In the last years of Tianbao in the Tang Dynasty, undercurrents surged under the prosperous age. The emperor is dying, and the position of heir apparent is still pending.
The sixth son of the emperor, Li Jin, whose biological mother died young, was frail and sick, and lived with ancient books all day long. He had no sense of presence in Chang'an City. He was a "sick man" prince who could be bullied by everyone.
However, no one knows what kind of ambition and resourcefulness are hidden behind his seemingly weak eyes. While his brothers were vying for power in the court, he quietly weaved a huge web in his own small area.
When everyone regards him as an abandoned piece on the chessboard, he wants to hold his hand, overturn the world, and aspire for the supreme throne. In this country, it is still unclear who will win.
