With a funny look on his face, Hagrid began to wink his eyebrows, like an adult debunking a child's prank.

Rhine smiled for a moment, then shook his head helplessly, and began to think about the effectiveness of Hagrid's science magic gun.

……

"You don't need a spell, you don't need mana, you can cast magic?"

After listening to Rhine's popular science, Hagrid was really attracted by the effect of the magic gun.

He picked up the magic gun on the counter and looked left and right, unable to believe what Rhine said.

"How is it possible to cast magic without mana? Oh! Embers, I didn't say you were a liar, I meant ...... This thing is unbelievable. ”

With a skeptical look on his face, Hagrid put the magic gun back on the counter.

It's no wonder that Hagrid reacted this way, because anyone who has studied magic knows that magic is made up of mana and spells.

Among them, the most important is mana.

Without mana, isn't it a Muggle, and has anyone ever seen a Muggle release magic?

This is the foundation of magic, the foundation of magic. So anyone who hears this kind of thing will think it's ridiculous.

Rhein smiled: "Hagrid, this is really incredible, I think you should experience it for yourself." ”

He took out one of the magic bullets he had just made and put it on the magic gun.

Then, he handed the magic gun to Hagrid.

"This magic bullet is filled with a descaling charm, Hagrid, you try it, just pull the trigger, and something magical will happen."

Convinced, Hagrid took the magic gun, and then, under Rhine's guidance, stood in the doorway.

The house was actually cleaned only yesterday, so it wasn't messy and didn't need to be cleaned at all.

But this was the friendliest and most shocking way to convince Hagrid of magical technology.

Hagrid, standing in the doorway, obscuring half of the light in the room, raised his hand and pulled the trigger.

Shout!

A pale green light flashed, and the room was suddenly cleaned like a whirlwind.

Countless foams appear out of thin air, cleaning floors and shelves.

A neatly folded rag on the ground next to him jumped into the bucket by himself, and the four corners were like limbs, rubbing around on the "body" to wash himself.

The foam penetrates deep into the cracks and the crevices underneath the cabinets, and in a few moments it changes color and clears out some dust.

In less than a minute, the rag rolls itself into a twist shape, wrung itself out, and folds it neatly into "tofu blocks".

The foam in the room gathered up quickly and burrowed into the barrel.

Then, the barrel floated slowly, left through the back door, and went to the bathroom.

I heard a loud bang, and after a while the barrel came back again, and it was already clean and new.

The air in the room was suddenly a little fresher than just now, and even breathing was more comfortable.

Hagrid was stunned the whole time, and he swore that he hadn't used any mana at all, and he hadn't chanted any incantations.

Moreover, Rhine next to him didn't even hold a wand in his hand, so it was even more unlikely that Rhine was secretly performing magic.

So, this magic gun that doesn't require mana or spells to cast magic is true!

"Rhine, where did this magic gun come from...... I mean, since there is such an amazing thing, it shouldn't be so obscure. ”

This time, Hagrid was genuinely intrigued.

This is the first time in recent years that he has become interested in non-living things.

Rhein felt his back straighter than before, and he walked back to the counter first, then turned around in style.

"This is my new invention, Hagrid, and you're the first to experience it besides me. If you want to buy it as the first buyer, I can give you a 7% discount for only 7 Galleons. ”

New Inventions...... Hagrid only felt that the image of Rhine in his heart suddenly became taller.

Previously, when Rhine was attending Hogwarts, his grades were very poor.

Aside from the fact that he had selected a completely useless "Hogwarts Sunshine Boy" and won the championship, there were no useful achievements at all.

Even graduating, it was not a normal graduation, and I failed to take the O.W.L.S exam.

Strictly speaking, Rhine is half a Hogwarts graduate.

But this half-graduate with a mess of grades can create such a miraculous invention.

Hagrid recovered from the shock, and he seemed to have a feeling that Rhine's life was about to change.

Eventually, Hagrid paid 7 Galleons for the ornate magic gun.

Rhein gave Hagrid three magic bullets, namely the "Disarming Charm", the "Levitation Charm", and the "Descaling Charm".

Hagrid was immediately overjoyed, and felt that this time he had made the right decision to buy the magic gun, not only did he enjoy the discount, but the ammunition did not cost money.

Sending Hagrid away, the corners of Rhine's mouth curled.

7 Galleons, make a lot of money.

Aside from his own manpower, the cost of a magic gun is probably only 2 Galleons, which is about the same as the material used in a wand.

The price is 10 Galleons, and Rhine also has its own considerations.

If you want to expand your influence, you can't be too greedy, although you are now a technological blockade, but if the price is too high, you will only dissuade wizards from ordinary families.

The price is about the same as that of a wand, which is what most wizards consume.

Now, the most important thing for Rhine is not to make money, but to make more people know and use magic weapons.

Hagrid buys his first magic weapon, and Rhine is already the first step towards his goal.

He believed that when Hagrid returned to Hogwarts, the butterfly would flap its wings and cause a chain reaction.

All we need to do now is to prepare for the storm.

Over the next two days, Rhine first spent 5 Galleons and went to the raw material market to buy a piece of wood.

Then, with the remaining materials from before, he made five magic guns and 108 magic bullets in one go.

It wasn't until all the wood in the shop was exhausted that Rhine stopped.

At this time, it was morning, and the sun was thick outside the window.

The Enbers Magic Shop, welcoming a second guest.

This man was also familiar to Rhine, even more so than he was to Hagrid.

Argus Filch, caretaker of Hogwarts Castle.

He was holding a very thin cat in his arms, dressed a little sloppily and with a sinister expression.

If you don't know someone, your first reaction when you see him will definitely be that this is a nasty weirdo.

And in fact, for Hogwarts students, Filch is indeed a nasty weirdo.

Filch was a Squib - Squib means, as opposed to Muggle.

Muggles are ordinary people who don't know magic in the first place, while Squibs are people who come from wizarding families but don't know magic.

Comparatively speaking, Squibs are much more miserable than Muggles.

Because Squibs have lived in the wizarding world since childhood, they can't do magic, they are simply outliers.

It feels like the whole class has a happy family, but I am the only left-behind child whose parents are divorced.

Filch was like that, he was the only Squib in the whole of Hogwarts, and his heart became a little twisted because of this.

Filch loves to torture students, and his room has many strange "torture instruments" waiting for a student who makes a mistake one day so that they can come in handy and satisfy distorted psychological needs.

To be honest, Rhein sympathized with Filch a little, but felt that Filch did not deserve sympathy.

The reason why I sympathize with him is because I was the "outlier" in my childhood in my previous life.

Rhein can relate to that feeling.

And the reason why Filch does not deserve sympathy is his perverted and distorted psychology, which is self-depraved.

Filch hunched over the counter, staring around with a thief's eyebrows, and without speaking, he slowly approached the counter.

Regardless of Filch's impression in his heart, after all, the visitor was a guest, so Rhine was the first to say hello.

"Oh! Mr. Filch, long time no see. How did you get time to come to Tumbledown Alley today, did you want to buy something? ”

Hearing Rhine's greeting, Filch's eyes focused on the figure behind the counter.

You could see that he was a little excited.

Hagrid said he had bought it at the Enberth Magic Shop.
