Lunch consisted of lamb chops and potatoes, and Jon devoured them quickly.

After eating, he went to the Room of Requirement and sorted out the things left there......

As a stronghold, the Room of Requirement doesn't have much time left, after all, it will become lively when Dumbledore's Army (DA) is formed.

But now I don't have the same eagerness to learn spells or make potions as I did a few years ago.

So Jon wasn't worried about anything.

......

The bell rang for the afternoon class, and Jon made his way to the Charms classroom on the fourth floor.

Professor Flitwick, the little man in Charms class, sat on a large pile of cushions, welcoming everyone.

"Christopher Patrick?" he shouted in a shrill voice, glancing in Jon's direction.

"Yes, Professor!" Jon quickly stood up and nodded to him.

"Welcome...... Welcome to Hogwarts!" Flitwick jumped off the cushion and walked over to Jon and shook his hand.

Then he started the lesson, which was about the "Flying Spell"!

Professor Flitwick first spent ten minutes describing the importance of the Flying Charm...... And tell them that this is the exam in two years, and the key assessment content over the years.

"Last year, there was a brilliant Hogwarts student who used this spell to defeat a Ukrainian iron-bellied dragon in the Triwizard Tournament!" Professor Flitwick's voice choked as he spoke.

Rubbing his nose vigorously, he continued to teach the Flying Charm.

Each student was given a feather and asked to try to summon it to their hand with a "flying charm".

"The Flying Spell is probably the most complicated spell you've ever seen, so don't be discouraged or impatient if you fail," Professor Flitwick said as he walked through ......the crowd.

"Whew......" he let out a strange cry.

Then he quickly ran to Jon again, and Professor Flitwick looked him up and down.

The feather on Jon's desk was firmly in his hand.

"Well done, Mr. Patrick!" he clapped enthusiastically, "Slytherin plus ten!"

Jon had mastered the Flying Charm a year ago, and there could be no problem now...... At the same time, this operation also attracted the surprised eyes of the Slytherin and Hufflepuff students.

......

Until the end of class, there was no second student in the class who controlled the "Flying Curse".

The other students had already packed up their things and left the classroom, but Jon deliberately stayed at the back.

"What's the matter, Patrick?" Professor Flitwick said, carrying a large stack of books, as he looked at Jon.

"That's right, Professor!" Jon quickly walked over to Professor Flitwick and bent down.

"One of my relatives left me a relic but I don't know how to open it...... So, can you help me take a look?" Jon said as he pulled the small silver box out of his pocket.

This octahedron obtained from Durmstrang was spent more than two months in Jon without a clue.

In this case, he had to consult the experts...... Professor Flitsch was a good looker, but he was a good teacher of charms, and Jon could safely ask him for help.

Flitwick carefully took the silver octahedron in his hand, sniffed vigorously, and then frowned.

He then took out a magnifying glass from his pocket and carefully examined the eight sides of the small box.

Finally, he took out his wand and waved it at the small box, muttering words to his mouth.

"If I'm not mistaken......" Flitwick said with a serious face, "this should be a core of Mithera!"

"The core of Mythera?" Jon repeated the unfamiliar term, somewhat confused.

"It's a very powerful magic item, I've only heard of it, and it seems that the relative who left it to you is a very powerful wizard!" Professor Flitwick sighed.

"And what does it do?" Jon asked quickly.

"Honestly, I don't know!" Professor Flitwick shook his head, "The function of the core of Mithera is strictly secret...... It needs a key to open, and once it comes into contact with the key, it will manifest its true function. ”

"And what will be the key to it?" Jon continued.

"It's up to your relative, only the creator will know the key to the core of Mithera!" Professor Flitwick smiled, "So, Mr. Patrick, you should check if he left any wills or anything like that......"

“...... Also, the key to the Mithra's Core is related to its function, so you can check out what the creator used to do with it!" Professor Flitwick added.

"Okay, thank you for your help, Professor Flitwick!" Jon said, bowing.

"You're welcome!" Professor Flitwick nodded with a smile as he watched Jon leave.

......

The well-informed Professor Firius Flitwick did Jon a great favor.

However, finding the key to the core of Mythera is also a big problem.

All afternoon and evening, Jon experimented: fire, water, and sugar...... These common things, Jon touched them one by one to this core of Mythera.

However, there was no reaction, and the box was not opened.

By the dead of night, the three roommates had fallen asleep.

Jon, lying on the bed, picked up the small octahedral box with some boredom.

Since this thing is related to Grindelwald, it means that its key should also be related to Grindelwald.

Jon hurriedly searched his mind for memories related to Grindelwald.

Suddenly, he had an idea......

Then he got up, took his wand, and aimed it at his temple:

"Obliviate!"

A milky white substance, somewhere between gas and solid, appeared at the end of Jon's wand.

Jon carefully used his wand to guide it to the core of Mythera.

Suddenly, the small box opened suddenly...... All those milky white things have been absorbed by the core of Mithera!

Then, the tiny octahedron emitted an astonishingly intense light in all directions, almost more dazzling than the sun's rays!

The carp on the ceiling were so frightened that they fled in a hurry.

Sean Avery also seemed to be awakened: "What's going on?"

"Nothing!" Jon said, "Are you having a nightmare?"

As he spoke, he smiled as he put the small box back closed and put it back in his pocket.
