To be honest, after receiving Rebecca's revelation, Gawain really realized for a moment that this little "repulsion trick" was simply the biggest surprise the world gave him: it was simple, low consumption, stable, and the effect was not bad.

Anyone who has contact with a magic power mechanism is familiar with this basic magic: whether it is a magic door that opens automatically or something else, as long as there is a structure in the mechanism that needs to be pushed, there will definitely be a "repulsion trick". Existence, and how much power can it output? As a spell, its power depends entirely on how much magic power you can provide and the performance of the magic material itself, and in Gawain's opinion, its conversion efficiency is extremely high: the gate of the treasure house in the mountains is made of heavy purple steel as a whole. Casting, a single door weighs several tons, and the ancient mechanism that controls the opening and closing of the door can operate easily with almost no mechanical optimization. Of course, this is because the ancient Gondor Empire has black technology, and they purified magic crystals. The performance is a ghost, but the contemporary "inferior products" are not bad, and the magic traps that can push the boulders and run all over the ground are not too rare!

And all of these magical mechanisms, their use of the repulsion magic circle is actually quite primitive and clumsy-that is, the route of the big brick flying, pushing hard with the repulsion magic circle in the spirit of making miracles, and almost never considering the use of levers and gears. sort of thing to optimize...

Therefore, Gawain has high expectations for the magic engine. He believes that even if he uses cheap materials to build the engine, the power that that thing can provide will be incredible.

After the "piston version" of the magic energy engine was discussed, before Rebecca and Hetty completed the transformation and detailed demonstration of the drawings, he thought of further applying the repulsion array to a structure similar to an electric motor. superior.

A motor composed of a stator and a rotor naturally has additional advantages: its structure is relatively simple, and the failure rate is greatly reduced; when it starts, the "repulsion point" on the rotor can directly operate at full load, and the starting torque is large, unlike a piston The starting torque of the type engine is insufficient, and the torque can only reach the maximum after the speed is increased; its volume can be compressed to a small size, and it has a higher volume efficiency ratio when it also uses the magic net for energy; thanks to the magic technology Particularity, the "rotor-type magic energy engine" does not require a brush, nor a "toggle device" used to switch the rune trigger frequently, which reduces the failure rate and improves the overall life of the machine (because Few wear parts), quite a bargain...

But it also has obvious shortcomings - regardless of the advantages and disadvantages of electric motors and internal combustion engines on earth, only starting from the technology of "this world", the rotor-type magic energy engine in Gawain's conception needs a large number of "repulsion points" Distributed on the entire shell to ensure the balance and continuity of the afterburning process, and put together so many independent arrays, it is necessary to ensure that they cannot interfere with each other, the output is accurate and consistent, the distance from the rotor is accurate, and so on. In this way, the technical difficulty of the engine in the mechanical structure is reduced, but the difficulty in drawing the magic circle is increased, and the latter... The technical talents required are more difficult to cultivate. This aspect is a bit more complicated than the mechanical aspect. The trouble is far greater.

But anyway,

This idea is extremely tempting, and it is impossible for Gawain to abandon it.

So he took a blank piece of paper from the side, and under the curious gazes of Amber, Rebecca, and Hetty, he quickly sketched a sketch.

An annular casing, an inner rotor with many inclined vanes (repulsion objects), and many symmetrically distributed repulsion arrays on the casing...

Its structure is so simple.

"This is..." Hetty raised her eyebrows and said curiously and hesitantly.

Gao Wen put down his pen and said with a little excitement, "The second-generation machine."

The three people at the scene other than him were dumbfounded. After a while, Amber looked at Gawain like a monster: "What the hell is your brain?"

"Don't insult my ancestors!" Rebecca became angry when she heard this, picked up the staff and put the head of the staff on Amber's forehead, but she also turned her head and asked, "Master ancestor, what is your brain? How long is it?"

Gao Wen: "..."

It wasn't until two seconds later that Rebecca reacted, and she quickly put away her staff and apologized honestly: "I'm sorry, Lord Ancestor, I can't speak my mind..."

"No, that's not the problem," said the half-elf lady who survived the iron rod headshot crisis without any composure, and continued to exclaim with her eyes wide open, "I haven't even finished discussing your first-generation sketches here, you You actually made a second generation? And it doesn't look like a mother's birth in terms of principle or structure... I'm afraid you have a lot of sketches waiting in your mind?!"

Gao Wen almost choked his saliva into his bronchi: Is this thing considered a mistake?

"It's just an immature idea," he quickly retracted the expression that was about to collapse, and looked at Hetty, who was thinking more carefully, "Its principle is very simple, how do you think it is feasible?"

