Xia Yanqing saw that Tang Da and the others understood, and continued to flicker: "So, you adults can't use the carriage and this ......" She pushed the bearing on the table in front of her, "You can't measure the value of the bearing by what material it is made of." Your Excellency, you have to think so, once the four-wheeled bearing carriage enters the transportation system of the imperial court, how much will the transportation efficiency be improved? How much manpower and material resources will be saved in a year? Especially when there is a shortage of materials or armaments, the transport team can arrive a day earlier and deliver more, which may be able to reverse the predicament......"

She said this Balabala, and several officials were stunned.

Tang Da was so dizzy that he almost nodded in agreement, and suddenly remembered the bottom line of the three thousand taels of silver that Liu Wu explained, so he stopped the nodding action, and it flashed very much.

It's dangerous! He wiped his sweat. The aunt and grandmother of the Xia family opened their mouths, which was 20,000 silver, and threatened that this was already a friendship price and would not accept counteroffers.

I can't listen to her anymore, and after a while, he accidentally nodded and agreed, who is he looking for the extra 17,000 taels of silver?

"No way!" Tang Da shook his head decisively, "Three thousand taels of silver is enough, your bearing production is not a secret, and now many people outside Qingyun Zhai know about it." After a while, if it is looked at by ordinary craftsmen, and people make their own carriages to sell, Qingyunzhai is afraid that they will not be able to get a tael of silver. ”

"Master Tang," Xia Yanqing said bitterly, "what you said is not right. In addition to the craftsmen of Qingyun Zhai, only the adults and masters who will be the supervisors know the bearings and the bearing method. We are the people of the Great Liang Dynasty, so we do not avoid Master Qu and several masters. My lord, you use this as a reason for a big bargain, isn't it? ”

Tang Da has come back to his senses, and he will not be dizzy anymore, and his attitude is even more resolute: "The official has raised the reserve price of one thousand taels to three thousand taels, which is already the extreme, and there is no more than one penny." ”

Xia Yanqing looked at these officials with great distress, are these guys too dead-eyed? Or did the court set a bottom line for them?

Twenty thousand taels is a bit much, this is her asking price, there is moisture. The reason why she never let go was because the price given by Tangda was too low. Three thousand taels of silver, it's a little less, she really can't bargain.

Thinking so, she turned her gaze to Qu Jiang, and he was still holding the bearing model standard she had written.

It just so happened that Qu Jiang had finished reading a few pages in a hurry, and there were many doubts waiting to be asked in his heart.

Those written earlier: In order to enhance the versatility of the bearing, the specifications and models of the girder towards the bearing were formulated by the imperial court. In the future, whether it is a private or public workshop, it is never allowed to have bearing specifications beyond the standards of the imperial court.

Qu Jiang understands all this, and he also understands the ball bearings mentioned next. But then those standard models represent: What is a cylindrical bearing? And needle roller bearings, thrust bearings, eccentric bearings, etc., what are they?

"Miss Xia, haven't we seen the others you mentioned here? Like this, what is an eccentric bearing? What is the eccentricity? Qu Jiang asked, pointing somewhere on the page.

Xia Yanqing took the stack of documents with his hand, and explained very casually: "It's just eccentric." I wondered if there might be a different way of turning. If you can make a bearing that is not centered, when one shaft rotates, you can drive another axis that is not centered to rotate, and that should be called an eccentric bearing. ”

"Two different spins......" Qu Jiang looked at the two officials he brought, and the two officials were nodding at him and the chickens pecking rice.

The two craftsmen in the Ministry of Industry also wanted to nod, but they didn't know who to target. They also saw that document just now, which involves many types of annotation methods, what if they don't remember those types? What if you don't understand what those types refer to?

Just listening to the eccentric bearing explained by the owner of Qing Yunzhai is very stunning. If someone gives them the materials and the time to develop it in this direction, they can't say that they can also invent a component.

It's a pity that they just took a rough look. I went out of Qingyun Zhai today, and I want to come in again in the future, and I want to ask about this kind of thing...... There's no chance. It's true that people are doing business and doing craftsmanship, but they are also the daughters of four-grade officials, and they have a strong fiancé, where can they ordinary craftsmen meet and talk?

Qu Jiang didn't think much about it, but was excited: "Yes, yes, there are really such moving parts," he stretched out his hand to get the document back, his mouth kept talking, and he continued to ask, "What about the thrust bearing?" And what do you mean by double layers and double columns? ”

But seeing Xia Yanqing's hand shrink, he simply took back the document and handed it back to Qiluo, "Take it back, let the heart be put away, and put it back in its place." ”

Qu Jiang was immediately stunned, and his hand subconsciously stretched out in the direction of Qiluo. How could the little girl only agree to her master's instructions, leave a back, and after walking a few steps, she opened the door and went out.

"This, this, Miss Xia, didn't you say that this document would be attached to the imperial court? Why did you take it again? Qu Jiang was in a hurry. Where is this what Xia Yanqing said before to write casually? This is really a technical document, and there is a lot of content involved!

Xia Yanqing was not frustrated at all because the negotiation with Tang Da did not go well, he was very relaxed, and replied to Qu Jiang with a smile: "Master Qu, you also said that it is a gift, and the deal is completed, so it is called a gift." If the deal fails, it's called giving it away for nothing. I am a businessman, how can there be a reason to give away things for nothing. ”

"......" Qu Jiang was immediately speechless.

Several insiders, including Qu Jiang, all looked at Tang Da, the kind of condemnation in their eyes, the kind of hatred in their expressions, as if Tang Da had committed a heinous crime.

Tang Da was stunned by a few people, and there was a third-grade senior who also condemned him here, would he report his unfavorable affairs to the emperor?

But he can't be blamed for this, Master Shangshu gave a maximum of 3,000 taels of silver, how dare he promise an extra 17,000 taels?

"Master Qu, Xia Guan can only be the master of three thousand taels of silver, there is really no way." Tang Da spread his hands and explained to Qu Jiang.

Qu Jiang was so annoyed that his beard trembled, and he only gave three thousand taels, he reminded Liu Wu in vain yesterday!

Even if Liu Wu feels that 10,000 taels is a bit much, then it is not good to directly fight seventy percent, right? In this way, he just wants to come forward to make peace, and there is no room for it!

It's just that the emperor handed over this matter to the household, and he really didn't want to say anything.

Why was he in such a hurry to ask for that document? After the matter is discussed, Xia Yanqing will definitely not break his promise, maybe he doesn't need to replace him, and the girl will give it to him.

Now it's okay, the matter hasn't been discussed, but he has seen it, and his heart is itching, okay?

The two craftsmen of the Ministry of Industry also scratched their ears and cheeks, hating that they didn't memorize the content they couldn't understand, even if they couldn't memorize all of them, it would be good to memorize those few keywords.
