Greetings, Mister Principal

These water drops were not in the test tube before. Claire's Appraisal Spell clearly told her this result, but after contact with the flame, water was produced in the test tube.

So, what did this mean?

"The combustion of this gas can produce water?"

Sharon made the conclusion that Claire did not dare to confirm, but they could obviously see the result.

"I think we should make some more gas to verify its properties."

Reiner did not affirm or deny, but continued to fiddle with the experimental equipment and collected enough two gases.

"The combustion-supporting gas can be collected by the drainage method, but it will be slightly soluble in water over time. It is colorless, odorless, and has no obvious toxicity to the human body. It can support combustion or can burn itself, and it comes from the electrolysis of water. The average of the relative elemental masses of the elements that make up the gas is 16.3, which was determined by using three methods. It can be speculated that the gas is composed of atoms of two elements. I named this element ‘Occles'."

After conducting a series of experiments, Reiner wrote this description in his notes.

The definition of relative element mass in academia was the ratio of the target element to the one-twelfth of the element mass of "Carbone". The common form of "Carbone" was a black combustible solid substance, which was the main component of coal.

The relative element mass measurement spell could measure the mass of the molecule. Reiner measured the relative element mass of the two gases. Then, based on the relative element mass of the water, the relative element mass of the element itself could be obtained by a simple calculation.

Since these spells couldn't measure the relative element mass of individual elements in the compound, so it was difficult to find new substances. It seemed that some mages were looking for new measurement methods, but they had no clue.

As for the naming rule, he followed the habits of alchemists, which he found from an ancient magic book.

After writing these, Reiner carried out the same experiment with another gas.

"This gas can be collected by the drainage method. It is found through experiments that it is almost insoluble in water. It is colorless, odorless, and has no obvious toxicity to the human body. It is very easy to burn. After burning, it generates water. The average value of the mass measured by three methods is 1. It can be inferred that the gas is composed of atoms of two elements. I named it 'Hydra'."

Hydra was a monster once discovered by ancient mages in one demiplane. More than 90% of that demiplane was covered by sea water, and that monster was the overlord of the sea and was also recorded in the magic books.

"The quality of this element is really light."

Sharon sighed with emotion. A relative element mass of 1 meant that the mass of a "Hydra" atom was one-twelfth that of a "Carborne" atom. But this light element actually had the name of a giant monster. It was such a huge contrast.

Rainer smiled, and did not explain the enormous power that this seemingly lightest element might conceive in the future. He then conducted some experiments to mix common combustibles with "Occles".

Unsurprisingly, the product of the mixed combustion of "Carborne" and "Occles" was the kind of magical flame-retardant gas in Cola. The element composition ratio was one to two. This gas was named "Carbone Double Occles". Because the common name of the Carbone element was carbon, and the aqueous solution of this gas was acidic. It was also called carbonic acid gas.

When "Occles" and "Hydra" were put into a closed container at a ratio of one to two, the mass of water obtained after ignition with a spark was exactly equal to the mass of the two gases put in the container. Experiments had proved that the mass of matter was conserved after the alchemical reaction.

At this point, the experiment on the properties of the gas came to an end. To finish the note, Reiner wrote:

"According to the experimental process, it can be known that water is not a simple substance, but a compound obtained from the elements of 'Occles' and 'Hydra' in a ratio of one to two. When electricity is applied, the gas of these two elements can be obtained."

This sentence seemed simple, but it overthrew an entire system.

Modern alchemy system.

The electrolysis of water showed that the so-called "basic elements" were not basic, and the matter was not composed of these four elements.

"Occles" could support combustion, but it did not have a negative mass. It was not a fire element, but most of the combustion reactions require its participation. In the past, the core element of combustion that people could not find was "Occles".

And the conclusion of conservation of mass overturns many of the previously well-established reaction formulas. People would need to find other materials that had been missed in the previous experiment to meet this law, and all alchemy textbooks would be rewritten!

Claire looked at Reiner's notes. The beautiful swashes made this Professor feel even more melancholy, like a lost child who could not find her way home.

"Have we been wrong for hundreds of years?"

Muttering to herself, Claire's eyes were blank.

At this time, a hand was gently placed on her head.

"Not everything is wrong. Combustion theory and basic element theories have a great influence, but many conclusions on this will not change because of new discoveries. Do you think charcoal would not burn after I publish this? Of course not."

Reiner gently stroked Claire's soft blonde hair, his fingertips moving gently against her smooth hair. It was a wonderful feeling.

"In fact, starting from today, not only alchemy, but the entire magical world will benefit from it. We overturn the past theories not to collapse the entire magical tower, but to move further toward the truth. It is even possible that in the future, these conclusions will be overturned by formulas that describe the world more accurately. We just made a little step forward in the process of approaching the truth."

This simple step took three hundred years.

Claire lifted her head slightly. The principal, who had never looked pleasing to her eyes in the past, seemed to have become a lot more gentle. His words echoed in Claire's ears. It was not a proud declaration, but a humble whisper.

There was no arrogance, no complacency, what Reiner showed was only the heart of exploration.

The legendary mage Hermann Braggs, who stood out in the ancient magic wars and established the modern magic system single-handled, once said that the so-called mage was just a person who sought truth. At this moment, Reiner's words and deeds were precisely this. The truest portrayal of the sentence.

Staring at him, Claire felt a little hot on her cheeks, she hurriedly turned her head away, and covered her hot cheeks with her hands.

Her heartbeat was beating fast. Even in the fifth magic test after four failures, Claire had never felt this way. It was different from tension, but a purer emotion.

"Then Professor Claire..."

Reiner looked at Claire and said softly.

"Can you help me sort out today's lab notes so that I can write the paper?"

"What?"

The turn of the words was a bit strange, Claire didn't react for a while, but when she noticed her gaffe and Reiner's indifferent attitude, the Professor suddenly felt a little resentful.

This guy was terrible!
