The modern city "Yunzhou City" looks like an ordinary first-tier city on the surface, but in fact it is a "mortal dojo" where cultivators hide their practice. Cultivators need to abide by the "Mortal Code" and are not allowed to expose their cultivation in front of ordinary people. However, due to the needs of cultivation, they cannot do without mortal resources - for example, during the foundation-building period, they drink ice-cold Coke to reduce the fire in the heart, and before going through the tribulation, they have to eat spicy hot pot to accumulate yang energy. The "Suda Takeaway" where the protagonist is located is secretly a "cross-border supply station" in the world of cultivators, specializing in receiving weird orders from cultivators.
