In the grand world of "Divine Seal Throne", the forbidden love between Bai Lingxuan and Feng Xiu gave birth to Bai Yue, a special existence with demon blood. When Bai Lingxuan sensed the bloodline of the demon clan in Bai Yue's body, his world collapsed instantly, because he realized that Feng Xiu, whom he loved deeply, was actually a member of the demon clan. In order to protect their love crystallization, Bai Lingxuan did whatever it took to purify the demon bloodline for Bai Yue with his own blood. However, this process caused irreversible damage to Bai Yue, leaving her physically weak and unable to cultivate.
After paying a huge price, Bai Lingxuan fell due to excessive blood loss, leaving the young Bai Yue to grow up alone in the priest's temple. However, how could Feng Xiu's Demon Dragon Clan bloodline be so easy to purify? As he grew older, the Demon Dragon Clan bloodline in Bai Yue's body gradually awakened, and at the same time, Feng Xiu was also looking for his missing wife everywhere in the Holy Demon Continent.
When Kaede Xiu accidentally discovered Bai Yue, who had the same bloodline as him, he was shocked. Hidden aura came to the holy city, and seeing Bai Yue's face that was exactly the same as his wife, Feng Xiu was sure that this was his daughter. However, Long Xingyu's company made it impossible for Feng Xiu to approach Bai Yue. Although he had enough strength to deal with Long Xingyu, out of love for his daughter, he chose to leave quietly.
Under Feng Xiu's careful arrangement, Bai Yue finally learned the secret of her life experience. However, due to her deep relationship with Long Xingyu, she was always reluctant to leave. In order to let her daughter return to herself, Feng Xiu returned to the demon clan and carefully planned a campaign against the exorcism pass. In this battle, the Demon Hunting Regiment became the only force capable of fighting against the Demon God Pillar, forcing Long Xingyu and his companions to run to the exorcism level.
Taking advantage of Long Xingyu's absence, Feng Xiu sent his men to infiltrate the Holy City to take Bai Yue back to the Demon Clan. When she felt that her daughter had returned to the Demon Emperor Palace safely, Feng Xiu personally went to the Exorcism Pass to meet the son-in-law. That's why the people of Demon Fall were only slightly damaged in that blow - Kaede Xiu never intended to actually invade the Exorcism Level. He sacrificed the three demon gods to make Long Xingyu leave Baiyue temporarily.
When Long Xingyu returned to the Holy City tiredly, he found that Bai Yue had disappeared, and his heart was filled with endless pain and confusion. He wandered through the empty temple, searching for the familiar figure, but felt nothing but the cold air and the endless silence. The disappearance of the white moon was like losing the sunshine of his life to him, and his world was plunged into darkness.
In this process, Long Xingyu deeply experienced the pain and helplessness of losing his lover. He began to reflect on his past and future, thinking about how to continue in this unknown and dangerous world. In the process, he gradually understands his mission and responsibilities and decides to embark on a path full of hardships in order to find Hakutsuki and reveal the truth.
In the end, after going through countless trials and challenges, Long Xingyu finally revealed Fengxiu's conspiracy and successfully rescued Bai Yue. In the process, he not only saved his own love, but also the fate of the whole world. And Bai Yue finally found her home and true love after experiencing the revelation of her life experience and the struggle of family affection. She and Long Xingyu work together to face the challenges and difficulties of the future and create their own happiness and legend together.
