Chapter 186 Mandrake and Ultrasound
After Professor Sprout stepped into the greenhouse, the scene in front of her made her smile with satisfaction.
The students stood quietly, and no one dared to touch the magical plants.
It seems that they have remembered the warnings and teachings in the first class last year, and no little wizard dared to do anything wrong in the third greenhouse.
The third greenhouse is more dangerous than the first greenhouse.
The poisonous tentacles hide in the dark corners. Its seemingly weak branches actually contain deadly venom, and its thorns are also covered with poison, ready to give the invaders a fatal blow at any time.
On the shelf not far away, a group of carnivorous plants swayed, shaking their heads constantly, exuding an attractive aroma, luring innocent creatures to approach.
However, once a creature approaches, these carnivorous plants will swallow it without hesitation, and then slowly digest the prey with their serrated leaves and powerful digestive juices.
There is also a pink dancing grass, its leaves are pink and cute, swaying in the wind, dancing gracefully.
However, this beautiful appearance hides a crazy power. Once someone eats it, they will dance like crazy until they are exhausted.
In short, these are plants whose DNA was recorded by Ye Ting’s little flower buds to defend the manor.
The entire greenhouse looks beautiful, but it is actually full of murderous intentions. Every step is full of unknowns and dangers.
“Okay, little wizards, today we are going to give a magical plant a new home!” Professor Sprout pointed to the rows of plants on the ground and asked with a smile, “Who can tell me what this little guy is called?”
Before the voice fell, everyone hadn’t seen the appearance of the plant clearly, and the humanoid self-propelled encyclopedia Hermione couldn’t wait to raise her white arms.
“Miss Granger, it seems you can’t wait, you answer.”
“Yes, Professor! Its leaves are elegantly oval, blooming white or blue flowers, and the fruit is round and cute…” Hermione analyzed accurately, “This is undoubtedly the Mandrake!”
“Excellent, Gryffindor gets five points for this!”
Professor Sprout nodded with satisfaction, and the smile in his eyes became even stronger, “Now, everyone can get closer and observe carefully, but remember not to confuse the Mandrake with its brother, the Mandrake. Before they bloom, they are as difficult to distinguish as twins, but the position of the branches is slightly different…”
The little wizards gathered around, staring at the Mandrake without blinking, for fear of missing any details.
Professor Sprout saw this and continued to talk:
“…and the mandrake has another amazing feature, which is its rhizome. Its end will curl and fork cleverly, and the overall shape is like a miniature human, which is extremely wonderful.”
As he spoke, Professor Sprout gently waved his wand, and a blackboard appeared out of thin air, with a clear image of the mandrake rhizome on it. It looked like a naturally formed miniature human statue.
At this time, Anthony raised his hand: “Professor, can you let us see the real thing with our own eyes? This may be more intuitive.”
His words immediately resonated with the students, and many of them nodded.
“Haha, of course, children’s curiosity is always the most precious treasure!”
Professor Sprout laughed heartily, but then changed the subject, “But before the show, I have to remind you that the rhizome of the mandrake is quite dangerous. Who can tell me what its danger is? Well… Miss Granger, it seems that this question has to be answered by you again!”
Professor Sprout gently raised his hand, signaling Hermione to reveal the answer.
“The cry of the mandrake is a scream that is enough to kill people.” Hermione blurted out.
“Absolutely right, Gryffindor will add another ten points for your wisdom!”
Professor Sprout praised generously, “Do you know? The great British dramatist Shakespeare has such an unforgettable line in his masterpiece Othello…”
The witch coughed lightly and recited slowly in an aria that seemed to penetrate the soul:
“What a disgusting sound! Just like the sharp scream of the mandrake when it was roughly pulled out of the soil! Any human being who hears this sound will fall into madness. It is a curse from the abyss…”
The students looked at each other in surprise at Professor Sprout.
The witch looked ordinary – her hair was casually scattered, a patched hat was buckled on it, and there was a little dirt on her clothes. She didn’t look like a professor, but an ordinary gardener.
However, who would have thought that this witch with a plain appearance was actually a hidden drama lover?
