The imperial capital is about 3,200 meters away from the Crescent Collar, and the Golden Lake University Conference will be held for a full month.

This is a very long time and influential wisdom conference that can greatly affect the future fate of the Golden Land.

Since he plans to promote his Great Floating City at the Academy, it is natural that he must be fully prepared.

In addition, when he is away, the affairs of the territory should be well arranged.

Therefore, Lawson experienced the joy of the next high-level twelve-star achievement a little, and turned to plunge into the busy preparations.

About three days later, an elemental apprentice brought him good news.

"Lord, the Mentor says he wants to show you a new foundational element, a wonderful, fascinating, and unpredictable fantasy elf."

So what else is there to say?

Lawson immediately put down all the work in his hand and hurried to the elemental laboratory.

When he arrives at the lab, he finds that Fibbit is already waiting for him.

There was a hint of drunken excitement on his face, and when he saw Rosen, he gently patted the large wooden box on the table behind him.

"Baron, I bet you'll be even more excited than I am when you get to know this amazing little fellow!"

Lawson was looking forward to it, too, but only a smile on his face: "Show it to me."

Fibit opened the wooden box and took out a goose-yellow strange metal with a diameter of three centimeters and a length of 20 centimeters.

"I call it 'Titan Divine Iron' because the pure essence of this basic element is an unusually strong metal."

"At the same time, it is so rare that it should not be found in nature. I consumed 2,000 dira of iron slag to get such a small root."

"It's several times stronger than pig iron, and it can even leave marks on glass."

As he spoke, he took out a piece of ordinary glass, took a stick and scratched it hard, and a layer of white glass powder was scraped off.

Rosen praised from the bottom of his heart: "Very hard indeed."

Generally, iron tools scratch on the glass, and there is not the slightest trace.

Fibbit continued, "But what really fascinates people is its mana properties, a wonderful ability that only the transcendent can possess."

Rosen immediately guessed a possibility, and his heart raced a little.

I saw Phoebit carefully pick up the goose-yellow metal rod and put his left and right index fingers against both ends.

"Look, Baron, my mana will flow from my left finger and flow in from my right finger, forming a mana cycle."

With that, Phoebit began to release his mana.

As the mana flowed, Rosen found that the surface of the metal rod was rapidly climbing up with hoarfrost, which became thicker and thicker, so that the temperature of the surrounding air dropped a little.

"During this time, I poured ten parts of the mana into the stick, and in the end, the mana that flowed back was only reduced by less than one thousandth."

In the Elemental Lab, one mana is equal to one hundredth of the mana cost of a standard missile technique.

Rosen calculated slightly: "Even the best guidedness of the starfall stellar gold is far from reaching this level, and it is even an order of magnitude worse."

"That's right, but the nature of this transcendent conductivity is completely different from other metals."

Phoebe lit up an alcohol lamp and placed a metal rod next to the firework to heat it.

When the surface hoarfrost had melted, he continued, "I will perform the mana flow again."

Rosen looked closely.

The moment the mana began to flow, the alcohol flame became much darker, and the brightness and heat were greatly reduced, and it seemed that it was about to be extinguished in the next moment.

Rosen immediately said, "The power of the flame has been absorbed?"

"That's right. As a result, when I shed one mana, nearly six small parts flowed back into my body."

Lawson's heart was shocked: "Flame mana!"

The essence of the ability to release flames is electromagnetic waves, so the essence of this thing is actinic mana!

He's so lucky, isn't he?

Just thinking about looking for it

The secret method of actinizing mana was directly solved by a basic element.

It feels very unreal, like dreaming. br>

But after thinking about it, I felt reasonable.

Because in his view, the foundation of the world is matter, and the subject of matter is the basic element.

The basic elements make up all life, including transcendent life.

Then, the essence of the power of transcendent life is derived from some kind of substance.

His good fortune was that he found the substance in one fell swoop.

And this situation usually only occurs in the early stages of the great explosion of knowledge.

Because at this time, everyone is ignorant about the method of acquiring new knowledge.

The fruit of the orchard of knowledge has basically not been picked yet.

Everywhere there are low-hanging sweet fruits, as long as the eyes are bright enough, the hand is raised.

And now, Phoebit may have picked the power fruit of the elemental tree!

But it doesn't seem that simple.

A wry smile appeared on Fibbit's face, "Don't be in a hurry to rejoice, Baron, soon you will be in the same distress as me."

He said, "Baron, you release a Breath of Fire wrapped around a metal rod."

Rosen complied.

As the lilac flames swirled around the metal rod, Fibit began to flow mana again.

Rosen immediately realized that his mana had been attracted by some kind of peculiar attraction, and he broke out of his control and quickly poured into the metal rod.

