At the same time, the [Shengshi Divine Calculation System] was accidentally activated.
He jumped from a 'problem prince' to a 'star prince'. His father, Emperor Zhu Yuanzhang, was reluctant to leave him to join the feudal vassal, so he stayed in the capital as the emperor's master.
Suddenly one day, the prince's fortune teller announced his intention to rebel against the Ming Dynasty, causing an uproar throughout the country.
After Zhu Yuanzhang heard the news, he offered to give up his throne. His fourth brother Zhu Di refused to accept it, raised an army to rebel, and died in the rebellion. After ascending the throne, Emperor Zhu Gui of the Ming Dynasty launched a massive Northern Expedition and completely defeated the Northern Yuan Dynasty.
