I was expelled from Hogwarts?

Werewolves are terrifying creatures that transform upon a full moon and attack other humans indiscriminately.

And those who were bitten, either died, or were infected into new werewolves, and then attacked others... Repeatedly.

Therefore, a potion that can make werewolves unable to transform, or maintain rationality after transformation, has been urgently needed to be developed.

The appearance of wolfbane potion undoubtedly alleviated this problem.

Of course, it's just a relief.

The reason is very simple. The wolfbane potion is extremely difficult to brew, and the steps alone can fill two densely packed blackboards... The difficulty is evident!

Therefore, this potion is indeed not within the scope of the students' study, and it is seriously out of class.

Forget about super-class, most of the ingredients for brewing potions are poisonous.

Needless to say, wolfbane grass; after eating white snakeroot grass, you will be infected with a symptom called "breast distension". Many witches used to use it to enlarge their breasts.

There is also the famous hemlock, which was contained in the poisoned wine that Socrates drank.

The little wizards all wore strict protection, but they still refused to do it for a long time, for fear that they would die young if they were contaminated with a little poison.

Snape frowned and urged:

"What's there to be afraid of? The dose is so small and you're wearing gloves. As long as you don't swallow it directly, nothing will happen! And absorbing a small amount of toxins is actually good for your body."

This made Rove think of his chemistry teacher in his previous life. When he asked everyone to do chemical experiments, the students were very afraid of being poisoned, so he comforted him and said:

"Doing more chemical experiments is good for the body. I had rhinitis when I was a child, and it couldn't be cured no matter what. Later, I entered the laboratory and inhaled ammonia for a while, and the rhinitis gradually disappeared."

His rhinitis is indeed cured, but... his head is bald.

Under Snape's repeated urging, the little wizards had no choice but to start brewing Wolfsbane potion reluctantly.

Of course Snape knew they couldn't make it, but he didn't care.

He just needed the students to use their creativity and give Lupine a little Hogwarts shock.

Snape circled around, really shocked.

Justin and McMillan's cauldron smelled like a bathroom, as if someone's septic tank had exploded... Are you sure you didn't secretly add fuel to it?

Lisa Dupin and Padma Patil's potion smelled good, but the potion was as sticky as mud in a swamp.

After Snape inquired, he found out that Padma Patil had made a little innovation by adding a little water from the Ganges River in her hometown.

Neville and Hannah even exploded with astonishing creativity. They boiled the wolf's poison potion into "Poisonous Wolf Potion". Even the outer wall of the crucible was directly corroded by the potion water.

Snape sometimes wondered why the students couldn't learn what the steps were written so clearly that they could be understood at a glance? !

People are indeed different, even the experienced Rove is stuck at a certain step.

He put the steamed bat tongue into the crucible, and stirred it clockwise three times. According to the blackboard, the color of the potion should be light green, but it turned purple at this time.

Rove and Shirley checked several times, but they couldn't find any problems. Just when they were about to start from scratch, Snape wandered over.

He just glanced at the cauldron, and a mocking smile appeared on his face.

Rove usually did not make mistakes, but Snape would have a wave of eccentricities, and now that something went wrong, why shouldn't he make a good sarcasm?

But Snape unexpectedly didn't taunt, but lazily said:

"The bat tongue has been boiled for too long, try adding a little carbon powder."

Rove raised his eyebrows, quickly grabbed a handful of toner, threw it into the crucible, and the color really slowly changed from red to green.

Snape had no intention of leaving, but stood aside and watched.

Luo Fu and Shirley looked at each other, a little helpless, so they could only bite the bullet and continue brewing the potion.

Shirley cleaned the anhinga's scales and threw them into the crucible. Rove added a few drops of the venom of the color-changing giant snail, and the color of the potion changed to cobalt green.

Snape reminded again:

"It's best to add another bottle of Potentilla tincture and simmer for three minutes on low heat, the potion will be more likely to solidify."

Wolfbane Potion didn't seem to have this step, Rove subconsciously glanced at the blackboard, Snape snorted coldly, and said impatiently:

"I improved it myself, whether you like it or not!"

"..."

Since Snape said so, of course Rove could only follow through.

Shirley was originally sitting next to Rove, but seeing Snape approaching, she had no choice but to move the stool back.

After a while, Shirley was far away from Rove and was pushed aside, and Snape took her original place.

The girl with the ponytail looked at Rove in a daze, and then at Snape who was sitting next to him guiding him, feeling a little at a loss.

It was her, it was her first, she was the one who sat there first...whether it was brewing the potion, or helping Rove with the materials!

That's her place, Professor Snape!

The students all raised their heads and looked at the picture of "Teacher, Friend and Disciple Gong" in shock. They must be dreaming, right?

"Actually, at this point, I think it's best to use werewolf blood instead of wolf blood." Snape frowned and said:

"What do you think, Scamander?"

Rove had a fart idea, he scratched his hair, and nodded in agreement.

"You think so too?" Snape said softly again: "But werewolf blood is hard to get."

Of course it is difficult to deal with, werewolves are very dangerous, and it is very difficult to kill them.

Of course, there are also werewolves who sell blood, such as poor ghosts like Lupin, but they only sell a few hundred milliliters at most, and the supply exceeds demand!

"By the way, Scamander, is the body of the werewolf Fenrir Greyback you killed still there?" Snape asked casually.

"..." Tu Qiong saw him, and he was waiting here.

Rove immediately warned: "Fenrir Greyback's body was confiscated by the Ministry of Magic."

"I know." Snape narrowed his eyes: "But I heard from Dumbledore that most of his blood and flesh were dissected by you, right?"

Rove emphasized: "Professor Snape, the wolf blood is mine."

"I didn't say it wasn't yours, look at your arrogant attitude, deduct... Hufflepuff plus five points!"

"..."

Professor Snape showed unprecedented patience, and his voice softened.

There is no way, he wanted the basilisk last year, and used all kinds of methods, such as deducting points and poisoning, but they all failed.

Not too hard, Snape wanted to be soft on Rove, playing the emotional card.

"Scamander, we can exchange." Professor Snape lowered his voice, "I have a lot of magic materials."

Rove curled his lips and said, "Sorry, I don't lack magic materials right now."

He really has no shortage of magic materials now. On the one hand, he can ask for them from Hagrid, and he can also trade them with the centaurs.

"What about the potion?" Snape raised his mouth and said, "There are many precious potions in my medicine storage."

Rove raised his eyebrows, he was really interested in this, he pondered for a moment and said:

"Professor Snape, we are teachers and students, and I won't cheat you.

Let's start with seven or eight liters of Bliss Elixir... I haven't drunk that stuff yet. "

"..."
