As the head of the magic department, Wei Ge actually rarely makes medicine herself.

She usually assigns a project, points out a research direction, and then lets her alchemy apprentices put it into practice.

Using this method, she has trained at least 200 apprentices with basic alchemy skills, including many outstanding alchemy talents.

"This Frost Dust was discovered accidentally by an apprentice named Alena."

She said this with a look of satisfaction on her face.

"This Alena is a talented potion master with great potential for growth. The Lord can train her more in the future."

Rosen was also very happy: "Of course I will."

He looked carefully at the dark blue powder in his hand and had already guessed its purpose.

“Using water as the base tempering material is indeed a brilliant idea.”

"If it can be realized, it would be very, very wonderful, but as soon as I heard it, I felt that it would be very difficult."

Turning soft water into solid ice, if this solid ice is useful enough, it will greatly solve the problem of resource shortage on islands.

After all, an island may lack everything, but it will never lack water!

As he watched, Rosen had a bad feeling.

“This powder should be very expensive, right?”

Wei Ge showed a trace of embarrassment on her face: "It is indeed not cheap. It costs more than 300 Ogg to harden one ton of water."

It is indeed quite expensive, but after mass production, the cost should be much lower.

"What about the strength of hardened water?"

"Well, this is a bit complicated. Depending on the added auxiliary materials, it can harden in many completely different ways. But it mainly has two directions."

Rosen's interest grew: "Show me."

Wei Ge did as she was told immediately.

She took a large glass of water, about one liter, and poured a small portion of dark blue frost dust, a large portion of pitch-black powder, and a small portion of a white viscous substance similar to grease into the water.

She began to stir vigorously: "The black one is charcoal powder, and the white one is alkalized sheep fat. They are auxiliary ingredients, and their total weight is less than one-tenth of the water."

After stirring for about a minute, the clear water in the cup turned black and became very viscous.

"Pah~~"

Wei Ge poured the sticky substance out of the cup, rubbed it gently with her hands, and it became a black ball. She then threw it gently on the table, and the thing bounced up and down with a "plop plop".

“This is the first hardening direction. As long as you add charcoal powder, yellow powder, lime powder, in short, soft basic elements, it will become this soft and elastic thing.”

"The effect lasts for a long time, usually more than three hours."

"If I use the Lightning Permanence Technique again, then even if I don't recharge it, I think it can easily last for more than 20 years."

"Of course, there are disadvantages, which is that it is not heat-resistant and will melt when exposed to fire."

Rosen took the black ball and examined it carefully, and found that its properties were very similar to those of 'rubber'.

He was immediately very happy. Everyone on earth knows that rubber is a great treasure.

He praised loudly: "Good stuff, really good stuff. This hardening direction is very good!"

"What about the other direction?"

Wei Ge continued to demonstrate: "The other is to use hard basic elements, preferably metal elements as auxiliary materials."

This time, she chose iron powder as the basic element, and then obtained a piece of hard, steel-gray "ice iron".

"Look, lord. The weight ratio of iron powder to water is 1 to 100. The amount of iron powder is almost negligible, but the properties of the final product are very similar to iron."

After a careful inspection, Rosen found that it was indeed the case: "The strength is about the same as wrought iron, it is softer, and the density is very low, less than one-fifth of iron."

"If it could be stronger, it could be used as a building material, or even a good material for shipbuilding."

Even if it cannot be used as the main strength structural part, it should be usable as a covering part or an unimportant auxiliary structural part.

This will greatly save the amount of precious materials and thus greatly alleviate the shortage of island resources.

Wei Ge smiled bitterly: "At first glance, it is indeed good."

"But the stability in this direction is very poor. The tempering effect can only last for half an hour, and the thermal and light stability are extremely poor."

"Even after the lightning becomes stable, its stability is far inferior to that of tempered clay, even less than one-tenth."

Rosen patted his head gently: "Hmm~~This shortcoming is indeed a headache."

“Do you have any directions for improvement?”

Wei Ge nodded: "We need to deepen our understanding of various basic elements, especially pure water."

As she said this, a look of obsession appeared on her face.

"Pure water is an element with extremely complex properties. It is also a bridge between life and non-life. The more I study it, the more wonderful and powerful it becomes."

A trace of regret immediately appeared on her face: "Unfortunately, my understanding of pure water is very superficial, so in the field of hardening pure water, I can only do this much for now."

Rosen listened thoughtfully.

When it comes to his understanding of the physical and chemical properties of water, he naturally has a very deep understanding.

But in this world, pure water has unique magical properties, and these magical properties are extremely complex, even unfathomable.

In this regard, there is an expert who is more powerful than Rosen.

There is no doubt that 'hardened pure water' is enough to create a whole new field of materials science. If it is well developed, all kinds of wonderful new materials will emerge in an explosive manner.

Therefore, this is a new field that is worth spending a lot of money to explore.

After thinking it over, he said, "Wait a minute, I'll get a pure water expert."

After saying that, he rushed to Banshee Port in the East China Sea, boarded a speedboat, and headed all the way to Hank Island, where he took the Banshee Queen Laertris with him, and without saying a word, he brought her back to Vigo's potion room.

At this moment, the Banshee Queen had naturally put on her dress.

As soon as she saw Wei Ge, she squinted and said, "Rosen, Chunshui told me that you have conquered this young lady many times."

