"What?" Miss Ginny Weasley almost blurted out.

She looked at Professor Albus-Dumbledore in some surprise and blinked in confusion.

"That...... Why is the bezoar able to relieve the poison of the poison......" Ginny muttered, "Uh, I remember...... Professor Arseny Spoh said this in his introduction to the bezoar in his book "Magic Potions and Potions"......"

"Very good...... So, how did Professor Spoh make such a judgment?" asked Dumbledore, with a kind expression.

"This ......," Miss Weasley was speechless, blushing and whispering, "I'm sorry...... I do not know...... Professor ......"

"Well, that's nothing!" Dumbledore smiled and waved his hand at Ginny, motioning for her to sit down first.

And under the podium, many students couldn't help but whisper to each other...... Ginny Weasley was clearly not the only one who wondered why the professor would ask such a somewhat inexplicable question.

Then he glanced at the crowd, raised his voice slightly, and said, "I think I'm sorry for that...... Because on your faces, I can guess that none of you have ever thought about it...... Nor has anyone ever questioned Professor Arseny Spoh's description in the book Magic Potions and Potions......"

“...... Of course, I am not disrespecting Professor Arseny Spoel, but simply questioning the rigor of his conclusions......" Professor Albus Dumbledore continued to explain calmly: "For example, he only told us very roughly that bezoars can be detoxified...... But he didn't specify in detail which types of toxic bezoars could achieve good results and which types of toxic bezoars could not do anything about them......"

"At the same time...... There's a lot more to discuss...... For example, how much bezoar will have the best effect, and how much more will have the opposite effect...... Under what conditions such as temperature can help the bezoar achieve the best effect, and under what conditions, the effect of the bezoar will be very poor......"

Professor Albus-Dumbledore's remark was something that many of the students looked at each other a little bit of.

“...... In fact, if you look closely at the History of Magic, you will find some references......" Dumbledore continued: "For example, in 1379, the Roman apothecary Alvalo Cecilion mistakenly ingested a small tube of Loba worm's venom for Motra rat juice, and after realizing that something was wrong with his body, he quickly took a large amount of bezoar ......"

But the end result was that Mr. Cecirio died three days later...... In fact, although the venom of Loba worm causes a certain degree of neurasthenia, it is not fatal...... Although there is no detailed description of it in the History of Magic, my guess is that he most likely died of poisoning after an overdose of bezoar......"

Professor Dumbledore glanced at the crowd, then stopped the story he was telling.

Then, calmly, he called by name, "Do you have any questions, Miss Greengrass?"

Astoria Greengrass, who was at the Slytherin table, stood up and asked softly, "Huh...... Professor Dumbledore...... Do you mean that your Potions course is going to take us on a journey through the principles of potions?"

"Understood correctly...... Ten points to Slytherin!" Albus Dumbledore smiled:

"Yes...... I want you to understand potions not just by the potions themselves, but by a deeper perspective...... Their mechanisms, their principles, and the changes they produce......"

......

This unique Potions class began.

They no longer use cauldrons, nor do they wave their wands...... Albus Dumbledore had prepared a lot of "cute" guinea pigs for them.

And, of course, there's a vial of Loba worm's venom and pieces of bezoar ground into powder.

Professor Dumbledore instructed them to give the mice different doses of venom and then different doses of bezoars for detoxification...... At the same time, use the "growth charm" to speed up the growth of the mice and observe the changes in their appearance.

At the same time, Professor Dumbledore instructed them on how to use the "cutting technique" and a sharp knife to "dissect" the dead mice, and observe the changes in their internal organs under some strange instruments......

Finally, Professor Dumbledore instructed them on how to record what they observed and come up with a "conclusion"!

......

If any other professor has made such a subversive move in the classroom...... Then he will definitely face the doubts of many students, and even the parents of students.

But now that it was Albus Dumbledore standing on the podium, things were a little different.

After all, Dumbledore is considered the most outstanding wizard of the twentieth century...... He is also one of the finest alchemists of the twentieth century......

Two hours later, as the bell rang, Professor Dumbledore left the Potions class.

A group of students were left behind, and they continued to discuss.

"It's amazing, isn't it......"

"Especially the thing that the professor called 'microscope'...... It's amazing magic......"

"I didn't expect that there were so many weird little bugs on our skin...... It's horrible......"

The students of the four colleges left the class on their feet.

"It's definitely ...... It's the funniest Potions class I've ever taken!" said Luna Lovegood, who was almost the last student to get up from her seat, to Melinda Bobin beside her with a serious face.

"It's interesting...... Miss Bobin looked a little worried, "but Luna, don't you forget, is the exam going to be relevant to our lessons?"

"I think you're thinking too much, Melinda!" Luna covered her mouth and giggled, "Don't forget...... But Professor Dumbledore taught us...... Will he make it impossible for us to get our diplomas?"

"That's ......" Miss Bobin nodded, she picked up her backpack, only to see Luna sit down again, "What's wrong, Luna...... Aren't you going back?"

"Wait a minute!" Luna blinked, then lowered her head again, pointing at the strange instrument, "You go back first...... I'm like, I've found something interesting!"
