Chapter 489: Two-Dimensional Material, Superconductor Graphene!
If one were to discuss the most durable material in the universe, Lynn could not provide an answer, for even the Federation's exploration of the universe in his previous life could only be described as negligible.
However, within his scope of understanding, neutrons are definitely among them!
As the most critical part of forming atomic nuclei, their existence cannot be destroyed even by nuclear explosions, indicative of their incredible hardness!
A mass composed solely of dense neutrons has an unimaginably high density. For instance, neutron stars in the universe have a mass of over 100 million tons per cubic centimeter, making them the densest celestial bodies known, aside from black holes.
Their massive density can warp space-time, meaning they possess a tremendously powerful force field for protection, provided one doesn't get torn apart by their gravitational pull.
Even with the power of a legendary wizard, Lynn could not reach this level and had to seek more reliable alternatives. After pondering for a moment, he quickly came up with an idea.
"071, bring up the information on graphene!" Lynn silently commanded in his mind.
Graphene is an extremely unique single-layer carbon atom material with excellent optical, electrical, and mechanical properties, used in many high-tech instruments and commonly needed in the construction of interstellar warships by the Federation.
Its lightness, hardness, and toughness are remarkable, with a theoretical Young's modulus of 1.0TPa and an inherent tensile strength of 130GPa, surpassing all other metal materials, with hardness more than a hundred times that of steel.
It is also one of the few materials known as two-dimensional, with a thickness of only 0.335 nanometers, one-twentieth of a millionth of a hair strand, equivalent to the thickness of a single atom.However, the term "two-dimensional" does not imply that graphene is of a lower dimensionality.
The Federation's technology has not reached such an advanced level. The so-called two-dimensional material refers to materials in which electrons can freely move in two dimensions on a nanoscale, similar to nanofilms, superlattices, quantum wells, etc.
Describing it as two-dimensional is merely a figurative comparison, while the basic atoms that make it are the very common carbon!
Speaking of graphene inevitably brings up another carbon-based material – diamond, also known as a diamond!
Its hardness benefits from a unique cubic crystal structure within. Each carbon atom in a diamond is tightly bonded to four other carbon atoms, forming a tetrahedron with strong covalent bonds, hence the high hardness. However, due to the structure, it is also very brittle.
Thus, researchers of the Federation had hypothesized as early as the 20th century that the performance of materials could be enhanced by changing and adjusting the atomic arrangement density and the structure of the material.
Graphene perfectly fits this theory. Its carbon atoms are arranged in a closely packed and more perfect hexagonal honeycomb lattice structure, granting it extraordinary hardness and toughness, and it can even stretch like rubber.
According to experimental data within the intelligence, a graphene thickness of only 100 nanometers can easily withstand a weight of over two tons without breaking. What if the thickness is increased to ten centimeters, or one hundred million nanometers?
Lynn did not know, as even the energy-reactive armor of interstellar warships did not need graphene 'that thick'. It's noteworthy that graphene was massively manufactured, produced, and utilized by the end of the 21st century, yet the cost of a single layer of graphene per kilogram was still astronomically high.
Fortunately, they were wizards capable of freely manipulating the elements themselves, significantly reducing the cost of extracting and producing graphene. This convenience is one of the benefits of magic...
After carefully noting all the information, Lynn began experimenting. Under the flow of magic power, a large amount of carbon was produced. With powerful mental control, the atoms were tightly arranged and combined with each other.
Imagining the shape of a honeycomb, crafting a perfect hexagonal lattice structure at the atomic level was not an easy task.
After numerous failures, Lynn barely managed to produce a unit of graphene.
Fortunately, with experience, the subsequent process sped up considerably. By the time midnight approached, Lynn had successfully created a complete circle of graphene shields around him.
Creating this required a significant amount of magic power, nearly depleting one-fifth of his magic power reserves.
The more complex the mimetic material deconstruction, the more intense the consumption, but this seemed a bit too exaggerated...
After all, it was just a creation of carbon atoms.
Lynn found it somewhat strange, but he did not devote too much effort to exploring the increased magic power consumption. Instead, he started researching the new type of protective magic he had developed.
The transparency of graphene is excellent, reaching more than 97%, coupled with its atomic-level thickness, making it difficult to see directly with the naked eye.
