"Phew —"
Xu Yi let out a long sigh, put down the knife in his hand, and wiped the sweat off his face. But he found that his hand felt strange, and when he looked again, his hand was full of oil stains. He was afraid that his face had turned into a big dirty cat.
Xu Yi didn't care about this at all. He laughed, and looked at the strange looking iron lump in front of him with joy.
It was not appropriate to call it a lump of iron. This thing had a square base, and the top was a hollow space. The space was large, and the steel bars were connected together. In the middle, there were three evenly distributed fan blades.
Obviously, this was the fan that he had successfully developed.
This fan that was powered by a Magic Array took Xu Yi half a month to finish.
What he spent the most time on was not the most important power source, but the casting of the fan's outer shape.
After solving the main problem of using magic to replace the motor, Xu Yi found a serious problem. The outer shell of the fan was difficult to imitate from the models of electric fans on Earth, because this world did not have a perfect plastic and alloy manufacturing process.
Helpless, Xu Yi could only use iron as a substitute.
And because this world's casting process was not as fine as Earth's, the final product was a bit strange, and could even be said to be very ugly.
"Well, I can't ask for too much, as long as it can be used." Xu Yi shrugged, comforting himself.
After carefully checking twice, Xu Yi picked up a piece of magic crystal that was only the size of his thumb, and carefully put it into the back of the fan, and then sealed the entrance.
It was just a simple action, but Xu Yi was covered in sweat. After wiping his face, he raised his right hand with a serious look and reached out his index finger. After hesitating a bit, he pressed it down.
"Pa-da —"
With a crisp sound, the fan's switch was pressed down. Xu Yi immediately felt a trace of magic begin to flow inside the fan. After a while, a light green light that represented the activation of the magic circle came out from the fan's gap.
Xu Yi opened his eyes wide and stared nervously at the fan blades.
A moment later, the three fan blades suddenly trembled and began to rotate slowly.
At first, the fan blades spun very slowly, but it didn't take long before they spun faster and faster. Gradually, the three fan blades were completely indistinguishable from each other, almost becoming one.
Following the high-speed rotation of the fan blades, wisps of cool breeze drifted out of the fan and blew onto Xu Yi, who was drenched in sweat, immediately bringing him a refreshing feeling.
Xu Yi silently enjoyed it for a while, then suddenly waved his fist forcefully.
Success!
###
Seeing Xu Yi walk in with the fan, everyone in the research room looked at him curiously.
What's wrong with this guy today?
Not only did he have a silly grin on his face, but he was also holding such a weird-looking iron lump in his arms. What did he want to do?
"Hey, Xu … Xu Yi, what's this?" Rem couldn't hold back his curiosity as he pointed at the fan in Xu Yi's arms.
"This, it's ….." Xu Yi thought about it and found that calling this thing an electric fan wasn't suitable.
"It's a Magic Fan, I made it when I was bored."
"Magic Fan?" The surrounding people were even more confused.
Rem looked at the fan, but he couldn't feel any magic from it, so his heart was filled with curiosity.
"What is this thing used for?"
Xu Yi laughed. He looked around before placing the Magic Fan on the table in front of Rem.
"Isn't it very hot these past few days, so I wanted to make this thing to cool off everyone."
After saying this, Xu Yi reached out to press the switch.
Everyone in the research room was a magician, so naturally they could feel the flow of magic from the Magic Array inside the Magic Fan. But this flow of magic was very weak, so it could be seen that the Magic Array inside was a very low level Magic Array.
Everyone was surprised to find that the three strange leaf like things inside this strange thing began to rotate and they became faster and faster.
"Wa!
There's wind! "
When Xu Yi put down the Magic Fan, he was facing Rem, so naturally he could feel the wind coming from the Magic Fan. He instantly shouted out in surprise.
"So cool!"
"Wind?"
The surrounding people saw Rem's magic robe begin to move like it was being blown by the wind, so they couldn't help coming over.
When they came in front of the Magic Fan, everyone immediately felt the cool breeze.
It was very hot today and everyone was sweating a bit. Now that the wind was blowing, they immediately felt their bodies become cool.
After enjoying it for a bit, everyone immediately asked Xu Yi.
"Hey, Xu Yi, how did this thing move?
Is it because of the Magic Array inside? "
"That can't be right, right?
The Magic Array is fine, but how did the Magic Array make this thing move?
I've never heard of a Magic Array that had this effect. "
"Then it must be something Xu Yi researched himself.
Right, Xu Yi? "
"Researched himself?
Xu Yi, you're actually this proficient in Magic Arrays?
You can actually research a new Magic Array? "
"That's right, Xu Yi, you can actually research Magic Arrays yourself?
Then why is your magic power still so low? "
… …
These people asked for a while, but most of their questions revolved around Xu Yi's magic power. There were only a few people who asked about the theory behind this Magic Fan.
