Starting with a Sign-In for the Chaos Body, How Will You Respond?

Lin Xuan transmigrates into a fantasy world, where he becomes a good-for-nothing live-in son-in-law and suffers endless scorn. On his wedding night, he awakens the sign-in System. He signs in like crazy in the beginner area, gets a Chaos Body from the start, and has his cultivation techniques automatically maxed out. From then on, he begins an invincible journey, crushing every opponent and putting every doubter in their place.
