In the "Star Era" of the 31st century, humans have colonized more than 200 planets in the Milky Way, but their spheres of influence have been divided by the "three major technological oligarchs" (the "Star Bridge Group" that controls curvature navigation, the "Origin Alliance" that monopolizes gene editing, and the "Intellectual Core Empire" that controls artificial intelligence). The oligarchs use "technical authorization" to squeeze the resources of colonial stars, and the people at the bottom need to "rent" even basic medical nanorobots in installments. There is a "technological generation gap" between the stars - the core star field controls "antimatter energy", and the marginal colonial stars still rely on fossil fuel transformation.
