In the middle of Earth's outer space, a huge piece of factory land was being rapidly developed. The factory was basically a module stitch — easy to disassemble, simple to install. Most of the parts were moved from Space City in the Barnard Star System. With that as their process, it only took only two months or so and the factory already looked spectacular. It covered over tens of thousands of square kilometers and was visible to the naked eye from millions of kilometers away on Earth.
Compared to building a factory on the planet's surface, the Space Factory was undoubtedly far more advantageous. This was especially so for certain types of gigantic machinery with a huge mass or even a highly sensitive and precise instruments. Space was a naturally dust-free, zero-gravity environment that would more often than not, reduce the possibility of trouble and greatly reduce the technical difficulty of such an endeavor on Earth.
