The novel tells the story of Seraphina, a demon who is tired of the strife in hell and chooses to live in seclusion in the world. She is a top agent of the "Aegis Order", a secret organization that eliminates all supernatural threats in the world. From being chased and hunted by fate, to being forced to join forces because of a common enemy, she finally uncovers a shocking conspiracy between angels and demons that spans thousands of years. In this turmoil that affects the three worlds, they cross races and beliefs to protect each other and the order of the world.
1. Strong setting contrast: the female protagonist is an "atypical" demon who longs to live a peaceful life, and is a psychiatrist who heals people's hearts; the male protagonist is an iron-blooded demon hunter who believes that "those who are not of my race will have different hearts." The two form an extreme contrast in occupation, identity, and camp, and are full of dramatic tension.
2. Old enemies become lovers: The classic "love and kill" and "cat-and-mouse game" start. As the plot progresses, the two people fight side by side again and again, from testing and using each other to gradually understanding and trusting each other, and finally developing into forbidden love, which is extremely emotional.
3. Group portraits and world view: The story not only focuses on the male and female protagonists, but also depicts a complete supernatural world hidden under the modern city, including fallen angels, conservative werewolf tribes, neutral magic council and other camps, building a grand and rigorous Western magical world view.
4. Growth without golden fingers: The heroine's power is the inherent ability of her demon blood, but when used, it will bring huge side effects. Her growth does not rely on plug-ins, but on how to control her own power, stick to her true heart, and achieve self-reconciliation and redemption.
