The disadvantages have been said so much, but the advantages cannot be ignored.

Over the past twelve years, with the support of Falkenridge, the materialism has ushered in a rare period of prosperity.

Although only about 50 members have officially joined the Heliographic Society, not even some of the smaller magical societies, there is a reason for this: at present, due to the severe exclusion of the material school, many scholars are actually unable to enjoy academic freedom.

For example, some extremists of the School of Magic threaten those who have published significant results, as happened to Epstein. And not all of the materialist scholars were as alone as Apstein and had martial arts protection—many of them had families.

Therefore, under a series of entanglements, they will never hesitate to join the Helio-Solar Society, which is considered a "heretical" gathering place in the mainstream academic world, as Epstein did.

Fortunately, with the efforts of Ailo and others, the influence of the Solar Optical Society has been rising for more than ten years, so that now, although there are not many people who have actually joined the Society, the number of people who admire it is far more than a thousand, not to mention that a small half of them continue to exchange experiences with the members of the Society through various indirect channels.

All in all, the Solar Optics Society currently has a large number of potential members, and the number of these potential members is constantly increasing. Just wait until the time comes, and they will be transformed into real members.

And at that time...... That is, when the dawn of the materialistic school came.

What makes Iroh even more satisfied is that the influence of the Solar Optics Society has not only increased year by year, but it has even really contributed some actual research results.

Chief among them is the theory Humphrey once mentioned.

To be precise, the theory twelve years ago was just a conjecture. But even so, even Iello had to admire the wisdom of this group of scholars—Humphrey spent twenty years coming up with a conjecture with almost no research resources, and then spent twelve years with Turner, Young, and others refining it into a set of theories.

This theory can be summarized as follows: matter and energy can be converted into each other.

Yes, it was when Iroh learned of this theory, which was still in a state of conjecture, that he decided to recruit Humphrey into the Helio-Optical Society.

If you think about it, isn't Iroh's current greatest weapon, the ability to cause a terrifying explosion, actually in line with this theory?

The particles of matter, which were originally unremarkable, were cracked under the action of a wonderful flow of light, and then burst out with an incomparably huge amount of energy......

Twelve years of research has also proved the correctness of Ayellau's prediction: Noele's reconstruction of the ancient ruins records shows that the people of the last era were indeed using two main methods to create that powerful weapon, one of which is "nuclear fission" and the other is "nuclear fusion".

There is still no specific description of what nuclear fusion is, but the relevant claims of nuclear fission have already been found.

To put it simply, only some very large particles of matter, such as the previously mentioned uranium, can undergo nuclear fission. After absorbing one neutron, it splits into two or more particles of matter with a smaller mass, and at the same time releases a huge amount of energy, which can cause other particles of matter to continue nuclear fission......

This process continues, and it is a chain reaction.

This scene was exactly the same as everything that Iroh's spiritual power had witnessed when he entered that strange space!

Incidentally, in the last epoch, this particle of matter had another, more understandable name, called "atomic nucleus".

In addition, the 12 years of almost completely free research environment has also allowed many academic theories that have been suppressed to develop explosively.

Under the indirect leadership of Noele, a pure scholar, the members of the Solar Optics Society can be said to have transformed the savings of their predecessors into tangible research results.

In fact, before Humphrey's theory was perfected, the Helio-Optics Society also discovered two seemingly ordinary laws, but it was these two laws that allowed Humphrey to finally dispel his long-standing confusion and formalize his conjecture as a theory.

One of them was discovered by the seemingly vicious tiger orc alchemist.

Through a large number of experiments, he and his companions found that in all the alchemy processes, the sum of the masses of the substances participating in the reaction is equal to the sum of the masses of the substances produced after the reaction.

After much verification, they called this law the law of the immortality of matter.

In other words, in a system that is isolated from its surroundings, its total mass remains the same, regardless of its changes or processes. In other words, no change can eliminate matter, but only change the original form or structure of matter.

The other law was discovered by an alchemist who had only joined the Helio-Optics Society ten years earlier.

This is actually due to the policy of integration between the two factions advocated by Iroh, as the scholar was originally dedicated to the study of fire magic, which is also a member of the school of magic. Later, however, as the exchange with the Japanese Optical Society deepened, he gradually realized the commonalities between the two schools.

