"Your mission is to defeat the villain Shen Yunfeng and prevent him from becoming a demon!" "What? Isn't this forcing someone to do something difficult?"

When he was found again, he was half dead, blind, his inner elixir was cut, his spiritual energy was lost, and his muscles and veins were severed...
