A modern woman, Guo Yao, accidentally traveled through time and became the Queen of the Han Dynasty, Guo Shengtong. At that time, Liu Xiu was beginning to rule the world, and there were undercurrents of various forces in the court, and disputes continued in the harem due to competition for favor and power struggles. Guo Yao activated the mysterious space system and embarked on a unique journey of cultivating immortality. Since then, his fate has been closely linked to the rise and fall of the Han Dynasty. Yin Lihua's ambitions extend beyond the harem, and she colludes with reactionary forces to usurp the throne through a coup. Guo Yao relied on the intelligence network to gain insight into the conspiracy and presented the evidence to Liu Xiu. Because Liu Xiu had doubts about his feelings for Yin Lihua, Guo Yao cleverly arranged for him to witness the crime. Guo Yao used the power of cultivating immortals and the magic weapon of the system to help Liu Xiu defeat the rebellion and stabilize the court. Liu Xiu re-examined his reliance on Guo Yao, and Guo Yao gained the right to speak politically. The cultivator enters the mysterious trial space, breaks through to the middle stage, and gains stronger magical abilities such as water control and fire control techniques.
