The price is set, and then it's the way of delivery and transaction.

Su Baiyi was more casual at this point, because he had a large ship for easy transportation and enough silver to buy.

Nguyen Phuc Lan made two demands.

First, the cash silver is delivered, they do not accept copper coins, and they want enough silver and good fineness.

Su Baiyi naturally has no opinion on this.

But the second point came as a surprise to him.

Nguyen Phuc Lan proposed that the transaction must be carried out in the form of the state, which is a trade between the Ming Dynasty and Quang Nam State, and the people of the Ming Dynasty are not allowed to go to the private sector to buy grain, and these grains are under the responsibility of the Quang Nam State government.

It is not for nothing that the Nguyen clan was able to stand tall in the south of the Yangtze River for hundreds of years, and eventually unified the entire territory of Vietnam, swallowing the Cham and Chin La Khmer regions. There is no fool in the family, although this Ruan Fulan looks fat like a pig, he is very flexible and not stupid at all.

In this way, by direct official transactions, first, the amount of grain exported by the country can be controlled every year, and the province will be bought out by the Ming Dynasty; Second, Ruan Fulan profoundly knows that the rice in the Quang Nam area is one tael of silver and four stones, which is near Fuchun, and the further south it is, the cheaper it is, if the Ming envoy goes directly to the south to buy, the profits will fall into the hands of the Ming Dynasty; Another point is that the frequent contact between the Ming envoys and the people of Quang Nam is not a good thing.

"Yes, this envoy can be the master and agree!" Su Baiyi actually didn't really have the heart to plot against Annan, he just wanted profit, so although he might be slaughtered by Lord Ruan by taking the opportunity, he was also convenient, wasn't it?

You don't have to buy rice from all over Quang Nam piecemeal, saving time and effort!

In this way, the matter of rice is decided.

And then there's the second big business: rubber!

Nguyen Phuc Lan had heard the name 'rubber' more than a hundred times, but until now, he didn't understand what rubber was. Therefore, for rubber, he is unusually solemn.

"Dare to ask the envoy, the widow has never heard of rubber, what is it and what is it used for?" Ruan Fulan asked suspiciously.

Su Baiyi naturally wouldn't hide it, so he opened his mouth and said the basic knowledge of rubber: "Don't worry, the king doesn't have to worry about it, rubber is a kind of tree, this kind of tree has a heat-loving temperament and is not cold-tolerant, and I can't plant it in the Ming Dynasty, so I came to your country to trade." This tree is very easy to grow, just plant it in the mountains, and after four or five years, the small saplings can grow into big trees, and when the trees grow, you can tap rubber! ”

"Tapping?" Ruan Fulan looked confused: "Is it cutting down rubber trees?" ”

"Definitely!" Su Baiyi said: "The bark of the tree was cut with a sharp tool, and milky white sap flowed out of the stem, and the farmers collected it with a bucket, which is rubber." ”

"Oh......" Ruan Fulan roughly understood.

All things are born in heaven and earth, each with its own temperament, just like the poppy, cut a knife mark on the unripe fruit shell, and there is juice flowing down the knife mark, these juices are an excellent condiment, and a precious herb.

Nguyen Phuc Lan felt that this rubber tree should be similar to the poppy.

"If it is planted on the mountains and does not encroach on the farmland, this king will not object to it!" As Ruan Fulan spoke, his brows furrowed slightly, and he said flatly: "Can the envoy tell me, what is the purpose of this tree sap?" ”

Su Baiyi did not hide it, and said: "The sap cut from the rubber tree can be obtained from natural rubber after drying and preliminary processing. As he spoke, he took out a pair of slippers made of natural rubber from his arms, and put them in front of Ruan Fulan and said, "The king can try it, this is a shoe made of rubber." ”

Ruan Fulan didn't raise his feet, but just touched them with his hand, and said with a smile: "It's quite soft." ”

"Yes, King!" Su Baiyi explained with a smile: "Rubber has many excellent properties, such as soft and elastic, in addition to this property, it is also waterproof, so this kind of shoes, the king can wear a bath, and after the bath, blow a little in the tuyere, and it will be dry." ”

As he spoke, Su Baiyi poured a cup of tea on his rubber slippers, and after the tea soaked for a while, he wiped off the water stains with the towel in his hand, handed it to Ruan Fulan again, and said, "King, please see, is it already dry?" ”

"Well, indeed!" Nguyen Phuc Lan did not show a different color.

Because there are many impermeable things in this world, such as steel, such as painted items, and all kinds of metal products.

