Chapter 102 Magic Engine

Welcome, please remember the address of this site: , mobile phone reading, so that you can read the latest chapter of the novel "Sword of Dawn" at any time...

Tricks are basic skills that are listed outside the formal spells and can also be performed by apprentice-level mages. Usually, they are extremely difficult to learn. However, the corresponding effect is also extremely limited, the function is very single, and even many tricks are not practical in combat or work, but can only be used as a supplement to formal spells or "preschool education".

Gawain knew a few very interesting "tricks", such as the pre-trick "Dyeing" of Transfiguration, which can dye the target's hair into a random color, but it does not have any lethality other than dyeing, and it can only It lasts for two hours; or the trick "Mind Exercise" that is simply used to temper mental power. Immediately after performing it, a phantom will be summoned in the caster's own field of vision. Literature, which keeps talking until the caster voluntarily stops the effect of the spell, has an incredible effect on tempering the mind...

Well, the literature of youth and sadness is Gawain’s own understanding. In the cognition of local mages, this phantom will mainly talk about all the failures and stupid mistakes in the caster’s life, because the phantom can only be used by the caster himself. See, so this is probably a kind of psychological suggestion, a skill between magic and technology. It is quite effective for tempering the spirit, introspecting, and summarizing experience, but most people are not willing to learn this.

For official mages, they are reluctant to call those who only master tricks the same "casters" as themselves, those who perform a few tricks on the street to deceive the ignorant commoners, and even fool the country knights with a few tricks All are crappy apprentices, and even apprentices don’t take mastering a few tricks as something to be proud of—but correspondingly, if you can’t even master a few tricks, it’s definitely worth embarrassing...

Rebecca is obviously a hero in the world of mage shame.

And the repulsion trick that almost caused a psychological shadow in her childhood is a rare and more powerful one among all kinds of tricks.

It is one of the prerequisites for force field spells. It belongs to the variant of "ideal shifting", which is also a trick. It is also an exercise technique for a series of spells including gravity manipulation, levitation, and evocative hand in the later stage. The effect of the repulsion trick is to push away the items directly in front of the caster or in the surrounding area (the specific effect depends on the type of rune characters added when constructing the spell model), and the weight of the pushed 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 knocking them off balance.

Gawain knew about this trick, but he didn't expect it at all.

All he had in mind was the expanding gas to do work, or the high-temperature and high-pressure airflow-even if the model of the motor flashed occasionally, he couldn't connect with the most basic "repulsive force trick" in the world.

Watching Rebecca enthusiastically describe her thoughts,

However, Gawain reflected on himself with a self-deprecating mentality——

Don't look too high on the "traverser"'s open ideas and experience in other worlds. These ideas and experiences may have miraculous effects, but in many cases, they will also become the constraints and stumbling blocks for the traveler himself, just like this time: the original Gawain Cecil has a repulsion trick in his memory, but why can'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 doesn't know what an internal combustion engine is. She doesn't even understand why Gawain insists on adding a sealed cylinder to the machine, so her thinking is not restricted by this aspect at all - she only needs Gawain Come up with a big idea, and then add her own good brain and magical knowledge of the world, and she can come up with a more perfect solution.

Of course, a very important reason for this is that Rebecca is indeed gifted. As far as her advanced ideas are concerned, in this world, as long as she does not starve to death, she may be a great person, at least if she can be printed in history books. The kind of two class hours, but it is undeniable: where are the strangers stupid?

People just didn't think in that direction!

Heidi was also enlightened by Rebecca's thoughts. She took a piece of paper and sketched runes and lines on it: "Yes... Repulsion tricks are also very suitable for converting into simple magic circles, in fact Many magical mechanisms, such as self-opening doors and the most common floor traps, are propelled by repulsion tricks - but no one has ever thought of converting this power into a continuous, standardized The machine... Ancestor, your wisdom and thought are truly unfathomable."

As she spoke, she handed over the sketch drawn on her hand.

Gawain was sweating on the back of his head by Hetty's praise: "I haven't finished my self-examination yet..."

He took Hetty's sketch and glanced at it and found that it not only sketched several simplest repulsion circles, but also marked the cheapest combination of materials that can complete the corresponding spell effects.

As expected of the diligent and thrifty householder who came here—if there was no Heidi in the camp, I don’t know how much extra money would be spent.

The heads of the three people gathered together and began to discuss with great interest the "repulsive force trick", which is extremely basic in magic. Rebecca first pointed to the cylinder on Gawain's original drawing: "If it uses repulsion force If you do tricks, then the sealed metal tube can be removed directly, or at the most leave a protective cover to prevent foreign objects from falling in, so you don't need to be so tight at all."

