In the interstellar ABO world, Lu Lin, the top Alpha commander, was forced into a political marriage with Lin Su, a Beta second lieutenant who was judged as "waste". Everyone was waiting to see the joke, but they didn't know that Lin Su was a "civilized observer" from a higher-dimensional civilization. In his eyes, there was no gender, only tasks. And his final mission report will determine the survival of this galaxy.
The idea: an interstellar marriage with ulterior motives, a dimensionality reduction observer disguised as a loser, and an imperial murderer with a heavy army. Under the curtain of marriage, the ultimate game about the survival of civilization begins.
