Lao Li sat there, maintaining the way of teaching, slowly picking up, polishing, and throwing away, and did seven or eight bends one after another, before stopping.

Turning off the roaring machine, he stood up, turned to face the three teenagers, and asked with a smile: "It's a very simple operation, it's easy to get started, which of you will try it?"

The three teenagers glanced at each other, and Yuan Wei took two steps forward, turned sideways to let Lao Li go, and sat down on the small bench.

He didn't rush to experiment, but felt the feeling of sitting here, and suddenly a strange feeling surged in his heart, or rather, a strange feeling swelled up again......

The height of the seat as well as the machine, with his height, sat just right. Jiang Cong should also have no difference, and if Peng Qiao sits like this, it will be a little uncomfortable after a long time. He really couldn't imagine how Lao Xiang, who was so tall, managed to work in this position!

Thinking like this in his heart, he subconsciously turned his head and looked at Lao Xiang.

Lao Xiang and Lao Li were ignorant of this, and they didn't realize the special meaning. Jiang Cong and Peng Qiao understood it, and then glanced at Lao Xiang, who was still muttering in his heart, not knowing what kind of experience it was like to sit on it.

Shaking his head to dispel the strange feeling, Yuan Wei adjusted the position of the seat and moved it forward. Learning to sit down like Lao Li, he leaned forward slightly, rested his elbows on his thighs, and put his hands together in front of him. Pretending to hold the elbow in his hand, he raised his arm slightly and sent it forward, then turned his wrist and skimmed it......

"yes, that's pretty much it, you have the bend in your hand and try again. Lao Li shouted at the right time behind him, affirming Yuan Wei's experiment.

Yuan Wei paused, turned sideways, and reached into the bamboo basket with his right hand, about to get the bend.

Lao Li suddenly stretched out his hand and made a stop gesture, and shouted again: "Wait a minute, it's better to put on gloves." ”

Then he turned to Lao Xiang and asked, "Lao Xiang, do you still have gloves?" Take them out and put them on, without gloves it is easy to scratch their hands. ”

Lao Xiang nodded, didn't speak, and turned around and walked directly to the other side of the door.

On the other side of the door was a mess of things, including an abandoned wooden cabinet. His hand went in, and when he came out again, he felt for his hand and pulled out three pairs of it......

Lao Xiang handed the gloves to Lao Li. Lao Li was not polite, and began to distribute after receiving it, one pair for each of the three teenagers.

Jiang Cong was speechless for a while, and he couldn't help but glance at Lao Xiang again. This black-faced uncle seems to be very restrained, and he seems to have a fight with himself......

What a simple matter, can't you distribute it to us directly, you have to change hands once.

Yuan Wei took the gloves and put them on, feeling pretty good. The weather was already a little cold, and my hands were just bare, and they had begun to resist the invasion of the cold, but now it was much warmer.

He picked up a bend, followed the previous steps, tried it again, and reversed his hands, going through all three ports.

He went through the whole process three times in a row, and then spontaneously started the machine.

In the roar, Yuan Wei's heart began to tense. The previous experiments were just plays, but now it's real, and it seems a little scary to think about. If you accidentally slip, your hand and arm rub against the rotating grinding wheel, you will be wasted if you are heavy, and you will lose a piece of meat at light!

Yuan Wei took a deep breath, his hand holding the bend tightened, and he was about to try to put it on time on the grinding wheel, when Lao Li's voice sounded at the right time: "Don't be afraid, don't panic." When you first do it, you may feel like there is a strong collision, the bend will bounce, and your hand will be numb, but that is normal, so be steady. ”

Yuan Wei thought about it and understood what Lao Li meant. Just like driving a tractor, the tremor of the fuselage and the hand holding on the body will also tremble, and when it comes into contact suddenly, there will be an illusion of rejection and resistance.

He took another deep breath, gripped the elbow with both hands, and slowly leaned towards the rapidly rotating grinding wheel.

Jiang Cong and Peng Qiao subconsciously held their breath and witnessed this magical scene. Even Lao Li and Lao Xiang, the two old rivers and lakes, became nervous. For them, I'm afraid they can do it with their eyes closed, but for pure newcomers, it's really a bit worrying.

Under everyone's nervous gaze, the elbow held by Yuan Wei finally came into contact with the grinding wheel......

......Suddenly, there was a shrill grinding sound, and then it fell silent, except for the roar of the machine itself.

"I'll ......," Yuan Wei exhaled in a low voice.

Although I was mentally prepared and thought that the direction of preparation was also right, when the elbow touched the grinding wheel just now, the sudden tremor almost bounced out of the elbow, and the hands were even more misaligned, and even the body with a slight forward leaning forward swayed back and forth.

At that moment just now, his heartstrings suddenly tightened, and a tingling sensation skewed up from his back, rushing through his spine to the door of his head......

Although it is only sudden and abrupt, it is a feeling that is by no means unfamiliar, and everyone should have experienced it more than once, it is the body's instinctive reaction to danger.

"It's this kind of rejection tremor that seems to be dangerous, but it's just your first encounter, and when you experience it a few more times, this feeling will slowly disappear. Lao Li said behind him.

Yuan Wei glanced back at Lao Li, didn't say anything, and turned his head again, preparing for a new round of attempts.

But this glance actually has a deep meaning, but this time even Jiang Cong and Peng Qiao didn't understand it.

Because he was more cautious, Yuan Wei had been slowly trying to make contact, and then he was shaken away and bounced.

It looked like everything was the same, but this time he was really mentally prepared, and his body never had that tingling feeling again.

After several attempts, the grinding wheel and the elbow touched again, no longer separated by a touch, but an intimate lingering.

The shrill grinding sound of "Ziang Ang ......" continued, and sparks splashed in all directions......

Yuan Wei's expression was solemn and full of endless solemnity. His hands are steady, and his body is steady. Although his movements are not so smooth and his spins are not mellow, he has already made it through the toughest moments!

Everything is difficult at the beginning, and slowly Yuan Wei can already operate freely. Although the process is still not smooth, after the tempering of time, it will not be too far away.

After being slightly proficient, Yuan Wei retreated and replaced him with Jiang Cong.

Also starting from scratch, Yuan Wei's success has a lot of reference and gives Jiang Cong a lot of inspiration, some unnecessary accidents, the greatest extent of weakening, or disappearing, so he spent half of the time......

When it was Peng Qiao's turn, he felt it, readjusted the seat position, and then mastered the initial process faster than Jiang Cong.
