ps: Today's first update, ask for monthly pass support.?

Grinding and polishing is easy to say, but easier to do, just a few steps.

However, the process is also tedious and detailed. The first is the so-called coarse grinding, which uses sanding to smooth the rough edges and corners of the spherical surface, and then applies a layer of polishing paste powder to the surface of the ball, and continues to rub the ball repeatedly with more delicate water sandpaper until no cutting marks can be seen.

Finally, the so-called fine polishing is bright, and the semi-raw cowhide is constantly rubbed to make the inside and outside of the ball shiny and bright, exuding a crystal clear feeling.

If it was in ancient times, it would have been a long time to polish by pure craftsmanship, but now with a polishing machine, it is extremely convenient and fast. When the machine rotated, the rough marks on the surface of the sphere disappeared at a speed visible to the naked eye, and finally became very smooth and shiny.

There is no need to repeat the process, anyway, after Wang Guan drank the third bottle of iced tea, Lu Chongming finally completed the last step of carving.

"Just wash the polishing powder with clean water."

At this time, Lu Chongming handed over the sphere to Wang Guan, picked up the mineral water on the table, raised his head and drank most of the bottle, and then took a breath gently. There was a slight tiredness between his eyebrows, and it was obvious that this matter was not as easy as he said.

To be honest, if an ordinary sculptor wants to complete this work, he will not be in such a hurry and in such a hurry as Lu Chongming. People will slowly divide into several steps, and complete one step a day. It wasn't until it took two or three days to carve the stone. However, Lu Chongming got it done in half a day. Naturally, more effort and energy are consumed.

"Thank you."

Wang Guan was very grateful and very satisfied.

"It's a small thing."

Different from the serious concentration when he was working just now, now that the task has been completed, Lu Chongming slumped on the chair, waved his hand lazily and said: "I have a bit of a straight temper, don't mind if I say something unpleasant." In the future, don't ask me for help with this kind of thing that has no technical content. Anyway, I'm also a master, and my identity is different, so I can't always do the work of a cutter. ”

It's obviously very arrogant. But Lu Chongming said it in a very casual tone, not giving people a sense of domineering, but like a complaint between friends, naturally it will not be disgusting, but funny.

Even Yu Feibai gloated: "Those who can work hard, we believe in you." ”

"Click!"

Lu Chongming was speechless for a moment, picked up an apple and took a bite of it fiercely, comforting his hungry stomach for a long time.

At this time, Wang Guan came out with a basin of water. Hold the polished stone ball and wash it slowly to remove the remaining polishing powder. Then use a soft towel to wipe the spherical water stains dry.

"It's not easy to straighten things in the shape of a circle, so go back and order a base, so it's easier to place." Lu Chongming suggested that he get up, then took out a thicker sponge cushion and rested it on the table, and motioned: "Put it here, let's just take a moment." ”

Wang nodded, carefully placed the object on the sponge, and looked back slightly.

Lu Chongming's technique has nothing to say, it is just pure manual cutting. After repeated polishing, the stone was carved into a round shape, like a sphere.

However, there is something special about this sphere, which shines with a touch of crystal shine under the light. In particular, the black and white color is spread all over the sphere, and there seems to be no regularity on the surface, but if you look closely. But it makes people feel that something strange is happening.

"Huh!"

Yu Feibai looked at it, couldn't help blinking, and said in surprise: "I'm dazzled?" ”

"How?"

Lu Chongming was stunned and said, "Why do you say that you are dazzled?" ”

"Don't dazzle, I don't think this thing seems to move." Yu Feibai rubbed his eyes. He continued to look at it, and it didn't take long for him to exclaim, "That's right, it really moves......"

"What moves?"

Lu Chongming was also a little inexplicable, and looked at the stone ball. Speaking of which, although this thing was cut and carved out by his own hands, when he was working, he was so attentive and distracted that he did not look closely at his own work at all.

Of course, it is undeniable that Lu Chongming didn't think there was anything nice about a stone ball, so after finishing his work, he didn't take another look. But at this time, under Yu Feibai's reminder, he observed a little more carefully.

"Hey, that's weird."

At a glance, Lu Chongming was also stunned, only to see that with the gaze of his eyes, the black and white mixed colors on the surface of the sphere were like whirlpools, slowly rotating.

"Optical illusion!"

At this moment, Yu Feibai reacted and said in surprise: "This thing can actually make the eyes have the effect of illusion." Wang Guan, didn't you know that this would happen, so you insisted on carving the stone into a ball? ”

"Perhaps." Wang Guan smiled lightly: "I just think there is such a possibility, so I plan to give it a try."

"In other words, at the beginning, you found out the clues?" Yu Feibai was puzzled: "Why can't I see it." Xiao Ming, when you looked at the stone just now, did you find anything in this regard? ”

"Nope." Lu Chongming shook his head blankly, feeling a little depressed, he was a professional, and he was not as discerning as an amateur, which was also a big blow.

