Liu looked at Bu Si quietly and did not urge.

Finally, when Bu San was so anxious that he couldn't bear it anymore, Bu Si stopped and gestured and said: " This crack belongs to the through crack, the length of the whole section to the position of the regolith is 1 meter 372, the straight line according to the degree of bending, the straighter part can be divided into four sections, the distance length of each section is 53 centimeters, 48 centimeters and 36.2 centimeters, the whole crack has seven wider positions, the width is 1.4 centimeters, 1.7 centimeters, 1.9 centimeters, 2.1 centimeters, 1.3 centimeters, 1.6 centimeters and the last tail of 1.4 centimeters. ”

Yang Hao, who had recovered slightly and was not so mentally deranged, was stunned when he heard Bu Si's words.

Really?

This is an analogy to know the exact distance?

Chen Song looked at Bu Si with a positive face, and was secretly shocked in his heart.

Could it be that these two brothers can really visually measure the distance?

"Very well, you can go back first!"

Liu looked at the three and four brothers with an appreciative face.

"Okay, Master Liu!"

Bu San nodded, stepped forward and pulled up Bu Si, who was still fluting against the cut surface of the rough stone, and turned to leave.

Both of them were confused, and they didn't understand why Liu Yiyan suddenly called out to the two of them, so he asked such a simple question as the rift distance.

They had no idea how appalling the question they had just answered.

After seeing the two brothers leaving, Yang Hao asked in a trembling voice, "Master, are what the two brothers said right?"

Liu sighed, took out a tape measure from his pocket, handed it to Yang Hao, and said, "Measure it yourself!"

Yang Hao couldn't wait to take it, pulled out the tape measure, and measured the crack on the cut surface of the rough stone.

"One point four centimeters...... 1.7 centimeters...... 1.9 centimeters...... 2.1 centimeter......"

The more Yang Hao counted, the more frightened he became.

Chen Song looked at the data measured by Yang Hao, and his face was shocked, the two brothers actually said that the score was not bad!

"1.372 meters......"

After measuring the length of the entire strip in the middle, Yang Hao directly gave up and continued to measure.

Obviously, the two brothers were right.

He put the tape measure away, sat down on the ground with a look of disbelief, and muttered, "This can't be! ”

There was no error between the answer and the measurement that the two brothers answered just now directly destroyed the only trace of confidence in Yang Hao's heart, and even Chen Song was a little dumbfounded, and the whole person was doubting life.

Could it be that just one person can do it?

Is it your own waste?

Are you really that wasted?

When Liu Yan heard Yang Hao's words, he said angrily: "What do you mean impossible? What did I tell you before? Don't judge others with your own subjective thinking, just because you can't do it doesn't mean that others can't do it either!"

Chen Song and Yang Hao were shocked, and their faces turned red with shame.

The facts are in front of you, forget if you can't do it, and question what others have done.

Yang Hao asked unwillingly, "Master, how did they do it?"

"Practice makes perfect, the two of them are first-class jade interpreters, this is not difficult for them!"

Liu glanced at the two of them with a depressed face, and felt that it was time to give them some confidence, so he said: "The two brothers have been solving jade for many years, and they can achieve the first-class level, which shows that they are perfect for solving jade, and there is no deviation in the tangent line, and the width and distance can be easily distinguished by the size of the crack on the rough stone, and they are even familiar enough to accurately say the accurate distance by looking at it." ”

Chen Song and Yang Hao suddenly realized.

It's no wonder that Bu San can tell the distance of the rift with just one glance.

It turned out that it was not that they were wasted, but that the two brothers faced cracks every day, and after long-term observation, they had already known the length and width of each crack, so that they could unravel the rough stone without deviation.

Liu glanced at the two people who understood, took out a tape measure from his pocket and handed it to Chen Song, and hummed: "I don't care what method you use, in short, I can accurately identify the length of the crack I see on the surface in the afternoon of today and tomorrow." ”

Yang Hao, who had regained his confidence, licked his face and asked Liu Yiyi, "Master, is there an easier way to do it in such a short time?"

"Simpler?"

Liu stared at Yang Hao with a smile and said, "Yes!"

"What is it?"

Yang Hao looked surprised.

Even Chen Song couldn't help but prick up his ears.

Liu Yan smiled and said word by word: "That's when you give up Xiangyu!"

These words exploded in the ears of the two like thunder.

Yang Hao's smile froze.

Chen Song looked up directly at the sky, as if there was something in the sky that strongly attracted him.

Yang Hao smiled and said, "Master, you are laughing again." ”

"Who is joking with you. ”

Liu Yiyan shouted with a serious face: "You think Xiangyu is very easy, you can't even visually inspect the distance of the surface cracks, how can you judge the distance between the internal cracks and the corners on the rough stone?

Yang Hao quibbled: "I mean, if there are any methods and skills, you can't just hold a ruler and keep measuring!"

"If you can know the distance accurately, you can measure it without a ruler!"

