Youqi, who was born in war and has no relatives, learned about the Xunyao clan from the mouth of "Red Xunyao Mu Qian" on the day when his only relative (mother) was killed by a bandit demon. He also learned that he was also one of the seven Xunyao "Blue Xunyao".
With the goal of turning back into a human, Youqi follows other Xunyao to collect the "Xunyuan" unique to humans. In the process of collecting and finding fate with other monster hunters, Youqi made many friends and saw another side of this dark world, and the hatred of killing relatives in his heart gradually dissipated.
When Youqi went through the joys and sorrows, and encountered many difficulties and dangers, he collected enough to find fate, and when he could become a human being on the "Night of the Shining Moon" three days later, something unexpected happened. The other six Xun demons, including Mu Qian, were captured by the human emperor who appreciated the magical effects of Xun demon flesh and blood. In order to save Mu Qian and the others, You Qi resolutely gave up the only chance to transform back into a human.
After going through hardships and dangers, Youqi finally rescued Mu Qian and the others.
At this time, Youqi, who was holding the unconscious Mu Qian and escaping with other Xunyao, discovered his feelings for Mu Qian. Finally, after Mu Qian woke up, she finally got the "Youqi's confession" she had been waiting for.
Mu Qian and You Qi are in love with each other. You Qi is willing to give up the opportunity to become a human for Mu Qian. Mu Qian also no longer wants to be a human and ends up staying together as a monster hunter.
Although Mu Qian and You Qi no longer want to be human, they still stay in the world.
