Core settings:
- The heroine Mu Wu: The youngest daughter of the Nine-tailed Fox Clan in Qingqiu. She has been practicing for thousands of years. She is innocent but has a hidden wisdom. She left the mountain privately because of her playfulness. When she first entered the world, she was full of curiosity about everything. She was good at illusions and charms, but she often made things worse because she was not familiar with the world.
- Male protagonist Xie Shengzhao: A great general of the Dajing Dynasty who has made great achievements in the war. He is twenty-five years old, cold and taciturn, decisive in killing, and shoulders the heavy responsibility of protecting the country. He has a desire for peace deep in his heart. Due to years of fighting, he is extremely wary of evil things.
- Story background: During the middle period of the Dajing Dynasty, there were occasional frictions between the border and the territory of the demon clan. The human world was both afraid and curious about the demon clan. The imperial court had a "Demon Suppression Department" that specifically dealt with demons. The relationship between the human and demon worlds was delicate.
Intention: Written out of boredom
