"call--"

Xu Yi let out a long breath, put down the tool knife in his hand, wiped the sweat on his face, but found that the touch was very strange. When he looked again, it turned out that his hands were covered with oil stains. With this wipe, his whole face might have turned into a big cat.

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

It is somewhat unsuitable to say that it is an iron lump. This thing has a square base, and above it is a space separation. Steel strips with large gaps are connected together, and three evenly distributed fan blades are wrapped in the middle.

Obviously, this is the fan he has successfully developed.

This fan powered by the magic array took six months to develop.

The one that took him the most time was not the most important power source, but the appearance casting of the fan.

After solving the main problem of replacing the motor with magic arrays, Xu Yi discovered a serious problem. The shell of this fan is difficult to imitate according to the models of those electric fans on the earth, because there is no perfect plastic and alloy making technology in the world.

In desperation, Xu Yi could only use iron tools instead.

And because the casting process in this world is far less refined than that on earth, the fan I made in the end looks a bit weird, and it can even be said to be very ugly.

"Well, the requirements cannot be too high, just use them." Xu Yi shrugged and comforted himself.

After two more detailed inspections, Xu Yi picked up a magic crystal with a few colors that were only the size of his thumb, carefully placed it into the embedding port behind the fan, and then closed the entrance.

Just a simple move, Xu Yi was sweating all over. After wiping his face again, he raised his right hand with a serious expression, stretched out his index finger, hesitated for a moment, and then pressed it down.

"Pu"

With a crisp sound, the fan switch was pressed down, and Xu Yi immediately felt a trace of magic power inside the fan begin to flow. After a while, a light green light that represents the activation of the magic circle emerged from the gap of the fan.

Xu Yi widened his eyes and stared at Fanye nervously.

After a while, the three fan blades suddenly shook and began to rotate slowly.

At first, the fan blades rotated very slowly, but it didn't take long, and the rotation speed became faster and faster. Gradually, the three fan blades could not be separated from each other at all, and almost became one piece.

As the fan blades rotated at high speed, a breeze floated out of the fan and was blowing on Xu Yi, who was sweating profusely, and immediately brought him a refreshing moment.

Xu Yi enjoyed it silently for a while, and suddenly waved his fist hard.

Success!

###

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

What happened to this guy today? He didn't say anything, but he was holding such a weird iron lump in his arms. What did he want to do?

"Hey, Xu... Xu Yi, what is this?" Rem couldn't help but curiosity in his heart and asked at the fan in Xu Yi's arms.

"This is, it's..." Xu Yi thought about it and found that it didn't seem suitable to call this electric fan. "It's a magic fan, I made it out while I'm idle."

"Magic Fan?" Everyone around was even more puzzled.

Rem looked at the fan, but couldn't feel any magic in it, and he was very surprised.

"What is this thing for?"

Xu Yi smiled, looked around 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 cool everyone down."

After saying that, Xu Yi reached out and pressed the switch.

Everyone in the research room was a magician, so naturally felt the magic flow when the magic circle inside the magic fan was activated at the first time, but the magic circle was extremely weak, which shows that the magic circles in it must be very low-level magic circles.

Then everyone was surprised to find that three even stranger leaves-like things inside this weird thing actually started to rotate, and the speed was getting faster and faster.

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

"Wind?" Everyone around saw that the magic robe on Rem began to swing, as if it was blown by the wind, so they couldn't help but come over.

As soon as they arrived at the front of the fan, everyone immediately felt the cool breeze.

It was still very hot today, and everyone was sweating a little more or less. Now when the wind blew, I immediately felt cool all over.

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

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

"No, right? The magic array is okay, but how did the magic array turn this thing? I haven't heard of any magic array having this effect."

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

"Study it yourself? Are you so proficient in magic circles? Can you actually develop a new magic circle by yourself?"

"Yes, Xu Yi, you can actually study the magic array by yourself? Then why is your magical strength still so low?"

...

