The strongest eldest son of the Ming Dynasty

Zhu Yao, a science PhD, travels back to the late Yuan Dynasty. He toils for over twenty years, clearing land, farming, selling grain, and building roads... eventually becoming one of the wealthiest men in the region. He then discovers he is the son of a monk surnamed Zhu. In the tenth year of the Hongwu reign, he recognizes Zhu Yuanzhang at his grave! He takes Zhu Yuanzhang home, where Zhu Yuanzhang is captivated by the many things in the house, like a country bumpkin entering the city. "Son, what's this?" "That's a road. To get rich, build roads first!" "And this?" "That's a world map. See Australia and America? They're overflowing with resources!" "This is the northern desert, the hiding place of the Yuan remnants. Cattle and sheep roam everywhere, and food is plentiful!" "This is Southeast Asia. The islanders are docile, and they're rich in spices and jewels. Perfect for capturing them as tenant farmers!" "This is the West, filled with barbarian small countries. If they don't submit, we'll fight them. Once they submit, they'll pay tribute, making them worship the Ming Dynasty every year!" "And there are the Japanese pirates of the East. Sooner or later, I'll trample the cherry blossoms with my horse!" Faced with Zhu Yao's eloquent speech, Zhu Yuanzhang's eyes lit up. Sweeping across the land, subjugating the barbarians, spreading the might of the Ming Dynasty throughout the world—what ambition! If all this were achieved, he would surely surpass Qin Shi Huang and Emperor Wu of Han!! Steelmaking, oil extraction… more and more of Zhu Yao's secrets were being revealed!! Everything was ready; Zhu Yao planned a rebellion! When Zhu Yao stepped out of the courtyard that day, he was stunned. Imperial guards stood in a square formation, his father, dressed in a dragon robe, accompanied by Zhu Biao, Zhu Di, and other members of the royal family, along with civil and military officials! "Son, you are the eldest son of the Ming Dynasty. We've decided! We will sweep away the barbarians on all sides! You will be the Emperor of the Ming Dynasty!" "..."
