Bi Gou heard the end from the beginning, holding the glass, looking at Li Yi in a daze, without saying a word.

He understood, when Datang did not cut off the Silk Road on the land route, he used technology to exchange things with the Western Regions.

Silk, tea, in exchange for precious things.

After listening to Li Yi's explanation, he understood that this is called system theory, and summarized it.

It is countless times stronger than simply thinking that your own things are good and others need them.

Bi Gou knew why this was the case, where the extra money came from, it turned out to be the added value of technology.

After a long while, Li Yi's side began to refill the water, and Bi Gou spoke up: "Our Datang has been taking advantage? ”

"Not necessarily." Li Yi waved his hand: "In addition to the added value of technology, there is also labor cost, and it is different for the villagers to work for an hour and the people to do it for an hour." ”

Li Yi began to talk about the labor cost for Bi Gou again, and the people of the Tang Dynasty worked for a day, with a salary of 30 yuan.

The people of the Japanese Kingdom worked for a day, which was equivalent to the salary of five coins in the Tang Dynasty.

The people of the Wa Kingdom did not pay compensation, and the court of the Wa Kingdom did not pay either.

They got the Datang goods they needed, and they paid the normal cost of labor.

The quality of the iron tools of the Tang Dynasty is better than that of the Wa Kingdom, and after the Wa Kingdom purchases them, they are used to make labor tools and improve labor efficiency.

The people of Datang cut pigweed to feed pigs, and raised chickens in the mountains to eat, and when they were sold, it was a price, plus labor costs.

At the cost of manpower, the Japanese also fed pigs and chickens, and sent pigs and chickens to Datang to sell, and obtained good things to make up for the loss of the trade deficit.

The purchasing power of the copper coins in the country is not as much as that of the things bought in the Tang Dynasty, as long as the Japanese are willing to bear the loss of mineral resources, they still make money.

"Is it that complicated?" Bi Gou put down the cup and rubbed his face with his hands.

He felt that he had lived for decades in vain, and he was the assistant of Zaifu, and Li Yi would play everything he could.

Li Yi played something, and he was dumbfounded when he heard it.

thought that he was a chess player as the prime minister, but Li Yi used the world as a chessboard in the layout.

"It's simple, but it's more complicated. In the later stage, it can transfer the domestic economic pressure of Datang. ”

Li Yi shook his head, where is this, let's learn.

Bi Gou looked at the monk fruit floating on the water: "Through such trade, the biggest gain is low-cost products. ”

"No, the greatest gain through trade with the Wa Kingdom is to teach merchants to go to more places to obtain resources."

Li Yi put the affairs with the Japanese state in a secondary position, and it was important to cultivate maritime trade talents.

Bi Gou rubbed his temples: "The old man won't ask first, I can't remember, I have a headache." Give me a copy of it. ”

Bi Gou's later words were saying to the palace maids and eunuchs, and the palace maids and eunuchs were recording.

After the record is finished, a person makes a copy of what he wrote and puts it together for Bi Gou.

And it would have been pasted and sent to Li Longji, and Li Longji needed to learn.

After the transcription was completed, Bi Gou did not plan to eat at Zhuangzi.

He took two thermos with him, saying that they were for his two younger sisters, who did not live with him and did not have thermos at home.

"Old Bi, don't you want a kerosene lamp?" Li Yi chased and asked.

"I'm sorry to take too much at once, wait for the next time." Bi Gou dangled out with a thermos in one hand.

"Why didn't I feel embarrassed about you?" Li Yimu sent Bi Gou away and muttered.

"The proprietor, the main reason is that it is inconvenient to take it, and he didn't come in with his attendant." Cuiliu said next to him.

"Be careful, he hears the accusation against you." Li Yi smiled.

"He can't control me, so I'm not afraid." Cuiliu stuck out her tongue, looking like she had a backer.

Bi Gou crossed the bridge here, got in the car and went back to the political hall.

"Fill me with hot water from the two thermoses, plug the thermos corks, see if there is a gas leak, if there is a gas leak, then go to Li's Zhuangzi to ask for a new thermos cork."

Bi Wei pointed to the two thermos and instructed his subordinates that there was no problem with the pot gall, and the problematic pot could not get out of the 'factory'.

The cost of the pot is fixed, and the shell outside the thermos is made of different materials.

Some also use good wood and then inlay jade.

The thermos of Lijia Zhuangzi is woven with bamboo strips, and if it accidentally falls to the ground, the bamboo has a buffer and is not easy to break.

"How, do you collect taxes or not?" Song Jing and Su Ying went to Bi Gou's office together.

"If you don't accept it, you don't have much of it, but you can help the Japanese country and make their currency circulate......"

Bi Gou told the two that the Li family Zhuangzi helped print currency and trade in the Tang Dynasty's commodities.

He did not say that the method of letting the Japanese state replace it with copper coins at half price in terms of peace and reconciliation, this method is good, but it will help the Japanese currency to circulate in its own country.

If you are not related to you, why should you help the Japanese country? It's not good for Datang.

Song Jing and the others also had a headache, what added value, labor costs, trade structure, surplus and deficit balance......

The only thing I know is that according to Li Yi's method, Datang can take advantage.

When Li Yi faced the people of the Tang Dynasty, he could suffer by himself. In the face of other countries or tribes, Datang cannot suffer.

It has already been decided, internally, Li Yi is willing to endure, and externally Li Yi is very tough.

"Find an opportunity to reveal a little bit to the envoys of the Japanese Kingdom, and ask them to take the initiative to come to the door, otherwise they will be suspicious."

Song Jing also learned from Li Yi externally, but he was not good externally in history, for fear that the Tang Dynasty soldiers would take the initiative to attack and cause trouble.

Now he is even more afraid of joining the group, and he has realized that as long as he adopts a retreat policy, Li Yi can get himself into the group.

Datang is not the prime minister, and all the prime ministers must act according to Li Yi's will.

Su Ying spoke up beside him: "I heard Your Majesty say that the envoy of the Japanese Kingdom made Princess Yongmu uneasy, and Princess Yongmu wrote a letter to Li Yi.

said that it was the Japanese delegation to Dongshi, and when she looked at her, she felt that the other party was covetous, and the idea was like this, can they stop thinking that they shouldn't have?

Because there are many people, the other party looks very imposing, and it is estimated that it is because of this that the other party will have other ideas.

If you hide quickly and don't come out, will there be no problems and you can live in peace?

Princess Yongmu looked very aggrieved, and it was estimated that the envoys of the Japanese Kingdom would be unlucky. ”

Su Ying said what Li Longji told him, and Li Longji was angry, looking at his daughter.

Su Ying laughed out loud, he didn't think that Princess Yongmu would be in danger, Li Yi was famous for protecting calves.

Once Song De was bullied, how did Li Yi fight back, and he cleaned up the shopkeeper Liang and them at one time.

Where to start and where to end, it's so domineering.

"I hope no one dies." Song Jing was afraid that Li Yi would kill people.

Killing the envoys of the Japanese state is killing without evidence, what do others think?

Bi Gou has a say in this: "It is impossible for Xiao Yi to kill people, the envoys of Tibet and Turks, he is just scared, not killed."

The two countries are at war, and they do not come to the enemy. What's more, when the Wa Kingdom is not at war with my Tang Dynasty now, Xiao Yi knows how to measure. ”
