Bai Ling, the reincarnation of the Moon Goddess, is the noble little princess of Qingqiu. Raised in the lap of luxury, she falls in love with her junior fellow disciple, Long Tianyou, as they spend their days together. When he suffers a cultivation deviation, she even gives him her Golden Core and sacrifices most of her cultivation to save him. But when I return with medicinal ingredients to make medicine for him, I see the teachers and students from Deer Spirit Academy rushing him back for treatment. I also collapse and am carried back to be treated. When I wake, I see my master sitting by my bed. He gives me a stern scolding, and I nod along, agreeing to everything. Suddenly, I remember that my junior fellow disciple was also carried back, and I hurriedly interrupt my master to ask how he is.
I rush to his room and push open the door. The two people inside both turn to look at me. Seeing how close my junior fellow disciple is with that woman, I turn and slam the door behind me. Later, after the woman stirs up trouble between us, Bai Ling and Long Tianyou grow increasingly tense and suspicious of each other, until they no longer trust one another.
Eventually, the two of them are drugged one day. When they wake, no matter how Bai Ling explains herself, Long Tianyou refuses to believe her. In the end, Bai Ling gives birth to twins.
When the demon race invades, Bai Ling breaks the seal that contains the Moon Goddess's power and fights the demons to the death. Only when Long Tianyou sees the woman calling the Demon Lord her big brother does he finally realize the truth...
