Lin Chen, a polytechnic college student, travels through Yongli for five years, using his knowledge of military industry and agronomy to improve firearms and promote high-yielding crops. He started in Guilin, established a research class, and joined forces with Li Dingguo and other anti-Qing forces to gradually reverse the crisis in the Southern Ming Dynasty. After going through the bloody battle of Blackstone Valley, the Kunming New Deal, and the three-way Northern Expedition, he finally overthrew the Qing Dynasty, established the modern Ming Dynasty, promoted national awakening and rejuvenated the country through science and technology, and completed the epic journey from "reviving the Ming Dynasty" to "revitalizing China."
