In the Dajing Dynasty, the new emperor Xiao Jingyuan ascended the throne for the first time. Inside, he was restrained by powerful ministers and watched by vassal kings. Outside, there were barbarians from the north and chieftains from the south causing chaos. Undercurrents in the court were surging and the country was on the verge of collapse. Everyone thought that the new emperor was alone and helpless, but they didn't know that behind him stood the emperor's younger brother Xiao Jinyu, who had been forgotten by the royal family for many years.
Xiao Jinyu was frail since childhood and was sent to the royal villa to rest and stay away from the disputes in the court. However, he secretly read a lot of books, made friends with talented people, and developed the ability to strategize. When the emperor's brother was in trouble after ascending the throne, he resolutely walked out of the villa and dealt with various forces as an "idle prince".
In the court, he fought with the Confucian scholars and cleared political obstacles for the emperor's brother; on the battlefield, he made suggestions to help the emperor's brother put down internal and external rebellions; in the harem, he discerned the conspiracy and solidified the foundation for the throne for the emperor's brother. He does not seek power, position, or rewards. He only wishes that his imperial brother will live long and that Dajing will be peaceful and peaceful for a long time.
From a marginalized prince who no one cared about to a powerful "behind-the-scenes master", Xiao Jinyu used her resourcefulness and loyalty to write an eternal story of "brothers, friends and brothers". When the imperial power was stable and the world was at peace, he chose to retire and return to his home. Xiao Jinyuan held hands and said to each other: "Brother, this country is half mine and half yours." From then on, the two brothers worked together to build a peaceful and prosperous era.