Then, the lilac flame simulated by the mana suddenly cooled down to a dark blue.

"Baron, I'm already working my mana at full capacity, but the speed at which I transform my mana has reached a certain extreme. No matter what I do, the mana drain rate will no longer increase."

Lawson understood, "The upper limit of mana conversion is extremely low."

"yes, it's sadly low."

He snorted at the metal rod in his hand.

"Just this big treasure, you can only transform up to six parts of mana per second."

"When you channel with a portion of mana, the conversion efficiency is as high as 600%. One mana you input can be turned into seven parts."

"But if you use two parts of mana, you will immediately exceed its transformation limit, and the mana that flows out will only be eight, and it will still only be six parts more."

"Then, it can't run on its own, and it must be guided by a mage at all times."

"In the end, it seems that the increased mana can only be used to restore the mage's mana, but it cannot increase the upper limit of mana, that is, it cannot replace meditation."

Rosen understood that such performance was far from his requirements, even to the point where it could not be applied.

At a glance, six parts of mana a second, and a mage has been guiding, it's like exchanging a pound of gold for a pound of, stupid.

But that can't be the case.

Everything must be solved first, and then we can continue to think about whether it is good or not.

Lawson immediately went into focus.

"So, is there a way to increase the maximum number of conversions?"

Obviously, the maximum conversion volume must reach a certain level for there to be room for application.

Phoebe nodded her head.

"After preliminary research, it was found that the maximum conversion efficiency was maintained at 600% and could not be improved, but the wider the cross-section of the round bar, the greater the amount of mana conversion."

"Doesn't it have anything to do with length?"

"The length only affects the additional loss of mana conduction, and has little effect on the maximum conversion amount."

It's a little deviant, but Lawson understands.

"Anything else?"

"No. It's too short a time to do it yet."

"Is there a simple linear relationship between the maximum conversion amount and the increase of the cross-section, or is it something else?"

Fibbit shook her head, "Not sure yet. Why don't you start now?"

Lawson immediately said, "Okay, let's get started."

Since the cross-sectional area can affect the amount of mana conversion, let's study this first.

The two were busy from noon to late at night, and finally came up with a very strange one

Conclusion.

Fibbit looked at the relationship curve and was speechless.

"Is there a mistake?"

This relationship curve is like a ghost drawing.

Not to mention the large shocks mixed with countless small shocks, they are also proportional and inverse.

At first glance, it seems that there are some rules, but if you look closely, you can't summarize it, and it's very confusing.

Fibbit spread her hands helplessly: "This is so hateful. Why don't you change the name of it to Titan Magic Iron?"

Rosen didn't speak.

He stood by the curve, one hand around his chest, the other supporting his chin, and fell into a long contemplation.

Looking at it, he suddenly had an idea, and immediately immersed himself in the magic virtual machine, made up a model, threw it into the computing core and started running.

Run one, find that the curve does not match the reality, immediately fine-tune and then run.

After that, he kept running the model, and in the eyes of others, he was as motionless as a sculpture.

In the blink of an eye, it was one o'clock in the morning, and Fibbit couldn't stay up and was reluctant to rest.

Because he was very curious, he wanted to see if Rosen could use his unparalleled mathematical ability to see through the rules.

So, I just laid a bunk and slept directly in the laboratory.

On the other hand, as the model is improved over and over again, the parameters are corrected over and over again.

When a rooster crows in the sky, Rosen got a rather beautiful system of nonlinear multidimensional flow equations.

It's no simpler than a system of generalized field equations.

According to this equation, when the Titan Divine Iron is in the shape of a round bar, the diagram of the relationship between the maximum conversion amount and the cross-section is such a "ghost drawing".

The calculated curve fits perfectly with the actual curve.

Rosen is not really guessing, it is the result of careful analysis.

Because the metal round bar is a simple metal element, and the microstructure is a homogeneous metal crystal that is simply stacked regularly, the only variable is the cross-section.

The law is certainly relatively simple, and it is impossible to behave so complexly.

Then, this complexity must come from the mana itself, that is, the rules of mana operation.

More precisely, it is Rosen's high-level mana rules.

The rules of mana are complex and multi-dimensional, and a large amount of information is compressed into a two-dimensional coordinate system, which naturally seems very confusing.

Of course, if there is no supercomputing power of the computing core as an aid, it is estimated that it will be possible to calculate a hundred years by relying on the hard calculation of the human brain.

It's not necessarily right.

In short, Lawson relied on super computing power to calculate the conversion law of this Titan Divine Iron.

But in the end, whether it is right or not, it is necessary to design the optimal form of the Titan Divine Iron according to the laws described by the equations.

If the final results are still in good agreement, then there is basically no big problem.