However, the arrangement
of countless carbon atoms, neat as a honeycomb and layered thousands of times, with a thickness reaching about 2000 nanometers...
"Truly a perfect creation..." Lynn couldn't help but marvel, also amazed at the delicacy of graphene's structure.
Next, it was time to test its protective capabilities.
Lynn stretched out his hand, and a sword blade several meters long, constantly flowing with magical fluorescence, appeared in his hand.
This was the high-frequency vibrating particle knife used against Saint Cynthia!
"Slash!" Without any mercy, Lynn used all his strength and chopped down.
The particle knife, vibrating hundreds of thousands of times per second, capable of atomic-level cutting, was incredibly powerful. Initially, this strike easily sliced through Cynthia's constructed divine protection and severed her arm!
The powerful particle knife quickly collided with the hexagonal lattice structure of the shield.
2000 nanometers is equivalent to two hundredths of a centimeter, barely visible even under a microscope, yet this paper-thin graphene shield, a thousand times thinner than paper, withstood the powerful slash! On a microscopic level, only about one-fifth of the graphene's thickness was torn apart.
"Very good!" Lynn nodded in satisfaction, knowing he had not held back at all.
Not to mention, this was not even the strongest protective state of the graphene shield.
Because it has another important feature – conductivity! It's one of the best conductors!
For example, one of the Federation's electromagnetic technologies uses graphene's efficient energy storage and conductivity to form a powerful electromagnetic field on the surface of interstellar warships to fend off cosmic rays.
Lynn believed that if he could create a thick enough graphene shield, coupled with an electromagnetic barrier for magnetic field protection, he could reduce the power of a close-range nuclear explosion to a level that a legendary wizard could barely withstand.
However, his previous attempt at the legendary spell "True Realm" had already drained most of his spiritual power and magic power. Considering the need to respond to emergencies, Lynn did not continue to specialize in and practice magic but returned directly to the City of Fire Oil.
With the war approaching, the entire city was engulfed in a tense atmosphere. The rumbling trains never stopped, continuously transporting materials and personnel from all over the kingdom to the City of Fire Oil.
Patrol guards holding fire guns were visible everywhere on the streets. Upon entering the meeting room, even Lynn was checked several times.
This was clearly due to the previous incident of Cynthia's disguised invasion, prompting the council to significantly increase their vigilance.
Lynn did not demand special privileges due to his identity and cooperated fully with the checks, though he was considering the war preparations.
Apart from conquering the Holy City and dealing with the false god, the most important and challenging issue they faced was management.
The empire was simply too vast. Although they had selected many lower-level managers through civil service exams within the kingdom, it was far from enough.
As for the progress of the war, Lynn was quite confident. After more than a year of preparation, the council was no longer as lacking in people and resources as when they first emerged from the land of wizards to conquer the capital.
The newly trained fire gun troops alone had exceeded seventy thousand. Along with a portion of the kingdom's army they had incorporated, they could mobilize over one hundred and fifty thousand personnel.
This was far beyond the kingdom's limit!
The introduction of mechanized large-scale farming and synthetic starch technology had almost resolved the kingdom's basic food scarcity issue. People might not eat well, but at least they could eat enough.
There were countless civilians eager to enlist. If they wished, they could increase the army's numbers to over three hundred thousand at any time.
However, Lynn desired a well-trained, disciplined professional army, not a mob of war cannon fodder and undisciplined robbers.
After entering the meeting room, Lynn immediately summoned Victorio, who was working on magic circle research and modification, to inquire about the reserves of tritium and deuterium fuel and, most crucially, when the next promotion ceremony could begin.
"Probably in three days," Victorio said after pondering.
Promoting a legendary wizard requires a tremendous amount of energy. Last time, they had to evaporate half of Lake Hub to gather enough energy with the help of hundreds of thunder magic-specialized wizards.
Then there was the issue of magic power. The council had used all their magic stone reserves for their two promotions. To quickly gather the necessary magic stones for promotion, Victorio had sent the council's idle archmages to mine in the magic stone mines ten days ago.
For this, he faced quite a bit of criticism, as few archmages were willing to do such menial and tiresome work.
But there were no better options. Magic stones are very hard, having already broken several mining drills. Until mining methods improved, the archmages' cutting magic was more effective.
"By the way, Aurora told me that you didn't add extra fuel for your promotion but managed
