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

However, the process is also very complicated and meticulous. First, it is the so-called coarse grinding. Use sand grinding to smooth the rough edges and angles of the spherical surface. Secondly, apply a layer of polishing paste on the surface of the sphere, and continue to rub the sphere repeatedly with more delicate water sandpaper until there is no trace of cutting.

Finally, it is the so-called essence to shine, and it is constantly rubbed with half-life cowhide, making the sphere bright inside and outside shiny, exuding a crystal clear feeling.

If it was in ancient times, it would have taken a long time to polish it, but now with a polishing machine, it would be extremely convenient and fast. When the machine rotates, the rough marks on the surface of the sphere will disappear at a speed visible to the naked eye, and eventually become very smooth and bright.

There is no need to elaborate on the process. After Wang Guan finished drinking the third bottle of ice black tea, Lu Chongming finally completed the last step of carving.

"Just wash the polishing powder with clean water."

At this time, Lu Chongming handed the sphere to Wang Guan, picked up the mineral water on the table, raised his head and drank half a bottle, and then took a breath. He felt a little tired between his eyebrows and eyes, and obviously this matter was not as relaxed as he said.

To be honest, ordinary sculptors will not be as eager or as anxious as Lu Chongming if they want to complete this work. They will slowly divide it into several steps and complete one step a day. It will not be until two or three days later that the stone will be carved. However, Lu Chongming will do it in half a day. Naturally, more effort and energy are consumed.

"Thanks."

Wang Guan was very grateful and very satisfied.

"A small matter."

Unlike the seriousness and concentration he had just worked, now that he had completed the task, Lu Chongming softly sat on the chair and waved his hand lazily: "I am a little straight-hearted. To put it bluntly, don't mind it. In the future, don't ask me for help in such things that are not technically available. After all, I am a master, and my identity is different, and I can't do cutting jobs."

It was obviously very arrogant. However, Lu Chongming said it in a casual tone, which did not give people a sense of arrogantness. Instead, it was like complaints between friends, which naturally would not make people disgusted, but would find it funny.

Yu Feibai even gloated and said, "The capable ones work harder, we believe in you."

"Click!"

Lu Chongming was speechless, picked up an apple and took it hard, and comforted him for his hungry stomach.

At this time, Wang Guan made a basin of clean water. He slowly cleaned the polished stone balls, washed away the remaining polishing powder. Then he wiped the spherical water stains with a soft towel.

"It is difficult to put the round thing in order. Go back and customize a base, which is easier to place." Lu Chongming suggested, then took out a thicker sponge cushion and placed it on the table, signaling: "Put this, just put it."

Wang Guan nodded, carefully placed the thing on the sponge, and gently stepped back and looked at it.

Lu Chongming's technique is nothing more than purely cutting. After repeated polishing, the stone was carved into a round shape very smoothly, like a sphere.

However, this sphere is a bit special. Under the light, it emits a crystal-clear luster. Especially the black and white colors are spread throughout the sphere. The surface does not seem regular, but if you look carefully, it makes people feel that something strange happens.

"Huh!"

Yu Feibai looked at him twice, couldn't help but blink, and said in surprise: "I'm dazzled?"

“How to say it?”

Lu Chongming said in surprise: "Why do you say you're dazzled?"

"Not dazzled, why do I think this thing seems to move?" Yu Feibai rubbed his eyes and continued to look at it. Not long after, he shouted: "Yes, he really can move..."

"What moves?"

Lu Chongming was also a little puzzled and looked at the stone ball with the flow. Speaking of which, although this thing was cut and figured out by himself, he was focused and focused when working, and did not look at his works at all.

Of course, it is undeniable that Lu Chongming didn't think that a stone ball was good at, so after completing his work, he did not take a look. But at this time, under Yu Feibai's reminder, he observed it a little more carefully.

"Hey, it's strange."

At first glance, Lu Chongming was also shocked. As he looked at the gaze, the black and white mixed colors on the surface of the sphere were like vortexes, slowly rotating.

"Visual illusion!"

At this moment, Yu Feibai reacted and said in surprise: "This thing can actually make the eyes feel illusory. Wang Guan, wouldn't you know it would be like this before, so you insisted on carving the stone into a ball?"

"Maybe." Wang Guan chuckled softly: "I just think there is such a possibility, so I plan to give it a try.

"In other words, at the beginning, you discovered the clue?" Yu Feibai said in confusion: "Why can't I see it? Xiao Ming, did you find this when you looked at the stone just now?"

