Time flies, Lu Yu has grown up in the fairy world for more than a hundred years.

Recalling that when the fourteen-year-old boy entered the realm of the first immortal, and now he is the leader of the Anti-Investigation Alliance, Lu Yu has indeed matured a lot.

Seeing that the Anti-Investigation Alliance was gradually maturing in operation, with skillful anti-reconnaissance capabilities and amazing combat power, Lu Yu also breathed a sigh of relief for the time being and began to refocus on his own cultivation.

In the past hundred years, Lu Yu has successively read more than 20 volumes of the cultivation secrets handed to him by Master Luo Qi, and he is confident that he has mastered the martial arts techniques and internal strength necessary for cultivating immortals.

However, there is still a long way to go before breaking through to the middle immortal level.

His current aura exhalation level still needs to be improved, which is similar to his senior brother Qiu Lin's fault, that is, because the diagram is fast, and the skill of running the aura is not very stable.

In response to this problem, Luo Qi wrote a secret book of "Reiki Operation Skills" for Lu Xian, and printed an extra copy for Qiu Lin, so that they could study it well and improve it as soon as possible.

Since the Chiyan Demon God joined the Immortal Court, he has also made a lot of contributions to the Immortal Court.

Chiyan served the Immortal Court in several immortal and demon battles, commanding the demon army to defeat the enemy, winning many battles, establishing an excellent reputation for loyalty, and cultivating many handy demon clan troops.

Chiyan felt that before Lu Xian became an Immortal Court Elder and became his unattainable leader, it was time for him Chiyan to apply to Lu Mian to join the Anti-Investigation Alliance.

Although some of the demon clans are still subdued to the demon realm, Chiyan is confident that he will lead the demon clan of the fairy realm to join Lu Xi's camp first. If he has the ability to call on all the demon clans to submit to the Chiyan Banner one day, he will gather the demon clans belonging to the demon world back in a unified manner to achieve a unified demon sect.

The idea of the Chiyan Demon God gradually took shape, and he began to secretly contact the demon clans of the fairy world and persuade them to join the anti-detection alliance. He knew Lu Xi's opinion of the demon clan, and knew that only by letting Lu Yu see the strength and loyalty of the demon clan could he win his trust.

At the same time, Lu Yu was also constantly working hard to cultivate. He spends a lot of time every day studying the "Reiki Operation Technique", trying to solve the problem of his own Reiki exhalation. Although the process was difficult, he firmly believed that as long as he persevered, he would one day break through to the level of a middle immortal.

In addition to cultivation, Lu Yu will also pay attention to the dynamics of the Immortal Court. He learned that the Chiyan Demon God was actively lobbying the demon clan to join the anti-investigation alliance, and he secretly praised it in his heart. He knew that the addition of the Chiyan Demon God would bring great power to the Anti-Detection Alliance, and would also further consolidate the Immortal Court's position in the Immortal Realm.

After another two hundred years, the lobbying work of the Red Rock Demon God has achieved remarkable results. More and more demon clans began to join the anti-investigation alliance, and their strength was recognized by Lu Xi.

The Chiyan Demon God also gradually established his prestige among the demon clan in the process and became the leader in their hearts.

However, at this time, the Demon Realm suddenly launched a large-scale attack. The defense line of the Immortal Court was broken through in an instant, and many immortal generals and demon soldiers fell one after another. Seeing this, Lu Yu immediately led the members of the Anti-Detection Alliance to the front line to support, and they launched fierce battles with the demons one after another.

In this battle, Lu Yu showed amazing strength. Not only did he flexibly use the martial arts techniques taught by Master Luo Qi, but he also successfully broke through to the middle immortal level in battle.

It only took him three hundred and sixty-seven years to break through from the first immortal to the middle immortal level, and he became a mythical existence in the immortal world.

Many monks even got inspiration from this, whether it was possible to break through the cultivation level faster and better by cultivating in more and more arduous training and increasingly severe battles.

Lu Xi's aura breath has become more stable now, and his combat effectiveness has also been greatly improved.

Under the leadership of Lu Yu, the members of the Anti-Reconnaissance Alliance fought bravely to kill the enemy and successfully repelled hundreds of attacks from the Demon Realm. As a result, when the demon army withdrew from the immortal realm, there were only a few generals left, and their vitality was greatly damaged. It is worth noting that among the remaining demon armies is the demon king Poyu, who cannot be killed.

After the war, Lu Yu had an in-depth conversation with the Chiyan Demon God.

Together, they discussed how to further strengthen the Immortal Court's defenses, and how to better use the power of the Demon Clan to fight against the Demon Realm.

The Chiyan Demon God also expressed his willingness to fully support Lu Yu and contribute his strength to the Immortal Court and the Anti-Investigation Alliance.

After several alliances, the relationship between Lu Yu and the Chiyan Demon God became closer and closer. Together, they led the members of the Immortal Court and the Anti-Detection Alliance to constantly resist the attacks of the Demon Realm. Under their leadership, the Immortal Court gradually grew and became one of the most powerful forces in the Immortal Realm.

And the names of Lu Yu and Chiyan Demon God have also become legendary existences in the fairy world. They not only broke people's stereotypes about the demon clan with their strength and achievements, but also broke through the barrier between humans and demons, so that the two clans could fight side by side, and even become close friends in life and death.

In the years that followed, Lu Yu and the Chiyan Demon God jointly guarded the peace of the fairy world.

They lead the members of the Anti-Investigation Alliance, constantly cultivating and improving their strength to deal with possible crises.

At the same time, they are also actively looking for a way to completely destroy the Demon Realm.

By chance, Lu Yu found an ancient book in the library of the fairy world, which recorded a mysterious exercise called "Heaven and Earth Return to One".

It is said that this exercise can fuse the power of the two races, the immortals and demons, and perfectly fuse the two, thus releasing powerful energy.

Lu Yu and the Red Rock Demon God both took a keen interest in this text, and they decided to practice this mysterious technique together.

In the process of cultivation, Lu Yu and the Chiyan Demon God encountered many difficulties and challenges. But with their firm belief and unremitting efforts, they finally succeeded in perfectly fusing the power of the immortals and demons, releasing amazing energy.

They joined forces to perform the "Heaven and Earth Are One" technique, successfully sealing the entrance to the Demon Realm, and completely eliminating the threat of the Demon Realm to the Immortal Realm.

However, the unexpected always comes before the plan, and it is always so unexpected.

Just when the Demon Realm was completely sealed by the "Heaven and Earth Are One" exercise, several remnants of the demon clan actually escaped in the cracks, and one of the demons seriously injured Xue Ziyan beside Lu Yu with a blow of destruction under Lu Mi's nose, and that demon also died in his destructive move.