"If you let us grow rubber, is it just to make this kind of shoes?"

"Of course not!" Su Baiyi said with a smile: "Rubber has many uses, because it is soft and elastic, so it can be made into a buffer block and installed in front of a large ship, and the ship will neither damage the dock nor the hull itself when it docks." Wrapping this object around the wheels of a cart can also alleviate the pain of bumps; Because it is impermeable, it can be made into thin sheets to make clothes, commonly known as raincoats, and can be worn on the body when it rains to protect against rain; It can be made into waterproof gloves; You can use it to wrap the handle of your sword, reduce damage to your soldier's hand, and more! ”

Ruan Fulan's eyes flashed with a gleam, and he said, "It turns out that there are so many benefits? ”

"Of course, if there weren't many uses, the envoy wouldn't have traveled all the way to do this." Su Baiyi looked at Ruan Fulan, naturally knowing what he was planning in his heart. From rubber juice to rubber products, the process in the middle is not as simple as you think, and there are many auxiliary items used to the sky, you want to produce it yourself, hehe, welcome to the pit.

"Then the price ......" Ruan Fulan's small eyes narrowed.

"Dry glue, equivalent to grain!" Su Baiyi said with a smile.

After the rubber tree is planted, it will take five or six years to be able to tap the rubber, and the rubber trees carefully cared for in the 21st century in the future will have a yield of about 30 catties per tree, and 35 trees will be planted on an acre, and the yield per mu will be about 1,000 catties.

In this way, one acre of land is about the same as grain, and it is also four stones.

So, he gave a price equivalent to the grain.

Although this rubber tree grows in the mountains without a lot of difficulty, there is one thing that is extremely troublesome, and that is rubber tapping. The tree tapping rubber has to be cut once every two or three days, and the collected juice also needs to be solidified and dried before the dry natural rubber raw material can be obtained. Therefore, it is extremely laborious, and the rubber is toxic, so the price cannot be considered high.

The point is that after the rubber is planted, there is a five-year vacuum period.

In the past five years, I have to take care of the growth of rubber seedlings, but I can't tap the rubber.

Ruan Fulan asked cautiously: "I don't know what the output of this dry glue is?" ”

Su Baiyi said with a smile: "If you take care of it properly, its yield will be comparable to that of your rice in Guangnan Kingdom!" ”

"This ......"

Ruan Fulan's pupils shrank slightly.

What is the concept that it can be grown in the mountains and at the same price as rice?

Annan is known as the saying that there are seven mountains, two rivers and one field.

Quang Nam is not even as good as the Trần clan in the north, and Nguyen Phuc clan's territory is basically 80 percent covered by mountains, and if these mountains can be developed to grow rubber trees, then ......

If you call on the whole country to plant this rubber, buy it at a low price and sell it at a high price, this is 10,000 times stronger than taxes.

Ruan Fulan's heart instantly became hot.

"Lord Angel!" Ruan Fulan's voice was full of excitement, and he looked at Su Baiyi and said with a smile: "I don't know how many stones your country can buy this kind of rubber every year?" ”

"Hehe, this thing is just for use, not for eating, so we don't need that much, we can only buy 500,000 stones a year."

"So little?" Ruan Fulan's egg hurt.

500,000 stones are only 100,000 taels of silver, although it is good, but it is a little too chicken.

"Can you have more?" Ruan Fulan looked at Su Baiyi pleadingly.

Su Baiyi smiled bitterly: "This thing can't be eaten, it will take half a year for me to make a pair of shoes to wear out, and it's really useless to have more." He was telling the truth.

500,000 stone per year, equivalent to 30,000 tons.

If it is a large industrialized country, it can eat even 30 million tons, let alone 30 million tons. But his industrial base has not yet been fully developed, and this 30,000 tons of rubber per year is already the limit.

"My lord, if you can buy two million stones a year, the owner, oh no, the widow is willing to add another two million stones of grain." Ruan Fulan gritted his teeth and said.

Su Baiyi frowned.

But after all, he couldn't resist the temptation of the two million stone grain, and nodded in agreement: "That's okay, the king really gave the minister a big problem, these things can't be used up, and I don't know if the manufactured things are good to sell, but in this case, the minister has another request." ”

"You say!" Ruan Fulan said briskly.

"The foreign minister's request is very simple, if rubber products are made in the future, and the foreign minister wants to sell them in Quang Nam, the king will reduce or reduce the customs duties." Su Baiyi smiled bitterly.

