The Three Kingdoms at the End of Han Dynasty: a Time Traveler's Road to Hegemony

Lin Yuan, a graduate of the Department of Modern History, accidentally traveled to Julu in Jizhou after the Yellow Turban War in the late Eastern Han Dynasty. In troubled times, he struggled to survive by relying on modern knowledge: he improved the condition of wounded soldiers with hygiene and epidemic prevention methods, and gained a foothold; he solved the food crisis with the "Three Strategies of Canglin" and won the trust of the powerful Su Shuang. From being in charge of logistics to getting involved in armaments, he improved iron tools, promoted farming, secretly accumulated strength, and fought step by step against the old forces of the Su family. He also met celebrities such as Chen Gong and Tian Feng, and formed a direct line of armed forces. After predicting that Dong Zhuo would be in trouble and Jizhou would become the site of the Fourth War, he advocated moving south to Xuzhou, starting from the county magistrate of Haixi, using the benefits of salt and iron and the strategy of farming to strengthen his power, and gradually separated from the Su family and established himself on his own. After that, he refused Cao Cao's call, joined Yuan to fight against Cao, went south to expand territory in the east of the Yangtze River, rose up during the Battle of Chibi, and took control of Jingnan; then he fought between Cao Cao, Liu, and Sun, seizing the southern part of Yizhou and Jiaozhou. Finally, after Cao Pi usurped the Han Dynasty, he supported the son of Emperor Xian of the Han Dynasty to establish the "Southern Han", which stood in opposition to Wei and Wu. After decades of management, he cultivated political theory internally, implemented the New Deal, expanded territory externally, and waited for opportunities for the Northern Expedition. He took advantage of the change in Gaopingling to establish the foundation of Chang'an. Finally, he went eastward to Tongguan to destroy Wei, swallow up Shu, and conquer Wu, unified the country, changed the Yuan Dynasty to "Chengxia", reestablished order with the imperial examination system and land equalization orders, created a new era of the Later Han Dynasty, and became the "Emperor Taizu Gao" who ended the troubled times. This is an epic story in which time-travelers used their wisdom and foresight to conquer the world and reshape history in the troubled times of the late Han Dynasty.
