That's right, these people are Luya, who is looking for people all over the place, and Doya's group who are returning from going out.

From Su Yu's point of view, they appeared out of thin air, and from Luya's point of view, Su Yu also appeared suddenly.

Obviously, the place where she was standing just now was an open space, and there was nothing, but she was just playing a big change in front of everyone.

"I'm fine, you guys calm down first, I have a major discovery." Su Yu knew that they were worried about themselves, but the matter of the formation was obviously more important, so Su Yu didn't care if there were other people around, or other people's eyes and ears, and directly said the matter of the formation.

Anyway, she can see that these people have made a lot of noise in order to find her, and even if they don't say it now, they will be known sooner or later, so she has no need to hide it.

"There are two formations here, one of which is the ...... of the Huimen Formation" After some explanation, except for Su Yu's own people and Luya, others were somewhat skeptical of Su Yu's words.

After all, how could a water dungeon, a place where birds don't, come out of a formation inexplicably?

And it's two formations!

Not to mention whether anyone was able to break through the guards and come to the water prison, no one could think of what the meaning of this arrangement was.

It can't be that someone is idle and panicked and wants to arrange a formation to play, right?

But they had indeed seen the magical scene of the Great Transformation of the Living People with their own eyes just now, and apart from the formation in Su Yu's mouth, they really couldn't think of any other possibilities for a while.

"Lua, do you know if you merfolk have anyone who is proficient in formations?" Although Su Yu also knows a lot about the formation, her understanding is based on the information that has been made public before.

But this time it was a self-created formation that had never been made public, so Su Yu couldn't do anything about it.

And among the people she brought with her on this trip, there were obviously no ones who were proficient in formations, so they could only seek foreign aid in this matter.

However, since this is the territory of the mermaid clan, there is a formation on their territory, and it has not been discovered for so long, she always feels that this is not done by the mermaid, it should be a long time ago, the formation left by a mermaid, but it has not been known.

"Formation ......" Luya thought for a moment, and then showed embarrassment: "Yuzu, there is indeed an elder in our clan who is proficient in formation, but this elder has a bad relationship with me. ”

The elder in Luya's mouth is actually the second elder.

It doesn't matter if the second elder is good or bad, but his strength is not low, after all, he needs to maintain the protective cover of the mermaid clan, and his strength cannot be bad.

And because the protective shield is actually composed of multiple formations, the second elders of the past dynasties are actually formation masters.

The merfolk are similar to the elves in this regard, their elders do not have a clear hierarchy of status, and their order is only related to their duties.

For example, the Great Elder is responsible for managing and coordinating the elders, assisting the Mermaid King in managing the Mermaid Clan; The second elder needs to be proficient in the formation and is responsible for maintaining and repairing the protective shield of the mermaid clan; The Third Elder and the Fourth Elder are in charge of the security of the Mermaid Clan, and all kinds of guards and guards of the Merfolk Clan are trained from them; The Fifth Elder and the Sixth Elder are in charge of the resource management of the Mermaid Clan, and the two of them have the keys to the Merfolk Clan's treasure house in their hands.

Hearing Luya say this, Su Yu had a slight impression of this second elder.

Because this elder seems to be the only one Lua doesn't often mention, it is estimated that this is also related to what she said about the bad relationship.

However, after finally discovering the clues, Su Yu naturally would not give up easily.

And whether the relationship is good or not is actually not the point, because this matter is not Luya's personal matter, but a major event related to the safety of the entire mermaid clan!

"Luya, it doesn't matter what you said, you just need to think about whether this second elder is loyal to the merfolk clan." As long as the second elder is loyal to the mermaid clan, then all the grievances between him and Lua can be put aside first.

Su Yu believes that Luya is not ignorant, and she must know which is more important than the personal grievances and the safety of the entire race.

"I see." Luya also knew that she was thinking too much, and it was not a personal grudge that she had to consider at this time.

According to their previous guesses, the men wanted her to put Harry in the water prison, so they went to the water prison to check it out.

As it turned out, the water prison was indeed problematic.

In this case, the problems in this water prison must be part of the mermaid plan......

They finally discovered the problem first, but they couldn't let go of this opportunity.

"In this kind of big thing, I naturally believe in the second elder's ......" The reason is very simple, if the second elder is an inner ghost, then the fish-man doesn't need to do so many things secretly at all.

They directly asked the Second Elder to close the protective cover of the merfolk clan, and then the merfolk clan would naturally be in a mess, which was much easier than painstakingly placing pollution in the forbidden land.

"Since it can be trusted, the matter of the formation will be handled by the second elder...... Luya, what do you think? Su Yu looked at Luya and asked.

Luya nodded, then turned to the person behind her and ordered, "You go and invite the second elder, just say that it is a big matter related to the safety of the mermaid clan, and let the second elder come over." ”

During the time she went to invite the second elder, Su Yu talked about the formation in detail, and when she heard Luya say that she had also found many holes in the water prison, she asked her to take the marked drawings to herself.

Because he already had the experience of finding the first formation, Su Yu simply looked at the drawings on Luya's side and directly found the location of the formation.

"That's supposed to be four...... No, these should be two formations that correspond to each other, and cracking the formation must be carried out at the same time, otherwise there will only be failure. "The reason why it is said that there are two formations that correspond to each other is because these two return formations do not correspond, otherwise it would be impossible for her to unravel.

After understanding this, Su Yu knew why she couldn't crack the unknown formation just now, because she only saw one of the formations, but not the other...... Questions that are not well qualified will certainly not be answered.

"Let's go find another formation first." Although he had already asked people to find the second elder, if he could solve the formation one step ahead of time, he would be able to know more quickly what secret this formation was hiding.

But before that, Su Yu first asked Luya about the whole process when she was inspecting the water prison.

Because if there are formations on both sides, then why only Su Yu entered the formation by mistake, but nothing happened on Luya's side?