"I found out by accident, too." Wang Guan explained: "When I was observing from an arc angle, I accidentally noticed that the black and white mixed colors seemed to be rotating, and I suddenly wondered if the stone was carved into a spherical shape, and this dynamic effect would be more obvious. I didn't expect it, but it was really ......"

"As for why you didn't find out, it's mainly that the viewing time is too short." Wang Guan said with a smile: "Especially Brother Lu, if you simply analyze it directly on the three-dimensional map of the computer, you will definitely not be able to find this phenomenon." ”

"Why didn't you say it earlier." Yu Feibai complained.

At the same time, Lu Chongming slapped his forehead and suddenly realized: "I understand." ”

"Got what?" Wang Guan and Yu Feibai were stunned.

"I understand why Master always says that I rely too much on computers, and Xiangyu has not grown at all."

Lu Chongming was happy and ashamed: "I didn't understand before, and I simply thought that Master was referring to my lack of experience and inability to accurately judge the intrinsic quality of jade and the quality of its appearance. Now I finally understand that seeing with a computer and seeing with my eyes are completely different things. ”

"Even if the computer can design the shape of the subject matter of the work, and can list very detailed data, to a certain extent, it hinders my own thinking ability, and I don't have that feeling of inspiration."

Lu Chongming smiled bitterly, then exhaled a long breath, his face was full of the demeanor of the rest of his life, and then he couldn't wait: "No, I want to call the master immediately and tell him that I really understand his hometown." ”

While talking, Lu Chongming took out his mobile phone and dialed the phone, followed by a lot of chatter.

"What is he talking about?" Wang Guan was confused.

"I don't understand, Taicang's dialect." Yu Feibai was also a little dazed, and then waved his hand and said, "Forget it, don't care about him." The so-called enlightenment is probably what it looks like. ”

"Oh."

Wang Guan smiled and continued to look at the stone ball. I saw that the spherical surface was lusterly warm, and the clear black and white color changed and rotated, like a gear slowly turning.

"Wang Guan."

After a while, Yu Feibai suddenly spoke: "I seem to have a delusion again." ”

"What delusion?" Wang Guan's voice was a little distant.

"I seem to see ......"

Yu Feibai hesitated, closed his eyes gently, and whispered: "One black and one white, and it is rotating like a spiral, and there is even a little light, what do you say?" ”

"Tai Chi!"

Wang Guan asked, "Black and white yin-yang fish?" ”

"You saw it too!"

Yu Feibai opened his eyes, covered his mouth and yawned, "Sure enough, it's not my delusion." This thing is really weird, I can't look at it anymore, I want to sleep if I look at it again......"

"Sleep? What time do you want to go to bed? ”

At this time, Lu Chongming had already ended the call, walked over and said with a smile: "If you want to sleep, you can wait until dinner." Let's go, my master wants to meet you, and by the way, I will invite you to dinner. ”

"Ah......h

Yu Feibai was stunned for a moment, immediately recovered his spirits, and said with some hesitation: "Go now?" Is that appropriate? ”

"What's out of place." Lu Chongming said with a smile: "My master is not a man-eating tiger, and he is very approachable. You don't have to be so cautious, as if you were facing a great enemy. ”

"You say it lightly." Yu Feibai squinted sideways, and snorted: "You are in the blessing and don't know the blessing, the title of the first person in the jade carving of Xi Laonan's faction, that is not boasting." Although he is now in a state of semi-concealed sealing knife, he has concentrated on teaching apprentices and achieved remarkable results, which can be described as a peach and plum all over the world, aren't you one of the beneficiaries. ”

"Hey, hey!" Lu Chongming smiled modestly: "Thanks to Master's mistakes, I have achieved such a small achievement, I still need to work hard, and sooner or later I will surpass his old man." ”

"You're welcome." Yu Feibai smiled: "So arrogant, aren't you afraid that people will say that you deceived your teacher and destroyed your ancestors?" ”

"What, blue is better than blue, this is the door rule formulated by the master." Lu Chongming said disdainfully: "When every beginner disciple apprentices, the master sternly warns us that if we don't even have the ambition to surpass him, then there is no need to learn carving, hurry up and roll up the cover, so as to save him from losing face in the future." ”

"After all, it's one thing to be able to do it, and it's another thing to be willing to do it or not."

Lu Chongming's spirit was radiant, and he said very confidently: "As a disciple of the master, if you don't even have this bit of arrogance, then it will be in vain for his old man's careful teaching." ”

"You can do it, you're amazing."

Yu Feibai admired insincerely, and then pondered: "What kind of gift should I bring?" ”

"It's okay to be a person, it's a big deal to mention two baskets of fruit, Master he won't mind." Lu Chongming suggested: "It's really not good, bring the stone ball over for him to appreciate, the master should be interested." ”

Wang Guan naturally had no opinion, so he decided to settle down, and then went out to Master Lu Chongming's house......
