An alien scout transforms into a fashionable beauty and sneaks into Shanghai. She buys steamed buns and reads newspapers, deciding this Earth has only ordinary technology. One false report is sent, and giant beasts and fleets arrive one after another. Who would have thought the old man selling steamed buns speaks of 'Heaven and Earth in Law Form' the moment he opens his mouth; the water patrol officer turns into a dragon the next second; even the courier can ride the clouds! She hurries to stop the invasion, yet Yang Jian confiscates her communicator and even impersonates her identity to urge the enemy to send more troops. Sun Wukong and Nezha take turns slaying monsters, Athena chases after Yang Jian consumed by jealousy, while she alone focuses on escaping. She barely flees back to the spaceship and urges her companion to open a wormhole back to the home planet, only to hear Yang Jian’s greeting from behind. Hundreds of tourist buses follow close behind.
