Start with Island Lord

As the head of the magic department, Wei Ge rarely makes medicines by herself.

She usually arranges a project, points out a research direction, and then lets her apprentices make medicines to practice.

In this way, she has trained at least 200 apprentices with basic medicine-making ability, including many excellent medicine-making geniuses.

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

She said so, with a look of satisfaction on her face.

"This Alena is a genius potion master with great growth potential. The lord can cultivate more in the future."

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

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

"Using water as the basic tempering material is indeed a wonderful idea."

"If it can be realized, it is indeed very, very wonderful, but I feel that this matter is not easy when I hear it."

Turning soft water into hard ice, if this hard ice is good enough, it will greatly solve the problem of resource shortage on the island.

After all, the island may lack anything, but it will never lack water!

Watching, Rosen had a bad feeling again.

"This powder should be very expensive, right?"

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

It is indeed quite expensive, but after large-scale 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 has a variety of completely different hardening methods. But there are mainly two directions."

Rosen's interest increased: "Demonstrate."

Wei Ge immediately did so.

She took a large cup 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 white viscous substance similar to grease into the water.

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

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

‘Pah~~’

Wei Ge poured the sticky substance out of the cup, kneaded it gently with his hands, and it became a black round ball. Then he threw it gently on the table, and it bounced up.

“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 you use the lightning constant technique again, even if you don’t charge it, it can probably last for more than 20 years.”

“Of course, there are also disadvantages, that is, it is not heat-resistant and will melt when burned by fire.”

Rosen took the black ball and examined it carefully, and found that it was very similar to the properties of ‘rubber’.

He was very happy immediately. Everyone on Earth knows that ‘rubber’ is a big 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 got a hard, steel-gray "ice iron".

"Lord, look, 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 true: "The strength is about the same as wrought iron, it is soft, and the density is very small, less than one-fifth of iron."

"If it can be stronger, it can be used as various building materials, even a good material for shipbuilding."

Even if it cannot be used as the main strength structure, it should be usable for covering parts and unimportant auxiliary structures.

This can greatly save the amount of precious materials, thereby greatly alleviating the shortage of island resources.

Wei Ge smiled bitterly: "It looks good at first glance."

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

"Even after the lightning is constant, the stability is much worse than tempered clay, even less than one-tenth."

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

"Do you have any direction for improvement?"

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

Speaking of this, she showed an obsessive look on her face.

"Pure water is an element with very, very complex properties, and it is also a bridge connecting life and non-life. The more I study it, the more I feel it is wonderful and powerful."

She immediately showed a trace of regret on her face: "Unfortunately, my understanding of pure water is very superficial, so in the field of hardened pure water, I can only do this level for the time being."

Rosen listened thoughtfully.

As for his understanding of the physical and chemical properties of water, he is naturally very in-depth.

But in this world, pure water has unique magical properties, and this magical property is 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 new field of materials science. If it is well developed, all kinds of wonderful new materials will emerge in a spurt.

So, this is a new field worth cultivating at a high price.

After considering it for a while, he said, "Wait, I'll invite a pure water expert."

After that, he rushed to the Banshee Port in the East China Sea, took a speedboat, and rushed all the way to Hank Island, took the Banshee Queen Laertris, and took her back to Wei Ge's potion room without saying a word.

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

She liked to wear a dark blue silk long skirt, a fine fur waistcoat, and a lace flower hat, looking like a fair and tender lady waiting to get married in a noble family.

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

Wei Ge blushed immediately, and barely managed to keep her composure: "Lord, who is this?"

"Lily, the Banshee Queen of Hank Island, may be the most powerful Pure Water Mage in the Natural Alliance."

Laltris shook her head: "Not the most powerful, I can't compare to my mother in terms of fine control of Pure Water."

After saying that, she explained: "My mother is in the Flying Fish Islands outside the East Golden Cape. She is not in a good situation now."

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

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

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

Wei Ge immediately demonstrated it again.

Laltris didn't say anything, she carefully felt the whole process of change.

After observing for several hours, when the solution softened into water again, she said: "I don't know much about the tempering process, but I can feel that your use of the power of pure water is very crude and there is a lot of room for improvement."

"I can feel many directions for improvement, but I don't know how to describe it. Because the way I describe the magic knowledge I know is not quite the same as the current magic system."

Rosen immediately said: "This is a small problem. Just communicate slowly."

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

The latter spread her hands: "Of course not. Such a wonderful world, I have to go to sleep, what a pity?"

He said again: "It's boring for me to stay on Hank Island, so why not stay here, just in time to learn new magic knowledge."

Rosen naturally wanted it, but worried that the Banshee Queen would not be able to adapt to the new environment for a while, and immediately said that he would join in the study of the topic of hardening pure water, and would spare as much time as possible.

In the following time, he really fulfilled his promise.

No matter how busy he was, he would come here for at least two hours every day.

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

So, a genius potion master, a seven-ring pure water mage, and a ten-ring steel mage worked together to develop this new material field.

Most of the time, the three of them focused on studying hardened water. Occasionally, when they really had no ideas, or when they were in the mood, they would have a big fight.

After studying for about a month, the three of them did their best to basically perfect the basic theory of 'hardened pure water' and explored a large number of new material formulas that can be used.

One of the formulas is called 'multi-colored steel crystal'.

'Huh~~~'

Rosen looked at the multi-colored steel crystal sample in his hand with a satisfied smile.

"Lily, it's a good thing you helped me, otherwise I really couldn't make it."

All the materials for this multi-colored steel crystal can be found on the island, and it is estimated that the cost of one ton can be reduced to 20 org.

Its density is one-fourth of steel, and its strength reaches 90% of high-carbon steel. Its stability and processability are very good.

It can replace most steel application scenarios, which is much better than tempered black clay.

Laertlis was also full of emotion.

"I didn't expect that this small cup of water actually contained so many mysteries that I didn't know."

"Many of my doubts about pure water in the past month have been answered very close to the essence."

She was referring to the basic element theory proposed by Rosen.

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

Laertlis asked, "How to celebrate?"

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

How could Rosen not understand what it meant?

Then celebrate it well.

After the celebration, he asked Laertlis: "Are you going back to Hank Island or continuing 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 got on the third version of the electric carriage and returned to the Crescent Castle under the escort of guards such as Alia.

On the way back to the city, he suddenly discovered that there were many tempered clay buildings in Xinyue 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 Xinyue City. Most of the new buildings were made of tempered yellow clay, and the architectural style was simple and practical.

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

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

While he was sighing, the telegraph machine in the car suddenly rang, and the intelligence assistant mage in the front passenger seat quickly translated the code.

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

Rosen's heart moved. He had set up multiple "Detection Guard" seals in the port, and updated them from time to time to ensure 24-hour monitoring of incoming personnel without blind spots.

At this time, he immediately asked Lai Fu to call up the screen and check 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 Sturgeon Mansion. "

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

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

This is inevitable, and he has made full preparations.
