Amid the bitter winds of Mobei in the fourth year of the Yuanshou era, twenty-three-year-old Huo Qubing raised the Xiongnu’s golden crown, unaware that the lanterns of Weiyang Palace had already driven a wedge between his fate and Liu Che’s. When he was twelve, the boy was whipped and branded with vermilion before an ice mirror in Ganquan Palace. He pierced the collarbones of three Xiongnu spies with a repeating crossbow, and the vow he shared over wine with the emperor was steeped in the scent of lychees and blood. At twenty, a tiger tally hidden in a bronze pillar at Bailiang Terrace exposed the secret pact between Empress Dowager Dou and the Xiongnu. Liu Che’s fingertips, stained with balsam juice, branded both power and suspicion onto Huo Qubing’s shoulder. When the golden figure used in the Heaven Sacrifice became a political curse, the bones of warhorses beneath the Qilian Mountains rang in time with the iron cavalry echoing through Weiyang Palace. Amid the flames of Huo Qubing burying prisoners alive, he glimpsed the emperor’s vermilion annotations on a bamboo slip. They had once marked the wine they shared as boys; now they had congealed into a death warrant. Swept along by the tide of history, a hero’s backbone corroded beneath vermilion, while an emperor’s tears seeped into bamboo slips. The boyhood friends who had once been so close became strangers, leaving only blood-red fissures carved into the land of Hexi, an eternal question etched into the earth.
