Xu Yi almost choked to death on a bite of food.
"Cough cough cough... cough... Steele, what did you say?"
"Go to your house." Steele was a little confused, but seeing the weird expression on Xu Yi's face, a thought came to his mind and he instantly understood what he meant. His face suddenly turned red, and he couldn't help but punched Xu Yi with his fist. . "what are you thinking!"
Xu Yi quickly waved his hand and said, "Okay, okay, I understand what you mean. You want to go to my house to see the piano model, right? But I don't understand. Why are you so anxious to see it?"
Steele stopped his movements, hesitated for a moment, and asked with some uncertainty: "Xu Yi, which... can you sell me your piano model?"
"Sell it to you?" Xu Yi glanced at Steele in confusion. "What do you want that for?"
"I'm useful," Steele replied vaguely.
Xu Yi didn't think much and shook his head: "I'm afraid not. That thing is also very important to me. I'm afraid I can't sell it to you."
This is not Xu Yi's purposeful refusal. This piano model was made in his spare time when he was studying at Suncor College. It is also his first magical industrial product in this world. It is very commemorative and he is not willing to give it away casually. other people.
"That's it..." Steele was slightly disappointed, and then asked: "Then... can you teach me how to make it? Well, actually I wanted you to teach me how to make it. After all, it's better to make it with your own hands than to make it with your own hands. Things bought from other people are much more valuable.”
Xu Yi looked at Steele strangely: "Steele, let me ask more, do you want to give this thing to someone else?"
"Yeah, I need to give someone a birthday gift now. The piano model I saw last time was very unique and novel. I think it would be a good birthday gift. How about it? Can you teach me how to do it well? I promise not to do it. I’ve treated you badly, as long as you help me this time, I will let grandpa treat you well in the future.”
Xu Yi touched his chin, thinking that even if he didn't take this opportunity to further build a good relationship with the great magician Camilla, just for the sake of Steele, a little beauty, he should do this favor for her. .
"By the way, let me ask again, is the person you want to give a gift to a man?"
Steele's pretty face turned red, and she said coquettishly: "I want you to take care of it!"
Xu Yi laughed, thinking that he was right.
But Steele is nineteen years old, at the prime of his life, so it's not surprising that he likes a little boy.
"Okay, it's okay to teach you how to make it, but there's no need to go to my house. It's already very late now, and it might be inconvenient for a little girl like you to come to my house. Starting tomorrow, you will come to the laboratory to see me after get off work every day. I’ll teach you right there.”
Steele looked at Xu Yi up and down in surprise: "Xu Yi, I don't see that you are still such a decent person."
"Ahem... Do I look like an dishonest person?" Xu Yi glared at Steele and asked angrily: "By the way, when do you need a gift? I can arrange the progress of teaching you. ”
"There's still half a month left, should it be fine?"
"Well, that's enough time. The technical content of that piano model is actually not high, it just needs some fine work."
After the two made an appointment, Xu Yi said goodbye and left, but instead of going home directly as usual, he came to the medical center first.
The little slave, whose whole body was covered with gauze and wrapped almost as much as a mummy, had woken up from a coma. He was lying on the hospital bed in the hospital, staring at the ceiling with a dazed look on his face. A hint of fear.
He only reacted when he heard the conversation between Xu Yi and the doctor. He turned his head and stared at Xu Yi, with strong curiosity in his eyes.
"How do you feel?" Seeing that the little slave was looking over, Xu Yi stopped talking to the doctor and asked him warmly.
The little slave seemed uncomfortable talking to outsiders. He hesitated for a while before slowly nodding.
Xu Yi smiled and did not rush to force him. He asked the doctor a few more questions. After confirming that his body was fine, he explained to the little slave: "It's okay. Your injuries are not fully healed yet." , just rest here for a few more days and I will pick you up when you are completely healed."
Xu Yigang was about to turn around and leave, but suddenly felt the hem of his clothes tightening. He turned around in shock and found that the little slave had reached out his hand at some point and grabbed the hem of his clothes tightly.
Xu Yi looked at the nervous and frightened little slave and immediately understood what he meant.
"What? Do you need someone to accompany you? I'm afraid this won't work. I'm very busy with work, so I'm afraid I won't have time to spend more time with you here. Don't worry, since I've bought you, I won't leave you behind. You can rest assured. Stay here, the doctor said you will be discharged from the hospital in a few days, it will be fine."
