Hu Tutu, a young man from Earth, unexpectedly became the representative of Earth due to a "joke interstellar competition". He teamed up with the invited alien Ban Ban and embarked on an interstellar adventure. Humor, misunderstandings, contradictions, and cooperation emerge in endlessly, and laughter and crises burst out at the same time! After experiencing reckless diplomacy, interstellar trials, and rescue crises, a group of characters overturned stereotypes while growing together, worked together to wisely solve interstellar mysteries, and finally won the recognition and respect of many ethnic groups. Exploring identity through laughter, revising interpersonal boundaries through comedy, marveling at alien races, and friendship adventures, concise and compact, full of twists and turns, the book is full of joy and reversal, and finally becomes the founder of the "Earth-Alien Alliance".
