The award ceremony went smoothly, and there was nothing "worrying". Felix felt that Professor Trelawney had made a mistake again, but it was hard to say, as he could not go into the prophecy hall of the Department of Mysteries to see if any new prophecies had been formed.

The Department of Mysteries is located on the ninth floor of the Ministry of Magic. It is a department of the Ministry of Magic that conducts secret research on specific puzzles. Most of its business is top secret, and even the staff of other departments of the Ministry of Magic are very secretive about it.

The wizards working in the Department of Mysteries are called the Unspoken. These people are forbidden to reveal any details about the content and location of their work. Felix speculated that they may have signed a harsh confidentiality agreement. While being allowed to conduct dangerous research, they are also subject to more restrictions.

However, there are rumors that there is a mysterious room in the Department of Mysteries, and for every prophecy that appears in the world, a prophecy ball will automatically appear here. Since the establishment of the Ministry of Magic, there may be thousands of prophecies that have been recorded and are waiting for verification by future generations.

...

Felix was playing with a gold medal with a purple ribbon on it, which was used to recognize his personal "outstanding achievements and efforts". Belby told him that the first-class medal was equipped with a green ribbon, representing Slytherin College.

"Isn't Merlin a medieval person? How can he be related to Slytherin College?" Felix asked curiously.

"Heh, when some pure-blood families traced their genealogy, they claimed that their ancestors had followed Merlin..."

"Is it true or not?"

"Who knows! But some families do have a long history."

Felix returned to the office. The next two weeks of Easter vacation were coming, and he could sort out his recent work. But the first thing to deal with was the Easter eggs that filled half of the room. He suddenly felt a little bit sour. These chocolate candies could keep him eating for ten years.

He picked some to give to Sirius, and gave him the results of the recent analysis of the Marauder's Map.

It was a very simple map, only the size of a palm, and the shape was irregular, like the result of a child's graffiti, with simple markings of the castle, the forbidden forest, the black lake and Hagrid's hut.

Sirius took it with a look of disdain. There were dense dots on it, which made people dizzy. However, some names were marked in small golden letters. They were the people Sirius cared about, Harry Potter, Remus Lupin, Severus Snape, Albus Dumbledore...

"Actually, there is also Peter Pettigrew, but you can't see it."

Sirius tore open the wrapping paper of an Easter chocolate egg with his teeth and took a big bite of the chocolate on it. "Thank you, otherwise I would go crazy." He kept staring at the palm-sized piece of paper.

Kreacher said in a low voice: "The prodigal son goes to the Muggle community to play chess every day and brings back a stinking body..."

"Shut up, Kreacher." Sirius roared in anger.

Days passed, and Felix took the time to reorganize the magic items he had studied this year and put the research materials into the thinking hut.

Mundungus went to the Far East as planned and brought back a large number of magic items, and Felix had only one request: ancient.

As his knowledge became richer, he felt that he was a bit like Flitwick when he was young. He had mastered too many runes, but only a small part of them could be used.

"This is also the original intention of my plan to write a book of runes."

Felix thought to himself. As his thoughts moved, magic symbols appeared in the air one after another, gold, red, blue, green... like a colorful river, flowing in the office.

"Next is the nameless book. Ha, I remember Ron Weasley called it the ghost book. It really is similar."

In front of Felix, a half-real and half-virtual book appeared. The first few pages were real entities, and the rest were all illusory. It was very similar to the nameless book in Harry's hand, but the two were not comparable.

He turned a new page, and one magic rune after another flew out of the colorful river, jumping into the pages of the book. Various magic runes appeared on the pages,

a falling waterfall, lightning that cut through the sky, a bridge connecting the two places, and green mist that continued to spread...

Felix looked at all this with satisfaction. If he included all the magic runes, it would mean that he had completely mastered the magical symbols of these magic runes, although this process might take a long time.

He suddenly thought of a question, where did the original ancient magic come from? Are

wizards born with it? It's a bit unrealistic. He tends to think that the ancient wizards accidentally triggered this inspiration when studying magical animals and plants. The

difference between the two is that for magical creatures, talent is an instinct that does not need to be learned, just like people can run and jump. They are born to release lightning and change their shapes, but inevitably, they will also be restricted by the body.

After the ancient wizards transformed their talent into ancient magic, they accidentally got rid of this confinement. Their problem is to exhaust their minds to control it so that it doesn't get out of control, but from another perspective, they also make this magic more powerful.

Felix's heart moved, and he took out a stack of parchments. These were the manuscripts left by Slytherin. He had decided to seal these materials because Salazar Slytherin's methods were too cruel and not suitable for his magic rune path, but now it seems that the two have intersected.

Unconsciously, he has been able to use his own path to analyze other people's paths.

Felix skipped those bloody and cruel methods, looking at the records of magical creatures one by one, especially the three parchments he had picked out before and thought were suitable for him. They recorded an idea of ​​Slytherin's early research on blood magic: how to strip the talents of magical creatures and transform them into spells used by wizards.

This seems to coincide with Felix's conjecture. Salazar Slytherin once thought of retracing the path of ancient wizards and getting inspiration from the wider magical world.

But unfortunately, he finally gave up this idea.

Felix couldn't help but wonder, if Salazar Slytherin chose to give up, what was he pursuing? Considering what Helena had told him, that the deeper Salazar Slytherin went into the forbidden realm, the more terrifying his appearance became, which seemed to imply that Slytherin had experimented on himself and had integrated the blood of magical creatures, and most likely more than one. Did

Salazar Slytherin become completely inhuman in the end?

The words of Ms. Rowena Ravenclaw were still ringing in his ears, "We ourselves can be considered magical creatures."

What can be considered a magical creature? Or to put it another way, when a wizard is called a magical creature, what kind of changes will he undergo? Felix had no way of knowing, but he thought that since Ms. Ravenclaw told him so solemnly, it meant that this was a huge threshold.

And it is very likely that Salazar Slytherin relied on blood transplantation to cross this threshold. What about the other three people, what did they rely on?

So far, he only knew something about Rowena Ravenclaw. Judging from the manuscripts she left behind, she was a true all-rounder. She was proficient in alchemy, transfiguration, spells, and potions, but she had studied memory magic the most.

As Felix delved deeper into the field of memory magic, he had a question: Was Rowena Ravenclaw, whom he met in the Room of Requirement, really just a memory?

Or was that her?

What will the memory node develop into in the end? Is it related to the soul?

He has too many questions, but no one can answer these questions for him, so he can only go on alone.

On the last day of the Halloween holiday, Felix gathered his mood again and prepared to face the last period of this school year, but Dumbledore suddenly appeared with a serious expression and brought him bad news.

"Nick is leaving, and he wants to see you for the last time."
