On the surface, he is an innkeeper, but in reality he is the leader of a demon sect who is afraid of his henpecks. He studies "Three Years to Simulate Being a Father in Five Years" as a martial arts secret book. An upright disciple pretending to be Mr. Accountant, proficient in Excel functions but engraving QR codes on the abacus. The fat cook who kneads noodles with the Eighteen Dragon Subduing Palms, the waiter who has invincible light skills but has to close his eyes when walking up the stairs, and the martial arts leader who writes negative reviews with a judge pen.
