Lu Ya didn't think much about it, but thought that the five elders were finally willing to let themselves go to exercise, but Su Yu heard a kind of 'trust' in the tone of the five elders.

To be honest, if Lua was really willing to go to Sunset Territory, Su Yu would definitely welcome it, but the situation of the merfolk was not so bad...... However, Su Yu didn't say anything about it, after all, there are many people here, and no one knows if there are any undercover fishmen among so many mermaids.

"Fifth Elder, don't worry, Luya is my friend, and I will naturally take care of her." Suyu gave a promise, and then took Luya and her own people to the forbidden land.

As for the battle between the merfolk and the fishmen, tonight should be the finale.

In this kind of critical battle, Su Yu can't help much, if they are allowed to stay, not only will they not be able to help, but they may also be in danger.

The crisis of the merfolk can only be solved by themselves.

In two days, Su Yu thought that she had already done what she had to do, and the rest was up to them.

……

……

"Yuzu, aren't you going to the forbidden land? This direction seems to be ...... Water dungeon? Luya looked at Su Yu in a puzzled tone.

Since Su Yu was already going to take Luya to the forbidden land, she naturally wouldn't hide it, so she told Luya about the underground passage leading to the forbidden place in the water prison.

"Huh? How is this possible! Luya's first reaction was definitely not to believe it, but it wasn't that she didn't believe Su Yu, but she really felt that this was unlikely.

The reason is very simple, first of all, if the passage covered by the water prison formation is forbidden, but how could the second elder be that bland performance?

Secondly, there were other passages in the forbidden land, how could the elders not find out?

"I know you think it's incredible, and to be honest, I didn't believe it at first...... But ......" Su Yu thought about it, and finally didn't tell her about Miriel directly, it was too complicated, and she couldn't explain it clearly for a while: "I'll know when you go." ”

Since Su Yu said so, Luya could only suppress her inner curiosity and followed Su Yu to the water prison...... She has a good impression of Su Yu, and she will not doubt that Su Yu will do anything bad to her, which can be regarded as saving Su Yu's explanation and persuasion.

Come to the water dungeon, enter the passage, find the entrance to the forbidden land, and enter the forbidden land.

In less than a day, they came to this place again.

"Yikes! There are so many shark beads here! Lua felt the thick and familiar energy around her, and subconsciously exclaimed.

Then, Lua realizes where she has been, and the surprise in her heart gradually disappears.

This is a forbidden place, a place to bury mermaids and shark beads, isn't it normal for her to feel so many shark beads?

"Look, I'm not wrong, this is the forbidden land." Su Yu was also wondering if this space was a fake forbidden place created by Koyena to resurrect Miriel, but looking at Luya's reaction, she knew that this was indeed a 'forbidden place', but it was not a 'forbidden place'.

After all, even if Koyena wanted to resurrect Miriel again, it would be impossible for her to dig up the shark beads and place them in a new space.

This is undoubtedly using the energy of a dead mermaid to resurrect Miriel, which is obviously not appropriate.

Luya didn't see Su Yu's complicated thoughts, she just seemed very interested in this place, after all, she had only heard of it, but she had never been to a local class.

She was curious about this place, but because it was a forbidden place for the mermaids, comparable to the sacred place where the elven tree of the elves was located, her curiosity was suppressed by her own willpower.

"Yuzu, the elder said that there is a problem with the forbidden land, and also said that you mentioned the old man, what is the problem with this forbidden land? Who is the deceased? Luya stood at the entrance to the forbidden place, not daring to move at all, her body movements were a little stiff, and her voice was much quieter, as if she was afraid of disturbing the rest of the mermaid ancestors buried here.

"I don't know what's wrong with the forbidden land for the time being, but since the five elders have said so, then I definitely want to investigate." Su Yu glanced at the others, and they immediately took the props Su Yu gave them and began to inspect the place for the second time.

Because they didn't think that this could be a fake forbidden place, the last time they checked, they were mainly looking for two things.

One is the exit, and the way into here is actually one-way, and they find that they can't go back the way they came, so they have to go out and have to find another way.

Apparently, they found it.

As for the other thing, it is the pollution that the fish-people put in the forbidden land.

At first, I thought that the forbidden land was real, so it was natural to think that the fish-man put the pollution here, although the result was true, but from the current point of view, the true and false of the forbidden land is unknown, and the fish-man probably didn't know this, so he hid the pollution here.

This can also explain why the five elders did not find pollution after entering the forbidden land, thinking that they did not dare to dig deeper, but the truth is that the forbidden land is indeed unpolluted.

"Lua, remember what I told you about pollution?" Everyone else was here looking for clues, and Su Yu wanted to find it too, but she couldn't leave Lua alone, so she took her to the place where they had found the contamination before.

"Is it this uneven soil?" Luya could clearly tell that the ground in the area that Su Yu had shown her was uneven.

Although it looks like someone has been well restored, it still seems a little abrupt.

"Yes, this is it." Su Yu squatted down and carefully brushed off the top layer of soil, revealing the abnormal black soil below: "These are all dirt that has been soaked in pollution. ”

"Actually, they should all be cleaned up, but we can't take them away." Because Ning Shi said that this pollution has been hidden for too long, and the surrounding environment has been affected more and more.

If all this contaminated soil were to be dug up, it would be time-consuming and labor-intensive, and most importantly, there would be too much of it for them to take away.

Suyu had tried to fit it into her backpack, but this was the first time she had put such a contaminated object in her backpack, but she failed.

When she found that she couldn't put it in, Su Yu was not particularly surprised, because she had already guessed that she couldn't take these things with her, otherwise she would be able to solve all the effects of pollution on the forbidden land by herself, which would be too rebellious.

Therefore, the polluted soil here can only wait for the matter to be over, and let the mermaids clean it up by themselves, Su Yu will ask Ning Shi if he can help them at most, and provide some magic potions by the way, as well as basic purification potions.

“…… It's horrible. Luya didn't suspect Su Yu in the first place, but now she saw so much polluted soil, and her face turned pale suddenly.
