Psychological counselor Li Wei traveled as the prince's companion and discovered that the "tyrannical prince" in the history books was actually the result of psychological manipulation.
The mastermind behind the scenes planned for ten years to transform the prince into a puppet.
What Li Wei wanted to do was to do this without modern instruments:
- Reverse treatment of the prince who was deeply hypnotized
- Uncover the "psychological assassin" lurking in the East Palace
- In this game of chess, he is both a doctor and a pawn
When he finally cured the prince, he found that he had become the "inner demon" in the eyes of others...
