Honghuang: I Devoured the Demon Ancestor's Remnant Soul

I transmigrate into a Twelve-Grade Black Lotus and devour three fragments of the souls of Luohou, Qiankun, and Yinyang in the Netherworld Blood Sea. The God-Slaying Spear and Qiankun Cauldron are mine, and a System notification flashes: Host detected fusing with the source of the Demon Ancestor. Sign in to claim one Primordial Dao Fruit. First, I'll refine it. Then I'll head out.
