On the day of the late emperor's death, the imperial concubine Su Wantang used modern military means to seize the imperial army and the tiger talisman, and then helped Xiao Mingwei, the abandoned princess of the cold palace, to the dragon throne. Old ministers force the palace, favorite concubines plot rebellion, and relatives assassinate—the court is full of murderous intent. Su Wantang used thunderous means to suppress the chaos, but found that there was a deep conspiracy hidden under the empress's submissive mask. The commander of the Forbidden Army, Xie Xuance, gradually discovered the truth of the imperial edict. The northern general Murong Yan held a heavy army and watched with eager eyes. A game about power and trust began in blood and fire.
