I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

Lu Xuan was a little surprised. He knew how much Liu Tan valued soybean oil. Compared with other soybean products, soybean oil was his most beneficial weapon.

So according to Lu Xuan's understanding, he must keep the recipe secret, how come it is made public?

Although he blurred some places, such as how long it takes to steam and cook, as long as you know the whole process, you can try these details slowly.

It is much easier to know the result and try than to fumble a little without knowing.

Seeing Lu Xuan's surprised face, Liu Tan couldn't help laughing, "Because I changed the recipe."

From boiling to physical pressing, in fact, he used this method at the beginning because it is simple and easy to produce results, so that he has this support no matter how hard he tosses.

But boiling is indeed a waste of time, even without mentioning the wasted time, the wasted energy is also a lot, and the whole cannot be separated from the fire.

Liu Tan calculated that if he wants to expand production capacity, the external supply of briquette will inevitably decrease a lot. By then, the price of briquette will definitely rise in a straight line except for the northern border countries. It will become unaffordable, so firewood will be used.

In this way, the price of firewood will also rise, and people who can only use firewood for heating may not be able to afford it.

So basically it is a choice between many people and the economy of the northern border country.

Although Liu Tan has always focused on the development of the northern border country, it is impossible for him to ignore other Han people.

So he had to find another way out, so he began to improve the craft.

After trying a lot of methods, he finally found out that the first two steps of steaming and frying cannot be omitted, but there is an additional process before steaming and frying, which is crushing.

These beans need to be crushed first, then steamed and fried, and finally squeezed.

This method is pressing soybean oil in the traditional sense, which saves a lot of briquettes compared to boiling.

Liu Tan and Lu Xuan have nothing to hide, the main reason is that even if Lu Xuan knows this recipe, he can't make it out, so no matter whether it is the current Wusun Kingdom or the territory that Lu Xuan wants to fight for in the future, there will be no What about a place suitable for farming?

In other words, there is no place suitable for farming food.

It is not that there is no land for cultivation in the Huns, but the output is too small, and the nomads have become accustomed to such a life, so it is really difficult for them to cultivate.

Lu Xuan frowned: "But these people will also want to sell soybean oil after they know the recipe, so wouldn't this consume a huge amount of energy?"

Liu Tan shook his head: "It's not the same. They want to make money. Even if it's the same thing, I can make it at a lower price than theirs. Even if the transportation cost is included, it's much lower. If they lower the price, they will lose money. I can make money, so I am not afraid of price wars, and in the end they can only withdraw from the market."

Lu Xuan curiously asked: "Then what if they can also research it?"

Liu Tan didn't hide it from him: "I knew that it took a lot of time to explore the specific process of this method, otherwise I might not have used the method of boiling in the first place. They have to be so good to find the right method The method? Even if they figure it out, it will be more difficult to purchase than us. Now the soybeans in Qi State or Changyi State should be of the best quality. It doesn’t matter if these two places are found. Fu Ling and Liu Mao's temperament, they will definitely set a high price to make money when they get this thing."

Lu Xuan was a little surprised: "What about you?"

Liu Tan shook his head: "My purpose is to change the types of cultivation in the northern border country. If it is not suitable, you have to grow glutinous rice or the like. If you work hard to the end and the harvest is not good, that is a vicious circle, so I The price is probably set so that there is a small profit after all costs are removed, and it is enough to pay taxes."

Lu Xuan somewhat understood Liu Tan's meaning. There is no way to forcefully change things like asking everyone to change things. Liu Tan can indeed give orders, but others can also obey others.

Only when people find that growing soybeans is more profitable than growing other things, will these people be willing to switch to soybeans.

Lu Xuan suddenly realized with a smile: "You deliberately let those people know the recipe, maybe you want them to help you spread it?"

Liu Tan nodded vigorously. Although these people were all by Liu Che's side, they came from all corners of the country, and few of them had their ancestral home in Chang'an.

These people won't dare to do this in Chang'an after they got the prescription, it seems to be the private land of the great nobles.

So they will definitely do this in their hometown, so that first of all, more people know that beans can produce oil, and they are very cheap.

It also saves Liu Tan from having to send someone to explain the origin of soybean oil first if he wants to promote it. It is too tiring.

And Liu Tan doesn't intend to kill them all. First, let these people get the profits in the early stage, and then compete with them for the market with lower prices and higher quality in the later stage.

The only thing to worry about is that those local snakes will make trouble, this... there is no way for the time being.

In fact, the best way is to cooperate with the princes and kings, but the problem is that Liu Tan is not very close to those people. Apart from the thin blood relationship, they are worse than strangers-many people are treated preferentially because of Liu Tan And jealousy.

Lu Xuan rolled his eyes and said: "If you want to come to this thing, there will be people in the Western Regions who will like it."

Liu Tan waved his hand: "Don't worry, let's see the situation."

In addition to finding a way out for the northern border country, he did this more to change the diet structure of the Han people.

A small amount of soybean oil may not change anything, but with so many soybean products, people can supplement more protein at a lower cost.