Moreover, when she sang with that soprano, the voice was so beautiful, which was very consistent with her fat figure – at least it was much better than the fat lady at the entrance of Gryffindor.
This strong contrast caught the students off guard.
After the singing, Professor Sprout raised a challenging question:
“There are different opinions in the academic community about the scream of the mandrake. Is there anyone willing to stand up and share the different opinions you know? ”
This time, Hermione did not raise her hand as usual, and a trace of confusion flashed in her eyes.
Obviously, this question touched her blind spot in knowledge.
Seeing that no one raised their hands, Ye Ting finally took action.
“Mr. Ye Ting, are you willing to share your views?” Professor Sprout’s eyes were full of expectations.
“Some herbalists believe that mandrakes do not make real sounds.”
Ye Ting said slowly, “They believe that it is the hallucinogenic toxins contained in mandrakes that cause the poisoned to have auditory hallucinations. This auditory hallucination makes people mistakenly believe that mandrakes can scream, but in fact, it is just the toxins that are at work. ”
Hearing this, the little wizards cast admiring eyes on him.
“Great, Ravenclaw is ten points!” Professor Sprout’s smile became even brighter, “Ye Ting, have you also studied the latest article in the magical plant journal “Herbal Research”? ”
Ye Ting nodded: “Of course, professor. I not only read it, but also personally conducted experiments.The experiment verified this conjecture. However, I have to say that the conjecture is only half right. ”
“Oh, tell me your opinion quickly.” Professor Sprout’s curiosity was completely ignited.
Ye Ting cleared his throat and began to talk: “In order to capture the existence of sound waves, I borrowed the sound wave detector from the Muggle world. Although this machine is made by Muggles, it can eliminate the interference of neurotoxins and magic. As long as there are sound waves, it will respond loyally. ”
“Muggle machines are interesting…” Ye Ting’s novel ideas made Professor Sprout’s eyes light up.
Ye Ting continued: “Then, I made an amazing discovery. When I pulled out the mandrake, the sound wave detector actually responded! This undoubtedly proves that the sound waves emitted by the mandrake are real. ”
Professor Sprout nodded thoughtfully: “So, the original conjecture is indeed wrong. ”
“That’s not the case, professor. ”
Ye Ting shook his finger, his eyes flashing with wisdom,
“Because the sound wave frequency displayed on the sound wave detector is actually over 10,000 Hz – Hertz is the unit used by Muggles to measure the pitch of sound. And sound waves over 10,000 Hz are called ultrasound by Muggles. This means that the pitch of these sound waves is so high that our ears cannot capture it. But being inaudible does not mean that this high-frequency sound wave will not affect us. ”
“You mean… the sounds made by the mandrake are still not real sounds?” Professor Sprout’s eyes flashed with a hint of enlightenment.
“That’s right,”
Ye Ting nodded gently, “The mandrake emits sound waves that humans cannot capture. And these sound waves turned into shrill screams in people’s ears. This proves that hallucinations do exist, but their cause may not be the toxins we are familiar with, but the mysterious ultrasound… I think that the wizard who proposed this conjecture, although he touched the edge of the truth, went astray because of his ignorance of ultrasound. ”
“It’s amazing! Ravenclaw gets another ten points for this!”
Professor Sprout looked at Ye Ting more gently, and she suggested enthusiastically, “Mr. Ye Ting, if you have time, can you come to the greenhouse to reproduce your experiment for me? I believe that your discovery is enough to write a shocking paper in the academic world and publish it in the top journals. I am happy to be your recommender. If this experiment is true, you will become a shining star in the herbal medicine world!”
“Of course, it’s an honor. “Ye Ting accepted it happily. (To read the exciting novels, go to Faloo Novel Network!)
After this conversation, the little wizards around were dumbfounded.
What sound waves? What Hertz? What ultrasound?
What are you talking about?
How come in the blink of an eye, Ye Ting has changed from a classmate to a rising star with unlimited potential in the field of herbal medicine?
The world of the big guys is really terrible.
Hermione looked at Ye Ting pitifully and sighed softly.
