You won’t be afraid if you learn mathematics, physics and chemistry well and cultivate immortality

The three people except Old Man Lin all smiled happily when they heard about the gadgets. They all have young minds, and it is impossible to express their joy without expressing it.

Then go for a walk and pick out a small item that you like. Go back the way you came and exit this workshop.

This mecha was shocking when I passed by it just now, and it is still shocking now when I come back. We are all very curious as to whether this is a finished product or a decoration.

"Haha, this puppet machine beast that I just fiddled with according to rumors is just a prototype, and the design is not perfect yet. If you encounter some minor problems, you will definitely be able to come up with a solution after spending some time." Master Lu saw the three little ones. The guy was quite curious and embarrassed to explain.

"Oh, Senior Lu, this is pretty good. Look at this line, look at this texture, look at this shape. It's all great." Just bragging, anyway, the free words are not enough for today's novices. It's a unique skill.

"Yes, yes, yes, yes, good, good, great." Brother and sister Jun Xiangru and Jun Yimo also said flatteringly!

Old man Lin looked on arrogantly and coldly, thinking, that's it? Immortal cultivators dislike the cumbersome and inflexible defense, but the key is that the cost is probably astronomical. Wouldn't it be nice to buy a good weapon and inner armor with this money? .

Mortals can't move as soon as they put it on. This is just a look-alike, so many good materials are wasted.

Black Qiuqiu Wangcai ran over and sniffed it. Well, he couldn't bite it. It didn't taste good. He couldn't afford it, so he slipped away.

Master Lu was immediately lame after being praised by these three little fools. How to put it, it means to eat soft things and not hard things.

"Hahaha, you three guys know your stuff. Let's take a walk and show you the gadgets I've been messing around with." Master Lu was also very happy. Who doesn't like to hear good things?

Turn around the barrier wall and come to the display stand. Take a look and see if you like anything you like. The three of them went straight to look left and right. If they liked something, they picked it up and took a closer look.

Everyone has different preferences and different priorities. It is quite easy to find what you like among hundreds of whimsical gadgets.

Jun Xiangru soon fell in love with a unique dagger. What can I say about this dagger, with its dark body and jagged edge. The tip of the dagger still has a unique small hole design, the handle has scales, and it is relatively heavy to hold.

"The boy from the Jun family has good taste. This dagger is called Shadow. It is made of meteorite iron. One side has an extremely sharp blade, which can easily blow hair and break hair. Don't underestimate the sharpness of the toothed blade on the other side. It can be easily To cut the fine iron, just cut back and forth. Check whether the button on the dagger is turned on. When pressed, the powder will be sprayed out about one to two steps away. Twist the back of the dagger to hold the finely ground powder. This is now filled with It's Ruanjin Powder, as long as you inhale some of it, even a cow will be powerless for a stick of incense." After the introduction, he handed the dagger to Jun Xiangru.

The little rookie is watching carefully, oh, this is a simple spring leaf stamping design. But it is a powerful weapon for self-defense. I will use the dagger to fight you in close combat. I will press the mechanism while making gestures, and spray some powder from the tip of the dagger, directly making the opponent fall down.

It's just that the shape of this dagger is a bit off. One side has a blade, the other side has teeth, and there's a snag on the handle. However, the shortcomings were directly overshadowed by the advantages. Jun Xiangru fell in love with this dagger, carefully inserted it back into the sheath and couldn't put it down.

Jun Yimo, on the other hand, was not interested in weapons. When he saw a small box with straps, he felt that it was very interesting.

"This is a hidden arrow box called Tianwai Feixian. It is suitable for women's self-defense. This strap is made of beef tendon and is tied to the arm. Look at the pick in the groove. You can shoot a needle to the left. This There are three needles in the box. The first two needles are shot out as soon as they are shot. The third needle is an umbrella needle. It has a hole at the end of the needle and is tied with silkworm silk. However, this filament is only three feet long. There is a dial next to it. , you can recover it by turning it. Xiao Qinggong is better at running around and borrowing the magic tool. Turn it to the right. At this time, you can shoot about a dozen fine needles from this box. However, there is no accuracy. The needles are all quenched and soft. Jin San, if you are accidentally shot, haha, it will take effect in the fastest five breaths, and you will have difficulty moving in at least half a cup of tea. It is a sharp weapon for counterattacking when being hunted." After Master Lu introduced it, he put the hidden weapon box Pass it to Jun Yimo.

Jun Yimo also likes it, mainly because it is small, light and very practical.

