Restarting the Great Ming Dynasty

A top student from the 21st century transmigrates as Zhu Cilang, the last crown prince of the Ming dynasty. After fierce battles with Li Zicheng, he retreats to Nanjing with a fortune in tow. That same year, he rallies his forces in Nanjing and launches a northern campaign, leading his army north in an unstoppable advance and capturing the capital. With his army at the borders, he then marches north into Mongolia, routs the Russian invaders, and reaches the shores of Lake Baikal. Years later, Zhu Cilang establishes the Harbin Generalship, governing vast territories stretching north to the Arctic Ocean, west to Mongolia, and east to Sakhalin Island. That same year, Goryeo, Fusang, Nanyue, and other countries submit and pay tribute. Over the next decade or more, he uses modern weapons to conquer cities and expand his territory. He appoints Zheng Zhilong as naval commander and sails south to defeat the Dutch navy. He establishes the Jakarta Generalship, governing most of South and Southeast Asia. He establishes the Americas Generalship, sending the navy to land in the Americas, and establishes the Australia Generalship. He then leads his army all the way to Europe. After several rounds of conflict, the Ming Empire begins to establish a new international order.
