I Have a System, Invincible Under Heaven

He accidentally arrives in another world. What, his aptitude is the lowest grade? You've got to be kidding. Does he have to duel other people, too? Lin Han just wants to lie back and enjoy the easy life of a rich young master. "There's no way I'm cultivating. Not in this lifetime. I'm the second young master of the Lin family. Why would I need to cultivate? What a joke!" But things don't go as he wishes. Under the System's patient persuasion, Lin Han finds himself reaching the pinnacle before he even realizes it. The System is a force to be reckoned with: ruthless and sparing with words. This young master will show you that my System is peerless!

P.S. The title and synopsis are utterly ordinary. The author is in Lighthouse Psychiatric Hospital and has given up on treatment.
