Begania and the three of them walked through the castle complex, visiting every corner, and in addition to the construction of the exterior buildings, they also carried out the interior decoration.

The library and dormitory buildings are made of wood from the fairy country, and the dark brown wood is used, which is visually deep and heavy, and more in line with the mystery of the magician.

"Honestly, you're more comfortable than Hogwarts."

After visiting the school, Tony said directly to Char.

Char's school is much larger than Hogwarts, and it has more infrastructure.

"You'll live here in the future." Char said, "I've reserved a lab space for you, which is very hidden, and the door to enter can appear anywhere in the school. ”

"Similar to a Room of Requirement?"

Char nodded, "Interested in becoming a teacher?" ”

"What can I teach, science?" Tony asked rhetorically, "In the context of this world, there is no real scientific enlightenment, and I have to start teaching with multiplication tables." ”

"Indeed, it's too cheap for you." Char said.

"How about the store for me?" Tony said.

Char raised her eyebrows, "You really want to sell brooms?" ”

"Can't you?" Tony grinned, "It's time to bring some tech to the wizarding world, and you can run a big air racing event at the school in the future, which is much more exciting than Quidditch." ”

"It looks like we're going to have to legislate in schools in the future, and don't run brooms inside schools." Char muttered softly.

"Do you have any other requirements?" Baigania asked from the side.

Char shook his head, "I'm satisfied, thank you, Baigania. He is truly the designer of the White City. ”

"No thanks, it's an achievement for me." Baigania said with a ruddy face.

"If you're satisfied, then there's only the most critical step left."

After a pause, Baigania continued, "I have asked the best craftsmen among the dwarves to make the drawings and data you have given you, little by little. ”

Char nodded, "Take us to see it." ”

Then, Baigania led them through an inside-designed secret passage into the underground of the castle, an octagonal mysterious space.

Because it was built under a giant tree called Arvac, it was clear that several thick roots were visible in the space that became the beams of the underground space.

But the most eye-catching thing is the prototype device in the middle of the space that shimmers against the firelight.

At first glance, it looks like a scaled-down version of a planetary engine, and an enlarged version of the Iron Man energy device.

The device is circular in the middle, about three or four meters in diameter, and is spliced together by tens of thousands of parts, but each device looks like a creation from the future.

Seeing this, Tony immediately stepped forward and used the tools he was carrying to inspect some of the parts on it, which the dwarf had made based on his blueprints, so it was obvious that he wanted to have more say.

After about an hour, he slowly got up, with a little exclamation on his face, "It's incredible." ”

"How?" Char said.

"If you hadn't told me in advance, I wouldn't have believed that this thing was hammered out with a hammer." Tony muttered softly.

"Of course, the exact part can't be hammered out with a hammer alone." Begania stood in front of the device with his hands behind his back.

"However, alchemy can do it, and the fineness of the mind can be perfect, and you only need to ask the dwarves to create a rough shape, and then use alchemy to refine it, and you can process such a thing.

Your requirements, high temperature resistance, low temperature resistance and corrosion resistance, etc., we have mixed a lot of Mithril in the original metal, which should be able to meet your requirements perfectly. ”

Tony came back to his senses, he looked at the device and whispered to Char beside him, "You're right, this is indeed one. A completely different civilization.

It's not lagging behind, it's just, it behaves differently. ”

He looked at Char.

Char raised his hand, and a bunch of machinery and materials were placed on Tony's side, which were some simple exoskeleton robotic arms and other things, all of which were made by Tony himself, and Char helped process some fine materials.

The concept of nuclear fusion is actually quite simple.

Everything in this world is basically made up of atoms.

Nuclear fusion, in which the cores of two atoms collide and merge, will emit a large amount of energy.

However, the nuclei of atoms have a repulsive force similar to that of magnets of the same sex, so it is necessary to make them active and increase the probability of collision.

And to make them active, you have to use high temperature and high pressure.

The heavier the element, the more difficult it is to fuse, and conversely, the lighter the element, the simpler.

But even for the lightest element, the fusion temperature to be reached is more than 100 million degrees.

In fact, a few thousand degrees of heat is enough to melt everything known to man.

But if realized, it would be enough to have almost unlimited energy.

Because the element deuterium needed for thermonuclear fusion is found in seawater, theoretically, according to the demand for human energy use in the 21st century, it can supply mankind to burn for 90 billion years!

Of course, this is only calculated in terms of the reserves of deuterium alone.

In fact, thermonuclear fusion requires the reaction of two elements to achieve, and deuterium-deuterium fusion rarely releases energy, which is difficult to sustain and should be difficult. And it doesn't make sense.

The relatively simple achievable is the first generation of thermonuclear fusion, which uses tritium, one of the isotopes of hydrogen, to fuse with deuterium.

The average market price of 1g tritium in 2003 was not less than 300,000 US dollars, and the actual international trading price was about 100~2 million US dollars/g, and the black market trading price added a 0.

However, the good news is that tritium can be artificially produced, and tritium can be produced by bombarding lithium with neutrons, and the production of lithium on Earth is quite large.

And after the fusion of tritium-deuterium, the atoms will produce a large number of neutrons, which is enough to produce cycles.

And Tony's cold nuclear fusion is carried out on the basis of this theory.

Cold nuclear fusion, as the name suggests, is nuclear fusion at low temperatures.

This method of fusion is safer and more controllable.

Nuclear fusion requires high temperature and high pressure, and the essence is to allow the atomic nucleus to break through the repulsion and combine to emit energy.

But if . What about another way to combine two nuclei?

