Chen Changsheng traveled to a seemingly modern world where cultivators and supernatural beings were hidden, and gained the [Life Simulator] and the [Death System]. He discovered that he had unlimited lifespan and the simulator could be used at will. The first mission released by the system is to send off the "Devil God" who is about to be besieged and perished by his enemies. Through countless trials and errors in the simulator, the protagonist found the only way to get close to Tianzun and gain his trust. Finally, at the moment Tianzun died, he sealed him in his body according to his last wish (to prevent the Tao from disappearing), and inherited all the skills of Tianzun. From then on, he appeared to be an ordinary young man, but inside his body was an old devil who taught him taboo techniques at every turn. His daily life has become: using the simulator to find the next "death" target → struggling to improve his cultivation level → accidentally saving the world → gaining the love of the righteous saint → the villains collectively collapsed: "Why did our ancestors pass their skills to this old six before they die!"
