The demon king I raised with my own hands thought he was a chess player, but little did he know that he was just my most eye-catching chess piece. When the so-called "saviors" were defeated and the whole world fell into ultimate despair, they finally saw—— The divine shadow rising from the depths of the Demon King's army is their only...
