Early the next morning.

The hall on the first floor of the Lord's Castle.

In front of the princess and O'Brien, Rosen calmly said the decision that had been discussed for a long time.

After speaking, Master Oberline's brows furrowed slightly, feeling that this method deviated from tradition, and was about to refuse, when the voice of Princess Haley Soya came from beside him.

"Mayor Lawson, your proposal is good, so let's do what you say first."

O'Brien was stunned, and looked at Hayley Soya, only to see that the other party's face was calm and unwavering, and he couldn't see what she was thinking at all, and his heart was shocked.

After thinking about it carefully, he guessed a possibility, and swallowed back the words that rushed to his mouth.

"Since Your Highness agrees, I have no opinion."

They were all big shots, and they had a lot of business to attend to in Winterfell City, so naturally they couldn't stay in a small remote place like Crescent Town for too long.

After breakfast, after a short rest, I used my flying skills and soared into the sky all the way back to Winterfell.

Leaving Crescent Town far behind, O'Brien finally couldn't help the confusion in his heart.

"Your Highness, with all due respect, I'm afraid the Duke won't agree to your approach."

As long as you are a nobleman living in Winterfell, everyone must master a skill, which is to carefully find out the Duke's temper, so as not to violate his taboos and lead to a rough fate.

O'Brien, as a master refiner, can become the vice president of the Lafalella Academy, and this skill has naturally been perfected.

So I felt that Princess Haili Soya's decision was inappropriate.

Hayley Soya glanced at the refiner lightly, "I know it's wrong, but my father doesn't have time to care about such a trivial matter."

"As long as you don't say anything, my father won't know about it, or is the master going to expose me to my father?"

With that, Hayley Soya narrowed her eyes and stared at O'Brien.

O'Brien's heart tightened, and he immediately shook his head: "No, Your Highness, you are the head of the Academy, and your will is the final decision of the Academy."

"Hmm."

Hayley Soya's expression softened and explained softly.

"I know it's a bit against tradition and against my father's dignity. But war is coming, and my three elder brothers are great warriors."

"When war breaks out, they will be put to good use and will have plenty of opportunities to build up their exploits. And I, as a high-level peak mage, if I don't want to lose the opportunity, I must find another opportunity to rise."

"Master, please remember that this is not only my chance, but also the Academy's chance, and even more so the opportunity of the Northern Mage."

"If I can inherit the throne, I will greatly tilt my interests in favor of the mage world, and I will also greatly improve the status of mages, instead of being commanded by that group of rude and savage warriors as I am now."

The status of the highland mage is noble, and that is because the high lord is the archmage. Mages of Winterfall weren't so carefree.

Not only is it not free, but it is even a little aggrieved.

Oberline's heart shook again, and he nodded slightly.

"Your Highness, I fully understand your intentions. Rest assured, Lea and I will keep it a secret."

As a mage, he naturally also supported Princess Hailisoya's ascension, in fact, the entire Rafferea Academy supported it.

It's a pity that the academy has limited energy.

After flying a little more, Princess Haley Soya said, "I ask you, after getting Rosen's spell lock, can you crack his spells, especially this petrification?"

Although Lawson is promising, no one in the upper echelons will bet on one person.

Otherwise, the superior is not the superior, but a puppet manipulated by his subordinates.

Therefore, it is necessary to spread out the bets and let the subordinates check and balance each other.

But unexpectedly, when she asked like this, O'Brien's brows furrowed.

Hayley Soya was perceptive: "What? He gave you something fake?"

O'Brien shook his head, "It's real, but it's weird."

"Even if I knew, I wouldn't

The only way to break his existing spell lock is to use this spell lock to encrypt my own spells."

Seeing that the princess was puzzled, he explained, "This spell lock is like an irreversible knot that cannot be untied if it is killed."

"In fact, if I use this spell lock to encrypt my spells, there is a good chance that Lawson will not be able to unlock them."

