Lin Moyan, a modern history and military enthusiast, stayed up late and died suddenly and traveled back to the Ming Dynasty, the 16th year of Chongzhen's reign, as Zhu Cixiang, the crown prince of the Ming Dynasty. With vague historical memories and modern physical and chemical knowledge in hand, relying on his status as prince, he first made the first pot of gold by burning glass, then researched flintlock guns, improved artillery, and trained a new type of army. Yu turned the tide in the battle to defend the capital. The regent supervised the country's purge of traitors and promoted the New Deal. He led an army of firearms to defeat the Eight Banners and pacify the rogue bandits. Jiange Wuyuan promoted science and technology, promoted industry and commerce, expanded navigation, conquered Japan, and colonized overseas, eventually transforming the Ming Dynasty into a steel emperor that spanned the world. He also grew from a late prince to a Qiming emperor who ushered in a new era. Two strange women, Xu Wanying and Chen Yuanyuan, were always by his side, creating a legend together.
