I, Ye Qingxuan, a swordsman saint who once met in the Kunlun Ruins in a thousand years, once traveled into a parallel modern city, inherited the "Netherworld Palace" of the demon sect that everyone was shouting about, and was also bound to a "Heavenly Demon Strategy" system. The system issues tasks: play the role of a villain, punish (acquire), cure (cut off) the son of fate, and you can obtain cultivation, magic weapons, and even fragments of predicting the future. In order to survive and find a way back, I put on a cold mask and started working conscientiously. However, the rumored dandy Gu Yanchen, the shady young master of the Gu family, always appears in my "crime scenes". The suppression of bandits is a lie, but the teasing is real. In the fake drama of "confrontation between good and evil", my cold shell was gradually melted by his cynical affection. Until the ultimate mission of the system was revealed - this world was originally a large-scale experiment controlled by "Heaven", and he and I, one was the selected "virus", and the other was the awakened "anti-virus program". The so-called good and evil are just games that exist in higher dimensions.
