After hugging the tail of the fish

Although the mermaid's brains are full of strange things, the good thing is that they believe what Guiyang says, so it's not a big problem.

This kind of teaching lasted for a few days, until he explained to the mermaid all the various props that humans put in the sea that he knew, and the public class was considered to be over.

"Thank you." Chi Yuan came to pick up Yu Guiyang after class, and brought some easy-to-eat food along the way.

Yu Guiyang was not hypocritical, he just ate Chi Yuan's hand to his heart's content.

He can't wait to share everything he knows with everyone, but unfortunately his energy is limited, and so is the mermaid.

And forcing these mermaids in estrus to attend the class was already very difficult, he couldn't ask for more from them.

Chi Yuan stroked the little mermaid's hair distressedly. These days, all his little mermaid thinks about is giving lessons to the mermaids and helping them identify human creations.

Even after class, he still has to concentrate on preparing for the lesson, dreaming about the content of the lecture.

Chi Yuan stroked the black and blue marks under the little mermaid's eyes with his fingertips: "Take a good rest, and leave the rest to me."

Chi Yuan's voice seemed to have a soothing magic power, and within a moment, Yu Guiyang lay in Chi Yuan's arms and fell asleep.

He asked Gao and Kos to evacuate the mermaid, and immediately brought the tired little mermaid back.

In front of the habitat, Zhang Chang was already waiting there.

Chi Yuan passed him, and Yu Guiyang was laid flat on the soft seagrass bed they built before swimming towards Zhang Chang: "What's the matter?"

Zhang Chang looked at the little mermaid behind Chi Yuan: "Is Xiao Yang asleep?"

"Well, he's too tired and has fallen asleep." Chi Yuan replied, controlling the sound waves.

Zhang Chang sighed: "Wang Wu's betrayal made all the mermaids under Iceland more or less panic. At this time, Xiaoyang's teaching is particularly important. They realize that the mermaid's existence is not so scary if humans know about it."

Chi Yuan hummed, but did not answer. He knew that Zhang Chang still had something to say.

"Master Law Enforcer," Zhang Chang pondered for a long time, "I don't know if I should say something or not."

"Then you don't have to say it." Chi Yuan said.

Zhang Chang frowned in embarrassment: "But I still hope to know your attitude."

Chi Yuan looked at him silently, indicating that he could speak.

Zhang Changdao: "Xiaoyang is very smart, he is the most intelligent mermaid I have ever seen. His appearance is the greatest luck for the former Chiyuan tribe and the current Ocean tribe."

Also mine.

Chi Yuan said in his heart.

Zhang Chang continued: "Obviously he couldn't even speak at first, but in just one month, he was able to master the language of the mermaid."

As if recalling the days when Yu Guiyang taught alone, a smile appeared on Zhang Chang's aged face.

"I...don't dare to ask anything extravagantly from you," he put back his smile. "If in the future, you find that he is different from other mermaids, I hope you can let him go because of his sincerity to you."

Chi Yuan: "..."

He looked at Zhang Chang in disbelief: "Do you think I will hurt him?"

Zhang Chang quickly lowered his head: "I'm just afraid, if one day you stand on the opposite side..."

"There won't be such a day." Chi Yuan said with certainty.

Looking at Chi Yuan's firm expression, Zhang Chang feels at ease.

It's not that he doesn't believe in the relationship between Chi Yuan and Xiao Yang, he's just a little worried.Yu Guiyang's familiarity with humans has far surpassed that of ordinary mermaids.

Didn't Chi Yuan suspect that a mermaid who grew up in the ocean basin knows so many things about human beings?

Chi Yuan glanced at the sleeping little mermaid, his peaceful sleeping face was docile and harmless, which made him feel pity.

"Go back," Chi Yuan whispered, "The things you worry about won't happen, and I will always guard him."

Even if you sacrifice your life, you will not hesitate.

Yu Guiyang slept for a whole day and night.

