Mortal Liu Rufeng

There are demons in the world, so why not become a demon? In a world where the strong are respected, the humble young Liu Rufeng has tasted the warmth and coldness of the world. When his seriously ill mother's life hung on a thread, he put down his dignity and begged, but what he got in return was more ruthless trampling. On the day when his survival and dignity were completely crushed, he realized: In this world, kindness is the original sin of the poor, and rules are the shackles of the weak. When he was on the verge of death, he resolutely grasped the only chance of life handed over by the Demon Lord - a "Heart-Corrupting Demonic Art" that can control the world and eat people's hearts. Power is at your fingertips, but comes with a price: every time you advance to a level, your mind will lose a point, and you will eventually become a madman who only knows killing. From then on, he stepped onto a single-plank bridge filled with blood. There is an abyss beneath our feet, and there is eternal night of sinking in front of us. He used a mortal body to perform evil deeds, killing enemies, defying destiny, and struggling to move forward between killing and protecting. This is an epic of revenge in which an ordinary man wields a knife against fate, and it is also a tragic song of humanity in which a kind soul struggles desperately in the endless darkness, between the curse of "eroded heart" and the glimmer of "original heart". When he has the power to subvert the world, will he trample the world under his feet, or will he find the boy who wiped the blood from his mother's mouth in the dilapidated house?
