Sherlock Holmes at Hogwarts.

Chapter 236 The truth is already obvious.

An empty classroom on the fourth floor of Hogwarts.

The four members of the Xiahahero family gathered together.

Hermione cleared her throat, glanced at her three friends, and said:
Using clues like "fifty years ago," "a special award for the school," "Slytherin prefect," and "Tom Riddle" as tags, I discovered a lot of information, which I have summarized below:

Tom Marvolo Riddle, born on December 31, 1926, is a half-blood wizard whose registered address is an orphanage…

"Oh, he's so pitiful!"

"I would rather have grown up in an orphanage."

"Shut up, both of you!"

Hermione glared at Harry and Ron with displeasure, and continued:

"In 1938, fifty-five years ago, Tom Riddle entered Hogwarts and was sorted into Slytherin House."

His performance at school was outstanding. Besides the prefectural leadership and special awards Sherlock mentioned, I found he also received a Medal for Outstanding Conduct and was listed as the student council president.

"Prefect, president of the boys' student council, and maybe even first in every subject... It's unbelievable, you know, this guy reminds me of Percy."

"Judging from the tone of your voice, it sounds like something bad has happened."

Hermione said irritably, "And Ronald, don't interrupt me anymore."

As you said, Tom Riddle, like your brother Percy, is one of the few outstanding students to have earned 12 certificates in the OWL exams—and he achieved straight A's, which is even more impressive than Percy's achievement.

No, I should say I've never heard of anyone getting top marks in every subject and making it into seventh grade. That's incredibly difficult!

Tom Riddle graduated from school in 1945, and there have been no further records of that name since.

This is rather strange, as a student of his caliber should have been admitted to the Ministry of Magic.

Even if he hadn't joined the Ministry of Magic, he would likely have made amazing achievements in other areas.

In short, he shouldn't remain so unknown.

After saying this, Hermione looked at Sherlock and found that he had been deep in thought, his hands clasped together and his chin resting on his hand.

Fortunately, Sherlock spoke up after only a short while:

"Let's talk about other things."

Hermione tried to read something from Sherlock's expression.

However, after trying, he realized that he still did not have Sherlock's meticulous observation skills, and in the end he could only shake his head regretfully and give up the idea.

She turned to the second page of her notebook and became excited again:
"Mette Warren!"

Sherlock, you're right. If Mr. Dumbledore had told us the name sooner, we could have saved ourselves a lot of trouble.

Because Maitl Warren's full name was Maitl Elizabeth Warren, and in 1943, fifty years ago, she was a Ravenclaw student.

After saying that, she looked at Harry.

Harry felt a little awkward under Hermione's expectant gaze, and he said somewhat uneasily:
"Hermione, the way you're looking at me is as if I should know this girl."

“Harry, you do know her—not only that, you’ve met her,” Hermione said smugly.

"what?!"

Harry and Ron were stunned when they heard Hermione's words.

"Me? I met the students who were killed fifty years ago? How is that possible? Unless... unless..."

Harry pondered for a long time, but still couldn't come up with a suitable reason.

"Unless she becomes a ghost."

Sherlock said quietly.

"Oh, don't do that, Sherlock, I wanted to scare them!"

Hermione said somewhat disgruntledly, "It's their fault for always interrupting me."

Reminded by Sherlock, Harry immediately realized what was happening.

Aside from Nick, who was almost headless, and Peeves, the only ghost he could claim to have had a deep conversation with was at the anniversary party.

"Hermione, are you talking about... Moaning Myrtle!"

"Bingo!"

Hermione snapped her fingers:
"Moaning Myrtle is Myrtle Warren fifty years ago!"

If I had known earlier that she was the one who was murdered fifty years ago, I would have gone straight to her and confronted her about the killer!
It might take a while, you know, she has a bad temper.

At this point, Hermione laughed again: "But it's no longer needed now."

"why?"

Harry and Ron asked anxiously.

Hermione glanced at Sherlock. "Because the truth is already obvious."

As she spoke, she turned to the third page of her notebook.

"The Basilisk is a giant venomous snake, also known as the King of Serpents."

It is a magically bred creature, ranking at the highest level in the Department of Magic's classification system, on par with the eight-eyed giant spider kept by Hagrid.

After Hermione finished speaking, seeing that Harry and Ron seemed not to have reacted yet, she simply read another sentence:

"Many terrible beasts and monsters roam our country, among which the most bizarre and deadly are the basilisk monsters."

It was hatched by a toad from a male egg.

