Phobos' position in the entire extraterrestrial system of the Blue Star was that it was an emergency base that was mainly military. It was mainly responsible for the transit of communication with the Moon, as well as military support and integrated dispatch to Mars.
Nearly 30,000 elite students surged into the Phobos' base. The logistical pressure on the Phobos was extremely great. Even though Phobos had already built an extremely advanced water-circulation collection system and a three-dimensional bioecological proliferation area, the scale was still limited.
In fact, from the beginning of the design to the ongoing construction, the position of Phobos had always been a transitional base.
