Watch Hogwarts video, Voldemort's death

"Who is Nicolas Flamel?"

"You don't even know Nicolas Flamel?"

"I don't know... Is he famous?"

"Of course, Nicolas Flamel is the only known maker of the Philosopher's Stone! You know the Philosopher's Stone, right?"

"I've heard of it. It's the alchemical tool that can make you immortal as long as you have it. It is said to represent the pinnacle of alchemy!"

Sure enough, not everyone is like Ron, who has eaten a chocolate frog without looking at the back. There are still many young wizards who are quite knowledgeable.

At this time, Harry and the other two who heard about the magic of the Philosopher's Stone looked at each other, especially Ron, who opened his mouth so wide that he could hardly close it.

"Eternal life! So this is Nicolas Flamel's Philosopher's Stone! Wait! I think I know. What is hidden in the basement is... Woohoo!"

Ron didn't finish his words before Harry covered his mouth.

"Ron, keep your voice down! Don't let everyone know! It will be even harder for us to catch the thief!"

Catch a thief?

Zhang Dong looked at Quirrell on the stage. Good fellow, if it weren't for the protagonist's halo and Quirrell's brain twitch, he had a wand but didn't insist on fighting, you would have died long ago!

Catching a thief, it's good enough that you didn't get wiped out.

But Zhang Dong didn't say anything, just continued to play the video.

[The scene turned, and a fat man appeared on the screen. It was Jacob Kowalski. In a room, he turned his head stiffly, and saw a thin old man with white hair walking towards him step by step with small steps.

Looking at the other person's appearance, Jacob swallowed his saliva and asked stiffly: "Are you... a ghost?"]

Seeing this fat man appear, the little wizards present looked at each other.

"Who is this person?"

"I don't know him. Isn't he a student's parent?"

"I don't know. He doesn't look smart."

[Listening to Jacob's question, the old man smiled gently and said, "No... I'm just an alchemist, immortal."

Jacob calmed down and said, "Um... I'm sorry I didn't knock on the door."

"Oh, it's okay. Albus told me that some friends would come to visit. Let me introduce myself, Nicolas Flamel."]

Wow!!!

Seeing this scene, almost everyone's eyes were focused on Dumbledore in the stands.

Albus Dumbledore, there is no one in Hogwarts or even the entire British wizarding world who doesn't know this name.

And seeing that everyone's eyes were on him, Dumbledore also recovered from the emotion of reminiscence.

"So, it was that time?"

"When?" Snape asked curiously. He hadn't even started school at that time, so he certainly couldn't tell what period the video was about.

But from Dumbledore's reaction, it could be seen that it was in the past, not the future.

AndDumbledore shook his head and didn't want to say anything more. Some people always think that it is his greatest honor, but in fact, it is also the most painful thing for him.

[It is only a few meters away, but Nicolae Flamel has to jog over, but it must be said that Nicolae Flamel looks more lovely.

Nicholas Flamel brought Jacob to a crystal ball. He waved his hand and two figures appeared in the crystal ball. These two figures are a man and a woman. The man is relatively young and the woman is charming and beautiful.

It is Credence and Nagini.

Nicholas Flamel waved his hand again, and the picture of the crystal ball turned, and a mature beauty with white shoulder-length hair also appeared in the crystal ball.

Seeing this figure, Jacob immediately became excited.

"That's right! Queenie! Hey baby!"

Jacob greeted excitedly, and he quickly looked at Nicolas Flamel beside him and asked: "Where... is this place? Is it still France?"

"Of course." Nicolas Flamel nodded: "This is the Lestrange Tomb."]

"Is this Nicolas Flamel? He looks like an ordinary old man, and he seems... very weak." Ron finally couldn't help but complain.

"I always feel that the thief should have gone directly to steal from him, instead of waiting until the Philosopher's Stone fell into the safest Hogwarts before thinking about stealing."

Listening to Ron's complaints, Harry did not discuss with him, but pointed at the screen curiously and asked

"Lestrange Tomb? What is that?"

Ron explained: "One of the Sacred Twenty-Eight Families, the tomb of the Lestrange family."

"The Sacred Twenty-Eight Families? It sounds very powerful." Harry obviously didn't know the meaning of this title.

And Ron said nonchalantly: "It refers to the 28 pure-blood wizard families. I don't know who ranked them back then, and they also included our Weasley family. God, our family obviously has many Muggle ancestors! And this is obviously cool, I don't know why those families are still proud of pure blood."

"Ignorant arrogance." Hermione gritted her teeth and said on the side.

Obviously, the name of pure blood made her very uncomfortable.

Zhang Dong on the side also nodded: "Indeed. For the so-called bloodline, these so-called pure-blood families have only intermarried within 28 families for so many years, thinking that this can maintain the honor of the pure-blood family. It's ridiculous..."

"Huh? What's so funny?" Ron didn't quite understand. Although he thought that pure blood was nothing to be proud of, it was not ridiculous.

Listening to Ron's question, Zhang Dong laughed and then said: "They must have never attended a junior high school in a Muggle school. If they have attended for a year, they should also understand one thing, that inbreeding is not a good thing."

"Huh??" Ron obviously didn't understand. Of course, they entered Hogwarts at the age of eleven, so of course they would not go to a Muggle junior high school.

Zhang Dong feltI felt that I really needed to teach them some science, so I said

"Everyone has several or even dozens of recessive alleles. Close relatives have a high degree of blood similarity, so they have similar genes."

"So once they get married, these recessive alleles will easily overlap and combine, causing the genes of their offspring to mutate, resulting in various genetic diseases, congenital malformations, physical defects, etc. Now, the so-called sacred 28 families are all intermarrying, and almost every family has a certain blood relationship. Tell me, how many healthy babies can be born in such a family."

At this point, Zhang Dong pointed to Malfoy in the Slytherin seat and then said

"If this continues, without external intervention, within a hundred years, the sacred 28 families will go to extinction on their own."