"Rooster eggs? Do you mean eggs laid by hens that have undergone sex reversal and become roosters?"

"Gender reversal?"

Hermione paused, taken aback. Clearly, Sherlock's words had touched on a blind spot in her knowledge.

"Yes, sex reversal is when a functional male or female individual transforms into an individual of the opposite sex."

For example, when a flock of chickens has no rooster, the strongest hen will gradually change sex and become a rooster.

Harry, Hermione, and Ron were stunned.

A hen turned into a rooster?

This is just too outrageous!
Ron couldn't help but ask, "Sherlock, is this... is this knowledge from the magical world or the Muggle world?"

"That's common sense, my friend."

"..."

I didn't need to ask that question!
Only Hermione hesitated for a moment, then nodded:
"Perhaps...you're right."

The first recorded basilisk was bred by the 'despicable Halbo'.

He was a Greek sorcerer who spoke Parsleyan, and one of the earliest known sorcerers.

To this day, much of his research continues to influence black magic.

After numerous experiments, this person discovered that if a male egg is placed under the body of a toad for incubation, a dangerous snake with extraordinary abilities will hatch from it.

His rooster eggs were most likely obtained through the 'sex reversal' method you just mentioned.

"Sorry to interrupt you, please continue."

"Yes, Sherlock."

Looking at Hermione's amiable expression, Harry and Ron exchanged a helpless glance.

Sherlock can interrupt, but we can't, right?

"The basilisk is enormous, growing up to 50 feet long, with dark green skin and a pair of yellow eyes."

Its skin scales have strong magic resistance and can deflect spells.

Like other snakes, the basilisk sheds its skin periodically as it grows.

The danger of the basilisk lies in its venom, a highly toxic substance that can kill a person in minutes.

Even five years after the basilisk itself died, its venom could still be used to destroy inanimate objects, rendering them irreparable.

However, compared to its enormous body, magic-resistant skin, and almost incurable venom, the basilisk's most terrifying feature is its eyes.

Hermione paused here, then continued:

"The basilisk's eyes can kill any person or animal that makes eye contact with it in an instant—anyone who is stared at by its gaze will die immediately."

Spiders are terrified of this creature, regarding it as a mortal enemy, and even refuse to utter its name.

Meanwhile, the basilisk would flee in terror at the mere sound of a rooster crowing, for the rooster's crow was also deadly to it.

As soon as Hermione finished speaking, Ron jumped up: "I get it! The monster in the Chamber of Secrets is the Basilisk!"

He gripped Harry's arm tightly and said excitedly:
"No wonder only you can hear its voice, because you are a snake-talker!"

Hagrid's eight-eyed giant spider was afraid to reveal its name because the basilisk was the spider's natural enemy.

All the roosters in the school are dead because someone didn't want the basilisk to hear their cries!

Compared to the excited Ron, Harry seemed much calmer, looking at Sherlock with curiosity:
"No wonder you asked me before if I had found the spider. So you already knew back then?"

"Actually, I had my suspicions much earlier."

"Even earlier? When?"

“Christmas,” Sherlock said calmly, “was inspired by Mycroft.”

"Yes, I was right there at the time."

Hearing this, Hermione, who was standing nearby, proudly puffed out her little chest.

After Ron's excitement subsided, he couldn't help but ask again:

"But how could a basilisk monster crawl around attacking people? It's 50 feet long, it's impossible for it not to be noticed!"

"tube."

"tube?"

Ron didn't react for a moment.

Harry then understood: "That's why I always hear that sound in the wall because it's always moving inside the tube!"
"You even thought of that? Hermione, you're amazing!"

Hermione glanced at Sherlock somewhat sheepishly:
"It was all thanks to Sherlock pointing me in the right direction that I was able to follow the clues. Before that, I was completely clueless."

"Don't underestimate yourself, my dear Hermione."

Sherlock said calmly, "At least I didn't tell you about the pipes; you found out on your own."

"Thank you so much for your comforting words!"

Hermione said grumpily.

Sherlock is like a teacher who has given you a problem and even calculated up to the penultimate step. Now he only asks you to write out the final calculation process and result.

Now that the monster in the Chamber of Secrets has been confirmed to be the Basilisk, and given that the sounds Harry hears always originate from inside the walls, if he still can't figure out the tube, he might as well be dead.

Wait, just a minute!
Hermione suddenly looked at Ron.

She suddenly realized that Sherlock was right.

Not everyone can think of this without being reminded by others.

Ron: (ー`ー)