Liu Yan sneered: "Can you ask the question? Don't say that you are not familiar with this rough stone, and you can't recognize the length of the crack on it, it is estimated that you don't even know the length of each finger that you are extremely familiar with!"

"This ......"

Yang Hao was dumbfounded.

I wanted to refute it, but I didn't dare.

In this world, how many people can measure the specific length of each of their fingers and say it without hesitation?

Ten people are asked this question, and it is estimated that ten people will not be able to say it!

"I don't know what you look like, but since I don't know, measure it, and sometimes it can be used as a reference when it is compared at different positions from the eyes!"

Liu Yan snorted coldly, turned around and walked towards the small courtyard.

sighed secretly in his heart, hoping that the two could understand their hard work.

I once suffered a big loss at this distance to distinguish the rift!

This loss made him lose too many important things in his life.

"Thank you, master!"

"Thank you, Master Liu!"

Yang Hao and Chen Song bowed down in surprise and thanked them.

It wasn't until Liu Yiyan's figure disappeared that Chen Song comforted Yang Hao: "Master Liu is knife mouth, tofu heart, Brother Yang, don't take it to heart!"

"I know, master, he is also for my good, but sometimes I ask very white questions!"

Yang Hao sighed leisurely, and suddenly remembered that it seemed that he had been asking questions all along, and Chen Song had never asked many questions, so he couldn't help but ask curiously: "By the way, don't you have the same questions about the questions I usually ask my master?"

Chen Song replied without thinking: "Yes, how could there be!"

Yang Hao asked with some annoyance, "Then why haven't you taken the initiative to ask?"

Chen Song smiled: "Because I know you will ask!"

"Okay, you Chen Song!"

Yang Hao was so angry that his teeth itched.

Is this like human talk?

He is the one who benefits the most every time, but he is scolded every time he asks a question!

A hint of cunning flashed in Chen Song's eyes, and he said with a smile: "You are Master Liu's apprentice, you are the one who wants to learn Xiangyu, I am just listening!"

"Okay!"

Yang Hao was speechless for a moment, and looked at Chen Song with resentment.

What Chen Song said is not wrong at all, this is completely his own death hole, can he calm down like him and not ask?

Obviously, you can't do it yourself!

"Okay, Brother Yang, don't be angry, at most I'll ask more questions in the future!"

Chen Song felt a little hairy when Yang Hao looked at him.

"You said that!"

Yang Hao was overjoyed.

Chen Song replied with a serious face: "I said it!"

But there was a burst of laughter in my heart.

Asking more questions does not mean that you have to ask questions before Yang Hao.

When I was a child, I suffered a few years in this matter!

When the old man was teaching them when he was a child, because Chen Song was the youngest, he couldn't hold his breath and often asked some brain-dead questions, and every time he was used by the old man to open the brush, he was often scolded so bloody.

Later, he learned to be obedient, and saw that a few senior brothers and sisters didn't speak, and they didn't say anything, anyway, everyone encountered the same problem, and someone would always take the initiative to ask questions.

Slowly feel the benefits of silence, in addition to not being scolded, my temperament has also become calmer, and the most important thing is that after having a buffer time to think, I gradually learned to ask questions that can be asked to the point, try to avoid asking brain-dead questions, really ask some very white questions, and know how to organize the language that makes people feel not so white to ask questions.

Therefore, when you know that you don't understand, keep silent, listen more and talk less, and it is always correct to say more and lose, and you should focus on the key points when you speak, and you can't let people listen to it for a long time and still don't know what you know, and ask questions to be concise and to the point, so that you can get the information you want more effectively.

Thinking of the interesting things in the past, Chen Song shook his head with a smile and said, "Brother Yang, let's hurry up, otherwise we will be scolded again!"

"Hmm!"

At the moment, the two people took a tape measure, each found a rough stone, and used a tape measure to continuously measure the crack on the cutting surface, and from time to time got up to look at the crack at different angles to measure the distance, remember the length of the crack, and then measure the length and width of one of their fingers, and put the finger in front of the eye and compare the length of the crack.

I slowly found that as long as I fixed myself at an angle that suited my vision and clarity, by comparing the two, I could judge the true crack distance with a very small difference.

This discovery made Chen Song and Yang Hao excited!

I firmly believe that as long as I keep exercising, I can see the accuracy of the crack at a glance like Bu Sanbu Si.

Liu, who was secretly observing the two, smiled with relief when he saw the excitement of the two.

Outsiders think that Xiangyu Master is amazing, but in fact, to put it bluntly, it is just the result of hard work!

This visual cracks are difficult to say, easy to say.

You only need to practice for a long time, understand and be familiar with the real visual size of different cracks, and their visual sizes at different distances, and skillfully overlap impressions, you can know the exact distance, and if it is really difficult to judge, then directly use the known reference objects for comparison.

As for the references, their own fingers are enough!

Who doesn't touch the rough stone without touching it?

Compared with a ruler, the finger is nothing more than a lack of a scale!
