Spells are basic techniques that are listed in addition to formal spells and can also be performed by apprentice-level mages. Usually, they are extremely difficult to learn, and the spell models that need to be constructed are simple enough that even children of several years old can understand them. level, but correspondingly their effects are extremely limited and their 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 as "preschool education."
Gawain knows a few very interesting "tricks", such as the pre-transformation trick "Dyeing", which can dye the target's hair into random colors, but there is nothing other than dyeing. The lethality can only last for two hours; or the "Mind Training" trick, which is simply used to temper mental power, will summon a phantom within the caster's own field of vision immediately after it is cast, and this phantom will immediately begin to read the spell aloud. The youthful and sad literature written by the spellcaster when he was a child is kept chanting until the spellcaster voluntarily stops the effect of the spell. It has an incredible effect on tempering the mind...
Okay, the youthful sad literature is written by Gao Wen. According to my own understanding, in the local mage's perception, this phantom mainly talks endlessly about all the failures and stupid mistakes in the caster's life. Because the phantom can only be seen by the caster himself, this is probably a psychological suggestion type. It is a technique between magic and technology. It is very effective for tempering the spirit, introspecting, and summarizing experience, but most people are not willing to learn this.
As for formal mages, they are unwilling to call people who only master magic tricks the same as themselves as "spell casters". Those who perform a few tricks on the street to deceive ignorant civilians even rely on Those who fool the country knights with a few tricks are all bad apprentices, and even apprentices will not take mastering a few tricks as something to be proud of - but on the other hand, if you can't even master a few tricks, then it will definitely It's worth being embarrassed...
Rebecca is obviously a powerful member of the mage embarrassment world.
The repulsion trick that almost caused a psychological shadow in her childhood is considered to be a rare and relatively powerful one among all kinds of tricks.
It is one of the prerequisites for force field spells. It is a variant of the "thought movement" that is also a magic trick. It is also a part of later exercises including gravity control, levitation, and plastic hand. A training technique for a series of spells. The function of the repulsion trick is to push away objects directly in front of or around the caster (the specific effect depends on the type of rune text added when constructing the spell model). The weight of the pushed objects depends on Depending on the strength of the caster's magic, it is one of the few cantrips that can have some effect in combat - pushing an enemy away, or staggering them off balance.
Gawain knew about the 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 air flow—even if he occasionally flashed the model of the electric motor, he failed to connect with the most basic "repulsion trick" in the world.
Watching Rebecca describe her thoughts enthusiastically, Gawain reacted with a bit of self-deprecation.Save yourself——
Don’t overestimate the broad ideas and otherworldly experiences of “travelers”. These ideas and experiences may have miraculous effects, but in many cases they will also become the time travellers themselves. The constraints and stumbling blocks, just like this time: Gawain Cecil originally had the repulsion trick in his memory, but why didn't he think of it?
Because Gawain’s mind 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 does Gawain have to add a sealed cylinder to the machine, so her thinking is not limited by this at all - she only needs Gawain to come up with a big idea, and then add her own good brain and the world's With magic knowledge, she can come up with more perfect solutions.
Of course, a very important reason for this is that Rebecca is indeed gifted. With her advanced ideas, in this world, as long as she does not starve to death, it is possible to become a great person, at least. The kind that can be printed in a history book and take up two class hours, but one thing is undeniable: How are the people from other worlds so stupid?
I just didn’t think in that direction!
Hetty was also opened up by Rebecca's idea. She took a piece of paper and casually sketched runes and lines on it: "Yes... the repulsion trick is also very suitable for transformation into simple The spells of the magic circle, and in fact many magic mechanisms, such as automatically opening doors and the most common floor traps, are all driven by repulsion tricks - but no one has ever thought that this power can be transformed into a A standardized machine that can operate continuously... Ancestor, your wisdom and thinking are truly unfathomable."
As she spoke, she handed over the sketch she drew in her hand.
Gawain was so praised by Hetty that he sweated on the back of his head: He was not done with his introspection yet...
He took Hetty's sketch and glanced at it and found this Not only are several of the simplest repulsion arrays outlined, but the cheapest combination of materials that can accomplish the corresponding spell effects is also marked below them.
As expected of someone who is thrifty and thrifty - if there was no Hetty in the camp, I don’t know how much more money would be spent.
The three people put their heads together and began to discuss with great interest the "repulsion trick", which is an extremely basic thing in magic. Rebecca first pointed at Gawain's original drawing. Cylinder: "If you are using a repulsion trick, then the sealed metal tube can be removed directly, or at most, a protective cover can be left to prevent foreign objects from falling in. It does not need to be so tight at all."
"We can Carve the repulsion array on one end of the base and let it push this thing called a 'piston'," Hetty was also interested in research, "But how does the pushed piston come back?"
