An inexplicable field trip to the Bering Strait leaves the protagonist, Chen Yang, helpless as he is submerged in water. After being rescued by a group of girls who call themselves the Yangyan family, Chen Yang assumes they simply live in an isolated place with no connection to the outside world. He decides to start a new life there, only to discover that he and these girls actually belong to two completely separate worlds. The girls who call themselves the Yangyan family are, in fact, the Yangyan-class destroyers that military enthusiast Chen Yang once knew so well...
Girls, or warships? That's right, ship girls...
Now that the protagonist knows the truth, what will he do in this other world, on its unfamiliar horizons?
(Obviously, he's going aboard! Damn it! I'm an author with plenty of integrity!)