Wei Ge's face suddenly turned red, and she managed to keep her composure: "Lord, who is this?"

"Lily, the Banshee Queen of Hank Island, is probably the most powerful pure water mage in the Natural Alliance."

Laertris shook her head. "I can't say I'm the most powerful. When it comes to the precise control of pure water, I can't compare to my mother."

Then he explained, "My mother is in the Flying Fish Islands outside the East Golden Cape. She is not doing well right now."

Rosen immediately said, "Perhaps you can ask your mother to bring the sisters to the Triangle Sea."

"I thought so too, and I have already sent her an invitation. I just don't know if she will agree. After all, she is a very proud and strong-willed woman."

After a pause, she clapped her hands gently and said to Wei Ge: "Show me your Frost Dust."

Wei Ge demonstrated it immediately.

Laertris said nothing. She carefully felt the entire process of change.

After watching for several hours, and waiting for the solution to soften back into water, she said, "I don't know much about the tempering process, but I can sense that your use of the power of pure water is very crude and has great room for improvement."

"I can sense many directions for improvement, but I don't know how to describe them. Because the way I describe the magic knowledge I know is quite different from the current magic system."

Rosen immediately said, "This is a small problem. We can communicate slowly."

After saying that, worried about delaying Laertris's sleep plan, "Lily, are you going to sleep again this year?"

The latter spread his hands and said, "Of course not. It's such a wonderful world, but I have to go to sleep. How shameful is that?"

He added: "It's boring for me to stay on Hank Island, so why not stay here? It's a good opportunity to learn new magic knowledge."

Rosen was naturally more than happy to do so, but he was also worried that the Banshee Queen would not be able to adapt to the new environment for the time being, so he immediately said that he would also join in the research on the topic of hardening pure water and would spare as much time as possible to come over.

In the following period of time, he fulfilled his promise.

No matter how busy he is, he will come and stay for at least two hours every day.

It's not like he just sits there doing nothing, because he is also a ten-ring wizard and has a very good understanding of the tempering knowledge required for 'hardening pure water'.

So, a genius alchemist, a seven-ring pure water wizard, and a ten-ring steel wizard worked together to develop this new field of materials.

Most of the time, the three of them were focused on studying hardened water. Occasionally, when they were really out of ideas, or when they were in the mood, they would have a big fight.

After about a month of research, the three of them worked hard to basically perfect the basic theory of 'hardened pure water' and explored a large number of new material formulas that could be used.

One of the recipes is called 'Colorful Steel Crystal'.

"Huh~~~"

Rosen looked at the colorful steel crystal sample in his hand with a satisfied smile on his face.

"Lily, luckily I have your help, otherwise I really wouldn't be able to figure it out."

All the materials for this colorful steel crystal can be found on the island, and the cost of one ton is expected to be reduced to 20 Oggs.

Its density is one-fourth of that of steel, and its strength is 90% of that of high-carbon steel. It has excellent stability and processability.

It can replace most steel applications and is much better than tempered black clay.

Laertris's face was also full of emotion.

"I never thought that this small cup of water would contain so many secrets that I didn't know."

"Many of my previous doubts about pure water have been answered very closely in the past month."

She was referring to Rosen's theory of basic elements.

Wei Ge smiled and said, "It's worth celebrating."

Laertris asked, “How do we celebrate?”

Wei Ge bit her lip lightly and looked at Rosen: "That depends on the lord's intention."

How could Rosen not understand what this meant? Then let's celebrate.

After celebrating, he asked Laertris: "Should we go back to Hank Island or continue to stay in the Magic Center?"

"Of course it's here. I'm going to start studying all kinds of new knowledge seriously."

Rosen naturally supported: "I'll arrange it for you right away."

After carefully arranging the Banshee Queen, Rosen boarded the third-edition electric carriage and, escorted by Alia and other guards, headed back to Crescent Castle.

On the way back to the city, he suddenly discovered that there were many tempered clay buildings in Crescent City. The streets were much cleaner than before, and there were a lot of pedestrians on the streets, even a little crowded.

At the same time, large residential areas appeared on the plains outside Crescent City. Most of the new buildings were made of tempered yellow clay, with a simple and practical architectural style.

It actually made Rosen feel a little bit of the city in his previous life.

He felt relieved: "At least I have changed this island."

Just as he was sighing with emotion, the telegraph machine in the car suddenly rang, and the intelligence assistant wizard in the front passenger seat quickly translated the code.

After the translation was completed, he turned around and reported: "Lord, Sturgeon Harbor reported that three wizards with unknown intentions came, suspected to be Chao's spies."

Rosen's mind moved. He had set up multiple "Detection Guard" seals at the port, and they were updated from time to time to ensure 24-hour no-blind-angle monitoring of incoming personnel.

At this time, Lai Fu was immediately asked to call up the screen and examine it carefully.

As he watched, the corners of his mouth curled up slightly: "Heh~~ Are you playing Mission Impossible with me here?'

"Send a telegram back and invite them all to the Sturgeon Mansion."

After he finished speaking, he sighed in his heart: "I am now gradually entering the sight of the world's big players."

As its size continues to grow, its impact on the world will naturally increase, and gradually it will become impossible to hide.

This is inevitable, and he has made full preparations.
