After the Interstellar Fortress Transformation Factory was completed, Du You immediately put it into use. He directly located a suitable planet in the starry sky and then dragged the factory over to conduct manufacturing on-site.
Du You chose a metal planet; theoretically, this type of planet is the best.
After all, being composed of metal, it's inherently stronger. The downside is its excessive mass, which results in longer acceleration or deceleration times. However, the advantage is also clear—it has greater tolerance and can endure higher speeds.
Overall, when moving the interstellar fortress over long distances, these metal planets have faster travel speeds and higher mobility. Moreover, due to their larger mass, the firepower of the Star Compression Cannon derived from them is greater.
