Let's put it this way, there is a lot of pollution in his body, so much so that Ning Shi has treated so many mermaids, the pollution on his body is not as much as he alone.

But with so much pollution on the Great Elder's body, his shark beads were still clean.

This test result made Ning Shi couldn't help but wonder if there was something wrong with her magic, so she waited for the transfer to check it again, and the result was the same as before - the Great Elder's body had a lot of pollution, but his shark beads were very clean and not affected in the slightest.

Otherwise, with this level of pollution, he would not have enough ten lives to die.

"That's not right......" Ning Shi was very puzzled by the results of his examination.

Although she hadn't treated too many polluted creatures herself, she had never eaten pork and had seen pigs run, and there was a good senior light magician in the church who would often teach them by the way when healing, so Ning Shi didn't know a lot about this 'case'.

But this is the first time I've seen the Great Elder in this situation!

The hard work paid off, Ning Shi spent a lot of magic to study the Great Elder's shark beads, and finally found the reason why his shark beads were not polluted - the Great Elder's shark beads were wrapped in a thin layer of unknown energy.

It was this energy that kept the pollution out, so that the pollution did not seep into the shark beads and saved the life of the Great Elder.

The level of this energy was very high, at least much higher than Ning Shi, otherwise she wouldn't have worked so hard to find out, but it was precisely because of its high level that it had the ability to block pollution.

"This energy ...... It's not like this Great Elder. Ning Shi thoughtfully withdrew his light element, and then took a moment to slowly purify the pollution on the Great Elder's body.

Because there was too much pollution, Yi Ningshi's current strength could not be completely purified, so she could only reduce the pollution on his body first, at least this would reduce the burden on his body, and it would also make the Great Elder wake up.

When you wake up, the purification will be easier.

About half an hour later, Ning Shi left the room, and then met the four elders at the door who had been waiting for an unknown amount of time.

"May I ask how the Great Elder is doing now." The four elders saw Ning Shi come out, and they couldn't wait to ask the eldest elder about the situation.

Ning Shi thought about it, and except for not saying the unknown energy, everything else basically answered truthfully.

Although the four elders already knew that the shark bead would be polluted, Ning Shi spoke very skillfully, she only said that the great elder had a relatively serious pollution in his body, and never mentioned the situation of the shark bead, and then emphasized that the pollution had been purified a lot, and the four elders naturally did not have the heart to think about the shark bead.

"Thank you so much, Magician! If it weren't for you, our mermaid clan would definitely have died a lot of merfolk because of pollution......" If it weren't for the gender, the four elders would have wanted to rush over directly and grab Ning Shi's hand, and thank him fiercely.

"When the Great Elder wakes up, I will tell the Great Elder everything, we merfolk have always been gracious, and when this matter is over, the merfolk will definitely give a heavy gift!" The four elders also wanted to send some things out now, but he had a lot of things on him, but they were all for combat, and none of them could be used as gifts.

And he is not in charge of managing the mermaid treasure house, and there is no way to go to the treasure house to get things right now, so he can only thank him verbally first, and then make an 'IOU' very embarrassed.

"Well, let's talk about it when it's over." Ning Shi is not a virgin who does not eat the fireworks of the world, she will not be greedy to ask for too much reward, but she will definitely take all the part she deserves, and polite resignation is not a thing.

However, there is something about this unknown powerful force, and Ning Shi still wants to inquire a little.

"Fourth Elder, I have a few questions for you, if you feel offended, please don't mind." Ning Shi actually only had one question she wanted to ask, but she was afraid that asking this question directly would cause the four elders to find out, so she decided to ask a few more.

Personally, she felt that the questions she was going to ask later were not secrets, but in order not to make the four elders think too much, she gave the four elders a preventive injection first.

The fourth elder paused and spoke generously: "You are the benefactor of the mermaid clan, if you have any questions, just ask, as long as you can answer them, I will definitely answer them." ”

"And don't say anything you don't mind, I won't say anything that can't be answered."

With the words of the four elders, Ning Shi spoke with confidence.

"What was the room where the Great Elder rested just now used to do it?" Although it is only a matter of making up the numbers, Ning Shi will definitely not just ask some unnecessary trivial things.

If we can find an answer to this question, we may be able to find the reason why the pollution is so strong.

"This room was originally a house where other merfolk lived, but now this place is too close to the protective shield because of the danger outside, so I let everyone move inside." When the merfolk moved in, the outside room was vacated, and it was used as a resting place for the merfolk warriors.

Ning Shi was a little regretful, she also hoped to find something, but it turned out that this house was just an ordinary house, and it was obvious that the cause of the pollution could not be found in this house without any characteristics.

Although he understood it in his heart, Ning Shi still reminded him: "The pollution of that house just now appeared inexplicably, you can ask the original owner of this house if anything strange has happened recently." ”

The four elders said they knew: "Do you have any other questions?" ”

Ning Shi nodded, continued to ask a few questions that were not light or serious, and then when the four elders had already relaxed, he pretended to be unintentional and asked casually, "The Great Elder should be the most powerful mermaid of the mermaid clan, right?" ”

Maybe it was because Ning Shi's previous question made the four elders relax their vigilance, and there was actually nothing special about this question, so he didn't think much about it, and gave the answer directly.

"The Great Elder is indeed the most powerful mermaid of our mermaid clan......" Halfway through his words, the four elders seemed to remember something, and their faces became a little strange.

Ning Shi knew that there might be clues at a glance, so he continued to ask: "With the current situation of the Great Elder, he can't wake up for the time being, and the combat power of the mermaid clan has greatly decreased......"

Although the fourth elder was very reluctant to admit it, he knew that what Ning Shi said was right.

He shook his head and sighed, and subconsciously said, "It would be nice if that person was still there......"

Ning Shi's eyes lit up, but she still tried to make her emotions seem less excited and urgent.
