Chen Qing had exceptionally strong hands-on abilities; she was a born Mechanic.
By the time One-eyed arrived with a group of battered soldiers at the factory, Chen Qing had already stripped the submarine's entire hull and was in the process of rewelding it.
The original hull had long been corroded by seawater beyond recognition, and it wouldn't have lasted much longer.
Once the hull ran into problems, even if Chen Qing repaired the inside, it would collapse along with the hull.
The vessel destroyed, the crew perished.

Chen Qing had dug up quite a few rare metals from the pile of trash, and with some advanced lumber, it should hold for another twenty or thirty years.
The premise was, no major damage.
For instance, encountering some sea beast or the like.
