Harry Potter: From Muggle Cousin to Conceptual Archmage

"I've read the works of genetic biologist Gregor Mendel. Inbreeding can lead to genetic mutations and physical deformities in offspring. Only a low probability will result in individuals with extremely high intelligence and inborn endowments. But in the long run, if inter - marriage between close relatives continues for generations, it will surely increase the rates of deformity and infant mortality among a family's descendants, and eventually lead to the family's complete extinction."

Hermione fully showed the charm of the "know - it - all girl" and gave a lesson to her peers in the wizarding world.

"That's right!"

Dudley gave an admiring look to Hermione and added, "So, pure - blood wizard Malfoy, do you understand? The wizarding bloodline, similar to Muggle genes, requires diversity and richness.

If wizards never intermarry with Muggles, there won't be any Muggle - born wizards. Meanwhile, wizards will become an endangered species.

To date, there is no such thing as absolute pure - blood in this world. Every wizard, including you, Malfoy, has more or less Muggle blood. That's a fact!"

Dudley's words were like swords and spears, directly piercing through Malfoy's young defense.

But actually, there was a slight oversight in what Dudley said just now.

That is, there is actually a real pure - blood wizard in this world, and that's Dudley himself.

Because his wizarding bloodline was obtained by fusing the The Philosopher's Stone. Just like the first group of pure - blood wizards, their wizarding bloodlines were definitely not inborn. It's highly likely that they accidentally obtained it from magical creatures.

The evidence for this view is obvious. Wizards are humans, and Muggles are also humans. They are the same species biologically. Why do wizards have magic while Muggles don't?

The most likely explanation is that the original wizards were also Muggles.

They were the outstanding or lucky ones among humans. They obtained some kind of magical substance or power from the naturally - existing magical creatures or magical materials in this world and transformed themselves into wizards.

After that, through continuous reproduction and intermarriage with others, they spread the wizarding bloodline.

To date, perhaps every Muggle's genes contain magic power genes.

However, the magic power gene is a recessive gene, while the non - magic gene is a dominant gene. Muggles have both non - magic genes and magic power genes, and the trait expressed is the dominant trait corresponding to the non - magic gene, that is, having no magic power, being unable to perform magic, and unable to become a wizard.

This is also the reason why two Muggles can have a wizard child.

The children inherit the magic power genes from both Muggles. Having only magic power genes and no non - magic genes, they exhibit the recessive trait corresponding to the magic power gene, namely, having magic power, being able to perform magic, and becoming a wizard.

"I don't believe it!"

After listening to Dudley's conclusion, Malfoy erupted again.

His worldview and values were greatly impacted, and he instinctively began to reject and deny what Dudley said. "I'm pure - blood! The Malfoy family is pure - blood, and all the Twenty - Eight Sacred Families are pure - blood! You... You two Mudbloods are talking rubbish!

I won't believe you! I won't believe you..."

Looking at Malfoy's nearly crazy look, Dudley lost interest in continuing the debate.

His goal had been achieved. Hermione had already understood what the so - called pure - blood meant. Now, when she heard Malfoy call her a 'Mudblood', she could remain calm, just regarding it as the howl of a madman.

Dudley was also eligible to claim the System reward for resolving the 'b - level regret event - The Bullied Know - It - All Girl'. However, he didn't claim it for the time being because he hadn't achieved a perfect resolution, and thus couldn't get the maximum reward.

It's likely that Hermione will need to handle a few more cases of bloodline discrimination and bullying independently during her future studies at Hogwarts to completely solidify the newly - formed perception.

As for Malfoy, Dudley believed that the words he had just said must have left an indelible impression on Malfoy, shattering many cracks in his perception of pure - blood.

Perhaps before long, this young Master Malfoy, who still had a bit of goodness in his heart, would gradually accept this point.

Thinking of this, Dudley was about to cast a little magic on the Malfoy Trio to let Malfoy remember this lesson.

Unexpectedly, Ron, who was sitting opposite him, spoke up.

Both the Weasley and Longbottom families are among the so - called Twenty - Eight Sacred Families.

However, the Weasley family doesn't believe in the so - called 'pure - blood supremacy'.

"Malfoy, if you can't figure it out yourself, don't drag us into it!" Ron sneered at Malfoy and said, "Our Weasley family is also one of the Twenty - Eight Sacred Families, but there must have been intermarriages with Muggles in our family!"

"Only you stubborn pure - blood families dare not admit all this!"

"So your Weasley family is the disgrace of pure - bloods!"

How could Malfoy tolerate the Weasleys, whom his family looked down upon, talking back to him? No longer in a daze, he immediately retorted.

Ron's face flushed with anger again. In order not to lose face in front of his newly - made friends and for the honor of his family, he didn't even think before exposing the Malfoy family's old secrets:

"Your Malfoy family are the shameless ones who act one way and talk another!

Don't think I'm ignorant. Your Malfoy family tree may seem to have only wizards' names on every branch. But in fact, every one or two generations, your family marries a half - blood wizard to improve the family genes, as Dudley and Hermione just said.

Also, it's spread all over the pure - blood family circle that Lucius I, the ancestor of your Malfoy family, once courted a Muggle queen but failed!

With all this, do you still have the nerve to claim to be pure - blood? And dare to insult and bully others in the name of pure - blood supremacy? I'm ashamed of you!"

"You... you... you guys... Ugh—"

The family gossip exposed by Ron became the last straw that broke Malfoy's back. Malfoy was mentally and physically exhausted and couldn't bear the successive blows. With a grunt, he fainted from anger.

Everyone else in the compartment looked at Ron. Ron said in a panic, "It's not my fault! Malfoy is just useless!"

Dudley gave Ron a thumbs - up, which made Ron feel a little more at ease. Then he pointed at the Malfoy Trio.

Obliviate!

A dazzling white light enveloped Crabbe and Goyle, causing these two hopelessly stupid kids, who hadn't listened to a single word from start to finish, to forget everything that had occurred in the compartment. All they knew was that they three had been dragged into the compartment by Dudley and thrashed.

"Transfigure quickly! Permanent Spell!"

After that, the powerful light of transfiguration engulfed the robes worn by the Malfoy Trio. The robes of the three were transformed into mud - covered robes, making them all covered in sticky, stinky, and filthy mud, as if they were wearing the rotten black mud from the swamp.

Moreover, Dudley made the transformation effect permanent so that it would last long, and the Malfoy Trio couldn't even take off their clothes.

"Ugh—"

"Pfft—"

Dudley lifted the [Silencing Charm] on Crabbe and Goyle. Feeling the sticky, dirty, and smelly mud on their bodies, they vomited disgustingly, adding even more filth to their mud - covered robes.

"If you use the word 'Mudblood' to insult others, you should be ready to turn into mud!"

Dudley said assertively, waved his wand, and cast the Bubble - Head Charm, creating a big bubble to shield himself and his mates, isolating the unpleasant smell. Then he lifted the locking [magic] on the compartment door and opened it remotely.

"Get out of here with your Boss!"

Dudley tossed the [wands] of the Malfoy Trio into the outer corridor and shouted angrily.
