Signing In at an Abandoned Mine: Lie Flat and Still Become an Immortal Emperor

Su Xian transmigrates to the world of immortal cultivation and becomes the most useless mine-guarding laborer in the Qinglan Sect, scraping by on spirit-stone crumbs every day. Then he awakens the [Lie-Flat Sign-In System]! He can sign in while sleeping, sign in while slacking off, and even trigger tenfold rewards just by lying still! Others cultivate bitterly for ten years, but one day of lying flat is all he needs. The sect's prodigies? He sends them flying with a single move! An ancient secret realm? He solves it while lying down! A powerhouse from the demon realm? He crushes them with a casual wave! “What? You're saying I'm slacking off?” Su Xian says with a grin as he munches on a roasted sweet potato. “Sorry, I can become an Immortal Emperor just by lying flat!”
