Hearing Vivian's words, Yanis just glanced at her with some confusion and didn't say anything, but Xu Yi asked curiously with a hint of expectation: "Why not?" Vivian, do you see what's wrong?"

Xu Yi did have great expectations for Vivian, because since he accidentally discovered Vivian's talent in the design of mechanical products last time, he simply sent Vivian to Baron Rictor's Academy of Magic to study painting, just to tap her talent in this area.

Now seeing that she actually disagreed with such a beautiful magic lamp drawn by Yanis, Xu Yi was not only not the slightest surprised, but very excited.

"This ......" Vivien looked at Yanis, and saw that this sister with a pair of long ears and a legendary elf did not show any dissatisfied expression, so she hesitated to light the magic lamp on the painting, pointed to the exquisite pedestal and said: "If it is a pedestal like this, there is no way to completely inlay the magic array." ”

Xu Yi looked at the place where Vivien was pointing, thought for a moment, and realized that Vivien was not wrong at all.

The overall structure of this magic lamp was conceived by Evita herself, because she did not learn the relevant shape design, but only designed it according to her own requirements, so many places are a little ill-considered, or there is no relevant understanding at all......

The current appearance of this magic lamp is obviously the appearance determined by Evita after many experiments, and it does not take into account too much room for expansion of the appearance, and when Yanis changes it like this, there is an immediate problem.

One of the most important problems is that the design of this base is just right to be inlaid with magic arrays. But with Yanis changing it like this, the space left on the base is much smaller. There's no way to put the same magic array on it.

In other words, such a form factor design. It's a complete failure.

Xu Yi looked at Vivian and couldn't help but nod appreciatively.

She can actually see at a glance the most important and critical issue in this appearance, which shows that she really has talent in this area.

"Very well, Vivien, you're right. Xu also praised. "So according to your thoughts, how should this magic lamp be changed?"

"I think it's better to change it like this......"

Perhaps because Xu Yi's encouragement had given her courage, Vivien took the brush and sketchpad directly from Annis and put together a new pattern of a magic lamp on another piece of paper.

I have to admit that the elves do have a unique talent in art. Although Vivien is also a bit talented in painting, and she also went to study at Baron Rictor's School of Magic for a while, the picture she draws now is also extremely vivid and looks lifelike, but it is slightly inferior in terms of giving people an impression.

However, unlike Kianis who simply gave an exterior drawing, Vivian not only drew the appearance, but also gave some plane design drawings of the internal structure, which looked more intuitive.

And this comes from Xu Yi's usual guidance to Vivian.

Wait for Vivien to finish painting. Xu Yi immediately praised without hesitation: "Okay! Vivian, you have painted amazingly!"

Vivian's design drawing fully takes into account the overall design of the magic lamp, not only leaving enough space for the magic array. There is also a partial margin of change.

In addition, from the design of the glass cover outside, Vivian also took into account the problem of light gathering and dispersion. She cleverly changed the top part of the glass cover to a curved, opaque mirror.

Although the specific effect cannot be seen through the design drawing, this design shows that she has taken into account the problem of the dispersion of light sources. And Xu Yi didn't teach her this at all, and Evita and Akali didn't think about it. It can be seen that this is completely her own idea.

Vivian, who was praised by Xu Yi, couldn't help but have a smug expression on her face, and when she looked at Yanis, she raised her head slightly.

Annis didn't notice Vivian's small movements, but looked carefully at Vivian's drawings for a while, and shook her head: "No, this is still not beautiful enough. ”

Xu Yi's heart moved, and he gave her the design drawing.

"Then Yanis, you try to change it according to the standard of what you think is good. ”

"Is that okay?" Annis looked at Vivien.

Vivien hesitated, and although she was a little reluctant in her heart, she nodded obediently.

So Yanis quickly completed a new drawing.

This time, she even made some corrections to the interior floor plan that Vivien had given.

The revised design really looks much more beautiful and refined, and even Vivien, who was a little unconvinced, had to admit it.

But soon Vivien noticed a few more problems, pointed them out unceremoniously, and redrew a new design.

Annis once again gave her opinion on the appearance and drew a new picture.

Vivien also figured out a few more minor problems and drew a new design.

Annis ......

......

The next morning, Xu Yi woke up on time.

As soon as she stepped out of the room, she saw drawings scattered all over the living room, and Yanis and Vivien were both asleep on the table in the living room.

Looking at the exhaustion on their sleeping countenances, I am afraid that they fell asleep very late.

Xu Yi couldn't help but shake his head, seeing that Yanis and Vivian were actually competing last night, he wisely chose to retreat and crawl to sleep first.

And looking at the current picture, I wonder if they just tossed around all night.

