What came from Teacher Claire was confusion, but what came from Charlotte was surprise.
"Headmaster Iain Gray, are you serious?"
Teacher Claire first asked. In her opinion, this useless principal knew almost no magic, had never cared about academic matters, and did not care about students' learning problems. Now he suddenly said this , are you taking pleasure in yourself
To be honest, Teacher Claire didn't think that Reiner could understand a single word on the test paper, so she seemed very impatient. She had not interacted with Reiner a few times, and she couldn't tell that the principal's soul in front of her had already become another person.
"Teacher Claire, I think we should be more tolerant to our students and not deny her ideas with such a tough attitude. At least, she has thought about it, hasn't she?"
Reiner glanced at the other test papers on the table, and could see that the answers to the questions on several test papers were exactly the same. It was obvious that he had recited the description in the book.
To be honest, he was still in a trance of time travel, but his sense of responsibility as a teacher prevented him from making a special student lose his desire for knowledge. Reiner himself also had a lot of curiosity about the magic of this world, so everyone Under the influence of various reasons, he decided to find out whether Xia Luo's statement was correct and how much of his knowledge on 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. It is the cornerstone of modern alchemy. I don't think a mage apprentice can overturn this theory so easily."
Teacher Claire was stunned when Reiner said this, and then she retorted, but her attitude softened a little. Maybe she felt that there was a little bit of truth in Reiner's words.
“If religion begins with belief, magic begins with doubt.”
Reiner changed what he heard in the previous life and continued.
"Why don't we first hear how Charlotte came to this conclusion before denying it?"
Hearing Reiner's words, Xia Luo's eyes lit up, and she was immediately impressed by this seemingly unreliable principal.
Although Principal Iain Gray has a bad reputation, at least he is willing to listen to his own explanation instead of blindly denying it like Teacher Claire. From this point of view, Reiner's reputation with Charlotte has increased by at least ten points.
Of course, the perfect score is one hundred points.
"Okay, then Xia Luo, tell me."
Teacher Claire shrugged helplessly and motioned for Charlotte to explain.
"Well, I first discovered this possibility as an experimental error."
Xia Luo thought for a moment and organized her words before speaking.
"Originally, I wanted to heat limestone at high temperature to obtain white rock. Generally speaking, this experiment should use an unsealed container, but I made a mistake at that time and used a closed flask."
Reiner didn't understand what gray rock was and what white rock was. Seeing his confused expression, Teacher Claire sighed and explained.
"Limestone is a rock that can be seen everywhere, while whitestone is a special kind of stone that can dissolve into water."
As she spoke, she lamented why she had to listen to Charlotte's explanation here seriously with this principal. Teacher Claire felt that she had been truly fooled.
After hearing this explanation, Reiner quickly understood that the so-called limestone and white rock should be limestone and quicklime. This reaction is a basic experiment in junior high school chemistry. The gas produced in the experiment, carbon dioxide, reacts with clarified lime water. It is also one of the most classic enlightenment experiments.
"After heating, I found that some kind of gas seemed to appear in the flask, and when I used a tube to lead it out, the flame of the alcohol lamp was directly extinguished."
Xia Luoyan explained briefly and concisely, 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 immediately opened an alchemy book on the table and followed the table of contents to find a chapter on the element of fire.
"The element of fire exists in everything. When matter burns, the element of fire is released to produce flames. When matter loses the element of fire, it becomes dead ashes. When the ashes gain the element of fire, the matter will be resurrected. The specific process of combustion can be simply expressed as: Matter (combustion) = fire element + ashes.
