On the way back, Rosen was in a good mood.

I feel that this mermaid lord's character is very good, not savage, and reasonable.

In this way, as long as you pay attention to the use of some means, Moby Dick Island can take advantage of its high civilization and domesticate the sea fish people into fish farmers little by little.

In short, the archipelago's marine ranching is just around the corner.

But then again, flowers are not popular for a hundred days, people are not good for a thousand days, and we must also beware of the other party turning their faces for unknown reasons, so we still have to continue to develop countermeasures.

As he was thinking, the Green Communication Jewel rang out, and Harrick's voice rang out.

"The lord ~ the lord ~ has come with a batch of distinguished guests."

Rosen was stunned: "What is the identity?" ”

Harrick immediately reported his name: "They are His Royal Highness Orogaard and Master Nailofa from the Imperial Capital. ”

"Oh, what a distinguished guest, I'll be right back."

He could probably guess the purpose of the two of them coming to the island, and he smiled in his heart.

"I know that you don't have the ability to build planes, so you have to come and beg me."

Of course, the face should only be unaware.

Moby Dick Island is small, and after a while, Lawson is back above the Governor's Palace.

I saw the Royal Sky No. 2 parked in the square, which was the one he built for the prince.

When the square was renovated, the need to park multiple planes was taken into account, and it was made very spacious, so it was natural to park at this time.

After landing and stopping, Harrick came to a quick stop.

"Lord, it's in the VIP reception room."

"Understood, you go get busy, I'll take care of it."

Harrick nodded, then turned back to his office study.

Lawson strode to the VIP reception room.

From afar, I saw the door open, and several attendants stood by the door, ready to wait.

Considering that the person who came was extremely noble and was also his big benefactor, a warm smile appeared on Rosen's face.

Before the person arrives, the voice arrives first.

"Ahaha~ I said, how can the wind and the sun be beautiful in the beginning of spring, it turns out that there are distinguished guests coming to the door~"

When I came to the door, I saw that the prince and Master Narofa were both standing up, and they both had warm smiles on their faces.

The prince Orogaard walked a few steps quickly to meet him, and praised him heartily.

"Lawson, I really didn't expect that after a few months of not seeing each other, you would completely finish this archipelago, it's really amazing!"

He had just flown around the island and found that construction was being carried out everywhere.

Curious, he found another place to land quietly, and together with Nailofa, he found a few people to ask, and he probably knew what Rosen had done in the past.

It can only be said that this guy Rosen is not only a genius in magic, but also has amazing management ability.

For the second prince, a comrade-in-arms who worked hard together, Rosen naturally did not hide it.

He smiled slightly: "The main reason is that the local nobles welcomed me warmly, so I responded warmly." ”

Orogaard laughed, "That's really warm enough." ”

Moby Dick Island is relatively closed, and the local family does not have any reputation in the Golden Land, so at this time, it was killed by Lawson in one go, and it did not cause any waves in the inland of the Golden Land.

The prince also felt that this was very normal, and it was a matter of course to be punished for rebellion.

Soon, a few people sat down again, and then went straight to the point.

Master Nerofa took out a piece of the Mystic of the Stars Crystal and handed it to Lawson.

"This is a gemstone that I spent a week synthesizing, weighs 50 fosa, and the quality is hard to describe."

Lawson took the gem, tested it with mana, and estimated it according to the volume, and found that the proportion of perfect resonance cavities in it was ten percent.

That's pretty good for a natural gemstone, but a perfect gemstone that resonates almost 100% with Lawson isn't at all a level.

Rosen examined the gem again and knew what was wrong: "The master's shaping technique is not precise enough, right?" ”

Nerofa sighed: "I tried my best, but both the crystal volume and the quality reached my limit. ”

Orogaard pointed to the gem in Lawson's hand: "This gem can probably store mid-level and high-grade mana, which is not bad, but it is completely insufficient to drive flying magic weapons." ”

"My father took into account the opinions of many alchemists, and believed that the refining of perfect gems is very difficult, and although it can be partially overcome by cultivating professionals from an early age, it is obviously not something that can be solved in a while."

"And in fact, when it comes to building airplanes, there are too many of them to count."

Speaking of this, a deep sadness appeared on Ologaard's face.

"Master Lawson, the production of flying magic machines has encountered many, many problems."

Rosen knew it, but there was a look of concern on his face: "Your Highness, what are the specific problems?" ”

A self-deprecating and helpless smile appeared on the face of Narofa on the side.

"I think it's okay to say, because it's more concise."

Ologaard spread his hands: "My uncle is right, to be precise, everywhere is a problem. ”

He began to give a detailed briefing.

"According to the refining book you gave, more than thirty refining masters work together, each in charge of a field. After several months of busyness, the finished products have also been produced. ”

"We tried to put all the pieces together and put together a complete artifact."

Rosen proposed, "Your Highness, we are used to calling this flying magic machine an airplane. ”

"Airplane~~ Oh, it's easy to remember, so I'll say the same."

