"Could it be that what Lord [Element Master] Artok said is right, and the elements can be further divided?"

Dennis couldn't help but frown. The current mainstream theory in the wizarding land tends to be that [elements are indivisible and are the basis for building the world]. Because this is the limit of [matter deconstruction], they can no longer decompose the basic elements.

The legendary Speaker Artok did propose a theory of element redistribution, but he suddenly went crazy before he found any evidence. The notes he wrote also created the Doomsday Cult, a group of crazy people who believed that the world was about to end, so it only existed as an unreliable hypothesis.

"Of course!" Lin En nodded. "According to the hypothesis of some scholars in the [Secret Law Society], elements are composed of atomic nuclei and electrons orbiting the nuclei."

Dennis was very interested in this topic and immediately asked what the so-called atomic nucleus and electrons were.

Lin En did not give too much explanation, and said that this was just a magic theory that needed to be proven by relevant experiments.

Although there are models of more than one hundred elements in the database of the intelligent computer, Lin En can now confirm that only the model of plutonium is most likely correct. More importantly, Dennis, who has never been exposed to quantum theory before, may find it difficult to understand the structure and operation of an atom.

After all, wizards believe that "the whole world is running according to certain laws, and wizards perform magic by understanding and applying these laws." He even suspected that the legendary Speaker, who was known as the "Master of Elements," had already come into contact with the microscopic realm, and suddenly went crazy because he could not accept the characteristics of quantum.

"Dean, the aerospace airship returning from the Kingdom of Hadrata has arrived." Several apprentices walked in from outside and bowed to report to Lin En.

"It looks like our guests are here!" A smile appeared on Lin En's face. "Let's go out and take a look."

…

At the same time, a huge airship passed through the heavy fog, arrived above the port city, and slowly landed on a specially expanded site.

"Is this the land of wizards? I didn't expect there is such a prosperous place on the other side of the sea..." Fulla followed Orlando and others down the airship, looking around constantly.

Everything that this port city presented was new to Fulla. It was completely different from any city in the Kingdom of Hadrata, and even the most prosperous royal capital could not compare to it.

In fact, except for the main urban area, the entire royal capital is dirty and messy, and usually has a bad stench.

After living there for a long time, Fulla didn't think there was anything wrong, but after arriving in Yieta, she discovered that a city could be so clean and tidy.

And in just a short while, she had already seen seven airships flying over the city. In addition to the common horse-drawn carriages on the streets, there was also a very strange iron box that could run very fast without being pushed or pulled by camels or horses.

White smoke was belching out of the chimneys of the workshops in the distance. Such smoke could never be seen in the Kingdom of Hadrata.

The entire giant ship is fifty meters high and over a hundred meters long. There are rows of ferocious gun muzzles on both sides of the ship, standing on the dock and extremely conspicuous, like a moving island.

"These are the battleships that are being built, and they are made entirely of steel!" Orlando introduced them to everyone proudly. Although he had not been back to Yieta for some time, these battleships already had a general framework before he left, so it was naturally not surprising.

"Can a ship made of steel float on the water?" Ham asked in astonishment.

Even Anthony was quite interested. Could it be that someone had cast some powerful magic on this huge steel ship? But such a large ship must weigh hundreds of tons, and the amount of magic power consumed must be incalculable.

"Of course!" Orlando said proudly. "The dean said that the reason an object floats on the water is because the gravity it receives is less than the buoyancy of the water..."

Orlando used the knowledge he learned from Lynn to explain the laws of mechanics to everyone present - an object immersed in a stationary fluid is subject to a buoyant force equal to the weight of the fluid displaced by the object.

So we just need to use the formula, dividing mass by volume to calculate the density. As long as it is smaller than water, it will naturally float. For example, the bottom cabin of their steel battleship is actually hollow, so the part that sinks to the bottom of the water has an overall density much smaller than water.

"As long as this condition is met, anything can float on the water. Dean Lin En has also invented a new word, called displacement! It is the tonnage of water displaced by the ship in the water..." Orlando introduced it in a torrent of words. "We will build a few more ships like this, and then we can bring back enough sea fish to feed tens of thousands of people for a whole week on a single voyage!"

Fishing?! Everyone present was a little slow to react. They had just been listening to Orlando bragging about how powerful this huge steel ship was, but now he told them that this thing was used for fishing. It was a little hard for them to accept it for a while.

Orlando curled his lips. In fact, he also felt that this was a waste of talent, but Dean Lin En obviously did not think so.

According to Lin En, since it has been built, it cannot be left idle when there is no war. Using it for fishing can not only create benefits and improve the townspeople's diet, but maybe they can also kill a few sea beasts for the gunners to practice their accuracy.

Unlike Fulla and the others, Raeder did not focus on the towering ironclad ship, but on the poor people passing by. Everyone was dressed appropriately. Such beautiful clothes were usually only affordable by the nobles, but now they were worn by the boatmen transporting goods...

"How could they bear to wear such beautiful clothes while moving goods? What if they get torn?" Ham said with great concern.

Orlando responded with a smile. "This is nothing in Yieta. Every day, the workers in the magic workshop can produce tens of thousands of meters of cloth. Here, you can buy a decent set of clothes with just five copper coins."
