An ordinary person diligently works their way up to become the world's strongest.

Luke and Riri were childhood friends in a remote village.

They both underwent the 'Ritual of Blessing,' which bestowed upon them skills and a divine calling. However, while Riri received the highest-ranking profession, Luke was assigned the lowest.

Luke was resented by the kingdom's upper echelons and exiled from the country.

Lacking talent, a divine calling, and even divine skills, Luke reluctantly continued to diligently train as an adventurer. Yet, his growth rate proved to be astonishing.

With a cheat-like growth that instantly overtakes everyone around him, the protagonist eventually becomes the strongest.
