"So," Harry, however, deliberately ignored Xinghui Long and turned to the children: "Finally, we have finished visiting the Alchemy Workshop. This is the first stop. You all have a little understanding of the basics of magic.
Are you ready?"
Husky and Hal smiled evilly and nodded.
"Hey, don't ignore me?" Evil Star looked unhappy.
"As you know, alchemy is the basis of magic. Almost any kind of magic requires a little bit of alchemy." Harry completely ignored the evil star and continued: "But, alchemy alone is obviously not enough."
?The wonderful thing about magic is that it can be ever-changing, so other magic must be added to the basis of alchemy. Only with the raw materials and changes can it be considered a complete magic."
He pushed out the back door of the alchemy workshop and led everyone to a long corridor: "So, children, can you answer me? What is the change based on the materials collected in alchemy called?
?"
"Husky knows, Husky knows woof!" The dog-man boy raised his hand impatiently: "It must be the elemental change woof!"
"Elemental changes? What the hell." Night Demon frowned and looked at the dog-man boy rather unhappily: "Aren't you Miss Lianyin's son? Lianyin is also a high-ranking magician.
,Why didn’t she even tell you such basic magic knowledge?”
"Uh!" Husky stuck out his tongue: "Mommy said that Husky is an orc, and he won't be able to use magic in this life anyway, so he didn't teach Husky anything."
"Really?" Night Demon raised his eyebrows: "So you are self-taught? What the hell is elemental change, hahaha."
The dog-man boy pouted: "Isn't it a bark? Huski can obviously see it often when playing video games. There are usually fire magic, water magic, wind magic, thunder magic, etc. in the game.
Earth magic bark."
"What are video games?" Unexpectedly, Harry asked, as if he knew nothing about such a thing.
Husky and Hal looked at each other again, feeling extremely incredible. In this modern day with so much science and technology, there are still people who don't know what video games are?!
"Anyway, the people who tell you this kind of thing are simply a group of laymen who know nothing about magic. They have even got the most basic concepts wrong." Night Demon criticized mercilessly, "In fact, it is necessary to summarize the changes in magic.
, the simplest word is [entropy]."
"What is entropy?" Husky and Hal asked at the same time.
"Entropy is a variable that describes the degree of chaos of a system. The higher the entropy, the closer it is to absolute [chaos], and vice versa." Night Demon continued to explain: "Let me ask you, what is the so-called fire magic?
What exactly is it?"
"Hmm...create flames?"
Harry shook his head.
"Creating heat, meow?" Hal, the leopard boy, replied instead.
"Yes." Night Demon continued to explain, "That is entropy change in the thermodynamic sense. The so-called [heat] is actually just the vibration of countless material molecules in the microscopic world. The more violent the vibration of these molecules, the more chaotic the system within the same material will be.
The higher the degree, the greater its entropy."
"I always feel like I understand..." Husky muttered in a low voice.
"Let's talk about the details after seeing the actual operation." Harry walked to a large room and opened its door: "This is for the training and study of low-level magicians, [Entropy Energy Research Laboratory]."
"
Compared with the previous medium-sized room, what Husky and others saw was a room that was three times larger. There were countless complex instruments that were confusing to understand and guess.
There are countless instrument panels and numerical meters on it, most of which are probably used for measurement purposes.
The dog-man boy focused his attention on a nearby instrument. There, a mage was casting a spell on the iron plate on the instrument, heating the thick iron plate to a red-hot state, and the light emitted was particularly conspicuous. No need to ask.
, this mage is practicing "fire magic".
However, this is not all the training content. Husky walked two steps and looked from another angle. He happened to see another mage on the other side of the iron plate, who was also casting spells on the iron plate and heating the iron plate.
On the contrary, the mage was casting a freezing spell on the iron plate, causing the thick iron plate at his end to be covered with a layer of white frost.
This may be some kind of duel for training purposes. One end is cold and the other is scorching hot, but the center of the thick iron plate remains at normal temperature. It is estimated that it will last until the mage on one side is defeated.
"As you can see, the entropy change of thermodynamics actually has two sides. The positive entropy of thermodynamics is burning heat, and the negative entropy is cold. Whether it is cold or hot, it can be easily realized by consuming photons."
Harry glanced at Star Glory Dragon Evil Star: "The fireball technique you see most often also requires the use of entropy magic. Simply put, it uses alchemy to extract enough fuel from the air - usually oxygen and hydrogen.
——Then use entropy change to ignite these hydrogen and oxygen mixed gases, creating a blazing fireball."
"What about ice arrows?" Hal suddenly remembered the magic that the little fishman prince often used, and asked.
"The principles are almost the same. First use alchemy to extract the water vapor or nitrogen in the air, and then apply negative entropy to freeze the water or nitrogen, turning it into a low-temperature ice arrow." Night Demon blinked: "Of course.
, in order to make the ice arrow sharper, there is also a problem of shaping. This involves the entropy change of dynamics, which is what you have been talking about [wind spell]."
Harry stretched out his hand and pointed in the distance: "Look over there."
The dog-man boy and the leopard-man boy turned their heads at the same time and looked in the direction pointed by the Night Demon's finger.
