Hogwarts: My Spell Infinite Derivation

Chapter 87 The Strongest Defensive Magic! One Million Points!

After seeing Ciel Evans' name on the Marauder's Map and entering the trapdoor at the end of the fourth-floor corridor, the Weasley twins, who had already left, frantically ran over.

It's too late to call the professor now; only they can rescue Charles immediately.

"Hopefully, it's not too late."

The Weasley twins were holding dung bombs in their hands.

This is one of the methods they came up with to deal with the three-headed dog in a short period of time.

As everyone knows, a leopard can't change its spots.

Perhaps throwing a dung bomb would change Cerberus's appetite and let Ciel go?

But just as the two of them rushed through the trapdoor, wand in one hand and dung bomb in the other, ready to rescue Ciel...

The scene that appeared before them made them pause for a moment.

Charles was not seen inside the trapdoor.

The two of them immediately felt a pang of anxiety, and simultaneously thought of the same possibility.

"Has Charles Evans already been eaten by Cerberus?"

The thought turned them pale.

But soon they realized something was wrong.

If Ciel had been eaten, there should at least have been bloodstains and torn pieces of his school uniform on the ground, but there was nothing there.

Moreover, even the three-headed dog was no longer as ferocious as before, but seemed listless, shrinking into the corner of the room, curling up, and making a whimpering sound from its mouth and nose.

Judging from her appearance, she looks like she was beaten and cried?!

Even when he saw the Weasley twins, Cerberus didn't try to pounce. Instead, he seemed quite frightened, and his massive body shrank a little.

This left the Weasley twins completely bewildered.

What's going on here?

In such a short time, the three-headed dog has completely changed its temperament?

What terrible thing happened to it?

The Weasley twins exited the trapdoor and couldn't resist pulling out the Marauder's Map again, wanting to see where Ciel Evans' name appeared.

But when they reached out, they discovered that the Marauder's Map had vanished.

The Weasley twins looked at each other in bewilderment.

"What's going on?!"

"The Marauder's Map was just in our pockets, how come it's gone now?"

"This is unbelievable!"

Before they could think any further, the voice of Filch, the school building manager, came from the stairwell.

"We've got you!"

The Weasley twins instinctively threw the dung bomb and then ran away.

During their escape, the two exchanged a glance and both had the same idea.

"Cial Evans, this first-year student is definitely not simple!"

……

Meanwhile, Shire, carrying the spoils of the night, leisurely ascended the Hogwarts stairs.

This time, the staircases were very sensible, carrying Ciel up the stairs to the Hufflepuff common room, one floor at a time.

In Ciel's hand, there was now a Marauder's Map, the very one he had obtained from the Weasley twins earlier by casting the Disillusionment Charm.

Looking at the Marauder's Map, a strange light appeared in Charles's eyes.

This thing is incredibly powerful in the original books; it can display not only the names of Dumbledore and Voldemort, but even Peter Pettigrew in his Animagus form.

It's truly unbelievable that James Potter and others could have created something like this.

This made Charles wonder.

If the technology of the liveness map could be replicated elsewhere, or if it could be expanded, wouldn't it be possible to detect all the movements of the enemy's manpower clearly?

Why haven't we seen techniques like Marauder's Maps used in the battles between the Order of the Phoenix and the Death Eaters?

The only explanation is that the Marauder's Map's uniqueness depends on Hogwarts.

James Potter and others must have used Hogwarts' own magic to create the Marauder's Map.

This is the only way to explain why the Marauder's Map can clearly show the movements of everyone in Hogwarts, because it essentially borrows Hogwarts' surveillance privileges!

Ciel tapped his wand on the Marauder's Map and uttered the oath from the original story.

Soon, names and a map of Hogwarts appeared on the parchment.

Along with this scene, a deep blue notification sounded in Charles's mind.

"The host has gained knowledge that can be deduced—Hogwarts Protection Magic (partial)."

"The initial simulation requires one million simulation points. Simulate?"

"Acquiring the legacy of the four founders of Hogwarts will significantly reduce the number of deduction points required."

Upon hearing this notification, Charles's pupils contracted slightly.

