After hugging the tail of the fish

To be honest, this is also Yu Guiyang's first human experiment.

Oh no, strictly speaking it is a mermaid body, but because the body structure of a mermaid is similar to that of a human being, he couldn't help but feel a little guilty.

In order to be bold, he specially called Gao and the others to watch together.

Zhicheng and the others were almost frightened to death, and even Kos and Yun Lian were a little terrified of the fruit knife in Guiyang's hand.

As mermaids, they can feel the pain of Zhicheng and the others. The skin of mermaids is relatively hard among marine creatures, and the knives created by humans can easily cut them.

This set off alarm bells for them.

Especially Yun Lian, he was shot by a fish from a fishing boat before, if Yu Guiyang hadn't healed his inflamed arm, he might not be alive today.

After being shot, he once thought that as long as he was vigilant and dodged in time, the possibility of human bullets hitting him would be greatly reduced.

But now he realizes that human beings don't just have bullets, or guns as weapons.Their knives, as well as the torpedoes mentioned by Diya, can easily kill mermaids.

All the mermaids had different thoughts, only Gao, who didn't feel the tense atmosphere at all, opened his mouth and said: "Let you bully me, hehe, the little mermaid will avenge me! Hack him to death!"

He felt that it wasn't enough, so he leaned up to Zhicheng and flicked his tail.

"Zhicheng, Zhicheng, when you beat me up, did you ever think that such a day would come? Hahaha, it's really a reincarnation, who will the heavens spare!"

"I see if you dare to bully other mermaids in the future, little mermaid, scrape off all his flesh, don't save me face!"

"It's best to bleed them again. I didn't bleed a lot back then, let them taste the blood!"

Barbara...

Yu Guiyang couldn't bear it anymore, he clenched the handle of the knife tightly, and the fist peak on the back of his hand was raised, as if he was ready to hit Gao at any moment.

"If you say one more word, I'll cut off your tongue." Yu Guiyang said viciously.

Gao was so frightened that he quickly covered his mouth, and hid behind Kos and Yun Lian in despair.

Weeping and chirping softly: "The little mermaid is so fierce, he actually wants to cut off my tongue! He didn't even think about cutting Zhicheng's tongue, since he screamed so loudly."

Kos rolled his eyes at him, please, Zhicheng was frightened, and it is understandable.

But Gao, the little mermaid didn't kill him with a knife, but he made noise, which seemed to be causing trouble.

Gao should be glad that Chi Yuan went to the shore to hunt food for the polar bear cubs, otherwise, Gao must have been thrown out by now, he bet.

Yu Guiyang was surprised to find that Zhicheng and the others didn't dare to speak anymore, they only looked at the knife in his hand with a cold light in their frightened eyes.

Although Gao was really irritating, his yelling did serve as an example to others.

Forget it, he decides not to pursue Gao's troubles.

But having said that, as far as Gao's brain circuit is concerned, even if he beats Gao up, he doesn't know what he did wrong, right?

I will definitely dare next time.

Without the noise interference, Yu Guiyang's experiment went very smoothly.

He applied Ascophyllum nodosum to every experimental mermaid, but the amount increased or decreased slightly.These Ascophyllum nodosums were carried with them by the mermaids of the Chiyuan tribe, but because there was no nourishment from the soil, this batch of Ascophyllum nodosums was no longer fresh.

But Yu Guiyang believes that although it has been separated from the nourishment of the soil for a long time, the effective hemostatic ingredients it contains should not be lost, so it is very likely that it still has the hemostatic effect.

However, in order to confirm his guess, he asked Gao and the others to collect some fresh Ascophyllum nodosum in the waters of the Bering Strait.

The sea surface of the Bering Strait has been completely frozen. At this time, swimming under the ice surface is not as dangerous as before. It needs the help of sea storms to avoid human detection.

Kos handed the fresh Ascophyllum nodosum to Yu Guiyang, and Yu Guiyang applied the Ascophyllum nodosum on another scar on Zhicheng's arm.

The amount is the same as the amount given the first time, controlling the variables as much as possible.

Of course, there is no weighing thing in the ocean, so Yu Guiyang can only judge whether the amount of medicine applied twice is the same by feeling and vision.