"It's really much simpler, and the theoretical feasibility is very high...but it's probably not easy to do in practice," Hetty could see the problem at a glance, and the answer was exactly the same as Gawain's conception, "The mass repulsion method The arrays are arranged together, and in this symmetrical and close arrangement, they are almost specially prepared for magic resonance, they will interfere with each other 100%, and whether they can move after activation is a problem."

"What if the diameter is made larger, so that the distance of each 'repulsion point' also becomes larger?"

"...The feasibility is still not high, I can understand what you mean, these repulsion points must be continuously 'relayed' in order to push the rotating part in the middle with maximum efficiency, so their distance is limited no matter how far they are, not so much distance. , it's better to find a way to add a forbidden magic structure between the circles to block interference, but in this way... the cost is probably terrifying."

Gawain immediately twitched the corners of his mouth with a toothache: Even the cheapest materials are the precious metals in the magic materials. If they are really used in mass-produced machines, even if he dies on the spot and then people bury them, Rebecca I can't afford to collect tickets with Heidi and let people from all over the country come to visit... What kind of analogy is this?

"Then let's do a prototype study when we have spare energy, it's also considered a technical accumulation," Gao Wen sighed, "First, get the piston prototype, and most of its parts should be handed over to Hammer and his apprentices. All can be made by hand. The more difficult parts and the repulsion mechanism are handed over to the new rune craftsman. Remember, the first machine does not need to consider the cost. As long as it can run safely and stably, we will succeed - and It's not even a problem to sacrifice some performance on top of that."

Heidi and Rebecca left with a lot of blueprints. Considering the administrative pressure on the former, Gawain gave Rebecca the main task of making the magic engine prototype, while Heidi only provided some technical support. , which makes Rebecca happy again.

After the two of them left the tent, Gawain gathered up the remaining drawings and handed them over to Betty, who was squatting on the ground nearby, earnestly practicing writing with twigs: "Put them away. By the way, I'll ask the carpenter to I made a small desk for you, and it will be delivered to your tent in the evening, and by the way, there is also a set of stationery and some white paper - save it."

Betty took the sheepskin bag with the blueprints and was stunned for a moment, followed by a very happy expression, and bowed hard and almost threw herself forward: "Thank you sir~! You are so kind!"

The little maid almost jumped away.

Gao Wen smiled and looked at the jumping back of the little maid, couldn't help but shook his head with a smile, Amber's eyes became strange: "I'm surprised, you are so busy all day, and you still have time to take care of this. Silly girl... Could it be that this guy's real hobby is this? Hey—you guys are popular with your own maids... ahhhhhhhhhhhhhhhhhhhhhhh!"

Gawain pinched Amber's ear hard, and said, "What kind of hobby is there? I just like that child's diligent, studious and self-motivated spirit, can't you keep your mind clear?"

Amber rubbed his ears while looking at Gawain angrily: "Don't you usually say that my brain is clean?"

Gao Wen: "...I mean your mind is blank and ignorant!!"

"Huh? Don't you praise me for a long time?!"

Gawain glanced at the humiliating half-elf and walked towards the tent door.

Amber Guo couldn't hold back his curiosity and followed up: "What are you doing? Are you going to secretly eat delicious food? Take me one!"

After Gao Wen waited for Amber to follow, he said casually, "Go and talk to that big iron ball. It has been lying in the tent for so long, it should be willing to tell me something."

When Amber heard this, he immediately lost interest: "Oh, then I won't go..."

As soon as Gawain fished it, he put the cargo in his armpit and prepared to take it away.

But this time, he failed: Amber, who had been tossed so much before, had the experience and fled into the shadows the moment he was caught. out.

"Go talk to the ball~" Amber shouted proudly from a distance, "I'm going to find Betty for a meal~~"

Gawain glanced at this "name guard" who did his own way, waved his hand and turned away.

In front of the special tent in the south of the camp, Gawain asked the guard about the metal ball: "What's going on with that guy in the tent?"

"No," the dutiful soldier straightened up and replied, "We've been here all the time, and the ancient magic device just stayed in the tent and didn't mean to go out."

The ancient magic device, this is the explanation that Gawain gave to the soldiers who witnessed the metal ball, and now it seems that this explanation has been accepted by them.

After casually encouraging the soldiers who were standing guard earnestly, Gawain stepped into the tent.

The metal ball floated well in the center of the tent, about half a meter from the ground, looking like a sci-fi suspension device.

But this sci-fi ball snarled: "Mom, I thought you forgot if you threw me here! There are a group of dumb soldiers standing guard around, or it's that annoying little boy. The old man came in, or it was the female human who likes to wear a red dress. It's boring. Let me tell you, if I didn't take commitment seriously in this game, I would have left early this morning..."

Gawain ignored Ball's chatter and went straight to the latter: "I'm here to chat with you today, first to confirm one thing - you, shouldn't be from here... Ball?"
