The Demon King Cheat System

One day, numerous dungeons emerged in the world, marking the beginning of the “dungeon era” for humans. The leader of the abyss-level dungeon, Ah de sa lai, was defeated by players who used dishonorable tactics. Refusing to accept his defeat, he was reborn as a weak and insignificant player. By chance, he discovered the exclusive boss system and used it to conquer dungeons and acquire the unique abilities of a dungeon master. Thus, he embarked on a path of revenge.