Hayly Soya frowned slightly, "Then let's go back now and ask Lawson for the principle of petrification."

O'Brien shook his head: "Your Highness doesn't need to bother, although I don't know the principle, I can still copy it directly, it just takes some thought."

"If Your Highness needs it, my refining workshop will be fully operational, and I will be able to produce 5,000 petrified staffs in a day."

This answer satisfied Hayley Soya.

She asked, "Do you think that you can develop on the current petrification technique and develop a high-level or even master-level petrification construction technique?"

The currently released building petrification is a mid-level version, which is naturally good for ordinary buildings, but for real military fortresses, the strength is a little insufficient.

Naturally, the stronger the military fortress, the better.

Oberline's face suddenly showed embarrassment, and although he didn't want to admit it, he finally shook his head.

"Your Highness, Mage Lawson is probably one of the strongest logic mages in the North. When it comes to refining, I think I'm standing at the pinnacle of the North, but when it comes to creating new spells, you'll have to look at him."

Hayley Soya wondered, "Isn't it possible for the master to improve on this foundation?"

"Yes, yes, but I'm old, and I haven't fully learned the flow number, so it's really difficult to study a new spell based on the high and deep flow number."

Hayley Soya understood, so she said, "Then you don't rob Lawson's petrochemical construction business, let him make money."

O'Brien himself didn't want to grab the menial work of building.

He took a fancy to the spell lock itself, because he was also deeply troubled by the plagiarism of his peers, and when he heard this, he smiled bitterly: "Your Highness, to be honest, it is difficult for me to rob it."

"I'm afraid it won't be long before Mage Lawson introduces more difficult spell locks, as well as more advanced and powerful petrification."

"He's a brilliant mage, young and strong, and full of energy, and I can't compete with him as an old man."

Hayley Soya laughed, "Yes, he's very young and ...... Be strong."

But when I thought of last night's incident, there was a slight tingling in my left chest.

She thought to herself, "If I wait for more than ten years, I guess I can really become my good helper, and if I am truly loyal, then I can really fulfill the reward promised last night."

Not to mention the three who left, their eyes returned to Crescent Town.

Rosen and Gendelloni are busy working in the alchemy lab.

Despite Sir Mason's arrogant attitude, the equipment produced by the precision balance is indeed much better than the equipment in the North, and it is completely the product of two eras.

At this time, Rosen was slowly scooping up a viscous, pure, transparent liquid that emitted a faint red glow from the temperature-controlled furnace.

This is melted glass.

Gendeloni stood by and looked closely, then shook her head.

"No, there are still subtle bubbles in it, and the color is not pure, and it still has some greenery."

Rosen saw it too, and put the molten glass back into the furnace.

"Both of these issues must be completely resolved."

Gendeloni thought about it carefully, and asked strangely, "Why do you have to glass, the best foundation stone for refining can meet your requirements."

Rosen had his own considerations: "Two reasons."

"First, the glass is hard enough to resist wear and tear much more than the cornerstone."

"Second, glass is cheap, materials are everywhere, and it costs less than one percent of the best cornerstone."

"Even ultra-high-purity, homogeneous colorless glass costs less than one-tenth of the cost of a pure cornerstone. And if we can get this kind of glass and use it to build optical devices, then we have a huge cost advantage."

Optical instruments are a new field that Rosen intends to enter.

The initial stage in this field is not difficult, the cost is low, but the impact is huge.

With this, it is equivalent to opening a pair of deep insight eyes to explore the deep mysteries of the world, which can greatly accelerate the pace of progress.

Gendelloni understood, "Then go ahead and try."

The two continued to be busy.

To be honest, Rosen actually knew a lot of earth methods for making high-purity glass, because he had it in his past life memory.

But knowing is knowing, but practice is the first time, and the nature of the otherworldly glass is also slightly different from that of the earth.

So, you have to grope over and over again.

Over the next few days, Rosen and Gendeloni spent almost all of their free time poring over glass craftsmanship.

