O'Sheain in New York is very ordinary. The only extraordinary thing is that he is a liver emperor and he is not bald.
…………Okay, to be serious, he has a game system, and in the system there is an entire port area of battleships – all of them are young ladies.
However, after Gan Emperor O'Sheen spent several years upgrading all the ladies there to full levels, completed his scientific research and successfully became a boss with a full illustrated book - all the ladies in the port area had their gender changed, and they could even come to reality with consciousness.
In fact, it doesn't matter. After all, O'Shea is not sexist, nor is he a fat nerd who thinks with certain organs. He doesn't even like women. However, O'Sheen is a Lord of the Rings. In order to increase his combat power, he has married dozens of ships in formation, and the dockyard is full of wives——
This is difficult to handle, especially since there are several 120-level wedding ships with yandere attributes in his shipyard.
O'Sheain felt that he had to first consider how to survive before worrying about other things... Such as New York being attacked by aliens.
Note:
1. The protagonist is actually very strong but doesn't realize it.
2. Most battleships regard O'Sheain as a close friend or master. The protagonist originally had no feelings for the battleships beyond friendship and family affection.
3. The cp is undecided, and I personally prefer the company.
4. The gender of ship names that are too feminine will not be changed, such as the female Kitchen Goddess and the female admiral.
