These water droplets were not in the test tube before. Claire's identification method clearly told her the result, but after contacting the flame, water was produced in the test tube.

What does that mean?

"Can the combustion of this gas produce water?"

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

"I think we should make some more gases to verify their properties."

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

"Combustion supporting gas can be collected by drainage method, but it will be slightly soluble in water over time. It is colorless and tasteless, and has no obvious toxicity to human body. It can promote combustion or burn itself. The relative element mass of the elements constituting the gas comes from the electrolysis of water. The average value determined by the three methods is 16.3. It can be inferred that the gas is composed of atoms of two elements, I believe Name this element "oakles."

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

The academic definition of relative element mass is the ratio of one twelfth of the mass of target element and "Cabernet". The common form of "Cabernet" is black combustible solid, which is the main component of coal.

The magic of measuring the relative element mass can measure the molecular mass, Lennar can measure the relative element mass of two gases, and then the relative element mass of the element itself can be obtained by simple calculation according to the relative element mass of water.

Because these spells can't measure the relative mass of individual elements in the compound, it's difficult to find new materials. It seems that some mages are looking for a new method of measurement, but they don't have a clue yet.

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

After that, Lena did the same experiment with another gas.

"This kind of gas can be collected by the drainage method. After experiments, it is found that it is almost insoluble in water, colorless, tasteless, and has no obvious toxicity to human body. It is very easy to burn. After burning, water is generated. The relative element mass of the elements that make up the gas comes from the electrolysis of water. The average value determined by the three methods is 1. It can be inferred that the gas is composed of atoms of two elements. I name it" water " "Hedra."

Heidra is a monster once discovered by ancient mages in a half plane. More than 90% of that half plane is covered by sea water, and that monster is the overlord of the sea, which is also recorded in magic books.

"This element is really light in weight."

Charlotte sighed that the relative element mass of 1 means that the mass of a "Hydra" atom is one twelfth of that of a "Cabernet" atom. This light element actually has the name of a giant monster, which is indeed a kind of contrast.

Lena smiles, and does not explain the great power that this seemingly lightest element may produce in the future. He also conducts some experiments, mixing common combustibles with "oakles".

As expected, the product of the mixed combustion of "Cabernet" and "oakles" is the magical flame-retardant gas in coke, in which the constituent ratio of elements is 1:2. According to the nomenclature, Lena named this gas "Cabernet's double oakles compound". Because the common name of Cabernet is carbon, and the aqueous solution of this gas has a certain content So it's also called carbonic acid gas.

When "oakles" and "hedra" are put into a closed container according to the ratio of one to two and ignited by a spark, the mass of water obtained is exactly equal to the mass of the two gases put into the container. Experiments show that the mass of matter is conserved before and after the gold smelting reaction.

At this point, the experiment on the properties of gases is over, and Lerner wrote at the end of his notes.

"According to the experimental process, we can know that water is not a simple substance, but a compound of" oakles "and" Hydra "elements with a ratio of one to two. When it is electrified, it can decompose the gas elements of these two elements."

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

Modern alchemy system.

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

"Oakles" can promote combustion, but it does not have negative mass. It is not a fire element, but most combustion reactions need its participation. In the past, the core element of combustion that people could not find everywhere was "oakles".

The conclusion of conservation of mass overturns many popular reaction formulas in the past. People need to find other substances missing in the experiment to satisfy this law. All the alchemy textbooks will be rewritten!

Claire looked at Lena's notes. The beautiful script made the teacher more melancholy, just like a lost child who couldn't find his way home.

"Is everything wrong for hundreds of years?"

Murmuring to himself, Claire's eyes were lost.

At this time, a hand gently on her head.

"Not all of them are wrong. The theory of combustion and the theory of basic elements have a great influence, but many of the conclusions based on them will not be changed by new discoveries. Can't charcoal be burned after today? Of course not. "Lena gently stroked Claire's soft blonde hair, rubbing his fingertips against the ends of his hair, giving him a wonderful feeling.

"In fact, from today on, not only alchemy, but also the whole magic world will benefit from it. We overthrow the past theory, not to make the whole magic tower collapse, but to further the truth. It is even possible that in the future, these conclusions will be overturned by formulas that describe the world more accurately. We are just taking a step towards the truth. "

This simple step took 300 years.

Claire gently raised his head. The headmaster, who used to look very uncomfortable, seemed to be more gentle. His words echoed in Claire's ears. It was not a proud declaration, but a modest whisper.

There is no arrogance, no complacency. What Leiner shows is only the heart of exploration.

Herman Braggs, the legendary mage who stood out in the ancient magic war and established the modern magic system, once said that the so-called mage is just a person who seeks the truth. At this moment, Lena's words and deeds are the most true portrayal of this sentence.

Looking at her face, Claire felt some heat on her cheek. She quickly turned away from her head and covered her hot cheek with her hand.

The heart beats fast. Even in the fifth magic test after four losses, Claire has never felt like this. This is different from tension, but a more pure emotion.

"Well, Mr. Claire..."

Lena looked at Claire and said softly.

"Can you help me organize today's experiment notes so that I can write my thesis?"

"Ah?"

The turn of the words was a little strange. Claire didn't react to it for a moment, but when she realized her gaffe and Lena's indifferent attitude, the teacher felt resentful.

This guy is really bad!
