The Taoist genius Yun Miao enters the world to experience human feelings in order to practice "asking the heart". On the wedding day of King Jin, the side concubine Lin Qingmu mistakenly identified Yun Miao as the main concubine Zhou, and made trouble for her in public. King Yu Heng of Jin knew her identity but deliberately condoned her. At the critical moment, the emperor appeared, revealed the identity of Yunmiao's imperial master, and severely punished Lin's father and daughter. Yu Heng has been obsessed with Yun Miao for five years. He used evil things in the north to lure her into the situation. He raised troops and forced the palace just to seek her favor. In the end, he became a demon and committed suicide. After Yu Heng experienced the world, he gradually understood the warmth and warmth of human nature and stayed in the world.