The doctor on the side gave Xu Yi a strange look.
Bought? So the little guy lying on the hospital bed must be a slave.
This Xu Yi is really a weirdo, he is so kind to a slave.
You must know that this medical clinic is the best medical clinic in Bangta City, and the treatment fee is not cheap at all.
The little slave still clung to the hem of Xu Yi's clothes, the fear on his face became more and more intense, as if he was afraid that Xu Yi would leave him alone.
Seeing this situation, Xu Yi could only sigh helplessly, turned to the doctor and asked: "What if I take him home? Will he be in danger?"
"Well... he is actually just a few flesh wounds, nothing serious. There is no problem in taking him back. As long as he takes medicine regularly and comes here every three days to change the wound medicine."
"Well, I'll take him back first. The bed here is still reserved for him, and I will pay the hospitalization fee."
The doctor couldn't help but look at the little slave on the bed.
This kind of treatment, let alone slaves, would be difficult for even children from ordinary families to enjoy.
It took Xu Yi a lot of effort to bring home the little slave who was so tightly wrapped that he could barely move. After finally settling him down and serving him the medicine, Xu Yi was already sweating profusely.
Looking at the little slave who fell asleep after taking the medicine, Xu Yi let out a sigh of relief: "Huh... I told the Brunei housekeeper that I bought him to serve me, but now I am serving him."
Even in a sleeping state, the little slave still had a look of pain on his face from time to time, which shows how difficult his daily life is.
Looking at that thin little face, Xu Yi sighed, shook his head, turned around and took a shower, and continued to study the magic circle.
With Wella's help in researching the magic array, the research progress of the variable speed magic fan has been much faster. What needs to be done now is to design the most suitable shape based on this magic array.
Xu Yi originally wanted to take advantage of the launch of the second version of the magic fan to significantly improve the performance of the magic fan. However, after detailed research, he found that he encountered two decisive problems that he could not avoid.
The first problem is the material problem.
The industrial base on Sainz's continent is almost zero. Although there are some handicraft products, most of them are only selected natural materials. Even if they are processed, they are only roughly processed. The various properties of the materials are far from those on earth that have gone through various processes. Finely processed materials are on par.
For example, for a fan, the core part is undoubtedly the motor. This is replaced by Xu Yi's wind vortex array.
But for the core bearings, which are as important as the electric motor, Xu Yi has not been able to find a better replacement for the time being.
Those electric fans on Earth can use high-density, high-wear-resistant alloy materials to make bearings, but they can only be made of ordinary iron on the Sainz continent.
The iron smelting process in this world is also not as developed as on Earth. The quality of the smelted iron itself is not high. Even if it is polished, the quality of the bearings made will not be much higher.
When Xu Yi made the first version of the magic fan, he was very worried about the quality.
The service life of electric fans on earth can reach 10,000 to 40,000 hours, but according to Xu Yi's calculations, the service life of the first version of the magic fan will never exceed 3,000 hours.
Based on the fact that each fan is used for eight hours a day and used during the hottest three months of the year, the first version of the Magic Fan can only last for four years at most before ending its lifespan.
And if it were like Heinze who used it almost all day long, I'm afraid the two magic fans in his home would be scrapped next summer.
It can be said that the material problem is the most serious problem that restricts the quality of the magic fan, but Xu Yi has nothing to do now.
Material technology is the most basic but also the most complex part of the industrial system. It involves all aspects of the industrial system. It is extremely difficult to improve this area even on earth, let alone in Sion, which has almost zero industrial base. On the Sri Lanka continent.
The second problem is the production process.
There are no standard machine tools like those on Earth on the Sainz continent. When Xu Yi made the first version of the magic fan, he could only find the blacksmiths at the blacksmith shop and ask them to forge it according to the drawings he drew.
It should be said that the craftsmanship of these blacksmiths in Bangta City is still very good, but no matter how exquisite the craftsmanship is, it cannot be compared with the precision machinery on the earth. The fan casings they create are always slightly different.
Although this is not a big problem now, Xu Yi is very clear that if he wants to significantly increase the output of magic fans, he must embark on large-scale production, which requires perfection in every aspect of the production of magic fans. , at least there must be a completely unified standard.
"Cutting machine tools, sliding tool holders, punching machines, drilling machines, boring machines...ah, let me die!"
Thinking of the various problems that need to be faced to achieve mass production, Xu Yi couldn't help but let out a wail in pain.
