With the complete eradication of the evil forces, the mission of Li Xiaoyao and others has also ended. However, while celebrating the joy of victory, they discover a shocking secret. It turns out that the rise of this evil force is not accidental, but stems from a more powerful mastermind behind the scenes. This black hand is secretly manipulating everything, trying to disturb the balance of the Three Realms, so as to achieve the goal of controlling heaven and earth.

Li Xiaoyao felt a heavy responsibility and decided to lead everyone to continue to investigate the matter. They first came to the mysterious tomb occupied by the forces of evil, hoping to find some clues from it. In the tomb, they found a long-sealed ancient book that recorded an ancient legend about an evil creature known as the "Heavenly Demon" who tried to dominate the Three Realms, but was sealed by a mysterious swordsman.

After some research, Li Xiaoyao and the others found that the evil forces that were originally defeated by them were controlled by the "Heavenly Demon". And now, the "Heavenly Demon" has gradually regained its strength and is ready to make a comeback. In order to stop all this, Li Xiaoyao and the others decided to find the mysterious swordsman, hoping that he could teach them the method of sealing the "Heavenly Demon".

After some twists and turns, they finally found the heir of the swordsman, a woman named Zixuan. Zixuan told them that in order to seal the "Heavenly Demon", they had to collect three artifacts: the Xuanyuan Sword, the Shennong Ding, and the Fuxi Qin. These three artifacts represent the power of the three worlds of heaven, earth and man, and only when their powers are combined can the "Heavenly Demons" be completely destroyed.

Under Zixuan's guidance, Li Xiaoyao and the others began their adventure to find the artifact. After a lot of hardship, they finally found these three artifacts in various dangers. Just as they were about to hand over the artifact to Zixuan, they found that Zixuan was originally possessed by the "Heavenly Demon". It turned out that Zixuan had already been controlled by the "Heavenly Demon", and her purpose was to lure Li Xiaoyao and others to find the artifact, so that the "Heavenly Demon" could gain endless power.

In the face of all this, Li Xiaoyao did not flinch. He knew that they had no choice but to face the "Heavenly Demons" bravely. In a fierce battle, Li Xiaoyao relied on the power of three artifacts to finally eliminate the "Heavenly Demon" and restore peace in the Three Realms.

This thrilling adventure has finally come to an end, and Li Xiaoyao and the others have returned to their respective worlds. However, this experience made them cherish each other's friendship even more, and it also made them understand that only by working together can they overcome all difficulties. For Li Xiaoyao, this experience made him understand his responsibility, and he vowed that no matter what difficulties he encountered in the future, he would bravely stand up and protect the people he loved and the world.

After that fierce battle, although Li Xiaoyao and the others successfully eliminated the "Heavenly Demon", they also knew that similar evil forces might still appear. As a precaution, they decided to establish an alliance in the human world, the fairy world, and the demon world to jointly protect the peace of the Three Realms.

In this process, the relationship between Li Xiaoyao and Zhao Linger became deeper. They have experienced life and death together, and they have long regarded each other as the most important people in their lives. Finally, on a sunny day, with the blessing of everyone, they tied the knot and started a new life.

Lin Yueru also found her own happiness in this adventure. She met a Miao girl named Anu, and the two complemented each other and became inseparable friends. In the end, Anu became Lin Yueru's partner, and they returned to the fairy world together and lived a happy life.

And after the "Heavenly Demon" was eliminated, Zixuan finally got out of control and regained her original temperament. She was grateful for the help of Li Xiaoyao and others, and decided to stay in the human world and help them protect the peace of the Three Realms. In the process, Zixuan and Li Xiaoyao established a deep friendship and became their indispensable partner.

In this way, Li Xiaoyao, Zhao Ling'er, Lin Yueru and Zixuan became the core force of the Three Realms Guardian Alliance. Together, they guard the peace of the Three Realms. And their stories have become heroic legends that have been passed down to future generations, inspiring generations to fight bravely for justice and peace.