He continued: "In short, the plane is spelled out. ”

"You can fly, but you can't fly fast, and you can't fly high."

Rosen comforted again and again: "Your Highness, it's the first time like this, just come a few more times." ”

Orogaard was not comforted at all, but smiled wryly.

On the side, Narofa said: "This is already the fifth prototype, and the first four can't fly!" ”

Lawson was very happy: "That's not good, it means that each time is better than the last." ”

Orogaard rubbed his forehead: "It's continuous progress, but the refining masters are relatively old, and after continuous high-intensity work, they all fall ill. ”

"Let's talk about the fifth prototype, the fastest speed is 120 semis per second, and no matter how fast it is, it will be powerless."

"When flying to extreme speed, the fuselage will still 'cluck', as if it is going to fall apart in the next second, and it will shake uncontrollably, and I dare not do all kinds of rolling maneuvers."

"Also, the communication gem has also been made, but the noise is very loud, and the effective communication distance is only 30 meters."

Speaking of which, Orogaard was too lazy to say more.

On the side, Naelofa began to add.

"There are also machine guns, the shells are not powerful at all, and they are not smooth, they are either jammed or blown up, and they almost killed the test mage."

"That's right. Because of the shape error of the fuselage, the glass is not tightly installed, air leakage, hiss, and it will pump out, and it will be out of breath after driving for a long time. ”

In the end, he spread his hands: "In short, the distance is really usable, and there is no end in sight." ”

Orogaard pointed to Sky No. 2 outside the window, with an emotional expression.

"The plane you built is a genuine dragon-slaying artifact, imitated by the Royal Workshop, it is a sick bird, and it is not a product of the era at all."

"Master Rosen, do you have any solution?"

Rosen spread his hands: "I can only say that there is only one way, and that is to find the genius of the precision refiner, and then practice more, preferably from a young age." ”

Why is it so hard?

Because both the core of the god iron and the shape of the aircraft are complex surfaces described by complex functions, it is difficult to meet the requirements by relying on the human brain.

The best way, naturally, is to develop chip-controlled precision CNC machine tools to assist, which will not be possible in a century.

Lawson didn't have the ability to do that either.

The method of that level is to find a genius in refining, cultivate it from an early age according to the path of precision alchemy, and practice children's skills, which should be possible to meet the requirements.

So, he's not lying, he's giving the right path.

Apparently, Orogaard and Naelofa knew this as well.

At first, they suspected that there was something wrong with the refining book provided by Lawson, but after careful inspection, they found that everything was correct, and it was simply that the refiner's ability was not good.

So as soon as Rosen said that, they agreed.

Orogaard asked, "How long do you think it will take if you focus on training?" ”

"Personally, I feel that if it's really a genius, then there should be five years of dedicated practice to acquire enough abilities to meet the minimum requirements."

"Minimum?"

"It's that after many failures, there may be one success. This success rate is estimated to be around 1 in 5. ”

This is estimated based on the Lotana situation.

After this chief apprentice had been studying precision alchemy for more than half a year, the yield rate of the Shentie core had reached one-twentieth of the total.

Orogaard and Naylofa looked at each other and discussed in a low voice.

In the end, Orogaard said: "Master Lawson, it's better to do this, we are responsible for finding a group of talented young refining mages, let's give 500 people first." Can you help us train it? ”

Rosen agreed.

"No problem. I currently have about 500 relatively mature refining apprentices, you bring them in, and I will arrange them into my workshop, just one by one. ”

"The cultivation fee."

Rosen immediately waved his hand: "What did Your Highness say, what kind of cultivation fee do you want?" ”

"You will send people here, and I will take care of food, shelter and clothing."

"As for me, I will arrange for these young geniuses to enter the workshop to help me build precision magic weapons, and I will also give out a part of the monthly gold as daily consumption."

"I believe that as long as I train in my workshop for five years, I will definitely become a very good precision refiner."

The second prince thought it was very good: "Then let's do it!" ”

He said seriously: "The refining apprentice can spend time cultivating, but the construction of the aircraft cannot be delayed. So, my father's meaning is to buy finished products from you first. ”

After months of practice, I felt that instead of spending a lot of money to build a batch of garbage, it was better to use the same money to buy a ready-made good plane from Lawson.

Rosen perked up and knew that it was time to make money.

He immediately came up with his idea.

"Your Highness, this Sky No. 2 I built for you, every part is made of the best, it costs me a lot of effort and a lot of precious materials, and the price may not be low."

"Also, I don't think it's a good idea to build such a good plane, because it's too expensive to cluster."

Nainofa on the side immediately understood, his eyes lit up, and he gently patted the arm of the chair.

"Rosen, what you mean is to build low-cost aircraft with mediocre performance, and replace quality with quantity."

"That's right!"

Rosen also clapped his hands lightly and explained carefully.

"Your Highness, Master, as long as the cannon is powerful enough, it doesn't matter if the plane is slow, more than a dozen of them are scattered and rush forward, everyone will beat the dragon together, and the other party will die if he doesn't die, right?"

