My Naruto System Lets Me Duel Legends

A modern soul wakes up in the Naruto world as Meichao, a critically injured, despised Genin in Hidden Grass Village. Humiliated and bullied for showing a simple act of gratitude to a 'medical tool,' he’s branded a pathetic loser, utterly powerless in a world of ruthless ninjas. His reputation is in tatters, his body broken. But fate intervenes. A mysterious 'Ninja World Arena' system, pulled from his past life's mobile game, manifests in his mind. This isn't just a game; it's a real-time dimension where he can 'invite' any ninja, spar with them, and—most importantly—extract and master their skills. His first 'invite'? None other than the legendary Uchiha Shisui. Can this \"loser\" use a game system to turn the tide, master legendary techniques, and rise above the very ninjas who scorn him? Or will his stolen power come with an unforeseen, terrifying price?
