Liu Xin, an engineering office worker in the 21st century, accidentally traveled through time and became Zhu Youxiao, the Emperor of the Ming Dynasty. From the beginning, he was faced with a mess of internal and external troubles: the treasury was empty, the party struggle was fierce, and the future money was eyeing. He decided to use his modern knowledge and vision to change his destiny and restore the glory of the Ming Dynasty. He started with glass manufacturing, quickly accumulated wealth and filled the national treasury, then formed a new army, trained firearms troops, and improved the army's combat effectiveness. At the same time, he secretly supported the Donglin Party members and cleverly exploited the conflicts among the eunuch groups to gradually disintegrate Wei Zhongxian's power and take power back into his hands. In the Liaodong battlefield, he used good generals such as Sun Chengzong and Yuan Chonghuan to stabilize the defense line, and used later artillery tactics to severely damage the Jin army and temporarily resolve the threat from the north. In order to completely solve the financial problem, he vigorously developed maritime trade, followed the example of the West in establishing joint-stock companies, and encouraged the development of private capital. However, Emperor Tianqi's series of reforms touched the cake of vested interest groups, who colluded with Hou Jin and set off a rebellion.
