Gao Lang, an ordinary programmer who traveled to the world of cultivating immortals, was accidentally bound to the "Personal Design Collapse System" - as long as his master and senior brothers and sisters perform behaviors that are inconsistent with their personality, he can receive rewards. He originally just wanted to survive until retirement, but he found that his master was a "dark" villain, who was kind on the surface, but secretly murderous; the elder sister was cold and abstinent on the surface, but in private she was a rotten girl obsessed with romance novels; the second brother was elegant and easy-going on the surface, but was actually a violent old man... The most frightening thing is that all the characters set by the laws of heaven in this world must be maintained, and those who violate it will be punished by God. Gao Lang trembled while helping his master to cover up his lies, while frantically swiping system rewards. As a result, the more he helped, the more chaotic he became. The master's character collapsed more and more outrageously, and the entire world of immortality was on the verge of collapse. When Gao Lang finally accumulated enough points and was ready to run away, the system prompted: The ultimate mission - to completely destroy the master's character, and the reward: Tiandao-level skills. Gao Lang glanced at his master who was playing the role of "Mercy and Mercy", and then at the leader of the Demon Cult who was trembling at his feet. He took a deep breath and said, "Master, I don't know whether to say something or not - your character can no longer deceive me!"