There will definitely be errors, but his original purpose was to explore the optimal application amount and compare the difference in efficacy between fresh Ascophyllum nodosum and stock Ascophyllum nodosum, and there is no need to pursue precision too much.

Today's experiment was over, Yu Guiyang left the cave, nodded to the two mermaids at the entrance of the cave, indicating that they could feed Zhicheng and the others.

Since Zhicheng and the others were in heat in front of the female mermaid last time, although the two female mermaids said afterwards that they had never seen any big storms, Yu Guiyang still didn't want them to suffer this kind of grievance.

Simply ask Yun Lian to find two male mermaids who are not good at hunting.

Mermaids learn to hunt from an early age, and adult mermaids are rarely bad at hunting.But there are always exceptions to everything. One of these two mermaids is born with poor eyesight, and the other is a disabled mermaid with only one arm.

It is worth mentioning that this mermaid with poor eyesight is called Drew, and he only has poor night vision. When the light is sufficient, his vision is not much worse than that of other mermaids.

After listening to Yun Lian's description, Yu Guiyang felt that this symptom was a bit like night blindness.

The emergence of night blindness is mostly caused by the degeneration of rod cells, which causes the retina to gradually lose vision in dim light.

The reason why mermaids have such strong night vision is precisely because the rod cells on their retinas are highly active, allowing them to see their surroundings clearly in the dark.

Yu Guiyang asked Yun Lian about Drew's situation, and had a certain judgment on Drew's illness.

He learned from Yun Lian that Drew has been unable to see in the dark since he was a child, so Drew should be suffering from congenital night blindness.

In human pathology, congenital night blindness has not found an effective treatment so far. It can only be relieved by dilating blood vessels or supplementing vitamins A, B1, and B12, but none of them can solve the problem of being unable to see in dark light.

However, mermaids and humans are two different species. Perhaps mermaids' night blindness is not invincible?

Yu Guiyang felt that he could try to make a meal plan for Drew first to see if the diet therapy was effective.

So he asked Yun Lian to give the boy with one arm a normal meal, but what he gave Drew was a therapeutic meal selected by Yu Guiyang.

At first, Drew had objections.

After all, the food for him had a lot of fish livers and kidneys, as well as meat, but it was much less than that of the other mermaid.

He also thought that Yun Lian was treating them differently, so he deliberately found Yun Lian's theory.

But Yun Lian told him that his food was carefully selected by Yu Guiyang and it was good for his body.

He no longer complained about his bad food.

Some mermaids saw him eating fish liver and kidneys, and thought that he had bad eyesight and could not catch prey, so they wanted to give him some of the meat they hunted.

But he rejected them one by one.

Facing the doubts of the mermaids, he proudly puffed up his chest: "You don't know, Master Yu Guiyang picked these foods for me!"

Immediately, the mermaids cast envious glances at him.

Yu Guiyang has never heard of these things. How could he know that because of Drew's incident, taking care of the experimental subjects has become a job that everyone is vying for.

They all want Yu Guiyang to help them choose food, treat illnesses, and strengthen their bodies without illnesses!

Besides, it is their honor to be able to do things for the little mermaid!

It's a pity that they are in good health and are not qualified to compete with these two mermaids for the spot.

The temperament of the male mermaid is naturally not as gentle as that of the female mermaid, but it is just right to take care of Zhicheng and the others, forgive them and they will not be in heat with the male mermaid.

After the two male mermaids finished feeding, Yu Guiyang left Drew alone and asked him about his recent situation.

In front of Yu Guiyang, Drew seemed a little cautious: "Master Yu Guiyang, after eating the food you prepared for me, I feel much better in health, and I have endless energy every day."

Yu Guiyang raised his forehead, brother, your flattery is too obvious, I don't accept it!

He originally thought that Drew would have an opinion. After all, fish liver and fish kidneys not only taste much worse than meat, but also have an unpleasant fishy smell.

But not only did Drew have no objection, on the contrary he praised him too much.

This is what worries him even more. If the patient cannot tell his physical condition well, he will not be able to determine the effect of the diet therapy, and there will be no way to improve it.