When it's the rookie's turn, there's nothing to look at. He doesn't have access to small weapons for self-defense, and he doesn't need concealed weapons. Then keep looking, well, I finally saw something interesting, this is a wooden rabbit.

"This is a small puppet mechanism toy. Spin the rabbit's tail a few times and then place it on the ground." Master Lu introduced.

The little novice followed the instructions. The rabbit was able to run quickly, but it stopped after only ten steps. This is interesting. It is obviously similar to the tin frog toy. Add to cart.

Looking up, I actually saw a big dragonfly toy. The little rookie was thinking that he was indeed a skilled craftsman and a well-known weapon refiner in the world of immortality. Needless to say, it can fly by spinning its tail a few times and gliding parallelly in mid-air. This is not just a manual version of a toy airplane.

He looked up at Old Man Lin and gave him a look, which meant that he had taken your place.

The remaining ones are either mediocre, weird and ineffective, or neither attractive nor useful, or they are just not needed.

However, most of them are only whimsical without wonderful ideas, or only whimsical without anything extraordinary.

Okay, as long as you have selected the gadgets you like and are satisfied with them.

It took a long time to select things, and the enthusiastic Master Lu started to leave food. It was time to have lunch. So he led everyone in front and walked towards the row of huts inside.

Actually, the purpose is to get some distilled wine brought by Old Man Lin to satisfy his craving, that's all.

To eat, as the saying goes, you have to rely on mountains and rivers to eat. The blacksmith shop in this backing arranged to roast wild sheep at noon. The sheep was caught by a young man named Tie Zhu, who was actually Master Lu's apprentice. This was too self-reliant and self-reliant.

Chef Tiezhu brought a large pot of mutton soup with pancakes, plus secret roasted whole lamb, and the aroma was immediately delivered to the hospital. This made Xiaoji, who was good at barbecue skills, give up the comparison.

Just by looking at Xiao Wangcai's famous halazi, you know that the outcome will be decided. Wangcai "ooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo

When eating, pay attention to the atmosphere, just sit wherever you want. Master Lu brought his two direct disciples, Tie Hammer and Tie Zhu, to accompany the guests. The other apprentices each made a large bowl of mutton soup, took two large steamed buns with some roasted mutton, and sat down wherever they wanted to eat.

This meal was a feast for both guests and guests, because Old Man Lin contributed another jar of distilled wine.

Seeing Master Lu's thirst for wine, the novice was wondering if the Immortal Cultivator family who was chasing this guy was stupid. As long as they had enough wine control, they could probably call this guy anything they wanted. He's in so much trouble and still pursues him.

After having had enough wine and food, let's part ways. The brothers and sisters wanted to say goodbye and leave. They were traveling around and making friends. This time they not only met the young hero Musk, but also the skilled craftsman Master Lu. It's a worthwhile trip.

I was ready to say goodbye, to continue traveling, and to bid farewell to everyone. Before leaving, I gave a gold waistband to Musk solemnly. Everywhere can be accessed without obstruction, and brothers and sisters can be found who help each other.

Well, say goodbye to these brothers, oh, no, they are brother and sister.

Although the little rookie felt a little reluctant to give up, after all, they were able to chat with each other for several days. But they are both young, and there is no place in the world where we would not meet each other.

The promised wine had not been produced yet, so there was no rush to leave. He followed the carriage to the cabin behind the blacksmith shop, found an open space to place the carriage, and then led the two horses to the stable to tie them up.

After finishing these tasks, I picked up the puppet rabbit and giant dragonfly that I selected at noon, went to Old Man Lin, and asked him to take them back to Jia's Mansion for my sworn sister to play with. Old man Lin took it and put it away, then piled the gift boxes and some clothes prepared for the Jia family in the storage bag into the carriage.

Everyone knew it was time to say goodbye, so Musk behaved himself and respectfully gave Old Man Lin a junior salute.

"Thank you Grandpa Lin for your care and preaching. The younger generation Musk will definitely remember this kindness. If you want to help me in the future, I will try my best to repay you." Musk said to the sweeping monk sonorously.

"Well, I got it. Practice hard. Master Lu and I are close friends. I have already told him that I will take care of you. I hope that next time I see you, not only will your martial arts skills be outstanding, but your Qi refining realm will also follow suit."

Old man Lin waved his robe very freely, and a small sword appeared. Then the small sword became larger. When no one was looking at him, he lightly jumped on the sword and flew away towards the back mountain.

