Help! the NPC in This Copy Has Become a Master!

"Help! The NPC in this dungeon has become a spirit!" When the player wailed, the skeleton soldier Kaka just silently quenched the poison on the newly acquired ax (nothing). A system bug caused the bottom monsters Kaka (Skeleton Soldier), Gulu (Goblin) and Piaopiao (Ghost) in the infinite dungeon to awaken their consciousness. They were fed up with being killed repeatedly by players, and unexpectedly discovered that they could gain experience points by counter-killing players! Thus, a team of "villains" with a unique style of painting was born! Digging holes, sneak attacks, knocking sap, mental interference... You can't think of it, but you can't do it without them (as long as your strength allows)! See how the loser NPC uses bugs and wisdom to survive in the gap between players and the system, pick up equipment, grab experience, and step by step grow from a monster in the novice village to a natural disaster-level existence that makes all players fearful! Unlimited flow of anti-routine flow from NPC perspective, relaxed and funny, and upgraded wits!
