Contradicting the royal family, this is actually a very irrational behavior in the mermaid clan.

But Harry chose to speak out when Lua said that for the sake of Su Yu's face and the punishment would be lenient, either because he was really tenacious, or he felt that the result of doing so would be better than falling into the hands of Luya and being punished.

"Lua, this matter is about your reputation, you better have someone to find out." As a member of the merfolk royal family, there are means and actions that are ruthless and decisive, which is not a problem, but this is based on the premise that the punishment is reasonable.

Luya's favor is a well-known thing, and Su Yu's biggest fear is that someone will take advantage of this to ruin her reputation by portraying Lua as a savage princess who is coquettish and willful, and unreasonable at all.

Water can carry a boat and also capsize a boat, any person with a high status today is held up by the people below, if it loses the support of the people, then it is nothing.

Of course, Su Yu hoped that she was thinking too much, but since she found out the problem, she must have to remind Luya.

Especially now that it is still an eventful season, the matter of the fish-man is imminent, and there must be no problems on Luya's side.

"Yuzu! I see what you mean! "Luya is not stupid, on the contrary, she can make good use of the favor of the mermaid king, constantly seek corresponding benefits for herself, and can maintain this favor and not let it disappear, she is actually not so stupid and sweet as she seems on the surface.

It's just that no matter what you want to do every time, you have to think about it carefully, which is undoubtedly very tiring, and Luya was pampered and grew up, so she is greedy and still hopes that she can become the carefree little princess she was originally.

Therefore, she always shows a different image in front of Su Yu, which is actually her disguise in the face of the living.

"It's good that you understand, I hope this matter is just me thinking too much, it's just that I'm worrying about it......" Speaking of this, Su Yu saw Harry who was going and returning, and also saw the two mermaids behind him, she turned her head and said a few words to Luya, and then the red Si next to Lua took her to Luya's palace.

After arriving at the palace, Su Yu saw the others who had already settled down, and everyone rested for a while, and then Su Yu began to ask Hong Si about the environment and situation around the mermaid clan.

"The layout of the mermaid clan is circular as a whole, the palace is located in the center, surrounded by the residences of ordinary mermaids, and the outermost periphery is a protective cover...... I don't know if it was because he received Luya's order, so Hong Si can be said to have questions and answers to Su Yu.

Even if there was some information that ordinary people didn't know, she didn't keep telling Su Yu.

"Is there anything special about the merfolk due east?" After understanding the general layout of the mermaid clan, Su Yu began to analyze the places where the source of pollution might be hidden according to the information he knew.

Although the west is the direction of the fishman's attack, the fishman's attack can be defended, but the pollution is different, this is irreversible, and it will also most directly harm the mermaid clan, so in the case of limited time, Su Yu must give priority to dealing with pollution.

Hong thought for a moment, and there was a hint of hesitation on her face, but then she thought of what Her Highness had commanded, no matter what question the human in front of her asked, she would answer it truthfully...... Although she didn't know why Her Highness trusted this human so much, and she didn't know what had happened to the merfolk recently, she still decided to listen to His Highness.

"If you're right, due east is actually a forbidden place for merfolk." As soon as these words came out, Su Yu could be regarded as knowing why Hongsi, who knew everything just now, hesitated.

In a place like the forbidden land, it is true that not everyone can tell her, and she is just an ordinary mermaid, but she is more trusted by Luya, so she naturally has no right to tell others about it, especially Su Yu is not a mermaid.

But she said it anyway, so it only shows that Lua did have something to tell in advance.

"Luya told you to do that, right?"

"Yes, Your Highness said, no matter what you ask, I can answer directly."

Su Yu actually asked casually, after all, this is all an obvious matter.

What she cares about most now is this forbidden place...... Why is the forbidden land just due east?

And pollution is also in this direction......

Is it ......?

"That's a bit of a trick to do...... Su Yu didn't think about how the fish-people put the pollution into the forbidden land, because it was basically a fact, and there was no point in dwelling on the problem.

The biggest problem now is that the fish-people can put the pollution into the forbidden land, which is the most important location of the merfolk people, and even if they know that there is pollution inside, they can't go in and deal with it.

No wonder......

No wonder pollution has invaded the merfolk for so long, but no one has found it, it turns out that it is because of the special location.

"Who in the clan generally has the right to enter the forbidden land?" No matter what, Su Yu felt that it was necessary for her to take someone to the forbidden land, even if she had no way to take someone, but she was alone, she had to go.

But before she could do that, she had to find out who could enter and leave the forbidden area, so that she could find out who she could call for help and to rule out the culprit of the contamination.

"The forbidden land cannot be entered, even if it is the king, and the forbidden land cannot be entered, because there is a formation outside the forbidden land, and this formation can only be solved by the elders, and it requires the participation of multiple elders to solve it." Hongsi's words made Su Yu fall into deep thought.

The Mermaid King can't enter the forbidden land, and there is a formation in the forbidden land, and multiple elders need to remove the formation...... No matter how you look at it, it looks like a classic murder in a closed room.

Su Yu knew that it was a 'murder', but this was a 'secret room'.

Unless many of the elders of the merfolk clan are corrupted and bought by the merfolk...... But is it possible?

If so many elders were bought, where did the merfolk still need to be so secretive, they could directly let these elders disintegrate the merfolk clan from the inside, although it took a long time, but it didn't cost a single soldier, and the time they buried the pollution for so long was enough for them to do a lot of things.

"How do you know these things? What Luya told you? Su Yu was still thinking about the forbidden land, but halfway through it, she suddenly discovered a problem - Hong Si knew too many things.

Although Lua makes Red know everything, it is based on Red knowing the answer.

The previous questions were all superficial, as a confidant and playmate of the sixth princess, she had lived in the palace since she was a child, so it was not strange to know this.

But about the forbidden land, how did she, an ordinary mermaid who is not a royal family, know about it?
