In the third year of Jianxing's reign, Chen Yan, a graduate student in the Department of Modern History, accidentally traveled to Shuhan and became a minor official in Mianzhu County. At that time, Zhuge Liang was preparing for the southern expedition. The Shu Han Dynasty was experiencing internal and external troubles, and Liu Chan's dark reputation was beginning to appear. Without a systematic golden finger, Chen Yan only relied on the history books in his mind, and first used the strategy of improving the farmland to help the local area have sufficient food and grass, which attracted Zhuge Liang's attention.
After entering the Prime Minister's Office, he repeatedly offered pragmatic strategies: rectifying the grain transportation plank roads to reduce losses, improving ordnance technology to strengthen armaments, and admonishing to stabilize the southern and central tribes by appeasing them instead of suppressing them. After Zhuge Liang died of illness in Wuzhangyuan, Chen Yan blocked Jiang Wei's frequent northern expeditions and instead assisted Liu Chan in recuperating, rectifying the administration, and uniting with Soochow to consolidate the alliance.
Over the past ten years, the Shu Han's national power has gradually grown. Chen Yan led his troops to first capture Liangzhou to accumulate combat power, then broke through Chang'an to open the door to the Central Plains, and finally joined forces with Soochow to conquer Luoyang. In the end, he welcomed Liu Chan into the Central Plains, restored the Han Dynasty's foundation, and ended the Three Kingdoms conflict for nearly a century.
