The Three Kingdoms Are Boundless

-Protagonist: Chen Yan, also known as Ziyuan, is a fictional character who was originally a poor scholar from Qu County, Donghai County. He was accidentally involved in the undercurrent of the struggle for maritime power in the late Han Dynasty due to the "fragment of sea charts" recorded in ancient books handed down from his family. He possesses both worldly wisdom and navigational strategy. He was dormant in the early days, but later relied on his knowledge of the ocean to carve out a path of power connecting the mainland and overseas in troubled times. ​ -Core conflict: In addition to the main line of Wei, Shu and Wu competing in the Central Plains, a sub-line of "sea power game" is introduced - Yuan Shao/Cao Cao's forces in the north are trying to control the Bohai Sea and Yellow Sea routes to connect Liaodong; Sun Quan's group in Jiangdong is deeply involved in the Yangtze River Estuary and the East China Sea; Jiaozhou in the south The Shixie family monopolized trade in the South China Sea; while Chen Yan used the "Fragments of Sea Charts" as a guide to explore unknown sea areas (such as the Japanese Islands and Southeast Asian Islands), trying to establish an independent "sea country" force in the cracks between all parties and balance the pattern of the mainland and the ocean. ​ -Era background: Starting from the eve of the Yellow Turban Rebellion (AD 184), it covers key nodes such as Dong Zhuo's chaos, the separatist regime, the Battle of Chibi, and the three-part world. It also intersperses the collision and integration of overseas civilizations (such as Funan, the Japanese Kingdom, and the Roman caravan).
