Ship Girl: My Star Fleet

Wu Fan traveled to a world that was abused by the deep sea. Without a golden finger, he accidentally bound the imaginary number engine, a technological crystallization from a high-dimensional civilization. Find the truth, awaken the ship girls of the past, rebuild the garrison, step by step become the marshal of the federal navy, and lead the human federation to defeat the deep sea fleet and set foot in the starry sky! (A mixed ship B, ship R, and ship C, a somewhat novel and imaginative world of ship girls. Please refer to this book for all settings and rationality.)
