In the year 2578 of the Galactic Calendar, mankind has entered the post-hegemony era in which the stars are fragmented. Alien incidents occur frequently and rumors continue among various forces. Space detective Lu Hao and his alien partner Fika Lyle team up with a group of strange companions to uncover the truth about the aliens in the universe hidden behind disappearances and strange stories. During the journey to trace the "origin of the alien", he was involved in many inter-galactic struggles, misunderstandings and farces. Under the collision of confrontation, cooperation and continuous extension with the Galaxy Alien Authority, misunderstandings, prejudices, humor and growth among the stars were intertwined. In the end, Lu Hao's team joined hands with the aliens to dismantle the biggest conspiracy in the universe - the "Assimilation Plan", defend the coexistence of all races, and find their true connection with the universe.
