Tricks are basic techniques that are listed outside of official spells and can be performed by apprentice-level mages. Usually, their learning difficulty is extremely low, and the spell models that need to be constructed are so simple that children of even a few years old can understand them. But correspondingly, its effects are extremely limited, and its functions are very single. Even many tricks are not practical in combat or work, and can only be used as a supplement to formal spells or "pre-school education".
Gao Wen knew several very interesting "tricks", such as the pre-trick "Dyeing" of Transfiguration, which can dye the target's hair into a random color, but it has no lethal effect other than dyeing, and it can only It lasts for two hours; or the trick "mind training" purely for tempering mental strength, immediately after casting, a phantom will be summoned in the caster's own field of vision, and this phantom will immediately begin to read aloud the youthful sadness written by the caster when he was a child Literature, which has been chanted until the caster actively stops the effect of the spell, has an incredible effect on tempering the mind...
Well, this is Gawain's own understanding of youthful sadness literature. In the cognition of the local mages, this phantom will mainly talk about all the failures and stupid mistakes in the life of the caster, because the phantom can only be read by the caster himself. See, so this is probably a kind of psychological suggestion, a technique between spells and technology. It is quite effective for tempering the spirit, introspecting, and summing up experience, but most people are not willing to learn this.
For official mages, they are unwilling to call people who only master tricks the same as themselves "spellcasters". Those who perform a few tricks on the street to deceive ignorant civilians, and even rely on a few tricks to fool country knights Most of them are lame apprentices, and even apprentices don't take it as something to be proud of mastering a few tricks—but correspondingly, if they can't even master a few tricks, it must be shameful...
Rebecca is obviously a titan in the world of mages.
And the repulsive trick that almost caused her a psychological shadow in her childhood is a rare and powerful one among all kinds of tricks.
It is one of the precursors of force field spells, and it is a variant of the "mind shifting" which is also a trick. It is also a training technique for later practice of a series of spells including gravity manipulation, levitation, and evocation of hands. The function of the repulsion trick is to push away the items in front of or around the caster (the specific effect depends on the type of rune bytes added when building the spell model), and the weight of the pushed away items depends on the magic power of the caster. It's one of the few tricks that can make a difference in combat—pushing enemies away, or throwing them off balance.
Gawain knew about this trick, but he didn't expect it at all.
All he could think about was the work done by the expanding gas, or the high-temperature and high-pressure airflow—even if he occasionally flashed the model of the electric motor, he couldn't get in touch with the most basic "repulsion trick" in the world.
Seeing Rebecca happily describing her thoughts, Gao Wen reflected on himself with a self-deprecating attitude—
Don't overestimate the open mind and experience of the "traveler". These ideas and experience may have miraculous effects, but in many cases it will also become the shackles and stumbling blocks of the traverser himself, just like him this time: Originally Gawain Cecil had the repulsion trick in his memory, but why couldn't he think of it
Because Gawain's brain is full of classic engine models on Earth...
Rebecca has never seen a steam engine, and she doesn't know what an internal combustion engine is. She doesn't even understand why Gawain insisted on adding a sealed cylinder to the machine, so her thinking is not limited by this aspect at all—she only needs Gawain to propose A big idea, and then coupled with her own good brain and the knowledge of magic in this world, she can come up with a more perfect solution.
Of course, one of the most important reasons for this is that Rebecca is really talented. As far as her advanced ideas are concerned, in this world, as long as she does not starve to death, it is possible to become a great person, at least it can be printed in the history books. The kind of two class hours, but there is no denying one thing: how stupid are people from other worlds
People just didn't think in that direction!
Hetty was also enlightened by Rebecca's idea. She took a piece of paper and sketched runes and lines on it: "That's right... the repulsion trick is also very suitable for converting into a simple magic circle. In fact, many Magical mechanisms, such as self-opening doors and the most common floor traps, are powered by repulsion tricks—it's just that no one has ever thought of translating this power into a continuously operating, standardized machine ... Ancestor, your wisdom and thinking are really unfathomable."
As she spoke, she handed over the sketch drawn in her hand.
The back of Gao Wen's head was sweating profusely from being praised by Heti: I haven't finished my self-examination yet...
He took Heidi's sketches, glanced at them, and found that not only the simplest repulsive magic circles were sketched on it, but also the cheapest combination of materials that could complete the corresponding magic effects was marked under them.
It's really worthy of being a diligent and thrifty family - if Hetty is missing in the camp, I don't know how much money will be wasted.
The heads of the three of them got together and began to discuss with great interest the "repulsion trick", which is an extremely basic thing in magic. Rebecca first pointed to the cylinder on Gawain's original drawing: "If you use the repulsion trick, If it’s a trick, then the sealed metal tube can be removed directly, or at most a protective cover to prevent foreign objects from falling in can be left, so it doesn’t need to be so tight at all.”
