Hogwarts: You are a devil!

Regardless of mistakes, each Gusi basilisk blood can be refined into 24 Gusi petrifying agents, each bottle is ten milliliters, which is about 72 bottles of petrifying agents.

Taking into account various mistakes, the actual output is only about [-]:[-], and the ratio can be improved a bit after becoming proficient.

The raw materials used to make one Gusi blood are worth sixteen Galleons. Excluding labor costs, the raw materials needed to refine one Gusi Basilisk blood are 33 Gold Galleons.

Taking into account labor costs and various research and development expenses, Louis and the others initially set a price of three galleons per bottle.

This is a potion that can replace the Iron Armor Curse, and is even more effective than the Iron Armor Curse. Although the effect is a bit unstable and the side effects are quite strong, in the absence of a substitute, Louis thinks the sales should be pretty good.

Later in the original work, the British Ministry of Magic also ordered [-] sets of alchemical defense equipment from the twin brothers that could cast the Iron Armor Curse. This shows that there are still a large number of Aurors who are not proficient in the Iron Armor Curse.

There is a saying in the wizarding world that is spiritualism in the release of spells. The more the state of mind is in line with the creator of the spell, the easier it is to release the spell.

Whether the specifics are true needs to be considered. There are indeed a large number of wizards who are not good at, or are only good at a few kinds of magic spells and know nothing about other magic.

Lockhart is an example. After graduating from Hogwarts, he only knew the magic of the Forgetting Curse. I have no idea how he graduated from Hogwarts.

Is it possible that Deng relaxed his discipline after taking over Hogwarts?Louis didn't know, he didn't want to know, and he wasn't going to Hogwarts anyway.

As long as Voldemort is not eliminated, Louis has no intention of setting foot in the area where Hogwarts is located. Once Voldemort is gone, he is interested in going to the Hogwarts library to learn about the books in it.

At this point, all the books in the Beauxbatons Academy library are basically backed up by the Lestrange family. The ancestors of Louis have long since brought home all the knowledge they can bring home.

There are also many books in it that Beauxbatons does not have, which is a reflection of a family's heritage. The descendants of the family can use that knowledge to become much stronger than ordinary wizards.

It's a pity that those books are all in the old house in Paris. Anne's castle only contains some works on potions, which were Louis' main study objects in the past few years.

After preparing the petrochemical potion, now is the last step to put it on the market. Find a few brave testers to test the potion.

Louis originally wanted to go to the Muggle world and capture a few condemned prisoners to serve as guinea pigs. The process was not too complicated. If the Muggle Expelling Curse was applied, ordinary people around him would automatically ignore the condemned prisoners.

Fleur and Sophie stopped him. Doing so would not only attract the prying eyes of the Ministry of Magic, but would also worry about the potion corroding ordinary people.

Due to the magic power existing in wizards, essentially, wizards and humans are no longer the same species, and there are slight changes in their bodies.

Magic power flows in the veins of wizards, and there is a special magic power storage organ in the body. It is said that it is located in the head, and the magic resistance is much higher than that of ordinary humans.

When it comes to testing potions, human death row prisoners are not as cost-effective as brave little wizards. There are many such brave people in Beauxbatons. They are frequent visitors to the school doctor's office and earn a lot of savings by testing potions for others.

When Louis explained his purpose, a large number of young wizards overcame their inner resistance to Louis under the temptation of Jin Gallon and took the initiative to come to him and ask him to hire them.

In the end, Louis hired ten young wizards at the price of ten galleons each. They were from grades one to five, one male and one male. Louis would use them to test the effect of the petrification potion.

"The potion in your hands is called petrification potion. Its effect is to generate a layer of stone armor on the surface of the human body. I have tested the specific effect on Paragu Rat, so you can rest assured."

This matter is related to the success or failure of the petrified potion. Louis' trio all came and stood at the edge of the test site to watch the effect of the potion.

The testing site is right next to the school hospital. No matter what problems there are, the magical school doctor can save the lives of these little wizards.

The potion testers had long been experienced in testing potions, and without Louis' instructions, they took the initiative to unplug the cork on the potion bottle and poured the gray potion in the bottle into their mouths.

Deep feelings make you feel stuffy. This is their experience. As long as I drink it quickly, no matter what the taste of the potion is, it will not affect me.

Some potions are really terrible to drink. They are a hundred times worse than the Ganges River water where corpses are soaked in a certain country. The smell of smelly socks, the smell of moldy underwear soaked in water and rags. There are countless potions, and half of them are terrible to drink. .

The first one to take effect was the first-year wizard. The thick stone armor continued to extend from his legs and soon covered most of his body.

After a while, he was wrapped in stone. His face, right hand, potion bottle and wand in his hand looked like they were petrified.

The wizards who tested the medicine suddenly panicked. They were here to make money, not to risk their lives. Who knows if the school doctor's office can cure petrification? It's not that they doubt the level of the school doctor's office, but they always have doubts about unknown things.

At this moment, the stone man moved. He first moved his feet stiffly, then his hands and head. He looked like an insect wrapped in a pupa, which could also be said to be a clown.

The dose of petrification is too high, Louis thought silently in his heart. It seems that the resistance of wizards to potions, at least in terms of petrification potions, is not as good as that of small things like Paraguru.

Seeing that nothing happened to him, the other little wizards quickly drank the potion in the bottle.

After a while, ten statues with moving bodies appeared on the test site, which also attracted the attention of some young wizards. The petrifying potion was famous.

With the experiments of these little wizards, Louis quickly prepared a batch of petrochemical chemicals with a ratio of [-]:[-] of original solution to neutralizer, as well as various ratios of [-]:[-], [-]:[-], [-]:[-], etc. Petrochemicals.

Twenty young wizards were selected again, and Louis asked them to test four ratios of potions. The most effective one was the petrifying potion in a ratio of [-]:[-].

The little wizard who drinks these potions will have stone armor appear on most parts of his body, including the thighs above the knees, both hands above the elbow joints, and the chest and abdomen.

Among them, the petrified armor on the chest and abdomen is the thickest and has the best defensive effect. This part is also the most vulnerable to attack.

The petrified armor on the thighs and arms is thin, affecting about [-]% of the movement speed and half of the casting speed, and the side effects are relatively weak.

There is also a one-to-ten version, which can only protect the chest and abdomen, and the protective power is weakened by [-]% compared to the one-to-nine version, but it will not affect the wizard's movement.
