The thought-for-tat tension did not happen, and when Old Man Zheng arrived at Weng Shixian's courtyard, what he saw was a scene of three people talking and laughing around a small red clay stove.

Liu Yuhao also talked about the process of the old worker in the ancient method of jade carving, but when it came to the wear and tear of materials and equipment, Liu Yuhao and Mr. Weng had a disagreement.

Weng Shixian took a sip of tea slowly, and said: "The process of the old worker is naturally to pound stones, grind pulp, open jade, dig out the cup, flower on the flower, cut the jade, grind the jade, punch the eye, and glaze. Their common characteristics are that they use manpower and iron thallium, the rotation speed is not fast, and the jade is sharpened by jade sand, and the materials and equipment are worn at the same time. ”

Liu Yuhao smiled faintly, waved his hand, and said: "Mr. Weng, in fact, the so-called wear still depends on the craftsmanship of the carver, if it is controlled by manual positioning, the accuracy is poor, the geometric error is large, and there will be discrepancies in parallelism, datum, graphic symmetry, etc., but wear can be avoided." ”

Old Man Weng sneered and said: "The old worker medium is fine, the grinding amount is small, the processing strength is light, the cycle is long, and the jade pieces are not hot. The jade pieces carefully made by the old workers are very exquisite, the shape is symmetrical, the lines are smooth, the bore is wide, the ground is soft and flat, and the polishing is bright. ”

In fact, Liu Yuhao also knew that what Weng Shixian said had a certain truth, but from the "rich flowers", Liu Yuhao also combined with the secret record of the southern carving he got and found that many things are not static.

The old worker is indeed slow, but the victory is that the lines are relatively smooth, there is no collapse on the ditch edge on both sides of the line, and there is indeed no trace of waste material in the "rich flowers".

Because the bottom of the old ditch is frosted, there is no obvious long wear marks. This is because the thallium can only be ground when it comes into contact with the jade sand, and the jade sand is quickly taken away by the thallium wheel, which can only leave a short abrasion mark, and it is impossible to draw a long road, so Liu Yuhao judged whether the problem was here.

Later, Liu Yuhao really found in Haoyi Jewelry's jade carving factory that there will be long strip-like wear marks at the bottom of the ditch of the new worker's lines, because the sand particles on the grinding wheel cannot be arranged very evenly, and there are always individual sand particles that are slightly protruding, and the protruding sand particles will draw a long strip at the bottom of the ditch under high-speed rotation.

According to his own discoveries, Liu Yuhao made some subtle improvements to the jade carving machine, and added the special techniques of opening windows and forming holes mentioned in the jade carving machine in the secret record of southern carving.

Nowadays, Haoyi Jewelry's jade carving machine has taken the most advanced step in the wear and tear of jade, but these are all in the category of trade secrets, and Liu Yuhao can't say it in front of Weng Lao.

"Weng Shixian, you come out for me, what kind of ability do you have to detain a child?"

As he was talking, Old Man Zheng's angry voice came, which startled Dong Lao, who was originally drinking tea, and almost didn't squirt out a mouthful of water.

Old man Weng, who was still smiling and groaning just now, turned cold, put down the teacup in his hand, and said, "Brother Ciwu, you haven't come to me for twenty years, I didn't expect you to be so rude?" ”

Old man Zheng is rude? Weng Lao would actually say that the old man Zheng of the fairy wind and bones was rude? Liu Yuhao was stunned.

But looking back, Liu Yuhao was also happy.

The current old man Zheng is really a little rude, he doesn't say anything with an open heart, and he blows his beard and stare at his waist with a pair of hands, and yells at this room.

Weng Shixian and Dong Lao can take it big in front of Old Man Zheng, but Liu Yuhao doesn't dare.

"Grandpa Zheng, I'm really sorry for making you worry about me."

Liu Yuhao smiled very doggedly, helped Old Man Zheng into the house, and hurriedly brewed a cup of fragrant Pu'er tea.

Not to mention that the old man drove hundreds of kilometers for himself today to be supported by Liu Yuhao, even if he and Jiayi have to take the lead for himself and Jiayi in the future, how dare Liu Yuhao snub the old man.

Old Man Zheng saw that Liu Yuhao was completely covered in his body, and he didn't care about the ridicule in Weng Lao's words, and said happily: "Yuhao, I heard that you solved a 200-kilogram surge today?" ”

"Hehe, I can't hide anything from your old man."

Liu Yuhao smiled and scratched his head, which was an admission.

If you don't admit it, you can't do it, tomorrow the matter of solving Hetian jade in the jade trading market will be known all over the city, and I am afraid that anyone who plays Hetian jade will know.

Old Man Dong raised his eyes in astonishment and looked at Liu Yuhao blankly, and the tea in his hand was spilled, but he didn't know it.

Are you kidding?

You know, ten kilograms of mutton fat jade has been clearly positioned as a national treasure-level jade, two hundred kilograms? What does that have to be?

But Liu Yuhao's determined appearance doesn't seem to be lying, Old Man Dong is a little confused about this young man.

