Oops…Honey, I Really Am the Supreme Mage

A dirt-poor nobody mocked by everyone… is secretly the half-god mentor who vanished for twenty years. As an ancient demon invades and the kingdom faces annihilation, he wipes out its avatar in a single move—shattering everything they believe. His ex humiliates him, nobles trample him, the whole crowd laughs—until the next second, his identity drops… and everyone falls to their knees in terror. The “trash” they despised… is the god they should fear.
