In 210 BC, Qin Shihuang died in a sand dune. Zhao Gao and Li Simi did not announce the funeral, but tampered with the imperial edict, bestowed upon the deceased son Fusu, and established Hu Hai as emperor. A conspiracy that could tear apart the Great Qin Empire was quietly closing its net in the many palaces of Xianyang City.
Outside Xianyang City, Zhao An, a low-level coolie who didn't even have household registration, accidentally broke into this huge secret because of a promise he made six years ago and a bronze dagger of unknown origin.
He has no soldiers, no power, no backing. He only has a picked-up life and a borrowed old horse.
From the dirtiest Liuye Lane in Xianyang City to the cold military barracks walls of Shangjun; from the ants stepped on by everyone to the key piece that controls the world's chess game - Zhao An has only one thing to do:
Before Zhao Gao's false edict was delivered, the truth was delivered to Prince Fusu.
What he wants to change is not only the trend of an era, but also the iron law that has existed for thousands of years: "People at the bottom cannot speak about world affairs."
The wind rises from the dust in Xianyang, and the fire rises from the building that is about to collapse. One person's journey north determines the survival of an empire.