There is a molten gold cauldron in the Elemental Laboratory, and Lawson has not slept all night, but he is not tired at all.

Supported by a strong curiosity, with the ability to cast 12 stars, he independently fused the Titan Divine Iron into the optimal shape in the calculation.

The shape is very complex, very precise, resembling a multi-layered ellipsoid.

In short, if you don't figure it out, you're never going to be able to create something like this just by imagination.

Even if it resembles it, it can't get the essence.

Because of the complexity of the mana rules, even a slight error may cause a chaotic mutation in the final function.

From "excellent" to "extremely poor".

Just as he was preparing for the experiment, a Phoebit voice came from behind him, "Baron, why is it like this?"

He woke up, and when he saw the precision hollowed-out ellipsoid, he immediately smelled a law.

But what the specific law is, he doesn't know.

Rosen replied not as asked.

"The Titan Iron is truly a great gift from the Creator to mortals. Not only does it have a natural tenacity effect, but it also has a strange memory effect that is extremely resistant to deformation caused by external forces."

Talking, Rowe

Mori held a metal ellipsoid in both hands, and his five fingers were spread out, pressing on the calculated special mana contacts.

"Sir, please release the breath of fire on this ring in the center."

"Be careful, it's just a ring, try not to leak your strength."

Fibit immediately complied.

As the blue-white mana flame wrapped around the metal ring in the center, Lawson began to operate the mana.

In the next moment, the blue-white flames disappeared without a trace.

The maximum conversion volume has reached an amazing boost.

Rosen's thought moved, and he blessed himself and Fibit with a high-level thorn shield.

"It's not enough to reach the limit, breathe in low-level flames."

Fibbit complied.

As a result, low-level spells were also extinguished.

Phoebit was also very wild, relying on the spell to protect his body, and immediately changed to a high-level fire dragon breath with low dexterity.

Deep blue high-intensity flames sprayed on the metal ring.

Lawson also used his mana with all his might, and immediately felt that the mana he had consumed due to casting spells was increasing at a violent speed, and at the same time, the dark blue flames suddenly turned dark red.

Almost extinguished.

"It's the limit.

"Under harsh preset conditions, the maximum conversion amount is the mana power of a standard high-level spell per second, and the conversion efficiency is 850%."

In other words, Lawson can pry a high-level spell with the consumption of a low-level high-level spell.

Fibbit's scalp was a little fried, and he couldn't figure out why there was such a qualitative leap.

He looked incredulously at the openwork ellipsoid, and asked the original question again.

"Baron, why is this weird?"

Rosen took out the pen and paper he had with him and wrote down the equations he had guessed.

"I did the math overnight."

Fibbit glanced at the manuscript paper and was dazzled by the various symbols on it.

He is a very good experimental mage, with strong hands-on ability, but his mathematical skills are a mess, and when he first arrived, he was only slightly better than the four operations.

Although I have learned the number of streams now, it is only a beginner.

So as soon as I saw such a complex system of equations, I felt the abrupt jump of the blood vessels in the forehead.

He asked with difficulty, "How...... How?"

After asking, I realized that I had asked a stupid question.

Rosen raised an eyebrow and asked, "Sir, are you sure you want to listen to my explanation?"

"Forget it, it's not my field. If only you knew how to do it."

To figure it out, he felt like he might have to lose ten years of life.

Rosen said, "This conversion ellipsoid is already available."

"In my calculations, by tripling the size and adjusting its shape, you can increase the maximum conversion amount to five high-level spells per second. But at the cost of reducing the conversion efficiency to about 620%."

In other words, they have successfully plucked the power fruit from the Elemental Tree!

It's beautiful, but the Titan Divine Iron seems to be very difficult to handle.

Fibbit asked, "Baron, what are you going to do with it?"

"To be the core of the power of a high-speed hovertruck."

"But this thing is just a transformation power, and it can't be created out of thin air."

"Is the Baron going to make a stove on the hovercar? Or do you want to be exposed to the sun?"

His grasp of environmental power is very accurate, and he feels that neither of them can be used, and I am afraid that it will be difficult to provide enough power.

Rosen smiled slightly, "Actually, I know a spell called 'Heavenly Light', which can channel sunlight very well."

"I'm going to draw a large area of sunlight and use the lens set to focus on the core of power...... Hmm, but how much is needed and how the optimal structure should be designed needs to be calculated."

"Anyway, Sir, you can help me get as many Titans as I can, and then I'll build a hovercar, no, I should call it a miniature floating city."

「

I'll drive it to the Imperial Capital and let everyone know what we want."

Fibbit immediately said, "Okay, I'll hand over the Titan Divine Iron!"

Rosen was in no hurry to leave.