"No." Lu Chongming shook his head in confusion, feeling a little depressed. A professional person is not as good as an amateur person, which is a big blow.

"I discovered it by chance," Wang Guan explained: "When observing at an arc angle, I accidentally discovered that the mixed colors of black and white seemed to be rotating. I suddenly had a whim. If the stone was carved into a spherical shape, would this dynamic effect be more obvious? I didn't expect that it was really..."

"As for why you didn't find it, it's mainly because the viewing time was too short." Wang Guan smiled and said, "Especially Brother Lu, I would just analyze it directly on the three-dimensional stereoscopic diagram of the computer, and I will definitely not be able to discover 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."

"What do you understand?" Wang Guan and Yu Feibai became stunned.

"I understand why Master always says that I rely too much on computers, and Xiang Yu has no reason to make progress."

Lu Chongming was both grateful and ashamed, "I didn't understand before. I simply thought that my master was referring to me inexperienced and could not accurately judge the inner quality of jade and the quality of appearance. Now I finally understand that using a computer to looking is completely different from looking with my eyes."

"Even if computers can design many works with shapes and list very detailed data, it hinders one's own thinking ability to some extent, and does not have the feeling of a flash of inspiration."

Lu Chongming smiled bitterly, then let out a long sigh, his face filled with the expression of surviving the disaster, and then he couldn't wait to say, "No, I want to call my master immediately and tell him that I really understand his hometown."

While talking, Lu Chongming took out his cell phone and dialed the phone, and then he talked a lot.

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

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

"oh."

Wang Guan smiled and continued to watch the stone ball. He saw that the sphere was shiny and gentle, and the distinct black and white color changed and rotated slowly like a gear.

"Wang Guan."

After a while, Yu Feibai suddenly spoke, "I seem to have an illusion again."

"What illusion?" Wang Guan's voice was a bit distant.

"I seem to see..."

Yu Feibai hesitated for a while, closed his eyes gently, and murmured: "One black and one white, it is rotating like a spiral, and there are even a little light. What do you think?"

"Tai Chi!"

Wang Guanqian asked: "Black and white Yin and Yang fish?"

"You saw it too!"

Yu Feibai opened his eyes, covered his mouth and hit Ayao, "It's true that it's not my illusion. This thing is really weird. You can't look at it anymore. If you continue to look at it, I want to sleep..."

"Sleep? I just want to go to bed at what time?"

At this time, Lu Chongming had finished the call and walked over and said with a smile: "If you want to sleep, wait for dinner before you can talk about it. Let's go, my master wants to meet you and invite you to dinner by the way."

"ah……"

Yu Feibai was stunned and immediately recovered his energy. He hesitated and said, "Go now? Is this appropriate?"

"What's wrong with it?" Lu Chongming smiled and said, "My master is not a human-eating tiger, and he is very approachable. You don't have to be so cautious, as if you are facing a great enemy."

"You are so light." Yu Feibai glanced across his eyes and said with a groan: "You are in a blessing and don't know how to be blessed. The title of the number one jade carving in Xi Lao Nan's school is not a boast. Although he is in a semi-hidden state, he has concentrated on teaching his disciples and has achieved remarkable results. He can be said to be full of students all over the world. Aren't you the beneficiary of it?"

"Hehe!" Lu Chongming smiled modestly, "I have achieved such a small achievement thanks to Master's mistake, and I still need to work hard, and sooner or later I will surpass him."

"You are not polite." Yu Feibai smiled and said, "You are so arrogant, aren't you afraid of people saying you are bullying your master and destroying your ancestors?"

"What? Better than be better than be better than bet. This is the rule set by the master." Lu Chongming said disdainfully: "When every introductory disciple becomes a disciple, the master sternly warns us that if you don't even have the ambition to surpass him, there is no need to learn carving. You can quickly roll the bed and get out of here, so as not to lose face in the future."

"After all, whether you can do it is one thing, and whether you are willing to work hard is another thing."

Lu Chongming was full of spirit and said confidently: "As a disciple of the master, if he doesn't even have this arrogance, then he will be in vain for his careful guidance."

"You can do it, you are awesome."

Yu Feibai praised without sincerity, and then thought: "What gift should I bring?"

"It's enough for a person to fall. At most, he can't bring two baskets of fruits. Master will not mind." Lu Chongming suggested: "If it's really not possible, bring the stone balls over for him to appreciate. Master should be interested."
