Thirty-year-old Niu Dazhi was originally just the most "unreliable" agent in the Earth Security Agency. Who would have thought that he accidentally discovered the complaining alien pet "Dumbhead" in a garbage dump. At the same time, a mysterious alien refugee organization quietly sneaked into the earth. Niu Dazhi teamed up with scientist Zou Kexin, who spoke as fast as a machine gun, and director Sun Batian, who looked gentle but was actually suspicious, to get involved in the power game between alien forces and the earth. Nonsensical hilarious chases, mind-numbing technological crises, and the ultimate choice between earth and foreign lands all advance the plot in Niu Dazhi's gags. In the end, they reversed the crisis, unlocked the possibility of symbiosis between humans and aliens, and made the earth a place of interstellar healing. The story has a tight rhythm, ups and downs, and the characters are humorous and optimistic, and they complete their self-growth while saving the world.
