Episode 20 recap: "A Yin's lifespan is running out.

Seeing A Yin unconscious on the bed, Gu Jin anxiously asked Xian Shan if there was any way to extend A Yin's life within fifty years. Before Xian Shan could respond, Xian Zhu immediately informed Gu Jin that A Yin had been injured by demonic energy while in the womb and originally had only ten years of life. Now, half of it had been given to the King of the Underworld. Yan Shuang calculated that A Yin had already lived for four years, which meant she had only one year left, according to Xian Zhu's statement.

After winning back the Ning Yun Mountain, Gu Jin had it delivered to A Yin through the Emperor Lan Feng and instructed him not to reveal his true identity. Although Emperor Lan Feng found it strange why Gu Jin didn't personally deliver it to A Yin, he followed Gu Jin's instructions and gave the mountain master's order to A Yin. However, A Yin was not as happy as expected because of Gu Jin's influence, and Gu Jin felt uneasy seeing A Yin's low spirits.

In the heavenly palace, there were five vacant positions for election. Hua Shu was surprised to find that Emperor Lan Feng was absent and went to visit him specifically. Upon seeing Emperor Lan Feng undergoing punishment, she immediately realized that he already knew she had framed A Yin for borrowing the spirit arrow. Although Emperor Lan Feng didn't blame her, he believed that Hua Shu had done it solely for the benefit of the Peacock Clan.

Emperor Lan Feng told Hua Shu that if he loved her, he had to love all of her. He knew that Hua Shu had made many sacrifices for the Peacock Clan's interests, but as the Heavenly Emperor, he had to act justly. When the time came for him to leave his position, he would definitely share her burdens. Touched by Emperor Lan Feng's sincerity, Hua Shu couldn't help but embrace him.

Qing Lin handed over the Divine Slayer Flower seeds to the Peacock King and asked him to plant them in the fairy veins of the Da Ze Mountain. To coordinate with the Peacock King's actions, Qing Lin sent Zuo Ying to find Feng Ming and distract Xian Shan, Xian Zhu, and others. During this incident involving the spirit arrow, Feng Ming was nearly exposed. She initially didn't want to do anything for Zuo Ying again, but considering the position of the Phoenix Emperor, she eventually agreed to Zuo Ying's request.

Xian Shan, Xian Zhu, and others were preparing to reinforce the fairy veins of Da Ze Mountain when Feng Ming suddenly sent a message saying that the Linglong Pagoda on Phoenix Mountain had started to loosen. After receiving the news, Xian Shan and the others rushed over. By the time they arrived at Phoenix Mountain, Gu Jin had already sensed it. Feng Ming informed everyone that there was no longer any immortal element from Feng Yin and they could only stabilize the Linglong Pagoda by sacrificing one person's immortal element. Gu Jin felt responsible for this disaster and decided to contribute his own immortal element.

Qing Shan was worried that once Gu Jin's immortal element was given away, it couldn't be recovered, so he informed A Yin and the others about the situation. A Yin then sent Hong Yi and Yan Shuang to stop Gu Jin, while she went alone to the You Ming Realm and made a trade with Ao Ge, using half of her spiritual power in exchange.

After she gave her spiritual power to Xiu Yuan, Xiu Yuan gave him Feng Yin's two portions of the immortal element. To express gratitude to A Yin, Xiu Yuan also used his own power to elevate A Yin's cultivation to the lower immortal level."

A Yin suspected that Xiu Yuan was Ao Ge through the ring on his hand. To clarify any misunderstandings, Xiu Yuan revealed his relationship with Ao Ge. Xiu Yuan and Ao Ge were originally twins, with Ao Ge in charge of the Immortal Palace and Xiu Yuan managing the You Ming Realm. Approximately 110,000 years ago, when the barrier of the underworld weakened, the Demon Lord escaped from within. During the rebellion, Xiu Yuan sacrificed himself to seal the Demon Lord once again. Unable to accept his brother's demise, Ao Ge sought the help of Yi He Zhen Shen to save Xiu Yuan. Yi He Zhen Shen taught him a method to use his own body to regenerate Xiu Yuan's inner core and made a request for Ao Ge to replace Xiu Yuan and govern the You Ming Realm in his stead.

While the two were conversing, Xiu Yuan and the Demon Lord were also chatting. The Demon Lord used fragments of Xiu Yuan's inner core to reshape his body. The Demon Lord wanted Xiu Yuan to release him, but Xiu Yuan refused. Hong Yi and Yan Shuang arrived at the Phoenix Mountain and saw Gu Jin exhausted and coughing up blood. They hurriedly stopped him and informed him about A Yin's journey to the You Ming Realm.

Gu Jin rushed to the You Ming Realm, and A Yin gave him Feng Yin's two portions of immortal essence, assuring him not to feel burdened. She did it solely to repay his kindness. After saying this, A Yin collapsed to the ground. Gu Jin carried A Yin back and anxiously asked Xian Shan if there was any way to extend her life within fifty years. Before Xian Shan could respond, Xian Zhu informed Gu Jin that A Yin had been injured by demonic energy while in the womb and originally had only ten years of life. Now, half of it had been given to the King of the Underworld. Yan Shuang calculated that A Yin had already lived for four years. According to Xian Zhu's statement, she had only one year left.
