I Transmigrated as Zhu Yuanzhang's Imperial Grandson

The protagonist suddenly returns to a previous life and discovers that he is Zhu Di's eldest legitimate son, Zhu Gaochi! According to history, Zhu Di was forced to rebel and steal the throne from his nephew. His eldest legitimate son, Zhu Gaochi, was broad and heavyset, frail and sickly, and spent more than twenty years painstakingly raising military funds for Zhu Di's wars. Zhu Di then turned to his second son and said: “The Heir Apparent is often ill. You should strive to do better.” The protagonist: “...” What a complete sucker. After Zhu Gaochi took the throne, he died of illness and overwork just ten months later. Later generations called him Emperor Renzong of Ming... What a sucker. Back in his previous life, the protagonist works hard to lose weight and get healthy, while also taking it easy. This crown prince business? Whoever wants it can have it. He's done with it. Wouldn't it be nice to become a leisurely prince, with money and free time aplenty? The protagonist looks forward every day to his father starting a rebellion. After being sent to Yingtian Prefecture as a hostage, he meets an old man. The old man is imposing yet kind, and most importantly, he looks exactly like the protagonist's grandfather, who died of illness in the modern world. Thinking of how Zhu Yuanzhang is about to purge the court, leaving a river of blood, the protagonist worries the old man, a low-ranking official in his service, won't escape death either. The protagonist grits his teeth and tries to win him over: “Old sir, the Hongwu Emperor is about to purge the military officers to clear the way for his beloved grandson.” The old man's eyes narrow. The protagonist: “Even Xu Da and Hu Weiyong, who helped him conquer the realm, won't escape death, let alone a low-ranking official like you.” The old man's gaze turns sharp. The protagonist: “Why don't you... consider Prince of Yan Zhu Di?” The old man gives him an unreadable look. “Are you urging me to rebel alongside Prince of Yan?” The protagonist smiles shyly. “Rebellion sounds so unpleasant. We're simply following Heaven's mandate and securing everlasting prosperity.” The protagonist waits for his father to rebel. He waits and waits, but who knew Zhu Di would become crown prince and inherit the throne legitimately, while he himself would become the Imperial Grandson appointed by Zhu Yuanzhang? Zhu Di: “...” The protagonist: “...” The old man smiles faintly, concealing all his accomplishments. “Good grandson, I'm Zhu Yuanzhang. Call me Grandpa, and the throne is yours.” Help, I only wanted to take it easy. How did I suddenly end up becoming emperor?! #EveryDayIUrgeMyFatherToRebel# #AfterBecomingZhuYuanzhangsBelovedGrandsonZhuDiRisesInRankThroughHisSon# Zhu Yuanzhang has lost the crown prince he so carefully trained. He exhausts himself and racks his brains trying to find a successor. His sons are reckless and impulsive, while his grandsons are cowardly and incompetent. Overnight, Zhu Yuanzhang ages ten years. “There is no one to succeed me. My Great Ming is in danger.” Fortunately, while traveling incognito and concealing his identity, he meets a young man. Zhu Yuanzhang weeps with joy. “Heaven has not abandoned my Great Ming! With this young man, Great Ming will prosper forever!” Sun and moon shine together, and the world belongs to Great Ming.
