Hogwarts: You are a devil!

"My little friend, you have such good eyesight. You picked out the best quality bottle of blood right away." The goblin who brought the blood praised.

"It's just luck. I didn't expect my luck to be so good. Please give me a price."

Louis pretended to be excited, as if he was just lucky and had accidentally fallen into the trap.

"There are ten Gu units of basilisk blood in the bottle. The market price is seventeen gold galleons per Gu unit. However, you are ordering urgent delivery. I can accept the charge of twenty gold Galleons per Gu unit." The goblin bypassed the shopkeeper. Said slowly.

Basilisk blood is too niche. Very few medicines use basilisk blood. If it weren't for the difficulty of killing the basilisk and the scarcity of the product, the price might be even lower.

"Okay, and let's give you a price for the herbs my companion has on hand!"

Pointing to the herbs in Sophie's hand, she had already prepared the magical plants she needed. They were all plants with hallucinogenic effects or good sweetness.

"Three magic mushrooms, three galleons, ten nightweeping grass... a total of 290 three galleons, sixteen kilos, and eleven knuts. Just give me 290 three galleons." "

The goblin shopkeeper calculated for a while, and said after erasing nearly one galleon of Sickle and Nat.

Without dwelling on such a small issue for too long, Louis quickly took out his wallet, found 290 three galleons and handed it to the goblin shop owner.

"Why not use the eyes of the basilisk?" Sophie asked curiously as she watched Fleur perform a series of tedious operations.

Eyes are the organs of basilisk petrified creatures. If you want to extract the petrifying factors, eyes should be better than blood.

"The number of eyes is too small. If you want to make petrifying potions on a large scale, blood is the best choice."

Fleur explained as she poured the prepared separation potion into the container in front of her.

After waiting for about 10 minutes, the dark red basilisk blood was divided into three layers: upper, middle and lower under the influence of the magic potion. Furong poured the three layers of liquid into different containers. This was the first step to separate cells and plasma.

The most useful one is the plasma layer, which is the top layer and contains various magic substances.

Take out three drops of plasma and drop them into the alchemical evolution device that is half a room in size. Adjust the evolution type to a basilisk. After placing the energy source, the evolution device will start running automatically.

The evolution device was temporarily borrowed from the academy. There are only seven such devices in the entire world. It is said to be an alchemy item left behind by fairies in ancient times. It can simulate the magical operation of most creatures and even wizards in the wizarding world.

The source of magic power is wizard currency refined by goblins. Each currency contains different amounts of magic power, and the value of the currency is divided according to the amount of magic power.

To activate the evolution device once, one hundred galleons are needed to provide magic power, which is really not something ordinary wizards can afford.

"Beep!" This was the sound that indicated the evolution was complete. The mouse was placed on the experimental table, and following the instructions in the instruction manual, Furong pressed a red button.

"Bang bang bang bang bang!"

The sound of the machine's movement frightened the mice on the experimental table. They ran around with their short legs and could not escape from the experimental table.

Immediately afterwards, a gray lightning-shaped light beam shot out from the raised part of the evolution device, covering the entire experimental platform.

After the light beam disappeared, a vivid stone sculpture of a white mouse appeared on the experimental table.

Great!The first step is basically successful, come on Furong, you can definitely do it!Fleur cheered herself up in her heart.

This is her first time to separate matter. Most alchemists may never come into contact with such advanced alchemy equipment as the evolution device.

It is simply too expensive, and most of the substances needed for modern alchemy were analyzed by wizards in ancient times.

Even the blood of the basilisk was studied by ancient wizards, but they did not develop a suitable magic potion, and the properties they discovered were not passed down, so Fleur needed to appear to study it.

After confirming that the petrochemical factors are in the plasma, the next thing to do is to separate the plasma substances and experiment step by step to find out the required factors.

This process may take a long time, or it may be very short. It all depends on Furong's luck.

It wasn't until the weekend three weeks later that Fleur found the magic substance Louis needed from the last bit of plasma separation fluid.

During the entire process, the evolution device was turned on more than 30 times, and more than 3000 galleons were turned into useless dirt.

In scientific terms, it is a special protease. When simulating a basilisk, the protease will release a strange power to petrify the enemy.

Next, Louis will study the conditions for petrochemical protease to take effect and use suitable potions to make it work.

He divided the research process into two steps. The first step was to prepare a chemical that would petrify humans or animals. The second step was to control the degree of petrification so that only the surface part was petrified.

"You came!"

"Yes, here I go again."

The goblin shopkeeper took out a few bottles of basilisk blood from under the counter. In more than a month, Louis bought basilisk blood from him thirteen times, almost emptying out the fresh basilisk blood in their store.

"Wrap these three bottles for me. Do you have any other basilisk blood? You know, the art festival is coming soon."

Picking out three bottles of basilisk blood that were in good condition, Louis asked. He had developed a petrifying potion, but the effect was somewhat different from what was expected.

The Paragu rat that drank the petrochemical potion is an XX-level magical animal that is widely used in experimental potions. The test results are similar to those of human test drugs.

The hair will be covered with a thick layer of stone armor. The stone armor will affect its actions, and at the same time it can defend against some damaging spells and offset some of the spells.

Similar to the sleeping spell, a spell that changes the state of a creature, stone armor can offset its sleeping effect.

The outer layer of stone is a dead object. If it is not penetrated, the magic spell will not harm the creatures inside the stone armor and will naturally have no effect.

As for the upper limit of offset and the specific defensive capabilities of the stone armor, it needs to be determined through human experiments.

"These are the last stocks in our store. The rest are all old blood that is more than 20 years old. If you need it, I can have it delivered."

All the basilisk blood within 20 years had been bought up by Louis. After all, few wizards would use this thing, so it could only be used as bottom-of-the-barrel goods, and they didn't have much prepared in the store.

One Gu's fresh basilisk blood can only be used to refine three Gu's petrifying potion stock solution. The petrifying potion given to Paragu Rat is a mixture of the original solution and neutralizing liquid at a ratio of [-]:[-].

The petrification power of the original liquid was so powerful that all Paragu rats who drank the original liquid turned into stone sculptures without exception.

Those who are lucky will recover automatically after a while, but those who are unlucky will still be stone sculptures until now, or their body parts cannot fully recover and remain in stone state.
