When Su Yinwan, the princess of the Kingdom of Forest, was six years old, Su Sheng was seduced by Feng Yu. The two of them broke into the Kingdom of Forest on the Qihuo Festival and took Su Yinwan away. This behavior also alarmed the monster that had been sleeping for a long time - the Demonic Consciousness Beast. Su Yinwan's knight knight and fiancé Ye Xiangchen also followed. Su Sheng once thought it was the Demonic Consciousness Beast brought by Su Yinwan. In order to protect Su Yinwan, Ye Xiangchen reached an agreement with the two. "I'll help you deal with those monsters, but only if I'm the only one who stays with the princess to protect her."
Purpose: The person the princess marries is not necessarily a prince.