After all, he is also a doctor with a half bucket of water, and many things have to be moved forward by touch.

"Drew," Yu Guiyang said seriously, "I want to cure your night blindness, but this requires your cooperation."

"Night blindness?" Drew repeated Yu Guiyang's voice in a daze.

Mermaids don't have the term "night blindness". Yu Guiyang still uses the word-making method of Chinese characters, combining the three sound waves of "night", "invisible" and "disease".

Yu Guiyang explained: "Night blindness is the disease you are suffering from now. It will make you unable to see clearly in low light conditions. I want to cure you as soon as possible, so as not to waste this rare estrus period."

Winter in the Arctic is polar night all day long.

For Drew, this is tantamount to a long torture.During this period of time, the other mermaids gained precious breeding time, while all that was left to him was darkness day after day.

"It turns out that I am a disease. I thought it was born, just like Wang Liang." Drew suddenly said.

Wang Liang was the mermaid who lost an arm. It was a real disability. Yu Guiyang had no choice but to see if there was a chance to install a prosthetic for him in the future.

Yu Guiyang said to him: "I must first tell you that there is no precedent for successful cure of this disease. I can only try to treat it, but I cannot guarantee success."

Drew, on the other hand, has no doubts about Guiyang's medical skills, or everything about him.

His eyes were eager, with infinite longing in his eyes: "Master Yu Guiyang, please don't be humble, no matter what the result is, I can accept it with joy. I just feel panic. I didn't expect you to be willing to waste your precious money for me." time. Not only picking out food for me, but asking me about myself.”

As Drew spoke, his eyes turned red.

He has never experienced such warmth. He was not taken seriously since he was a child, because his brother and sister are healthy mermaids. Only he can't see when he is in the deep sea. Even in the shallow sea, he can't see at night.

Because of this "night blindness", he was often bullied and ridiculed when he was a child.

Even his parents regarded him as a disgrace to the family.

Later, when I grew up a little bit and left the family and entered the big family of the ethnic group, the situation improved a bit.

The mermaid only eats breakfast and dinner, while he only eats breakfast and lunch, and every time he hunts, he gets a shallow sea area, where he has to avoid human fishing boats and find suitable prey.

At that time, he was still half a boy, and without the help of his parents, siblings, he couldn't even eat enough.

On the other hand, the brother who usually plays well will give him some food from time to time, saying that he can't eat it, but he is very clear about the reason.

Drew, who also wanted to do something for his companions, no longer acted alone, but followed his companions every day, hunting in the deep sea.

He cannot see with his eyes, but he hears with his ears and smells with his nose.

Although he is often scarred, his physical fitness and fighting skills have made a qualitative leap.

Later, his parents and siblings no longer think he is a useless mermaid.

But he didn't need them anymore, he had companions, he had the big family of the tribe, he didn't need anything.

In fact, he didn't plan to come this time, because he heard from the elder mermaid that the winter in the North Pole is dark, and it is even darker under Iceland.

But Zhang Chang wanted him to come, so he had to obey the arrangement of this elder who was also a teacher and father. After all, Zhang Chang helped him a lot during his growth.

Go and go, as if you were sleeping in the past, anyway, you can't see anything, and when you see something, the estrus period will pass.

He has always thought so.

Until today, at this moment, Mr. Yu Guiyang told him that he was just sick.

Yu Guiyang patted Drew on the shoulder, he could somewhat understand Drew's mood.

Disability is more deadly to mermaids than humans. In a human society with a sound welfare mechanism, disabled people can apply for a disability certificate and enjoy state subsidies.You can also shine in some aspects with your unyielding will.

Mermaids are different.

Disabled mermaids are more difficult to hunt prey than healthy mermaids, and it is also more difficult to survive in the ocean. Survival of the fittest is vividly reflected in them.

The Chiyuan tribe is not bad. He heard Zhang Chang tell him that once there are disabled mermaids in some tribes, they will be abandoned when they are still cubs and let them fend for themselves.What's more, these cubs will be eaten as prey.

Yu Guiyang had no way to stand on the moral high ground and criticize these mermaids, because he didn't think he was qualified to do so.It is not easy to survive in the sea, if he had not encountered the abyss, if the place he crossed at the beginning was full of ferocious sea beasts, then he would not have survived till now.

