【Book 2 released on March 19】 Solo adventurer Zion challenged a high-difficulty dungeon beyond his capabilities and died. His undead body began moving, wandering through the dungeon. By continuously defeating monsters, he grew stronger, undergoing multiple evolutions. When he regained his self-awareness, he had become the strongest undead, the "No Life King." Upon learning of the appearance of a new great calamity, humanity was filled with terror and despair. "It's the end of the world..." "Don't worry, I'm not a bad undead!" "HIIIIIIIII!" "...Why?" This is a comical story of the strongest undead, who has absolutely no intention of destroying the world, and the humans who are (unnecessarily) terrified of him.
