Chapter 3 Magic Fan

"call--"

Xu Yi let out a long sigh, put down the utility knife in his hand, and wiped the sweat off his face, but found that the hand felt very strange. Looking at it again, it turned out that there were all oil stains on his hands. Has become a big cat.

Xu Yi didn't care about it at all, he smiled, and looked at the strange looking iron lump standing in front of him with joy.

It's a bit inappropriate to say that it is an iron lump. This thing has a square base with a hollow space above it. The steel bars with large gaps are connected together, and three evenly distributed fan blades are wrapped in the middle.

Obviously, this is the fan he developed successfully.

It took Xu Yi half a month to develop this fan driven by the magic circle.

Among them, it is not the most important power source that makes him spend the most time, but the casting of the fan.

After solving the main problem of replacing the motor with the magic array, Xu Yi found a serious problem. It is difficult to imitate the fan's casing according to the models of those electric fans on the earth, because there are no perfect plastics and alloys in this world. Craftsmanship.

In desperation, Xu Yi could only use iron instead.

And because the casting process in this world is far less refined than on the earth, the final table fan looks a little weird, and it can even be said to be ugly.

"Forget it, the requirements can't be too high, as long as it can be used." Xu Yi shrugged and comforted himself.

After doing two more careful inspections, Xu Yi picked up a piece of magic crystal that was only the size of his thumb with some variegated colors, and carefully put it into the insertion port behind the fan, and then sealed the entrance.

It was just a simple action, but Xu Yi was sweating all over, and after wiping his face again, he raised his right hand solemnly, stretched out his index finger, hesitated for a moment, and then pressed it down.

"pat-"

With a crisp sound, the switch of the fan was pressed down, and Xu Yi immediately felt that a trace of magic power began to flow inside the fan. After a while, the light blue light representing the activation of the magic circle came out from the gap of the fan.

Xu Yi widened his eyes and stared nervously at the fan blade.

After a while, the three fan blades trembled suddenly, and started to rotate slowly at random.

At first, the speed of the fan blades was very slow, but it didn't take long for them to rotate faster and faster. Gradually, the three fan blades were completely indistinguishable from each other, and almost became one.

With the high-speed rotation of the fan blades, wisps of fresh wind wafted out of the fan, blowing onto Xu Yi, who was covered in sweat, instantly bringing him a burst of refreshment.

Xu Yi enjoyed it silently for a while, then suddenly threw his fist hard.

It worked!

###

Seeing Xu Yi walking in with a fan in his arms, everyone in the research room cast curious glances at him.

What's up with this guy today? With a smirk on his face, he still holds such a weird looking iron lump in his arms, what does he want to do?

"Hey, Xu...Xu Yi, what is this?" Rem couldn't hold back his curiosity and asked, pointing to the fan in Xu Yi's arms.

"This, it's..." Xu Yi thought about it for a while, and found that it seemed inappropriate to call this an electric fan. "It's a magic fan, I made it out when I was idle."

"Magic fan?" The people around were even more baffled.

Rem looked at the fan, but couldn't feel any magic power from it, and was surprised.

"What is this thing for?"

Xu Yi smiled, looked left and right, and placed the magic fan on the table in front of Rem.

"Isn't it very hot these days, I just want to make this thing to let everyone cool down."

After speaking, Xu Yi reached out and pressed the switch.

Everyone in the research room is a magician. Naturally, they felt the flow of magic power when the magic circle inside the magic fan was activated for the first time, but the flow of magic power was extremely weak. It can be seen that the magic circle in it must also be a very low-level magic circle.

Immediately, everyone was surprised to find that the three leaf-like things in this strange thing actually began to rotate, and the speed was getting faster and faster.

"Wow! It's windy!" Xu Yi was facing Rem when he put down the fan just now. He naturally felt the wind blowing from the fan for the first time, and suddenly shouted in surprise. "It's so cool!"

"Wind?" The people around saw that the magic robe on Rem's body began to swing, as if being blown by the wind, so they involuntarily came over.

As soon as they came to the front of the fan, everyone immediately felt the cool breeze.

It was still very hot today, and everyone was sweating a little bit. Now that the wind was blowing, they immediately felt cool all over.

After enjoying it for a while, everyone immediately asked Xu Yi.

"Hey, Xu Yi, how did this thing move? Is it because of the magic circle inside?"

"Isn't it? The magic circle is easy to say, but how does the magic circle make this thing spin? I haven't heard of any magic circle that has this effect."

"That must have been researched by Xu Yi himself. Right, Xu Yi?"

"Research on your own? Xu Yi, are you so proficient in magic circles? You can actually research new magic circles by yourself?"

"Yes, Xu Yi, you can actually study the magic circle yourself? Then why is your magic power so low?"

...

These people asked for a long time, but most of the questions revolved around Xu Yi's magical power, but very few people asked about the principle of this magical fan.

