Ming Dynasty: from Emperor Grandson to Global Hegemon

[Soul Transmigration + Dual Souls + Infrastructure Farming + Technology Tree Climbing + Emperor's Grandson + World Domination] When he opened his eyes, the Ming history graduate student returned to Hongwu for fifteen years and became Zhu Yuanzhang's eldest grandson - Zhu Xiongying. Being familiar with history, he started with a certain death situation: he died young at the age of eight, and his father Zhu Biao died of illness two years later. Then, during the Jingnan War, the Ming Dynasty's national fortunes declined like a cliff. Fortunately, the system was bound, but before he could be happy, he discovered that things were not that simple - there was a real eight-year-old child in his body. Two souls share one body, and under the eyes of the most discerning emperor in history, they don't even dare to move their lips. In order to survive, he launched cowpox vaccination, built a national epidemic network, issued banknotes, and promoted military settlements - proving his worth step by step under Zhu Yuanzhang's scrutiny. Many years later, Zhu Yuanzhang climbed to the top of Yingtian City for the last time. The steam armored fleet lined the Yangtze River, and the map of all nations was spread out in front of him. He looked at his grandson who should have died young and asked him what his next step would be. Zhu Xiongying smiled: "No one who is supposed to come can escape."
