Bizarre traces appear in a certain city on Earth. The otaku Li Dawei is accidentally involved in the "Alien Team Trial" of alien creatures, and partners with Earth and alien members with different personalities. They need to resolve alien crises, resolve cultural misunderstandings, and deal with incoming chaotic monsters in the three realms where the earth and alien space intersect. And countless own incidents. In the humorous farce, David and his partners gradually uncovered the truth about the alien world and gained growth and friendship. The three-volume story is divided into earth changes, interstellar adventure, and ultimate reconciliation. Each volume has a tight rhythm and constant jokes, echoing each other to lead to the climax of the main plot, which ultimately leads to the harmonious coexistence of the earth and alien civilization.
