During a sneak trip, Lu Yu accidentally discovered a superweapon that the Demon Realm was secretly developing, a giant aircraft carrier. This aircraft carrier is equipped with a large number of magic weapons, and the design is ingenious and intricate, which is breathtaking. He knew that this discovery was of great significance to the Immortal Court, so he quickly returned to the Immortal Court and reported this important information.

The high-ranking officials of the Immortal Court were shocked by this news, and they immediately summoned various forces to discuss countermeasures. In the process of discussion, Xue Ziyan proposed a bold plan: send someone to secretly infiltrate the demon realm and dismantle the aircraft carrier. She believes that this aircraft carrier is an important weapon of the Demon Realm, and once it is destroyed, it will greatly weaken the combat effectiveness of the Demon Realm and gain more advantages for the Immortal Court.

The members of the Anti-Reconnaissance Alliance received this task, and they immediately went into action. They use their stealth skills to quietly infiltrate the Demon Realm to find traces of the aircraft carrier. After many difficulties, they finally found the docking place of the aircraft carrier and began the demolition operation. They worked together to quickly and accurately destroy the key parts of the aircraft carrier, and finally succeeded in dismantling the giant aircraft carrier.

The success of this operation not only weakened the combat power of the Demon Realm, but also won valuable time and opportunities for the Immortal Court. The members of the Anti-Investigation Alliance showed their courage and wisdom, and made great achievements for the victory of the Immortal Court.

When Yun Ji learned that the aircraft carrier had been dismantled, he became angry and wanted to find an opportunity to confront Lu Xi again, waiting for an opportunity to get rid of Lu Xi.

After Lu Yu learned of Yun Ji's intentions, he decided to strike first, he knew that Yun Ji was cunning and ruthless, and he must take action as soon as possible. So, he contacted the members of the Anti-Reconnaissance Alliance and formulated a careful plan to eradicate Yun Ji before he could do it.

They took advantage of Yun Ji's style of action to predict his course of action and set up an ambush in his path. When Yun Ji passed by alone, the members of the Anti-Detection Alliance suddenly appeared and surrounded him. Yun Ji was shocked when he saw this and tried to resist, but the strength of the team members was too strong, and he was quickly subdued.

Lu Yu walked up to Yun Ji, looked at him coldly and said, "Yun Ji, do you think you can escape my control?" Your ambition and ruthlessness have already doomed you to failure. Yun Ji struggled to get up, but was firmly held down by the team members. There was a hint of fierceness in his eyes, but he couldn't change it.

Lu Yu didn't pay any more attention to Yun Ji, he turned to the team and said, "Take him back to the Immortal Court and let the higher-ups decide what to do." The team members nodded yes, and then escorted Yun Ji back to the Immortal Court.

Xianting first put Yun Ji in the heavenly prison and sent heavy troops to handle it. Then, Immortal Emperor Xue Cheng rewarded Lu Yu with a valuable reward and gave him a 5,000-year-old Immortal Cave Mansion and 100,000 taels of immortal coins.

Lu Yu received the reward and came to the prison.

When he saw Yun Ji lying down in a dejected position and being restrained in his cell by four thick and heavy Xuantie Immortal Ropes, his heart couldn't help but be deeply touched.

This truth of becoming a king and defeating a thief has made many people sigh about the twilight of heroes since ancient times, and how many heroes have broken their hearts and intestines.

Lu Yu heard that Yun Ji was also a general in the Demon Realm, and now that he was defeated in his own hands, he was also to blame. Although the positions of the two worlds of immortals and demons are different, the disputes in recent years have arisen because of Yun Ji.

"He always wants to kill me, if he doesn't get rid of this demon, it's hard to solve the hidden danger in my heart!" Lu Yu roared angrily in his heart, silently left Yun Ji's cell, and secretly thought about how to find an opportunity to strike first and simply kill Yun Ji.

Lu Yu returned to the dormitory of the Zen Yun Sect, read his notes at night, and unconsciously fell into deep contemplation.

"If the Immortal Court refuses to kill Yun Ji, what should I do? I can't let him go with a huge hidden danger. He has sent people to assassinate me more than 100 times, and if I don't seize this opportunity to get rid of him, I will definitely lay a lot of danger for myself. In the future, I may not have such a good opportunity. Lu Yu groaned.

Thinking that in the past ten years, the Immortal Realm Anti-Investigation Alliance he founded has wiped out all the remaining demon undercover agents in the Immortal Realm. If Yun Ji dies, he can also take a breath for a while.

Lu Xi's thoughts gradually became clearer, and he knew that he had to make a decision. He couldn't let Yun Ji continue to stay in the Immortal Court and become a hidden danger in his heart. However, he also knew that it would not be easy to get rid of Yun Ji, and he had to have a careful plan.

As a result, Lu Yu began to secretly contact his cronies to discuss countermeasures. They decided to take action on the way Yun Ji was escorted back to the Immortal Court to participate in the trial, so as not to cause unnecessary trouble in the heavenly prison.

Lu Yu carefully selected a group of elite team members, all of whom are leaders in the anti-investigation alliance, and they are good at stealth and assassination. They lay in ambush in advance on the way to escort Yun Ji, waiting for the time to come.

Finally, at the end of night, the team escorting Yun Ji came slowly. Lu Yu and his team members acted quickly, subdued all the escorted immortal soldiers with lightning speed, and then dragged Yun Ji out of the prisoner car.

Yun Ji was stunned by the sudden change, and he struggled to resist, but was firmly controlled by Lu Xi's teammates. Lu Yu walked up to Yun Ji and said coldly: "Yun Ji, your end has come. ”

After speaking, he waved his hand, and the team members immediately took Yun Ji to a remote place. There, they used the most brutal way to execute Yun Ji by dividing the body of five horses, paying the due price for his ambition and ruthlessness.

