Hogwarts in Sharingan

The furnishings in the room are also very simple. There is a large table with various weighing tools, including small scales and even Chinese steelyards. However, Ethan does not need such a big one, so he picked one. A medium-sized scale, larger than the one they bought to use in Potions class.

That's right, Ethan is going to weigh the object before and after its deformation.

He directly took out a twenty-gram weight, transformed it into a very small ant, and then controlled it to weigh it, twenty grams.

Then, he turned a small weight into a big spider, still twenty grams.

This means that this is just an object change, and does not involve a change in mass. Moreover, after the living object is smashed to pieces, it will slowly change back, and the original object will also be broken.

However, when he used the small weight to turn into a large weight, the weight actually changed!

Similarly, when a large weight becomes a small weight, the weight also becomes smaller.

Ethan doesn't think that the law of conservation of mass is not observed in the magic world, so the mass that appears and disappears out of thin air must exist somewhere.

The roses conjured by Professor McGonagall prove this. The increased mass in the transfiguration comes from an unknown place, and the reduced mass will also disappear there.

But the question is, where is this place?

If it is an item in real life, wouldn’t we lose the item for no reason?

If not, what kind of place is it?

There are more and more questions, and Ethan feels like he is a scientist doing research in his previous life. The problem is that he has no knowledge in this field.

So Ethan turned to the library for help.

However, after searching for several days, I could only find hundreds of years of people's experience in transfiguration. No one had ever explored the origin of the summoned items.

In the eyes of Mrs. Pince, the librarian of Hogwarts, Ethan's behavior is very strange.

She had never seen the little wizard hanging out in the library in the first week of school. Except for classes and meals, the little wizard stayed in the library and didn't have many friends. At the beginning, there were three little wizards accompanying him. Looking at him, now only a little witch sat with him and read a book.

Moreover, he flipped through a book in just a few glances, and after he finished flipping through it, he picked up another one and started flipping through it. This was not like reading a book. If he hadn't read all the books on transfiguration and cared about the books, otherwise he would have He needs to be kicked out.

"Ethan, are you still going to the library?"

Hermione asked.

Today is Friday, and they only have Potions class in the morning. This is also their first Potions class. Ethan and Hermione are walking together on the way to the Potions classroom in the basement.

"I will go there in the afternoon as well, but instead of studying the transfiguration technique, I have to finish my homework first. Will you come?"

Hermione happily agreed to this arrangement.

Ron looked at Ethan in shock and said, "We have two days of weekend! Don't be so anxious to finish your homework."

Harry nodded in agreement.

Hermione was unhappy with their attitude.

"We can only review this week's courses and preview textbooks after we finish our homework. Otherwise, as the study progresses, we will become increasingly unable to keep up with the progress!"

Harry thought to himself that anyone in Hogwarts could fail to keep up, but the two of them were the least likely.

In the past few days of class, Hermione had taken on all the professor's questions. No one else could answer them, because she couldn't raise their hands as fast as she did.

Although Ethan is not very impressive, he can't be bothered by anything he needs to practice in class. Only the three people who know him best know that Ethan knows more than Hermione!

When they arrived at the Potions classroom in the basement, everyone frowned.

The classroom located in the basement feels very cold due to its geographical location. Also, because of the long-term brewing of potions, there is always an unpleasant smell in the air. Combined with some specimens of unknown creatures surrounding it, it makes people feel uncomfortable. People are afraid unconsciously.

[If this were used to make a horror movie, there would be no need for other props, it would just scare Muggles to death. 】

And the hero of our horror movie is none other than Professor Snape. From the beginning of class, he has crossed his arms, wrapped in a black robe, and looked at these little wizards with his cold eyes.

The little wizards were already trembling when they looked at him.

[I was wrong. If you were shooting a horror movie, you wouldn’t have to shoot it in a classroom. You could just shoot Professor Snape’s face. 】

"You are here to learn the precise science and art of potion-making, not to wave your wand foolishly. Here I can teach you how to increase your reputation, brew glory, and even prevent death - but there must be one , that is only if you are not the stupid idiots I often encounter."

Professor Snape's words combined with his serious expression made some young wizards feel as if they were suffocating. Only Hermione became excited, as if she wanted to stand up and prove that she was not a fool.

Ethan curled his lips. Every professor likes to show off and scare these ignorant little wizards. In fact, the curriculum at Hogwarts is extremely loose and it is a completely happy education. There has never been a student who repeated a grade because of poor grades. This If it were the students from the flower gardening family in the previous life who came here, everyone would be a top student.

Snape suddenly asked Harry: "What will I get if I add narcissus root powder to wormwood infusion?"

[Come on, come on, classic scene, Professor Snape makes things difficult for Harry Potter. 】

As expected, Harry was stumped by three consecutive questions, causing Gryffindor to deduct a point.

[Tsk, tsk, Professor Snape has a venomous tongue, but he still prefers Harry. Other students would probably be deducted ten points. 】

Hermione next to her was even more unhappy, not only because of Harry's trouble with Gryffindor, but also because she couldn't answer the question. Ethan probably had more to do with the second one.

"It has nothing to do with you, Professor Snape is just targeting it deliberately."

As expected by Ethan, when they were brewing a potion to treat scabies, all of them except Malfoy were made things difficult. Even Ethan and Hermione were accused of being too procedural.

But this is not Professor Snape's unreasonable behavior. In fact, there is one difference between what is written on the blackboard and the textbook, and that is the use of crushing venomous snake fangs.

The textbook says to put the dried nettles first and then the fangs, but the blackboard says to mix the two first and then put them in, which gives a better result.

That's not to say that it can't be completed using textbooks, but Professor Snape's method is obviously more useful.

This shows Professor Snape's skills. In the magic world, making potions basically relies on experience to estimate the effect of potions. Making even the slightest change requires extremely high talent and long-term accumulation.

"I felt like I was being targeted."

When get out of class was over, both Harry and Ron were complaining about Professor Snape's venomous tongue. Hermione did not speak out of respect for the professor, but she was also a little dissatisfied with Professor Snape.

"It's no secret that Professor Snape prefers Slytherin, but as a professor, he is still very powerful."

Ethan's words shocked Harry and the others, but he didn't care. People's prejudice against Professor Snape would hardly change in a short time.
