I Became a Passerby NPC in an Online Game

Group portrait writing, very group style. An amnesiac boy traveled into an online game and became a passerby NPC "Qi Hu" But his profession is not a mage with explosive output, not a warrior with handsome posture, or even a nanny with a large capacity, but a human shield that no one can play with. His daily routine is to pretend to be the most stupid in the game, and get the most severe beatings in the next dungeon. The system said, come on, boy!