In the blink of an eye, three days passed.

The problem has finally been completely solved.

When a pure, colorless, crystal-like glass appeared in the alchemy lab, Gendeloni couldn't help but stare at it, a hint of blurry color flashing in her big eyes.

She sighed from the bottom of her heart: "It's so beautiful~ more beautiful than flawless crystal!"

She looked at Rosen with admiration: "Rosen, I have to say that you also have an outstanding talent in refining, and you have an incredible sense of insight and smell in your grasp of material properties."

There were so many exquisite and original processes that she couldn't think of, and they came out in a few days, just like the creator.

She felt like she was beginning to adore Rosen.

After finally calming down, she couldn't help but ask, "Lawson, what about then?"

The glass in front of her was square, and she couldn't think of its specific function other than being beautiful.

Lawson smiled slightly, and was using the gravitational disintegration technique to create various delicate mirror grinding powders, and said with a smile: "Then grind into reading glasses."

Glass has long existed in the world, monoculars have appeared for more than 30 years, reading glasses are even more popular, and the process of grinding lenses is also quite mature.

Of course, whether it is polished well or not is a very test of technique.

Gendeloni understood, "Oh~~ I see, you're planning to take a high-performance telescope?"

Without thinking, Lawson shook his head: "It's a kind of observation mirror, yes, but it's not a vision."

"Huh? So where are you going to see what?"

She hesitated for a moment, then thought of a possibility.

"You're not going to make the microscope that Khlevin conjectures, are you?"

Hlevin is a mirror master in the East, the founder of the "Far Looking" workshop, and the inventor of the monocular.

While building more telescopes with excellent performance, he gave a prediction.

He said that glass is a master of manipulating light, and since it can pull distant objects into view, it can hold nearby objects larger so that the subtle structure of matter is revealed.

Subsequently, the master mirror began to study microscopic mirrors.

But heaven does not grant people's wishes.

About ten years ago, that is, the third year when the master began to study the microscopic mirror, at the age of 78, he was summoned by the gods to go to the kingdom of God, so the matter of the microscopic mirror was temporarily shelved.

Naturally, Rosen also knew this allusion.

He smiled and nodded, "You guessed it."

"So do you think of how to do it?"

"I thought of it. Help me build these metal parts, not for speed, but for precision, preferably within a single hair."

Gendelloni took the drawing handed over by Rosen and looked at it, and nodded confidently, "Leave it to me."

After having pure mana, her control has increased greatly, and she doesn't dare to say anything else, precision is absolutely guaranteed.

While the frames were being built, Rosen began to sharpen the lenses.

Gendeloni looked at it by chance, and suddenly a question came to mind: "Rosen, can we just make the glass into the desired shape?"

In this way, there is no need to grind.

Rosen naturally thought about it, and he shook his head: "Later, Ken."

Yes, but I don't have a complete understanding of the properties of glass now, and I can't control the complex shape."

In the process of high-temperature cooling, if one is not well controlled, the glass will be unevenly distorted, and then the mirror will be wasted.

Gendeloni understood, "Well, let's take it one step at a time."

The two continued to be busy.

Because it was the first time to do it, the progress was very slow, and it was estimated that it would take two or three days to complete.

When the two were busy until dusk, when they returned to the hall for dinner, they found a familiar figure in the hall.

It was none other than Shabolai, the acting lord of Crescent Town.

He was red and proud, and when he saw Rosen, he smiled.

"Rosen, accompany me to Mochizuki Garden tomorrow, I'm going to ask my aunt for marriage."

Rosen thought for a moment: "Since it's a courtship, you have to prepare well."

Asking the daughter of Baron Dumont for marriage, once the matter was made public, it was the moment when the dagger was exhausted, and Fupos had to go crazy.

Of course, as long as the Count was there, it was impossible for Vobos to stir up a storm.

Rosen personally feels that he only needs to be prepared to prevent assassination.