Musk cupped his fists and bowed in the direction where the sweeping monk was flying with his sword. This was not only an escort and companionship along the way, but also the grace of preaching and solving doubts as both a teacher and a friend. Actually, Musk was thinking that he was going to kowtow three times to Old Man Lin, but it’s a pity that immortal cultivators don’t like this.

Non-vegetation, ruthless Practice makes perfect. After bidding farewell to the sweeper, the little rookie still felt a little uncomfortable or slightly melancholy about parting.

But Diamondback himself is not the kind of mother-in-law, sentimental person! There is a positive, optimistic and cheerful young man living in his body.

Musk’s Soul Transmutation has been a game so far, and many things have to be done in a hurry. He has no real meaning to plan his life. Perhaps this parting has made him firm up his hesitant decision from now on. He must cheer up and return to his hometown to meet his relatives after finishing what he needs to do. go.

In my heart, I have always been a little worried and evasive about this matter. Since I have to face it sooner or later, I should face it openly and accept it calmly, and give an explanation to myself and the original owner of this body.

People treat me with courtesy, and I treat others with sincerity. When you look up, you are not ashamed of the sky, when you look down, you are not ashamed of the earth, when you look up, you are not ashamed of others, and when you are inside, you are not ashamed of your heart. If you advance, you will not be ashamed of God; if you retreat, you will not be ashamed of yourself. When the body is upright, the mind is at peace.

The four-year-old young man in his late twenties finally regained his composure and quickly adjusted his mentality without worrying about how old he was.

Hey, it’s me again, oh, no. There is also a black ball that brings prosperity and wealth.

During the dozen or so breaths of the wandering mind, his robe was bitten by something. No need to look at it, he was undoubtedly prosperous. I lowered my head and saw that it was indeed this guy. This little guy who released his nature was covered in black and gray. He was running around in the blacksmith shop and could still be clean. It didn't matter. He stepped on the melon skin and slipped wherever he went.

Let's get things done while the ideas are clear. Since this Master Lu is a thick-legged man, let's make win-win arrangements in advance. First, come up with the idea of ​​bearings and see if they can be reproduced perfectly. Even if it's just a little bit accurate, at least it's time-honored. product.

I mainly use it on the badly worn carriage. Although I replaced the shaft more than ten days ago, it still means changing the soup without changing the medicine. There is no fundamental solution. Sooner or later, it will break, and it will all go to the master of the weapon refiner. If I don’t have a high-end match, I’d be sorry for spending so much money on the wine.

The bearing graphics obtained by Master Lu can be used in more fantastic ideas. This is a win-win and mutually beneficial thing.

If you think of it, do it and find someone. It was still the same place in the morning, and we just met each other when we stepped in.

"Is something wrong?" Master Lu raised his head and asked.

"Senior Lu, I have something to do. I don't know whether I should talk about it or not." The rookie replied, thinking about his words in his mind.

"Oh, just tell me anything. Old man Lin asked me to take care of you. I'll do it for you if I can." Master Lu asked directly without any hesitation.

"It's like this, I have an object I want to build, see if you can make it." After the rookie said it, he was thinking about how to draw it.

"Well, I'm building something. Do you have a sketch? If you do, show it to me." Master Lu agreed simply and clearly.

"Ah, I don't have this sketch, but I can draw it for you to see." The rookie told the truth.

"Well, then you draw it!" After saying that, he pulled out a half-drawn piece of paper from under the table and handed it to the rookie.

The little rookie didn't mind it, so he took the paper and the pen directly. It looks like it's a writing brush, but I'm not used to it. what to do?

Simple, thump thump thump, I ran out and picked up a small piece of charcoal by the blacksmith's stove and came back. The brush is so soft that I'm not used to it, but the charcoal brush is very easy to use.

So I drew a roller bearing. At first, I drew Master Lu's eyes as if he were watching a play. After the prototype was drawn, the rookie introduced and explained it. As a well-known weapon-refining master in the world of immortality, he can directly understand the magical effect of these circles.

It also reminded him that this would play a vital role in the puppet mechanism technique he was currently studying. So he shouted three words with a flushed face.

“good good”

The class representative said: The main function of the bearing is to support the rotation of the machine, reduce the friction coefficient during its movement, and ensure its rotation accuracy. It can be understood that it is used to fix the shaft so that it can only rotate and control other axial and radial movements. If the shaft does not have bearings, it will not work well. Generally speaking, the most common ones are rolling bearings. Ball bearings and roller bearings are both rolling bearings.

In the simplest terms, a rolling element is a ball, which is a steel ball. The other rolling element is a steel column. Generally speaking, roller bearings have better radial pressure bearing than ball bearings, but their rotation speed is lower.