There is another experiment, another training instrument. There, a low-level mage is casting a spell on an instrument similar to a windmill to make the windmill rotate.
"Can someone analyze what he is doing?" Night Demon asked like a teacher.
"Are you using magic on the air to make it move?" Husky tried to answer.
"Yes, that's correct." Harry nodded with satisfaction: "That's the entropy change of dynamics, or kinetic energy magic.
Simply put, it is to exert a force in a fixed direction on the molecules of an object to make the object move. Since there is already a difference in direction, there is no need to consider whether it is positive entropy or negative entropy. Generally speaking, kinetic energy magic is
Calculated using vectors."
"It looks very simple." Husky shook his tail. If he just used magic to make the air flow in the same direction, he could do it...if he could use magic.
"That's wrong. Kinetic energy magic can be very simple when it is simple, but it can also be extremely complicated when it is complicated." Night Demon shrugged, "I think you should have guessed that the alchemy you have seen before is also a kind of kinetic energy in the end."
Magic. Separating one substance from another substance is usually accomplished by relying on kinetic energy magic. For example, the purification of hydrogen. The air is mixed with hydrogen, oxygen, nitrogen, carbon dioxide and hundreds of other trace gases. Think about it.
Precisely extracting only hydrogen from these gases is a process of sifting and separating the hydrogen molecules in the air one by one. Do you know how difficult it is actually to do this?"
Husky stuck out his tongue and remained silent.
"By the way, the flame dragon's breath, which dragons are most proud of, is actually extremely crude. They rarely separate flammable gases from the air so accurately. Instead, they do the opposite and remove the incombustible inert gas in the air.
The gas is removed, for example, the nitrogen is removed. In this way, the remaining combustible gas with many impurities becomes the fuel of the dragon's breath. The casting process can be said to be very labor-saving and ugly."
The evil star rolled his eyes at Harry, and a blue vein appeared on his forehead.
"Ah ha ha ha ha..." Seeing that Uncle Evil Star was about to quarrel with Harry again, Hal immediately changed the subject and said: "Hal knows what wind spells are, meow. But there really are no earth spells, meow."
?"
"So what is earth magic? Who did you listen to to come up with such a mess? Use magic to move the soil and rocks on the ground? Isn't that also a type of kinetic magic?"
Hal tilted his head and thought for a while, and it seemed to be the same thing. All magic that relies on moving objects to attack is actually the application of kinetic energy magic. Even the ice arrow technique of Little Prince Calvin also uses kinetic energy magic.
The part where the ice arrow is launched.
"As a result, kinetic energy magic should have the widest range of applications and the highest frequency of use among all magic."
"Apart from these?" Husky asked, "Are there other types of magic?"
"Of course." Night Demon took a few steps forward and continued: "In addition to thermodynamic entropy and kinetic entropy, magic also has a very important division, which is electromagnetic mechanical entropy. Simply put, it consumes photons to change
Positive or negative charges use potential differences to produce discharge phenomena."
"Oh yeah, it's a lightning magic dog." Husky said with a smile.
"Barely so." Harry said, "Electric energy can actually be converted into thermal energy or kinetic energy, so the magic about electromagnetic mechanics can be ever-changing, which is a very complicated division. Moreover, living organisms can inherently generate electricity, and electricity generation is the main medium for nerve conduction.
.Precisely because most living organisms can generate electricity by themselves and are interfered by their own abilities, they have poor control over magic related to electromagnetic mechanics."
"Well, then isn't thunder magic weaker than other magic?"
"Not entirely. Lightning has a very interesting characteristic, which is [anything that can be a legal target is guaranteed to be hit]. Because the propagation of lightning in the air is close to the speed of light, and it does not need to propagate in a straight line.
If you target an opponent and release a thunderbolt, the opponent cannot avoid it and will definitely be hit."
"Isn't that the thunder and lightning magic that makes you invincible?"
"No. There are no invincible moves in the world. The same is true for spells. Where there are advantages, there are bound to be disadvantages.
First of all, creating a high voltage that can directly kill the opponent is also a very dangerous thing for the caster. Maybe the lightning does not hit the target, but instead kills the mage who cast the spell;
Secondly, although the attack of thunder and lightning is extremely fast and almost impossible to dodge, it can be easily blocked by a force field such as a protective shield. If the opponent consciously releases the shield to protect himself during the battle, the attack of thunder and lightning will be blocked.
The enemy is at his wits end;
The third and most important point... In fact, if you want thunder and lightning to hit the target accurately, you need to meet certain conditions------electric potential difference. For example, if the thunder and lightning emitted by the caster is a
Positive charge, then the target should have a large amount of negative charge to ensure a hit. Otherwise, most objects in the world carry varying degrees of unpredictable amounts of charge, and the emitted lightning can hit any object.
It's totally out of control."
"Well, isn't this kind of magic useless at all?"
"Not necessarily. As long as you know how to control it, lightning magic can easily hit the target." Night Demon continued, and at the same time he led everyone to another corner of the research room purposefully: "Compared to my explanation, you still can't.
It's easier to understand if you see it with your own eyes. Look, this is the correct way to use thunder and lightning magic."
Husky turned a corner and looked in the direction pointed by Daredevil Harry, but saw a training facility similar to a shooting range.
