After being deposed, Su Mingzhao was thrown into the cold palace. In despair, he awakened the [lie detection system], which can see through the lies and emotional colors in other people's words. With this ability, she saw through the hypocrisy of the concubines who came to humiliate her in the cold palace, and uncovered the evil hand behind the poison. Using "truth" as her edge, she started by helping a young palace maid who was wronged and gradually established her own intelligence network. On the surface, she sits in the cold palace, but in fact, she has a clear view of the lies in the harem and even the former dynasty. She uses the information gap to sow discord, disrupt hostile alliances, and lead the emperor to discover the huge conspiracy behind the queen's dethronement. As the system is upgraded, she is able to see through other people's hidden intentions and past secrets. From internal fighting in the palace, to party disputes in the previous government, and even spies from neighboring countries, all lies are invisible to her. In the end, she not only redressed her grievances and returned to the throne, but also became the emperor's indispensable "eye of the truth". With her unique wisdom and cold and harsh methods, she purified both internal and external affairs, firmly established herself in the palace, and became a true uncrowned queen.