Afterwards, Lu Xi handled the whole incident cleanly and neatly, leaving no traces. Although the high-level officials of the Immortal Court were suspicious, they could not find conclusive evidence. And Lu Yu continued to play his role in the immortal court, contributing his own strength to the peace and stability of the immortal world.

As time passed, Lu Xi's prestige and status gradually increased, and he became an indispensable member of the Immortal Court. His anti-detection alliance also grew stronger and stronger, becoming one of the most powerful intelligence organizations in the fairy world.

However, although Yun Ji's death temporarily freed Lu Yu from the great trouble in his heart, he knew that the struggle between the two worlds of immortals and demons was not over. In the Immortal Court, there are still many demons who break into the undercover and lurk from time to time, ready to provoke new conflicts.

Lu Yu understood that if he wanted to maintain the peace of the fairy world, he must continue to strengthen the strength of the anti-investigation alliance, increase vigilance, and constantly eradicate potential threats.

He began to actively search for and cultivate new members of the Anti-Investigation Alliance in the Immortal Court, not only limited to people in the Immortal Realm, but also began to select potential young monks from the mortal world, and secretly brought them into the Immortal Court for strict training and assessment. Lu Yu knows very well that an excellent intelligence officer not only needs strong strength, but also needs keen insight and firm conviction.

At the same time, he also began to make secret contacts with other immortal forces, seeking cooperation and alliances. He understands that only by uniting can we jointly resist the invasion of demons and maintain the peace and tranquility of the fairy world.

With Lu Xi's efforts, the Anti-Investigation Alliance has gradually become a force to be reckoned with in the Immortal Court. Not only did they succeed in eradicating many demon undercover agents, but they also thwarted the demons' offensive plans many times. Lu Xi's name has gradually spread in the fairy world, and he has become a hero and legend in people's mouths.

However, Lu Yu was not complacent, he knew that his mission was not yet complete. He will continue to lead the anti-investigation alliance and strive for the tranquility and stability of the fairy world.

The news of Yun Ji's death gradually spread in the Demon Realm, causing strong resentment and dissatisfaction in the Demon Realm.

There were even many demons who began to discuss besieging the immortal realm to get justice for their dead general, Yun Ji. But they didn't dare to act rashly, firstly, the dragons were leaderless, and secondly, they were also afraid of the strength of the Lu Yu Anti-Investigation Alliance and the prestige of the Immortal Court.

There is no demon emperor in the demon world who can stand up and scold the world, but there are a few demon kings who dominate several groups of forces on all sides, forming a situation of oligarchic separation.

One of the famous Great Demon Kings is Poyu.

Po Yu is an extremely ambitious and powerful demon king, who has been secretly accumulating strength, waiting for a suitable opportunity to launch an all-out war against the fairy world. He knew that Yun Ji's death was a huge blow to the Demon Realm, but he also knew that hatred and anger alone could not defeat the Immortal Realm. He needed to find an opportunity that would allow him to unite all the demon forces and fight against the fairy world together.

By chance, Po Yu learned of the existence of the Lu Yu Anti-Investigation Alliance. He immediately realized that this was a perfect opportunity that would allow him to break through the Immortal Realm's defenses and achieve the unification of the Demon Realm. So, he began to secretly send his subordinates to infiltrate the fairy world and collect all the information about the anti-detection alliance.

At the same time, Lu Yu also sensed the abnormal movement of the Demon Realm. He understood that the Demon Realm was secretly accumulating strength and was preparing to wage an all-out war against the Immortal Realm. In order to deal with the impending crisis, he began to strengthen the training and equipment of the Anti-Detection Alliance, increase vigilance, and closely monitor the movements of the Demon Realm.

At this moment, a shocking news came: Po Yu personally led a huge demon army to cross the border between the two worlds of immortals and demons, and approached the core of the immortal world. The higher-ups of the Immortal Court were shocked, they had never imagined that the Demon Realm would launch such a blatant attack. And Lu Yu knew that this was the moment for him to show the strength of the anti-detection alliance and defend the fairy world.

He quickly mobilized all the forces of the Anti-Detection Alliance and launched a fierce battle with the demon army. In this thrilling battle, Lu Mian showed his outstanding command skills and strong strength. He led the members of the Anti-Reconnaissance Alliance to fight to the death against the demon army, attacking and retreating the demon army again and again.

However, Poyu is not an idle person. He is well aware of Lu Xi's strength and resourcefulness, so he is also secretly arranging and trying to find the weakness of the anti-detection alliance. During a night attack, Po Yu successfully captured an important member of the Anti-Reconnaissance Alliance, and used it as a threat to force Lu to comply.

In the face of this sudden change, Lu Yu did not panic. He knew that this was his moment of wisdom and courage. He quickly formulated a detailed rescue plan and personally led a capable team to infiltrate the demon camp. After a fierce battle, they succeeded in rescuing the captured members of the Anti-Reconnaissance Alliance, and destroyed the command center of the Demon Army, killing hundreds of Demon Clans.

In this battle, the anti-reconnaissance alliance won a major victory. Demon King Poyu's ambitions and plans this time were heavily crushed, and the demon army was forced to withdraw to the Demon Realm.

The high-level officials of the Immortal Court were amazed by the strength and courage of Lu Yu and the Anti-Investigation Alliance, and they knew that it was with such a group of brave and fearless warriors that the Immortal Realm could be peaceful and stable.

And Lu Yu also knows that this victory is only temporary. He understood that as long as the contradictions and struggles between the two worlds of immortals and demons existed, war would never be avoided. Therefore, he decided to continue to strengthen the strength and influence of the Anti-Investigation Alliance and contribute his strength to the tranquility and stability of the fairy world.
