In 2342, a hundred years after mankind opened the "Stargate Era", it established the "Star Sea Federation" and struggled to survive in the Milky Way. Together with the silicon-based machine race, the insect nest mother race, and the psychic crystal race, they were listed as the "four major interstellar lower civilizations". They were not only competitors for the resources of the dark erosion zone, but also potential prey and hunters under the laws of the dark forest. Above it, there are advanced civilizations that control "dimensionality reduction strikes" and "dimensional weapons". Amid internal and external troubles, the survival of human civilization is in a dilemma, and the choices of each faction are hidden in calculations and selfishness. There is no absolute justice, only differences in stance. As Lin Chen later understood, the so-called "protecting civilization" sometimes needs to step on the bones of the same kind.
