Feng Lixue has been waiting outside the mountain gate. Poyun learned from the disciples of the mountain that today is Mo Xiao's successor to the head. He told Feng Lixue that Feng Lixue showed a calm smile, knowing that this is Mo Xiao's mission.When Mo Xiao had just succeeded as the head of the sect, news came from outside that the demon poison, a disciple of the Immortal Sect who had been poisoned in Fengdu City, had relapsed and everyone could not rescue him. Feng Lixue stood up and said that she could detoxify and was willing to help the Immortal Sect eliminate poison, but hoped to return the Tianxing Seal to her and let her reopen the Tianxing Sect.Yuan Beichen promised to consider it carefully, and then Mo Xiao took everyone to Fengdu City.

After learning about Feng Lixue's behavior, Chongguang praised it very much, thinking that this was his disciple and could go to Shushan to ask for the seal of the sky on such an important day in the Immortal Sect. However, if Feng Lixue successfully gained the trust of the Immortal Sect, Chongguang felt that things would become much easier.

Mo Xiao, Feng Lixue, Xie Lingyun and Murong Jing came to Fengdu City together. Feng Lixue and Murong Jing said a lot, and Mo Xiao followed behind him kept silent. Murong Jing realized that Mo Xiao had been different since he came back, especially after Feng Lixue went up the mountain. Xie Lingyun knew that everything was because of Feng Lixue.

After Mo Xiao stayed in the inn, Murong Jing and Xie Lingyun came to Feng Lixue's residence to visit her, and wanted to know what Feng Lixue's idea could use to eliminate poison gas. Feng Lixue did not say it, but said that she would appear on time to help Mo Xiao remove poison. At the same time, Feng Lixue also hoped that the two would not always come to visit, for fear of being misunderstood by the outside world and colluding with evil demons and heretics. Murong Jing didn't mind at all. After experiencing those things, they had already become friends, not to mention that Feng Lixue has broken away from the Demon Sect, so there is no need to worry about it.Murong Jing also wanted to tell Feng Lixue and Moxiao's efforts to her, but was stopped by Xie Lingyun. Xie Lingyun hoped that they would solve the matter between Feng Lixue and Moxiao by themselves.

On the way back, Xie Lingyun and Murong Jing saw the Poison Lady Hongyue also came to Fengdu City. They were worried that something would happen and hurried back and told Mo Xiao that Mo Xiao had just learned from Hualang that the people in Fengdu City were poisoned because the Demon Sect’s Seven Caves and Nine You did it on purpose.Mo Xiao also guessed that Xie Lingyun and Murong Jing went to Feng Lixue and asked the two about Feng Lixue's plans. When he learned that Feng Lixue had not said the method, Mo Xiao was a little worried.

That night, Mo Xiao secretly went out of Feng Lixue's window to see her, and knew that Feng Lixue had chosen the most difficult road, but she did not hesitate and would protect Feng Lixue's safety. When Mo Xiao was moved, the guardian sand on his wrist stinged, Mo Xiao hurriedly left, Feng Lixue heard the sound and walked out and found a windmill on the windowsill. She knew that Mo Xiao had come.

Lu Jianchuan secretly practiced the soul-crossing spell and transferred his toxins to a rabbit. It happened to be seen by Murong Changfeng. Murong Changfeng blamed Lu Jianchuan for secretly practicing the forbidden technique. Lu Jianchuan begged Murong Changfeng not to tell him, and he would serve Murong Changfeng in the future. Murong Changfeng agreed to think of his difficulties, but did not forget to remind Lu Jianchuan to protect the law when Moxiao was used to remove poison. He might be found that his toxins had not been removed.

A zither girl who claimed to be Ling Xiang found Lu Jianchuan, hoping that Lu Jianchuan could help arrange several of her friends to enter the altar to exorcise the demonic energy. Lu Jianchuan learned that Ling Xiang’s friends were evil demons and heretics immediately refused, but Ling Xiang threatened Lu Jianchuan secretly practiced the soul-crossing spell. Lu Jianchuan had no choice but to agree, and Ling Xiang took the token between Lu Jianchuan's waist.

Hongyue had love with Haotian during the Valley of Love. Now that the demon poison has not been eliminated, they all remember everything about the Valley of Love. Therefore, they came to Haotian specifically to leave, hoping that Haotian could leave with him. However, Haotian had already made a marriage contract with Yueyao and was unwilling to mention everything about the Valley of Love. They persuaded Hongyue to leave quickly, but Hongyue insisted on not leaving and insisted on disrupting all this. Haotian saw the people from the Immortal Sect coming over and left Hongyue.But at this time, a maid came to Hongyue and claimed that she could help Hongyue achieve her wish. The maid took Hongyue to a room, which was Lingxiang, as well as the Lord of Biqiong Island and the Lord of Changshou Valley. They all hoped to go to the altar to remove poison, but Hongyue had a way to restrain the poison gas and was unwilling to go. Lingxiang used Haotian as a bargaining chip, and then she persuaded Yuehong to agree to go to the altar together.

Feng Lixue and Poyun came to the altar as scheduled. Feng Lixue asked Poyun to watch from a distance, but he must not interfere.Mo Xiao came over and whispered to Feng Lixue not to show off and believe that he is there in everything. Feng Lixue nodded slightly.

Feng Lixue and Mo Xiao sat in the center of the altar to activate the magic array. The disciples of the Immortal Sect were all sitting around. All the poisoned Immortal Sect disciples released black air all over their bodies, and their bodies were in unbearable pain. Lu Jianchuan gradually showed signs of poisoning, but she forced herself to restrain her, Hongyue suddenly tried to break through the magic array and took Haotian away, which caused Feng Lixue to be injured. The demonic energy began to scatter. Mo Xiao immediately used the barrier to control the demonic energy to not dissipate.

Xie Lingyun and Murong Ce also came to help. Hongyue wanted to crawl towards Haotian and take him away. Yue Yao happened to come over and stab Hongyue to death with a sword, scolding him for daring to break into the altar.Feng Lixue saw that the formation was about to be destroyed, and the demonic energy was about to rush out. Feng Lixue used his body as a container to suck all the demonic energy into his body. Chongguang felt Feng Lixue's pain. Poyunyan saw Feng Lixue's pain in pain and rushed over to take him away. Mo Xiao and others were busy rescuing the disciples of the Immortal Sect and could not chase him.But the poisoned immortal disciples lost their lives one by one, and Mo Xiao burst into tears.

Poyun and Gu Bai watched Feng Lixue fall into a coma when they were injured and were planning to find some magic weapons to help eliminate the poison gas, leaving Cang Cang alone to take care of Feng Lixue. At this time, Chongguang came and fainted Cang Cang. Looking at Feng Lixue's unconsciousness, Chongguang felt distressed, cut his wrist and dripped his blood into Feng Lixue's mouth.

When he found that there were people from the Demon Sect infiltrated, Lu Jianchuan pointed out that Feng Lixue pretended to exorcise the demon, but in fact, he let the people from the Demon Sect infiltrate and destroy the exorcism, causing so many people to die. Mo Xiao wanted to go to Tianxing Mansion to investigate clearly, but was stopped by Xie Lingyun. Now Feng Lixue can no longer explain clearly. If Mo Xiao mixes it with it, it will be even more difficult to explain, Mo Xiao had to take everyone back to Shushan first.

After Feng Lixue woke up, she found that she was fine. Gu Bai and Poyun found something to come over and felt relieved when they saw that Feng Lixue was fine. Feng Lixue asked about the situation in the altar. Poyun thought that Feng Lixue had absorbed the demonic energy with his body, and everyone should be fine. Feng Lixue smiled.