"Sir, I also need a material that is malleable before petrification, and very tough and light after petrification. Of course, it's better to be cheaper."

"Do you have any recommendations?"

Fibbit thought about it and found something from his collection.

"For an alloy of pure gold and iron, only 5% pure gold is mixed with wrought iron. Wrought iron will become as foamy as fermented flour, swelling four or five times larger, and will become as soft as mud, and ordinary low-ranking samurai can knead this alloy with their hands like mud."

"That's why I call it bread iron."

"And after using your high-level petrification on this bread iron, it immediately becomes very hard, about seventy percent of the Titan Divine Iron."

"As for the price, the price of pure gold is 100 kroner for one dila, and the current price of wrought iron should be 5 kris for one dira, and if you get a bread iron for 1,000 dila, you can make a carriage for an ordinary carriage. It's less than 1,000 crowns."

"Hmm~ That's a good thing."

Lawson was going to use this bread iron to build the body of his hovercar

"So, is there anything else I need to buy from out of town?"

Fibbit immediately said, "Of course."

"I've heard that there's an ironworks on the shores of the Great Golden Lake, and all the slag produced in it is used to pave roads."

"It's a waste!"

"You can help me buy the slag back, the more the better."

"Slag...... There may be good things in it. Well, I'll have people collect the slag from the refineries in various places, and bring it all over when the time comes."

Fibbit smiled: "Okay, good, the more the better~ There is no cap!"

Rosen left the Elemental Lab, and after a moment's shift, he entered the nearby Life Lab, and after finding Vivien, he asked the same question.

"What do you want me to bring for you in the Imperial Capital?"

Vivien thought about it carefully and said, "The Imperial Capital has a great alchemist named Nailofa, if you can get me his alchemy notes to show me, then I will be satisfied."

Lawson spread his hands, "It's a real problem, but it's on me."

Vivien happily gave Rosen a fragrant kiss: "Honey, your ability is much greater than my brother's, then I'll wait for your good news~"

After leaving the Life Lab, Lawson returned to the Lord's Castle, first drew up a list for the attendants to collect the materials for the hovercar, and then dealt with the next administrative affairs, and then returned to the backyard.

For some time afterward, Lawson focused on building high-speed hovercars.

The principles are all there, and the specific design is helped by the computing core, and it is also quickly done.

In addition to the fact that the Titan Divine Iron is somewhat insufficient, other materials are also cheap, the difficulty of building is also low, and there are many refining helpers, so the progress is very fast.

It was done in less than twenty days, and I thought I could go directly, but there was another unexpected news.

Master Sophia fell ill, not a serious illness, or an ordinary cold.

Although Vina treated her in time, she was still very weak and old age.

In such a situation, it is obviously not suitable to go far away.

When I visited the patient, I saw Master Sophia lying on the hospital bed, her weak face full of apologies.

"Lawson, I can only let you go to the imperial capital alone, but I saw your hovercar, the speed is very fast, as long as you rush at full speed, no one can catch up with you."

"You should be safe on the road. When you get to the imperial capital, go directly to Buren, and he will take care of you."

What else could Lawson say, so he nodded, "Okay, master, I will."

"Apologize to Your Majesty on my behalf. If he wants to see me, you can paint him a picture of me. When you come back, draw me a portrait of Your Majesty."

"Okay."

"Then you go

bar. Don't worry about the territory, I'll show you."

Rosen thought about it, with the presence of the master, he would have no worries, so he carefully told her about the situation of the ice dwarves and the worries of a possible invasion, and also talked about his strategy.

Sophia listened carefully, then nodded, "I've counted, just give it to me."

"You have to be careful when you go to the imperial capital, because all famous mages will be invited, and so will Archmage Horenir, don't conflict with him unless you have to."

"Okay."

After everything was explained, Rosen left Sophia's room to make final preparations for the trip.

After a while, Thrandis came over to chat with Sophia every day.

"Master, how are you doing?"

Sophia's eyes blinked, "I'm fine."

Thrandis was taken aback: "Huh?"

Sophia "shh

"Besides, I'm so old, and I've been cursed by my soul, and I'm in one place, so my body is naturally fine. If you run around, you're going to get sick."

She especially recognized the bed, she had just come to Crescent Town before, and she hadn't slept well for a week, but now she finally got used to it, and she didn't want to toss again.

Thrandison understood, "Okay then."

On the other hand, Lawson also felt that things were a little strange, and vaguely guessed something, but he couldn't say anything through it.

Since the master is not in the same line, considering the high speed of the hovering car, and considering that the emperor is a place blessed by the real gods, he simply did not bring a single guard.

He only brought items that had been prepared in advance for display at the university meeting and some simple luggage, and hurried alone.
