Naruto: The Vortex of Hard Training

I transmigrated into the world of Hokage and became an orphan of the Uzumaki Clan, with a fate even worse than Naruto's. My golden finger was the dumbest System in history: no quests, no bloodline gifts, and the only way to grow stronger was to train until I dropped. While everyone mocked my training as pointless, the skill points I earned through sweat turned S-rank forbidden techniques into moves I could use like basic attacks. And that blond kid abandoned by the world was the only family I had. “Naruto, watch closely.” I stood between Pain and the Nine-Tails, as countless seals blazed into the sky behind me. “This is the true power of the Uzumaki Clan.”
