The heroine (Liu Li): Cowardly and submissive in the early stage, cold and tough in the later stage. Possessing the rare "glazed pure body" (covered in the early stage), after awakening, he opens the "ancient eyes" (can see through illusions and gain insight into the origin).
· Master (Immortal Yuheng): Cold and ascetic, with profound cultivation. Because Bai Yueguang couldn't get what he wanted, he found a similar heroine as his emotional sustenance. He was extremely selfish and paranoid.
· Senior Brother/Demon Lord (Cangming): The master's first disciple is actually of the blood of the demon clan. Violent and arrogant, he has defended the heroine many times because her eyes resemble white moonlight (actually she is also a substitute), and is extremely possessive.
· Senior Sister Bai Yueguang (Fairy Qingyao): She has a cold appearance and is known as the light of the righteous path. In fact, he is jealous and selfish in his heart, has a flawed conscience, and regards the heroine as a thorn in his side.
· True male protagonist (Demon King/Sword Master Li Ye): He has a mysterious identity (can be disguised as a casual cultivator or a demon in the early stage) and is powerful. He is the only person who can see the heroine's soul through his eyes, appreciate her tenacity, and give her respect and help.
