The No. 223 resource planet in the West Wind Sector in the Third Battle Area in the Imperium of True Human Beings had an extremely harsh environment without an atmosphere.
The West Wind Sector was a small world with a diameter of thirty billion kilometers. The star here was still in the adolescent phase soon after birth. As a result, the seven planets around the star were all seriously torn by the drastic changes of gravitational forces and could not form a dense atmosphere. So, there was not a single habitable planet.
The ever-changing gravitational and tectonic movements, as well as the material exchanges when the meteorites hit the planets, endowed quite a few satellites of the West Wind Sector with abundant rare metals and crystals.
The West Wind Sector was the remotest world in the Third Battle Area, and the No. 223 resource planet was the remotest celestial body in the West Wind Sector.
