It's quite obvious that the Kyushu Guard Transport Battleship stolen from the Kyushu Black Prison is no longer reliable and cannot be used again...
On one hand, the deformed cabin door has yet to be repaired, and the maintenance crew sent by Zhao Sansheng is simply dragging their feet.
On the other hand, Zhao Sansheng just pretended to say something about preventing others from seeing it and causing trouble, making the workers open the automatic dome of this Star Dock, encapsulating the Starship like a birdcage.
If this dome isn't opened, even if the Starship were forcibly launched, it would likely incur further damage...
But it doesn't matter, if this Starship can't be used, we'll just hijack another one.
This place is an Interstellar Station beside the main interstellar route of this Star Domain, specially providing supplies and maintenance for passing merchant ships. There are endless Starships here.
