There was no problem at all in the general direction of Zhou Muhai's modified formation layout, Lin Jiu checked it carefully, and took Zhou Muhai to change the position of the next few yuan stones, and then took out a large number of high-grade yuan stones from the bead space and asked Zhou Muhai to select the materials suitable for the formation.

Then Lin Jiu took Lu Shijun to memorize the simple number of all the Yuan Stones, so as to ensure that after she and Xiao Hai laid down the Yuan Stones, Lu Shijun's Demon Yuan could follow them and accurately activate the Yuan Stones in the corresponding positions.

The order of activation of the Yuan Stone is very strict, and there can be no mistakes of one star and a half, but as long as there is no problem with the position, even if it is wrong, you can rewind it again.

Lu Shijun had never been in contact with the study of formations, and Lin Jiu didn't expect him to succeed at one time, after all, the more nervous and stressful he was, the easier it was to make mistakes.

"Ah Jiu, when I return to Huaguo, how about you also teach me the formation?"

Lu Shijun memorized the order one by one in his heart, with his mid-level divine sense in the Yuan Condensation Period, he would not be unable to remember, and Lin Jiu was also concerned about it.

"It's good if you're willing to learn, now there is only one refiner in the Hidden Sect, Lu Shiyi, and there is indeed a lack of someone who specializes in formations...... On the other hand, the Mountain Sect still lacked a disciple who specialized in refining weapons. ”

"Don't worry about this, I see that Zheng Yi's kid has been close to the third child recently, and he happens to be a fire spirit root."

Lu Shijun calmly gave Lin Jiu an idea.

"He is a disciple of the ancestor, and he will be used for Zhenshan in the future...... He is interested in the best, and there is no way to do it. ”

Since ancient times, each sect has only one requirement for Zhenshan Ancestor - to be able to fight. Xuanyi is obviously cultivating Zheng Yi in this direction.

But this is not something that can be done in a day or two, at least before Zheng Yi can take charge alone, Xuanyi has no way to pick a child, unless he wants to be killed early by Tiandao.

mentioned Zheng Yi, and while carefully selecting Yuan Shi, he paused in Zhou Muhai's hand.

"Don't worry, he will want to learn."

Lin Jiu: ???

Lin Jiu just wanted to ask a few more questions, but Zhou Muhai focused on selecting the Yuan Stone again, and Lin Jiu didn't know where his little apprentice came up with such a sentence, so he didn't pay much attention to it.

The things inherited from Xiaoxian Yuan are too rich, and Lin Jiu's achievements in the alchemy formation and talisman seal are remarkable, but he doesn't know anything about refining weapons, and he has to be hard-headed, which is really embarrassing.

Lu Shiyi's alchemy skills have surpassed Lin Jiu's far, if she doesn't hurry up, Lu Shiyi really has nothing to learn.

Lin Jiu's head was big when he thought of this, but he still did the current thing first, while Zhou Muhai had already picked out the suitable materials, Lin Jiu put away the remaining Yuan Shi and took Zhou Muhai to dive into the trench.

Under the curious gaze of Xiaolan Xiaoyin and countless mermaids, the Yuan Stones were accurately embedded in the position specified by the formation, and the Gathering Yuan Array was quite simple, as long as it was completed, it would be able to operate.

The three small Gathering Yuan Arrays were the first to operate, and the rich Demon Yuan gathered in the merfolk's new habitat.

And Xiao Lan Xiaoyin, who had the most complete evolution in the mermaid group, was the first to notice this, and the two of them accurately found the location of the Juyuan Array, and swam around excitedly and worriedly.

The excitement was that he didn't expect that the energy that could help them evolve after leaving the sea puddle could still be gathered, but he was worried that the tragedy of the previous sea pit being besieged would happen again, and he looked at Lin Jiu with puzzled eyes, and Qing Yue, who belonged to the mermaid, had a penetrating voice that was captured by Lin Jiu's divine sense.

Lin Jiu calmed Xiaolan Xiaoyin's uneasiness a little, nodded to Lu Shijun next to him, and his divine sense transmitted.

[Let's start, do you remember the order?] 】

[Well, don't worry. 】

Lu Shijun released his divine sense, and the divine consciousness that had been tempered by the heart refining left by the Venerable on the land was very strong, although it was not easy, but it could be regarded as covering every part of the trench without danger.

Immediately afterward, the abundant Demon Yuan covered every part of the formation along Lu Shijun's extended divine sense, and according to Lin Jiu's simple and easy-to-remember number, the Yuan Stones that formed the formation were activated by Lu Shijun's Demon Yuan in an orderly manner.

The dark light lit up and disappeared in the position of the sea puddle, and a full half an hour passed before Lu Shijun activated all the Yuan Stones that formed the first formation, and then according to Lin Jiu's instructions, he established an energy connection between each Yuan Stone and the Yuan Stone embedded in the deeper part for replacement.

The formation was an instant success, and after it was put into use, the formation emitted a wonderful hum, and even underwater, the three of them and the mermaids could hear it very clearly.

Xiao Lan Xiaoyin swam out of the range of the formation, and when he looked back, he found that a large number of companions in the trench had suddenly disappeared, including the magic yuan energy generated by the Juyuan array.

The two of them were as if they had crossed over, and quickly swam back to the bottom of the sea in the original direction, but they were trapped by the blocking and bewildering formation, and Lin Jiu was in the formation, watching Xiaolan Xiaoyin and Xiaoyin swimming around trapped in a small body of water, looking like they were about to cry.

It seems to be working very well.

Lin Jiu smiled, left the range of the formation, grabbed the two of Xiaolan Xiaoyin, and dragged them into the formation.

Xiao Lan Xiaoyin only felt as if she had passed through a layer of soft obstacles and returned to the formation again.

Feeling the energy that was slowly accumulating, the mermaids of his own race were still in place, and only then did he recover from his panic, and he could be regarded as truly experiencing the magic of the cultivation realm formation.

When the Great Array of the Qianshan Sect was first formed, the disciples relied on the disciple's waist card with Lin Jiu's divine sense mark to be recognized and released by the formation, but the waist card was a foreign object after all, and if it was obtained by someone with ulterior motives, it could still enter the formation.

After waiting for the array plate of the Qianshan Sect to be used, Zhou Muhai specially organized all the disciples to leave their personal divine sense marks on the formation plate, and uniformly banned the divine sense imprints on the waist card to identify the formation, which officially eliminated the possible troubles.

But this group of mermaids is not a monk after all, and in the case of constantly having little mermaids born, it is not convenient for Lin Jiu to leave identification methods such as divine sense imprints, so he can only let Zhou Muhai leave two entrances and exits in the formation.

As long as you follow a specific route and mark to enter the bottom of the trench, you can smoothly come to the territory of the mermaids, Lin Jiu took Xiaolan Xiaoyin back and forth a few times, until the two of them were able to enter and exit the formation without hindrance.

There are two passages, one can be entered and exited daily, and the other is that Zhou Muhai pulled his master and laid down a lot of small attack formations, and on the route of leaving, small stone platforms were raised directly from the bottom of the sea, which was used as a mark.

[Master, once they have been arranged, these markers will disappear when they need a large-scale retreat. 】