After a period of hesitation, it was the thirst for truth that suppressed the views of the school, and he decisively joined the Helio-Optical Society, combining their ideas for his own research.

Until three years ago, he succeeded.

He believed that the essence of flame was an intuitive manifestation of heat, or energy. Whereas, heat is nothing more than a motive force and can also be seen as a movement in the form of material transformation. For a substance, if there is a disappearance of the motive force, then at the same time there must be heat that is strictly proportional to the disappearance of the motive force.

On the contrary, where the heat disappears, there is bound to be momentum. Therefore, it can be conjectured that the amount of power is constant in nature, and more precisely, the amount of power can neither be generated nor destroyed.

With a little generalization, it is easy to know that since the kinetic force is constant, then the energy in this world is also constant.

This discovery is aptly called the Law of Immortality of Energy.

It was under the inspiration of these two laws that Humphrey completed the final deduction of his theory.

Since the total amount of matter and energy is constant, the many changes in matter witnessed in daily life are essentially a process of mass and energy transformation. The reduced matter does not disappear, but becomes energy. In the same way, the reduced energy did not disappear, but became matter.

In other words, matter and energy have the same essence. In other words, matter is a manifestation of energy!

And that's not all, the half-elf further pointed out that, for the above reasons, any object with mass must store invisible energy, and this energy stored by mass is unimaginably large.

This was the heart of the previous theory that Turner had been hard to believe: that the energy of change is equal to the amount of matter that changes multiplied by a huge constant.

It's a pity that Humphrey still can't be sure what this huge constant is, but he is very sure that it is definitely a number that is unimaginable to normal people, I am afraid that it is more than 100 million.

Iroh agrees with this, and the two explosions he himself caused have confirmed this theory from some point of view.

To sum up, Airo believes that as long as the research of the Helio-Optical Society continues, the day when he can truly master the power in his body will not be too far away.

Of course, having said all this, in fact, it is only a reluctantly summary of the changes in the helio-optical society.

Twelve years is not a short time for ordinary people, and the changes in the Icourt Valley will definitely not be limited to this.

Thinking like this, Iroh stretched out and slowly walked out of the castle hall in the form of a human boy.

He also had to admit that this feeling of watching his power develop day by day was really not bad.

The valley that used to be peaceful has almost changed dramatically now, and the center of the valley has not changed much in order to maintain respect for the lord, but other places are different.

In the southern part of the valley, the former town of Hope has been renamed Hope City. The town originally founded by the goblins grew rapidly during the twelve years of peace that Iroh had secured, bringing together nearly all the goblins in Falkenridge and expanding further with the help of the Church of the Dragon.

It's like a growing monster, absorbing all the nutrients it can find and transforming it into its own body.

In addition to the size of the area occupied by today's Hope City, it is almost comparable to the royal capital of Barrington back then.

The original goblin leader, Raja, had reached his old age and was barely able to run around like he used to, but in his current capacity, he really didn't need to do that kind of thing.

As the high-ranking Grand Imam of the Yanlong Church and the current supreme head of the Church, Raja only needs to sit in his golden mansion in the center of Hope City, listen to the reports of his subordinates, and make decisions.

Near Raja's home is the wealthy area of Hope City. Goblins who followed Raja, businessmen who saw Falkenridge's future potential, and scholars from the Heliographic Society often bought a house in the area.

The northeastern part of the wealthy area is a civilian area, and in addition to the vast majority of ordinary subjects, there are also some Japanese optical societies, and even scholars from outside the academy will come here to impart some knowledge and skills, which is naturally promoted by Iroh.

As a long-lived dragon, Iroh knew that these scholars could not live as long as he did, and that research could not be wasted after the scholars died. This dictates that the knowledge held by scholars must be passed on, and even if not all of it is passed on, most of it must not be lost with their death.

Immediately to the south of the wealthy area is where the Solar Optics Society is located. As one of the most important places in the city, there are a lot of protective measures arranged around the Solar Optical Society, after all, many of the research of the Solar Optical Society is related to the power of Iro, and even the strength of Iroh itself.

The last thing we can't fail to mention is the southeast of the city. Although it is the least important compared to other places, it is also indispensable. Because the city's circulation system and basic service facilities are basically concentrated in this area, it is precisely because of this area that Hope City stands out from the many cities in Falkenridge and has become a new and prosperous city.