Xu Yi looked at Yanis's delicate and beautiful face and couldn't help laughing.

Vivien is no more, Yanis claims to be seventy-four years old, but she has the same temper, and is embarrassed not to let herself call her a little girl.

Xu Yi carefully picked up the drawings on the table and looked at them, and immediately couldn't help but sigh in his heart.

Judging from the situation on these drawings, the two of them have gradually reached a unity in the back, and finally the magic lamps on these drawings are not only beautiful. The overall structure is almost perfect, and even Xu Yi can't see any problems.

Such a magic lamp shape design. It can already be regarded as a success, or it can be said that the shape design is extremely good.

Xu Yi took out one casually. I thought that if I made the magic lamp on it, I was afraid that it would immediately arouse the interest of most people.

If nothing else, just for this excellent appearance, it is worth spending money on.

Looking at Yanis and Vivien, who were still asleep, Xu Yi smiled slightly.

This is really a nowhere to find the iron shoes, and it takes no effort to get it.

When Xu Yi entered the production workshop of the household magic machine, he found that the magicians recruited yesterday had already started their work at this time.

This is the first time that a magician is working on drawing a magic array in the workshop in the morning, and Xu Yi is still a little unaccustomed to it after seeing it.

The students from Baron Rickato's Academy of Magic and Magic, who had been hired before, only came in the afternoon when there were no classes, or when they were on vacation. Of course, the working hours are far inferior to those of these full-time magicians.

Moreover, Xu Yi watched from the side for a while, and found that these magicians really had a deeper understanding of the magic array than the students.

Originally, it took about half an hour for the students to complete the small frost and cold circles and small flame circles on the cold and heating magic air conditioner, and although the skills of these magicians were high and low, each of them was able to shorten this time to about twenty minutes.

This is because they are not very skilled on the first day of work, and if they are skilled enough, they can compress the time to ten minutes.

More efficient, longer working hours, so in contrast. Hiring these magicians can be much more effective than hiring students.

In this case, of course, the happiest is Heinze.

In the past, the work progress of the household magic machinery production workshop had been limited by the completion efficiency of the magic array, and because the people who completed this work were all students of Baron Ricto's magic academy, there was no way to ask them to improve their efficiency regardless of their studies.

Even if Xu has recruited many times. There are still not enough students who will come to work here, and the production capacity of the production workshop of the director's household magic machinery has not been able to keep up, so Heinze always sighs about it.

And the bigger question is. As Xu Yi continued to let the magic machine tool workshop develop new magic machine tools, and improve the previous magic machine tools. As a result, the production efficiency of ordinary workers in the production workshop of household magic machinery has gradually increased, and has even reached two or even three times that of the beginning.

And correspondingly. The efficiency of the students' drawing of magic arrays is limited by the fact that the students' magic strength can hardly be improved, so in this way, a phenomenon that makes Heinze very helpless gradually arises.

That is, workers often have already produced all the external parts of products such as magic rice cookers and magic air conditioners, but they still have to wait for the students to draw the magic array before they can complete the assembly, which has a great impact on production efficiency.

Now these magicians are hired, although there are only nine people, but in terms of work efficiency, they are worth thirty students, and they have solved Heinze's urgent need at once, so that the entire workshop can run more smoothly, and the work efficiency has been greatly improved, so it is no wonder that when he saw Xu Yi, his face was smiling.

"Haha, Xu Yi, I don't think you need to recruit more magicians at all. As long as these few people become proficient, we may not even be able to hire those students. ”

Xu Yi glanced at Heinze, who was a little carried away, and thought that this guy's petty family spirit could not be changed in his life.

Not to mention that these nine magicians may resign and leave at any time, even for the future development of the Chamber of Commerce, it is still necessary to recruit a large number of magicians.

In addition to completing the simple work of drawing magic circles, the more important work is the research work on the magic circles used in magic machines.

Not to mention anything else, just the changes made by Grand Magician Camilla and Steele to the two magic arrays in the magic air conditioner last time made the entire appearance of the cooling and heating magic air conditioner reduced by nearly half, and the cost of the magic air conditioner was reduced by nearly one-third at once.

Without this change, Xu Yi estimated that the profit of the Magic Air Conditioner would be between thirteen and fifteen gold coins per unit, but with this change, this profit skyrocketed to nearly twenty gold coins1

With the popularity of the magic air conditioner among the aristocracy and wealthy homes in Bangta City and several nearby cities, the Xinfei Chamber of Commerce has received orders for more than 1,000 units so far.

To sum up, just relying on the commodity of magic air conditioning, the Xinfei Chamber of Commerce can make a huge profit of nearly 20,000 gold coins this winter!

And a third of this huge profit comes from this small change.

This is the power of scientific research! (To be continued......
