It is said that the only descendant of the ancient bloodline, the Four-Leaf Lotus, is in full bloom. And Four-Leaf Lotus can heal all things. While the immortals are looking forward to it, the elder from the Demon Realm disregards the advice and wants to pluck it. Sovereign Lord Ying Yuan who is in charge of the celestial troops comes forward to stop him in order to maintain the peace of the Six Realms.

Yan Dan doesn't know that Yu Mo is the descendant of the Nine Fins Clan. Nine Fins Clan was once known as the strongest clan in the Six Realms. And Yu Mo is the only remaining bloodline in Nine Fins Clan. He was secretly resettled after being rescued by an immortal many years ago.

Yan Dan is worried that no one can protect the celestial tortoise if she's transferred away from Xuanxin Cliff. Yu Mo suggests helping the celestial tortoise to acquire a celestial form as soon as possible.

Zhi Xi hears about the legend of a weaker being among the Twin Lotuses and asked who is stronger among them. Yan Dan says it is Zhi Xi but Yu Mo says no one is better than Yan Dan when it comes to intelligence and spiritual power.

Ying Yuan brings Yan Dan to the Corner of Heaven. Yan Dan excitedly catches the flowing immortal power starlight. She collects the remnants of the fallen stardust and fills a bottle full of it, intending to give it to her sister later.

Yan Dan finds out that Yu Mo was dead drunk, Yu Mo talked about the tragic fate of his parents when he was drunk. Only then, Yan Dan understands that Yu Mo is from the Nine Fins Clan. However, no matter what Yu Mo had experienced, the current him will always be her follower. Yan Dan's decision to remain quiet about it consoles Yu Mo's grief and insecurity.

Ying Yuan woke up from unconsciousness, and realized he's completely blind. He also got to know the news that Huan Qin sacrificed himself during the battle with Xuan Xiang.

Yu Mo is heartbroken. Back when he was on the brink of death, an old immortal saved him from the battlefield. The old Immortal crushed his magical item to heal his wounds, which preserved Yu Mo's true form.

Yu Mo goes to the stage to explain at night but no one is there. Yu Mo thinks Yan Dan is angry because he did not risk his identity to find her. In the end, Yu Mo finds her performing “Tale of the Genesis Hero” for Ying Yuan.

The frail Yan Dan uses her life energy to suppress the toxin for Ying Yuan. Then, she brings him into a hut to treat him. Both of them spend their time together in the hut. Yan Dan trades her life energy to materialize the Lotus Flower so that she can burn the petals in an incense burner to slow down the spread of the toxin in Ying Yuan.

Yan Dan enters Ying Yuan's dream, realizing that he has fallen for her all along. Yan Dan rips out her heart to make the Lotus Heart Remedy for Ying Yuan so that he can regain his sight. Yan Dan receives nine strikes of thunder after impersonating Zhi Xi, who has misused her power for the sake of obtaining the Fuxuan Cauldron.

Zhi Xi impersonates Yan Dan and pretends that she has saved Ying Yuan. Ying Yuan suspects her words, but keeps quiet to avoid hurting Yan Dan's feelings. Zhi Xi lies to Yan Dan about her situation. Ying Deng convinces Zhi Xi to frame Yan Dan in an attempt to get rid of her.

Yu Mo's identity as a descendant of the Nine Fins Clan is almost exposed when Ao Xuan uses the Blazing Dragon Flame on him. Luckily, Yan Dan goes to his rescue by using the Snow Lingzhi as an excuse. Ying Deng pretends to be poisoned and frames Yan Dan for it. Yan Dan is sent to the Heavenly Prison and awaits her punishment.

Zhi Xi questions Ying Deng about her decision to frame Yan Dan. Ying Deng replies that it's too late for her to regret it. Ying Yuan finds out that Ying Deng poisoned herself. However, he cannot reveal the truth as Ying Deng threatens him that she will report his relationship with Yan Dan to the Supreme God.

Yan Dan chooses to jump down from Liao Wu Bridge instead of accepting the Love Execution. Ying Yuan jumps down to save her. However, she has to cross the Night Forgetting River to forget about her past and be reincarnated as a human. Ying Yuan goes back to the Nine Heavens and asks for a Love Execution.

Zhi Xi becomes a celestial official. Ying Yuan orders her to deal with Yan Dan's belongings. Zhi Xi enters Yan Dan's room, finding two bottles of stardust. One has a note attached to it.

Yan Dan has only three days left until 900 years. Ying Yuan is worried that if she still can't cross it, she'll die. He can't leave her be. So, he knocks out Yan Dan with his celestial power. Ying Yuan is willing to sacrifice his celestial power and decides to use his own celestial spirit as a vessel to erase Yan Dan's memories.