After asking these people for a long time, most of the questions were around Xu Yi's magical strength. Few people asked about the principle of this magic fan.

This is also in line with the tradition of the Continent of Sainz, where magical applications are rarely cared for by magicians.

In the end, Wina, who had been looking at the magic fan, asked.

"Xu Yi, there should be magic crystals here? Otherwise, the magic array would not last for so long."

"Yes." Xu Yi pressed the switch, stopped the rotation of the fan, opened the embedding port behind, and took out the small piece of magic crystal that was significantly dimmed due to the consumption of magic.

Wina looked at the magic crystal on Xu Yi's hand, which was about the same size as his thumb, and her eyes shrank suddenly.

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

Xu Yi smiled bitterly and spread his hands: "I don't have the money to buy high-level magic crystals."

Wina nodded, took the magic crystal from Xu Yi and looked at it, then pointed at the magic fan.

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

Xu Yi smiled and shook his head: "It's OK to disassemble it, but it's more troublesome to reinstall it." Seeing the disappointed expression on Wina's face, Xu Yi said again: "But it's easy to see the magic circle. I have drawings here and I can show you anytime."

"This..." Wina hesitated for a moment, and suddenly pointed to the magic fan as if she had made up some decision and said, "How about selling this magic fan to me?"

Everyone around was stunned.

Rem couldn't help saying, "Wina, what are you buying this for? If you are interested in the magic circle inside, didn't Xu Yi just say that you can show it to you at any time."

Weina shook her head: "This is different." After saying that, she ignored everyone's surprise gaze, stared at Xu Yi, and asked seriously: "Let's make a price."

Xu Yi looked at the serious expression on Weina's face and felt a little distressed.

It seems that Wina is really obsessed with magic. She just needs to find out what's going on when she sees such a novel thing.

But when it comes to pricing...

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

In addition, including the labor cost, including the cost of asking the forge and others, the total cost will not exceed one gold coin.

But among these costs, the most important thing is actually the research cost.

Xu Yi spent more than half a month to develop the magic fan, and almost every day spent his spare time. He used more than a hundred pieces of paper just to develop a perfectly suitable magic array.

Not to mention that the entire framework structure can be transformed to perfectly integrate with the magic circle, it is a combination of mechanical technology knowledge on the earth far beyond the Synes continent, and the value contained in it is incalculable.

Seeing that Xu Yi was hesitating, Rem was immediately displeased and frowned and said, "Hey, Xu Yi, this is just an iron rack, how much money is worth? Since Vina wants to buy it, you can sell it to her? Just offer it at any price, I'll pay it."

Wina frowned and glanced at Rem, but said nothing more.

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

Who knew that Xu Yi thought for a while, stretched out his two fingers and gestured: "For the sake of our colleagues, if you really want to buy it, you can just buy two gold coins."

This pricing can be said that Xu Yi has completely abandoned the research cost and has automatically regarded this magic fan as a general product.

He was not worried that Vina could immediately study the secrets after buying the magic fan. Perhaps she could easily see through the magic array, but she could not see through the modern mechanical craftsmanship contained in this inconspicuous magic fan.

However, this price, which Xu Yi felt very conscientious in his heart, made everyone's eyes widen.

"Two gold coins?" Rem waved his arms exaggeratedly. "I said Xu Yi, are you crazy? This is just an iron lump! Although it is very good to think of this thing, it is not worth two gold coins, right?"

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

Although Wina didn't speak, her deep frown made her mind very clearly.

Xu Yi sighed, feeling helpless.

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

From the perspective of a magician, the magic array inside this magic fan is indeed not worth two gold coins.

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

So he could only shruggle: "Since I don't accept this price, then forget it. Anyway, I just think the laboratory is very hot, so I took it over and let everyone use it."

Everyone looked at Xu Yi with a strange look. Since this guy can be used free of charge, why not just make a favor and sell it to Vina at a low price?

Weina hesitated for a moment, and was about to continue persuading Xu Yi, when a clear voice suddenly sounded from the door of the laboratory.