Orogaard immediately nodded: "That's the truth. ”

It was only natural that Rosen launched his own castration plane.

With the hand of the mage, write out two lists at the same time, and hand them to Orogad and Nailofa respectively.

"Your Highness, this is the price list of accessories I wrote, you can freely assemble a pair of one-man miniature planes according to the description above."

Orogaard and Narofa took the list and looked at it carefully.

And it was written.

"2 times the speed of sound, 50,000 crowns. 1.5 times the speed of sound, 30,000 kroner. 1.2 times the speed of sound, 15,000 kroner. ”

"An all-weather insight eye for nighttime observation. Outstanding performance 50,000 kroner, excellent 30,000, ordinary 10,000. ”

"Cannons, 20,000 crowns each, 1,000 crowns for a super cannonball, 800 for excellent, 500 for ordinary cannons."

"Communicator. Large 500 lami distances, 20,000 CZK. Small 300 ram, 5000 kroner. ”

"Energy storage gem."

Written in great detail.

Orogaard soon saw something new: "The eye of insight for night observation? ”

Rosen immediately explained.

"With the new magic results, you can see the ground clearly even if there is no light at all. Living creatures, in particular, are very eye-catching, like looking at candles in the night. ”

"Later, I will give His Highness Sky No. 2 a free upgrade for this function."

Orogaard's heart was moved when he heard this: "This is a good thing~ it is indeed worth 50,000 kroner!" ”

On the side, Narofa asked curiously: "What is the principle of this technique?"

Rosen explained simply: "Master, I stumbled upon that everything with temperature glows."

"When the temperature of the flame is high, it will emit light that is visible to the naked eye, and if the temperature is low, it will emit light that is invisible to the naked eye but can be perceived by the spell."

"At night, the ambient temperature varies, so you can see the outline. Especially living creatures, the temperature is significantly higher than the environment, so it is particularly obvious. ”

As soon as Nainofa heard this, he felt that this principle was correct, and he couldn't help but be impressed: "Master Rosen's insight is really as amazing as it is."

The two continued to watch, and after some discussion, after a while, they saved up a plane.

"2x the speed of sound, single pilot, twin cannons, normal insight eyes, small communicators, small energy storage gems. The total price is 150,000 kroner. ”

Aurogard pulled out the cash box that had been at his feet and put it on the table.

"6,000 Olympic gold coins are here, let's start with 40!"

Originally, I only wanted to order 2 planes, but now it is 40 planes, and I have formed a reliable dragon slaying combat power at once, and I feel that this transaction is particularly worthwhile!

Rosen quickly calculated and found that his profit was about 3 million crowns, and he was happy in his heart and said, "Your Highness, the delivery will be completed in three months." ”

With such a castrated version of the plane, he can have one in two days.

After saying that, he got up and walked out the door.

"Let's go, Your Highness, and I'll equip your plane with an eye of insight with outstanding performance."

"Okay~~ I'll see what kind of good thing it is."

Aurogard followed Rosen to the Doge's Palace Square.

Nailofa was also curious, so he went to see it.

When I went out, I turned my head and looked at the cash box on the table, and sighed secretly: "Selling airplanes is really profitable!" ”

On the square, Lawson divided five by two, and installed the Eye of Insight on the prince's plane.

The prince opened it and tried it, and he liked it immediately, and praised loudly: "Good thing!"

On the side, Nailofa was a little curious about the technical details, and was about to ask, but Rosen had already taken the initiative to explain.

"Your Highness, this is what I have carefully concocted with optical glass and photographic spells, and in terms of precision, it is not inferior to the core of divine iron."

"I will send you the specific refining book with the delivery plane."

Nailo Fateon felt a headache: 'It's a precision magic weapon again. ’

Immediately lost interest in asking.

After that, the prince stayed for a while, so he took Narofa and drove a new plane with upgraded functions to return to the imperial capital happily.

Lawson was about to start building the plane, but another group of visitors came in.

But it is the president of the Mage Guild of Angry Waves City, the peak archmage Raven.

This is a ruthless man.

Before, it was this guy who blocked the gate of Thundering Fort and demanded that the duke pay back, and it is said that the duke did not dare to go out for three days.

A total of three people came this time, and in addition to Raven, two were also archmages.

They are also all civilian archmages who have been invited to participate in the university meeting, one is level 8 and the other is level 7.

Not only are they of high rank, but they are also logic mages.

In short, if these three people join forces, they can even hurt the newly promoted transcendent.

Lawson is even more useless, and he has to kneel as soon as he looks at him.

These three had no friendship with Rosen, and the sudden visit made him feel a little weak, afraid that the visitor would not be good.

But fortunately, there were 200 elite riflemen in the Doge's Palace, all of whom carried thorn runes, and they were holding special Serguin magic guns, and they were rapid-fire guns with 50 rune bullets in ten seconds.

Together, the torrent of bullets that erupted was enough to threaten the lives of the three archmages.

Therefore, Rosen is relatively determined.
