"Lu Xianggong ......" Zhao Xin suddenly asked: "There is a lonely matter, I want to ask Xianggong ......" "The king is serious, but if he asks, the minister knows everything and says everything!" Lu Yijian immediately bowed down.

"What is the origin of the country's entry into China today?" Zhao Xin asked softly.

It is a government-run economic and trade system created and unique by the Northern Song Dynasty.

This trading system is somewhat similar to the futures of later generations.

But it is different, futures are designated commodities, designated delivery dates, and marked prices.

However, as long as it is delivered to the area where it is allowed, you can get a reward - an officially issued paid security.

Then the businessman took the securities to Bianjing and settled with Zhao Guan's family.

The settlement method is not to give money directly.

Instead, it is converted into hard currency such as tea, salt, spices, silver, and gold in accordance with the prescribed proportions.

This process is known as folding.

Generally speaking, in order to encourage businessmen to enter the middle school, the state will often use high premiums to encourage businessmen to actively enter the middle school.

According to the distance and criticality of the entry location, the conversion method of the entry goods is also very different.

Like now, the premium rate of grain entry in the border military states is as high as seven times!

In other words, as long as 10,000 guan worth of grain can be sent to the border, 70,000 guan of salt, tea, cloth, spices, silver, gold, and other hard currencies can be cashed in Bianjing.

Of course, it's also something that looks beautiful.

In fact, the water of trade with China is very deep.

In Zhao Xin's previous life, when he changed the law, Wang Anshi said: Xiao Jia can't enter the middle school, only Da Jia can! Only the big ones can! Therefore, the power of the border is controlled by Dajia, so the price is high and the official fee is heavy.

In fact, what Wang Anshi said was very polite.

In fact, the names of these great men are relatives, clansmen, and important ministers.

Bianjing City's Jieshen Lane, walk in and take a look, the magnificent, the façade is vast, the house is majestic, the look is forested, and who is the owner of the shop that is tens of millions of dollars per transaction?

You can turn it out when you go to Kaifeng Mansion.

Now, it is definitely either surnamed Cao or Zhao, and there may be someone surnamed Lu.

Each of these shops, with a monthly throughput of less than 500,000 yuan in securities trade, can go home to wash and sleep.

Of course, the water in the middle is so deep, Zhao Xin will not move now.

Instead, he will turn a blind eye and hear but not hear.

He just wanted to take advantage of the peculiarities of trade with China to do something for himself.

Where did Lu Yijian know this, when he heard it, he was startled, but he still answered honestly: "Back to the king, now the main purchase is salt, tea, spices, silver, gold, silk cloth, silk ......."

"What is the designated product?" Zhao Xin thought about it and asked again.

"It should be grain, wood, feathers, anointing oil, etc., ......"

"Add a ...... to the middle school book," Zhao Xin commanded softly.

"What?"

Zhao Xin smiled and said, "Dried fish!" Dried sea fish! ”

Lu Yijian raised his head for some reason, when will Da Song have a large supply of dried sea fish? Who are these things sold to?

However, he didn't ask much, anyway, he added a new product to the middle school.

It's just a matter of raising your hands.

Whether the merchants want it or not, that's the businessmen's own business.

Anyway, Lu Yijian is very clear, what I said in the middle of the test, I am willing, forcing the cow's head to drink water, Taizong and Zhenzong have done it, and the result is ...... The trade between China and China has fallen sharply, and the side is insufficient, so it can only be stopped.

Since then, the Zhao family has given up interfering in trade with China, and has begun to adhere to the market economy, leaving everything to the invisible hand of the market.

If the use is sufficient, the premium rate will be reduced, and the premium rate will be increased when the use is exhausted.

The market has the final say!

As a result, trade between China flourished, and in the past few decades, countless people have been fed in Bianjing.

"In addition, there is one more ...... in the middle of the materials. Saltpeter, nitrate powder ......" Zhao Xin chuckled: "The merchant has arrived in Beijing, and after the delivery, please count it immediately!" ”

Saltpeter and nitrate powder will inevitably become strategic materials in the future.

After all, if you only rely on the construction of the project to do it yourself, or set up a state-run nitrate powder production organization.

Then I am afraid that not only will it cost a lot and waste a lot, but it is also likely to breed all kinds of problems.

