Episode 24 recap: Everyone exerted their efforts to rescue Yao Chen, and Xun'er took over the vital energy for Xiao Yan.

After the battle in the Star Region, it became an undeniable fact that the Soul Hall had risen from the ashes, and the Central Continent once again fell into crisis. Feng Xian summoned the major factions of the Central Continent to discuss jointly mobilizing against the Soul Hall. However, each faction had its own thoughts, leading to disunity and accusations that the Starfall Pavilion was using everyone's strength solely for the purpose of rescuing Yao Chen. Yet, it had been over fifty years since Yao Chen's demise, and it was uncertain whether he was still alive or not, as only members of the Starfall Pavilion claimed so.

The various factions were more concerned with self-preservation and were unwilling to confront the Soul Hall. However, the Starfall Pavilion was determined to stand united and decided to battle the Soul Hall and rescue Yao Chen, even if it meant relying solely on their own strength. Feng Qing'er requested to fight against the Soul Hall, but she was scolded by the Pavilion Master and had her martial arts revoked. Gu Clan's Patriarch summoned Xun'er and handed her the scroll of the Three Profound Changes of Heavenly Flame, revealing to her that Xiao Yan was indeed a descendant of the Xiao Clan, although the Xiao Clan's bloodline had nearly disappeared. He had kept this information from Xun'er to protect Xiao Yan. The Three Profound Changes of Heavenly Flame was a relic of the Xiao Clan and should be returned to Xiao Yan. He sent Xun'er to deliver it personally to Xiao Yan in the Central Continent but instructed her to return promptly since Xun'er, as a clan's future successor, had her own mission to fulfill.

Upon hearing this, Xun'er was overjoyed. Xiao Yan was about to face the Soul Hall, and it was the perfect time to enhance his training with the Three Profound Changes of Heavenly Flame. Xiao Yan knew that time was running out for him, so he used the Bone Spirit Cold Fire to meet with Yao Chen and learned that one of the Soul Hall's divisions was located in the Soul Breaking Mountain Range in the western part of the Central Continent. Feng Xian warned the disciples of the Starfall Pavilion that if they wanted to confront the Soul Hall, they must diligently cultivate their martial arts or quickly master a unique skill.

As Muhou had already reached the Dou Zun level, while they were merely at the level of Dou Wang, Xiao Yan was determined to eliminate the Soul Hall and rescue his master. However, Feng Zun Zhe prohibited him from participating in the operation. Xiao Yan asked why, and Feng Zun Zhe explained that he was affected by a demonic poison spot and couldn't activate his Spirit Fire. If he were to participate, he would not only be ineffective but also become a burden to everyone. Xiao Yan was dissatisfied with this decision but had no choice.

Feng Qing'er also arrived at the Starfall Pavilion and couldn't help but cry upon hearing Feng Xian's words. She believed that now that her martial arts had been revoked by her master, she had become useless and wondered how she could participate in the battle against the Soul Hall. Feng Xian reassured her and presented her with a weapon, the Demon Emperor's Holy Image Bell, which was left behind by Yao Chen and was an ancient martial art technique passed down by the Demon Emperor Clan. If cultivated well, it could create a lifeless zone within a radius of a hundred miles. Feng Qing'er was a descendant of the Demon Emperor Clan, and Mu Qing Luan was a descendant of the Phoenix Clan, making this martial art technique suitable for both of them to cultivate together.

Upon hearing this, Feng Qing'er wiped away her tears and started training with joy, considering it a priceless treasure. Xiao Yi Xian also activated her Pure Yang Qi to stimulate the Nihility Poison Body and enhance her Dou Qi. Meanwhile, Xiao Yan remained bored and listless in his room. When he heard someone enter, he thought it was Xiao Lazi bringing him food and without even looking, he asked them to leave it there.

Xun'er came in, and when Xiao Yan heard her voice, he turned his head and saw that it was indeed Xun'er. He excitedly ran over and lifted her high in the air. He learned from Xun'er that she had brought him the second volume of the Three Profound Changes of Heavenly Flame. However, Xiao Yan did not show the expected excitement, and Xun'er realized that Xiao Yan must have something on his mind. She came to find Xiao Yi Xian and asked if she had always had feelings for Xiao Yan and what kind of person Xiao Yan was in her heart. Xiao Yi Xian did not shy away from expressing her feelings for Xiao Yan, but she believed that there was nothing wrong with liking someone and that she would always use her life, protected by Xiao, to repay his kindness.

Xun'er was deeply moved and also gave Xiao Yi Xian a book called the "Heavenly Poison Compendium." From Xiao Yi Xian, Xun'er learned about the demonic poison spot on Xiao Yan's body. Xun'er hurriedly went to stop Xiao Yan, but it was too late as Xiao Yan had already begun training in the Three Profound Changes of Heavenly Flame. He wanted to fully utilize the third-level battle technique of the Three Profound Changes of Heavenly Flame, which would enable him to consecutively defeat opponents three levels higher in strength. However, as Xiao Yan used the strange fire, the poison spot on his body erupted.

Feng Xian promptly intervened to stop him and presented Xiao Yan with the Fire Lotus Bottle left behind by Yao Chen. It could contain the strange fire on his body and would be useful in the future fight against the Soul Hall's array. Xiao Yan became extremely excited upon hearing this and immediately began to experiment. However, even with the extraction of the strange fire, Xiao Yan's body still suffered damage. Xun'er approached and persuaded him not to use the strange fire so frequently.

Xiao Yan was surprised to learn that Xun'er knew about his inability to use the strange fire. Xun'er complained that he had kept such a big matter from her. She asked Xiao Yan to promise that he would never hide anything from her in the future, and that they would face life and death, happiness and sorrow together.

Xiao Yan solemnly promised Xun'er that he would never rashly make her worry in the future. The group arrived at the branch of the Soul Hall, and Ziyi cleared the way for everyone to enter. Mugu had prepared a powerful array to await them, and a fierce life-and-death battle ensued between the two sides. Everyone protected Xiao Yan as he went to save Yao Chen. Xiao Yan used the Fire Lotus Bottle to break the soul chain, but unexpectedly, Yao Chen had already been manipulated by Mugu and turned against Xiao Yan, launching a fatal attack.

Xiao Yan repeatedly evaded, but Mugu used the same trick again, manipulating Xiao Yan into becoming his tool and forcing him to kill Yao Chen. However, at the critical moment, Xiao Yan overcame himself with his willpower and regained his clarity. In order to kill Mugu, Xiao Yan disregarded everything and activated the strange fire, disabling Mugu's Dou Qi, but he himself fell unconscious on the ground.

After suffering severe injuries, Mugu fled in panic and arrived in a secret room. He hoped that Hun Mie Sheng would bestow power upon him, but unexpectedly, Hun Mie Sheng killed him because, in his eyes, Mugu's mission had already been fulfilled. Both Xiao Yan and Yao Chen fell into a coma, and Feng Xian said that only someone with an eight-clan bloodline could continue the meridians for Xiao Yan. Without regard for her own safety, Xun'er passed her bloodline to Xiao Yan, and indeed, Xiao Yan slowly regained consciousness.
