The Great Demon System

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.
