Episode 13 recap: "Hong Yi took action against A Yin, using the red silk as a cover.

Feng Ming explicitly told Gu Jin that he wanted half of the spiritual power of A Yin's Water Condensing Beast's inner core. Upon hearing Feng Ming's offer, A Yin was about to agree, as Feng Ming promised them both a share of the Immortal Fate of Feng Yin. However, Gu Jin stopped her because the inner core's spiritual power was A Yin's life essence, and giving it away would be akin to suicide.

After Gu Jin and A Yin rushed over, they witnessed Xian Zhu undergoing punishment from forty-nine lightning tribulations, with other senior brothers from Da Ze Mountain also present. At A Yin's suggestion, although everyone helped Xian Zhu endure a few lightning punishments, once the tribulations ended, Xian Zhu's immortal energy had already left his body. Seeing Xian Zhu barely clinging to life, everyone was at a loss. Hong Yi remembered the Soul-Scorching Grass of the Fox Clan, which could restore the immortal energy to its source. He volunteered to return to his clan to retrieve it and save Xian Zhu, and Xian Shan and the others thanked him.

Hong Yi arrived at the Fox Clan. Ever since Yan Shuang spoke up for her aunt, he felt his attitude towards his aunt was inappropriate. This time, he wanted to repair their relationship. When he saw his aunt, he took the initiative to admit his mistake. However, to his surprise, his aunt acted out of character. Not only did she refuse to give him the Soul-Scorching Grass, but she also made it clear that she was now the queen of the Fox Clan and that she had the final say in everything. She wouldn't spoil Hong Yi anymore, and if he didn't want to stay in the Fox Clan, he could leave.

Seeing Hong Yi walk away, Hong Ruo, who was under Qing Lin's control, struggled to stop him but was suppressed by Qing Lin. Hong Yi returned empty-handed, while Feng Ming brought the Burning Soul Lamp of their clan and arrived at Da Ze Mountain in the snow. Although the lamp was somewhat unreliable, Xian Shan and the others had no choice but to try anything at that point. Together, they infused spiritual power into the lamp, hoping to retrieve Xian Zhu's immortal energy through this method.

While everyone was infusing the lamp with spiritual power, Feng Ming discreetly threw the Godslayer Flower seed given to him by Zhao Ying near the celestial vein. With the influence of the Burning Soul Lamp, Gu Jin and A Yin's souls separated from their bodies. Just as they found Xian Zhu's immortal energy, the King of the Netherworld suddenly appeared before them. Although Xian Zhu's lifespan was not yet over, driven by grief over his lover's death, he had ventured into the Netherworld. Gu Jin watched as Xian Zhu was taken away by the King of the Netherworld. Once their souls returned to their bodies, Gu Jin decided to go to the Netherworld with A Yin to rescue Xian Zhu.

After arriving in the Netherworld, Gu Jin and A Yin first met with Xiu Yan because the Three Lives Stone had returned. As promised, Xiu Yan gave them the special token. Holding the token, they easily encountered the King of the Netherworld, Ao Ge. Ao Ge told Gu Jin that if A Yin, the Water Condensing Beast, could provide half of the inner core's spiritual power, he would release Xian Zhu.

A Yin was about to agree when Feng Ming offered them both a share of the Immortal Fate of Feng Yin. However, Gu Jin stopped her because for A Yin, the spiritual power of the inner core was her life, and giving it away would be tantamount to suicide."

A Yin was trying to persuade Gu Jin when the Three Lives Stone suddenly barged in and advised them not to agree to Ao Ge's request. According to the agreement between Xiu Yan and Ao Ge, anyone who possessed the special token could not only instantly see Ao Ge but also make one request that he would fulfill. Upon hearing the Three Lives Stone's words, Ao Ge appeared visibly uneasy but presented Gu Jin and A Yin with two choices. He knew that they had come to the Netherworld to find Feng Yin's Immortal Fate and asked them to reconsider. If A Yin could leave behind half of her spiritual power, both requests could be fulfilled. However, Gu Jin ultimately chose to take Xian Zhu away.

After Gu Jin and A Yin left, Ao Ge scolded the Three Lives Stone and then went to Xiu Yan's tower to chat with him. Xiu Yan told Ao Ge not to overthink it, as even if A Yin left behind half of her spiritual power, it was uncertain whether his inner core could be repaired. He also advised Ao Ge not to always wear a stern face since now, in the realm of the Netherworld, only the Three Lives Stone dared to joke with him.

In fact, it was Xiu Yan who had instructed the Three Lives Stone to help Gu Jin and A Yin. Everyone was overjoyed to see Xian Zhu awaken, but after waking up, he learned that the woman he loved had already passed away and coughed up some blood in distress. The mortal woman Xian Zhu loved was named Wan Yue, and A Yin showed him a letter left by Wan Yue. After Xian Zhu's emotions settled down, A Yin began to heal his injuries. Seeing A Yin looking exhausted, Gu Jin embraced her shoulder with concern when Hong Chou suddenly walked in.

Hong Chou took out a pill and had Xian Zhu consume it, relieving A Yin of the need to deplete her spiritual power. Then he called Gu Jin outside and reminded him not to develop feelings for A Yin. When the Eastern Divine Lord established the master-servant contract between them, it was to prevent them from falling in love. However, Gu Jin told Hong Chou that he and A Yin had mutual affection and that she didn't need to interfere. Seeing Gu Jin's stubbornness, Hong Chou decided to find a way to separate the two.

Gu Jin and A Yin were about to enter a marriage contract when A Yin was deceived by Hong Chou to pick Forget-Worry Fruit to save Xian Zhu. While A Yin was picking the fruit, Hong Chou pushed her off a cliff. Luckily, Xian Shan appeared just in time, and A Yin was saved from harm. Xian Shan discovered that Hong Chou's intention in harming A Yin was to prevent Gu Jin from falling in love with her because A Yin was Gu Jin's destined tribulation.

To help Gu Jin avoid his tribulation, Xian Shan came up with a win-win solution. There was a treasure in Da Ze Mountain called the Forget-Memory Flute. Xian Shan informed Hong Chou that this treasure could extract Gu Jin's feelings.