So even though his place is closer to the Western Regions, the transportation is more convenient, and the price may be more affordable, he still wants to give priority to the common people.

Of course, Wusun State is an exception, because Wusun State can be regarded as the common people of Han Dynasty now.

But this matter should be handled by the people below. It's not that Liu Tan doesn't want to do business with Lu Xuan to raise money, but that the two of them have less time to spend together, so why waste it on this kind of thing?

After Liu Tan finished speaking his thoughts, he turned his head and asked, "When are you going to tell my father?"

Lu Xuan smiled and said, "Didn't you already tell His Majesty?"

"That's different. I'm just saying hello to Father, and trying to get him to support you by the way. However, it seems that Father's attitude is rather ambiguous. It depends on you whether you can do it."

Liu Tan was very calm about not being able to persuade Liu Che. Except for Liu Che being more persistent and credulous in the matter of seeking immortals, other things are fine. If he is so easy to be persuaded, he is afraid The court has long been unable to continue.

And the most important point is that Liu Che probably wants to hold the minerals there, but now the big man is not suitable for war with the Xiongnu.

Wusun is very suitable. Although it is a vassal state of the Han Dynasty, Lu Xuan has always sent troops at will. It is estimated that the Huns will not think that Lu Xuan is sincerely seeking refuge.

And it doesn't matter even if the account is hung on the big man. The big man doesn't want to fight, and the Huns don't want to fight either.

Therefore, it is estimated that Lu Xuan should discuss this matter with Liu Che in person, how can Liu Che be assured.

Lu Xuan is not worried, he believes in Liu Tan, so he believes that there are minerals there, but the problem is that Liu Tan also said before that Qi and Changyi state-owned minerals, haven't they found it yet?Uncertain things are not worth fighting for.

He said: "Your Majesty has to rest for a few days, so let's wait."

Because Liu Che came here this time to escape the summer heat, unlike the last time he was in a hurry, the whole itinerary was arranged very easily. No matter what kind of trip it was, Liu Che could go if he wanted to, and he didn't want to.

When Liu Che woke up, it was already dark, and it happened that Liu Tan accompanied him around the Longevity Palace, and then he could prepare dinner.

It was done like this two days ago, but today Liu Che didn't want to go out and called Lu Xuan over.

After Lu Xuan came over, Liu Tan originally wanted to quit first, not because he was afraid of Liu Che thinking too much, but because he was not very good at fighting, and he didn't understand well.

But Liu Che kept him there, and after Lu Xuan sat down, he asked lazily, "Tan'er said you have something to report?"

One advantage of Lu Xuan is that he knows that he is probably not Liu Che's opponent, so he has always been very straightforward in front of Liu Che, so he said directly: "My minister and other countries want to fight for the land south of Yanran Mountain."

"why?"

Liu Che was very interested in Lu Xuan's motives. Through Liu Tan's narration, he knew that Lu Xuan had just made up his mind and didn't even know there were mines there, so he planned to migrate there from the very beginning, which made Liu Che a little strange. .

In real comparison, the climate and land there are not much better than those in the Western Regions, and may even be worse.

Lu Xuan is very calm: "The Western Regions cannot be dominated by one family. Wusun already has enough influence in the Western Regions. The most important thing is that Princess Danyang is now in power, and will further affect the Western Regions. It is not good for me to stay there."

Not to mention that Princess Danyang has ambitions herself, even if she doesn't have ambitions, the big man will push her to continue. If she can't, let her actual husband or their son come. Anyway, it's best for this land to fall into the hands of the big man. People rest assured.

Liu Che nodded and asked again: "What else?"

Lu Xuan's eyes flashed and he said, "This will further cut off the Xiongnu's control over the Western Regions."

How long has the big man and the Xiongnu fought for the Cheshi country in the Western Regions, and you have won and lost in this, but generally speaking, the big man still suffers a bit.

The Western Regions are the portal for Han to communicate with other countries, and it is also the only portal now.

To the east of the Han Dynasty is a large area of ​​ocean, to the north is the Xiongnu, and to the west is a part of the plateau. Therefore, except for the Western Regions, it is necessary to go south to communicate with other countries.

However, there are a large number of small countries in the south. Over the years, the big man has sent envoys there, but those small countries have not been very respectful to the big man because of their geographical advantages. Most of the missions sent there never return.

In fact, the same is true for the road leading to the Western Regions, but Zhang Qian fought hard and finally opened up a road. This road is too important for a big man to give up, so he needs to hold this road in his hands.

If he can help the big man open up the road to the Western Regions and stabilize it, then Lu Xuan will have more confidence.

He spoke clearly, and Liu Che didn't bother to ask him in circles, "What do you want?"

Lu Xuan said: "Don't want anything, just... If you don't win, don't blame me."

Liu Che looked at him with a half-smile: "Is there really no request?"

Lu Xuan hesitated a little, and finally said cautiously: "There is no other request, that is, if the minister really wins, can he build a palace there?"
