Ash understood immediately. The Uroboros could indeed directly kill all the demigods of the Level Six of Hell, but it would also destroy or heavily damage Level Six of Hell. The Forgotten was sent by it as a tool to pick off those demigods who didn't obediently go to their deaths.
Death Mad glanced at him, took a deep breath, exhaled a smoke ring, and said, "Take out the twenty-sided dice."
Ash was startled. He rummaged in the warehouse for a while before finding the "Prince of Joy's Twenty-sided Dice." This item, used during operator training, allowed them to gain magic experience even if they were arranged for entertainment. However, after Senluo, Ash stopped interfering with the Sword Maidens' training plans, so this tool was naturally forgotten in the depths of the warehouse.
