i sold arms at hogwarts

After some haggling, Remy reluctantly agreed to sell Professor Snape five magic crystals for 2 credits each.

The price is very low. After all, apart from winning the Academy Cup in the end and getting some honors, the academy points do not add any actual attributes.

But Remy sold anyway.

Because Remy felt that since he randomly placed magic crystals to strengthen the effect of the water of life and death, and it was officially certified by Professor Snape, then the magic crystals should also have a strengthening effect on other potions.

As a master of potions, Professor Snape has at least dozens of potions, not to mention hundreds or thousands of them, right?

With such a magic crystal lying around, he couldn't do all the experiments?

That's a lot of money!

Only by putting a long line can you catch big fish!

"Professor Snape, let's talk first. This time, I agree to sell you the magic crystal at such a low price because I poisoned you before. If you need the magic crystal again in the future, it won't be at this price... and You may not be able to buy it with college points!" Remy said.

Credit trading will definitely not go ahead after Snape knows the contents of the Academy Cup reform. Moreover, Remy has long coveted Snape's exclusive magic blade, Shadowless Blade. To be precise, Remy is eager to see through any magic.

hum~

Snape hummed softly, carefully put the magic crystals into a bottle, immediately turned his back on himself, took out his wand and repaired the door.

Being locked up again, Remy hummed a song in a good mood, and used alchemy to create a large piece of obsidian at the door to block it tightly.

Now it's not Remy who is locked up in the solitary room of Hogwarts Castle, but Remy who has been locked up in the Hogwarts Castle!

This is the legendary theory of relativity!

Also known as the spiritual victory method!

Another foreign kid’s perspective on the world!

In the middle, Professor McGonagall came over and used transfiguration to remove the obsidian blocking the door several times, but every time Remy turned around and sealed it again. After three trips back and forth, Professor McGonagall didn't bother to care about him anymore.

Maybe it was because Remy was imprisoned on a Friday, or maybe because Remy was doing well, he was released near noon on Monday of the second week.

Just in time not to delay the new week of classes.

When Filch informed Remy in an angry voice that he could leave, and when Principal Dumbledore personally used Transfiguration to remove the boulder that sealed the door, and looked at Remy who was lying on the rocking chair and shaking a glass of red wine, both of them were silent. .

"Oh, Principal Dumbledore, you are here."

Remy jumped up and placed the red wine glass on the table, while waving to Principal Dumbledore.

"You came just in time. I have a brand new invention here and I'm waiting for you to take a look." Remy said.

Brand new invention?

Was it invented without an explosion?

Surprised and curious overcoming speechlessness, Dumbledore pushed up his glasses and walked into the solitary room and looked at the two oil lamps on the table.

The two oil lamps are exactly the same, the only difference is that one is brighter and the other is dimmer.

"Are they these two oil lamps?" Dumbledore asked curiously.

"That's right!"

Remy nodded vigorously, then walked to the door and sealed it again with stones, then approached the oil lamp and blew it out in one breath.

As the oil lamp was blown out, the confinement room suddenly fell into darkness without even a trace of light.

"Headmaster Dumbledore, you can use the lighting spell now," Remy said.

Dumbledore nodded. He didn't even take out his wand, but showed off a wandless spell + silent cast. He just raised his hand and held up a ball of light.

As light appeared, one of the oil lamps on the table suddenly burned, giving the room a warm orange-red color.

"This is……"

"This is my latest invention - a light-sensitive oil lamp!"

Remy picked up the burning oil lamp with a look of pride on his face.

"This oil lamp can light up as long as there is light, and whether it is the light from other oil lamps, lighting spells or sunlight, as long as it is light, as long as there is light within its sensing range, it can light up! Completely automated! Very humane!”

Dumbledore blinked and thought.

It sounds amazing, but why does it always feel like something is not quite right?

"What if there is no light? Can it still shine?" Filch asked.

"Good question! Principal Dumbledore, could you please turn off the lights?"

When Dumbledore turned off the lighting spell, the room suddenly went dark.

"See? If there is no light, it will never light up!" Remy said.

Dumbledore:  …

Boil!

I just said something is not quite right!

"But it can be activated in other ways, such as..."

Remy clicked a match and used it to light another oil lamp.

When the match burned, the oil lamp lit up.

When another oil lamp is lit, that oil lamp continues to light.

only……

"Why do I feel that the brightness of this induction oil lamp is not as bright as the ordinary oil lamp next to it? Am I confused?" Dumbledore asked.

"It's a light-sensitive oil lamp." Remy corrected: "You are not wrong. Its brightness is only 50.00% of the nearby light source, which is half... After all, there is a loss in energy transmission, right?"

Dumbledore:  …

You are really scientific, but why would you design something so unscientific?

And this is a magical world!No need to talk science!

"Remy, I'm a little confused. It would be fine if it could enhance the light source, but since it is only half as bright as the nearby light source, and it seems that its sensing range is also very small, then what is its use?" Dumbledore asked in confusion.

Remy scratched his head and looked puzzled: "I didn't think I said it was useful, did I?"

Dumbledore:  …

In other words, it really has no use?

Then you invented it to dry wool!

"If I have to talk about its function, I think it can be used as a teaching prop to convey some concepts more intuitively... although I have not thought of any concepts that it can convey."

Shaking his head, Remy pointed to the two oil lamps on the table.

"Here you go, my beloved principal. Also, please open the door for me. I can't push that stone." Remy said.

Ugh……

Sighing, Dumbledore waved his hand and cast a wandless spell again, but this time he used a levitating spell.

Remy looked very envious.

As soon as he walked out of the door, Remy suddenly looked into the room again.

"Oh, by the way, I just forgot to introduce it. This light-sensitive oil lamp does not require light to shine directly on it. It only needs a light source within a spherical area with a radius of one meter to light up... It also has light, but the brightness is Not ideal,” Remy said.

Is that so?

Dumbledore picked up the oil lamp on the table and fell into deep thought.

If that's the case, it might be of some use. It seems like... it can be put in a secret room.
