Su Su came soon, Xiang Bei took out the map he had drawn before, according to what Hao Pang said, this picture is just an appearance, without any explanation, without any decomposition, all the data has to be explored by Su Su himself, it is not a drawing.

Hand the diagram to Su Su: "This thing is called a bearing, can you tell what it does?"

Su Su frowned and quickly shook his head.

Xiang Bei told her: "Imagine what would happen if you put this thing under the carriage and put the axle of two wheels in this circle?"

Su Su now understood: "The ball in the two rings on the picture, if it can be rolled, the wheel will rotate very smoothly." Horses can save a lot of effort. ”

"It's professional, it's a little bit of a thing. But there's more to it than that, can you make this thing?"

"Let me think about it," Su Su looked at the drawings, "With these few parts, the refiner can easily do it, but how to put them together and not let them get separated." ”

Su Su muttered to himself, and suddenly patted his head: "Yes, sir, you can't see it in this picture, but the inside of this big ring, and the outside of the small ring, should have grooves, so that the ball will not break away if you put it in." ”

Xiang Bei picked a thumbs up and asked her to continue.

Su Su thought of the difficulty again: "But in this way, the space between the two rings is larger than the edge, and the ball needs to fit into the middle space, how to put this in." It's easy for us to refine parts, but to refine them like this at once, we need a high-level refiner, and we can't do it. Then we have to refine it all the way and assemble it, how about that?"

Su Su thought hard, and Xiang Bei told him that there were only a few refiners in his own house, and this thing, he didn't want three or five, it would be mass-produced in the future, so it was best to set up a set of processes that ordinary people could process.

There was a problem for Su Su again, she said that this iron ring and slotting are easy for ordinary people to do. This ball can be pressed with molten iron, and then polished after pressing, but then again, at present, it can be refined first to experiment, but the sleeve that fixes the ball must be refined, it is too thin, if you use other methods, I am afraid that there will be more waste than the finished product.

Xiang Bei said that he understands that with the craftsmanship of this world, it is true that the smaller the object, the more impossible it is. Tell him that he can divide the labor to do it, and that those who should use the refiner will also use the refiner. Anyway, low-level refiners are not expensive, not worse than a few dollars, but more expensive to sell.

Su Su said that it would be easy to do, and the remaining question was how to put it together. He told Xiang Bei that he had to go back and gather other refiners to study.

Xiang Bei said yes, just let him study, keep improving, and simplify the production steps as much as possible. Remind her that objects will swell when heated, and the steel will burn red, and it can be shaped freely, and if you feel that you can't put it in, you can start from this aspect.

Su Su suddenly brightened: "I understand, don't worry, sir, it will be made soon." But how old is the gentleman?"

"You don't care how big it is, just make it. The specific size standard will be determined later, because I need various models. ”

"Understood" Su Su finished speaking, and he was ready to leave excitedly to try.

Xiang Bei asked her to wait for a while and told him, "Select the refiner you are most optimistic about and set up a special research and development team." If these people in the Xiang Mansion can't do it at the moment, go outside and find it for me. In the future, there will be things for you to make, and money is not a problem. Confidentiality work must be done well. ”

"I understand what Mr. means, but my sister ......"

Su Sugang wanted to recommend her sister, but Xiang Bei interrupted her: "Your sister can't participate in any Xiang Mansion affairs for the time being." ”

"Oh" Su Su was a little disappointed, and Shi Li said goodbye and left.

Chu asked Xiang Bei with pity, why didn't he just tell Su Su how to make it.

Xiang Bei spread his hands: "Because I don't know either, let me do it only by trying various methods." In the words of the fat man, leave the professional things to the professionals. I'm not necessarily better than them. ”

"The fat man can still say such a reasonable thing, but I just thought about it, your so-called bearing is really important. If we install this on all our grain and grass chariots, the efficiency can be improved a lot. ”

"At least twice as much, but that's nothing for the role of the bearing. You will see it later. ”

"Reliable, my family is reliable. Chu praised with pity.

Xiang Bei was unhappy: "It's not the first time you've said this, but no matter how reliable you are, you've never given me a salary increase." ”

"Hmph, it's like you're short of money. It's okay now, I thought you were doing it yourself, but I didn't expect you to learn to be lazy, so just accompany me into the palace to watch the performance, give them guidance, aren't you a cultural person. ”

"I think you have a conspiracy, and you're so interested in this, you can usually watch it if you want to, right?"

"Hehe, let's go. Chu took pity and walked out of the house, and Xiao Lili was trying to grow a small sapling in the yard. Chu pity told her not to practice first, and to play with the two masters in the palace.

"Ah, are you going to find Doudou?" Little Grains was overjoyed, and ran over after receiving the spell.

Xiang Bei picked her up: "You and Doudou are so good?"

"Well, we're going to marry Jin Lan. "Xiao Lili is serious, and it seems that he has a deep relationship with Doudou. It's just that I don't know if this righteous knot Jin Lan is just a playhouse.

The three of them went to the palace, Chu pity that he didn't go out like Xiang Bei, there must be guards and maids, and it would be troublesome to look at. Chu said that he didn't want to, but he had no choice but to stipulate that these people couldn't bring it.

When they came to the palace, Feng Yilei, who was patrolling, saw them and came forward: "See the princess." ”

"You're so polite, do you have something to say to your boss?" Chu pity chatting with them very casually.

Feng Yilei said no, but he didn't see him for a few days, and he missed it a little. But the festival is approaching, the palace is very busy, and there is no time to pass.

Xiang Bei's eyes lit up: "Lao Feng is fine, I'm not here to play with you." Xiang Bei told Chu pity: "You take Xiao Lili to watch the show, and I will patrol with Brother Yilei." ”

Chu pity disagreed: "He is a dragon guard commander patrolling a bird, I'll go and talk to the king, give him a holiday, and you can have a good chat at night." Now you come with me, and your business. ”

Xiang Bei understood: "Princess, you really hold back when you pull me here, I'll just say, how can you be interested in singing and dancing, especially if it's just a rehearsal." What the hell do you want to do?"

"I think you'll improvise and sing a song or something. For the sake of the performance, I prepared a few dancers to accompany you when the time came. You give it a try with them. ”

"Is that improvisation?"

"It looks like it's improvised. ”

"No, I'm not going, you can play by yourself. At that time, I didn't even have any interest in improvising, so we walked away and ignored her. ”

Xiang Bei grabbed Feng Yilei's shoulders to open the way, and Chu exclaimed pitifully: "Hey, do you still put the princess in your eyes?"

Xiang Bei turned around and replied, "I suddenly lost my sight today, forgive me, princess." ”

Saying that, he ran up with a thunderbolt, and ignored Chu's cry of pity.

Xiang Bei ran away, and Chu pityfully puffed: "Are you blind in your eyes and deaf in your ears?" ”

Xiao Lili spoke: "Master, we didn't come in vain, let's go find Doudou, okay?"

"Okay, let's go, there's nothing else to do. Chu was depressed and extremely depressed.
