The Whirling Mana Furnace was developed specifically for the Slime Oil, which is the work of the Edible Society, and these druids found that the sample labeled Ninety-Seven had the "Devourer" property when they were searching for the Edible Slime.

This slime from the Weeping Sand Sea was originally called "Demon Sunflower Slime", and it can absorb the magic power of various levels of magic crystals. Normally, it is as dry as the bark of a tree, but as it absorbs more mana, it swells to become moist and smooth. When saturated, it will not explode like Specimen 37, but will become a water-like existence.

Because many adventurers didn't know this strange slime, they scooped up the magic sunflower slime in the sand sea and drank it as water, and there were many casualties.

After the Edible Society discovered this slime, the Demon Working Committee took over and researched how to use it. Sorcerers from the kingdom of Brad and alchemists from West Fein worked together to create this magic oil.

Li Qi didn't have the energy to delve into the specific principle, he only knew that the guys on the mysterious side made the demon sunflower slime in a state of escape from the demon by means of rapid demon extraction, so that the colloid could preserve the demon-absorbing properties. Then remove the slime crystal, remove the epidermis, grind the colloid into powder, absorb it with some kind of neutral oil to maintain the activity of the colloid, and then flow through the magic crystal to absorb the magic power, and get the slime magic oil mixed with the magic slime liquid and neutral oil.

When you use it, you can just put the magic oil in the magic absorption array transformed by the hedron energy supply circle, but this is the problem. Neutral oil is indispensable, and its presence hinders the magic extraction of demonic slime liquid by the magic absorbing array, and can only absorb the magic power of the outer layer of magic oil.

This is not difficult for magic scientists who already know how to use mechanical principles to solve problems, and the design of Mikhail's automatic magic gun inspired them. They made a sleeve that could be rotated, and engraved the magic absorption array on the inner wall of the sleeve. After the magic oil is poured into the inner tube, the magic circle is activated, and the initial magic power obtained pushes the inner tube to rotate at high speed, constantly stirring the magic oil, and improving the magic power supply efficiency of the magic oil, which is the origin of the name "whirling magic furnace".

Considering the need for continuous oil supply, the researchers devised a multi-stage model with more "reactor blocks". While the new oil is continuously fed, the old oil is pushed to the next cylinder. After testing, the optimal balance between the oil supply speed and the number of cylinders was found, and the existing three-stage magic furnace was five-cylinder, and the six-stage magic furnace was nine-cylinder.

After the magic power in the magic oil is absorbed, the impurities left over from the neutral oil and the magic slime will be left, and the impurities will heat up due to the rapid extraction of mana, and the neutral oil will also heat up after high-speed stirring.

The heat of these residues is quite huge, and the method that the researchers came up with is to add an ice circle to cool it with ice, which naturally produces a large amount of steam.

Richie felt innocent, he didn't expect Finn's magic technology to be distorted into a steampunk style.

The Legion was complaining about the new magic chariot equipped with this magic furnace, and the flickering white smoke was a perfect target, but ...... To be honest, it's quite emotional!

Thinking that the magic flying boat was also dragging a long line of white smoke, clearly indicating the flight trajectory, Li Qi also had to give instructions that the magic furnace used in the military must improve the heat dissipation design and solve the problem of steam loss.

Steam isn't the biggest headache for the magic furnace, it's the weight.

Because there is not enough magic steel, the cylinders of the magic furnace are all made of copper and refined gold, and the total weight of the third-level magic furnace is as high as two tons.

Used on the magic chariot, such a weight can still be beared, but the magic flying boat can't bear it. After all, this is not only the power system, but also the propulsion system of the floating system.

After the power system project team of the Mobile Fortress Project took over the magic furnace technology, they tried to make a lightweight transformation with the magic steel in stock, and the results were not bad, it could be reduced to only one ton, which should be able to meet the needs of the magic boat.

It's a pity that at the current price, each magic furnace will cost nearly five or six hundred thousand gold bushels of magic steel, which is completely unimaginable, let alone affordable.

"Since Vicky said that Eve will be able to break through soon, let's not think about the matter of Magic Steel for now. ”

Li Qi can only pin her hopes on Eve, and she is trying to use magic technology to create magic metal. If a breakthrough is made in copper, it will not be far from self-produced magic steel.

Aurora reported that the transport boat would arrive in four or five days, and that it would first send the druid to send some light weapons with a space magician, and of course it would be a bird.

Taking advantage of the past few days, Li Qi is going to come up with a draft first, and when he returns, he can take the Magic Guided Aircraft Research Institute to work. That's right, in order to realize his unfulfilled dreams in the earth world, he abused his position and became the director of the institute himself.

"As the saying goes, as long as the power is enough, the bricks will fly into the sky. Since there are floating crystals to counteract gravity, then the problem is simpler, just solve the propulsion system. ”

Richie clicked on the manual in his companion and consulted the spell descriptions one by one.

