After the war between immortals and demons, the saint fell and the immortal world fell into pieces. Seeing that the thousand-year deadline is approaching, the murder weapon will return to the world. In order to protect the peace of the world, the Winged Sect has advanced the admissions examination every five years.
Si Yunuo, the little princess of the Ruiyu Tribe, is a little princess who is loved by thousands of people. She is dissatisfied with the arrangements of her elders and sneaks out of the family under the guise of seclusion to practice to take the exam. However, she never expected to misunderstand and seal a thousand-year-old monster in the first pass.
A man in white clothes descended from the sky to save her from the fire and water. His Highness was fascinated by this handsome senior brother, but he did not expect that this senior brother was actually a spy of the demon clan. Between the elder brother and the senior brother, His Highness finally chose his elder brother.
But if you can let go of someone you fall in love with when you are young and frivolous, this demon spy will eventually live in the heart of His Highness until one day...
A young man who looked somewhat similar to him appeared in the Winged Sect, and those memories in the girl's heart were once again awakened...
