Although Yan Juan was concentrating on carving, Yan Yixin's half-proud words were still heard very clearly. I only felt that the warm current in my heart seemed to have just blown from the South Pacific, and I was a little drunk.

Cheer up, Yan Juan's work was done very well, and even Liu Li whistled in surprise: "Yan Juan, are you sure this is the first time?" ”

Yan Juan's face was a little red: "I used to ......"

This question seems to sound a little wrong.

Yan Yixin walked behind her and picked up a cleaver on the workbench: "Good job." ”

Yan Xuan's face turned even redder, and he watched in surprise as he put the knife in his hand: "This...... You're asking me to ......"

Even if her real age is in her twenties, she is not far behind Yan Yixin. But what was sitting under the knife was a diamond! Even if there are flaws, but if it collapses, it is not something that her pawn house seller can afford!

"You've seen the Ann chisel, try to put it and see where the capillary is more appropriate." Yan Yixin's voice was still very stable, as if under her knife, it was just a stone picked up at random on the side of the road.

Yan Juan felt that his mouth was dry, but his palms were damp, and the sweat made the handle of the cleaver a little slippery. A thin silk was handed to his hand at the right time, Yan Juan raised his head slightly, and saw Yan Yixin, who was standing close to him, with a gentle smile on his face, and there was encouragement in his eyes that could not be ignored.

Liu Li also looked stunned: "Yixin, do you want Yan Juan to do it himself?" She...... Will it work? ”

Compared with the performance of the two people, Yan Yixin was very relaxed: "Don't be nervous, I just want Yan Juan to put the position of the chopping knife and try her feelings." ”

Liu Li breathed a sigh of relief: "Your brother is too big, right?" ”

Yan Juan's mood finally relaxed, and he became nervous again because of his words.

Yan Yixin held her hand holding the cleaver with her hand: "Don't be nervous, it's not for you to chop down." If it doesn't fit well, I'll put it back up. ”

Liu Li came back to his senses and whistled: "Don't worry, even if it is broken, he can afford to pay for such a defective diamond, and he will not go bankrupt." ”

Yan Juan once again decided that Liu Li just gave birth to a face that was softer than a woman, and he hit people without leaving any back, and he was not far behind with ruthless politicians and the like.

Yan Yixin glared at Liu Li: "Don't say a few words, no one treats you as a dumb person." ”

Liu Li smiled very badly: "Yixin, I'm just telling the truth, can you be so angry that you rush to the crown?" ”

Yan Juan hurriedly looked at Yan Yixin, and it was clear that he still looked light and breezy! When he was talking to Liu Li, he didn't even raise his eyelids, but just held her hand and tightened it.

"It's okay to see for yourself where you put it." He comforted, took his hand away, and directly treated Liu Li is air.

"Hmm." Yan Wan froze and recalled Ann's movements, as if he was slowing down the camera, and every hand movement was as clear as a moment. My heart suddenly calmed down, and all the nervousness was thrown out of the clouds.

She didn't even take a deep breath, she simply put the chopper into the slit she had carved, the sides of the blade against the two walls of the groove, and the chopper was held upright by her left hand.

"Yan Juan, you did it very professionally." Yan Yixin's praise made Yan Juan smile.

"Would you like to correct the angle?" She asked. Maybe he learned Yan Yixin's two points of calmness, this sentence, his voice was actually very calm, and there was a faint sense of confidence.

"No, you have a good angle." Yan Yixin said, picked up the wooden hammer, "Hold steady." ”

Yan Juan agreed, not yet understanding his intention to speak, his hammer had already struck the blade accurately and quickly and gently, and the crystals of the diamond cracked along the expected cleavage plane.

Stunned, Yan Xuan's hand was still tightly gripping the handle of the cleaver, and his eyes looked at the diamond that was divided into two halves for a moment, and the entire surface of his face was paralyzed.

"Perfect!" Liu Li stretched out his hand and easily picked up the diamond, "In the end, you have a heart, even the cooperation is so intimate." ”

That's it - done? Yan Juan was still a little unable to come back to her senses, when Yan Yixin took the cleaver, she still held it very tightly, and after being stunned for a while, she relaxed her strength and let Yan Yixin smoothly put the chopper on the workbench.

"It's that simple, it's not difficult, right?" He gently put her small hand into his big palm.

It's not difficult, before she could react, she had already dropped her handle and completed all the processes. If she blinked, she couldn't see the process of the diamond's disintegration at all......

It's just that the heart, but it is very angry, and it is still beating loudly, and the frequency has not returned to the usual rhythm.

"It's time for coarse grinding." Liu Li handed the diamond to Yan Juan's hand, "Look at the result of your cooperation, it's really unimaginable, you are the first time to chisel, and you don't even show a little excitement. ”

Yan Juan looked at Liu Li's appreciation, a little weak. She's just stunned, that's why she's expressionless, okay? Until now, her little liver has not recovered!

The two diamonds are not much different, and they already have the rudiments of a round and multifaceted shape. The inclusions are split at the waist, and the edges of the two diamonds can be further polished off through subsequent processes, and basically nothing is wasted.

Such a result is ideal.

"It's a kibble grinder, and we put two diamonds in it, one in the opposite direction of the other. And, of course, artificially changing the direction of rotation. Yan Yixin held Yan Xuan's hand and led her to another machine.

Although Liu Li's mouth is a little sorry for the audience, his ability to do things is first-class.

"Coarse grinding is mainly to grind out the waist shape of the finished diamond, which is directly related to the yield and value of the finished diamond, so each step should be carefully designed." Liu Li also explained on the side.

"Oh, so what direction and speed are you going to design?" Yan Wan asked.

"The key is to determine the center line of the best design shape of the drill billet to be turned, and ensure that the center line of the drill, the axis of the sticky rod and the axis of the drill rig coincide."

"It sounds like a difficult look......" Yan Qian said to herself.

"It's not hard." Yan Yixin smiled, "Now there is a computer, which can calculate it very accurately." ”

Yan Juan found that on the chair of the workbench, the notebook had been opened.
