During the Tianbao period, undercurrents surged in Chang'an City. Li Jing, the nephew of the prime minister, caught a glimpse of the hideous acne beneath the surface of the prosperous Tang Dynasty amid the fire and music at the Qujiang Banquet. Overnight, the wealthy family was covered with snow, and the noble prince was reduced to a coolie at the dock. Only an ancestral jade pendant was burned like a brand in a pool of blood.
This jade is both a key and a curse. It allowed Li Jing to see ghosts and hear whispers, and it also led him to a battlefield older than the strife in the court - where the iron hooves of Anshi danced with ancient demonic shadows, and the emperor's dream of immortality was sacrificed to the common people.
From the sacrificial secret cave in Caobang, Yangzhou, to the demon-suppressing site of Nanzhao Miasma; from the mortal flames of the bloody battle in Suiyang, to the indescribable things in the Lishan underground palace. On the road of revenge, Li Jing picked up the fragments of jade pendants scattered all over the world, and also gathered a group of fellow travelers with their own scars: the witch who gave up her oath, the monk who kept silent, the doctor who hid his edge, and the ranger who regretted it.
They finally understood that the enemy was not a powerful official or a demon, but the "chaos" that was about to drag the entire era into the abyss. When the final choice came - to sacrifice one's body to suppress the Demonic Abyss forever, or to spare one's life and watch the world become a purgatory - the young man who had once been well-dressed and well-fed, clenched the jade pendant in his hand that had been stained with blood and wind and frost.
This is a story about how a noble son forged a personal blood feud into a blade that saved the common people when his family and country were about to fall.
