By the time the first rays of sunlight shone into the plaza of Crescent Academy, Reiner had already gotten up, changed into a clean and comfortable shirt, picked up the notes he had taken in the past few days, and prepared to head to the lab.

From Reiner's tower to the laboratory building, a few students had already risen early, and even though it was a day off, some of the well-educated aristocratic ladies had adopted healthy habits, some silently practicing magic in the corner of the empty square, and some were preparing to go to the classroom with books in their hands.

The morning light shimmered on the dewdrops, and the slightest coolness of the night had not yet faded, Reiner greeted the girls on the side, but the aristocratic ladies were obviously still wary of Reiner, only a cheerful student replied to greet, Reiner didn't care about these details, and walked straight towards the laboratory building.

There were many vacant classrooms, and Reiner took the key Claire gave him, went to one of the labs, took out the necessary experimental equipment from the cupboard, and began to assemble the equipment for the experiment.

The process of the electrolysis experiment is described in detail in the paper, and for Reiner, who has apprentice-level magic powers, the biggest difficulty may be the arrangement of the electrolysis circle.

But Reiner naturally has a way.

Just after he had assembled all the equipment, Teacher Claire also happened to bring Xia Luo here.

As a first-ring mage, Claire was obviously able to support the operation of the electrolysis circle, so Reiner "invited" her to participate in the experiment.

As for Charlotte, Reiner thought it was necessary to cultivate a scientific spirit for her in advance, and by the way, to relieve the fatigue of her recent rush to paint, so she also let Claire pick her up.

"What are you going to do?"

Claire looked at the sink full of water, a little confused.

"Electrolysis."

Reiner replied, then spread out the Alchemy to the Seven-Ring Mage Cornwall. Penzance's Papers.

"Electricity can decompose some reactive elements, and I designed this experiment to decompose a substance that people didn't think could be broken down in the past."

Following Reiner's words, Claire and Charlotte looked at the location he was pointing, but there was nothing but a basin of water.

"Is this some kind of solution, it's still some kind of special liquid, but it feels like ordinary water no matter how you look at it......"

Claire asked, but she soon understood Reiner's intentions.

"Uh, no, you mean, water?"

Hearing Claire's words, Charlotte's eyes widened and she looked at Reiner in disbelief.

Water, one of the four basic elements proposed by Master Hohenheim, represents life, and in the field of ancient magic, magic is not even a faction like elemental, alchemy, but simply divided into the four major factions of Feng Shui, Fire and Earth, and water has been considered inseparable since ancient times.

In fact, at the beginning of modern magic, mages tried various methods to break down water, they burned, froze, struck, many times, they succeeded in obtaining something from water, but it was later proven that it was nothing more than an impurity, and water is still regarded as the building block of the world, one of the four basic elements.

"I've said before that you'll try to break down the water when you're well prepared."

"But in the past those people's attempts, even if it was heated, the water would only turn into water vapor, and the mages have exhausted all kinds of means for hundreds of years, but they still have not succeeded."

Claire argues that she emotionally thinks Reiner is talking nonsense, but after previous experiments, she intellectually expects Reiner to succeed, and this ambivalence leaves her torn between two sides.

"But they didn't use thunder and lightning."

Reiner's words left Claire speechless, and then, he added with a slight teasingness.

"Why don't we make another bet, I miss you in a maid's outfit a little, Miss Claire."

This sentence made Claire's cheeks crimson, and she turned her face away with some indignation.

Xia Luo watched the interaction between the two and sighed helplessly.

"Since there is no objection, I will say my own thoughts."

Reiner did not experiment directly, but gradually, on the one hand, to pave the way for the future.

"First of all, is it reasonable to assume that water is a chemical compound that cannot be broken down because the elements that make up it are so reactive that they can easily react with other substances?"

"Well, if water is indeed a chemical compound, then that's fine."

Claire reluctantly said that most of the elements found so far are metals that exist in nature as elemental substances, and the nature of the elements is particularly lively, and it is indeed rare to hear of them.

"Then, according to the paper of His Excellency Penzance, the new element 'Kayla' obtained by electrolysis is an extremely reactive metallic element that can even react directly with water."

Continuing with the previous words, Reiner pointed out the passage in the paper on "Alchemy" about the nature of the new element "Kayla". Penzans is worthy of being a high-level mage, and his experiments on nature are quite comprehensive, and he has almost perfectly described the nature of this element.

All these high-level mages lack is some inspiration, and in many cases, they are not unexpected, but just "haven't thought of it yet", and if they are given a little spark of thought, then they can create colorful modern theories without Reiner's hands.

Back in the lab, the reaction between "Kayla" and water should be a displacement reaction, in which "Kayla" replaces the hydrogen in the water to produce hydroxides and hydrogen gas, at least on Earth.

But what Lord Penzance overlooked, was that it was normal for gas to be formed in the reaction, because the reaction was so intense that it was easy to ignore the gas that was not originally intended.

In his paper, he described the alkaline solution of Kayla dissolved in water, which was capable of precipitating a substance that, in his view, was a compound of water and Kayla rather than that water had been broken down into two parts.

"After reading this paper, I began to make bold assumptions that there are two kinds of water that make up water, and at least one element with active properties, if you use the method of electrolysis, then you can get these two substances, and the logic should be no problem here, right?"

Reiner confirmed, and at this point Claire's eyes had more doubts, and the teacher nodded silently, not asking questions.

"Then, if in the experiment, the mass of water decreases and other substances with unique properties are formed, then it means that my hypothesis is true, water is not a basic element but a compound, and if it is the other way around, it means that my hypothesis is not true."

As he spoke, Reiner arranged the experimental equipment, pulled two wires from the electrolysis array, used as the positive and negative electrodes, and probed into the two test tubes filled with water and placed upside down in the sink.

"Ready, let's start experimenting, Mr. Claire."

Reiner gestured, causing Claire to slowly activate the electrolysis circle.