A mysterious and powerful figure injures Ying Yuan and damages his celestial spirit. Ying Yuan uses his all to defend himself. The black figure disappeared after getting injured. Ying Yuan returns to the God of Death's cell, only to find out that both him and his guard were killed. He has doubts about the Celestial-Demon War that happened 800 years ago. He decides to head back and investigate the case.

Back in the Nine Heavens, Ying Yuan is recuperating in his palace. He then visits His Supreme Majesty and tells him about his ambush in Hades' Realm. He is ordered to investigate the matter. Ying Yuan tells the Supreme God about his suspicion of the Celestial-Demon War. After the war, the territories of the Demon Realm are under the Mortal Realm now. So, he decides to enter the Mortal Realm with the excuse of going through a trial to look for the truth.

Yan Dan finds the Flower Spirit Clan successfully and becomes one of them. They are choosing a beauty for the mountain chief of Yelan Mountain as a concubine. They are offering the Pill of Yanbi, the secret treasure of the clan too. To steal the Pill of Yanbi, Yan Dan volunteers to be one of the beauties by showing them her playwriting talents.

Yu Mo rushes to the Flower Spirit Clan's hideout, not knowing that the team who was escorting the beauties had just departed. Yu Mo returns to the Mountain Realm dejectedly. Zi Lin realizes that Yu Mo was very weak. He predicts that Yu Mo has given his Unique Eye to Jiang Chen.

Lin Lang, princess of the Wolf Clan, begs Yu Mo to dispel the curse on Zi Yan, her younger brother. She's willing to devote her heart to her benefactor, according to the rules of the Wolf Clan.

Yu Mo decides to travel around with Yan Dan and fulfill his duties as the mountain chief to punish the evil spirits that are plaguing the Mortal Realm.

There's a trap at the entrance of the Consort's Tomb. When they are at a loss for what to do, Yan Dan manages to piece together a clue from Shen Xiang Jun's nonsensical words. In the end, they manage to find the right entrance into the tomb.

Shen Xiang Jun's servant invites Yan Dan and Tang Zhou to exorcise the Shen Residence. Tang Zhou realizes that Master Shen and Shen Xiang Jun were acting strangely. They discover the shocking truth after their investigation.

First Senior Dao Yuan has feelings for Yan Dan. But every time he tries to approach her, he is stopped by Tang Zhou. Thus, he harbors a grudge toward Tang Zhou. He's also jealous of the Sect Leader's biased affection towards Tang Zhou. He tries to look for Tang Zhou's weakness to defeat him.

Yu Mo, Yan Dan, and Tang Zhou finally meet each other in the capital of Andu. Yan Dan wishes to introduce Yu Mo to Tang Zhou. However, Yu Mo refuses her good will. They fight immediately. Yan Dan persuades them to stop. They finally stop fighting after her noble effort.

Tang Zhou, Yu Mo, and Yan Dan discover a huge amount of spiritual power gathering in Lord of Andu's palace. Yu Mo converses with Pei Luo in an attempt to get information of his secret practice. Tang Zhou enters his chambers and discovers a shocking secret in the secret chamber behind the wall.

Tang Zhou discovers artifacts filled with blood inside Lord of Andu's secret chamber. A large cauldron was spewing fire. It was actually Pei Luo's secret elixir chamber. He was the one who tried to create elixirs from young children's blood in an attempt to attain immortality.

Yan Dan and the other three leave the capital of Andu. Ying Deng's plot worked. She pretends to be weak and clings to Tang Zhou. She tried to be on good terms with Yan Dan to inquire about Tang Zhou. Yu Mo is suspicious of Ying Deng's identity.

In order to save Zhao Lan, Tang Zhou and his companions sneaked into the East Sea. They find out that the Aqua Clan is being oppressed by the Dragon Clan of the East Sea. Together, all three of them help a lot of the weaker Aqua Clans. While doing that, the elder of the Aqua Clan recognizes his power as the Nine Fins. The Nine Fins Clan used to be the ruler of the Four Seas. So, the other Aqua Clans start to seek refuge with Yu Mo as well.

Yan Dan and the other two reveal their plan to assassinate Ao Xuan during the wedding banquet in front of Ying Deng deliberately. Ying Deng tells Ao Xuan about their plan. He stations his troops in the hall in order to capture Yu Mo and the rest.

After the East Sea is in peace again, the Aqua Clan elects Yu Mo to become the Dragon King of the Four Seas. But they are turned down by Yu Mo. Zhao Lan musters her courage to confess to Yu Mo and is rejected by Yu Mo too.

Yan Dan realizes that Liu Wei Yang is trying to make her talk and starts to get suspicious of him. After Yu Mo's investigation, they realize that the Yang family was non-existant. And, Liu Wei Yang wasn't as frivolous as he seemed. They suspect him of faking his identity for another purpose.