The existing aircraft basically use levitation and flying, and some small aircraft only use flying. In short, in terms of the propulsion system of the aircraft, the magic craftsmen of the Finn world have subconsciously chosen the technique of flight.

The flying spell is a third-level spell, and the caster is very light on himself, but the limit speed is only seventy kilometers per hour, and this spell is just used by the mage to jump over the wall and pass over the pit and pretend. The Master made some enhancements and improvements to it, and used it on the floating ship, but it was not much faster.

Seeing that the flying technique also has various states according to the weight of the load, under a very light load, it can be like moving on flat ground, moving forward and backward and hovering anything, Li Qi finally understood why the magic master chose this spell, and he could cast the secret technique of jumping left and right!

The question is, is it meaningful for you, a big guy hundreds of meters long, to jump sideways left and right in the air?

From the perspective of the generalized law of conservation of energy, since the third-level spell of flying can do so many things, it must be much less efficient than a spell that focuses on propulsion.

So what spell should you choose?Tempest?Make a device similar to a magic cannon, summoning the wind to come out and propel the plane...... No, the flying boat forward?

"Wow, you've got a crater all over your head right now. ”

The familiar thought swayed in the bottom of my heart, it was Xiaohong.

She said shamelessly: "I've read the plan and charter you made, so-so, it's okay, I've already arranged it." ”

The tone changed to disdain: "There is nothing wrong with the direction of the magic flying boat, but in the specific design, are you too ignorant of the scientific achievements of the earth world? Even Youzan is using the principles of electricity and mechanics to conduct basic research on extraordinary power, and Aurora is studying success management." You're good, subconsciously ruled out earth science, and all you have left is magic. ”

Li Qi retorted: "Actual analysis of the actual situation, there is extraordinary power, how can the design principles of the aircraft in the earth world be moved to the world of Finn......"

He was shocked again: "Wait, what is that success management? Isn't that chicken soup? How can you get Aurora to drink something?"

"I've already told her", Xiaohong didn't get out of rhythm by him, and chased after him: "The question is where are you seeking truth from facts? There are ready-made things that don't have to turn to the magic route, you are a new form of dogmatism." ”

As a aircraft designer who once had the possibility, Li Qi was extremely disdainful of the provocation of a layman like Xiaohong: "Where am I dogmatic? My idea is to summon air with the Temporal Technique, and then use the Scorching Technique to heat the air, and through turbine compression, the hot air is sprayed out." Yes, I'm talking about turbojets, but this is a jet engine that doesn't require air intakes. ”

Xiaohong was stunned, and said unwillingly: "Alas, didn't you just say that you don't need propellers and jet engines?"

"I'm talking about not using that kind of pneumatic layout", Li Qi dragged and said: "By the way, this term is too professional, you must not understand, I said it simply, that is, no wings." ”

Although Xiaohong was still fighting, her tone was a little empty: "Don't want wings? How to control the direction? I still understand this, don't fool me!"

Li Qi was proud that he had finally crushed Xiaohong in the professional field: "The spaceships that fly out of the atmosphere have no wings, how do they control the direction?"

"You wait——!"

The familiar sound of flipping books sounded, and Li Qi said angrily: "You are hanging up again! This is cheating!"

Xiaohong ignored him, flipped and flipped, and kept making a sudden sound of oh oh.

After a long while, she snorted with a hearty sigh.

"You're right, but you're still making two mistakes. ”

"First, since you are fighting in the main plane, you are flying in the air, and you don't need to summon the air with ready-made air, which is a superfluous waste from the perspective of the generalized law of conservation of energy. With the same amount of energy, you can get more power!"

"Don't tell me anything about wind spell attacks, don't rely on wings to fly and adjust your attitude, if you just take in your breath, it won't be affected too much!"

"Second, the magic jet engine you envisioned, except for not having air intakes and not burning outdoors, doesn't the other parts have to follow earth technology?"

"But even the early jet engines have a lot of attention to the materials, construction, and other aspects, which is completely different from the route of the Finn World Magic Guide Technology, are you sure that you can get these technical details in a very short time? Don't forget that your original intention is to get the magic flying boat as soon as possible, and it is best to do it in a few days like the magic guide gun. ”

No matter how powerful an expert is, he will feel powerless in the face of the goddess who is open, and Li Qi has to admit that what Xiaohong said is very reasonable.

He changed to an attitude of humbly asking for advice: "Then what do you think?"

"That's not easy!"

Xiaohong's thoughts made Li Qi think of her posture, holding her head high, one hand on her waist and the other hand on her front fingers, and the whirlpool on her fingers could be seen clearly.

Xiaohong said three words powerfully: "Electricity, wind, fan!"

Li Qi instinctively refused: "That's not safe at all!"

Fighting the floating ship with a big electric fan, the electric fan was rubbed a little, and the whole plane had to be finished.

"Of course it's not safe to put it in the front, but what if it's in the back?"

