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.

Chang Yi confines Yun He on Huxin Island, but his actions confuse everyone as he does not torture her like he vowed to. Qing Yao's maid sees Yun He use Qing Shu's red Fox Fire, which makes Qing Yao and Qi Feng suspect that Yun He harmed their aunt. Lin Hao Qing tries to steal the antidote from Immortal Master and ends up discovering his secret chamber.

Yun He is now locked up on Huxin Island. Seeking an explanation, Chang Yi torments Yun He by making her lose her freedom. However, out of love, Yun He cannot bear to tell him the truth. To make things worse, their misunderstanding deepens when Yun He tries to escape.

Qing Yao proposes that Chang Yi becomes the Master of the Northern Abyss which Chang Yi agrees to after some hesitation. However, he runs off in the middle of the coronation ceremony after sensing trouble with Yun He, bringing shame to the Northern Abyss and the Fox Clan.

Chang Yi invites Kong Ming to assess Yun He's condition, only to find out she has about a month to live. Ru Ling finds a painting in Immortal Master's secret chamber, and the lady in the painting resembles her. She's devastated to learn she has been someone else's substitute all along.

The Frost Mark starts to take effect on the spirit masters in Wanhua Valley. To advance his plan against Immortal Master, Lin Hao Qing offers to join hands with Fairy Shun De and lead Wanhua Valley to attack the Northern Abyss. While she agrees, she also threatens to kill Yun He. San Yue sets off to Mount Daiyu to find the Nectar Lingzhi mushroom to prolong Yun He's life.

With Wanhua Valley's army attacking them, Chang Yi's ambush and formation are carried out successfully. However, Qi Feng's defiance gives Lin Hao Qing a chance to break the formation. To strike a deal for a negotiation, Lin Hao Qing asks Chang Yi to hand over Yun He.

In a mission to capture Spirit Masters, Master Qing captures Hao Qing instead. Littlle do they know that he let himself get caught on purpose to meet Yun He. In the Frost Pavilion, Yun He and Hao Qing comes up with their one last plan to escape.

Heavenly King uses Immortal Token left by his father to block the lightning strike as a last resort to save San Yue and Li Shu. The token shatters to pieces and reveals a secret map. On the other hand, Yun He and Hao Qing attempt to run away, but they run into Fox King and his clan during the escape.

Ji Yun He appears as war is about to break out and convinces Wanhua Valley to defect to the Northern Abyss. Zhu Ling triggers the Frost Mark on all the spirit masters' bodies in retaliation, so Yun He sacrifices herself to save them all. With Yun He gone, Chang Yi deeply regrets not being honest with his feelings before she died. After hearing about Yun He's death, the Heavenly King finally takes action against Fairy Shun De.

Fairy Shun De is locked up in Immortal Master's Mansion, and Yun He is dead. The world seems to come to a temporary peace, so the young Heavenly King sets out in search of a mysterious mountain that is said to have increased Ning Qing's powers. Just then, Lin Hao Qing brings home a little Nine-Tailed Fox back to Wanhua Valley.

Zhu Ling helps Fairy Shun De to capture the escaped Spirit Masters despite Cheng Yu's objection. Desperate Cheng Yu writes a letter to Kong Ming to tell him of the situation. Chang Yi keeps himself busy to stop himself from thinking about Yun He. Meanwhile, Hao Qing raises a Nine-Tailed Fox named Ji.

Elder Dong Lian and his team are ambushed and captured by Zhu Ling while looking for Thistle herbs. WIth no choice, Hao Qing tells Ji to head to the south alone to find his old acquaintances who will look after her for him. After leaving Wanhua Valley, Ji travels to the Human Realm and encounters Luo Luo there.

Ji goes to the Northern Abyss to break Lu Jin Yan out of prison, but they get captured by Chang Yi. Chang Yi finds her suspicious as her words and actions remind him of Yun He. Lin Hao Qing pretends to pledge allegiance to Fairy Shun De again for the sake of saving Wanhua Valley. Meanwhile, Immortal Master continues actioning his plan discreetly in the background.

The Heavenly King finds information on the mysterious Mount Wuliang. With Li Shu's help, they manage to enter the mountain, and the Master of Four Direction's primordial spirit appears to reveal the truth behind the battle from 1,000 years ago. To end the chaos, Zhu Yan's last piece of soul must be sealed in the Azure Heart Lamp. But will the damaged lamp be fixed in time?

After finding out Ji's whereabouts, Hao Qing goes to take her home. But Ji is reluctant to leave and is curious about the merman that gives her strange feelings. When the Northern Abyss is under Fairy Shun De's attack, Ji goes to stop the calamity only to learn of her past.

After leaving the Northern Abyss, Lin Hao Qing decides to go to Mount Lutai to get rid of Zhuyan. Yun He finally wakes up, and she asks Chang Yi to take her somewhere high up to see the whole of the Northern Abyss. As they admire the scenery, they start to confess their true feelings to each other.

Knowing that Ning Xi Yu is the only one who can make Immortal Master come to his senses, Yun He brings him into her dream to see his master. Immortal Master indeed ends up sacrificing himself, and Zhuyan is defeated, but a new evil threat is born soon after. Yun He makes a bold request to Chang Yi when she finds out he has very little time left to live.

Chang Yi and Yun He announce to be married in three days. The Northern Abyss is still preparing for Shun De's attack, so the wedding is kept simple. However, Luo Luo finds Kong Ming's gloominess baffling. Unknown to everyone, the Ice Seal within Chang Yi will erupt at midnight on his wedding day.

Chang Yi is frozen in the Ice Seal as Shun De prepares to go to war with the Northern Abyss. The Heavenly King restores the Azure Heart Lamp, but the Sky Fire is needed to light it up. There's only one person who is capable of doing it as it comes with a sacrifice.

Unwilling to give up, Shun De decides to turn into the wind so that she can continue to kill all the beings in the world. Yun He uses her body as a container to trap Shun De's evil aura, and she decides to perish with her by jumping into the lava. Meanwhile, Luo Luo protects Kong Ming from Cheng Yu when the latter tries to kill Kong Ming.
