The Ming Dynasty's Greatest Scourge Is Actually Our Son?

He transmigrates to the Hongwu era of the Ming Dynasty and becomes a legitimate son of the Zhu family: the sixth son, Zhu Kai, younger brother to Zhu Biao and Zhu Di! The civil officials oppose the policy of enfeoffing princes to defend the realm. With no other choice, Zhu Yuanzhang sends sixteen-year-old Prince Ying, Zhu Kai, to govern his fief as a test case! Two years later, Zhu Yuanzhang and Empress Ma bring Zhu Biao and Zhu Di to inspect Zhu Kai's fief and assess his achievements. But the scenes before their eyes leave Zhu Yuanzhang utterly stunned! A peasant woman by the roadside: “His Highness Prince Ying bought all my land and told us to grow some profitable crops for him!” Old Zhu: “That rebellious brat dares to seize the people's farmland and delay spring planting?!” A shopkeeper on the street: “His Highness Prince Ying opened some kind of ‘Heavenly Something’ club... It's full of foreign beauties!” Old Zhu: “A prince of the Ming Dynasty running such a filthy establishment? He's disgracing the royal family!” A Jinyiwei spy: “His Highness Prince Ying has secretly built a fortified city, trained a new army, bred warhorses, supervised the construction of warships, and stockpiled vast quantities of grain, armor, and weapons!” Old Zhu is horrified. Is this little sixth son actually planning a rebellion?! The Ming Dynasty's biggest menace is actually my son?! But the next moment... Empress Ma: “Chongba, Kai'er has miracle seeds that yield six thousand jin per mu. They can end famine throughout the Ming Dynasty!” Zhu Di: “Father, Sixth Brother wiped out the wokou pirates!” Zhu Biao: “Father, Sixth Brother's tax reform and Single Whip Law are both excellent state policies!” Old Zhu sighs helplessly. “You brat, what exactly are you trying to do?” Zhu Kai smiles faintly. “Your son only wants every place touched by the sun and moon to become Ming territory!”
