Chinese students at Hogwarts

The lake water is freezing cold, and Zhang Xiao has not used the Head Soaking Curse yet, because through the Head Soaking Curse, his observation of the outside world is actually somewhat distorted.

He felt the rapid loss of heat and secretly clicked his tongue. At this moment, he heard several other dull sounds.

It was Harry and the others who also came down. Zhang Xiao made a few simple gestures to them to let them get used to it first.

The water temperature under the ice is basically fixed at 4 degrees Celsius, which is very low. The situation that froze Jack to death when the Titanic sank is almost the same as it is now.

Sure enough, there was a problem with this adaptation. Zhang Xiao found that Xiao Ma's body was twitching slightly, and his hands and feet were as stiff as two logs.

As a last resort, they immediately returned to the lake and got into the warm tent with a fire pit. Zhang Xiao waved his wand to dry Malfoy's clothes.

Hermione handed over a blanket and a cup of hot cocoa. The little witch's face was pale and not very pretty.

Malfoy thanked him shakily and took a big gulp of hot cocoa, feeling a little better.

"What happened?" Harry and Ron were confused. Although they felt uncomfortable when they first entered the water, they didn't have such a big reaction.

I had just entered the water, but I saw Zhang Xiao constantly gesturing to float up.

Cedric dried the clothes of the other little wizards and took out a few stalls, but he understood Malfoy quite a bit.

"Draco has no experience diving in this kind of water before, so he is not used to it."

Malfoy nodded and said with some fear:

"Well, after I went down, I just felt my heartbeat was pounding, there was a constant ringing in my ears, my hands and feet were numb, I couldn't breathe, and I couldn't move anything."

"Cold shock -" Zhang Xiao said with certainty. This was knowledge he had learned when he was diving in his previous life, but like most people, he only had a taste of what he did in his previous life and just tried it.

Seeing that the little wizards were still a little confused, Zhang Xiao could only explain further:

“Prolonged immersion or just entering cold water may cause cold shock, which may be manifested by the inability to control breathing or hyperventilation.

Dizziness, tinnitus, numbness of hands and feet, and loss of consciousness occur.”

The little wizards were frightened when they heard this. These were the fruits of research by Muggles. Zhang Xiao originally thought that wizards' instinct to distort damage would allow them to avoid this risk.

But it seems that they will not instinctively try to avoid the impact of this environment as they would directly face the harm.

Neville listened silently. He was the person in the best physical condition except Zhang Xiao. Taoism paid more attention to physical exercise than wizards, and generally had an advantage in this situation.

But he couldn't help but said:

"So even if this doesn't happen at the beginning, it will still happen after a long soaking time?"

Zhang Xiao nodded.

"So we have to think of something and I don't think the second round will be over in an hour or any time."

Hermione got to the point.

In fact, there are still many problems, such as diving sickness, which Zhang Xiao did not mention. Wizards have good recovery methods in this area, and they are only afraid of a few special things.

The atmosphere in the tent became silent. No one expected that the problem before them would be so difficult.

Just entering the water at the first level stumped them, and they knew from the previous discussion that the ruins were likely to be a hundred meters or more underwater.

"Let's leave this question until later -" Zhang Xiao stood up and said affirmatively:

"Even if we find a way to reach the ruins safely, we still have to enter the water in the end, so it is necessary to adapt to the underwater environment in advance."

Ron pointed at Malfoy and shrugged:

"But he's already like this -"

The rest of the words were not said, but everyone understood that Malfoy suddenly lifted up the blanket on his body.

It’s okay to be ridiculed by anyone, except Weasley!

"I can!"

"Don't make any noise, like this." Zhang Xiao just thought for a moment, raised his hand and snapped his fingers:

"Uncle Yun."

There was a slight explosion, and the elf appeared in front of everyone, respectfully:

"Master?"

Zhang Xiaoling, who is the executive vice president of Slytherin, took out paper and a brush and wrote a note.

"Give this to Professor Snape."

The content of the note was very simple, asking the dean to give Draco a gillweed so that Draco could adapt to the underwater environment.

