This NPC Is Too Stable

Trapped in the game world and reduced to an NPC, Zhuo Bufan just wanted to survive. By accumulating proficiency, all skills can be upgraded infinitely, which has become the basis for his survival. It's impossible to fight monsters, let alone download a dungeon. He will never leave the city or have any contact with players. A capable person will never be ahead of others. Live and hide in the city safely, constantly improve your proficiency, and upgrade your level and skills infinitely. Until one day, although the world is big, his invincible figure can no longer be hidden...