For example, if two nuclei are forcibly squeezed into a small space that cannot accommodate two nuclei, is it possible for the two to coalesce?

Cold nuclear fusion is the technology of this concept, and the lattice of palladium is very suitable for this small space.

In Char's previous life, this technique had already proven to be a pseudoscience.

But Char has already embodied this technology in Tony's mind with the power of fate, and it is one of the few science fiction technologies he has embodied.

However, Char is not very clear about the specific operation.

Tony also has Char's destiny power in him, and if he recovers it, he may be able to have this part of the knowledge.

The most difficult part of cold nuclear fusion is how to put the nucleus into the lattice of palladium, and Tony seems to use some kind of chemical method.

But all in all, after a bunch of operations that Char couldn't understand, the center of the device began to light up with a dazzling blue light.

At the same time, the circle under their feet also began to light up, and the lines of the circle were depicted little by little.

This means that the cold nuclear fusion device in front of him has begun to fuse, and the energy released by the combination of atomic nuclei is being converted into magic by the magic circle and escaping in this space.

Feeling the magic power in the air, Char nodded, "It seems that it is indeed feasible to use the magic circle to transform the magic power. ”

"The sun is a super-giant nuclear fusion variant." Tony said, "Since this circle can transform sunlight, there is no reason why it can't transform the energy emitted by nuclear fusion.

However, "

There was a glimmer of light in his eyes, "What is the energy conversion rate of this magic circle, and how much is the loss?" ”

"It's up to you to do your own research." Char said.

Tony nodded, "Give me some time, and I'll see if I can formulate this process, so that we can build the size of the fusion device according to the formula, and maybe the energy loss can be minimized." ”

After a pause, he thought for a moment and said, "We have to get a computer first, without computers, without artificial intelligence, if the complex and tedious calculus work only relies on the human brain, the difficulty of various studies will increase exponentially." ”

"I think you can learn alchemy from the elves first." Char said, "It's very helpful in your work.

It allows you to cross the huge industrial system and have the ability to make high-definition parts yourself. ”

Char, after obtaining Howl's fate, also gained a certain degree of knowledge of alchemy.

Although Howl's Moving Castle is a fantasy work of another world, after manifesting in this world, it is natural to extend the original framework and knowledge of this world.

So the alchemy he knows is actually very similar to the alchemy that those elves can do.

But whether it was his fate that led to the emergence of alchemy in this world or the other way around, he does not know.

It's a kind of knowledge that owns a system.

This knowledge can be applied in the form of a circle-type of magic.

By drawing magic circles and injecting magic power, he uses his knowledge to transform the form and even nature of matter.

Alchemy is called alchemy because its original purpose was to transform base metals into precious metals, especially gold.

According to this description, in the scientific conception, this magic of turning base metals into gold is already a change at the microscopic particle level, which requires changing the protons and electrons in the nucleus.

In human cognition, only nova explosions or neutron star collisions can produce such changes.

Of course, this is still the ultimate goal of alchemy, and according to legend, this can only be achieved with the Philosopher's Stone.

The alchemy of the vast majority of people can only change the form of matter, but not the nature.

And that's just the tip of the iceberg in this world's magical system.

Although most of the people who use magic live in medieval castles and wear medieval clothes, the things they use are probably more advanced than human technology in the next few hundred years.

But the reason for this strange state is essentially that magic is not created by humans.

To be honest, Char felt that this kind of alchemy was very similar to the alchemy in the steel refining, and he didn't know if it was added by the old man.

Tony nodded, and then he looked at Baigania.

"Take us to the rest of the device."

With such a huge land boundary, it is naturally impossible to rely on such a single cold nuclear fusion to supply energy, and there are at least dozens of such devices evenly distributed in the entire thousands of acres of land.

It's a big project, but fortunately, the main body has already been made by alchemy.

It's also thanks to Char's rich enough treasures, otherwise just these devices would be a price that no individual in the fairy land can afford except Queen Tetania.

But the installation of the energy installation in the last step also took about a week.

After all the installations were completed, Char stood on a high platform built in the middle of the torso of the giant tree called Arvac.

It is a circular platform, and many patterns are painted on the platform.

Of course, the patterns here are only a part, and the entire circle has already covered these thousands of acres of land when it was built.

At this moment, because of the cold core fusion that is running, the entire school exudes a strong magic, even thicker than the land of goblins.

He stood in the center of the circle with the wand he had made not long ago, and at his side stood Vegapunk, Tony, Alicia, and the others.

"Have all the people been evacuated?" Char asked.

Vegapunk bowed, "It's all withdrawn outside the circle." ”

Char looked into the distance, and on the distant hill, a group of dwarves, elves, and goblins were looking at this side, all of whom were the builders of this school.

"If this plan is really feasible." Begania suppressed his excitement and said, "All this will become a legend in the history of architecture." ”

"Then, let this legend become a reality!"

Char lifted his staff and stomped it to the ground.

"Knock~"

With the sound of the first ringing of the morning bell, a huge magical power centered on Char spread out like waves of water on the surface of a calm lake.

Looking down at the entire land from this angle, a huge circle also spreads outward with the giant tree as the center.

"Boom!"

The earth began to shake, and as far as the eye could see, the earth cracked into a large deep furrow, and spread to the sides, gradually enclosing a large area centered on the giant tree.

The area is like an island, gradually becoming independent of the earth.

Then, Tony and the others clearly felt that the ground was rising, and the giant tree was uprooted by this force.

This enclosed thousands of acres of land slowly floated away from the earth, wafting the fragrance of the vast sky!