If I remember correctly, this kind of grass can help the user evolve gills and webs, and can further adjust the body's adaptability to water temperature, similar to fish.

Yun Bo came back very quickly. The herb is a rare medicinal material, but it is nothing to Snape. The range of use of the herb is very small, but it is difficult to find.

So after seeing Zhang Xiao's request, he gave it without hesitation.

A group of young wizards came to the entrance of the ice cave again. Malfoy suppressed his nausea and stuffed the gill grass into his mouth.

"Ugh - it tastes terrible. It tastes weird, tough and greasy, like the tentacles of an octopus."

Malfoy swallowed the gill grass with difficulty, and the little wizards also swallowed because they watched a lump in Malfoy's throat slowly slide down.

Everyone shivered in the cold wind, waiting for Malfoy to change.

At this moment, Malfoy suddenly felt as if an invisible pillow was pressing down on his mouth and nose.

As soon as he took a breath, he felt like his mind was spinning. His lungs were empty, and there was a sudden sharp pain like a knife on both sides of his neck——

He couldn't help but grab his throat with his hands.

Malfoy's strange movements attracted everyone. They saw two narrow slits under Malfoy's ears, opening and closing in the cold air... He had gills!

“It really works!”

Zhang Xiao kicked Malfoy on the butt, which looked like a fish jumping on the shore.

'Plop!' The water splashed loudly, but soon Malfoy leapt out of the water, jumped upright in the air with a very graceful gesture, and drilled straight through the hole.

It looks like it’s done!

Then everyone jumped into the hole one after another.

The underwater world has a kind of tranquility. In this environment, every sound in the body is amplified.

Malfoy was like a swimming fish, moving flexibly around everyone.

This feeling is so wonderful, breathing in the cold lake water is like getting the oxygen needed for life.

His head was no longer spinning; on the contrary, he was as clear-headed as ever.

Malfoy took another deep breath of water, feeling the water flowing smoothly through his gills and delivering oxygen to his brain.

He stretched out his hands in front of him and looked at them carefully.

They look green and scary underwater, and their fingers are connected by webs. He turned his head and looked at his bare feet—the feet had become longer, and there were webs connecting the toes, as if his feet had suddenly turned into duck webs.

The water was no longer freezing cold... On the contrary, he felt very cool and comfortable, and his body became very light...

The webbing on both hands and feet is so easy to use, it can fly very far with just a slight slide.

Compared to Malfoy, who looked like a fish, the other little wizards looked particularly stiff.

Harry looked at Malfoy with envy as he shuttled back and forth around, wondering if he might as well eat gillweed by then.

However, the effectiveness of this product is limited. One pill seems not enough. Neville also said that it has side effects. If you eat too much in a short period of time, it will become irreversible.

It would be great if I could use animagus to transform into a fish.

They followed Zhang Xiao and swam slowly towards the bottom of the lake. This time there was no goal, it was more like a simple outing at the bottom of the lake.

What you have to do is to stay in the water as long as possible and go as deep as possible.

See if there are any problems and note them down for resolution.

Therefore, everyone can take a good look at the scenery at the bottom of the lake in a more relaxed way.

The light penetrates in a soft and mysterious way, illuminating this deep world.

The sunlight shines through the sparkling water, forming beams of light, like searchlights in nature, bringing a touch of life to the dark bottom of the lake.

A broken boot lay quietly under the water. It seemed that it had been lying there for a long time.

It was covered with a thick layer of something like dust, and some small fish considered it their home, wandering around and constantly moving in and out of the shoe tubes.

The little wizards swam deeper and deeper, and Zhang Xiao felt only silence in his ears.

Without opening his Dharma Eyes, he could only see the scene within a ten-foot radius, so every time he paddled in the water, a new scenery suddenly emerged from the darkness in front: undulating, tangled black water plants. jungle, wide flat stretches of sand scattered with shiny pebbles.

This is much more interesting than snorkeling and scuba diving in my previous life, but I still have to experiment.

Zhang Xiao focused his attention on his eyes, which suddenly became bright and lively, and the entire bottom of the lake seemed to be clear and vivid under his eyes.