This is also in line with the tradition of Sainz Continent. In this magical continent, magic applications are rarely concerned by magicians.

In the end, Wella, who had been looking at the magic fan in deep thought, asked.

"Xu Yi, there should be magic crystals in it, right? Otherwise, the magic circle couldn't last for so long."

"Yes." Xu Yi pressed the switch, stopped the rotation of the fan, opened the insertion port at the back, and took out the small piece of magic crystal that was obviously dimmed due to the consumption of magic power.

Wella looked at the magic crystal on Xu Yi's hand that was about the size of his thumb, and her eyes shrank suddenly.

"If I read it right, this magic crystal should not even reach the intermediate level, right?"

Xu Yi spread out his hands with a wry smile: "I don't have the money to buy high-grade magic crystals."

Wella nodded, took the magic crystal from Xu Yi's hand and looked at it, then pointed to the magic fan.

"Xu Yi, can you take apart this... magic fan, and let me see the magic circle inside?"

Xu Yi smiled and shook his head: "It can be disassembled, but it is more troublesome to re-install." Seeing the disappointed expression on Wella's face, Xu Yi said again: "But it's easy to see the magic circle, I have the drawings here, you can always do it at any time. show you."

"This..." Wella hesitated for a while, and suddenly seemed to have made up her mind. She pointed at the magic fan and said, "How about selling this magic fan to me?"

Everyone around was stunned.

Rem couldn't help but said: "Wella, what are you buying this for? If you are interested in the magic circle inside, didn't Xu Yi just say that he can show it to you anytime."

Wella shook her head: "It's not the same." After that, she ignored everyone's surprised eyes, stared at Xu Yi, and asked earnestly, "Let's make a price."

Xu Yi looked at the serious expression on Wella's face and felt a little troubled in her heart.

It seems that this Wella is really obsessed with magic, just seeing such a novel thing, she has to immediately find out.

But speaking of pricing...

If you only count the cost of materials, the main cost of this magic fan is concentrated on the structure, including the wooden base, frame steel bars, etc. The total cost is less than thirty silver coins.

In addition to the labor cost, including the cost of hiring a blacksmith and others, the total cost will not exceed one gold coin.

But the most important of these costs is actually the cost of research.

In order to develop a successful magic fan, Xu Yi spent more than half a month, of which he spends almost every day in his spare time, and it took him more than a hundred to develop a completely suitable magic circle. sheet of paper.

Not to mention the transformation of the entire frame structure so that it can be perfectly assembled with the magic circle, which is a fusion of mechanical craftsmanship knowledge far beyond the continent of Sainz on the earth, and the value contained in it is inestimable.

Seeing that Xu Yi hesitated, Rem suddenly became unhappy and frowned: "Hey, Xu Yi, this is just an iron frame, and how much is it worth? Since Wella wants to buy it, you can sell it to her. Right? Just ask for a price, and I'll go out."

Wella frowned and glanced at Rem, but said nothing.

Although she was very curious about this magic fan, she also didn't think that this grotesque thing was worth a lot of money.

Who knew that Xu Yi thought about it for a while, and then gestured with two fingers: "For the sake of my colleagues, if you really want to buy it, two gold coins."

This price can be said that Xu Yi has completely abandoned the research cost, but automatically regards this magic fan as a general commodity.

He is not worried that Wella will be able to study the mystery immediately after buying the magic fan. Maybe she can easily see through the magic circle, but the modern mechanical craftsmanship contained in this seemingly inconspicuous magic fan, She couldn't see through it anyway.

However, this price, which Xu Yi thought was very conscientious, made everyone's eyes widen.

"Two gold coins?" Rem waved his arms exaggeratedly. "I said Xu Yi, are you crazy? It's just a lump of iron! Although you can come up with this very good thing, it's not worth two gold coins, right?"

Everyone around agreed, and they also felt that Xu Yi's price was too exaggerated.

Although Wella didn't speak, her deeply wrinkled brows made her mind very clear.

Xu Yi sighed, a little helpless.

People in this world know nothing about modern industry and naturally do not understand the value of it.

Purely from a magician's point of view, the magic circle in this magic fan is indeed not worth two gold coins.

As a senior mechanical engineer on earth, Xu Yi has his own dignity, and he will never allow the things he has worked hard to research to be sold at such a low price.

So he could only shrug: "If you don't accept the price, then forget it. Anyway, I just thought it was very hot in the research room, so I brought it here for everyone to use."

The eyes of everyone looking at Xu Yi are a bit weird. Since this guy can be used by everyone for free, why not just be a good friend and sell it to Wella at a low price?

Wella hesitated for a while, and just as she was about to continue persuading Xu Yi, a beautiful voice suddenly sounded at the door of the research room.

"Two gold coins, I bought them."