If it was purely due to luck, then the old man Weng had played Hetian Yu all his life, how could he be much stronger than a person who had just arrived, why didn't Weng Shixian gamble on the 200-kilogram rise?

Thinking of this, Old Man Dong moved his gaze to Old Weng.

"Hmph, the legend may not be true, you have to see it with your own eyes to know if it's true."

Weng Shixian was not surprised at all, in his opinion, solving two hundred kilograms of mutton fat jade was pure nonsense, and it was Liu Yuhao himself who put gold on his face.

As early as when it was not yet dark, Old Man Weng had already received the report, so he judged that Liu Yuhao must have solved the high-grade white jade, and even the green and white jade was possible, so he sat still and did not move at all.

If he knew that Liu Yuhao not only unraveled two hundred kilograms of mutton fat jade, but also left a back hand, hiding the really shocking Yushanzi and not unraveling it, he would not have fainted on the spot.

What kind of lucky people do you have to meet this!

Old Man Zheng was very dissatisfied with Weng Shixian's attitude, snorted coldly, and said, "Is it really your business?" ”

After speaking, Old Man Zheng felt that he had not yet shown his dissatisfaction with Weng Shixian, and spat on the ground again.

This amused Liu Yuhao, anyway, the two old men are already Taidou-style characters, how can they still play this kind of child's thing.

"Yu Hao, what about the mutton fat jade?" Old Man Zheng turned around and asked.

Liu Yuhao smiled and said, "It's in the car that General Hou came with you, old man, do you want to go and have a look now?" ”

This is not what Liu Yuhao wants to show, but a little cautious.

Now that it's dark, it seems a little impossible to store the mutton fat jade in the bank's safe, and Liu Yuhao is not at ease if he puts it in Hou Wanli.

It's okay to say in this courtyard, who knows if Hou Wanli will make any crazy moves out of this courtyard?

Now that there are two old men of the Jade King who know the whereabouts of the mutton fat jade, Liu Yuhao will naturally be able to reduce the risk and pressure, even if any old man doesn't speak, Hou Wanli may not have the courage to swallow that piece of jade.

"Let's go, let me, a bad old man, go and see what the 200-kilogram surge looks like."

Old Man Zheng patted Liu Yuhao's shoulder, his eyes were mixed with a hint of excitement, and he didn't care at all that Weng Lao was glaring at him angrily.

Weng Shixian's eyes faintly spewed out a trace of anger, and his eyes stared at Zheng Lao Dao with a glittering gaze: "Zheng Ciwu, you are too much, where are you and my Weng family, come and leave as you want?" ”

Old Man Zheng pursed his lips disdainfully and said, "No one said that they wouldn't let you come with you, why are you in a hurry?" ”

"You" Old Man Weng bit his cheek hard, temporarily suppressing the anger in his heart.

The two of them have been fighting since they were teenagers, so everyone is familiar with each other's temperament, otherwise, Old Man Weng would definitely not show that angry look with the respect of the head of the Weng family.

Although Old Man Dong's hobby for Hetian jade is only in the nature of playing tickets, when he heard that there were two hundred kilograms of mutton fat jade, he couldn't bear it in his heart, so he got up and followed.

When the three old and one young came out of the courtyard, Weng Xueyan was standing at the door with a restless expression.

When she saw Liu Yuhao come out with a smile, and Zheng Lao was also calm, he breathed a sigh of relief in his heart, stretched out his white little hand and patted his full breasts, and suddenly there was a turbulent wave.

"Ahem, cough, cough"

Liu Yuhao coughed violently at first, and then glanced at Old Man Zheng who was staring ahead.

Fortunately, Zheng Lao's face was indifferent, and he didn't notice Liu Yuhao's abnormal behavior.

Only then did Liu Yuhao free his hand to wipe the sweat on his forehead, and said in his heart: "What a big killer!" It's really a killer, and it's so tough before you get married, and you can pay it back when you get married in the future? ”

When the private person walked to a corner, Old Man Zheng suddenly glared at Liu Yuhao coldly, and said, "Stinky boy, you also want to make up your mind about the little girl of the Weng family?" Save you! ”

"Uh, old man, I didn't do anything!"

Liu Yuhao's face was swollen and red, but he didn't admit what he was thinking just now.

"Humph! Do you know it in your own heart, I'm just giving you a heads-up. ”

Old Man Zheng found that the people behind him were following, so he just said something in a very low voice, and then walked away with his head held high.

Liu Yuhao was embarrassed, but he would never admit it when it came to this kind of thing.

Are you stupid for all those old men? People are pretending to be confused with their eyes open!

But what they think in their hearts is one thing, classmate Liu will not sell himself before he is sentenced.

"This is really sheep fat jade, old man Weng hurry up!"

Old Man Dong was the first to see the piece of mutton fat jade, when the fair, flawless, oily, delicate and creamy mutton fat jade appeared in front of him, Dong Lao's eyes widened in horror at first, and then he waved his hand vigorously to greet Old Man Weng.

Dong Lao is an expert in medical skills, but Dong Lao is still willing to be inferior to others in terms of jade attainments, and only when Weng Shixian says that he will truly agree with it in his heart.
