Let you teach, you play games with the worst class?

They always feel that their teachers are scaring them, but they also feel that this may happen...

In the ocean, are there still few strange-looking creatures?

But in this way, I still can't dive...

When everyone's expressions were tangled, Qingdong, the best swimmer in the ninth class, plunged into the sea with a fierce son.

No matter what others are like, anyway, he wants to go to the sea to have a look.

And just now they snorkeled and saw that there are no large creatures in the sea, so they don't know what their classmates are afraid of.

Under the suspicious eyes of everyone in class nine, Qingdong had already dived about five meters.

Just like what my teacher said, deep diving is not difficult.

It even feels easier than snorkeling.

Emergence also needs to consider the situation that the breathing tube accidentally enters the water or completely enters the sea and cannot breathe.

But Deep Dive didn't take this into account at all.

The connection between the breathing tube and the mask is perfect. As long as you don't take off the mask, there is basically no water ingress, and the oxygen is completely sufficient.

Except that there is not enough light here, there is no essential difference from the land.

As for the sense of claustrophobia and fear that the teacher mentioned earlier?

Qingdong didn't feel it at all, rather, what he felt at this moment was the real harmony of milk and water.

When I saw colorful unknown fish swimming past me.

Qingdong felt an indescribable joy in his heart.

Time passed slowly, and everyone in Class [-] was snorkeling to watch Qingdong's movements.

Only Ren Yanhuo sneaked down together with Qingdong, and fell not far away to protect secretly.

Even if this sea area is not dangerous, Ren Yan is still more worried about accidents.

Qingdong's speed was very fast, even faster than his own speed just now.

It only took about six or seven minutes, and he was close to the bottom.

The moment he approached the bottom, he controlled his figure to turn upside down and stood firmly on the bottom of the sea.

Soft and dense.

Just like the touch of that small island.

"It seems that Mr. Ren's guess is somewhat reasonable..."

Qingdong thought about it secretly.

The figure began to swim around non-stop.

He also remembered why they learned to dive deep.

After a while, Qingdong's figure stagnated.

Tong Kong unconsciously zoomed in a bit.

In front of his eyes, a broken ship was covered with mud and sand.

There are a few strands of debris floating around, and some fish and shrimp corpses.

On top of the ship, a huge coral together with incomplete wood and sand formed a small platform.

On the upper end of the platform, there is an obvious fracture mark...

"Well, is there anything down there?"

On the surface of the sea, the moment Qing Dong just surfaced, a group of Class [-] students couldn't wait to surround him and ask questions in a hurry.

Qingdong took a few breaths and nodded affirmatively: "Yes, a spectacle!"

"What a spectacle, a shipwreck?!"

Everyone in Class Nine continued to ask, and they were far more concerned about this guess than Deep Dive.

Qingdong didn't bother to make any jokes, so he directly told what he had seen and heard:

"Yes, and it's not just the shipwreck."

"I also saw the coral that Mr. Ren guessed before."

"It is indeed huge, although it is not as exaggerated as 12 meters."

"But there is still a height of seven or eight meters, and the width is not low, and the bottom is enough to form a small platform."

"The boards and soil of the sunken ship above are completely intertwined with the coral, and there are obvious fracture marks on the upper layer. I think that fracture is the deserted island we see now."

Panting heavily, Qingdong spoke out what he had seen.

It made everyone in class nine and netizens excited.

Shipwrecks often represent a dusty history and an adventure that belongs exclusively to the ocean.

This unusually rare situation made the entire Class Nine jump with joy.

I felt that the cowardice that was frightened by Ren Yan's few words just now had some courage.

But just as this passionate emotion continued to brew, Class Nine still had a few calm guys.

Xia Yue was on the deck of Class No. [-], looking down, with a hint of puzzlement in her tone:

"The sea here looks quite clear, although I didn't snorkel just now to look down."

"But if the coral is really that big, other people should be able to see it at a distance of more than 50 meters."

"Why do you all act as if you didn't find out?"

"It's different." Hearing this, Qingdong shook his head: "The sea here looks really clear, but after about 30 meters, the light starts to be obviously insufficient."

"Although there is still some visible range, this range will immediately drop to about five meters."

