Sick Debtor

When the descendant of the "Credit Knife Man" of the witch doctor line took over the bone knife from his master before he died, he thought he was holding a magic weapon that can help the world. Little did he know that this demonic knife that can absorb disease energy actually uses human life as "interest" - a wealthy businessman borrowed the knife to recover, but the master's body turned into a monster; he passed on the disease energy to his mortal enemy, but in exchange for the enemy's massacre, he hunted for his soul and took his life. By mistake, the apprentice stepped into the abyss of the curse of "credit knife": if the knife absorbs the disease, it will give birth to a life-devouring monster, and the interest of each "credit knife" will eventually point to the scabbard host itself. From the wails of ghosts in the sick well of the royal palace to the reincarnation of the bone deeds in the mass graves, he gradually revealed the truth: the so-called knife creditors are just living sacrifices to the demon sword's scabbard, and each generation bears the blood debt for the sword until their souls are gone. When the bone knife felt hot in the palm of his hand, and the knife-shaped scar on the back of his neck squirmed like a living thing, he had to choose between becoming a new monster host or cutting off the thousand-year curse. The disease is like a vine clinging to his life, and the demon sword is like a poisonous snake eating his heart. Can he break free from the fate of the "scabbard" in the Blood Rain Knife Festival, and let this demon sword that counts on human life finally drink his own blood debt?
