The back half of the spacecraft is inside a giant asteroid, functioning as the information center, a sustainable library, or database of this universe. Compared to troubleshooting, investigation is a more challenging task for me. Discovering something never found before is as difficult as creating a diamond in the empty air. Everywhere in this asteroid is filled with pitted ores that may seem scattered, broken, and, to be honest, ugly at first glance. But soon I realized, a vast amounts of unknown, undefined, but fun information is hidden within every inch of the rough surface. Yes, fun, maybe.
