Ji Yun He is a spirit master with great spirit-taming skills. Her compassion for these spirits leads her to offend Envoy Zhang, who is a favored servant of Fairy Shun De. In order to seek revenge, he brings a merman to Wanhua Valley, and Fairy Shun De makes unreasonable demands for taming him. Lin Hao Qing accepts this task, but Ji Yun He volunteers to participate as well.

Yun He volunteers to participate in taming the merman. Knowing how risky it is, her best friend, Luo Luo, lectures Yun He for being impulsive. On the other hand, Lin Hao Qing is determined to win the battle against Yun He to restore his honor.

Yun He successfully wins Chang Yi's trust after she saves him from Lin Hao Qing's torture. When he puts himself in danger to save her, Yun He starts to feel guilty for using him. However, it all goes back to square one when Hao Qing sabotages her victory plan, and to add to her troubles, Xue San Yue also gets in her way.

Yun He and Jin Sang catch Xue San Yue and Li Shu sharing an intimate moment. Using this secret to her advantage, Yun He suggests forming an alliance with San Yue to escape from the valley. However, the key lies in winning Chang Yi's affection and convincing him to break his tail.

Ji Yun He and Chang Yi seem to have become closer. Si Yu and Lin Hao Qing suspect that there is something going on between Ji Yun He and Chang Yi, so they want to use an ancient treasure called the Lovers Test on everyone in the valley. Will Ji Yun He and Xue San Yue pass this test? How will they manage to surpass this?

Chang Yi makes up his mind to stay on the shore with Yun He. However, Yun He thinks that she doesn't deserve his trust. After learning the reason Chang Yi hurts Fairy Shun De, Yun He decides not to remove his tail. Instead, she wants to protect his kindness, which she sees as the most precious thing in this world.

Yun He and Chang Yi get stuck in the 10 Directions Formation as they try to escape the valley. Seeing the tragic end of Li Shu and Xue San Yue, Yun He tries to keep a distance from Chang Yi as she knows he will be hurt when he finds out about her lies, but it proves to be difficult. Yun He and Chang Yi meet the spirit of the Blue Feather Bird in the formation and quickly realize she may be the key to escaping.

In the 10 Directions Formation, the possessed spirit of the Blue Feather Bird continues to wait for her lover. Yun He and Chang Yi struggle to tell her the cold hard truth. Working together, Yun He and Chang Yi finally make it out of the formation, only to find themselves back in Wanhua Valley.

Yun He is in terrible shape, but she asks Qu Xiao Xing to tell Chang Yi not to believe anyone and that she is fine. Intent on winning, Lin Hao Qing brings Chang Yi to see the condition Yun He is in. Will Chang Yi decide to cut off his own tail, which is considered a betrayal to his clan?

Hao Qing offers to join hands with Yun He to take down his father. With that, Hao Qing promises to give her the antidote and guarantee her safety. However, Yun He has one more condition, which is to leave Wanhua Valley with Chang Yi after she helps Hao Qing become the master.

Yun He and Hao Qing decide to put their plan into action. Knowing Yun He and Hao Qing’s plan to dethrone him, Lin Cang Lan goes to the extreme to teach his son a valuable lesson to prepare him for the future. The miserable Blue Feather Bird gets a visitor that she least expects.

Lin Cang Lan's sudden passing leaves Wanhua Valley in shock. Yun He decides to support Hao Qing in succeeding Lin Cang Lan as the new master so she can leave with Chang Yi and Luo Luo. However, Hao Qing reveals the secret that his father had hidden all these years. Yun He's body has now deteriorated too badly and she will be in danger if she leaves.

Yun He devises a plan with Hao Qing to let Chang Yi escape, at the expense of her own life. On their way to Mount Lutai, Yun He and Chang Yi enjoy their last moments together in the Human Realm.

Hao Qing has never intended to help Yun He with Chang Yi's escape since the beginning. Instead, he frees Chang Yi knowing that the latter will go back to find Yun He. Seeing Chang Yi come to her rescue, Yun He has no choice but to hurt him in a cruel way.

Kong Ming, a former spirit master of Immortal Master's Mansion, saves Chang Yi from being captured in hope that he will agree to take down Immortal Master with him, but the heartbroken Chang Yi refuses. Immortal Master secretly keeps Yun He locked up as he knows she will be a useful pawn. The Heavenly King grows increasingly concerned about Fairy Shun De's willfulness and begins to doubt Immortal Master's morals.

\Chang Yi makes his way home to the East Sea, only to find himself ambushed. Devastated by the death of his father, Chang Yi decides to join forces with Kong Ming to fight against Immortal Master's Mansion. Meanwhile, Shun De delights in tormenting Yun He with the tragic news of the Merman King.

Shun De is adamant on making Yun He suffer by bringing her past enemies into Yun He's cell. Meanwhile, Chang Yi travels to the Northern Abyss in search of the Fox King to form an alliance to bring down Shun De and the Immortal Master.

Xue San Yue heads back to Wanhua Valley as she's certain Li Shu only cares about Ms. Qing. She then discovers a secret chamber in Hao Qing's inner hall, and she finds the antidote to Frost Mark in there. While San Yue is chased by Hao Qing for stealing the antidote, Li Shu appears in time to protect her.

Chang Yi almost dies from saving the immortals of the Northern Abyss, but Qing Yao and the Fox King manage to save him. A big alliance starts to form in the Northern Abyss to take down Immortal Master's Mansion, with Chang Yi as the chief commander. Fairy Shun De is determined to get back at them for attacking her by starting a war, but the Heavenly King does not support the idea.

The young Heavenly King is troubled by his sister's increasingly wicked desires. He decides to reach out to Yun He because she seems to have angered Shun De without suffering any grave consequences. The two meet, and Yun He confides in the young king about the Frost Mark. Together, they decide to devise a strategy to fight against Immortal Master.

Luo Luo finds the jar of wine Kong Ming left to chill in the Nine Frost Cave that is supposed to be offered to Master Qing in exchange for her help to take down Immortal Master. Meanwhile, Chang Yi proposes the plan to the Fox King to ambush the Immortal Master's Mansion.

Yun He instructs Luo Luo to save the imprisoned sinners, and she'll stay until all of them escape. When Ru Ling learns Yun He freed all the prisoners, she goes to Congji Prison immediately, wanting to take Yun He's life. However, just as she's close to killing Yun He, the magnificent Chang Yi appears to save Yun He.
