In 189 AD, the Han Dynasty collapsed and the world was about to be in chaos. Chen Yan, an ordinary Yulin Lang in Luoyang, accidentally rescued the fleeing young emperor Liu Bian and was involved in the torrent of history. From the beacon smoke of Luoyang to the decisive battle of Guandu, from the fire of Chibi to the original autumn wind of Wuzhang, he witnessed the rise and fall of heroes, and personally experienced the contest of power and the choices of human nature. This is not a legend of time travellers, but a story of how ordinary people find morality, loyalty and the meaning of survival in troubled times. As the wheel of history rolls forward, individual destiny is like a drop in the ocean. Should we go with the flow or go against the current? "Across the Sea" depicts the scrolls of the Three Kingdoms with delicate brushstrokes, exploring how ordinary people maintain their true intentions amidst the great changes of the times, as well as the joys and sorrows that have not been recorded in history books.
