Forty stone of rice is exchanged for a horse of silk, and if Li Ke's cost is calculated, the profit is about one hundred and twenty times, okay, drizzle.

According to the profit of other merchants, about thirty-two times the profit, which is okay.

Li Ke really doesn't know the price of rice in real wax, his Yuelai firm has business in real wax, but these businesses are not much, and the amount of trade is not large, the most important thing is that the transport ships are not comparable to the transport ships in Li Ke's hands, and the transportation costs of the two sides are not at the same level.

Of course, the main reason is that Li Ke didn't ask Yuelai Commercial Bank, because in Li Ke's opinion, the folk rice price of real wax has no need for reference at all, because Li Ke is not ready to buy it with copper money at all, although it can also use Datang's copper money in real wax Linyi, but Li Ke is not ready to buy it with money at all.

Because when money is used to make an equivalent, it is easy for the other party to obtain the real price, and in this kind of trade, bartering is the most profitable way to make profits.

For example, more than a thousand years later, when the Red Big Brother disintegrated, those who made a lot of money by reselling at the border, who used currency to settle it, were all bartered, because this is the most profitable way to earn.

But Li Ke knows people's hearts, he knows that this price is definitely not the bottom line, if he continues, he can find out a lower bottom line.

"Princess Su Yeli, I like a win-win situation when doing business with people, so I can accept forty stones for one such silk." Li Ke simply agreed.

Su Yeli breathed a sigh of relief instantly, fortunately, His Royal Highness is a person who likes win-win! Soon her heart was full of surprises, such a silk may only be worth a few hundred wen in Datang, but it takes at least three yuan to buy such a silk in real wax, and the price of grain in real wax has to be converted according to the copper money of Datang, and a stone of rice is only thirty or forty wen yuan at most.

Such a price means that she can make a lot of money in real wax, and if she sells these things to the next countries such as the Mule Country, the Queen Kingdom, the Baitou Kingdom, Zhu Bo, and the Sanban Country, she can also make a large profit, and the things of Datang can also be sold at an extremely high price in these countries.

"But do you really have so much food?" Li Ke looked at her and asked.

True wax, which later became the eastern side of Cambodia, southern Laos, and the vast area of southern Vietnam, occupied the main basins and tributaries of the lower reaches of the Mekong River. But Li Ke didn't know much about the population of real wax and the food planted, and even the Tang Dynasty didn't have much information about this in this era.

"Your Highness...... Do you just need food? Su Yeli paused and asked.

"Grain, gold and silver, I don't want anything but these other things, and the latter says that there are not many other things." Li Ke said lightly.

"Food...... If Your Highness gives me time, I can scrape together at least seven million stone grains this year! Next year I'll make that number more than 10 million stones! Su Yeli took a deep breath.

Li Ke looked at her, this princess knew more things than Li Ke imagined, and she seemed to be a person who ran around and played with flowers, and this knowledge was indeed relatively extensive.

10 million stone grain, this amount is a huge number in Datang, and the reason why she said this is that Li Ke is sure that the real wax before must not have grown grain with all his strength! This is normal, other businessmen can't buy grain like Li Ke, the reason is very simple, there is no shortage of grain in Lingnan Road, but when it is transported to the territory of Datang, ordinary ships can't transport much, for ordinary merchants, when the volume is not so large, it is too much to transport grain.

Real wax, these medicinal herbs are more money than food!

Only Li Ke has the ability to transport a large number of grains, 10 million stone of grain, in fact, it is only 600,000 tons, and Li Ke's strategic warehouse has 500,000 tons of pork alone! A special cargo ship with a displacement of 1,200 tons can carry about 1,000 tons, and 10 million stones can be transported back to Datang in 600 trips!

This amount is nothing at all, Datang is not afraid of a lot of food, especially real wax, where rice is grown! Rice is more nutritious than corn, and ordinary people basically didn't eat it before, that is, they could eat it occasionally.

In ancient times, food was the foundation of all things, and when Datang did not lack food, this meant that the bran produced by the hulling of wheat and rice could be used to raise poultry, whether it was fed to pigs or fed to chickens and ducks after stirring, it was already considered a grain.

In the winter in the northern regions, this is one of the main food sources for poultry! This means that the people of Datang will gradually be able to eat meat! The people can eat meat, the physical fitness of the people of Datang, and the population will increase dramatically, and the population is the fundamental.

If the current Tang Dynasty has a population of 1.4 billion in later generations, it would be good if Li Ke played any war and emigrated directly.

What is the world's population now? So, population is king!

As for why he didn't knock down the real wax to grow grain, Li Ke naturally also considered it, now there is no shortage of arable land in the Tang Dynasty, and it is actually more difficult to forcibly immigrate at this time, but just occupy the local area and use the local people to grow grain, it is natural to have a bowl of water.

A bowl of water is flat, and Li Ke also makes a fart profit.

It seems that the land area has increased, but in fact, it is useful to leave some countries appropriately, at least Datang is still accumulating strength for the time being.

And besides, as long as Li Ke gives them enough profits, they will start to force the people to grow a lot of food, as for the contradictions between them and the people, what does Li Ke have to do with them?

A few years later, the Tang Dynasty took them, and the people rejoiced and applauded to welcome the arrival of the Heavenly Empire's king, which was Li Ke's purpose.

"Not enough." Li Ke shook his head very dryly, "Ten million stones is even a basic starting price, at least twenty million, or even thirty million stones." Li Ke replied very simply.

"Yes!" Su Yeli decisively agreed, but it was a big deal that she went to buy from countries like Mule Country, which are also very suitable for growing rice, and their situation is similar to real wax.

When she agreed, Su Yeli was also glad in her heart, this time she was right to come to Linyi, otherwise, how could she have such a big opportunity?

"But there's a problem." Li Ke asked faintly.

"Your Highness, please speak."

"Can you really take the market for real wax alone? Can you keep such a big profit? Li Ke took a sip of tea with a smile on his face.

Su Yeli pursed her lips tightly, she knew that this question was related to how much share she could take, or rather, it was related to whether she was out of this trade!
