Zhu Nan was originally a social beast in the 22nd century, but he traveled through time and became the fifth prince of the Ming Dynasty. When he was 8 years old, he risked his life to save Queen Ma and Prince Zhu Biao and became their savior. In the same year, he was diagnosed with brain disease by the imperial physician, and received a "medical certificate" issued by the imperial physician himself. From then on, the fifth prince ran wildly on the road to brain disease. Zhu Biao: "Father, what's wrong, Lao Wu has a brain disease and blew up the Prime Minister's house!" Zhu Yuanzhang: "Well done! Lao Wu's gunpowder is so powerful, it's several times as powerful as Shenjiying's gunpowder!"
