Teacher Claire is puzzled, while Xia Luo is surprised.

"Principal Ian Gray, are you serious?"

Teacher Claire first asked, in her cognition, this useless principal almost didn't know magic, and never cared about academic matters, let alone students' learning problems, and now suddenly said such things, is she making fun of herself?

To be honest, Teacher Claire didn't think that Reiner could read a single word on the test paper, so she was very impatient, she hadn't dealt with Reiner a few times, and she couldn't tell that the soul of the principal in front of her had already become a different person.

"Teacher Claire, I think we should be more tolerant of the students, and we shouldn't deny her ideas with that kind of tough attitude, at least, she thinks about it, doesn't she?"

Out of the corner of Reiner's eyes, he could see that the answers to the other papers on the table were the same, and it was obvious that he had memorized the description from the book.

He told the truth that he was still in a trance, but his sense of responsibility as a teacher made him unable to just make a special student lose his curiosity for knowledge, and Reiner himself had a lot of curiosity about the magic of this world, so for various reasons, he decided to find out whether Xia Luo's statement was correct or not, and how much of his knowledge on the earth could be applied to this world.

"But her thinking is completely wrong, the fire element theory is a great theory discovered by Master Hohenheim three hundred years ago, and it is the cornerstone of modern alchemy, I don't think a mage apprentice can overturn this theory so easily."

Teacher Claire was stunned by Reiner's words, and then retorted, but her attitude softened, perhaps because she felt that there was a little bit of truth in Reiner's words.

"If religion begins with faith, then magic begins with doubt."

Reiner changed what he had heard in his previous life and continued.

"Why don't we first hear how Xia Luo came to this conclusion before denying her?"

Hearing Reiner's words, Xia Luo's eyes lit up, and she was immediately impressed by this principal, who didn't seem to be very reliable.

Although the headmaster Ian Gray has a bad reputation, at least he is willing to listen to his own explanation rather than blindly deny it like Teacher Claire, and from this point of view, Reiner's reputation has increased by at least ten points with Xia Luo.

Of course, the perfect score is a hundred points.

"Okay, then Xia Luo, you can tell me."

Teacher Claire shrugged helplessly and motioned to Xia Luo to explain.

"Well, I first found out that this possibility was an experimental mistake."

Xia Luo thought for a moment and organized the language before speaking.

"Originally, I wanted to heat the limestone at a high temperature to get white rock, and normally, this experiment should use a non-closed container, but I made a mistake at that time and used a closed flask."

Reiner didn't understand what limestone was and what white rock was, and seeing his puzzled expression, Teacher Claire sighed lightly and explained.

"Limestone is a rock that can be found everywhere, and white rock is a special kind of stone that dissolves into water."

As she spoke, she lamented why she had to listen to Charlotte here with the headmaster, and Teacher Claire felt that she had been fooled.

When Reiner heard this explanation, he quickly figured out that the so-called limestone and white rock should be limestone and quicklime, and this reaction is the basic experiment of junior high school chemistry, and the reaction between the gas, carbon dioxide and clarified lime water produced in the experiment is also one of the most classic enlightenment experiments.

"After heating, I noticed that some kind of gas seemed to appear in the flask, and when I used the catheter to remove it, the flame of the alcohol lamp was extinguished."

Charlotte explained succinctly, looking at Reiner and Claire from time to time, paying attention to their expressions.

"According to the theory of the fire element, this is impossible."

Reiner then flipped through a book on alchemy on the table and followed the table of contents to find the chapter on the element of fire.

"The fire element exists in everything, when the matter is burned, the fire element is released to produce flame, the matter loses the fire element, it becomes dead ashes, the ashes gain the fire element, the matter will be resurrected, the specific process of combustion can be simply expressed as: matter (combustion) = fire element + ashes.

—Introduction to Alchemy, Chapter 3, Section 1, by R.V. Hohenheim, 3rd ed. 2036."

There is no mention of gas being produced during the combustion process, so what is this gas that can extinguish the flame, and where does it come from?

Of course, Reiner could tell Charlotte that the gas was carbon dioxide, a compound produced by the reaction of the carbon element in calcium carbonate with oxygen in the air, but if they said so, they would definitely not believe it, and Reiner would need more arguments to prove that the carbon dioxide in this world is the same substance as the earth.

"Why don't we go to the lab and replicate this experiment?"

Reiner's suggestion made Xia Luo's eyes widen slightly, she originally thought that Reiner just wanted to fight against Teacher Claire, but she didn't expect that the headmaster really believed in herself, which made the girl feel a little incredible.

"Experiments?"

Teacher Claire was visibly more surprised, and she looked Reiner up and down with a look that looked like a madman, and opened her mouth to confirm.

"The experiment you're talking about is an alchemy experiment?"

She didn't even know if Reiner knew the meaning of the word experiment, and in the impression that Teacher Claire had since she was a child, the nobles were all unlearned and unskilled, especially when she was five years old, after being bullied and crying several times by an unknown little nobleman, this impression was ingrained and could never be changed.

"Of course, Mr. Claire, what do you think I'm talking about?"

Reiner's attitude was a matter of course, which made Teacher Claire feel a little displeased, as if he was the uneducated one.

"If we can reproduce the experiment described by Charlotte in its entirety, and if we can get the same results, does that mean that there is some truth to her conclusions?"

"Impossible, if the theory of fire elemental combustion is wrong, then in the past three hundred years, all the alchemy papers have to be rewritten, but we have accomplished so many great things on this basis, do you want to deny the contributions of those great mages?"

Teacher Claire's tough attitude caused Reiner a bit of a headache.

This guy is too stubborn.

Reiner thought about it, this kind of guy with an iron head, I'm afraid it can't be done on the front, so he has to take a detour.

"Teacher Claire, are you afraid that Xia Luo has proved that her conclusion is correct?"

He used the agitation technique, which caused Teacher Claire to jump immediately.

"Who said that, I won't be afraid, it's the alchemy masters who stand behind me for three hundred years!"

The results are outstanding.

As soon as the words were spoken, Teacher Claire knew that she had been calculated by Reiner, but after thinking about it, she felt that this was an opportunity to punish the unreliable principal, so she said.

"But if it turns out later that the fire elemental theory is correct, you'll have to pay a price."

"Uh, of course, what do you want me to do?"

Reiner didn't expect this woman to be so crisp, so he was stunned before asking.

"Well, why don't you just ...... At next week's morning meeting, put on your skirt and run ten laps around the square! ”

Teacher Claire thought for a moment, then continued, but Reiner was taken aback.
