Juggling is a basic technique that can be displayed by apprentice-level wizards who are listed outside of formal spells. Usually, their learning is extremely difficult, and the spell model that needs to be constructed is as simple as a child can understand. However, the corresponding effects are extremely limited, the function is very simple, 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."

Gao Wen knows a few very interesting "tricks", such as the pre-dancing "staining" of the metamorphosis, which can dye the target's hair into a random color, but there is no lethality other than dyeing, and only Maintain two hours; or simply use it to temper the spirit of the trick "Heart Exercise", immediately after the exhibition will summon a phantom in the operator's own vision, this phantom will immediately begin to read the youthful sadness written by the child when he was a child Literature, has been chanting until the operator actively stops the effect of the spell, has an incredible effect on the tempering mind...

Well, the youthful sad literature is Gao Wen’s own understanding. In the local mage’s cognition, this phantom is mainly about telling all the failures and stupid mistakes in the life of the surgeon, because the phantom can only be used by the surgeon himself. See, so this is probably a psychologically suggestive technique between the spell and the technique. It is quite effective to temper the spirit, introspect and sum up the experience, but most people are not willing to learn this.

For formal mages, they are not willing to call those who only master the tricks the same as the "caster" of their own. Those who perform several tricks on the street to deceive ignorant civilians, even rely on a few tricks to flick the country knight They are all lame apprentices, and even if they are apprentices, they will not take a few tricks as something to be proud of - but correspondingly, if even a few tricks can't be mastered, it is definitely worthy of shame...

Rebecca is clearly a member of the Master's shameful world.

The repulsive trick that made her childhood almost a psychological shadow is a rare and powerful one in various tricks.

It is one of the predecessors of the force field spells. It belongs to the variant of the "Ideas to Move Objects" which is also a trick, and is also a series of spell exercise techniques including gravity manipulation, floating surgery, and plastic energy. The role of the reptile trick is to push the item in front of or around the operator (which depends on the type of rune byte added when constructing the spell model), and the weight of the item is determined by the magic power of the caster. It is one of the few tricks that can make a difference in combat - pushing the enemy away or making the enemy unbalanced.

Gao Wen knows this trick, but he didn't think about it at all.

He was full of inflated gas for work, or high-temperature, high-pressure airflow—even if he occasionally flashed the model of the electric motor, he couldn't relate to the world's most basic “repulsive trick”.

Looking at Rebecca's eagerly portraying her thoughts, Gao Wen reflected himself with a self-deprecating mentality -

Don't look too high at the open-minded and alien experience of the "traveler". These ideas and experiences may have miraculous effects, but in many cases it will become the shackles and stumbling blocks of the passers-by, just like this time: originally There is a repulsive trick in the memory of Govin Cecil, but why can't you think of it?

Because Gao Wen’s mind is all about the classic engine model on earth...

Rebecca has never seen a steam engine, and she doesn't know what the internal combustion engine is. She doesn't even understand why Gao Wenfei wants to add a sealed cylinder to the machine, so her thinking is not restricted in this way - she only needs Gao Wen Putting forward a big idea, and then adding her own good brain, as well as the magic knowledge of the world, she can come up with a more perfect solution.

Of course, one of the most important reasons is that Rebecca is indeed gifted. In terms of her advanced ideas, she is in this world. If she does not starve, she may become a great man, at least in history books. The kind of two class hours, but there is no denying a point: Where is the aliens stupid?

People just didn't think in that direction!

Herti was also opened up by Rebecca's idea. She took a piece of paper and sketched the runes and lines on it: "Yes... Repulsive tricks are also very suitable for transforming into simple magical spells, in fact Many magical institutions, such as the automatically opened gates and the most common floor traps, are driven by repulsion tricks - but no one has ever thought of converting this power into a sustainable operation, standardization. The machine... the ancestor, your wisdom and thoughts are unfathomable."

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

Gao Wen was beaten by Herti Kwa's head: the introspection of his own is not finished yet...

He took over Hert's sketches and saw that it not only outlined the simplest repulsion arrays, but also labeled the cheapest combination of materials that would match the spell's effects.

It’s really hard to be home-worked – if there’s less Herti in the camp, I don’t know how much it costs.

The heads of the monks got together and began to talk about the "repulsive trick", the extreme foundation of the spell. Rebecca first pointed to the cylinder on the original drawing of Gao Wen: "If it is a repulsive force If you play tricks, the sealed metal tube can be removed directly, or at most, a protective cover that prevents foreign objects from falling in. It is not so strict."