"We can engrave the repulsive magic circle on one end of this base, let it push this thing called 'piston'," Heidi was also interested in research, "but how can the pushed away piston come back? "
"Use inertia, the inertia of this iron wheel, it is called flywheel," Gawain pointed to the flywheel connected to the piston, "it is connected to the piston through the crankshaft, when the piston moves away from the repulsion circle, the flywheel rotates and resets the piston. "
Amber stared at the side for a long time. At first, she didn't understand at all, but after the three of Gao Wen discussed and discussed, she finally saw some clues: after all, the basic principle of this machine is not complicated, and its main structure It was just a bunch of basic wheels and connecting rods, and as a thief, Amber often dealt with various traps, so she was not too unfamiliar with those wheels and connecting rods. At this time, seeing everyone discussing the issue of piston reset, she quietly said: "What about the process of the piston approaching the repulsive magic circle again? At this time, the magic circle is still pushing it out—but at this time, the big wheel is about to finish turning." Only the last half lap can continue to exert force, so at this time the machine is competing with itself, right?"
"That's right..." Hetty frowned upon hearing this, "Naturally, the repulsive magic circle is needed to push the piston away, but when the piston resets, the repulsive magic circle will cancel out those useful powers..."
"'Useful power' is called 'work'," Gawain took this opportunity to instill the terms he was familiar with, and at the same time, he had already thought of how to solve the problem of machines "competing with themselves"—for the four-stroke engines on the earth Or other classic engines, exhaust is needed to depressurize the cylinder during the piston reset process, and for this machine, he needs to stop the repulsion circle at the moment the piston resets, "Rune trigger, we can use rune trigger to Control the repulsive force circle - when the piston moves away from the base of the power mechanism, the rune trigger is turned on, and when the piston is driven by the flywheel and returns to the base, the rune trigger is interrupted... "
Various magic symbols popped up in Hetty's mind again: "But how to control it? The flywheel rotates very fast, and the piston moves fast. With such a quick-response magic formula, the position of the rune trigger needs to be switched in an instant. This requires advanced The runes of…”
As a result, before she finished thinking on this side, Rebecca said casually: "Tie the rune trigger to the piston. When the piston is close to the base, the base will be connected, and then the piston will be pushed away. Push it away as soon as it gets close." , Push away as soon as you get close... Wow, bouncing around."
So what kind of picture has emerged in this girl's head so that the words "bouncing jumping" come out
Hetty and Gawain stared at Rebecca together. The former was amazed at the ingenuity of this solution, while the latter marveled that the silly roe deer is such a genius in science and engineering—how did she manage to seamlessly integrate magic knowledge and mechanical knowledge? Switching, can you jump out of your current thinking in an instant and get results in the new thinking? Doesn't her mind need to be cooled? Or are these two parts of knowledge running simultaneously in her mind? Which one is used when there is a solution
And Rebecca shrank her neck from being stared at: "Did I say something wrong?"
"No, no, this is a very good way," Hetty quickly waved his hand, "and I have more thoughts: Why do we only engrave a repulsive force circle? The piston needs to move back and forth, so we can completely The other end is also engraved with a repulsive circle, so that the piston can do two boosts in one reciprocation... ”
Gao Wen also carefully looked at the sketch on the table, thinking about the position of the rune trigger in his mind, and suddenly had some ideas: "In addition, it is not the best way to fix the rune trigger on the piston, which means that it is It will only be turned on for a moment in one operation, we can connect it to the shaft of the flywheel, and let the two runic circles at both ends of the piston be controlled by this trigger, and use a 'toggle' device to switch the position of the trigger That is to say, when the flywheel turns to the whole process of the first half circle, the runes are inside the first magic circle, and when the flywheel turns to the other half circle, the runes connect to another magic circle, so that the piston The first repulsion circle is active the entire time it is being pushed away from the repulsion circle, until the piston reaches the farthest point - at which point the first repulsion circle closes, the second opens, the piston reverses, What do you think?"
Rebecca opened her mouth, looked at Hetty, then at Gawain, and suddenly became depressed with her mouth flattened: "Sure enough, I'm still the stupidest..."
"You're not stupid at all!" Gao Wen was dumbfounded by this girl who was habitually inferior, "You were the one who opened up the idea of the repulsion circle, and your aunt and I were just hammering on this foundation. .”
Rebecca continued to keep her mouth flat: "But the idea of this machine was brought up by your ancestors."
"But if it weren't for your inspiration, my machine would probably be just a blueprint forever." Gao Wen laughed, "Don't you think you are very powerful?"
"Really?"
Gawain and Heidi nodded with a smile: "Really."
"oh!"
"By the way, ancestor, have you given this device a name?" Hetty suddenly remembered something at this moment, "This kind of brand new thing...you have the right to give it a new name."
"What's the name..." Gawain thought about it, and a name came to mind, "Then it's called the Magic Engine."
Hearing this unfamiliar word combined with strange grammar, Hetty slowly smiled: "Ancestor, this is indeed a good name."
Rebecca also nodded again and again: "Yes, yes, although I don't understand what it means, it seems very handsome!"
Looking at the two "granddaughters" in excitement, Gao Wen looked down at his sketch, and a new idea popped up in his mind:
Can this structure continue to be improved
Or to put it another way... Now that we have the repulsive circle and the rune trigger as a foundation, can we simply make a more advanced machine with a completely different structure
For example, like an electric motor driven by electromagnetic force, cancel the piston, connecting rod, and crankshaft, and directly engrave the repulsive force circle on the ring shell at a certain angle to push the inner magic rotor
