Sign-In System: From Scorned Son-in-Law to Urban Legend

Ten years of humiliation end when Lin Tian awakens a mysterious sign-in system that rewards him daily with game-changing abilities. Once mocked as a worthless live-in son-in-law, he's ready to flip the script and prove that today's underdog becomes tomorrow's apex predator. Armed with random power-ups and an unshakeable resolve, he'll dominate the urban jungle, reclaim his dignity, and show everyone who dared look down on him exactly what they missed. The city won't know what hit it.
