"This is just used to help Wanbao Pavilion customers repair damaged utensils, and my workshop is not here."

"It turns out it's just an after-sales repair point!" Tianyou sighed in a low voice.

"What did you say?"

Tianyou didn't expect Feng Wu's ears to be so good. He just muttered a few words and was heard. He quickly changed the subject and said, "I'm so anxious to come here. Is there anything to show me?"

Feng Wu's attention was indeed immediately shifted, and he suddenly became excited. He jumped and ran to the corner of the room, then pulled off a large ball of linen covering there, revealing a semi-finished Taoist puppet underneath.

This is really a semi-finished Taoist puppet, with no lower limbs at all, and only the part above the waist is placed on a movable operating table, and there is no shell at all. You can directly see the internal structure and main frame. However, as the so-called layman watching the excitement, the expert watching the tricks. As a time traveler, Tianyou almost discovered the uniqueness of this Taoist puppet at a glance.

"This is..." Tianyou also took a step forward with excitement, reached out and held the arm of the half-Daoist puppet.

Feng Wu introduced to Tianyou with an excited look: "This is a test piece made according to the method you said after you left that day. Unexpectedly, the output was more than doubled, but the consumption of spiritual power was reduced."

Tianyou held the arm of the Taoist puppet with one hand and moved up and down, while analyzing: "The friction is greater than expected, and the material does not seem to be right. This structure... If repeated large movements are done in a short time, it will burn due to the heat generated by friction? Even if lubricating oil is used, the wear will be almost unacceptable. Although the output has increased, the strength of the wood cannot withstand this force at all and has no practical value."

"You know everything!" Feng Wu looked at Tianyou with a surprised look and said, "Actually, the arm of this test machine has been wrapped several times. What you said has happened before. If you put in too much force, the bearing position will break, but this is not a problem. After all, this is just a test product. If you really plan to produce it in the future, I will replace it with a bronze joint, and the wear and heat resistance will be improved. The most important thing is that you no longer have to worry about breaking the shaft."

"No, bronze cannot withstand this level of power." Tianyou denied Feng Wu's idea.

Due to structural problems, the most fragile part of the bearing joint is the bearing itself. Therefore, no matter what bearing, the material strength is necessary. The bronze itself is not very hard, and although the wear resistance is not bad, the wear must be very exaggerated based on the working characteristics of the Taoist puppet. Therefore, a simple rotating shaft must not be used as the joint of the Taoist puppet, and ball bearings must be put on. However, to do this, you must first solve the problem of steel ball production.

With the industrial level on the earth, processing steel beads is simple, but this is the Shenzhou Continent, so it is quite difficult to make a round steel bead. Of course, it is not that it cannot be processed, but it is just a matter of production capacity and cost. If you don’t care about the cost, it can be rubbed by hand. But if you really do that, it is difficult to ensure the uniform size of the steel beads, and the secondly, the time will be very exaggerated. Even if you become a skilled worker after doing too much, it will take at least three or five days to rub one out of it. This bearing costs at least a dozen steel beads, and the cost...it’s scary to think about it.

When Feng Wu heard Tianyou denied his idea, he immediately asked: "What materials should I use?"

Tianyou shook his head, "It's not a matter of material. The bearings I told you before are just the most basic structure. Ball bearings must be used for the types of Taoist puppets that require frequent movement."

“Ball Bearing?”

"It is to increase the gap of the foundation bearing and then fill it with small balls in the gap. When the inner and outer rings of the bearings move relative to each other, due to the barrier of the balls, there will be no friction between the two, but the rolling of the balls instead of direct friction." After Tianyou finished speaking, he saw that Feng Wu was still confused and directly borrowed her drawing board and drew a simple schematic diagram with charcoal brush.

Feng Wu was naturally quite smart to rely on a Taoist puppet to analyze the technology in reverse. With Tianyou's illustration, he quickly understood the principle of ball bearings. However, it was different from ordinary people. Because he was smart enough, Feng Wu quickly discovered the problem with ball bearings.

"This...how do you make these balls? A bearing like this requires several balls? These balls are not only round, but also the same size. The processing difficulty is too high, right?"

Tianyou smiled slightly when he heard this, "Ball bearings are indeed difficult to process, but I have a simplified solution here."

"Tell me quickly, how to solve the problem of ball production?" Feng Wu couldn't wait to ask.

