It has been nearly two months since he came to Camilla's Magic Tower, but this is the first time Xu Yi has entered the top floor of the Magic Tower.

As soon as he stepped into the exclusive area of Grand Magician Camilla, a refreshing coolness immediately hit the shop, making Xu Yi shiver and almost sneeze.

"It's nice to have a large frost circle. Xu Yi rubbed his nose and smiled at Steele, who was leading the way in front.

"What's the matter?" Steele looked back at Xu Yi, his eyes full of curiosity.

Some time ago, Xu Yi researched that magic fan to surprise her, but she didn't expect that now her grandfather would suddenly summon him. Coupled with the impression left on her on Xu Yilai's first day, Steele was very interested in Xu Yi.

"Of course I envy it. Xu Yi replied as a matter of course. "The seniors of the research room have said countless times in private, if they can also arrange a large frost circle in the research room, everyone's work efficiency can be increased by at least several times. ”

Steele grinned, shook his hand, and said, "That's not going to work. Grandpa was a notoriously poor man, but he couldn't afford to put a large frost circle in every research room. Even the circle he has here is only activated on the hottest days, and it's usually just a decoration. ”

Xu Yi knew a little about this, but he was still very curious.

"Miss Steele, isn't that right? His Excellency Camilla is also a three-star great magician, not to mention anything else, just the kingdom gives him a lot of fixed investment every year, why is he poor?"

"Because there's more to spend money. Steele shrugged, his expression helpless. "You only know that grandpa is a great magician and enjoys the special salary of the kingdom, but you don't know that studying magic, especially high-level magic like grandpa, costs extremely high, he spends more than half of his annual purchase of magic materials for research, and the rest has to maintain the daily expenses of the magic tower, which is actually very tight. ”

"That's right...... But I've heard that the other great magicians are very rich......"

"Are you trying to say that grandpa doesn't have the ability to make money?" Steele glanced at Xu Yi. "Sue you, you can't say this in front of your grandfather, otherwise he will be very angry. ”

"No, no, no, of course I wouldn't think so. I've just heard that Lord Camilla has always been very opposed to magicians focusing on making money......"

"No way, grandpa is so stubborn. Steele sighed. "I've tried to persuade him several times, but he always says that magicians should focus their energies on studying magic, and that he is completely ashamed of his name as a magician when he thinks about making money. ”

Xu Yi nodded and said no more.

Grand Magician Camilla's attitude reminded him of the professors and scholars on Earth who focused on research, and they were also dismissive of business, believing that academic research tainted with the smell of copper would deteriorate as a result.

Xu Yi does not appreciate this attitude, although too strong commercial atmosphere is bound to have a great impact on academic research, but with commercial investment, after the increase of research funding, the research environment and conditions can be greatly improved, and the progress and efficiency of academic research will be greatly improved.

There is no shortage of examples on the planet where academic research and business are perfectly combined, and the two promote each other, and the effect is better than just burying one's head in research.

Moreover, the mechanical engineering industry where Xu Yi works is originally a science that is very close to practical application, if it cannot reflect the commercial value in practical application, it will be a failure.

"It's here. Steele pushed the door open and gestured to Xu Yi. "Go in, grandpa is waiting. ”

Xu Yi tidied up the clothes on his body and walked in with his head held high.

Grand Magician Camilla's private research room occupies the entire top floor of the magic tower, and the area is naturally extremely vast, which is as large as four or five research rooms where Xu Yi is located.

The top of the research room is very high, the top of which is more than five meters above the ground, and when viewed from left to right, the place is almost the size of a slightly smaller basketball hall.

In the middle of the entire space is a large table, behind which is an old man wearing a dark blue ** robe and dark brown hair, burying his head in magic research.

This should be the Grand Magician Camilla.

Hearing the sound of someone coming in, Grand Magician Camilla raised his head, and when he saw Xu Yi, he looked at him slightly, nodded, and continued to study with his head down.

Xu Yi was not surprised by this, he had long heard that Grand Magician Camilla was extremely obsessed with the study of magic, and he must be immersed in a certain question now, and he was unwilling to interrupt.

Taking advantage of this time, Xu Yi carefully looked at the environment in the research room.

The situation in the research room was much more neat than he had expected, all kinds of strange magical materials were arranged against the wall, but the table where the Grand Magician Camilla was located was more cluttered.

Various strange traces can be seen on the ground and on the walls, which should have been left by Grand Magician Camilla when he was doing magic practice.

