Chen Mo, a courier company employee who was demoted to the warehousing department, seems to be stoic, but secretly has a golden finger that can communicate with all beasts. He thought he could only live in the mailroom for the rest of his life, until a group of fools calling themselves the "Stupid Thieves Alliance" set their sights on the three-legged golden crow egg sleeping in the company's warehouse, but accidentally awakened the ancient mythical beast. When the stupid thieves' illegal operation attracted the real mastermind - a mysterious organization that can control monsters, Chen Mo was forced to be involved in a secret express delivery battle that spanned the city and the spiritual world. Some people want to steal mythical beasts, some want to snatch eggs, and some want to silence them. Chen Mo must use his golden fingers to conquer more mythical beasts while maintaining his "honest" persona, and fight with stupid thieves to the limit to uncover the underground world of immortality hidden by the express company. When he thought he was just a courier, he discovered that the entire city's spiritual veins were woven into a dragnet by the courier network.
