In this age of spiritual qi revival and awakened abilities, an unspeakable forbidden legend circulates in the hidden world.
They say that if you post a task on the "Universal Help" app, you might summon a mysterious powerhouse dressed in a cheap windbreaker.
He can crush an S-rank demon beast with his bare hands, but charges only 50 yuan for a delivery fee.
He can walk straight through the barriers of top assassins, just to deliver takeout on time.
He can slap away a Demon Venerable trying to destroy the world, all because "your messing around made me miss the deadline and lose money."
The major factions are terrified. "Just what kind of reclusive old monster is this?"
The protagonist, Lu Fan, looks at the coupon for a good-review cashback and sighs. "Customers these days are so hard to please. I deliver a letter and get mobbed by a bunch of weirdly dressed chuunibyou types (ability users). Whatever. My next job is unclogging Auntie Wang's drain. I'd better hurry, or I'll miss the supermarket sale."