"We can engrave a repulsion circle on one end of this base and let it push this thing called a 'piston'," Hetty was also intrigued, "but how does the pushed piston come back? "

"Using inertia, the inertia of this iron wheel, it's 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 repulsive force, the flywheel rotates and resets the piston. "

Amber stared at the side for a long time. At first, he didn't understand it at all, but after the three of Gao Wen discussed and discussed, she finally got a clue: after all, the basic principle of this machine is really not complicated, and its main structure It's just a bunch of basic wheels and connecting rods, and as a thief, Amber often deals with various traps, and she is not unfamiliar with those wheels and connecting rods. At this time, seeing everyone discussing the reset of the piston, she whispered from the side: "What about the process of the piston getting closer to the repulsion circle? At this time, the circle is still pushing it outward - but this big wheel is going to turn at this time. Only after the last half lap can continue to contribute, so at this time the machine is competing with itself, right?"

"That's right..." Heidi frowned when he heard the words. "When the piston is far away, it naturally needs to be pushed by the repulsion circle, but when the piston is reset, the repulsion circle will cancel out the useful power..."

"'Useful power' is called 'work'," Gawain took this opportunity to instill those terms he was familiar with, and at the same time had already thought of how to solve the problem of the machine "competing with itself" - for four-strokes on earth For an engine or other classic engines, exhaust gas is needed to relieve the pressure of the cylinder during the reset of the piston, and for this machine, he needs to stop the repulsion array at the moment when the piston is reset, "Rune trigger, we can use the rune trigger. To control the repulsion 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: "But how to control it? The flywheel turns very fast, the piston moves fast, and with such a quick response, the position of the rune trigger needs to be switched in an instant, which requires advanced The rune..."

As a result, before she could think about it, Rebecca said casually: "Tie the rune trigger to the piston. When the piston is close to the base, the base will pass, and then the piston will be pushed away, and as soon as it is close, it will be pushed away. , push away as soon as you get close... wow, it's bouncing."

So what kind of picture appeared in this girl's head so that the words "jumping and jumping" appeared?

Hetty and Gawain stared at Rebecca. The former was amazed at the ingeniousness of this solution, while the latter was amazed that Silly Roe Deer was a genius in science and technology—how did she achieve the perfect balance between magical knowledge and mechanical knowledge? Can you jump out of your current thinking in an instant and get results in your new thinking? Doesn't her brain need to be cooled? Or are these two parts of knowledge running simultaneously in her mind? Which one is the solution to use?

And Rebecca was stared at and shrank her neck: "Did I say something wrong?"

"No no no, this is a very good way," Hetty quickly waved his hand, "and I think of more: why do we only engrave a repulsion circle? The piston is going to move back and forth, so we can completely in the power mechanism. The other end is also engraved with a repulsion circle, so that the piston can do two afterburners in one reciprocation..."

Gawain also looked at the sketches on the table carefully, thinking about the position of the rune trigger, and suddenly he had an idea: "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 connected for a moment in one operation, we can connect it to the shaft of the flywheel, and let the two rune circles at both ends of the piston be controlled by this trigger, and use a 'toggle' device to switch the trigger position. That is to say, when the flywheel rotates to the first half circle, the runes are inside the first circle, and when the flywheel rotates to the other half circle, the runes are connected to another circle, so that the piston During the entire process of being pushed away from the repulsion array, the first repulsion array is in play until the piston reaches the farthest point - at this time the first repulsion array is closed, the second is turned on, and the piston is reversed , what do you think?"

Rebecca opened her mouth, looked at Heidi, then at Gawain, and suddenly became depressed: "Sure enough, I'm still the dumbest..."

"You're not stupid at all!" Gawain was suddenly confused by this habitually inferior girl, "You opened up the idea of ​​​​the Repulsion Formation, and my aunt and I are just beating and beating on this basis. ."

Rebecca continued to sigh: "But the idea of ​​​​this machine is still mentioned by you, Mr. Ancestor."

"But without your inspiration, my machine would probably always be a blueprint," Gao Wen laughed, "Don't you think you're very powerful?"

"Really?"

Gawain and Heidi smiled and nodded: "Really."

"Oh!"

"By the way, Ancestor, did you name this device?" Hetty suddenly remembered something, "This brand new thing...you have the right to give it a new name."

"Name..." Gao Wen thought about it, and a name came to his mind, "Then it's called the Magic Engine."

Heidi listened to this unfamiliar and strangely grammatical combination of words, and smiled slowly: "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" who were in a state of excitement, Gao Wen looked down at his sketches, and a new idea popped up in his mind:

Can this structure continue to be improved?

In other words... Since we already have the repulsion magic circle and the rune trigger, can we simply make a more advanced machine with a completely different structure?

For example, like a motor driven by electromagnetic force, cancel the piston, connecting rod, and crankshaft, and directly engrave the repulsive force array on the annular casing at a certain angle to push the magic guide rotor inside?
