There's Something Wrong with My Underworld System

Gu Changan never thought that he would become someone else's savior. He is just an ordinary college graduate. The only thing that is extraordinary is that his father Gu Beichen has been missing for seven years, leaving behind a black crystal stone engraved with ancient texts and a chilling message: **"Don't let them find you. The rules of this world are being rewritten."** Until that day, he bumped into a transparent monster in an abandoned factory. Space twisted and folded in front of him, gravity was reversed, and reality shattered like glass. He discovered that the world was not what he thought it was. Parallel and overlapping physical spaces - the realm of resentful spirits. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
