Belby looked at him in confusion. Are you planning to let me go back and rebuild?

"Let's find a place to sit down and talk, how about the three brooms from Hogsmeade?" Felix suggested.

"No problem." Belby said a few words to his brother and walked over quickly.

Snape had already left, so the two of them used the phantom to move and went directly to the entrance of the Three Broom Tavern.

"A great experience, Felix, I didn't even feel uncomfortable." Belby said in admiration: "I usually don't use it if I go on my own unless I have to..."

Felix and Belby walked into the tavern. Today was the weekend. There were little wizards from Hogwarts sitting in groups of three or three, especially couples. They also watched Professor Hayp walk in with a stranger in surprise.

"Is that Professor Hepp's friend?" Cremy Villa thought to himself, and the girl next to her stared at the two of them curiously.

Felix picked a corner location, and Mrs. Rosmerta came to write down what they ordered, and in less than a minute, she sent it over.

“A glass of low alcohol honey.”

“A glass of pear with lemon wine.”

She twisted her waist and left.

Felix knocked on the table, and the sound around him suddenly became weaker.

"Felix, is this?"

"It is best not to let the little wizards know about the conversation between us." Felix pointed not far away, and the little wizards looked curiously, and he even saw a few familiar faces.

Next, Felix introduced him to his experience in taking the Black Magic Defense Class.

"So that's the case, I didn't pay much attention to this matter," said Belby.

"There is something I must remind you about the rumors that this outside class was cursed..." Felix disappeared Voldemort's existence and used a powerful wizard to refer to the source of the curse.

"Well..." Belby hesitated. "According to your words, I only need to teach a class for half a year. Can't the curse affect me?"

"From the experience of the past few decades, this is true. Most of the wizards who have taught the Dark Magic Defense Class are still alive, except for a few—"

"But they all have their own reasons, Damocles, you are a good wizard and have a shorter substitute time, and this danger is almost negligible."

Felix said sincerely: "Hogwarts has the largest collection of books in the world, and I think it will have a significant effect on you at this stage."

Belby's eyes suddenly lit up, "Indeed... I spent more than ten years studying wolf poison, and the most troublesome thing about me is the lack of similar research materials."

Potion Masters are all a group of homeless wizards, and they have less time to communicate, which is related to the nature of the potion - a potion needs to be boiled for one or two months, and if you want to make improvements, at least hundreds of experiments must be conducted.

His mind became lively and he might be able to recharge himself in half a year - the word "recharge" was also learned from the Muggle World.

What's more, there is a potion master in Hogwarts to communicate;

Plus the double temptation of Forbidden Forest and Mrs. Sprout’s greenhouse…

"If I agree to teach, do you have any suggestions, Felix?" asked Belby, who was already moved.

Felix thought for a moment and said, "I suggest you prepare a few magical defense items - I can provide them to you, no, no, there is no need to be nervous, I am just used to actively dealing with problems." He looked at Belby's expression and added.

"Secondly, when you communicate with Dumbledore, you can learn more about the course, especially those wizards who once taught the Dark Magic Defense class - how are they? You can even visit some of them."

"Finally, prepare lessons in advance, the level of the little wizards of Hogwarts may be beyond your expectations."

Belby smiled: "I also graduated from Hogwarts, Felix, I understand my level at that time."

...

On the same day, Felix told Dumbledore about this.

"So, we will soon welcome an excellent professor?" Dumbledore's face showed a surprise expression. "To be honest, I'm going to send the recruitment advertisement."

"President Dumbledore, Belby was just a little intentional, and he still needed to communicate with him in detail, so I won't participate in this regard. But - he is one of the few friends who can be chatted with, and I hope you can ensure his safety."

Dumbledore looked at Felix with his azure blue eyes, and he smiled gently and said, "Of course."

In the next few days, Felix didn't pay much attention to this matter. He went to class step by step, answered questions and studied magic.

This rhythmic life blurred the feeling of time.

The week passed quickly.

On a clear afternoon, the snow in the castle began to melt, and snow water drizzled from the eaves.

The Weasley twins blocked him when the class was over.

The two of them laughed and took out two coins, and Felix took them over. He couldn't help but suspect that they had scrapped the "Ferrogen Nat".

But to his surprise, the coins were intact and there were more things.

Felix stroked the copper Nath in his hand and looked at the twins, and they also returned with sly eyes.

"Is this going to test me?"

He felt the magic contained in it. After more than ten seconds, he pinched one of the coins and injected magic into it. The other copper Nat quickly became hot and his performance became uneven.

Felix looked carefully and saw several abbreviations appearing on this scary hot coin. He tried to think about it and found that the most consistent sentence was-

‘Felch is here, let’s go!’

Felix: "...Is this your night tour prop?"

"Uh, Professor Hayp," said Fred. "Don't you think this is a good emergency item - Aurors should be used when raiding the magic black market, such as making up for loopholes in defense."

"Or it is a couple who passes codes, and the words on them are filled out casually," said George.

hehe.

Felex would not believe it. They first developed this thing, which was definitely to facilitate night tours.

And, what magic black market... I think you are connoting me.

But - their thinking is very broad. Just like the two situations they mentioned, it really has certain feasibility.

"Then is your purpose of coming to me?" he asked.

"Professor Haipu, we encountered some difficulties - for example, the words on the coin are fixed and we cannot change them."

"The coin itself is too small to write anything."

"Yes, we hope to develop gadgets for two-way communication, similar to double-sided mirrors, of course—"

“——The cost is lower!”

“——It’s easier to make!”

They looked at Professor Happ eagerly, hoping that Professor Happ could answer their confusion.

In the past few years, some prank props have been studied by the twins themselves, but many ideas cannot be realized and can only be left behind.

Fortunately, Professor Happ promised that they could ask him for help at any time.

When the twins finished speaking, Felix fell into deep thought and stood still.

A few minutes later—
Chapter completed!
