I Started Cultivating Immortality by Contracting a Toad

Su Yuan transmigrated to another world. From the start, instead of joining a sect or finding an old master, he signed an equal contract with a foul-mouthed toad. Armed with the Heaven-Devouring Demon Hide, he turns every slain demon and cultivator into a Blood and Qi Pill or a Soul Power Pill. He cultivates the Chaos Art, sits atop the Chaos Pagoda, unlocks the world's core, and follows the path of soul refinement. While others toil at cultivation for a lifetime, he uses his enemies as ingredients and demon beasts as pill furnaces. The Qingyun Sect wants to capture him, the Beast Taming Sect is after him, and old monsters from every faction covet the treasures on him. In the end, he and the toad take them all down with dirty tricks. To rescue Murong Qianxue, taken away by a mysterious force, and break the seal blocking Blue Star, he simply refines clones with every attribute: wind, lightning, fire, water, earth, wood, metal, ice, light, and darkness, rotating through them all. You think being a Nascent Soul ancestor makes you impressive? He smashes you with one blow of his staff, then the toad curses you out all over again. Starting with a toad, he curses his way through the entire cultivation world.