"Don't call me Mr. Yu Guiyang, call me by my name, Drew." Yu Guiyang said warmly, "Don't think that I'm wasting time, I'm doing something that I think is meaningful, then it's not called waste time."

Drew lowered his head: "I'm sorry, Master Yu Guiyang."

"Ok?"

"Yu...Yu Guiyang." Drew cautiously called out Yu Guiyang's name, "I, can I really call you that?"

Yu Guiyang shook his head and laughed: "Of course, I am your companion. Your law enforcement officer is Chi Yuan, and he is your lord."

Drew said: "But Zhang Chang said that from now on, you will be the king of our tribe."

Yu Guiyang: "..."

Hey, I almost forgot about this, he is planning to unite the Chiyuan tribe and the Diya tribe, but this matter has not been written yet.

The teacher is too impatient, so he started to create momentum for him?

Unavoidably disappointing Zhang Chang’s painstaking efforts, Yu Guiyang pondered for a moment, and said to Drew, “Call me by my name in private, I’m not used to people calling me Sir when I’m chatting privately.”

Drew nodded vigorously: "Thank you for your gift."

Yu Guiyang: "..." Wait, this tone of voice...

By the way, did Drew just say that Zhang Chang announced that he would become the king of the Chiyuan tribe?

The title Wang must have come from Diya's mouth, absolutely!

"Let's get down to business," he decided not to dwell on this issue, "After eating fish liver and kidney, has your eyesight improved a bit? To be honest, don't be like that just now." Flattering.

Drew had no choice but to tell the truth: "No, I still can't see anything."

This is entirely within Guiyang's expectations. If congenital night blindness is so easy to treat, there won't be no effective treatment options so far.

"Eat according to the healing meal I prepared for you. The treatment of night blindness is a long process, and it may even be impossible to cure it with hard work. But at least we have tried our best to treat it, are you right?" Yu Guiyang said as a German Lu's attending doctor must give Drew enough confidence.

How did he know that Drew's confidence in him was not only sufficient, it was simply overwhelming.

To him the deep sea is darkness, the night is darkness, the Arctic is darkness, and Iceland is darkness.

Only Yu Guiyang in front of him was a light shining into his dark world.No one has ever told him that this is a disease, they will only ridicule, ridicule, and even stay away.

Only Yu Guiyang is willing to help him overcome the disease, and only Yu Guiyang has the ability.

After seeing Drew off, Yu Guiyang waited for a while but did not find Chi Yuan, so he decided to go to Diya's tribe by himself.

It was only when he was talking to Drew that he thought of Diya, and remembered that they hadn't negotiated a good cooperation yet.

He carried the backpack with the necklace on his back. After all, he was a partner. He felt that it was necessary to give Diya a necklace.

Besides, Diya is the leader of the Diya tribe, and her own image is also very good. She is wearing this necklace, which is like a mobile advertisement!

"Kos, Yunlian, I'm going to the Diya tribe." Yu Guiyang said to the two mermaids.

Kos hesitated: "Aren't you going to wait for Chi Yuan to come back?"

Yu Guiyang waved his hand: "No, the habitat Diya chose is very close to the sea ridge, and we will arrive soon."

After they confirmed their cooperation, Diya moved her habitat near Hailing to facilitate contact with Yu Guiyang and the Chiyuan tribe at any time.

"If you haven't returned after Chi Yuan came back, and he asked about your whereabouts, how should we answer?" Yun Lian was still cautious, and even asked this question.

Yu Guiyang scratched his head, Yun Lian asked this question well and managed to stump him.

If Chi Yuan knew that he went to see Diya secretly, he would be angry, right?

Or don't worry about going, wait until Chi Yuan comes back, Chi Yuan has gone to feed the little white dumpling, and he shouldn't be back in a long time.

However, Gao asked at this moment: "Little mermaid, you are not afraid of Chi Yuan, are you?"

Kos glanced at him, slightly reproachful.

It goes without saying, is there anyone who is not afraid of Chi Yuan?

Yun Lian looked at his nose, nose and heart, pretending not to hear this sentence.

