Reincarnated As a Ship Girl in a Post-apocalyptic World

Regarding being reincarnated as a ship girl in a post-apocalyptic world: (Note before reading: The system in this story is merely a tool for the protagonist; the protagonist is not a puppet! Also, the protagonist will never get married!) A ship girl in a post-apocalyptic world, a typical otaku like Admiral Liu Yuzhang, one day unsurprisingly transmigrated yet again! Eh! Transmigrating into a ship girl is one thing, but why was I thrown into the apocalypse? And this... Okay, the system is pretty good~_~ But this incredibly ordinary transmigration became incredibly ordinary, riddled with errors. (Book club created! 1154215122)
