Sin System: Demonic Harem After Reincarnation

Zevian Rook had three things going for him: a scholarship to an elite university, $173 in his bank account, and absolutely no ambition to impress anyone. Then a System appeared. [Daily Check-In System successfully activated.] "Cliche." [...] "Can I fly?" [No.] "Heat vision?" [No.] "Then what's the point?" Apparently offended by its own uselessness, the System forcibly upgraded itself. [HEAVEN DEFYING SYSTEM activated!] Its first legendary reward? A nut. Zevian ate it. He probably should have read the description first. The next morning, his glasses stopped working, his body looked like it had been sculpted by an overenthusiastic god, and his supposedly ordinary university life went straight to hell. Rich heirs want to humiliate him. Campus beauties keep approaching him. A gorgeous senior secretly has thirty days to make him fall in love and break his heart. Unfortunately for her, Zevian is more interested in the free meals. And while everyone mistakes his indifference for cowardice, nobody realizes that beneath Zevian's easygoing smile is a man who simply doesn't care about money, status, reputation... or giving arrogant people the reaction they want. Cars? Nice. Mansions? Convenient. Beautiful women? He has eyes. Insult him? Go ahead. Touch someone he cares about? That's when Zevian stops smiling. From a broke scholarship student to a despised son-in-law, from a supposedly useless orphan to the hidden heir of a terrifying family, Zevian will slowly discover that wealth is only the surface of his world. Beyond it lies martial arts, hidden powers, forgotten bloodlines... and the truth behind a System arrogant enough to call itself Heaven Defying. Zevian only has one question. "Can I fly yet?" [NO!]

Ryan Cole gave the Lin family everything. His loyalty, his career,and a bullet that should have killed him. They gave him nothing back but a quiet demotion and a fabricated scandal, then sent three men to finish the job in a back alley. "This isn't personal," one of them says, right before his boot finds Ryan's ribs. "Funny," Ryan spits through blood. "Feels pretty personal from down here." He should have died there. Instead, something else wakes up. ‘THE LIQUIDATION SYSTEM HAS BONDED TO YOU.’ It does not reward violence. It feeds on something far more dangerous, the losses of everyone who ever wronged him. Every ruined contract, every broken alliance, every enemy who underestimates him, all of it becomes fuel for his rise. "I am not an app," the system informs him. "Could've fooled me," Ryan mutters back, and the war begins. From a broke, blacklisted nobody to the founder of an empire no one saw coming, Ryan Cole is done staying quiet. The men who destroyed him are about to learn what it costs to lose to him.