Yu Guiyang raised his chin: "Who is afraid of him?" It just sounded a little lacking in confidence.

The most powerful thing about Gao is that he didn't mean any sarcasm at all, but he was able to ask questions that made people angry: "Then what are you dawdling about? You just go, and when Chi Yuan comes back, we will say that you were killed by old man Zhang." Call him away, he won't know you went to Diyana, don't worry."

It's a matter of face, Yu Guiyang refused to budge: "There's nothing to be afraid of, just tell the truth, Chi Yuan knows that we have cooperation with the Diya tribe, he won't be angry."

Gao tilted his head: "Did I say that he would be angry? Why was he angry? Could it be because you went to find Diya and didn't take him? What did he want to do with Diya? Could it be that he finally figured it out and wanted to talk to Diya?" Are you together?"

Yu Guiyang: "..."

He silently took out a fruit knife from his backpack.

Gao was so frightened that he quickly covered his mouth, shook his head desperately, and signaled Yu Guiyang not to speak anymore.

After Yu Guiyang left angrily, Kos turned his head to look at Gao, and said expressionlessly, "You are dead."

"Ah? Why?" Gao still didn't feel that he had done something wrong, "I just asked too many questions and talked too much. Do I deserve to die if I talk too much?"

The corner of Kos' mouth twitched. Surprisingly, he answered him patiently this time: "I remember I told you that Chi Yuan likes Yu Guiyang."

Gao nodded: "I remember too."

"Then why do you still say that Chi Yuan is finally going to be with Diya?" Kos put his hands on his chest, "You run away with the little mermaid anger, and when Chi Yuan comes back, you will be finished."

Gao's eyes widened, and he didn't dare to say anything: "I just said that Chi Yuan is going to be with Diya, why did the little mermaid run away in anger?"

Kos: "..."

Yun Lian couldn't stand it anymore, and sighed, "Can't you see that the little mermaid also likes Chi Yuan."

Gao froze.

"It's my fault," Cos raised his forehead, "I thought that only mermaids with eyes could see this situation, but I didn't expect Gao to be blinder than Drew!"

Drew didn't know when he popped up out of nowhere: "I'm not blind, Mr. Yu Guiyang said, I'm night blind, don't call me blind again."

Gao kicked Drew on the ass: "Is this the time to talk about this? Kos, Yun Lian, you need to save me!"

Yun Lian shrugged: "It's hopeless, so please be blessed."

Gao had no choice but to look to Kos for help.

Kos pondered for a long time: "Just as you said, tell Chi Yuan that Zhang Chang called him away, and maybe there is still a glimmer of life."

Gao hurriedly asked, "What is the silver lining?"

Cos: "Before Chi Yuan goes to Zhang Chang to confirm, the little mermaid can return to Hailing and fulfill your lie."

Gao was trembling with fright, and he kept reciting the words Cos taught him: "Old Zhang called the little mermaid away, old Zhang called the little mermaid away..."

When he was restless, Chi Yuan came back.

Sure enough, the first sentence was to ask Coase and the others: "Where's the little mermaid?"

Cosburn was going to answer for the fool.

Unexpectedly, Gao himself said: "Zhang Chang captured the little murloc!"

Chi Yuan: "Huh?"

"No, no," Gao became even more nervous after saying the wrong word for the first time, "The little mermaid took old man Zhang away!"

Chi Yuan looked down at him, the overwhelming aura swept over him, Gao Ao was already guilty, and now he was sweating profusely: "Is it Zhang Chang? No, is it Diya? Or the little mermaid?"

He was completely bewildered.

Chi Yuan keenly caught a name in Gao's mouth: "Has Diya been here?"

"No, no, Diya didn't come! No Diya!" Gao was so nervous that he couldn't speak clearly, his brain crashed, so he had to start from the beginning, "I, Kos asked me to say, no, he didn't let me say... ..."

"What!" Chi Yuan said angrily.

Gao: "He didn't let me say that the little mermaid went to find Diya, he wanted me to tell you that Zhang Chang called him away, I said the little mermaid was afraid of you, but the little mermaid said he was not afraid of you, he told us to tell the truth ..."

Kos: "..."

Oh, the idiot.