Many of the traces are so profound that you can see that the situation must have been very dangerous.

Xu Yi's gaze suddenly stopped somewhere in the corner of the wall, where there was a ball of rotten iron, but Xu Yi easily saw from the rotten iron that this piece of rotten iron should be the first magic fan he made that Steele bought before.

Judging from the tattered appearance of this magic fan, it should have been vandalized.

As for the saboteurs......

Xu Yi's gaze turned back to Grand Magician Camilla, and there was something strange in his heart.

"Could it be that Grand Magician Camilla is also interested in this magic fan, but the magic level in this thing is so low, it shouldn't be taken seriously by him, right?"

It didn't take long for Grand Magician Camilla to seem to finish her research, stretch out, and straighten up.

After seeing Xu Yi, Camilla Grand Magician was slightly stunned, as if he had forgotten Xu Yi at all.

After a slight pause, he nodded to Xu Yi: "You are Xu Yi, right?"

Xu Yi hurriedly saluted respectfully: "It's me, Your Excellency the Honorable Great Magician." ”

Grand Magician Camilla waved his hand: "Don't be so nervous, I asked Steele to come to you because I wanted to ask you a few questions." ”

"Please feel free to ask, as long as I know, I will be happy to answer for you. ”

"Good. Grand Magician Camilla looked left and right, came to the corner of the wall and brought over the rotten iron that Xu Yi had just seen. "Listen to Steele, you made this thing?"

"This ......" Xu Yi looked at the magic fan who could barely see its true face, and replied with some embarrassment, "When it was handed over to Miss Steele, it was not like this. ”

"Don't blame Steele, I wanted to do some research, so I made it like this. Grand Magician Camilla casually tossed the magic fan aside, flipped through the table for a while, and pulled out a drawing. "Well, I'm looking for you, mainly because I'm interested in the magic array you engraved on this magic fan, there are some things I don't understand, I hope you can answer for me. ”

Xu Yi was suddenly in awe of Camilla's Grand Magician, with his status as a three-star Grand Magician, he would admit that there were some things he didn't understand in front of him, who didn't even pass the Magician's Guild qualification assessment, which shows that he is very serious about magic.

"Your Excellency Camilla, you are too polite, I think there must be nothing incomprehensible about this magic array for a great magician like you, what you can't understand, probably has nothing to do with magic, right?"

Grand Magician Camilla pondered for a moment and shook his head: "It's okay to say it's irrelevant, but it can't be said to be completely unrelated." Come, come and see, here ......" Grand Magician Camilla reached out and tapped a certain point on the magic array. "I can understand that your changes here will make the whirlwind effect of the magic array less effective, but I don't understand why you're doing it. Don't you want to make the magic array more powerful?"

Xu Yi poked his head and glanced at it, and immediately replied with a smile: "What you said is not bad at all, this change will indeed reduce the power of the magic array, but Your Excellency, this magic array is mainly to provide power to the magic fan, and it does not need to provide such a powerful effect at all." ”

Grand Magician Camilla shook his head: "That's not right, I've tried your magic fan, although the wind blowing out is not small, but have you ever thought that maybe sometimes you need a bigger wind? For example, you see, my room is so big, if you only put a magic fan, it can only blow a small area, which can't meet my requirements at all." ”

Xu Yi smiled bitterly and spread out his hand: "Your Excellency Camilla, I actually considered this problem when designing the magic fan, but due to the material of the magic fan, the fan blades can only withstand such a high speed for the time being. If you increase the power of the magic array, the speed of the fan blades can of course be increased, but I'm afraid that the magic fan itself will not be able to withstand it, and it won't take long before it will be damaged. ”

"That's right......" Grand Magician Camilla suddenly remembered the first time he injected magic into the magic fan, when the blades of the fan rotated strongly, but it didn't take long to be unbearable, so that the entire magic fan turned directly into a mass of scrap metal, so Steele complained about him for a long time.

"Well, that aside, what's going on here?"

"Oh, here, this is to ensure that the power output of the entire magic array is maintained within a small fluctuation range, so as to ensure that the wind blowing from the magic fan will not be particularly unstable. ”

"And what about here?"

"This has to be seen in conjunction with the overall design of the magic fan. You see, this is the central axis connection diagram of the magic array and the magic fan, if it weren't designed like this, the things output by the magic array would be greatly affected, and the magic crystals would be wasted. ”

"It's good, and here'......"
