Looking at the figure who walked from the doorway—

"Oh my God!" Ginny Weasley covered her mouth and couldn't help but mutter, "How could it be!"

She wasn't the only one who reacted like this......

Because the elder who appeared from the door, all of them were actually very familiar...... But it was completely unexpected.

"Why Professor Dumbledore?" asked Ginny in a low voice as she leaned into Luna's ear.

Many of those present had the same questions as her, but Luna Lovegood didn't seem to be among them.

"Because Professor Dumbledore is the Headmaster!" Luna said with a look of cause on her face, without any surprise on her face, "Is there anything strange about this?"

"Forget it, I can't talk about you. Ginny stuck out her tongue and turned her head away.

And Albus Dumbledore had already strode to the podium at this time.

......

"I know many of you will be surprised......" Professor Dumbledore's voice was only slightly louder than a whisper, but the class could clearly hear every word he said, "After all, your Potions teacher, after just a short Christmas, was suddenly transformed from the likable Professor Horace-Slughorn into a bad old man like me......"

There was a low laugh among the students, but it stopped abruptly as Dumbledore looked up.

"Of course I can assure you...... Two months at most, and I'll return Horace to you in its original form!" Dumbledore explained with a smile, "But at this stage, it is quite difficult to find a temporary Potions teacher for two months. ”

"As most people think, your Defence Against the Dark Arts teacher, Professor Severus Snape, is theoretically the right fit...... But Severus had too many things to do during this time, so he turned down my invitation!" Dumbledore paused and continued, "So as a last resort, I can only take this place when I come!"

"Of course, I'm not sure if I'm the right person for this position!"

A brief opening remarks with Albus Dumbledore's characteristic sense of humor...... The students of the four houses present pricked up their ears and listened carefully to the sound coming from the podium, even the Slytherin students who pretended to be "dismissive".

No one took Professor Dumbledore's last words to heart...... Anyone who knows even the slightest thing about Albus Dumbledore will know that the greatest achievement of the Hogwarts Headmaster's life, apart from resisting the two successive Dark Lords, was the discovery of twelve uses of dragon blood, which is the most profound content of Potions.

Looking at the nervous and curious eyes, Dumbledore said gracefully, "I think your two former Potions teachers have mentioned to you that the reason why you came here is to learn the precise science and rigorous craftsmanship of potions preparation...... Potions are complex, mysterious, and wonderful, and a myriad of hazy veils loom over them, and all we need to do is remove the veil upon them...... So, can anyone tell me what a potion is?"

The entire classroom fell silent.

It's not for any other reason...... And purely because, the question that Dumbledore asked was too simple.

Ginny and Luna glanced at each other, but someone else had already raised their hands first.

"Very well, Miss Bobin, you have to answer this question. ”

Dumbledore was named by Melinda Bobin, a beautiful Ravenclaw girl.

"Professor Snape taught us ......," Bobin replied, looking up and confidently speaking, "potions are potions made of magic...... They can help us increase our prestige, brew glory, and even stop death ......"

After answering, she glanced quietly at Albus Dumbledore.

However, Professor Dumbledore did not agree with her answer for a while, nor did he raise any objections.

He just smiled and said, "Pretty standard answer, I can't say what is wrong in your answer...... But I must point out that if you think that potions are merely potions made by magic, that is a rather narrow view. ”

Melinda Bobinlen was there, looking visibly at a loss.

But Albus Dumbledore came to her side and patted her on the shoulder, realizing that she was sitting down.

"Then let's change the question!" Dumbledore didn't continue to look at Meranda Bobyn, but asked again, "If we need a powerful antidote in a very urgent situation, then our best bet is ...... Very well, Miss Weasley, you answer that question. ”

The first to raise her hand this time was Ginny Weasley, who raised her hand high before Dumbledore could finish speaking.

"You can use the bezoar, Professor Dumbledore!" Ginny said without hesitation.

Obviously, this is also the answer Dumbledore wants: "Very good, a piece of bezoar can remove the toxicity of many complex poisons...... Gryffindor plus five points. ”

As he spoke, Dumbledore waved for Ginny to sit down as well.

"What is a bezoar, a stone taken from the stomach of a cow...... Rather, a type of stone that is produced in the liver and gallbladder of cows...... Dumbledore continued, "It's a pretty practical potion, but unfortunately it doesn't require any kind of magic to be created. ”

The classroom fell silent again, and everyone was savoring what Dumbledore had just said.

"Of course, I'm not tearing down your former Potions teacher's desk, but I have to say that it would be quite a narrow view to think that potions are just magic-made potions!" Dumbledore's face gradually became serious: "In fact, even Muggles use bezoars frequently in many of their medicines......"

Dumbledore only made a brief mention of a Muggle, and then abruptly stopped.

"So let's move on to the next question...... Miss Weasley!"

Ginny Weasley stood up confidently again.

"Now that we know that bezoars are a powerful antidote...... Excuse me, then, why does it detoxify the poison?" Dumbledore asked with a mysterious smile.
