The droplets weren't in the test tube before, and Claire's identification clearly told her the result, but after coming into contact with the flames, water was produced in the test tube.

What does this mean?

"The combustion of this gas can produce water?"

Charlotte said this conclusion that Claire did not dare to confirm, but it was obviously easy to see.

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

Reiner didn't affirm or deny, but continued to fiddle with the lab apparatus and collected enough of the two gases.

"Combustible gas can be collected using the drainage method, but over time it will be slightly soluble in water, colorless, odorless, has no obvious toxicity to the human body, can promote combustion or can burn itself, from the electrolysis of water, the relative elemental mass of the elements that make up the gas is determined by the three methods to be 16.3, it can be speculated that the gas is composed of atoms of two elements, and I named this element 'Ocles'."

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

The academic definition of the relative elemental mass is the ratio of the target element to one-twelfth of the mass of the element "Carborne", a common form of the element "Carborne", which is a black combustible solid, which is the main component of coal.

The spell for determining the relative elemental mass can measure the mass of the molecule, Reiner measures the relative elemental mass of two gases, and then according to the relative elemental mass of the composer compared to the control water, the relative elemental mass of the element itself can be obtained after a simple calculation.

Since these spells cannot measure the relative elemental mass of the individual elements in a compound, it is difficult to find new substances, and it seems that there are mages who are looking for a new way to measure them, but have no clue.

As for the nomenclature, it follows the habits of alchemists, found in an ancient magic book.

After writing this, Reiner took another gas and did the same experiment.

"This gas can be collected by drainage, and after experiments it was found that it is almost insoluble in water, colorless, tasteless, has no obvious toxicity to the human body, is extremely flammable, produces water after combustion, electrolysis from water, and the relative elemental mass of the elements that make up the gas is determined by the average value of the three methods to be 1, and it can be speculated that the gas is composed of atoms of two elements, and I named it 'Hydra'."

Hydra is a monster once discovered by ancient mages in a half-plane, more than ninety percent of that half-plane is covered by sea, and that monster is the overlord of the sea, which is also recorded in the magic books.

"It's so lightweight."

Xia Luo sighed with emotion that a relative elemental mass of 1 means that the mass of a "Hydra" atom is one-twelfth of that of the "Carborne" atom, and this light element actually has the name of a huge monster, which is indeed some kind of contrast.

Reiner smiled, not explaining the immense power that this seemingly lightest element might bring, and conducted some experiments to mix common combustibles with "Ocles".

As expected, the product of the mixed combustion of "Carbon" and "Aucles" is the magical flame-retardant gas in Cola, in which the elemental composition ratio is one to two, Reiner named this gas according to the nomenclature "Carbon's double Ocles", because the common name of the Carbonne element is carbon, and the aqueous solution of this gas has a certain acidity, so it is also called carbonic acid gas.

When "Ocles" and "Hydra" are placed in a closed container in a ratio of one to two, the mass of water obtained after ignition with a spark is exactly equal to the mass of these two gases in the container, and experiments have proved that the mass of the substance is conserved before and after the alchemical reaction.

At this point, the experiment on the properties of the gas came to an end, Reiner wrote at the end of his note.

"According to the experimental process, it can be seen that water is not an elemental substance, but a compound obtained by the elements 'Ocles' and 'Hydra' in one to two, and in the case of electricity, it can decompose the gas element of these two elements."

This sentence seems simple, but it overthrows a whole system.

Modern alchemy system.

The electrolysis of water shows that the so-called "basic elements" are not fundamental, and that matter is not made up of these four elements.

"Ocles" can promote combustion, but does not have a negative mass, it is not a fire element, but most of the combustion reactions need its participation, the core element of combustion that people have not found in the past, is "Ocles".

And the conclusion of conservation of mass is to overturn many reaction formulas that have been deeply rooted in the hearts of the people in the past, and people need to find other substances that have been omitted to collect in experiments to satisfy this law, and all alchemical textbooks will be rewritten!

Claire looked at Reiner's notes, and the beautiful floral font made the teacher even more melancholy, like a lost child who couldn't find his way home.

"Is everything wrong for hundreds of years?"

Muttering to herself, Claire's eyes glazed.

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

"Not everything is wrong, the theory of combustion and the theory of the basic elements have a great influence, but many of the conclusions on this will not be changed by new discoveries, so can't charcoal burn from today onwards? Of course not. ”

Reiner gently stroked Claire's smooth blonde hair, rubbing his fingertips against the ends of his hair, giving him a wonderful feeling.

"In fact, from this day forward, not only alchemy, but the entire wizarding world will benefit from it, and we will overturn the theories of the past, not so that the entire magical tower will collapse, but in order to move closer to the truth. It is even possible that in the future, these conclusions will be overturned by formulas that describe the world more precisely, and we are only taking a small step closer to the truth. ”

It took three hundred years to take this simple step.

Claire raised her head slightly, and the headmaster, who had not looked good at all, seemed to be much softer, and his words echoed in Claire's ears, not a declaration of pride, but a humble whisper.

There is no arrogance, no pride, what Reiner shows is only the heart of inquiry.

Herman, a legendary mage who stood out in the ancient magic wars and single-handedly established the modern magic system. Braggs once said that the so-called mage is just a person who seeks the truth, and at this moment, Reiner's words and deeds are the truest portrayal of this sentence.

Claire felt some heat on her cheeks, and she hurriedly turned her head away and covered her hot cheeks with her hands.

Her heart was beating fast, and even in the fifth magic test after four defeats, Claire had never felt it this way, it was not nervous, but something more pure emotion.

"So, Miss Claire......"

Reiner looked at Claire and spoke softly.

"Can you help me organize my lab notes for today so I can write my paper?"

"Huh?"

Claire didn't react for a moment when she realized her gaffe and Reina's careless attitude, and the teacher felt a little resentful in her heart.

This guy is really bad!
