Since Tang Qi returned to Dahan, he would come up with something from time to time to surprise Liu Che.

made Liu Che sigh more than once that the decision to "transport" Mr. Tang back to Chang'an even with shame was really one of the most right things he did in his life.

However, even if Liu Che thought that he already knew Tang Qi's magic, every time Tang Qi came up with something, he could still constantly refresh his three views.

For example, now.

Soybeans can actually produce oil?!

Is it the "oil" he thought, no mistake!

Princess Pingyang had already prepared and hurriedly presented the oil bowl.

Because of the bumps in the carriage and the galloping all the way, only a third of the half bowl of oil was left at this time.

Princess Pingyang's body is full of oil stains.

But no one cared at all at this point.

Liu Che carefully took the bowl, as if he was holding a treasure worth ten thousand gold.

Sniffed, and said in surprise: "Sure enough, it's not the smell of meat oil, I've never smelled this fragrance before!" ”

"Sir's immortal skills are really all tools for the benefit of the country and the people, which is completely different from those Taoist priests who only know that alchemy harms people all day long!"

Tang Qi rolled his eyes.

Comparing science and technology with alchemy is simply an insult to science!

As for the immortals who are not immortals, they don't have the strength to argue anymore.

If you love immortals, you are the emperor and your boss.

"Bang!"

Liu Che put down the bowl abruptly and splashed the oil all over the table: "This law can live thousands of people, and the local officials should be ordered to announce it to the world!" ”

"Wait!" Tang Qi immediately interrupted, "You can't do this! ”

Princess Pingyang also spoke at the same time as Tang Qi: "Your Majesty think twice!" ”

Liu Che was at a loss: "With such a method that benefits the country and the people, how can it not be announced to the world?" ”

Princess Pingyang looked at Tang Qi hesitantly, as if she was worried that stealing his limelight would make him unhappy.

Tang Qi arched his hand gracefully: "The princess said first." ”

There are already a lot of limelight on his own, and he is not bad for such a one.

What's more, if some words are spoken, they are destined to offend many people with vested interests.

Since the sister of the Son of Heaven is willing to come forward, of course she is willing to be willing.

Princess Pingyang breathed a sigh of relief and said solemnly: "May I ask Your Majesty, why do you think that the law of soybean oil is beneficial to the country and the people?" ”

"Do you need to ask?" Liu Che was puzzled, "Naturally, because soybeans are common, if this method is promoted, people all over the world can afford to eat oil." ”

Princess Pingyang asked again: "After the news of soybean oil production spreads, does Your Majesty think that soybeans will be 'cheap'?" ”

"How won't it ...... No, Sister Huang is right. ”

Emperor Wu of the Han Dynasty was the Emperor Wu of the Han Dynasty, and he was splashed with cold water by Princess Pingyang, and he quickly reacted.

Soybeans are cheap because they are easy to feed and have little economic value.

The rich and powerful disdain to plant, so that the poor people have more food to eat.

If everyone in the world knows that soybeans can make oil, and whether the price of oil will fall, the price of soybeans will really rise.

But that doesn't mean that the people who grow beans can make a profit!

In order to compete for the huge profits from selling oil, the landlords and powerful people will even prohibit the people from eating beans, and instead collect soybeans under various pretexts.

It is then refined into oil and continues to be sold to the people at a high price!

When the time comes, local officials and businessmen collude, and the people will not only be unable to eat cheap and good oil, but they may not even be able to afford bean rice!

Don't think it's impossible, sheep can eat people in Europe, so what's so strange about the Han Dynasty having "beans eating people"?

In fact, since Liu An, the king of Huainan, made tofu and soy milk, the price of beans has risen a lot.

At that time, even if Liu Che wants to manage it, but the officials protect each other, and the emperor is far away, how can he manage it?

At most, it can only keep the people of Chang'an from suffering, and no matter how far away, how easy it is for officials to deceive the Holy Hearing.

Untouchables, do you still want to go to Beijing to find the Son of Heaven to complain?

I'm afraid that when the time comes, the corrupt officials and the powerful will make a lot of money, and the people who are far away from Chang'an will not even know that soybeans can be squeezed for oil!

Wait for the big mistake to be made up for it, and then there will be countless closely connected interest groups around soybean oil, and it will be difficult to shake it.

"If it weren't for the imperial sister's reminder, I almost made a big mistake!" Liu Che smiled bitterly, "Actually, the promotion of sweet potatoes and potatoes alone has brought me a lot of trouble. ”

The reason is also very simple, the local people are unwilling.

If there is so much food that even the poor can eat enough, how can the grain merchant live?

How else to manipulate food prices and make huge profits?

How could officials, who rely on the subsidy of grain merchants to enjoy fine food and clothing, agree to promote sweet potatoes so easily?

Even if they dare not oppose it because of the general righteousness on the surface, they will make a little stumbling block at the practical level, and even incite the people who do not know the truth to make trouble, what is the difficulty?

Even if you are the Son of Heaven, you can't still check one state, one county, one mile!

What's more, today's Han is worried about internal and external troubles, and it is not a good time to crack down on these local forces.

These days, Liu Che is annoyed with a headache.

Tang Qi understood very well.

The current Emperor Wu of the Han Dynasty has just achieved defeat against the Xiongnu, and the Xiongnu are completely enraged and have put on a posture of wanting to fight to the death.

Whether it can continue to win or not, there is no bottom inside and outside the court.

There was a rebellion of the king of Huainan in the territory, and the vassal kings in various places were also ready to move, and even colluded with the Xiongnu.

The prestige of Emperor Wu of the Han Dynasty is far from being as high as after expelling the Xiongnu to the depths of the desert, and it is also necessary to carefully check and balance all parties.

"But do you want to give up? If the people of the world can eat cheap and good oil, not to mention anything else, the soldiers of my Han can be much stronger! Liu Che was still unwilling, "I don't know if Sister Huang and Mr. Tang have a way to share my worries?" ”

Princess Pingyang can point out the problem, but she can't solve it.

can only look at Tang Qi with anticipation.

Tang Qi does have a way, otherwise he would not be so unscrupulous to come up with new technology.

"Chen has an idea, which may not be immediate, but it can gradually achieve the purpose of promoting soybean oil." Tang Qi smiled, "Your Majesty, why don't you open a cheap supermarket?" ”

"Cheap supermarket?"

The noun that he had never heard made Liu Che and Princess Pingyang very confused.

"A cheap supermarket, as the name suggests, is a store that sells a variety of goods at low prices." Tang Qi briefly explained the concept of supermarkets in later generations, "The price is clearly marked, and there is more than one kind of product, all of which are placed on the shelves for customers to choose." ”

"After the epidemic in Chang'an is opened, it can also chain supermarkets to various states and counties in the form of agents." Tang Qi said, "At that time, the price of goods in the supermarket will be all determined by us, and it will be the same everywhere." You can put an end to the idea of hoarding by oil merchants! ”

The method of making soybean oil is actually not difficult, but the difficult thing is how to prevent the monopoly of corrupt officials.

Liu Che's eyes lit up: "The method Mr. said is fresh, but if the price is the same in various states and counties, how to attract merchants to join?" ”

"Who says we're attracting merchants?" Tang Qi blinked, "Your Majesty, not everyone knows how to do business. At that time, the operation and management will have the head office to send people, and the people who have invested in the shares will only need to lie down and wait for the money to be collected. ”
