In the cold, damp classroom below, the walls were lined with green glass jars, and the soaked taxidermy insides made people shiver, but that wasn't the main reason for Harry Potter's coldness.

"I don't think you opened a book before school started, did you, Potter?"

Snape's words were still so annoying, and Clark watched with relish as he bullied Harry.

To be honest, as a teacher, Snape's behavior was very unprofessional.

It is a despicable act to take advantage of one's position as a teacher to embarrass and humiliate one's own students.

This is also in the British wizarding world, if it were changed to Huaxia, the teacher qualification certificate would have been revoked a long time ago.

What? Hogwarts teachers don't need to take this test, they don't have a license? So it's no wonder.

By this time Snape had already begun to ask the third question, still ignoring Hermione's trembling arm.

"Potter, what is the difference between scapular aconitum and wolf venom aconitum then?"

At this point, Hermione stood up, her hand reaching straight for the ceiling of the basement classroom.

"I don't know," Harry whispered, "but I suppose Hermione knows the answer, so why don't you ask her?"

"Poof!"

Clarke couldn't help but laugh as Harry looked down at him and almost gave him a thumbs up when he winked at him.

Snape, of course, was upset.

"Sit down," he yelled at Hermione, then glared at Clarke.

And Clark lowered his head, not daring to look at him, as if his whole body was full of "Don't point me!" Don't click me! The cry of the voice.

"Maybe our 'Son of Gryffindor' can help his stupid classmate answer that, after all, aren't you the embodiment of knowledge?"

The Slytherin students in the audience all covered their mouths and laughed, while the Gryffindor students on the side looked at him worriedly.

But in Hermione's eyes, the corners of Clark's mouth clearly showed a smile that had succeeded in planning.

At this time, his body stopped shaking, his head was raised, he stood up steadily, straightened his waist, and looked directly into Snape's eyes.

"Scapholoid Aconitum scapulata, also known as lupus venom Aconitum and belonging to the Ranunculaceae family, is a medicinal plant that can be purchased in the Muggle world, and they are collectively known as Aconitum.

Among them, the scapular aconitum is light in color and large in size; Wolf venom aconitum is dark in color and small in size. In herbalism, the two are only different in terms of toxicity due to the difference in the growth environment.

But in the occult, the boat-shaped aconitum symbolizes the water element, while the wolf venom aconitum symbolizes the earth element. As a result, potions are handled differently depending on how they are handled.

If you want to take advantage of their toxicity, then scaphoid aconitum needs to be soaked in a solution, while lupus aconitum needs to be ground and baked. If it is to remove the toxicity, then the two methods can be reversed. ”

Clark answered directly from the last question, and the details of this content instantly shocked all the little wizards, and Hermione even looked at him with stars in her eyes, tilting her head and looking at him with a look of adoration.

"Dung stones, also known as bezoars and sheep treasures in the East, can be found in the stomachs of goats and cows. Not every goat or cow has them in their stomachs, though, and if you're looking for them, it's best to look for the ones that are emaciated and have a bulging belly.

Of course, if you don't want to be so troublesome, go directly to the newly opened Transcendent Magic Shop at 1-38 Diagon Lane, report my name, and you can get a 20% discount. ”

Clark made a little joke to liven up the atmosphere, but under Snape's gaze, none of the students dared to laugh out loud, and he could only continue.

"The word bezoar comes from the Persian word 'pâdzahr (پادزهر)', which literally means 'to prevent poisoning'. It can be seen that the detoxification of dung stone has been discovered by Muggles a long time ago.

However, in the occult, the stones in the cow's stomach possess extremely stable magical properties, inerting the potion's reaction and consolidating it.

Therefore, in addition to being used for detoxification, potions and alchemists often use it as an inhibitor and an insurance mechanism for dangerous experiments. ”

His eyes were blazing, how could he still look like a scumbag just now, and this last question, he was going to give Snape a fatal blow.

"Narcissus root powder can be added to wormwood infusion to make a powerful hypnotic drug, also known as life and death water, living hell decoction.

But compared to Madam Pomfrey's favorite dream potion, this hypnotic pill has extremely strong side effects, making people groggy and unmotivated for a long time, like a walking corpse.

On top of that, because of the wormwood infusion, the whole potion has a bitter taste that is hard to swallow, and even when added to spirits, it is difficult for people to ignore its taste, which is really inconvenient.

But medieval witches thought of a better way to incorporate it into perfume and apply it to specific areas.

When they get close to the object they want to bewitch, the alcohol in the perfume will volatilize with the drug, so that the other person will be quietly hypnotized, this method is very hidden, and it was very popular at the time, until the aphrodisiac was invented. ”

Clark paused.

"My account of the effects of narcissus root powder and wormwood infusion begins in the penultimate line of page 7 of Libasius Polac's Advanced Potions Making, entitled "The Potion of Living Hell", a fifth-grade potions textbook.

The rest of the usage is in the third-grade History of Magic textbook, which you can find in the chapter "Medieval Witches". But that's just the books. ”

He looked at Snape and said slowly:

"In fact, in Potions, the 'Living Hell Potion' actually has another occult hidden effect.

Legend has it that in the Victorian era, a potion master was devastated by the death of his wife, so he developed the potion, and in the flower language of the period, narcissus was a lily, which means 'my remorse sleeps with you', and wormwood infusion, with a sweet and bitter taste, symbolizing extreme sadness, pain and remorse. ”

Snape subconsciously avoided Clark's gaze, and Harry seemed to see a faint flash of tears in his eyes, which made him feel that he must be dizzy. Will Snape still cry?

"The two are combined, and the lilies fall into the bitter wormwood juice, which means 'I deeply regret your death and live a hellish life of grief ever after.'"

This property perfectly illustrates the effect of the 'Living Hell Potion', which is rumored to have been concocted by a clever potions master to reunite with his lover's soul in a coma and make him reluctant to wake up.

Therefore, this medicine is also called 'unswerving love'. ”

After Clarke's last sentence, Harry was puzzled, and Snape's face was tense, and a pair of originally empty eyes, full of inexplicable emotion, looked at the specimen jars on both sides of the classroom.

Even the most sluggish person could guess that Clark's words must have touched Professor Snape's heart when they saw his expression.

And a sensual girl like Hermione, after listening to Clark's explanation, couldn't help but redden, as if she was sad for the romantic love more than a hundred years ago.

The entire classroom was silent, and a low pressure lingered above their heads, making the young wizards feel like cicadas.

After a while, Snape looked away and said in a bad tone, "Why don't you write it down!" ”

The classroom suddenly resounded with the sound of brush-brushing, and then Snape said dryly, "Gryffindor plus five points." ”
