Lin Chuan, who ate moldy rice balls in the garbage dump, had been burdened with three million in debt since he was a child, and lived like a dog.
His biggest dream is just to have enough to eat and hold a girl's hand for once.
But when the creditor's knife pierced his chest, the fusion of his blood and the strange dog turned into the heart of a chainsaw that ripped apart everything.
Amidst the blood and debris, he felt for the first time: he was really alive.
In a world of hunters and demons, contracts and betrayals, blood and desire, an endless slaughter has just begun.
He is not a savior, he just wants to live.
But in this hell, surviving means becoming the most cruel monster.
