At this time, Filch, who was standing in front of him, was no longer the dirty and sloppy appearance he had before, but had become clean and tidy.

Although his demeanor still has the same shadow as before, he no longer looks like a weirdo.

It seems that Rhine's approach seems to have changed Filch.

However, Filch brought Professor McGonagall with him, which caught Rhine off guard.

"Nice to meet you, Professor McGonagall. I beg your pardon for the simplicity of the shop, but I should be able to meet what you need here. ”

Rhein greeted Professor McGonagall very warmly, and then did not forget Filch on the side.

"Mr. Filch, your change has surprised me, I almost didn't recognize it just now."

When Filch heard this, he immediately straightened his chest, trying to make himself look more energetic.

"Long time no see, Mr. Embers, I think you probably guessed what I was here for." Minerva McGonagall came to the counter.

She is a very senior professor and is used to being serious in front of students, so she is still unsmiling.

Rhine, who had just graduated, was actually in awe of Professor McGonagall.

In Hogwarts, Rhine respected Dumbledore the most, followed by Professor McGonagall in front of him.

"Of course, Professor McGonagall, I've got a brand new magic gun ready."

As he spoke, Rhine took out a delicately shaped gray magic gun from under the counter and placed it on the counter.

Professor McGonagall carefully picked it up, then looked up at Rhein, puzzled, "Mr. Embers, I would like to know how this invention of yours is able to unleash magic?" ”

"I tried it last night, and it doesn't even require mana and spells, it's incredible."

Rhein smiled and turned to look at Harry in the corner.

Harry suddenly understood, and he walked over and handed McGonagall the "textbook" in his hand.

It was only then that Professor McGonagall discovered that Harry was there, and she couldn't help but be a little surprised.

"Harry? Why are you here, this is Tumbledown Alley, not a place for underage wizards. ”

McGonagall took the notebook, but didn't immediately open it, but looked at Rhine with a questioning expression, waiting for Rhine's explanation.

Rhein explained to McGonagall, "Professor McGonagall, Harry is learning with me about magical technology, the basics of my new invention. The notebook in your hand is part of the textbook I wrote for Harry. ”

McGonagall didn't expect that Rhine had just made a new invention and would start teaching students.

She didn't say anything, but opened her notebook to see what kind of secret Rhine's new invention hid in.

At this glance, McGonagall was stunned.

She read it word by word, and the more she looked, the more frightened she became, the theory in this notebook could be said to be a completely self-created magic science.

McGonagall watched intriguedly, and Filch behind her was like a hundred claws scratching her heart, and she was so anxious that she spun in place.

In Filch's opinion, after McGonagall came here, she only needed to pay for the goods with Rhein, and the transaction process would not take a few minutes.

Filch would then be given a chance to buy enough ammo.

But Professor McGonagall didn't play the cards at all, and after watching it for an hour, there was still no sign of paying for it.

Not only Filch, but also Rhein and Harry were waiting, and no one bothered them.

"It's a miracle, Mr. Rhine, you've done a miracle......" Professor McGonagall finally came to her senses.

Her eyes lit up, and through Harry and the textbook, McGonagall had an idea.

But before she could put the idea into practice, she had to run a trial.

"With all due respect, Mr. Embers, I would like to experience the power of magical technology for myself. Can we have a friendly exchange? It's up to you to use the magic gun, and I'm the wand. ”

Hearing what McGonagall said, Rhein immediately understood.

Professor McGonagall, is this a desire to see the true power of magical technology and decide whether to recommend herself to return to Hogwarts as a teacher?

The advent of magical technology is likely to be a turning point in history. And Hogwarts is the best stage to carry it.

And Rhine himself, in fact, has always had the desire to go to Hogwarts.

With Lucius, Rhine couldn't sleep.

Now, Lucius would think that Rhine was at the mercy of Voldemort's diary, and that time was running out.

Therefore, it is probably not possible to make another move in the short term.

But what about the future?

It's not the same when you enter Hogwarts, which is known to be the safest place to be.

At least it's safer than other places and suitable for your own development.

Therefore, this opportunity, Rhine wants to fight.

"Professor McGonagall, I think there's a good place for us to have a fight."

Rhine took the magic gun from the counter and hung it on his left waist, and took out another one to hang on his right waist.

Also, I brought some magazines.

Then, with Professor McGonagall, Filch, and Harry, they walked out of the Enbers Magic Shop.

Follow Tumbling Alley until you go east, and after four turns, you come to the edge of Tumbledown Alley.

It was a small forest, and within a hundred meters of it, there was a clearing.

This forest is usually a place for shamans to hunt and gather.

Of course, the deeper you go, the more chances you have of encountering rare goodies.

And Professors Rhein and McGonagall are just for the sake of learning today, and they don't need to go deeper.

Harry was excited to see Rhein and Professor McGonagall saluting each other, bowing, and then turning away together.

Although the theory of the magic gun was magical, he had never seen Rhine use it with all his might.

So, knowing that he was about to see a showdown between magic and wand, Harry's excitement was inevitable.

The Rheinland prepared a total of eight magazines.

The magazines of the magic guns can only hold two magic bullets each, so Rhine can use sixteen magic shots.

Among them, what magic to use to crack the opponent's magic, and how to fight back, is a huge test.

"Professor McGonagall, then I'll strike first, so be careful."

"No problem, I hope your magic will surprise me even more, Mr. Embers."

As soon as the two finished speaking, Rhine instantly moved.

With his right hand touching his waist, he pulled out the magic gun, and raised his hand to pull the trigger.

Swish!

A green light shot out from the muzzle of the gun.

The first is the Disarming Charm, which is a very classic and practical "Remove Your Weapon".

With the advantage that the magic gun does not need to be chanted, Rhine tries to solve the battle in the shortest possible time.

Without chanting, the other party doesn't know what kind of magic he is unleashing.

Levitation Charm? Transfiguration Charm? Or is it a requisitioning spell? Who knows.

If it's an inexperienced wizard, I'm afraid it will be quite uncomfortable and tired to deal with.

Professor McGonagall, on the other hand, waved her wand as soon as she could, the incantation in her mouth was fast.
