Lu Yi finally sent Xin Tong to return to the sinkhole accompanied by Xu Yining, while picking up the relics left by the black madman, while mobilizing some more people from the sinkhole, after the troops were divided into multiple ways to move the troops, he himself was not idle, and began to take others to set up defenses on the island. The first is to arrange a large maze, because the rocks of that island are relatively special, although the material is not high, barely reaching the fourth order, but it can absorb a certain amount of spiritual power, which can be said to be the best choice for laying out the maze illusion array, and Lu Yi happens to like to arrange this kind of magic circle, which is also the reason why he resolutely gave up the other islands where the stone is better than here after careful selection. The maze array that Lu Yi arranged this time was an ancient array that had been modified with the help of the water potential of the Chaos Sea, called the "Dehydration Wave Maze Array". It mainly relies on the continuous flow of water vapor from the Chaos Sea to cover the entire island, whether it is water vapor or the rocks on the island, it can absorb and mislead the spiritual power, causing the intruder to have a perceptual bias. And it can use the current to lure intruders who strayed into it to the outside of the island or even to a specific location, so as to capture them or kill them directly.

In addition to arranging the formation, Lu Yi also plans to build a fortress on that small island, all the materials used on this island are the star stones that Lu Yi carried from the Western Regions Spirit Star Country, this fortress is built as the last defensive backbone, not only is it hard, but the defensive array it lays is also the most advanced, because Lu Yi saw from the black man's last letter that the other party also found a formation mage, and it seems that the level is not low.

Time is relatively tight, after the bounty is released, under the stimulation of the treasure, it will definitely cause the monks to go crazy, maybe there will be news soon, and even more unpredictable things will happen, and Lu Yi left the contact location for the Wanda Mansion at that time is here, as long as someone has news confirmed, they will be guided here by the people of the Wanda Mansion. Therefore, Lu Yi's first task was to quickly establish the Deshui Xingbo Fan Divine Array to prevent his side from being caught off guard. Therefore, in order to be able to take a multi-pronged approach, this time to build a defensive fortress on the island, the spirit building bosses who have not done it for many years have spared no effort to take action in person. How can the effect of the building in the hands of the spiritual monk be extraordinary? When the glorious three-story fortress stood on the small island, even Lu Yi was surprised that he couldn't close his mouth for a long time.

This is a super fortress built by the collective wisdom and experience of more than a dozen spiritual monks, although it is not large, only an area of less than a thousand feet, but it is very exquisitely designed, the height of the city wall, the thickness of the wall, and even every corner and every window are all carefully deduced, all from the perspective of defending against the attack of the spiritual monk level. Such a fortress itself already has excellent ability to resist attacks, and if it is supplemented by a clever defensive array, it is really impregnable, so after Lu Yi was amazed, he began to rack his brains to design a magic circle for this fortress that matched it.

In Lu Yi's cognition, it was no longer possible to find a magic circle that could match it, and even a formation like Venerable Li Tian couldn't think of what kind of magic array could be arranged with Lu Yi's ability to add icing on the cake to this fortress.

However, time did not allow the old and the young to study it more closely, because soon someone came to the door. The first person who came to the door was a monk in the early stage of spiritual building, who was known as Changji Zhenren, and was a casual cultivator. According to his description, more than 120 years ago, he once encountered a fierce battle in the place near the Eastern Regions in the Night Mountain Forest, and the two sides were all spiritual monks, and the difference in numbers was huge, with only two on one side, one for a group of mages from the dark monks, and as many as six on the other side. Out of self-preservation, he didn't lean over to take a closer look, but avoided it from a distance, and now after Lu Yi issued a reward, he realized that it might be the people from the warring sides he saw back then, so he went to Wanda Mansion to try his luck. As a result, he saw that the person was the black and white elder, so Wanda Mansion conveniently asked him to come to Lu Yi with a token.

After listening to what this person said, although he did see the black and white elders back then, but after so much time, he couldn't find someone, so he only gave him a spirit stone as an information fee. Lu Yi didn't let this Changji real person land on the island, he didn't want to expose his layout in front of a stranger, and this person didn't know if it was a spy sent by the enemy family after receiving the news.

With the beginning of this Changji real person, some people have provided some clues one after another, and the timeline is gradually approaching the present, and the location is uncertain, both in the town to meet the black and white two elders, and to see the black and white two elders fighting with people, gradually, as some confirmed details are gradually exposed, a black and white two elders' action trajectory map in recent years has been slowly outlined.
