According to Beichen's narration of what happened a thousand years ago, Bai Shuo learned that the fox girl Linglong entered Kunlun, met and fell in love with the saint Rongxian. However, the immortals and demons were fighting endlessly, and their love was not tolerated by the two races, so they simply lived in seclusion and ignored worldly affairs. Suddenly one day, Linglong broke into Kunlun Sect and started a massacre. Rongxian heard the news and rushed over to kill Linglong, then went to Jingyou Mountain and started a massacre.
In order to completely eliminate the resentment, Bai Shuo proposed to stop Linglong and Rongxian from falling in love, but for now she had to accompany Linglong to see Rongxian. Because Linglong planned to use the beauty trap to seduce Rongxian and obtain the snow lotus, Bai Shuo deliberately interrupted the conversation between Linglong and Rongxian at the banquet and made Rongxian interested in him.
At this moment, outside the palace gate, Mu Jiu and Beichen met, and were shocked that each other was sucked into the resentful environment. Linglong came out of the hall and found Mu Jiu, who was particularly attentive to her, interesting. She misunderstood that Rongxian fell in love with Bai Shuo at first sight, which made Fan Yue jealous and rushed into the banquet. As a result, Linglong misunderstood that Bai Shuo and Fan Yue and Mutual affection.
In order to conceal his identity, Fan Yue had to play along. Linglong wanted to fulfill her sister's feelings, so she decided to personally hold Rong Xian back and arrange for Bai Shuo and Fan Yue to steal the snow lotus. Bai Shuo and Fan Yue exchanged secret messages. Fan Yue said that the only way now was to get the snow lotus and complete the mission as soon as possible so that he could bring Linglong back to the fox clan and reduce the possibility of her falling in love with Rong Xian.
On the other side, the elders of Kunlun tied up Beichen, whipped him, and forced them to tell the true intentions of their fox clan. Beichen was feeling miserable right now, unable to express his pain. Mu Jiu was enjoying watching this and even whipped Beichen himself.
When it was getting dark, Rongxian accepted the invitation to have tea with Linglong, and they had a very pleasant conversation. On the other hand, Fan Yue brought Bai Shuo to the snow mountain, dismantled the formation and obtained the snow lotus, but was besieged by Kunlun disciples. When Linglong heard the bell, she realized that the Kunlun disciples had already ambushed in the snow mountain. She angrily rebuked Rongxian, but Rongxian told her that he and Linglong had met once before.
Ten years ago, Rongxian was seriously injured and fainted in Qingling Mountain. Fortunately, Linglong rescued him. Because he was covered in dirt, Linglong naturally could not recognize him today. Rongxian knew that Linglong needed the snow lotus to save the old patriarch, so he took out the snow lotus as a gift. Linglong was shocked and moved by this, and remembered his kindness to her.
Fan Yue did not want to fight with Kunlun's disciples, so he teleported in the realm of resentment. However, he was ultimately unable to stop Linglong and Rongxian from falling in love with each other. The next second, Rongxian's obsession sent the four of them to three years later. Linglong and Rongxian had already married and lived in seclusion. Although they would occasionally quarrel, they loved each other so deeply that they could tolerate any shortcomings and only see each other's advantage. Originally, Bai Shuo and Fan Yue continued to try to separate the two, but under the subtle influence of the two, they began to understand love.
Linglong is pregnant now, but she has not told Rongxian yet. Just when she was about to tell him the good news, Rongxian received news from Kunlun Sect and learned that the sect leader was seriously ill and would not live long. The head of the sect wanted Rongxian to inherit his position, but Rongxian refused. He said that the battle between immortals and demons had lasted for thousands of years and they should coexist peacefully. He was even more unwilling to break his oath to stay with Linglong for the rest of his life.
Seeing Rong Xian's resolute attitude, the head of the sect, together with the elders, controlled Rong Xian and transferred all their spiritual power to him, forcibly tampering with his memory, turning his love for Ling Long into hatred. This scene was seen by Mu Xiaopeng outside the gate. Nine saw it. Because Rongxian was influenced by his memory, he thought that the fox clan was the enemy who killed his parents, so he went to Jingyou Mountain to kill people. Beichen tried to stop him but was seriously injured.
Linglong realized that the fox tribe was in trouble, and before leaving, she told Bai Shuo to cherish the people around him and live a good life with Fan Yue in Wangyou Valley. Linglong then returned to Jingyou Mountain, but was unfortunately stabbed to death by Rongxian. Linglong's blood splashed into Rongxian's eyes, causing Rongxian to regain clarity and memory. When he learned that Linglong was pregnant, he was shocked to realize that he had killed his wife and children with his own hands and was heartbroken.
