I Lay Low in the Cultivation World and Become a Saint, Starting with Self-Castration

Lin Feng transmigrates to a world of cultivation. He has just castrated himself for fun and plans to join the imperial cultivation ranks, only to have his transmigrator identity discovered and his head lopped off with a single stroke. Think he’s dead? No, not at all. With the help of a deduction System, he starts over. If this path doesn’t work, the next one is bound to. His first deduction fails, and he discovers that other transmigrators exist in this world. So he changes his plans: he starts in the mortal world as a martial artist, gets a basic understanding of the place, and only then begins searching for the path to immortality.
