The world is dark and ghosts are rampant. Former police officer Ling Hao, who was burdened with family grievances and blood feuds with his colleagues, was unexpectedly gifted an ancient demon sword - "Huiming" in despair. This sword feeds on sins, and every time it is unsheathed, it will eat the soul of the sinner, and force the wielder to experience his life's sins and pain.
With the Sin-Eating Blade in hand, Ling Hao was forced to embark on a dark road full of thorns. He is both the "executor" who judges sins and the "container" who endures endless pain. The whispers of the demon sword are always confusing, the memory of the sinner erodes the mind day and night, and the alienation of the body is shocking. On the way to pursue the truth and redemption, he gradually discovered that the real terror does not come from demon swords or evil spirits, but from the complexity and darkness deeply rooted in human nature.
Every swing of the knife is a torture of the soul; every devouring may lead to eternal destruction. Will he become a practitioner who cuts off his sinful karma, or will he eventually become a puppet controlled by the demon sword and only know how to hunt? In this abyss of terror and fantasy, Ling Hao must hold on to the last glimmer of humanity in his heart and find his own path to redemption amid endless sin.
