"Poils are a profound science and precision craft. Most people are mediocre after all, but I can lead a small number of excellent talents to create glory and even refine the elixir of immortality." Snape's ruthless eyes swept across everyone.

Alan couldn't help but tickled. Refining the elixir of immortality is really a brag. At present, only Nico Lemay can live forever. Relying on the elixir of the Philosopher's Stone, while only Nico Lemay knows how to refine the Philosopher's Stone.

Snape instantly focused his eyes on Allen.

"Mr. Drew."

"Here!" Allen stood up.

Snape walked to Allen: "From your expression, you don't seem to believe me."

Allen said honestly: "Professor Snape, I think you're bragging."

Snape's mouth twitched slightly, and a student actually said in front of his face that he was bragging. It was a novel experience.

The other students looked at Allen as if they were looking at a hero.

Snape said coldly with a look of killing people, "Why do you think I'm bragging?"

"The core of the elixir of immortality is the magic stone. Currently, only Nicklemay knows the method of refining, so Professor Snape cannot refine the elixir of immortality, let alone teach us how to refine it."

Allen's words were reasonable and Snape could not refute it for the time being.

"Very good, Mr. Drew, because you defied the professor, you deduct twenty." Snape shook off his robe and returned to continue his lecture.

Allen sat down and wanted to draw circles for Snape. He deducted so many points at once. He was really shameless.

Justin pulled Allen's clothes, and Allen looked back at him in confusion.

"You are so amazing, I'll give you a thumbs up."

Before Allen could answer, he heard Snape's voice.

"Mr. Drew and Mr. Fenlieri, stand up." Snape looked at them with cruel eyes as if he had caught a cat.

"You don't seem to have to listen to my class. It seems that you know everything. Mr. Drew, answer me, what is the function of the Posa Stone."

Alan blinked his eyes and replied, "The Posa stone is a stone taken from the goat's stomach, which has the effect of detoxification."

"So what does bubble stems do?"

"The thick juice of the bubble stems has a special effect on difficult blisters."

"What are the ingredients for treating scabies?"

"Slug, snake's fangs, dry nettles, porcupine thorns"

"What material is there in the squirt agent?"

Alan glanced at the corner of his mouth: "Professor Snape, the formula of the singling agent is monopolized by the Ministry of Magic. Ordinary wizards don't know at all, let alone a little wizard like me, but judging from the ability of the singling agent, they should have the feathers of Jueyinbird."

Snape stared at Allen, and had to say that Allen answered almost all questions perfectly.

"Sit down and don't talk."

Snape turned his eyes to Justin, and a ruthless voice rang out: "Mr. Fenlieri, how long does the compound decoction last?"

Justin's legs were weak and he said tremblingly: "I don't know."

Snape roared: "I don't know if you don't listen to the class yet, Hufflepuff, deduct ten."

The class was silent, and the sound of heartbeat was quietly heard. Even Hufflepuff, who was deducted 30, dared not refute it.

Snape sat Justin down and started today's class, refining the potion for curing scabies.

Knowing that doesn't mean you can do it. Snape stood behind and glanced around with a dead fish-like look, especially Alan, who seemed to be waiting for Alan to do something wrong.

Allen wiped his cold sweat and followed the steps little by little.

First steam and cook the slug with tentacles once, grind the snake's fangs into powder, then throw the dried nettles and ground snake teeth into a crucible and stew them. After turning off the heat, add porcupine stings. This will complete the medicine for treating scabies.

If a porcupine thorn is placed during the fire, the potion will dissolve the crucible, and a sour green smoke will appear, and a sharp hissing sound will sound.

The chemicals that flow out are corrosive, and when they touch the body, dense red, swollen, scabies will appear.

After completing the last step, Allen breathed out a breath and finally succeeded.

Snape walked past Allen and saw Allen finishing the potion, a pity flashed across his face.

However, at this moment, an explosion sounded, green potion splashed everywhere, and Justin screamed in pain.

Snape also screamed. Allen saw the two of them constantly showing scabies and retreated.

Snape endured the severe pain and roared: "Mr. Fenlieri, don't put porcupine thorns in the fire, and deduct fifty."

As soon as he finished speaking, an explosion occurred in other places, and the green juice exploded and poured onto each classmate.

It seems like a chain formation, and the person being sprayed makes mistakes one after another, forming a source of emission again.

Seeing the wailing classmates all over the ground, Allen felt cold and hurried to the corner: "Armor protection."

Allen hid in the corner and shivered, standing in the middle Snape shivered.

"Put down the porcupine thorn for me, whoever moves will die!" Snape let out a hideous roar.

...

The potion class was very peaceful this day, shocking the whole school with 90% of the victims, and the school hospital was filled with Hufflepuff and Ravenclaw's students.

Mrs. Pomfrey clamored to cancel the dangerous potion class, while Snape hid in his basement to develop the antidote, but refused to come out if he died.

Allen, safe and sound, appeared in the auditorium and instantly attracted everyone's attention.

George and Flander pulled Allen to Gryffindor's table and said excitedly: "I heard that you have developed poison and put everyone down. Even Professor Snape was caught. Can you teach us how to refine it?"

Allen shook his head: "It's not me, don't blame me, I'm innocent."

"Now the whole school knows that you can use your own medicine to translate Lavenclaw's people, and you don't even let go of your own people. It's so powerful and cruel." George became more and more excited as he said, as if he saw his medicine to translate everyone.

"Thank you for avenging me!" Harry interjected in the middle, and he was obviously very happy to see Snape unlucky.

Hermione breathed a sigh of relief.

"Luckily Allen is not Gryffindor's, otherwise the score has become a negative one now."

Allen calculated Hufflepuff's score and was obviously close to minus 100 points. It seems that Hufflepuff has to count down this semester.

Return to the public lounge, feed the cat owner first, and then lie on the bed to overcome the automatic stylus.

As for those roommates, they probably have to spend the weekend in the school hospital, and this is also the time when Allen completes the automatic pen writing.

The noisy Friday was spent in joy, and Allen also ushered in his first weekend.