While she was still trying to get extra points by answering the textbook content, Ye Ting had already startedCooperating with the professor to write an academic paper.
How can this be compared?
What is a dimensionality reduction attack? This is a dimensionality reduction attack.
She began to doubt whether she could win a house cup in her lifetime?
Professor Sprout did not focus on the extracurricular content and soon continued to lecture.
“Since the rhizome of the mandrake is so dangerous, does anyone know how to safely remove the mandrake from the pot?”
Hermione raised her hand and said, “Usually we use earmuffs or beeswax to plug our ears, so we can avoid hearing its screams.”
“Very good, Gryffindor gets another five points for this!” Professor Sprout looked around, “Are there any other ways?”
Hermione shook her head. []
Professor Sprout’s eyes swept around the classroom, and finally fixed on Ye Ting, and asked expectantly: “Mr. Ye Ting, do you know any other methods?”
Ye Ting nodded: “We can remotely command the swallowtail to dig out the mandrake. They are naturally immune to the screams of the mandrake, and can even stop the grass from screaming.”
“It’s really outstanding, Ravenclaw gets another five points for this!”
Then, she explained the characteristics of the mandrake in detail, and then signaled the students to pick up the earmuffs from the stools.
A burst of scrambles suddenly sounded in the classroom, everyone scrambled to get the earmuffs, but they avoided the pink fluffy earmuffs.
Hermione quickly snatched back the two earmuffs. She put one on herself swiftly, and then handed the pink earmuff that no one wanted to Ye Ting with a smile: “Put it on quickly, 387, this is the only one left!”
“Thank you so much!” Ye Ting rolled his eyes at Hermione helplessly, but still put on the pink earmuff obediently.
It turns out that whether a person is handsome or not has nothing to do with hairstyle, but only with face.
The earmuffs that were extremely ugly in everyone’s eyes, miraculously became more beautiful after Ye Ting put them on.
Many female students covered their mouths and looked at the black-haired boy with shining eyes. They screamed: “Wow, so cute!”
“Really, how can there be someone in this world who is both smart and has an enviable face!”
Hermione muttered softly, with the corners of her mouth slightly pursed.
She quickly put on the earmuffs, and she was no longer so annoyed when she couldn’t hear the noise.
Professor Sprout also put on her earmuffs. She rolled up her sleeves, grabbed a clump of grass and pulled it out with all her strength.
Professor Sprout also put on her earmuffs. She rolled up her sleeves, revealing her strong arms, grabbed the clump of grass and pulled it out with all her strength.
However, what was pulled out of the soil was not an ordinary grass root, but an extremely ugly baby with leaves on its head, light green skin covered with spots, and looked like some kind of strange plant monster.
The professor took out a huge flower pot from under the table and stuffed the “baby” called Mandrake into it without hesitation, burying it with wet dark compost, leaving only clumps of leaves exposed.
She patted the mud on her hands.soil, took off the earmuffs, and said calmly: “Our mandrakes are still seedlings. Although their cries are not fatal, they are enough to make you unconscious for several hours. So, wear the earmuffs tightly and never take them off… Okay, let’s get started.”
Repotting the mandrakes seems simple, but in fact… it is even simpler.
Ye Ting walked forward and pulled out the mandrake. The little guy twisted his body and obviously refused to cooperate. Ye Ting was quick and cut the back of the mandrake’s neck with a knife.
The little guy fainted on the spot.
Ye Ting hurriedly stuffed it into the pot, and his movements were so fast that people couldn’t keep up.
Under the cover of the crowd, Professor Sprout did not notice the “humiliation” that Ye Ting had done to her “baby daughter”, but only saw that he was the first to complete the pot change.
Professor Sprout nodded with satisfaction and knocked on the blackboard. A row of small words suddenly appeared on the blackboard:
“Twelve seconds… Ye Ting broke the fastest pot-changing record… Ravenclaw gets five points!”
There was a burst of exclamations in the classroom – unfortunately no one heard it – everyone was shocked and admired Ye Ting’s speed.
Hermione was stunned… Is this possible?
She was almost doubting her life! .
