Greetings, Mister Principal: (Physics) Open the door

Bang——

The wooden door flew backwards in an instant, causing damage to the entire door frame.

The door panel was broken into several pieces. This was the result of Reiner controlling the minimum force. A burst of dust rose up in the room, and it was a mess.

"What's wrong?"

The landlord hurriedly ran upstairs with his skirt in hand. When he saw all this, he was stunned.

"You, you, you..."

"Don't worry, I will compensate you according to the price."

Reiner took out a gold coin from his pocket and threw it to the landlord, which was enough to install ten such doors.

The landlord immediately smiled after receiving the compensation and returned downstairs without asking any questions.

Reiner looked at the dark room. There were several test benches with optical microscopes and some ore samples, as well as more precision instruments. This room was originally very spacious, but after placing these The equipment seemed a bit crowded after that. Deep in the living room, Reiner saw the bedroom door with the door open. A man wearing old fluffy pajamas was climbing out of the bed in a panic.

"Who, who is it?"

He first saw the door of his house that was broken into several pieces on the ground, and then he saw Reiner.

"I don't have anything valuable here. These ores are ordinary stones and can't be sold for much money."

Bratton judged in an instant that he could not defeat Reiner, and immediately explained.

"Mr. Shockley Bratton, I was introduced by Bone, the owner of the 'Singing Bones' shop in Sedna Grand Bazaar. I heard that you have a deep research on spellcasting materials."

"That guy Born?"

Bratton felt a little relieved when he heard the familiar name. He looked at the door that was broken into several pieces on the ground, and he was afraid to ask what was going on.

"Ah, you may not believe it, but it was this door that opened the door first. I just pushed it gently, and it became like this."

Reiner said half-jokingly, and then added.

"Don't worry, the landlord has promised to replace one."

"Who are you?"

Hearing this, Bratton stopped paying attention to the door. Due to Reiner's controlled strength, the door did not damage any experimental equipment, but the mess looked a little inelegant.

"Lyner Iain Gray."

Reiner said, it seems that Mr. Bratton has not read the news for a long time.

"Mr. Iain Gray...wait, are you that Reiner Iain Gray?"

After a moment's delay in reaction, Braton was suddenly startled.

"Yes."

Reiner was used to other people's reactions. He shrugged helplessly and used his mage's hand to pull a chair and sit down.

“Oh my God, I actually met Rainer Inglete, haha, it’s incredible.”

Bratton said as if in disbelief, with a smile that was a mixture of surprise and excitement on his face.

"Mr. Bratton, I heard that you have done in-depth research on spellcasting materials, right?"

Reiner didn't want to waste time listening to other people's praise, so he asked directly.

"Uh, yes, yes, my research direction is indeed spell-casting materials."

After being asked by Reiner, Bratton came down from his dazed state a little, nodded and answered.

"I have discussed with Mr. Bowen before, is it possible to have a material whose magic resistivity is not a fixed value, but can be changed, or whose magic resistivity is different in different directions?"

Reiner asked straight to the point, causing Bratton, who was wearing old-fashioned pajamas across from him, to rub his chin and get lost in thought.

"The magic resistivity is not a fixed value... The magic resistivity in different directions is different. Well, this feature seems a bit complicated..."

It seems that Bratton likes to express his inner thoughts when he is thinking. About two minutes later, an address book and a quill floated next to Bratton who was muttering to himself. He wrote something and then raised his head.

"Mr. Ian Gray, the material you requested is so rare that it has never been seen before. I'm afraid no mage can study this material."

Just when Reiner felt that Bratton might not be able to get any valid information here, the other party spoke again.

"But you are lucky, because I just found such a material recently!"

"Next time, say it all at once..."

Reiner murmured in a low voice. Compared with this, he was more surprised that Bratton found the materials that Reiner needed.

"Wait, do you think such material really exists?"

"Yes, this is a kind of thing commonly known as black brilliant rock. It is only produced in a few volcanic zones in a few demi-planes. Its magic resistivity will change greatly with the temperature. At the same time, this kind of The rock has a special crystal structure, and its ability to conduct magic is completely different from the front direction and the side direction."

Bratton said as if showing off his treasure, then ran to the test bench, rummaged for a while, and then picked up a small piece of rock mounted on a glass piece.

This kind of rock appears pure black under the light, but if you look closely, you can find a deep red color like the spread of flames. Bratton gave Reiner a look, then put it under an optical microscope, and then The image seen through the microscope is projected.

This is an enlarged structural diagram of Black Huangyan. It can be seen that its crystal structure is completely different from ordinary stones and is more orderly. At the same time, the structures are very different when viewed from the side and the front. Perhaps this is its magic resistivity. Different reasons.

"You can look at the test."

Bratton opened the black cloth covering the test table again, and could see a whole piece of black rock on the table, with several wires connected in the middle.

Turning on the constant magic power generation array, Bratton demonstrated the characteristics of the black rock to Reiner. He saw that the intensity of the magic flow was significantly greater from the direction along the crystal structure, and perpendicular to the crystal structure. The strength of the magic flow is much smaller, and if a magic is applied in the vertical direction, it will change the flow of magic along the crystal structure. ~IndoMTL.com~ is quite in line with Lennar’s expectations and requirements.

"How difficult is it to process this black rock, and what is its output?"

Reiner asked hurriedly. If this was a very precious material, then he could only buy some for his own experiments. After all, judging from the name, this kind of stone seemed quite noble.

"The difficulty of processing is very low. As long as it is an alchemy workshop of level three or above, it can be completely processed. As for the output, Mr. Ian Gray, this kind of thing is everywhere in those demiplanes. Previously, it was blocked by the magic power of these stones. The rate is not uniform, so there is no way to use it to make regular magic materials. I only decided to study it after receiving samples from my friends."

Bratton looked at Reiner strangely, not knowing why he asked this.

"That's great, Mr. Bratton."

Hearing Bratton's words, Reiner was cheered up.

His plan for a magical computer looks like it could come true.