He didn't expect that his guess was actually right; the Marauder's Map really did borrow Hogwarts' protective magic.

He never expected that Hogwarts' protective magic could be deduced by Deep Blue.

Furthermore, just looking at the number of points required for this initial deduction, it is arguably the most demanding among all the knowledge that Xia Er has encountered so far!

But thinking about it, it's not surprising.

This protective magic has enveloped Hogwarts for millennia with very few breaches, and almost no external enemies have been able to break in, earning Hogwarts the title of the safest place in the wizarding world, which is enough to prove the power of this magic.

The product of the four founders' painstaking efforts is not something to be overrated.

The protective magic likely contained the four individuals' vast magical knowledge, and over the next thousand years, generations of headmasters, professors, and outstanding wizards continued to refine it.

Mastering this protective magic means having grasped the essence of so many protective spells, enabling one to independently create a place comparable to Hogwarts!

This wouldn't be an exaggeration to call it the strongest protective magic in history!

It would be abnormal if the number of deduced demand points was small.

A thought even crossed Charles's mind.

Even though Hogwarts' protective magic needs to cover the entire school, it still has such strong protective power.

If its range were reduced to concentrate its protective effect, wouldn't the area covered by the protective magic be as solid as a rock?!

Thinking of this, Charles's gaze became intense.

"Hogwarts, a thousand-year-old institution that has produced countless geniuses and wizards like Dumbledore and Voldemort, truly lives up to its reputation."

"There are just too many secrets."

"According to Deep Blue, obtaining the legacy of the four founders can significantly reduce the points needed to deduce Hogwarts' protective magic."

"But in the original work, apart from Slytherin having the concept of a 'successor,' the other houses don't seem to have a similar concept. It seems to have been lost to history and needs to be carefully searched for."

As Ciel pondered, the stairs slowly came to a stop, leading him to the entrance of the Hufflepuff common room.

Charles also gathered his thoughts and looked at the handle at the entrance to the common room.

There's no rush to figure out what the four founders have passed down; finding out won't happen overnight.

I did have a fight with the Cerberus, and I also got it neutered. It's a bit thirsty now.

According to Cedric Diggory, there seems to be a self-service magic vinegar sauce here?

The next moment, Charles grabbed the handle, looking troubled.

"Oh dear, what was the password again? I've forgotten. Look at my memory."

Then he tapped it twice casually.

Immediately afterwards, magical vinegar juice with a strong acetic acid smell gushed out from the nozzles on both sides of the door.

These nozzles also seemed to have aiming capabilities, spraying vinegar directly at Ciel's mouth.

Charles grinned at the sight.

"How thoughtful!"

Immediately, he opened his mouth and gulped down the vinegar.

In his mind, Deep Blue issued a notification.

"Deduction points +50..."

"Deduction points +50..."

After this wave of vinegar splattering subsided, Xia Er's deduction points increased by over a thousand.

This number is already quite large, not to mention that, according to Cedric, the magical vinegar that will gush out later will be even more concentrated, and may even include vinegar brewed by Hufflepuff himself.

Charles's eyes gleamed with fervor and greed as he casually knocked on the door knocker.

Without stopping, a large amount of vinegar juice gushed out.

"Again!"

"Again!"

In the end, Ciel stopped pretending altogether, too lazy to knock on the door knocker, and simply walked straight to the doorway of the Hufflepuff common room.

"I'm a bad guy, I'm going to go into Hufflepuff and do evil."

"Quick, spray out all the magical vinegar from the Hufflepuff era, or I'm going to do something bad!"

Then Charles stood with his mouth wide open, directly in front of the nozzle gushing out vinegar.

The next moment, a magical vinegar that could make ordinary people feel sour just by smelling it gushed out.

Charles, however, grinned and burst into wild laughter.

As expected of a magical product left over from the Hufflepuff era, even though it's just magical vinegar, the magic it contains is extremely concentrated.

In a short time, Xia Er's mind was filled with the constant deep blue notification sounds.

"Deduction points +1000..."

"Deduction points +1000..."

When the magical vinegar stopped gushing out, Xia Er's deduction points soared by nearly a million in that short period of time!
