The Immortal Emperor quit his job and opened a tavern. On the first day, the roof beams collapsed.
He advertised for a waiter, and the Demon Lord showed up. He wanted to experience "smiling service," but one smile sent every customer running.
He advertised for a cook, and a Vermilion Bird came. She cooked with the techniques she used to make elixirs, blowing up the kitchen thirty-seven times and counting.
The accountant stayed after skipping out on his bill. He's a successor of the Confucian Sage, and spends every day using The Analects to figure out how to collect debts.
A little freeloader hangs around the back door. His soul leaving his body after a meal is an everyday occurrence. His father is the Ghost Emperor of the Underworld. He visited once and said, "Pretty good. Better than him tearing down the walls at home."
There's also a mysterious person in the corner who drinks every day and never pays, but everything he says comes true the next day.
The Immortal Realm came to inspect the place, and he put them to work serving dishes.
The Demon Realm came seeking revenge, sat down for a meal, and forgot why they'd come.
The Demon King came to propose marriage, tasted the cook's food, revealed his true form, and ran away.
Relaxed, funny, cultivating, and nonsensical
