The modern metropolis of Yunzhou City appears to be an ordinary first-tier city, but in truth it is a “mortal cultivation ground” where cultivators practice in secret. Cultivators must obey the “Rules of the Mortal World” and never reveal their powers in front of ordinary people, yet they cannot do without mortal resources to support their cultivation. For example, Foundation Establishment cultivators need iced cola to cool the fire in their hearts, while those preparing to undergo tribulation must eat extra-spicy hot pot to build up their yang energy. The protagonist’s employer, Speedy Delivery, is secretly a “cross-realm supply station” for the cultivation world, specializing in bizarre orders from cultivators.
