Harry Potter: The Atypical Alchemist

The injury on his hand was actually not serious. The wound was still there but no longer bleeding. There was no need to go to the school doctor's office. After bidding farewell to Hermione and the others, Stone returned directly to the Ravenclaw common room.

Sure enough, the Halloween dinner had been brought back. It was indeed very sumptuous, and Stone's appetite increased greatly.

At this time, Penello came over and frowned:

"Where have you been? Why are you back now? Do you know how dangerous it is outside?"

"It's a troll, we just killed it."

"You..." Penello was speechless for a moment, and then saw the wound on Stone's hand.

She held Stone's finger, bent down and raised the wound to her eyes:

"How did you do it?"

"Fight the troll."

"Really?" Penello was already a little convinced.

"real."

"Huh-ok." Penello took out his wand and pointed it at Stone's wound. The next moment, a soft light emitted from the top of the wand.

The cool light covered the wound, and it didn't take long for Stone's tiger's mouth to be completely healed.

"Are you hungry? Let's go eat." Penello took back his wand and patted Stone on the head.

She didn't care what the truth was, she would know it tomorrow anyway, at least the prefects could know it. All that mattered right now was that she knew Stone was safe, and that was enough.

The dinner lasted for a long time. After it was over, Stone, who returned to the dormitory, took out his notebook and started writing and drawing.

The talisman spectrum has been designed, and the choice of talisman cross is tentatively made of metal.

But which metal to choose posed a dilemma for Stone.

First of all, this metal cannot be too hard, because his carving knife is the worst kind.

The quality of the carving knife is reflected in two aspects, the smoothness of the transmission of magic power and the hardness of the carving knife itself. He can't feel the first one for the time being, but the hardness is very intuitive. When his carving knife hits hard metal, There is a risk of blade chipping.

Secondly, this metal needs to be able to transmit energy well, and one-way energy supply has extremely high requirements for this.

After excluding some things that Stone didn't know, among the remaining choices, the best ones were actually gold and silver. This was also the point where Stone struggled...it was too expensive.

If he were in the Muggle world, he could still do a little bit, but in the wizarding world, he only had seven gold galleons. What was enough for him?

Wait...Gold Galleons?

Stone took out his gold coins and murmured:

"Golden Galleons are gold, right? There should be no currency protection laws in the wizarding world, right?

"But...the uneven golden Gallon is not easy to engrave talismans on.

"Eh? You can melt it away!"

The more he thought about it, the more reliable it became, so Stone took out his crucible.

Putting the gold coins inside, Stone stopped when he was about to light a fire.

—His cauldron was of pewter.

The melting point of pewter is very low, nearly five times lower than that of gold. If the gold is not melted by then, the crucible will be scrapped first.

In addition, he also needs to find a mold to hold the melted gold water.

Brass can be used for the mold, but not the crucible. Although the melting point of brass is higher than gold, it is not much higher. Stone is afraid that he cannot control the heat, so he has to use a crystal crucible, or at the very least, a quartz one.

Students who take Potions as an elective in their senior year should have a cauldron like this.

So......

"Senior Penello - lend me your crucible -" Stone stood in front of Penello's dormitory door, rubbing his palms and smiling broadly.

"What are you going to do?" Although there was helplessness in his words, Penello still found a new crystal crucible, "Here, here you go, do you need anything else?"

"Any brass?"

"A brass cauldron?"

"Anything will do." Stone replied. The mold has no requirements on the shape of the object. He can use transformation.

"Yes." Penello pulled out an obsolete brass scale, but this time she did not hand it to Stone directly. Instead, she closed the door and entered his dormitory with Stone. She wanted to see what he was doing.

Anthony was also in the dormitory, but seeing Penello was like a mouse seeing a cat. He quickly ran to the dormitory next door for a visit, and his bed became empty.

But there are differences between men and women, and Penello sat on Stone's bed. After all, his son...er, brother, his brother is not an outsider.

Stone took the brass scale, turned it into two rectangular molds, and then loaded the gold coins into the crucible.

He whipped out his wand: "The flames are blazing."

Flames burst out of the crucible, and Stone continued to output magic power, and the flames burned fiercely.

After a long time, the temperature in the room rose a lot, but the gold coins in the crucible did not change much.

"Are you going to melt the Galleons inside?" Penello finally couldn't help but ask.

"um, yes."

Regarding this situation, Stone was also a little helpless. The problem was still the same. The fire-making spell was just a life spell, and his own magic level was only at the level of an ordinary student. He could only increase the temperature of the flame through a steady stream of magic power.

Penello pursed her dry lips:

"How about I come? I'm afraid you'll bake yourself dry before the gold coins melt."

"Uh...Okay." Stone quickly withdrew his flame, which was indeed a little hot.

Penello took out his wand, and Stone went to drink water. In just one drink of water, when he came back, the gold coins had almost melted.

He was stunned for a moment, and then heard Penello's words:

"Okay, do you want to pour it into the mold?"

"Huh? Well, yes."

The flame in the crucible was not extinguished, like a cup of golden wine on fire.

The wine was poured into the mold, the faint flames above gradually dissipated, and some impurities were also separated out.

After cooling, Stone picked up the two molds, one in each hand.

After a "ding——" sound, two thin rectangular gold plates were buckled onto the desk.

The two molds are exactly the same, and Penello's control of the gold liquid is not bad at all. There is no interference during cooling. The two gold plates directly reach the state of being ready for use after leaving the factory without polishing.

He put the two gold plates together and took out his carving knife.

Only when he got here did Penello understand what he wanted to do and asked:

"You want to make alchemy again?"

"Yeah, don't worry, I've redesigned the steps, there won't be any danger."

"Is there really no danger?"

"Of course, it's just three runes. I've tried it many times."

Hearing this, Penello's eyebrows instantly stood up. She didn't know about runes or talismans, she only knew that Stone almost got herself into the hospital again, and "many times"!

She suppressed her desire to speak. She was afraid that she could not help but criticize Stone and affect his mentality.

Stone is about to start carving the runes.
