Corpse Betrothal: I Use the Trait System to Crush Demons

[No female lead + decisive and ruthless + trait System + invincible lead + no-brainer wish fulfillment + demons run rampant] For fifteen years, Zhang Mo has lived as the Zhang family’s lowliest unpaid laborer. His grandfather favors others, his uncle’s family leeches off him, and they even plan to use his own father’s corpse as a betrothal gift. He thinks his father’s corpse will let him split from the family and escape this misery, until a System notification rings out in his mind: [First encounter with a demon.

In this dog-eat-dog world, Zhang Mo calls the shots!
