Bang—

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

The door panel was broken into several pieces, which was the result of Reiner's control of the smallest force. A burst of dust rose in the room, and it was a mess.

"What's wrong?"

The landlord hurriedly ran upstairs with his skirt in his arms, and was stunned when he saw all this.

"You you you you..."

"Don't worry, I will compensate 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 who received the compensation immediately smiled and returned to the downstairs without asking much questions.

Reiner looked at the dark room, which had several test benches, with optical microscopes, some ore samples, and more precision instruments. The room was originally very spacious, but after placing these equipment, it seemed a little crowded. Deep in the living room, Reiner saw the bedroom where the door was opened, and a man in old furry pajamas was rolling down from the bed in a panic.

"Who, who?"

He first saw his own door shattered 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 a lot of money."

Bratton immediately determined that he could not beat Reiner, so he immediately explained.

"Mr. Shockley Bratton, I was introduced by Born, the owner of the Singerna Fair's 'Singing Bones' store. I heard you have a deep study of spell casting materials."

"That guy Born?"

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

"Ah, you may not believe it. This door started first. I just pushed it gently and it became like this."

Reiner said half-jokingly, then added.

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

"Who are you?"

When Bradton heard this, he did not pay attention to the door. Since Reiner's force was just right, the door did not destroy any experimental equipment, and the mess looked a little indecent.

"Renner Ian Grey."

Reiner said, it seems that Mr. Bratton hasn't read the news newspaper for a long time.

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

After a half-beat slower, Bratton suddenly realized.

"Yes."

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

"Oh my God, I actually met Reiner Ian Gray, haha, it's incredible."

Bradton said as if incredible, with a mixed smile of surprise and excitement on his face.

"Mr. Bratton, I heard you have thorough research on the spell casting material, right?"

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

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

After Reiner asked this, Bradton fell a little from his floating state and nodded and replied.

"I have discussed with Mr. Born before, is there a material whose magic resistance is not a fixed value, but can be changed, or its magic resistance in different directions is different?"

Reiner asked straight to the point, causing Bradton, who was wearing old pajamas across the street to touch his chin and fall into thinking.

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

It seems that Bratton likes to say what he thinks in his heart while thinking. About two minutes later, a address book and a quill pen floated around Bratton, who was muttering to himself. He was writing something on it, and then raised his head.

"Mr. Ian Gray, the material you requested is really rare, unprecedented, and I'm afraid no wizard can study this material."

Just when Reiner felt that Bratton would not have any valid information, the other party continued to speak.

"But you are very lucky because I happened to find a kind of material like this recently!"

"I'll finish the words next time..."

Reiner whispered in a low voice. Compared to this, Bratton was even more surprised that he had found the material that Reiner needed.

"Wait, do you think there is really such material?"

"Yes, this is something commonly known as Heihuang Rock. It is produced in a few semi-plane volcanic areas. Its magic resistance will change greatly with temperature. At the same time, this rock has a special crystal structure, and its ability to conduct magic from the forward and the lateral direction is completely different."

Bradton said as if showing off his treasure, then ran to the test bench, searched for a while before picking up a small piece of rock contained on the glass.

This rock appears pure black under the light, but if you look closely, you can find a deep red like a flame spreading in it. Bradton gave Reiner a look, then placed it under an optical microscope, and then projected the picture seen by the microscope.

This is the structural diagram after the enlargement of the Heihuang Rock. It can be seen that its crystal structure is completely different from that of ordinary stones and is more orderly. At the same time, from the side and front, the structure is very different. Perhaps this is the reason for its magic resistance.

"You can look at the test."

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

When the constant magic power generation array was opened, Bradton demonstrated the characteristics of Black Soul Rock to Reiner. He saw that the intensity of magic power flow was significantly greater from the direction of the crystal structure, while the intensity of magic power flow was much smaller perpendicular to the direction of the crystal structure. Moreover, if a magic power was applied in the vertical direction, the magic power flow transmitted along the crystal structure would change.

Quite consistent with Reiner's expectations and requirements.

"How difficult is the processing of this kind of black-shen rock and how much is the output?"

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

"The processing difficulty is very low. As long as it is an alchemy workshop above the third level, it can be completely processed. As for the output, Mr. Ian Grey, this kind of thing is everywhere in those semi-planes. Before, because the magic resistance of these stones was not uniform, it was impossible to use it to make conventional magic materials. I also received samples from my friend and decided to study it."

Bratton looked at Reiner strangely, not sure why he asked that.

"That's great, Mr. Bratton."

Reiner was cheered up when he heard Bratton's words.
