After Cheng Chumo heard it, the whole person was stunned.

He had indeed heard of this concept from Lu Heng.

But here's the problem......

Where's the difference?

Although everything here is inexplicable to Tubo, it is almost transparent to the imperial court, to Lu Heng, and even to His Majesty.

In this matter, the Cheng family only played the role of a bridge at most.

To make the difference, both parties have to know the inside story!

He said blankly:

"Dad, can you explain that?"

Cheng Yanjin shook his head with dissatisfaction.

"Silly son!"

"Since Lu Heng handed over this transaction to our family, he will definitely not let us work in vain."

"Although this Lu Hanzi doesn't speak very well, he does things as he wants......"

"But he's really nice to our family."

"If you think about it carefully, if it weren't for Xiao Yu's old thing to burn down the bookstore, if you do it for a few more years, you will definitely make a lot of money, and your reputation is still very good."

"He is willing to take our family with this kind of business, if it is an ordinary person, I am afraid that he will only do it with His Majesty and His Royal Highness the Prince, right?"

"Lu Heng, this stinky boy, still misses the old love."

"When you picked him up from the side of the official road and introduced him to the pharmacist, he had a chance to escape the oppression of the Zheng family."

"Could it be that if we let our old Cheng family make a little difference, what will he say more?"

"You ponder why he asked our family to put forward that condition."

"All the court wants is war horses, what does he want to do with cattle and sheep?"

"The purpose of saying it is to dispel the doubts of the Tibetan people."

"Actually, it's a big profit!"

Cheng Chu meditated for a long time, and finally figured out some taste.

He hesitated for a moment and asked:

"Dad, you mean, this allows the Tibetans to replace them with cattle and sheep when there are not enough horses, and the value of their cattle and sheep must be lower than the market price......"

"Is it Lu Heng's money-making door that Lu Heng specially left for our family?"

Cheng Yanjin smiled and nodded, his teeth looked extraordinarily white against the black face.

"Not bad!"

"For example, a sheep, how much can a sheep sell in Chang'an?"

"It's about the same for a few dollars!"

"Cattle are more expensive, but as far as I know, the cattle in Tubo are different from those in our Datang, they are the kind of cattle with extremely thick fur. There are also scalpers, but there will be much fewer of them. ”

"If you can't farm, it's worthless."

"They want to exchange this cow and sheep for wine, do you calculate, how much can a bottle of wine be exchanged?"

Cheng Chu silently counted his fingers for a long time.

He's really not very good at learning.

After a while, Cheng Chumo replied with some hesitation:

"The market price of Zhenguan in the spring of the tenth year is one hundred taels, which is one hundred yuan......

"Less than twenty sheep."

"Cows, about eight to ten."

Cheng Yanjin was not very satisfied.

He glared at his son:

"It's all said, the Tubo people want to exchange cattle and sheep, and the value of their cattle and sheep will be pushed down, how can you use the price of Chang'an to calculate?"

"The old man told you, when the time comes, you will have to negotiate the price, at least thirty or forty sheep for a bottle of wine!"

Cheng Chumo was stunned.

Own daddy......

This lion opened his mouth widely, and he opened it too hard!

He was just about to say something, but he saw the housekeeper come to pass the word.

"Master, the porter said that you had instructed before that if a Tubo man who claimed to be on the Qinling Tomb came to visit, he would communicate it to you directly, and there was no need to pay homage."

"Now the man is waiting at the door, you see......"

Cheng Bitingjin's eyes lit up.

He said happily:

"Coming so soon?"

"Moreover, he is alone!"

"Quick, bring him in, the old man wants to have a good chat with him!"

………………

The entrance of the Lu Guogong Mansion.

On Qinling was waiting outside, quite impatient.

He was afraid that he would not be able to see Cheng Yanjin himself today, so he would delay the matter.

After all, it's almost evening.

After a while, he will have to go back to the inn or he will run into curfew.

Fortunately.

It didn't take long for the porter, who had already known him, to finish the news and come back again.

"Let's go in, my lord happens to be in the house, count you lucky."

Although the gatekeeper did not have an attitude of contempt or anything like that, he also had a sense of arrogance that was very familiar to Qinling and the rich and noble families of the Tang Dynasty.

On Qinling, who has always been proud, has recently become accustomed to this kind of arrogance of the Tang people, and even feels a little happy about it.

After listening to what his father told him, his mentality has completely changed now.

What is the attitude of these subordinates in the Lu Guogong Mansion, which actually represents Cheng Yanjin's own attitude.

Cheng Yanjin attaches great importance to their business, but it is not good.

If he really pays attention to certain details, then he has to be careful not to have any problems.

And like now, even the attitude of the servants of the palace towards him is no different from that towards an ordinary foreign merchant......

Lu Guogong's heartlessness is even more certain!

On Qinling followed the porter into the door with joy, feeling that he had grown, and he was too mature than before.

After I go back, I must tell my father about my current mental journey.

He's going to be impressed with himself again!

"On ...... Oh, what are you talking about? ”

The porter turned around and called out to him.

"It's called the Tomb of Qin."

Although the other party didn't even remember his name, he was still not angry, and only smiled and said his name again.

The porter nodded and asked:

"The master said, if it is getting late today, it is time for you to come, and in a while there will be dinner at the house, just talk while eating."

"What do you have to fear? When the time comes, if there are any taboos on serving, I'm afraid the lord will punish me and other guests for neglecting them. ”

On Qinling was stunned.

He waved his hand and said:

"I won't stay for dinner, just talk about things and leave, it seems that the curfew is approaching, and if I stay any longer, I am afraid I will not be able to go back to the inn."

The porter was a little impatient, but seemed to try to restrain his temper.

"Master's order, it's one thing for you to stay or not, if I don't do it, then it will be me and others who will suffer."

"Is there anything taboo?"

There was really no way, so he had to briefly talk about his eating habits.

This time and again, he happened to follow him to the study.

After entering, he was a little surprised to find that in addition to Kai Cheng Biting Jin himself, there was a young man in the room who was younger than himself.

"It's better to come early than to come at a good time, haha, little brother, this meal will be ready soon, sit down!"

Cheng Yanjin greeted very hospitablely.

At this time, on Qinling is even more sure that this enthusiasm is Cheng Yanjin's character, and it does not mean that he attaches importance to himself.

Otherwise, according to the rules of the Tang people, he should call himself by his first name, not some little brother.

Estimated ......

This Lu Guogong is also the same as the porter just now, and he doesn't even remember his name.

Sure enough, I don't pay attention to it!

Regarding what Qin Ling is making up in his brain, Cheng Yanjin is naturally not clear.

He just casually introduced:

"This is a dog, Cheng Chumo."

"In the future, little brother, if you want to do business with my Cheng family, you will have to deal with him!"
