Become a God by Understanding the Weaknesses of All Things

Traveling to a world where cultivation of immortality was not done hard and the boss was miserable. Chen An became one of the "lucky ones" chosen by the Qingyun Sect, the leader of the righteous path, and was sent to work as an undercover agent in the Hehuan Sect, one of the four major demon sects. This undercover lasts for five years, five years! Do you know how I spent these five years? In order to survive, Chen An was bound to the system of seeing through the weaknesses of all things, which can see through people's hearts and see through the weaknesses of all things in the world. When Chen An tried to explore the weaknesses while trying to practice dual cultivation with his senior sisters, he was out of control. Five years later. He had been promoted to the core elder of the Hehuan Sect and was the honorary elder of the other three major demon sects. At this time, the Qingyun Sect suddenly sent someone to tell him that they were preparing to close the net and asked him to cooperate. Close the net and cooperate? Shet! Just wait and tell me and the senior leaders of the four major magic sects! Mainly because I have already invested hahaha
