Ever since that time for Sir Nicholas, Ricardo had been blessed with ghostly conveniences, and all the castle ghosts were very friendly to him, always smiling when they saw him.

Of course, the friendliest of them all was, of course, Sir Nicholas, who not only offered to tell him a lot of secrets about the soul, but was also willing to volunteer for him.

This couldn't be better: research requires enough research data, and experiments with Voldemort did speed up his research process, but he is now a remnant soul, and the spell is to be applied to people, so it is naturally better to have a complete soul body to study.

However, Sir Nicholas's ghost is still more than a little worse, much weaker than the remnant of the Falling Ground Demon - perhaps he should not be compared to Voldemort, after all, Old Man Tom is also a big man who has won the title of Dark Lord, and his soul strength is no better than that of mortals.

Ricardo couldn't use too powerful spells and couldn't inject too much magic, but he also gained a lot of insights and a deeper understanding of the soul.

As for the previous incident, Ricardo also did a lot of research.

It must have been snakes that came and went freely, and then the shadows he saw were definitely humans, and the shadows somehow cut off his ability to perceive his surroundings, miraculously breaking through Hogwarts' anti-illusion magic, perhaps a teleportation rather than a phantom shifter, and left there.

Cutting off the perception doesn't mean anything, after all, it only caused a moment of trouble, and it also made him figure out the other party's path. The next time he hits, he can even fight back and directly make the other party faint.

As for why it feels familiar, I want to cry when I feel familiar...... Probably a kind of innate magic, the blood clan has this power of emotional guidance, which can interfere with the judgment of the other party. Alas, when it comes to the innate magic of the Blood Clan, he seems to have felt it from somewhere......

As for the snake...... Ricardo vaguely felt that it was not simple.

"Sir, do you know any legends about snakes in Hogwarts?"

Sir Nicholas bowed his head and thought hard for a long time.

"I think...... The only one who has to do with snakes is Lord Salazar Slytherin, right? ”

"Legends related to Lord Slytherin...... And what are they? ”

"That's the Chamber of Secrets." Sir Nicholas said slowly.

"The ????!!!!! of the Chamber of Secrets"

Ricardo was stunned, really stunned.

Chamber...... Harry Potter and the Chamber of Secrets......

What did I do before!!!

What else is the secret room in Harry Potter's heart...... Oh my god, what the hell do I want to do!!!

It's good that I didn't say it! It would be embarrassing if someone else knew about it!

Facts have proved that a secret room is a secret room, and there are many metaphors in children's literature, and you can't use the thinking brain of online texts!!!

"So, what's the story of the Chamber of Secrets?"

After calming down his embarrassment, Ricardo asked again.

"I only heard Professor Binns mention that thing once fifty years ago," Sir Nicholas was a little cramped, "and he kept telling us that it was just myths and legends, and that it wasn't worth listening to at all......"

"I'd like to ask, Sir, legends have a certain factual basis, don't they?"

"Oh, well, then," he sighed, and said slowly, "let me think about it...... Secret Room ......"

"As you surely know, Hogwarts School was founded more than a thousand years ago, and the exact date is uncertain - the founders were four of the greatest witches and wizards of the time. Four houses are named after them: Godric Gryffindor, Helga Hufflepuff, Rowena Ravenclaw, and Salazar Slytherin. ”

"Together, they built the castle away from the prying eyes of Muggles, because at that time, the common people were afraid of magic, and witches and witches were persecuted."

Sir Nicholas paused, looked around the office with a blurred vision, and continued: "In the first few years, several founders worked together in harmony, looking for young men who showed signs of magic, and brought them to the castle to be cultivated. Slowly, however, a disagreement began between them. ”

"The rift between Slytherin and the others is growing. Slytherin wanted Hogwarts to be more selective when it came to recruiting students. He believed that magical education should be confined to purely magical families. He was reluctant to accept Muggle-born children, believing them to be unreliable. After a few days, Slytherin and Gryffindor had a heated argument over the issue, and Slytherin left the school. ”

"Reliable historical sources tell us this," he said, "but these pure facts are obscured by strange legends about the secret chambers." The story goes that Slytherin built a secret room in the castle that the other founders knew nothing about. ”

According to this legend, Slytherin sealed the Chamber of Secrets so that no one could open it until his true heir came to the school. Only the heir can open the Chamber of Secrets, release the horrors inside, and let it purify the school and rid it of all those who don't deserve to learn magic. ”

"Of course, the whole thing is nonsense," he said, "and the school has naturally investigated whether there is such a secret room, and has investigated many times, and has invited the most learned witches and wizards. The Chamber of Secrets does not exist. It's just a story designed to scare simple-minded people. ”

"Sir Nicholas, what do you think you mean when you say 'the horror stuff inside' in the Chamber of Secrets?"

"It is believed to be some kind of monster that only the heirs of Slytherin can control." Sir Nicholas said in his dry, thin voice.

"What could it be? A snake? ”

"Enough, Professor Silva," Sir Nicholas said in a loud voice, pleading, "it's a myth! It doesn't exist at all! There is not the slightest evidence that Slytherin ever built such a secret broomstick shed or anything like that. I am so sorry to tell you this ridiculous story, you have been in enough danger that I can't imagine your future! ”

"Well," Ricardo nodded, ostensibly agreeing, "hard work, Sir, I'm not going to study him." ”

"That's good, that's good......" Sir Nicholas muttered to himself, breathing a sigh of relief, "I've told you too much, even if fate doesn't cast its eyes on this haze now, but it will see it then, and then ......"

What he didn't see was that Ricardo sat down at the table and opened a notebook.

"Mentor, do you know the legend of the Chamber of Secrets?"
