The deposed prince Xiao Jingheng overthrew the court, stained the dragon robe with blood and disappeared from the world. Three years later, iron hooves suddenly appeared in the north, and red crows attacked at night in the south of the Yangtze River. The former deposed prince returned with a powerful general from a poor family, Xie Zhao, and the poisonous doctor Liu Zhiwei. The powerful Prime Minister Pei Mingzhao and the ambitious lord Zhao Yuncheng surrounded and killed him step by step, while a burned "Tiangong Policy" was quietly rekindling the hearts of the people. When the Emperor is crowned again, he not only wants the throne, but also the Thunder New Age that subverts the thousand-year-old family.