Ruan Fulan thought about it solemnly, and said painfully: "I'm afraid this is unreasonable." ”

"If it weren't for that, the foreign minister would rather die than buy two million stones."

"Okay!" Nguyen Phuc Lan waved his hand.

What is the tariff, to put it bluntly, it is additional, the wool is out of the sheep, and when the time comes to sell the goods, the price will be increased, anyway, the transaction party with the Ming Dynasty is the official Guangnan official, not the common people.

"Thank you, Your Majesty!" Su Baiyi reluctantly accepted it.

The industrial establishment he planned was extremely large, and rubber was an indispensable industrial product, with countless other uses besides raincoats, slippers, and cushioning equipment.

The first is the tires, which goes without saying. Nowadays, the family has been able to produce chains and bearings, and now with rubber, you can produce bicycle tires, and in later generations, the kind of bicycle inner tubes that cost eight yuan a piece are pure natural rubber products. In addition to bicycles, in a few years the internal combustion engine should also be available, and then there will be tractors, and the tires of those tractors will also cost a lot of money.

The rest are wires, hoses of all kinds, and hard pipes, which are essential items in industrial development.

It doesn't matter if you can't use it up now, just keep it for now, there will always be a time when you can use it up in the future.

Moreover, the growth cycle of this rubber tree is as long as five or six years, and after five or six years, the internal worries of the Ming Dynasty have been resolved, and grain is no longer the primary condition for restricting domestic peace, then Lao Tzu has the initiative.

I said you can have as much as you want, and if you can't, you can just throw it into the ocean.

The interests of countries sometimes need to be flickered.

……

After the two biggest commodity problems were finalized, they began to decide on others, these are some commodities that Su Baiyi has the initiative to grasp, in addition to the porcelain and cloth of the Ming Dynasty, it is the soap and glass of Su Baiyi's Yuyuan.

As for the luxury of perfume, Nguyen Phuc Lan clearly refused.

"Your glass is more translucent than Western glass, and the widow has decided to do business with your Daming, and I don't know the price of this glass...... Su-sama may have some discounts? Ruan Fulan asked.

"Yes!" Su Baiyi said with a smile: "In our Daming, the price of an ordinary glass cup is one tael of silver for four, and the king is Su Baiyi's friend, so I will give you a solid price." In this way, except for the thermos cup, the rest of the glass products, whether it is a cup, a mirror, or a decoration, will be calculated at the price of five taels of silver and one stone. ”

Glass has a very many uses.

In addition to cups and mirrors, they can also be made into windshields, which are excellent items for light transmission and decoration, and Ruan Phuc Lan saw the huge commercial value in them, so he bought 10,000 stones.

It's just 50,000 taels of silver, and it's earned when it changes hands.

"And soap!" Ruan Fulan said: "This thing is very useful, we also need it, a lot of it." ”

Last time, Hou Fangyu had already brought a lot of them to them, and after Ruan Fulan got these things for his subordinates to use, he found them extremely easy to use. And this thing is very popular with the people, compared with the traditional laundry method, this soap is not only more time-saving and labor-saving, the key is to save cloth.

"A piece that weighs half a catty, costs fifty wen!" Su Baiyi said: "What is the price in Daming, I will transport it to Guangnan for the king for free, or fifty Wen, this Tong Su is not deceitful, the king can send someone to our Daming to inquire about the price." ”

The ratio of the cost to the profit of soap is about one to four, and Su Baiyi will transport this thing to Guangnan, and the cost will increase again, but he is not ready to increase the price.

Because the object of his business is not the common people of Annam, but the official of Quang An, it is foreseeable that Ruan Fulan will definitely sell the soap at a high price for a profit after getting it. If Su Baiyi sets the purchase price too high, it will cause the final selling price to continue to increase, and once the price is inflated, the people will not be able to bear it, which will cause a decrease in sales.

After weighing the pros and cons, I can only give some profits to Nguyen Phuc Thi.

Su Baiyi suddenly understood why the Western powers that invaded China at the end of the Qing Dynasty signed treaties after defeating China, and opened treaty ports every time.

So that's what happened!

After the specific terms and prices are negotiated, the agreement is signed.

Su Baiyi took out two contracts, one was a national document, which stated the price and quantity of rice purchased from Annan, as well as some other Ming products; The other is Su Baiyi's own contract for the Yuyuan, which is written about the export of glass and soap, as well as the agreement on the cultivation of rubber trees.

After everything was done, Ruan Fulan took the agreement in his hand with a smile, looked at it and confirmed that it was correct, and then said: "Envoy, the business is over, let's talk about the alliance." ”
