I Didn't Know I Was Already Invincible（DUBBED）

Logan Carter, the world’s mightiest warrior, was mentally broken by his family to live as a useless outcast.

All mocked the plain nobody, unaware he ruled the realm unrivaled. After easily defeating countless elite masters, Logan learned he was an immortal living among mortals.
