The Xingluo Dynasty was established based on the "mandate of destiny", and the Xinggui Division controlled the destiny of the country. The twins were regarded as "disasters coming to the world". Deep in the Hidden Palace, bronze chains wrap around the bones of the twin princes of the past dynasties; in the Tai Chi Palace, the gilt dragon chairs reflect the blood stains of the Star Orbit Division's "Destiny Engraved". On the night of the late emperor's sudden death, half of the blackened edict fell to the ground. The word "Hidden Palace" tore apart centuries-old lies of the dynasty - the third prince Shen Yan, who had his left eye gouged out, and the prince Xiao Heng who wielded the Ziwei Dragon Pattern Sword. The two brothers, who were predicted by the Star Track Division as "twin disasters", started a life-and-death game about blood, power and truth in front of the dragon bed.