"We can engrave the repulsion rifle at one end of the pedestal and let it push this thing called the 'piston'." Herti was also stimulated by research interest. "But how did the Pistons who were pushed far back? ”

"Inertia, the inertia of this iron wheel, it is called a flywheel," Gao Wen pointed to the flywheel connected to the piston. "It is connected by the crankshaft and the piston. When the piston is away from the repulsive force array, the flywheel turns and resets the piston. ”

Amber looked at her side for a long time, and at first she didn't understand it at all, but Gao Wensan discussed and discussed that she finally saw the point: the basic principle of this machine is not complicated, its main structure It's just a bunch of basic wheels and connecting rods. As a thief, Amber often deals with various organ traps. She is not too strange to those wheels and connecting rods. At this time, I saw everyone discussing the problem of piston reset. She came to the side and said: "Is the piston re-approaching the process of repulsive force? At this time, the Faction is still pushing it out - but this time the big wheel will turn. After the last half of the lap, you can continue to work, so this time the machine is competing with yourself."

"Right..." Herti screamed. "There is a natural need for a retracement push when the piston is far away, but the repulsive array will offset the useful power when the piston is reset..."

“The 'useful power' is called 'doing work',” Gao Wen took the opportunity to instill the other nouns he was familiar with, and at the same time thought of solving the problem of the machine “competing with himself” – for the four strokes on the earth. For engines or other classic engines, the piston needs to be vented to relieve the cylinder during the reset process. For this machine, he needs to stop the repulsion array at the moment of piston reset. "Rune trigger, we can use the rune trigger To control the repulsion array - when the piston is moved away from the base of the power station, the rune trigger is turned on. When the piston returns to the base with the flywheel, the rune trigger is interrupted..."

There are various magic symbols in Herti's mind: "How do you control it? The flywheel turns very fast, the piston moves fast, and reacts to such a quick magical technique. It is necessary to switch the position of the rune trigger in an instant. This requires advanced Runes..."

As a result, she hadn't thought about it yet. Rebecca said casually: "Take the rune trigger on the piston. When the piston is close to the base, the base will pass. Then the piston will be pushed away. When you get close, you push away... Wow, you jump."

So what is the picture that appears in the head of the bag so that there is a word "bounce"?

Heti and Gao Wen stared at Rebecca. The former was surprised by the subtlety of this solution. The latter was amazed that the silly scorpion was a science and engineering genius - how she did it between magical knowledge and mechanical knowledge. When you switch, you can jump out of your current thinking and get results in a new way. Does her brain need to cool? Or do these two parts of knowledge actually run synchronously in her mind? Which one is used for the solution?

And Rebecca was stared at the neck: "Is it wrong?"

"No, no, this is a very good way," Herti hurriedly waved. "And I still think more: Why do we only engrave a repulsive force? The piston is going to move back and forth, so we can all be in the power The other end is also engraved with a repulsive array, so that the piston can do two times in one reciprocation..."

Gao Wen also looked at the sketches on the table seriously. Thinking about the position of the rune trigger in his mind, he suddenly had a little thought: "In addition, the rune trigger is not the best way to fix it on the piston, which means it is In one operation, it will only be connected for a moment. We can connect it to the revolving shaft of the flywheel, and let the two rune arrays at both ends of the piston be controlled by this trigger. Use a 'toggle' device to switch the trigger. The magic circuit. That is to say, when the flywheel turns to the first half of the circle, the runes are inside the first array, and the flywheel is transferred to the other half, the runes are connected to another array, so that the piston During the entire process of being pushed away from the repulsion arbitrage, the first repulsion arsenal is in effect until the piston reaches the farthest point - this time the first repulsion circle is closed, the second is turned on, and the piston is reversed. What do you think?"

Rebecca opened his mouth, looked at Herti, and looked at Gao Wen. Suddenly, he was depressed with a flat mouth: "Sure enough, I am still the most stupid..."

"You are not stupid at all!" Gao Wen was suddenly laughed at by the habit of inferiority. "The idea of ​​repulsive tactics is all open to you. My aunt and my aunt are just knocking on this basis." ""

Rebecca continued to squash: "But the idea of ​​this machine is what you raised by the ancestors."

"But without your inspiration, my machine is estimated to be a drawing forever," Gao Wen laughed. "Do you not feel that you are very powerful?"

"Really?"

Gao Wen and Herti smiled and nodded: "Really true."

"Oh!"

"Right, ancestor, have you given the device a name?" Herti suddenly remembered something. "This new thing... you have the right to give it a new name."

"Name?" Gao Wen thought about it, and a name came to mind. "That is called the magic engine."

Hetty listened to this strange, vocabulary combined with strange grammar, and slowly smiled: "The ancestor, this is really a good name."

Rebecca nodded again and again: "Yeah yeah, although I don't understand what it means, it seems to be very handsome!"

Looking at the two "grandchildren" who were in the joy of excitement, Gao Wen looked down at his sketches and came up with new ideas in his mind:

Can this structure continue to improve?

Or... Since there is already a repulsion arsenal and a rune trigger, can you simply make a more advanced machine with a completely different architecture?

For example, like the motor driven by electromagnetic force, the piston and the connecting rod and the crankshaft are eliminated, and the repulsion array is directly engraved on the annular casing at an angle to push the inner magic rotor.
