Immortal Venerable Shen Xianyu was kicked down to the mortal realm, stripped of 99% of his immortal power. All he had left were divine tricks for boiling and deep-frying oden, and blowing things away with a hair dryer.
Forced to take a job at Good Luck Convenience Store, he discovered he had become the director of the neighborhood committee for the city's monsters:
The refrigerator kept complaining about arthritis, a gang of plastic bag sprites teamed up to steal spiritual energy, and heavenly bureaucrats kept chasing after him to deduct his merits!
He had planned to slack off and coast through life. Who knew the store manager was a retired fox spirit, the cashier a socially anxious fox girl, and even the stray cat had become his direct superior? When his old phone flashed a “Save the World” quest, Shen Xianyu clutched his barely warm paycheck and roared, “Can't I just skip work?”
It wasn't until the oden burst with golden light and instant noodles rose into a ladder to heaven that he realized saving the world meant finding ice cube trays for the freezer spirit, helping the abacus spirit find a home, and turning the sharp-tongued manager who kept threatening to “deduct his pay” into his strongest ally.
In one sentence: I save the Three Realms by making oden at a convenience store
