Luo Yi accidentally discovered the secret of the alien aliens that landed on the earth, and formed a "community of destiny" with a group of funny aliens. They have to hide and survive between the dragnet of official pursuit and the worries of daily life, while at the same time solving the mystery of their own identities and the meaning of traveling around the earth. They fight, laugh and curse with each other, accumulating trust, growth and courage in the midst of crises, and detouring between the earth and the higher-dimensional mysteries of the universe. Under the humorous and brisk writing style, every crisis is resolved into a ridiculous and funny "big adventure", giving birth to a legendary "interstellar gang". In the end, all the mysteries are revealed, and the heroes use the most "Earth-like" way to win a new home that belongs to each other and the Earth.
