Ma DaDa is a coquettish young man who makes a living by delivering express delivery. His greatest skill is to do the most serious things in the most unorthodox ways. One day, while delivering a "damaged" package, he accidentally activated the interstellar stowaway in the delivery box - a funny alien creature named Gollum. Gulu not only comes with its own interstellar black technology mall, but is also bound to a "cosmic logistics system", claiming to help Ma boldly build the largest express empire in the galaxy! However, express delivery is difficult to deliver. The interstellar trade routes are in danger, the pursuit of alien gangs, and the covetousness of mysterious organizations are all aimed at this little courier. The most outrageous thing is that Ma boldly discovers that every mysterious package he "accidentally" receives seems to point to a larger conspiracy - the earth is actually being targeted by someone behind the scenes! "I am serious about delivering express delivery; saving the world is purely an accident!" Ma boldly held a cigarette butt in his mouth, rode a small electric donkey, and took the alien dog Gulu with him to start his interstellar express delivery career. Delivering goods, cheating, beating up villains, and flirting with the policewoman... The courier with exposed temperament proves with his strength that the courier boy can also save the galaxy.
