No matter what kind of potion it is, if you talk about the efficacy of the medicine regardless of the dose, you are a hooligan.

It is also a healing potion, and even a one-centimeter cut with a low concentration is difficult to heal. But if the concentration is high enough, it will heal quickly even if your neck is almost cut off – of course, healing doesn't mean it's lifesaving, because no one can survive a cut neck.

As for the power of Thunderbrew, Snape already had a clear enough understanding.

Snape admits that it's amazing and powerful, but it's just that.

While theoretically this power is enough to kill a wizard, wizards are not stakes and won't stupidly stand there for you to hack, and ordinary wizards can use armor to block attacks of this power.

But what if the power of Thunder Brew could be even greater? What if Thunderbrew was powerful enough to break through the armor of a regular wizard?

It was on the basis of such doubts that Snape's gaze was so intense.

Responding to Snape's inquiry, Ash replied after a moment's thought:

"It's true that you can make a more powerful thunder brew, but the stakes are high."

Ash is systematically assisted, so he never thinks about the risk of failure.

But if other wizards want to try to mix thunder brew, the slightest mistake can kill them.

Receiving an affirmative reply, Snape did not hesitate to say:

"You can use the rest of the ingredients as you like, that's what I said at the beginning."

"Besides, I'd like to be able to buy the potion recipe for Thunder Brew from you, how about 30,000 Galleons?"

Ash shook his head at Snape's offer.

Snape frowned slightly, and said in a deep voice:

"How many Galleons do you want to sell?"

Ash shook his head again and said calmly:

"No, I mean, no."

"If it's just Professor Snape and you want to mix Thunderbrew, you don't need any compensation, just promise not to give the recipe to anyone else."

Snape looked at Ash with a deep look, of course he knew what was free and the most expensive.

Don't Galleon, it only shows that Ash is bigger!

Snape said lightly:

"If you have trouble at Hogwarts that you can't solve, you can come to me."

It's a promise, but it's limited to Hogwarts.

"I will, Professor Snape."

Ash smiled back, then turned back and continued to blend the thunder brew.

The corners of Snape's eyes twitched slightly, Ash obviously swore not to give up until his stock was exhausted, he didn't want to have the opportunity to mix his own thunder brew in a short period of time - leech juice and fig fruit were not hard to find, and they could be bought in Hogsmeade.

However, the Corpse Stink is different, this material can only be obtained from Yin corpses that are old enough, and each Yin corpse has and only one copy. Therefore, if you want to get enough corpse spirits, you can only look for the tombs of those ancient dark wizards - such dark wizards usually cultivate a large number of Yin corpses in their tombs to protect their tombs.

So normally, it's hard to find a corpse on the market, and Snape doesn't have much in stock.

But the words had already been spoken, and he couldn't change his words, so he could only watch with a dark face as Ash consumed his inventory.

An hour later, Ash put away the flask full of thunder brew and boosting potions, and said with sincere gratitude:

"Thank you for your generosity, Professor Snape."

Snape didn't answer with a dark face, just watched Ash leave with a cold eye.

The hour had given him a full taste of Ash's talent for potions—he retracted his assessment of Ash, at least when it came to potions, Ash was more gifted than he had thought.

But, but! He still couldn't accept the use of magic to mix potions!

This heresy must be banned!

"Ash!"

Leaving the Potions classroom, Ash immediately saw Kassandra, Hermione, and Hallie sitting on a bench in the hallway outside. Kassandra bowed her head to Ash in a reserved and haughty manner, Hermione, who was reading, looked up, and Hallie happily jumped up from her chair and beckoned to Ash.

"Why are you here?" Ash was a little surprised.

Hallie said seriously:

"We're waiting for you here."

Seeing Hermione, who was obviously a little dissatisfied, Ash saw that she was looking at the book angrily, and deliberately asked:

"But aren't you going to the library to study?"

Harry's expression fell, and Ash asked with some amusement:

"You won't drag them here to wait for me because you don't want to study, right?"

"No, it's not ......," Harley denied, but her voice was a little quiet.

Kassandra asked, confused:

"Why have you been with Professor Snape for so long?"

"I asked Professor Snape some questions about potions."

Ash explained, handing three flasks to the trio.

The three little ones took the potion bottle curiously, and looked at the dark purple surging inside.

Hermione asked, puzzled:

"What kind of potion is this?"

"Thunder Brew."

Ash explains:

"A potion for attacking, if you are in danger, you can throw it at the enemy, of course, don't use it lightly on other students. Don't get too close, otherwise it's easy to hurt yourself. ”

Hallie nodded as if she didn't understand, and Kassandra asked thoughtfully:

"That's what you asked Professor Snape?"

"Yes." Ash did not deny it.

Hallie asked, expectantly:

"Ash, we're going to Hagrid in the afternoon, do you want to go with us?"

"I'm afraid not, I have classes in the afternoon." Ash shook her head slightly, and Harley couldn't help but be a little disappointed.

Just as Professor Snape had left the Potions classroom, his face darkened when he saw Ash standing around the corner of the hallway. Just as he wanted to snort coldly to express his dissatisfaction, Yu Guang found Harley and the others standing next to Ash.

As soon as Hallie saw Professor Snape, she said obediently:

"Professor Snape, thank you for instructing Ash in making potions."

Snape's originally cold eyes immediately softened, and he said in a gentle voice:

"You're welcome, this is what I should do as a professor, if you don't understand anything, you can always ask me."

Seeing Snape go away, Hermione whispered:

"Professor Snape doesn't seem to you like anyone else."

"Is there one?" Harley blinked, confused:

"I feel like he's the same to me as Kassandra."

Hermione rolled her eyes, of course it's the same for you, because Professor Snape treats Kassandra very favorably!

She pondered the language for a moment and explained:

"Professor Snape, for example, treats Neville and Ron completely differently than you do."

Hallie said as a matter of course:

"That's because they've done something wrong, and it's normal for Professor Snape to be angry because they can go wrong with such a simple potion and bruise themselves?"

Kassandra didn't have a good breath and said:

"You really don't have any self-consciousness at all!"

"Do you think you'd be better off than they would have ended up without me?"

"Hey~" Hallie tilted her head, trying to get by.

Kassandra made a small face and said solemnly:

"It's useless to pretend to be cute! I don't eat your set! ”

"Forget it today, but tomorrow you have to go to the library with me to study."

Hermione added, "All day. ”

"Eh!!"
