Su Qian, a top student in the Department of Modern Psychology, accidentally traveled to the ancient times where powerful people were fighting. When she first arrived, she discovered that she actually had the ability to read minds, and could penetrate into other people's deepest thoughts just by touching them. With this ability, she can protect herself in the back house where there are undercurrents of power, and she is also involved in court affairs. She relies on her ability to read minds - but she is constantly struggling in the relationship between herself and others. Along with the struggle for power, the test of family ties, the fetters of friendship, and the throbbing of love, Su Qian gradually understood the way "people's hearts are unpredictable". After experiencing various hardships, she went from simply protecting herself to actively helping others, and finally achieved self-salvation, which also affected the trend of the entire era.
