I Joined Dragon-Slaying Academy, But It Turns Out I'm the Dragon King

Urban high-level martial arts and urban fantasy, with no suspense or supernatural horror elements. Special abilities + one female lead + no golden finger + a stable power system + intelligent villains and a protagonist who isn’t invincible. A quick warning: this isn’t a mindless power fantasy, so the early chapters may be confusing while they lay the groundwork and plant clues. If that bothers you, this may not be for you.
