Becoming a God by Seeing Through Everything's Weaknesses

After transmigrating into a world where failing to work hard at cultivation would leave you with nothing but regrets, Chen An became one of the chosen few: a “lucky” recruit selected by the righteous path's leading sect, the Qingyun Sect, to infiltrate the four great demonic sects by going undercover in the Hehuan Sect.

He spent five years undercover. Five years! Do you know what those five years were like for me?

To stay alive, Chen An bound himself to the Insight into All Things' Weaknesses System. It let him read people's hearts and see the weaknesses of everything in the world. When Chen An tried to investigate his senior sisters' weaknesses, he found there was no going back.

Five years later,

he had risen to become a core elder of the Hehuan Sect and an honorary elder of the other three great demonic sects. Then the Qingyun Sect suddenly sent someone to tell him they were ready to close the net and wanted him to cooperate.

Close the net? Cooperate?

Shit!

Go ahead and tell that to the leaders of the four great demonic sects, along with me!
