Closing the diary, Reiner breathed a long sigh of relief, he didn't expect Fina's father to have such a secret.

He hesitated, not knowing whether to tell Fina these things.

Reiner was able to understand Fina's father's thoughts a little, he didn't want Fina to be treated differently from an early age, and wanted her to grow up like a normal child, but to be honest, Sur Town was not a suitable place.

Fina persevered and eventually became a calm mage apprentice, but maybe a different person would go crazy in such an environment, sink, and even start to take revenge on society.

Shaking his head, Reiner glanced at the back of the diary again, which was mostly notes about experiments, and Fina's father's own life was very rare, except for occasional letters from Fina, which would take up a lot of space in the diary.

Reiner perused the contents of his lab notes, but the more he looked at them, the more shocking he became.

During the decade when magic was unavailable, Fina's father made a mathematical deduction of the relationship between magnetic and electric fields, and he almost succeeded!

Fina's father came up with four formulas, one by one for Sarri. Lord Newington and Clark. The four equations summed up by His Excellency Holland are just a pity that because he can only calculate them on paper, and he has not obtained the latest academic advice in time, some phenomena and conclusions are still stuck in the mistakes of more than ten years ago, so the four formulas have different degrees of errors.

Naturally, Reiner guessed, nor did it cause any feedback from the world.

But the form of these four formulas is very close to the Newington-Holland equation, and it is exactly seven years before the two of them came up with it!

The equations obtained by the two high-level mages using the most sophisticated instruments and the most powerful calculation arrays, Fina's father completed the approximation seven years ago with just a simple pen calculation, which is incredible!

Reflecting on the contents of the diary, Reiner was shocked to realize that the Clark who often appeared in the diary was Clark. Holland?

Fina's father and the seven-ring high mage Clark. Holland was once a classmate? And judging from the account, his achievements are on par with His Excellency Holland?

As we all know, Clark. Holland is extremely talented, after graduating from the Rainbow Tower's High School of Magic, he was favored by high-level mages, and was able to work at Newington Institute, and in the following years, he continued to rise at a rate of one order almost every year, and is now a seven-ring high-level mage.

And Fina's father, who is on the same level as His Excellency Holland, if he hadn't been forced to give up his studies for these regrettable reasons, today's achievements would not be on par with His Excellency Holland, but at least he would have become a mage above the middle level.

But now, this man, who once targeted as a high-level mage, chose to live in seclusion in the mountains and forests for the sake of his daughter, and finally turned into ashes in the flames.

Reiner sighed.

On Earth, he himself had the hope of continuing his education, but because of his father's serious illness, he had to choose to work as a secondary school teacher in a remote hometown.

Thinking of this, Reiner had already made a decision, he could not let Fina's father be buried in this ignorant and backward town, at least, to let the world know that there was once a mage, at the foot of this desolate and lonely mountain, but he took a solid step towards the distant world.

Reiner continued to dig through the pages to find more research on Fina's father, and he discovered that since Fina left for Crescent Academy, Fina's father had been conducting some basic experiments to find a cure for Fina's strange illness.

Based on his flawed four equations, he devised magic and experimented with everything he could come into contact with.

Most of the magic related to electromagnetism requires a magic level of more than five orders to be cast, and Fina's father has no plan to continue learning, and the magic level only stays in the second ring, but he has a wealth of mathematical knowledge about the structure of the magic circle, and he has successfully made an electromagnetic magic circle powered by standard magic stones that can also be used by low-level mages by a little bit of his own attempt.

The next experiment may have been an accident, as Fina's father used a homemade electromagnetic circle to speed up some particles that had been found to be charged, but accidentally collided with another particle, resulting in a mixture of the two particles.

Originally, the experiment should have ended in failure, but Fina's father found that the mixed particles continued to move under the acceleration of the electromagnetic field, and left three traces on the receiving board as the target!

The magic on the receiving board can produce feedback on charged particles or rays, revealing traces, two of which are supposed to be the original trajectories of the two particles, while the third one cannot be explained, and Fina's father has obtained the ratio of the charge charge of the particles represented by this new trajectory to their masses through careful actuarial calculations.

Unfortunately, Fina's father made a major error in his calculations due to the error in the four equations for describing the electromagnetic field, and he initially thought it was a new element, but its mass was so small that it seemed difficult to separate unless two particles collided in an electromagnetic circle, so he simply called it a "negatively charged particle".

Soon, Fina's father found a way to stabilize the production of this negatively charged particle, which he used to repeat the experiment at the time, and found that the impact of this particle could cause some otherwise uncharged particles to deflect in the electromagnetic circle.

Fina's father conducted several experiments, and he found that the masses of these elements, which were inversely deduced from several equations he had derived, were exactly the masses of the elements that had been measured.

But there are exceptions.

He measured and found that there were several elements that had more than one trace after impact.

For example, Knightron, a gaseous element that is considered phlogiston-saturated air in phlogiston theory, has been processed by Fina's father's magic circle, and there are two traces of similar distance and one trace of a little further away.

Fina's father first studied the particles represented by the two traces at a similar distance, and found that the properties of the two elemental particles were almost identical, only the masses were different, and he thought that this might be an error in the experiment, and he had not had time to verify it experimentally.

But the elemental particles represented by the other, a little farther away, in Fina's father's research, showed completely different properties from the Knightron element.

This element is a gas, colorless and odorless, not prone to alchemical reactions of various substances, denser than air, and in the case of electricity, it shows a purple-red glow.

This is most likely a completely new element!