"Use inertia, the inertia of this iron wheel, it is called a 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 methodDuring the formation, the flywheel rotates and resets the piston. ”
Amber stared at the side for a long time. She didn’t understand it at all at first, but as Gawain and the other two discussed it, she finally got some clues: After all, the basic principle of this machine It's not really complicated. Its main structure is just a bunch of basic wheels and connecting rods. As a thief, Amber often deals with various traps. She is still not unfamiliar with those wheels and connecting rods. Everyone was discussing the reset of the piston, and she said faintly next to her: "What about the process of the piston approaching the repulsion circle again? At this time, the magic circle is still pushing it outward - but at this time, the big wheel has to complete the last half circle before it can continue to exert force, so at this time the machine is competing with itself, right? "
"Yes..." Hetty frowned when he heard this, "When the piston moves away, it naturally needs the repulsion array to push it, but when the piston resets, the repulsion array will offset the useful energy. The power..."
"'Useful power' is called 'work'," Gawain took this opportunity to instill in the other party the terms he was familiar with, and at the same time he had already thought about how to solve the problem of machine "with himself" "Competition" problem - for four-stroke engines or other classic engines on the earth, exhaust is needed to relieve pressure in the cylinder during the piston reset process, but for this machine, he needs to stop the repulsion array at the moment the piston is reset. , "Rune trigger, we can use the rune trigger to control the repulsion array - when the piston moves away from the base of the power mechanism, the rune trigger is turned on, and when the piston returns and approaches the base driven by the flywheel, the rune trigger The trigger was interrupted..."
Various magic symbols popped up in Hetty's mind: "But how to control it? The flywheel spins very fast and the piston moves very fast. For a magic spell that responds so quickly, the position of the rune trigger must be switched in an instant, which requires advanced runes..."
As a result, she still had trouble with her end. Without finishing thinking, Rebecca said casually: "Tie the rune trigger to the piston. When the piston is close to the base, the base will be opened, and then the piston will be pushed away. Push away as soon as it gets close, and push as soon as it gets close. Walking...wow, bouncing. ”
So what picture appeared in this girl’s head that caused the word “jumping” to appear?
Hetty and Gawain stared at Rui. Beka, the former was surprised by the ingenuity of this solution, while the latter marveled that Sha Roe Deer is really a genius in science and engineering - how she managed to seamlessly switch between magic knowledge and mechanical knowledge, and be able to jump out of her current thinking in an instant Doesn't her mind need to be cooled down to achieve results in new ideas? Or is it that the two parts of knowledge are running simultaneously in her mind?
Errui? Beka winced when she was stared at: "Did I say something wrong? "
"No, no, no, this is a very good idea," Hetty waved her hand quickly, "And I also thought of more: Why do we only carve a repulsion circle? The piston has to move back and forth, so we can completelyThe other end is also engraved with a repulsion circle, so that the piston can be recharged twice in one reciprocation..."
Gawain also looked at the sketch on the table seriously, thinking about the runes in his mind Regarding the location of the trigger, I suddenly had some ideas: "In addition, fixing the rune trigger on the piston is not the best way. This means that it will only be turned on for a moment during one operation. We can connect it to the flywheel. On the rotating shaft, the two rune arrays at both ends of the piston are controlled by this trigger, and a 'toggle' device is used to switch the magic circuit where the trigger is located. That is to say, when the flywheel rotates for the first half of the circle, the runes are inside the first circle, and during the other half of the flywheel, the runes connect to the other circle, so that the piston is pushed away. During the entire process of the repulsion array, the first repulsion array is functioning until the piston reaches the farthest point - at this time, the first repulsion array is closed, the second one is opened, and the piston is reversed. What do you think? ? "
Rebecca opened her mouth, looked at Hetty, and then at Gawain, and suddenly she flattened her mouth and became frustrated: "Sure enough, I am still the stupidest..."
"You're not stupid at all! "Gawain was immediately dumbfounded by this girl who had a habit of feeling inferior. "You opened up the idea of the repulsive force array. Your aunt and I were just tinkering with it on this basis. ”
Rebecca continued to purse her lips: “But the idea of this machine was proposed by your ancestor. "
"But without your inspiration, this machine of mine would probably always be just a blueprint," Gawain laughed, "Don't you think you are awesome? "
"Really? "
Gawain and Hetty smiled and nodded together: "Really, really." ”
“Oh! "
"By the way, ancestor, have you given this device a name? Hetty suddenly remembered something at this time, "This 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 his mind, "Then let's call it the magic engine. "
Hetty slowly smiled as she listened to this unfamiliar word combined with strange grammar: "Ancestor, this is indeed a good name. ”
Rebecca also nodded repeatedly: “Yes, yes, although I don’t understand what it means, he seems very handsome!” "
Looking at the two "granddaughters" who were caught in excitement and joy, Gawain looked down at his sketch, and a new idea came to his mind:
This structure, Can we continue to improve?
Or...now that we already have the repulsion circle and the rune trigger, can we simply make a more advanced machine with a completely different structure? Come?
For example, like a motor driven by electromagnetic force, cancel the piston, connecting rod, and crankshaft, and directly carve the repulsion array on the annular shell at a certain angle to push the guide magic inside. Rotor?