"When I actually reached the bottom, the visible range was only about two meters."

"If I hadn't been searching for a long time on the bottom of the sea, I might not have been able to see the sunken ship and coral, let alone you on the sea."

"And our island, I also took a look when I came up."

"It is completely made of wood, soil and coral. The length of the break is not very high, only about one meter."

"It's normal to not be able to see clearly at sea."

"Of course, there is one more important thing. The temperature on the bottom of the sea is actually higher than that on the sea surface. Especially near the sunken ship, the temperature has risen significantly."

Speaking of this, Wang Yu's eyes suddenly lit up, and his frown suddenly loosened:

"Then it all makes sense!"

"What makes sense?"

When everyone heard the words, they immediately turned their curious eyes over.

"Why did the coral break, and why did this island float up!"

"Don't you find it strange?"

"Coral is hard and grows on the bottom of the sea. It is more difficult to get this thing to break through the water than to go to the sky."

"And a ground formed in the sea, how could it float up for no reason?"

"It's all irrational everywhere."

"But it makes sense if there's a significant temperature rise on the ocean floor!"

"I've been wondering about this just now."

"Now everything is solved, because there is a small active volcano deep in this seabed!"

"And it should have erupted not long ago, and the specific location is probably under the sunken ship."

"It's definitely not very powerful, otherwise the sunken ship would have been smashed into slag long ago."

"But it should have a certain pattern, and it should be able to persevere in transmitting its strength upwards, thus shattering that big piece of coral."

"And in this way, the growth of this coral also makes sense!"

"Because things like coral polyps naturally like a warm environment, a small active crater on the seabed can just provide them with a suitable temperature!"

Speaking of this, Wang Yu's eyes became more and more bright, and he felt that he had discovered something extraordinary.

But everyone in Class Nine understood it instantly, and their eyes also began to shine.

Hearing Wang Yu's words, seeing his teacher's smiling and silent expression, and the fact that there was no Qingdong in the matter of going back and forth.

One thing is certain in their hearts.

What kind of volcano is on this seabed!

So it's just a hot spring that erupts occasionally, okay? !

Thinking of this, the hearts of everyone in class nine immediately floated.

I am going to take a deep dive immediately after Qingdong~

Soaking in hot springs in the sea in the winter, just thinking about it makes me feel comfortable!

What shipwreck, is it important to have hot springs? !

However, it hasn't waited for them to do some psychological construction.

The two figures were pierced down with one fierce son, leaving only two sprays...

Sun Hao and Niu Pu stepped into the ocean.

Adopt the method of treading water in the opposite direction and approach towards the bottom of the sea immediately.

The purpose of the two of them rushing here is simple.

Sun Hao felt that it was a pity that he couldn't take a look at such a fantastic scene and make up a story for himself!

Niu Pu thought that some interesting history might be unearthed from such a strange shipwreck.

It's frustrating if you can't participate in it yourself.

As the only two people in Class Nine who were not interested in hot springs, they actually found a different sense of "comrade" during the deep dive.

In the back, Ren Yan shook her head, and quietly fell behind the two of them again.

Ren Yan felt that she was careless...

Teaching the whole class nine to play deep diving by myself is really a test of physical strength...

.......

On the sea level, watching the third surging wave, Qingdong touched his neck, and said hesitantly:

"I forgot to mention one thing just now..."

"It's true that the temperature is high near the sunken ship, but there are still many dead fish and shrimp..."

"Maybe, also..., a little dangerous?"

As soon as this remark came out, the corners of the mouths of the people who were still on the sea level couldn't help but twitch, and they offered a little bit of sympathy for the three teachers and students of Ren Yan in their hearts.

For an active volcano that can kill small fish and shrimp, the temperature of the eruption must be at least fifty or sixty degrees...

Although it will not pose any threat to humans, it is enough for the three of them to drink a pot.

Even if the probability of another eruption is very small...

After Qingdong finished speaking, Wang Yu also clapped his hands:

"Hey, that's right!"

"Since the visibility on the bottom of the sea is not high, why don't we bring a flashlight down?"

"I remember there were some waterproof flashlights on board."

talk off...
