Night market stall owner Chen Yan accidentally scanned a mysterious QR code and joined the "Red Envelope Group of All Realms". From then on, red envelopes from different time and space dropped out at eight o'clock every night. By grabbing red envelopes, you can randomly obtain fantasy rewards such as ancient martial arts, spells, and spiritual pet eggs. You can also trigger "market tasks" - helping vendors resolve supernatural disputes, solving Feng Shui bureaus for neighbors, and finding lost Horcruxes for old customers. As the level of the red envelope increases, he gradually gets involved in the hidden "Xuanmen World" in the city, and competes with the ancient martial arts family, the demon cultivator forces, and the mysterious organization "Tianji Pavilion". While playing the role of a pig and eating the tiger, he reveals the truth about the "Experimental Body of the Space-Time Administration" behind the red envelope group, and finally becomes the "red envelope envoy" who balances the worlds of humans and demons.
