Su Zhining, a modern working woman, accidentally traveled through time and became a concubine in the Duke's palace. She was in dire straits but unexpectedly awakened to the power of "mind reading". I thought I could live a stable life with this, but undercurrents surged in the prime minister's house. The concubine's frame-up, the aunt's harsh accusation, the foreign invasion and intrigues, and the emotional entanglements followed one after another. Su Zhining relied on her mind-reading skills to make her way step by step, fighting her way out of the power struggle in the house, and was involved in a larger palace undercurrent and world chaos. Sharing hardships with the cold and powerful minister Shen Yao, and emotionally wrestling with his childhood sweetheart Li Yixuan, truth and lies, choices and decisions are repeatedly intertwined. In the life-and-death tests and games of human nature, Su Zhining not only reversed her destiny, but also gained insight into the life code of "knowing people's hearts but it is difficult to know one's own heart", and finally wrote her own legend with great wisdom and true feelings.