He stretched, and naturally rubbed against Chi Yuan next to him: "Good morning."

That is to say, the deep sea in the North Pole does not see the sun, and it is impossible to distinguish day from night, making him think it is morning.

Chi Yuan kindly reminded him: "It's time for dinner."

um, dinner?

Yu Guiyang's eyes widened suddenly, all, is it time for dinner?

"I slept all day?" He subconsciously wiped the saliva that didn't exist at the corner of his mouth.

Tsk, this is in the sea, even if there is saliva, it will not stay on his face.

Chi Yuan smiled and kissed Yu Guiyang's forehead: "Are you awake? If you haven't slept enough, continue to sleep, or eat something before going back to sleep?"

"Are you making fun of me?" He looked at Chi Yuan in disbelief.

Is this still his unsmiling mermaid brother?

Of course Chi Yuan would not admit it, he offered the fresh prey he had hunted with both hands in a good temper: "Are you hungry?"

To be honest, he was probably too hungry, and now he doesn't feel very hungry.

But if you should cook, cook, does it have anything to do with whether you are hungry or not?

Of course not, he was just greedy.

So he ate the dinner Chi Yuan had prepared for him, and burped by the way.

"I'm full," he carefully cleaned up the dirt on his hands, "Chi Yuan, take me out for a walk? I've slept all day, I need to exercise my muscles."

Chi Yuan has nothing to do with it: "Okay."

But where should I go?

If it was before, you can go to the shore to see the little polar bear, but now the little polar bear has been adopted by the mother bear.

And with the growth of the ocean tribe, there are already specialized mermaids responsible for hunting and feeding sea fish.

He thought for a moment: "Let's go to Hailing to have a look."

Seeing the mermaids playing cards lively should make him relax a lot.

It's just that he didn't expect that after arriving at Hailing, he didn't see the mermaid playing cards.

"Strange, why didn't you see a single mermaid today?" Yu Guiyang was puzzled.

Chi Yuan said: "Kos asked them to step up their patrols to ensure the safety of the tribe."

Speaking of Kos, Yu Guiyang suddenly thought of something: "Is he okay now?"

"With Gao accompanies, there should be no problem." Chi Yuan said.

Is there really no problem?

Based on his understanding of Coase, this failure will definitely make Coase feel deeply guilty.Although he had comforted Kos at the time, if guilt dissipated so easily, how could there be such a word as regret?

"Let's go find Cos." Yu Guiyang wanted to gossip about Cos and Gao's progress.

Chi Yuan took Yu Guiyang to find Kos. At that time, Kos was leading the members of the fourth team to explore a mid-ocean ridge.

Seeing that Yu Guiyang and Chiyuan were coming, Kos swam over and saluted them.

"Cos, what are you doing here?" Yu Guiyang asked curiously.

Coase replied: "The landform here is a bit special. There are billowing black smoke spewing upwards, and the temperature is also very abnormal."

Yu Guiyang knew it at a glance, this is a characteristic of deep-sea hydrothermal fluids.

Deep-sea hydrothermal fluids are commonly known as "black chimneys", and their formation is inseparable from the movement of continental plates and oceanic plates.

The deep-sea hydrothermal fluid in front of you is the junction of the Eurasian plate and the American plate, and it is also a zone where earthquakes and volcanoes occur frequently.

If he remembers correctly, this piece of deep-sea hydrothermal fluid located on the mid-ocean ridge is the hydrothermal vent area named "Rocky Castle".

Rocky Castle is located in Norway and Greenland, which is the mid-ocean ridge between the Norwegian Sea and the Greenland Sea mentioned earlier.

These spouts of black smoke are actually various metals in the earth's crust, ejected from cracks in the seabed due to a series of complex reactions.

In other words, there are rich mineral deposits here.

But because it is located in the deep sea, and the surrounding temperature is as high as more than 400 degrees, no country has ever exploited it.

