver Girl to seek Meng Po's help.
- Du Yu recognized an assassin's present-day self at Meng Po's residence and sought An Lushan's stolen soul fragment to save the man's younger brother.
- A Can killed An Lushan and joined A Kui in another attempt to kill Du Yu, but Wazhang protected Du Yu and forced the future assassins to withdraw.
- Du Yu restored the present-day A Kui's soul fragment, recruited both brothers, and suspected that his future self was Sage.
- Du Yu parted with Medusa and confirmed with Zhan Qisheng that Black and White Impermanence's unresolved legend had undergone a Flashback.