Yan Dan deduces that the Illusion of Demons contains clues regarding the third divine artifact. The trio decides to work together with Liu Wei Yang and assist him in retrieving his memories in the Illusion of Demons. Liu Wei Yang assists them in searching for the divine artifact.

The four of them travel to the Demon King's palace. They found the third divine artifact, which could resurrect the dead. Just when Tang Zhou was about to take it, a mysterious figure suddenly appeared and attacked them.

The three of them, including Yan Dan, reach Bone Mountain in the Life and Death Arena. They find Liu Wei Yang there. He admits that he was once the Demon King, Xuan Xiang. He regains his memories as Xuan Xiang after seeing an exact copy of his face under the veil in the Illusions of Demons.

Yan Dan recovers her memories, remembering that she was a lotus fairy in the Heavenly Court and that her fate was entertwined with Sovereign Lord Ying Yuan. Yan Dan stares at Tang Zhou, who was embracing her tightly. She finally understands that Tang Zhou is Ying Yuan of the Nine Heavens. He's the man who broke her heart before. The pain in her heart is unexpressable.

Tang Zhou gathers his courage and confesses to Yan Dan. He crushes the Pearl of Memory given by the Dragon King to prove his conviction in forgetting the past and his willingness to cherish the present. Although Yan Dan knows that Tang Zhou has no memories of his times as Ying Yuan, she still cannot get over it. She rejects him coldly, destroying the Chenhua Hairpin, which binds them together, and requests Tang Zhou to remove the Distance-Keeping Bracelet. If not, she'll break her arm in an attempt to leave Tang Zhou.

Yu Mo writes a letter to Yelan Mountain, summoning Yan Dan's friends from the mountain realm to come and help. Zi Lin, Lin Lang, Bai Ling, Dan Shu and Zi Yan arrive in a rush and decide to work together to help Yu Mo keep Yan Dan.

Yan Dan and Yu Mo goes to the temple festival with all the little demons to help match Zi Lin and Lin Lang together. Yan Dan notices the wish on Tang Zhou's flower lantern hoping for "Peace to the world". She remembers Ying Yuan's wish for the peace of six realms and knows that Tang Zhou is actually still Ying Yuan deep inside.

Many little demons of Yelan Mountain are missing and the clues point to Lingxiao Sect. After Yu Mo's investigation, he finds Cang Hong, the Sect Leader to not be as honest as he seems because he makes pills from killing demons. Tang Zhou doesn't believe him and sneaks inside Lingxiao Sect with Yan Dan and Yu Mo to investigate. He gets angry after seeing the Sect Leader making pills and killing demons.

After the sect leader's death, Lingxiao Sect was left without a leader. Each disciple established their own rules, causing the sect to fall into ruins. It was hard for them to make a living. They were teased as they failed to subdue a cat spirit. Tang Zhou felt guilty. He intends to assist them. However, he was seen as a traitor, and was hated by his juniors and seniors. Yan Dan and Yu Mo assist Tang Zhou in his training. They subdued the cat spirit with their wits and saved the reputation of Lingxiao Sect. Tang Zhou reconciled with his fellow disicples, and his trouble was resolved.

Bai Ling hurriedly comes forward to report to Yu Mo. The Mountain Realm is in trouble. Zi Lin and Lin Lang have gone missing and their lives are at stake. At the same time, Tang Zhou receives a secret message from a mysterious man through the Invisible Beast. According to his message, Tang Zhou is required to bring the three divine artifacts to Fengquan Valley to give them to him in exchange for the hostage. Otherwise, not long Zi Lin and Lin Lang will be killed, the whole Mountain Realm will be destroyed too.

Due to the Palm of Withering, Tang Zhou is unable to absorb any spirit power. His wound was unable to heal. They have no choice but to seek out the fourth divine artifact to protect him. Yan Dan feels guilty about it. No matter what she does, it doesn't work. She feels anxious as she cannot find a cure. Tang Zhou feels nonchalant about it. He consoles Yan Dan instead and tells her not to feel guilty. He says that even if he shall die after several decades, he won't have any regrets as long as he spends his time with Yan Dan.

In the Nine Heavens, The Heavenly Emperor receives a report that the lost divine artifact, Dizhi, was in Yelan Mountain. However, its exact location was unknown. The Heavenly Emperor orders Zhi Xi, the handler of divine artifacts, to search for it in the Mortal Realm. Zhi Xi heads to Yelan Mountain and bumps into Tang Zhou, who was lying unconsciously. Zhi Xi stabilizes Tang Zhou's celestial spirit with some celestial medicine. She also discovers that Yan Dan was in Yelan Mountain by accident.

Yan Dan dispels Zhi Xi's magic circle and rushes to find Tang Zhou. Coincidentally, she saw the scene where Tang Zhou saw through Zhi Xi's disguise. She was touched by him. She understood that Tang Zhou was no longer the Ying Yuan who mistook Zhi Xi for her.