Tianyou did not hide his own privateness. Although the technology belongs to Tianyou himself, it should be kept secret, he and Feng Wu had already communicated with each other a lot of related technologies related to Taoist puppets. The two of them already had a tacit understanding and knew that the other party would not take advantage of them. Although they did not make it clear, the two were actually doing one-on-one exchanges. If you teach me a little, I will teach you a little, and no one will suffer any loss. Of course, this exchange is not so rigorous, and both parties will not deliberately measure the value of the knowledge they provide. After all, they are actually more like a meeting between a technician rather than a commercial technology transfer.

After a little bit of arousing the appetite of Feng Wu, Tianyou directly explained his simplified plan while drawing the drawing board.

In fact, Tianyou’s method is very simple. Since ball rolling is difficult to process, you don’t need ball rolling.

With the technical level of the Shenzhou Continent, processing a large number of uniformly sized small rolls is obviously a time-consuming and laborious task, but it would be different if you don’t use balls and just replace them with rollers.

With the existing technology of Shenzhou Continent, it is not difficult to process metal rods with stable diameters. Then, just cut them into many small segments of equal length and grind the cross sections at both ends to remove the burrs, and you can get small short rods with equal diameters.

The inner and outer rings of the bearing are still the same, but this time, the ball is not used, but the small short rod is directly stuffed between the inner and outer rings to replace the ball. The disadvantage is that the friction resistance will be slightly higher than the ball bearing, and the size of the bearing will be relatively bulky and the friction loss is not as good as the soul beads. However, this is not entirely beneficial. At least, under the premise that the material strength is not up to standard, the larger force area of ​​the small short rod is obviously more compressive than the ball bearing, which means that the strength will be much higher than the ball bearing. For the Taoist puppets used in combat, this advantage can even be said to be more important than the small friction resistance, so it can be said that it is more suitable for the design of the Taoist puppets.

After listening to Tianyou's explanation, Feng Wu was in a state of excitement and felt that he was suddenly enlightened. This simple design is not only widely used, but more importantly, the processing is not difficult. At least Feng Wu is confident that the group of blacksmiths under his command can easily handle it.

"This design is really great." Feng Wu looked at the schematic diagram of Tianyou excitedly and was excited for a long time before she returned to normal. Then she asked some unclear areas. After she figured it out, she suddenly took out a hand-painted booklet from her body and handed it to Tianyou.

"What is this?" Tianyou asked as he took the booklet with a slightly damaged cover.

Feng Wu did not answer immediately, but waited for Tianyou to see the content inside and the expression changed on his face before smiling and said, "This is my years of hard work, enough to empty all the things in your stomach, right?"

Tianyou nodded while flipping, "Enough, enough. Why didn't you take out this thing soon?"

The booklet records nothing else, but the array diagrams that Tianyou has been studying in the past few days.

In comparison, Tianyou, Feng Wu's understanding of the formation diagram can be said to be completely based on pragmatism. She has never conducted systematic formation learning, but has a lot of hands-on experience. She has almost full screen perseverance to test the specific purpose of some formation diagrams on the Taoist puppets.

Faced with Tianyou's complaint, Feng Wu retorted with confidence: "This is all my hard work, how can I carry it with me? I took out all the things in my chest. You can't hide your personalities from me if you have anything."

"It must be." Tianyou's attention was all on the booklet at this time, and he had no time to care about anything else. But after he looked through it for a while, he suddenly felt something was wrong.

This booklet is not very thick, and there are not many pages in total. However, if you want to say that this is someone’s experience, there are still too many things in it.

If you don’t understand the principles of the array diagram, it is like a computer code in front of ordinary people. It is not an exaggeration to say it is a heavenly book. However, Feng Wu tried it out by using the exhaustive method, bit by bit, and tried out the specific uses of several array diagram structures.

This is no longer a matter of pure perseverance. How long did it take to test it? But how old is Feng Wu's appearance? Even if she starts to study this thing at birth, she will not be able to try out the structure and energy supply of so many array diagrams, right?

"Did I say I was wrong?" Tianyou couldn't help but peek at Feng Wu who was studying the bearing drawings he provided. He felt that he was just a little girl!

Shaking his head, Tianyou, who couldn't figure it out, did not worry about this issue anymore, but continued to read the manual seriously.

The array diagram given by Feng Wu includes parts that Tianyou already knew and parts that he analyzed in the past few days, but more of them are parts that he had not understood before. Although Feng Wu didn't understand, she instead introduced the functions of these structures. Tianyou herself has solid knowledge of array diagrams, and the principle of reverse deduction becomes extremely simple under the premise of knowing the result.