Xiaohong brushed out a few pictures in his heart, Li Qi was stunned, and suddenly realized, yes, the electric fan can be placed behind the buttocks!

Those pictures are Eagle Sauce's XP-55, Little Japan's Shock, and a large number of modern drones represented by Eagle Sauce's "Predator".

Xiaohong smiled and said, "How, are you convinced?" I'll send you the information of these electric fans after putting them on the buttocks, mainly the appearance of the fan blades. If you set up a magic wind tunnel in the research institute to do a test, the progress should be very fast. ”

"Little Red ......"

Li Qi called her in an emotional tone, making her hum happily.

"You are a golden finger, you are really powerful, hardworking and willing to work, you can be called a model worker. ”

"Roll ——!"

In the midst of laughter, Li Qi settled on the basic draft.

Compared with jet engines, electric fans are indeed very advantageous, and the wonderful thing is that it is so simple to engage in electric fans in Finn time, using magic to stimulate the magic bearings widely used on puppets, driving the propellers to rotate, in addition to installing the necessary control equipment, there is no need for any other transmission and heat dissipation.

This doesn't mean that the jet engine is abandoned, and the electric fan is still not safe enough even if it is placed behind the butt, but the electric fan can be made quickly, and the jet engine will have to take time to take its time.

With the direction clear, Richie immersed himself in the design and remained busy until the evening, until Karin came over with a stranger.

The person who came was a middle-aged male magician, with a cold face, exquisite appearance, elegant temperament, and a familiar Hadran accent as soon as he opened his mouth, which made Li Qi immediately understand the identity of this person.

The original Hadron royal magician, now the royal magician of the Dawning Empire.

The magician politely saluted Richie: "I have been commissioned by Her Majesty the Empress to contact Her Excellency the Duke......"

Sure enough, Theresia has eyeliner next to Romulus!

Of course, it may not be hidden by Romlëth's side, but it can be seen that Theresia attaches great importance to espionage work, and there is really a shadow of her father in this regard.

"I remember that I have been stripped of the title of duke by His Majesty", Li Qi joked, secretly saying that Theresia must have received the news of Romrose's establishment of the empire, and also knew that she was here, so she came directly to inquire about the progress of the mission.

The magician's smile remained unchanged: "That's a piece of Your Majesty's kindness to fulfill you." ”

This guy's status by Theresia's side is not low, and he knows that he has a tacit understanding with her in politics.

The magician pulled out a crystal ball and placed it on the table, recited a spell, activated the crystal ball, and exited the tent.

"It's not nice to look at her", Karin went out with her arms in her arms.

Theresia is half-dressed, dressed as if she had just finished a meeting.

She looked at him with a somewhat unfamiliar gaze, which made Richie a little apprehensive.

The empress's voice was a little hoarse: "I haven't seen you for a long time, ...... Richie"

It's been less than a month, so why has it been called for a long time?

Of course, a lot has happened in this time, and to be honest, Richie feels that it is a bit long. Looking at Theresia's stunning face, she also felt a little strange, as if her chin was a little rounder, making her more luxurious and elegant than before.

The empress said this and said nothing, so she looked at him quietly, saw that his scalp was numb, and hurriedly said, "About the negotiation with Romrose......

"I'll talk about that later," the empress sighed, "you...... And your goddess, it seems that she is in some trouble. ”

Without waiting for Li Qi to reply, a slight smile bloomed on her face: "Speaking of which, your goddess is really special." ”

Remembering Xiaohong's trip to Heavenly Mountain, which mentioned that Theresia's spirit body manipulated the archangel's clone of Kem, and fought with her against the evil god and killed one of the clones of the god of killing.

When Terecia said this, did she remember the situation in Heavenly Mountain?

"Although your goddess has caused a lot of trouble in Heavenly Mountain, the position of fighting the evil gods is the same as that of Kem, and we have worked together to achieve results. ”

Theresia said: "I don't agree with the revenge of the goddess of commerce now, so in terms of trade, I will help you, and you will know the details later." ”

Great, it's mine...... No, it's the just Theresia as it is!

When Li Qixi overflowed, Theresia's expression also changed slightly, but she quickly became indifferent again: "So, tell me about your progress in Romulus." ”

Richie took a moment to make the situation clear, and made no reservations except for the name of the empire being his own suggestion, and his "friendship and mutual assistance agreement" with Romrose.

Theresia said cheerfully, "No problem, when Sylvie has made decisive progress in Bled, I will personally go to the vicinity of Hiroka to meet with Romulos." Hopefully, until then, he can hold off Belino's army. ”

Li Qi said cautiously: "Then do I still need to report to Your Majesty in person to Valentine?"

"Your Majesty?"

Theresia let out a bitter chuckle: "I have stripped you of your title and domain, you are no longer my vassal, and I am no longer your majesty. ”

Li Qi thought about it for a moment and decided to remain silent.

Theresia's eyes were misty, and she sighed faintly: "So, what is the relationship between us now?"
