As the most disliked outer servant in Qingwei Mountain, I (Lu Chenzhou) was expelled from the mountain by the law enforcement hall as "the following offender" because I stood up for the bullied junior sister. When I was desperate, the mechanical sound of the "Destiny Reincarnation System" suddenly sounded in my mind, and from then on, I started a counterattack of "completing tasks and exchanging opportunities". The system tasks have been upgraded step by step from "rescuing the dying girl", "challenging the monks of the three realms" to "revealing the secrets of the sect". While I obtained top-level skills and ancient elixirs, I successively met the cold swordsman Su Ruochan, the successor of the ghost doctor Lin Shutong, the descendant of the demon cultivator Xiao Yingxue and other beauties, and gradually uncovered the conspiracy of the "fallen from the fairy world" to secretly control the lower world. When Qingwei Mountain, which once expelled me, was facing annihilation, and when the "man of destiny" sent by the immortal world declared that I was a "variable that hinders the road," I clenched the sword in my hand - in this life, I decided to do my own destiny!
