In the fourth century AD, the sky collapsed and the earth split apart in the former Qin Dynasty. King Fu Jian's benevolence left behind the deceased Yan royal family - the young and beautiful Phoenix Murong Chong and the unyielding Princess Qinghe, trapped in a prison in Chang'an. Prime Minister Wang Meng's poisonous plan with a golden sword catalyzed a profound betrayal between uncle and nephew, and pushed Murong Chong into Fu Jian's twisted deep palace cage. The siblings swallowed their humiliation and swore a blood oath on the bed of the powerful minister. However, the hatred between the country's enemies and the family's still lingering, a carefully woven prelude to the fall of the Qin Dynasty was quietly played: poisoning the wise men, bewitching the southern expedition, taking advantage of the chaos to restore the country... When Fu Jian was dying in the Wujiang Mountain Buddhist Temple, the former prisoner Huang Nirvana became the emperor, ending the legend of this overlord with a white silk ribbon. This is an epic of revenge forged by hatred, and an elegy for an empire in which power collapses and the phoenix burns.
