They All Thought I Was Crazy, Until Something Strange Happened

After transforming into a wealthy loser, I pretended to be stupid during the day and practiced all night long. Relatives laughed at me as crazy, and geniuses from aristocratic families regarded me as an ant. Until the world's strange resurgence, the S-class ghost king tore apart space and descended on the dinner party. When everyone collapsed and ran for their lives, I put down the half-eaten cake and wiped my mouth: "What's the fuss about? Didn't you see me eating?" As soon as he raised his hand, the ghost king was wiped out.
