National NPC: I can Kill Players

A devastating fire descended from the sky, transforming the entire Blue Planet into a doomsday game for higher-dimensional humans. All the native inhabitants of Blue Planet became NPCs and monsters in the game, destined to be hunted and enslaved by "players." Yunqi, who traveled from Earth, accidentally created the only professional Death Knight, possessing the ability to kill players that shouldn't exist. Can't gain experience and level up? It doesn't matter. As long as my monster affixes are high enough, my level will automatically surpass the top players. Your level will be my level, and you won't enjoy the bonus of equipment attributes.