Yu Guiyang knew this because the international community has paid more and more attention to the exploitation of seabed hydrothermal fluids. As a marine biologist, he also learned about it by the way.

For humans, these seabed hydrothermal fluids are promising resources for exploitation in the future, but for the mermaids living here, they represent danger.

Because of their existence, mermaids not only have to prevent human detection machines from finding them, but also avoid being scalded by these gushing hot liquids.

"Leave the team, it's not safe here." Yu Guiyang made a decisive decision, "This is a hydrothermal area on the seabed, and the temperature in the shallow layer can reach as high as [-] degrees. If you get burned by the smoke, I'm afraid the mermaid will disappear."

After hearing this, the members of the fourth team retreated one after another, wishing to stay away from the hydrothermal area.

Kos also hurriedly protected Yu Guiyang and Chi Yuan to evacuate.

"I'm sorry." Cos apologized, "I didn't expect this place to be so dangerous. I just want to stay here and let the team members invite you to take a look."

Obviously, he had lingering fears about Wang Wu's escape before.

Yu Guiyang patted him on the shoulder: "Cos, you did a great job. Did you know that there are countless gold and silver treasures here. Although it is dangerous, it is also full of opportunities."

Kos was surprised: "You mean, the kind of gold and silver seen in the sunken ship?"

There is no device for extracting metal in the ocean, and the mermaid's knowledge of gold and silver treasures can only come from sunken ships.

Yu Guiyang nodded amusedly: "It's that kind of shiny metal." By the way, he poured a basin of cold water, "But we don't have mining tools, and the outside of it is too hot, and we'll get burned before we even touch it. .”

Kos sighed regretfully: "So it's useless, right?"

He could see that Kos was so depressed these days, desperate to do something for the Horde.

But in fact, there is no need for it. Coase's excellence is obvious to all.

"Play mahjong with me, it's been a long time." Yu Guiyang smiled, "Call Gao Ao, and give the brothers a holiday."

Kos: "But..."

"Don't be a fool, come on."

"OK then."

Playing cards is a good way to relax. After a round, their expressions are a little more relaxed.

Outside Hailing Cave, there was also the bustling sound of mermaids playing cards on weekdays.

Very lively.

He loves it.

"Kose," Yu Guiyang said while stacking the cards, "Do you know why you fired the cannon just now?"

Kos thought for a while: "Because I made nine articles?"

Yu Guiyang smiled and said: "Of course it's not only because of this reason, but because you always think carefully when you play cards. I just took advantage of your inertial thinking. You think that there is only one left of Jiu Tiao, and no one will play Jiu Tiao. This Then you fell into my trap."

Coase thought about it.

Yu Guiyang continued to explain: "Actually, the types of mahjong tiles are ever-changing. I always think about it, but instead add a gamble to myself. It's better to relax, be more casual, and play as you want."

"Isn't that a loss?" Cos was puzzled.

Yu Guiyang: "Is it important to win or lose? Don't put too much pressure on yourself. Playing poker is just like life. The more important you are to win or lose, the heavier your burden will be. If you can let go of something, you will not It will feel so uncomfortable.”

After all, Kos is the smartest mermaid in the Chiyuan tribe. He immediately understood Yu Guiyang's meaning, and couldn't help smiling bitterly: "Little mermaid, don't comfort me anymore. I understand the truth, but I'm still very sad."

Really stubborn, but this is the Kos he is familiar with.

Steady and calm, with a strong sense of responsibility, but treats himself too harshly.

"Then if I say that Wang Wu won't have a good time with humans, will you feel better?" Yu Guiyang asked.

Kos: "How come?"

"What's wrong with this? Think about it, a mermaid who can't speak, can't continue to be their eyes in the ocean, and has no use value, what will be waiting for him?" Yu Guiyang said cruelly. smile.

For the mermaids who murdered their companions and betrayed their clan, he really couldn't afford even the slightest bit of sympathy.
