This matter has to start with the protection of Feiyan City. Lu Yi once asked Mingzi who built the wall of Feiyan City and who blessed the magic circle. Mingzi told Lu Yi that the wall had already existed here before the Justice Alliance came. It is said that the forces entrenched in Feiyan City worked together to build it. Those forces also jointly hired a formation master to arrange this magic circle, intending to occupy Feiyan City for a long time. However, the formation master they hired was really not very good, and the method they arranged it

The formation was okay to fool these laymen, but he took the money and ran away early, without any subsequent maintenance. Over time, the magic circle began to show various flaws, which also brought conflicts to several forces. They complained and accused each other, and the rift became bigger and bigger. In the end, the Justice League took advantage of the opportunity to enter Feiyan City and seized the Feiyan City. After the Justice League took Feiyan City, the magic circle was repaired, but there was no decent formation master in the league, only Akiko and the other one.

A fifth-level formation master was barely reasonable, so they used what they learned to repair and strengthen the magic circle, so that the magic circle would maintain normal operation. Another formation master was a cultivator in the early stage of spirit building. He had not been in Feiyan City for this period, but went out to find a suitable magic circle or see if he could invite a high-level formation master to improve the magic circle. Two days ago, the formation master came back and he sold it at a auction at a large price.

A set of sixth-level magic array formation maps rushed back to Feiyan City on a long journey, hoping to improve the city defense. However, when he came back, he found that he was still not able to understand the sixth-level magic array thoroughly. Moreover, if he wanted to arrange the sixth-level magic array, the original defensive magic array had to be completely abandoned. Although the Justice League did not invest too much in the original magic array, they were used to poor life and were still a little reluctant to let it go, so they thought of asking Lu Yi for help to see if they could take care of it.

Lu Yi originally planned to intervene in the affairs of the Justice League as a formation master. Now he doesn't have to find an opportunity by himself. The other party actually fell into trouble first. He definitely couldn't miss such a good opportunity. However, Lu Yi still put on airs. He did not go to the Justice League, but asked them to bring the formation map to his own courtyard. In addition to Mingzi's father, the fifth-level Formation Master of the Spirit Building Stage also came together. Needless to ask, he must be here to test Lu Yi's true level.

After some politeness, Lu Yi took the jade slip that recorded the formation map from the formation mage. When he looked at it roughly, he frowned. Lu Yi said to the formation mage: "Don't you know that this is a water-based defense magic array? Such a formation is arranged here, not to mention the effectiveness, just this consumption, how can a small force like you, such as a scattered person, bear it?"

The man looked a little embarrassed, "Mr. Lu is indeed as wise as a torch. This array map is indeed a water-based magic array. In fact, there is nothing we can do about it. Nowadays, the mainland is in a hot spot because of the demon clan. Many things are priceless under the soaring prices. This advanced magic array is even more popular and is often snatched up as soon as it appears. It is already a great blessing that I can grab this thing, so how can I be too picky!"

This person's words are true. In normal times, the sixth-level formation map is already a very competitive good thing. Now the situation on the mainland is severe, and various forces are preparing for war. This kind of thing has long reached the height of strategic materials, so it is naturally even more popular.

Lu Yi returned the formation diagram to the other party, "You ask me for help, just to improve the defense ability of Feiyan City. This matter is actually easy to deal with. If you transform the original magic array, the effect of the improvement is already very obvious. There is no need to re-made more advanced ones. Save this big cost. You can use them to do more meaningful things. Give me a few days, and I will come up with a suitable plan. At that time, I will ask Akiko to notify you that we will carry out a transformation of Feiyan City's city defense together."

With Lu Yi's words, although he had not yet fully understood Lu Yi's ability and his true identity, he dared not be completely relieved of Lu Yi, but to get Lu Yi's help, it would be better to treat dead horses as living horses first than to be helpless. So Mingzi's father said goodbye to the formation master and left. Lu Yi took Mingzi to the wall of Feiyan City and began to conduct on-site investigation. Lu Yi walked around Feiyan City for a few times, and then returned to his residence to meditate. Five days later, Lu Yi asked Mingzi to send her father, saying that the renovation plan had been designed and the people of the Justice League came to discuss.

The Justice League obviously had been waiting for a long time, so not long after Akiko sent a message, the old guys from the Justice League all came to Hulala, waiting to hear Lu Yi's insightful views.

Lu Yi didn't expect that so many people would come to him, which scared him himself. But this is fine, Lu Yi could make them fully realize their value. Lu Yi waved his hand and formed a spiritual light curtain in the air. On it was a complete picture of the magic array arranged on the outer wall of Feiyan City. Lu Yi began to tell everyone about the design ideas of the formation master who designed this formation, pointed out the flaws and loopholes of the magic array one by one, and came up with corresponding transformation plans. After Lu Yi's explanation for a long time, basically all the people present had understood Lu Yi's meaning, and the fifth-level formation master who built the spirit was also deeply impressed by Lu Yi.

Lu Yi explained his transformation plan from beginning to end and asked the fifth-level formation master, "Do you understand everything?"

"I understand, I understand! Mr. Lu's formation is indeed very clever. I admire him, I admire him!" The man had completely recognized Lu Yi's formation level this time.
