Lin Ye, an ordinary college student, was bound by the "God and Demon Liquidation System" in a sudden thunderstorm. The cold mechanical sound of the system told him that the chaos of gods and demons has come, and humans will soon be reduced to food, and his mission is to make the aloof gods and brutal demons pay a heavy price as a "slayer". Rejecting the mission = instant erasure. Completing the mission will earn you rich rewards such as god-level skills, magic weapon fragments, and physical transformation. From the moment he was forced to slash at the first monster with his sword, Lin Ye became stronger step by step under the "force" of the system. He tore apart low-level demon soldiers, kicked false god clones, seized divine weapons, destroyed the kingdom of gods, trampled on the demon realm, and trampled the dignity of gods and demons under his feet. When the former prey became a frightened existence, when the gods united to suppress the enemy and the demon king took action himself, Lin Ye held a sharp blade stained with the blood of gods and demons and sneered: "The system forces me? No, now I want to torture you all!" This is a passionate story of a counterattack from a mortal to the nemesis of gods and demons under the spur of the system. Every swing of the knife is accompanied by light that tears apart the darkness, and every killing paves the way for the survival of mankind.
