Kanmu No Hokage Is Born

This is a world where admirals are scarce. Ship girls can invest resources through the builder to build admirals from other worlds. This is how Xia Qiu, the time traveler who has dominated the Naruto world, was created. Ps: The setting of Admiral Dajian in this book comes from a book called Ship Girl that I have read for some time. I thought it was interesting and used it. Please give me your advice on new books. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