However, the world is always full of unknowns and challenges. While Li Xiaoyao and others are guarding peace, new evil forces are also secretly ready to move. And in this challenging world, how Li Xiaoyao and his friends will continue to write their legend will become a permanent suspense.

In the days when Li Xiaoyao and the others guarded the peace of the Three Realms, they established a strong friendship in the human world, the fairy world, and the demon world. Whenever they encounter difficulties and challenges, they will work hand in hand to face them together. And in the process, they also continue to grow and improve, and each has found their own purpose in life.

Zhao Ling'er became more and more mature, and she gradually took on the responsibility of Nuwa's descendants, cultivating hard, hoping to reach the realm of her mother one day. At the same time, she also takes caring for the weak and spreading justice as her mission, leading Li Xiaoyao and others to seek well-being for the lives of the Three Realms.

After experiencing a series of adventures with Li Xiaoyao and others, Zixuan became more and more brave and determined. She began to devote herself to the study of various spells and martial arts, hoping to one day reach the realm of fighting side by side with Li Xiaoyao and others. And the friendship between her and Li Xiaoyao has also become the driving force for them to jointly protect the Three Realms.

However, the world is always full of unexpected crises. One day, an evil force even more powerful than the "Heavenly Demon" suddenly rose in the Three Realms. This force calls itself the "Demon Realm", and its leader is ambitious and seeks to unify the Three Realms and become the master of the universe.

In the face of this unprecedented crisis, Li Xiaoyao and the others stepped forward again, and they decided to lead the beings of the Three Realms to jointly resist the invasion of the "Demon Realm". After a fierce battle, they finally defeated the leader of the "Demon Realm" and successfully guarded the peace of the Three Realms.

However, they also realized that in order to completely eradicate the evil forces, they must solve the problem at the source. So, Li Xiaoyao and others decided to go deep into the Demon World to find the real reason for the rise of the "Demon World". And this new adventure will bring them more challenges and growth, and will become the most exciting part of their saga.

After entering the Demon Realm, Li Xiaoyao and the others found that the environment here was completely different from the world they were familiar with. The aura of darkness enveloped the entire Demon Realm, and evil forces ran rampant in all directions. In order to find the real reason for the rise of the "Demon Realm", they had to carefully investigate step by step.

In the depths of the Demon Realm, they discover an astonishing secret: it turns out that the leader of the "Demon Realm" was once a demon god named Chi You, who was banished from the Immortal Realm thousands of years ago and posed a serious threat to the Three Realms because of his evil power. However, Chiyou has not been eliminated, he has been looking for opportunities in the Demon Realm, trying to make a comeback and unify the Three Realms.

After learning all this, Li Xiaoyao and the others decided to look for a way to defeat Chi You. After some hard work, they found a legendary immortal magic secret book - "Xuanyuan Sword Technique". This secret book records how to use the power of the Xuanyuan Sword to seal the evil demon god.

In the process of cultivating the Xuanyuan Sword Technique, the strength of Li Xiaoyao and the others has been unprecedentedly improved. They are confidently preparing to start a decisive battle with Chiyou to completely eliminate this evil force that is harming the Three Realms.

Finally, in the center of the Demon Realm, Li Xiaoyao and the others launched an earth-shattering fierce battle with Chi You. In the fierce battle, Li Xiaoyao relied on the power of "Xuanyuan Sword Technique" to successfully seal Chi You and suppress it forever in the depths of the demon world.

Lin Yueru and Anu are in the fairy world, dedicated to researching various magical spells and skills to help the residents of the fairy world solve various problems. Their fame gradually spread in the fairy world and became a role model for many immortals.

In the demon world, Zixuan worked hard to mediate the contradictions between the demon world and the fairy world, so that the dispute between the demon world and the fairy world gradually subsided. With her wisdom and persistence, she has won the respect of the demon world and the fairy world.
