National Copy: I Am the Strongest by Following You

[Game text + unlimited streaming + easy and funny] Others travel through time to be the protagonist, but why does my system ask me to be the NPC, and why does your wording mean "following!" Traveling to this dungeon world where games are paramount, I wanted to be the protagonist and live a wonderful life with great vigor, but my system forced me to be an NPC! I wanted to uprightly abandon the system and become stronger on my own, but when I discovered the bug, I said it was really cool, and from then on I became uneasy in the game copy. In the dungeon: "Damn it, what the hell is this NPC? How come I was instantly killed with just one strike? There must be something wrong with the difficulty of the dungeon! ｀Д´|" "No, why does this NPC look so familiar? Didn't he come from the previous world?" Forum: "8Us, I discovered a shocking secret. I saw the same NPC in several unrelated dungeon worlds. I suspect there is some secret plot in him!" "Does anyone know who the special player the system prompts is? It seems that someone is eyeing me, and my back is getting cold (≡Д≡;)" Ye Buxie looked happily at the players asking for help on the forum, and then cut his throat with a knife. "My name is Ye Buxie (yé), but I prefer you to call me by my player ID [xie (yé) page]. Remember this word is pronounced twice."