It was like the entire bottom of the lake suddenly lit up. Underfoot, the thick mud was soft and slippery, and every step was accompanied by a subtle rustling sound.

Rocks and ancient tree remains are interlaced, and the surface is covered with traces of time - water erosion, biological erosion, and mineral precipitation have all left unique marks here.

He even found traces of Grindylow in the water plants floating in the distance.

After thinking about it, Zhang Xiao took out his magic wand and cast a head soaking spell on himself. The clear air suddenly poured into his lungs, and he let out a long breath.

It's okay, there is indeed some distortion. It would be better if the Bubble Curse could be limited to the mouth and nose.

Taking out the intercom issued in the first round, Zhang Xiao said in the bubble:

"Let's try the power of the spell and see if there is any difference from what it is on the ground."

"Okay, I'll do it first."

Cedric's voice was filled with bubbles in response. He hovered not far away, pulled out his wand, and fired a disarming spell at Zhang Xiao as planned.

There was no shining magic spell flying out, but a boiling water column pouring out from the tip of his magic spell.

Zhang Xiao successfully dodged the water column with just a slight slide.

“It’s slower, but it’s not that noticeable.”

After summarizing, Zhang Xiao continued:

"Try the power again."

Cedric's wand once again sprayed out a stream of boiling water. Zhang Xiao's body suddenly lit up with bright golden light, and he withstood the blow.

Feeling the vibration of the golden light, Zhang Xiao closed his eyes and thought deeply for a while before saying in front of everyone's nervous eyes:

"There is indeed attenuation, probably only 50%-60% of normal."

The following series of tests showed that underwater and on the ground are two completely different environments.

The distance, power, and effects all declined to varying degrees, and Hermione, who was responsible for recording, became more and more serious.

Even for Zhang Xiao and Neville, the hand-to-hand combat they are good at is actually severely limited in the water.

In the water, the source of life on earth, the gap between everyone seems not to be that big.

After completing the experiment on magic spells, Zhang Xiao began to experiment with some of his own things.

First of all, the effect of the spell is gratifying, and the "Tongtianlu (Youth Edition)" released with the magic wand is not affected at all.

Zhang Xiao actually thought of this. It was an illusory spell in the first place, so it would be strange if it was affected by it.

However, the effect of the thunder talisman is greatly weakened, and the fire talisman is very effective, similar to the principle of underwater bombs.

What surprised Zhang Xiao the most was the water-avoiding talisman. After using this talisman, the water around the body was immediately drained away. It was only four or five inches away from the body, but it made the body dry and comfortable.

It's like a head soaking spell has directly enveloped the whole body, but it is difficult to move and needs to find another way to move.

Zhang Xiao couldn't help but think of Sun Dasheng, who was omnipotent in heaven and earth. He was also not very familiar with the activities in the water. When he got into the sea, he had to make hand gestures and recite incantations to separate the waterways, and he couldn't even swing an iron rod.

In short, it's okay to survive, but it hurts your crotch in a fight.

Keeping all the questions in mind, the little wizards discussed it and continued swimming towards the bottom of the lake.

This time I simply wanted to try out what the deepest part of the lake felt like.

It's just that the depth of the Black Lake is not deep, no more than a few dozen meters at most. This is already a relatively deep lake, like several large lakes in my hometown, such as Hongze Lake and Taihu Lake, the deepest is only four or five meters.

This time they simply conjured a rope and asked Malfoy to pull them and run, who could swim the fastest.

In the last half hour, the little wizards went to visit the mermaid village, which was a rough stone dwelling. In the center of the village, there was a tall rough stone mermaid statue.

The mermaids were surprised by the arrival of the little wizards. They kept talking around them, sounding like they were singing.

But no one understood the mermaid language. In the end, the enthusiastic mermaid stuffed a bunch of fish into their hands, the kind tied with water plants.

In desperation, they could only put it away. As a return gift, they gave some shiny things. The fishman liked this very much.

I don't know where the big squid went, I didn't see it.

Taking advantage of the time, Zhang Xiao made an upward gesture to everyone.

It's time to go back.
