튜토리얼 탑의 고인물

Hyeonu Kim spent twelve years locked inside the Tutorial Tower, a structure whose monsters regenerate endlessly and that nobody had ever been allowed to leave. He cleared it over and over, grinding stats and building his own martial arts, until the system finally told him his loop had been lifted. He walks out stronger than almost any human or monster on Earth, into a world that knows him only as an urban legend, and starts hunting whoever put him in there. This manhwa adapts the web novel of the same name.
