Changsheng, Except for Me, All the Sects Are Undercover Agents of the Devil.

My name is Xu Heng, and I am a time traveler. Currently, he is pretending to be a newbie in the largest demonic den in the world of immortality. My golden finger can see other people's hidden information, which is good, but also not good... Because I watched helplessly as the head master, who had the [Later Tribulation Transcendence] on his head, was showing me a 'kind' smile. Now, under the eyes of no less than ten giants of magic, I want to secretly learn the supreme immortal method they dream of and ponder a philosophical question. When a room full of wolves thinks each other is a sheep, what's the real sheep to do? Waiting online, quite urgent.
