Chapter 786 Sound Wave

"Crawfish?" Harry was a little shocked by the number of things at the bottom of the lake. The light of his wand swept across and he could see the red bottom of the lake.

He was a little confused and asked subconsciously, "What is that?"

"A very ferocious freshwater shrimp...the shell is red and very hard." Cedric gestured, "They are usually this big. By the way, they are very ferocious, very ferocious!"

Harry had already heard Ced's fear of this kind of crayfish from his description. After all, he emphasized it three times in a row!

Then here comes the problem.

"Robert, why would he keep this thing?" Harry asked doubtfully, "Since it is such a dangerous creature, I mean, according to his usual style, shouldn't he keep a respectful distance from it?"

After staring straight at the bottom of the lake for a while, Cedric couldn't help but swallow his saliva and said confidently, "Because the lobsters are delicious!"

Harry was stunned, his expression was stiff, and his mind seemed to be stuck.

Cedric didn't seem to notice his abnormality and happily introduced, "Although this kind of crayfish has very little meat, it is surprisingly delicious and juicy. Especially after it is cooked in a spicy way, it doesn't have any earthy smell at all." have……"

He couldn't help but lick the corner of his mouth, his eyes sharp, "You don't know? We almost turned the Hogwarts Castle upside down, just to eat these crayfish..."

"Isn't it called a crayfish?" Harry discovered the blind spot.

"It can also be called crayfish." Cedric said, "I remember that's what they call it in the flower country, spicy crayfish. Yes, this name is so appropriate!"

He looked at the crayfish with some pity and sighed, "It's a pity that these guys are too fierce, otherwise I would have to catch a few and go back to eat... Well, it may not be possible today, the red oil will solidify on the shrimp shells, so if you sell them What a difference! It’s best to eat this with ice-cold butter beer in the summer! We’ve decided to have spicy crayfish at our last dinner party this school year!”

As he spoke, Cedric drooled and looked very greedy.

Harry said that he was completely unable to associate the menacing creatures with pincers at his feet with "Don't mess with me" written all over their bodies with delicious food.

"But why are crayfish in the conch?" Cedric was a little confused, but Harry didn't know the answer.

He could only shrug and said helplessly, "Maybe they are... imitating their brothers?"

"My own brother?" Cedric was a little confused, not knowing what Harry was talking about.

"They're hermit crabs," Harry explained. "You know, they're the ones on the beach that like to get into conchs and make their nests."

"Oh." Cedric gave a meaningless response, "Then it is a hermit shrimp. By the way, can a hermit crab do this? Attack others silently?"

Harry was immediately stuck. This definitely involved his knowledge blind spot. As an ordinary student, he naturally didn't know many things about hermit crabs. In fact, he even knew the term hermit crabs within ten years of his enrollment. When I visited the aquarium for the only time in my life in several years, I heard what the cleaners said.

"This...maybe?" Harry scratched his head, "But do you know how they do it?"

Forgive him, although he saw a red crayfish with fangs and claws under the conch and the crayfish surrounding the conch, he really didn't know how these things could silently attack him and Cedric's.

Perhaps they were using some kind of attack that was more mysterious than magic?

At this moment, Seid stepped aside with an exclaim. His swimming skills were already relatively proficient, and he was able to slightly convert the resistance of the water flow into power. The sudden attack flew out against the heel of his shoe. .

Harry saw a broken black heel flying far away.

"Fortunately I wore shoes." Cedric said with lingering fear, "otherwise my heel would be gone."

Harry didn't want to complain about how well the shoes protected his heels. When he was staring at these creatures just now, he could only see the hermit shrimp moving the conch on its body. After that, nothing came close, and there wasn't even much water flow. change.

"I suddenly thought of what it was." Cedric raised his eyebrows, "If it's not a magic spell or water flow, then it's probably an invisible substance... Well, I mean, I think it should be A sonic wave.”

"Sound wave?" Harry looked at Cedric in confusion, "Sound wave is so powerful?"

"I don't know, but we can guess. I heard that the Fat Lady has been working on shattering goblets with her high notes." Cedric shrugged, "Then sound waves must be very dangerous, right? "

Harry thought he was right.

"Is there any way to counter sonic attacks?" Harry frowned and thought hard.

"I think we thought wrong." Cedric said thoughtfully, "What we should be thinking about is how to quickly escape from the range of the hermit shrimps."

"Wha, what?" Harry didn't react yet.

Cedric pointed to the hermit shrimp at his feet that was still trying to flip the conch on his back, and said with certainty, "We don't have to fight it at all. As long as we run out of its sonic attack range, we won't be hurt anymore."

Harry responded in a daze, and then realized that Ced's intention was to let him swim faster.

"And its attacks actually have time intervals." Cedric said confidently, "I counted, maybe once every three minutes?"

Harry felt that with his ability...

Tears came to his eyes just thinking about it. How could he swim 100 meters in three minutes?

So desperate.

For wizards, being physically stronger than Muggles allows them to swim farther.

Three minutes is enough for an ordinary person to cover a distance of 100 meters, except for landlubbers.

Harry felt like a landlubber. Cedric had taught him very carefully, but his swimming skills were still impressive.

To put it simply, he was the kind who fluttered for a long time, then looked around and found that he was still where he was.

Sometimes Harry couldn't help but think that maybe he wasn't really suitable for swimming... maybe he should try to learn the Fish Transformation Charm?

I heard that for fish, swimming is instinctive, and if you can turn into a fish, then there won't be any problem with swimming, right?

The more he thought about it, the brighter Harry's eyes became, and he was obviously ready to work hard to learn advanced transformation spells.

It's a pity that his strength is in Defense Against the Dark Arts, not Transfiguration. Even if he has made up his mind to study hard and make progress every day, he will forget it as soon as the momentum wears off.
