In 996, Lu Chen, a social animal, died suddenly while working overtime. When he opened his eyes, he turned out to be Zheng He, an internal official and eunuch of the Yongle Dynasty! The soul of a modern heavy industry engineer embarked on seven epic voyages to the Western Ocean. While the world was still relying on the sky for food, he had used standardized shipbuilding, cast-iron cannons, and quantified gunpowder to transform treasure ships into crushing-class iron-framed battleships. They severely damaged the four Japanese pirate islands, opened up new territories, discovered the Americas across the Pacific, and used engineering to turn Africa into the granary of the Ming Dynasty—a fleet turned the earth into the backyard of the Ming Dynasty. Is everyone despised? Once the blueprints are laid out, you won't even have time to kneel down. This was the Ming Dynasty's sea power craze and Lu Chen's counterattack.