It is better to hand it over to the people at the beginning, and let the powerful businessmen help collect and produce.

In this way, the supply and reserves of potassium nitrate obtained by Da Song will be greatly increased.

As for the leaks......

To be honest, as long as black powder is used, it is difficult to guarantee that it will not be leaked.

Because after the start of the war, it is impossible to avoid the soldiers who use their own weapons of black powder from being captured by the enemy.

Once the enemy gets the firearms of the Song soldiers, then even if they can't copy the original firearms, it is still very simple to copy a firearm with six or seven percent of the power.

Therefore, if you want to maintain your advantage, the key is to rely on yourself.

As long as your own industrial level is strong, the speed of riot soldiers and equipment is fast enough.

Then the enemy will not be able to catch up with the horse.

Especially, for the current world.

The level of technology and handicrafts of the Great Song Dynasty is top-notch.

Lu Yijian listened to it, and immediately remembered, it seems that the thunderbolt made by His Royal Highness the Tang King a few days ago will use a lot of nitrate.

Now, it's not surprising that he's adding a piece of nitrate to the middle.

Moreover, he thought about it carefully, this kind of thing is not worth alarming the official family.

After all, Tang Wang only added one material and one book to enter China.

The rest is the businessmen's business.

The merchants felt that it was profitable and were willing to exchange the entry tickets in their hands for dried fish, or they were willing to travel thousands of miles to transport a truckload of nitrate powder to Bianjing.

It's all their freedom.

It's all started when they feel that they have something to earn.

So, Lu Yijian bowed his head and said, "The ministers will arrange for someone to do this well!" ”

It's just a matter of writing a post and the next official document, and it doesn't take much effort.

As Lu Yijian himself said, it's just a matter of raising his hands.

Zhao Xin listened, smiling.

He originally thought that he would have to spend some words to persuade Lu Yijian to agree.

Now it seems that Lu Yijian is afraid that he will be overwhelmed by Zhao Zhen's fainting on the woman's belly, and he is unwilling to compete with himself in these details.

"I'm a genius!" Thinking of dried fish, Zhao Xin licked his tongue.

In later generations, there is a place called Station B, where a group of celebrities are active in catching the sea.

Before the crossing, Zhao Xin watched the video of these people catching up with the sea.

And in the sea world, there is a kind of fish, known as the golden legend, the fortune fish - cucumber fish, that is, wild big yellow croaker.

Legend has it that if it is more than a catty, its value has soared sharply, and the price is denominated in two.

And this kind of fish, once flooded, coastal areas, I don't know how many, every year will form a huge yellow croaker fishing flood.

How did it get it?

The answer is that the hard-working, brave and intelligent Zhejiang fishermen invented a fishing method called knocking operation, using the physiological weakness of the yellow croaker belonging to the totoaba fish, using a large number of small fishing boats to form an encirclement to surround the yellow croaker group, and then knocking on the bamboo pole tied to the small fishing boat, using sound waves, the otolith used to balance the yellow croaker ear to shatter.

As a result, the fish loses its balance and is left to the slaughter.

Xia Shouyun went to Guangzhou to do this.

Last month, Xia Shouyun had already replied to the letter, in the coastal area of Quang Nam, organized fishermen, to fish by knocking out the method of fishing, and sure enough, the effect was remarkable, just one May, just more than 800 small boats plus more than a dozen large boats, more than 4 million catties of fresh fish, after drying to get nearly 10,000 stone of dried fish.

And it only cost more than 30,000 pieces of labor.

It's a big deal!

Now, Xia Shouyun is ordering his cronies to take the army to escort this batch of dried fish with a total of nearly 10,000 stones, starting from Guangzhou, day and night, to send them to Bianjing.

In the future, every month, Guangnan East Road will escort at least 10,000 dried stone fish to Bianjing!

Needless to say, these dried fish came at the right time!

Especially at this time, the arrival of these dried fish in Beijing will once again strengthen and deepen the aura on Zhao Xin's body!

Lu Yijian didn't know about this, because Xia Shouyun was a retainer of the Zhao family, and his report would not go through the Chinese book, but directly in the way of beeswax, and went straight to the king.

One was sent to Zhao Zhen's case, and one was sent to Zhao Xin.

In other words, apart from Zhao Zhen, the only person who knows about this matter is Zhao Xin.
