Naruto: Robot Ninja

Somewhere at the junction of the three kingdoms of earth, wind and fire, there is a small unknown country - the Country of Exile. Those people who were exiled from ancient times because they could not condense chakra lived a life of peace in the barrier, until they were burned, killed and plundered by an unknown ninja army. The survivors fled to other places and pinned their hopes on the only descendant of the village leader. He will bear the fate of the entire survivors and search for the mechanical god who only exists in legends. Fortunately, he found it. Technology countless times more advanced than Orochimaru, powerful energy ninjutsu, and built-in energy battery that is more durable than chakra. Mechanical ninjas do not require training, they only need to upgrade their hardware. "There is nothing that a mechanical ninja cannot solve. If there is, then upgrade them to 2.0."