This was in line with the traditions of the Sines. On the magic continent, magicians rarely cared about magic.
Finally it was Wella who had been looking at the Magic Fan in deep thought who asked the question.
"Xu Yi, there should be a Magic Crystal inside, right?
Otherwise, the Magic Array wouldn't be able to last this long. "
"Right."
Xu Yi pressed the switch and stopped the Magic Fan. He opened the back and took out the small Magic Crystal that was much dimmer because of the consumption of magic.
Wella looked at the Magic Crystal that was around the size of a thumb in Xu Yi's hand and her eyes suddenly shrank.
"If I'm not wrong, this Magic Crystal shouldn't even be an Intermediate Grade Magic Crystal, right?"
Xu Yi spread his hand with a bitter smile, "I don't have money to buy High Grade Magic Crystals."
Wella nodded. She took the Magic Crystal from Xu Yi's hand to look at it before pointing at the Magic Fan.
"Xu Yi, can you open this ….. Magic Fan and let me see the Magic Array inside?"
Xu Yi shook his head with a smile, "I can open it, but it's troublesome to reassemble it."
Seeing the disappointed look on Wella's face, Xu Yi then said, "But it's very easy to see the Magic Array. I have the blueprint here, I can show it to you at any time."
"This ….." Wella hesitated a bit before suddenly making a decision. She pointed at the Magic Fan and said, "How about you sell this Magic Fan to me?"
Everyone was stunned.
Rem couldn't help saying, "Wella, what are you buying this for?
If you're interested in the Magic Array inside, didn't Xu Yi say that he could show it to you at any time? "
Wella shook her head, "This isn't the same."
She ignored everyone's surprised gazes after saying this and looked at Xu Yi as she seriously asked, "Give me a price."
Xu Yi saw the serious expression on Wella's face and felt a bit awkward in his heart.
It seemed like this Wella was really obsessed with magic. Seeing this kind of novel thing, she immediately wanted to investigate it.
But when it came to the price … …
If it was just the cost of the materials, the main cost of this Magic Fan was the structure. Including the wooden base, the steel frame, and etc. The total cost was less than thirty silver coins.
Other than that, adding in the cost of labour and the cost of hiring a blacksmith, the total cost didn't exceed one gold coin.
But among these costs, the most important was the research cost.
In order to develop the Magic Fan, Xu Yi had spent half a month on it. He had spent almost all his free time on this and just to develop the Magic Array, he had used over a hundred pieces of paper.
Not to mention changing the entire frame to make it fit perfectly with the Magic Array. This was earth's mechanical engineering knowledge that far surpassed Sines, so the value of this was hard to estimate.
Seeing that Xu Yi was actually hesitating, Rem was instantly unhappy. He said with a frown, "Hey, Xu Yi, this is just an iron frame, how much is it worth?
Since Wella wants to buy it, why don't you sell it to her?
Just give me a price, I'll pay it. "
Wella knit her brows as she looked at Rem, but she didn't say anything.
Although she was very curious about this Magic Fan, she didn't think that this strange looking thing was worth that much money.
Who would have thought that Xu Yi would think for a bit before raising two fingers, "Since we're colleagues, if you really want to buy it, it'll be two gold coins."
This price could be said that Xu Yi had completely given up on the research cost and was treating this Magic Fan as a normal product.
He wasn't worried that Wella would be able to study the mysteries of the Magic Fan after buying it. Perhaps she could easily see through the Magic Array, but she couldn't see through the modern technology behind this normal looking Magic Fan no matter what.
However, this price that Xu Yi felt was very good in his heart made everyone's eyes pop out.
"Two gold coins?" Rem waved his arms exaggeratedly.
Rem waved his hand in an exaggerated manner, "I say, Xu Yi, are you crazy?
This is just a lump of iron!
Although it's not bad that you can think of something like this, how can it be worth two gold coins? "
The surrounding people all agreed. They also felt that Xu Yi's price was too exaggerated.
Although Wella didn't say anything, her deeply knit brows made her thoughts very clear.
Xu Yi gave a sigh, feeling a bit helpless.
The people of this world didn't know anything about modern industry, so naturally they wouldn't understand the value.
From a magician's point of view, the Magic Array inside the Magic Fan indeed wasn't worth two gold coins.
As a high level mechanical engineer from earth, Xu Yi had his own dignity. He definitely wouldn't allow the thing that he worked hard to develop to be sold for such a low price.
So he could only shrug his shoulders, "Since you can't accept this price, then forget it. Anyway, I just felt that the lab was very hot, so I brought it over for everyone to use."
Everyone looked at Xu Yi with strange gazes. This fellow, since he was willing to let everyone use it for free, why didn't he just do a favour and sell it to Wella at a low price?
Wella hesitated a bit. When she wanted to keep persuading Xu Yi, there was a clear voice that came from the lab door.
"Two gold coins, I'll buy it."
