Ming Dynasty Calculates the Sea

First review! ! The sisters who are familiar with the maritime literature of the Ming Dynasty are directly locked into "The Ocean of the Ming Dynasty"! ! Who knows! ! Finally, there is a book that makes Zheng He's voyages to the West feel epic! The longitude and latitude optical network in the magnetic storm, the foreshadowing of the Yin Pearl in the deep sea, and the decryption of the sea chart runes give me goosebumps every time I watch it! The male protagonist uses arithmetic to break the situation, the female protagonist bears the fate of her blood, and the trio is both hot and addictive. The plot line and the navigation line run parallel. The details are so solid that I checked the information. If no one recommends the unpopular treasure, it will make me cry!