The Heavenly Realm finds out that the Sovereign Lord has regained his power. They urge him to return to the Heavenly Realm. Yu Mo also advises Ying Yuan to get on with the investigation at once. Ying Yuan has no choice but to leave the unconscious Yan Dan to Yu Mo and Zhi Xi. Then, he hardens his heart and leaves her.

Ying Yuan finds Yan Dan and wants to crush his own celestial spirit to show his resolve to spend the rest of his life with Yan Dan. Yan Dan stops him and tells him how much she knows about the importance of the responsibility of a Sovereign Lord. Yan Dan says they each have their own responsibilities and urges Ying Yuan to solve the conspiracy and protect the Three Realms. She tells Ying Yuan their fate has ended and won't start all over again before turning around and leaving ruthlessly.

Both of them return to the Heavenly Realm to visit Lu Ming in an attempt to investigate the case. Yan Dan discovers that Lu Ming has left behind many books related to belts. She was confused. When night comes, both of them were planning to leave as they found nothing. Yan Dan realizes that several candles in the pavilion cannot be put out. She realizes that Lu Ming used his blood to create the Eternal Candles and hid them inside the Pavilion of Books as clues. Ying Yuan discovers that the positions of the Eternal Candles had formed the Nine-star Alignment.

Yan Dan finds out that the Heavenly Emperor has gathered the deities and summoned Ying Yuan. She transforms into Zhi Xi and heads to Lingxiao Hall as she's worried about him. The Heavenly Emperor exposes her in front of everyone and points out that Ying Yuan has fallen for Yan Dan, breaking the love abstinence. He tests them with the Severing Cord. The Severing Cord stays intact and forms a know instead. Ying Yuan and Yan Dan look at each other, knowing that it's hard to hide their feelings for each other.

In order to protecting Ying Yuan and Yan Dan, Zhi Xi fought against Supreme Lord by different Divine Artifacts. Supreme Lord warned that if she helped them, she would be sent to the prison. Yan Dan begged her to stop but Zhi Xi was reluctant and didn't break the promise at that time so she would always protect Yan Dan.

Ying Yuan remembers the moment when he nearly went berserk when he was repairing the Celestial-Demon Barrier. The Heavenly Emperor gave him a sliver of his primordial spirit. Ying Yuan intends to use that to revive the Heavenly Emperor. However, the primordial spirit turns into the Heavenly Emperor's phantom and stops him. The phantom explains the secret of Ying Yuan's background.

Ying Yuan was shocked when he found out about his identity. The Heavenly Emperor points out that Ying Yuan has the blood of Asura, and only his primordial spirit can suppress that power. If Ying Yuan goes berserk, the Three Realms will face a calamity. Therefore, the Heavenly Emperor forbids Ying Yuan from extracting his primordial spirit. He would rather give up on his chance of being revived so that Ying Yuan could investigate the truth and rid the world of a great evil.

Ying Yuan infiltrates the Heavenly Realm to find Yan Dan. The fake emperor sees Ying Yuan as a rebel and orders Heavenly Soldiers to arrest him. Huo De, other deities and the heavenly soldiers were in Ying Yuan's care in the past so they disobey the emperor's orders and release Ying Yuan.

Ying Yuan exposes all of Huan Qin's crimes in front of the deities and reveals that he's from the Asura Clan. The deities are furious. They want to seek justice for the Heavenly Emperor and the Sovereign Lords for their unjust death. They want to take back their own celestial power too. Huan Qin fears nothing because he has the power of the Sovereign Lords and the Demon Clan. He discards his facade at the banquet and absorbs all the deities' celestial power.

Ying Yuan brings out the divine artifact, Dizhi, and fights Huan Qin alongside Yan Dan, Yu Mo, and other deities. Huan Qin was powerful enough to destroy Dizhi. Ignoring the pain, Ying Yuan retaliates with Eternal Darkness. Yan Dan comes up with a plan to retrieve the Three Divine Artifacts in Huan Qin's hand.

Everything has changed in the Heavenly Realm. In the absence of a leader, Ying Yuan takes the position of Heavenly Emperor under the deities' request. He eliminates the rest of the rebels, holds a memorial for the dead heroes, and takes charge of the governing of the Heavenly Realm. To prevent Huan Qin from attacking them again, Ying Yuan decides to restore his celestial spirit. He's going to tame the three divine artifacts to fight Huan Qin once and for all.

Ying Yuan almost goes berserk with the overflowing divine power. In the end, he conquers his inner demon and helps his father to turn over a new leaf. Xuan Ye vanishes. However, it was too late. The barrier between the Demon and Heavenly Realm has already vanished. Huan Qin uses the opportunity to summon the remaining demons to attack the Three Realms.
