Soybeans are everywhere these days, but no one compares them to oil.

It's not that the ancients were stupid.

It's today's oil, which is almost all meat oil.

The concept of vegetable oil has not been deeply rooted in people's hearts, and the preparation of food is nothing more than boiling, steaming and roasting, and it is not easy to find vegetable oil.

In fact, even after the discovery of vegetable oil, the ancients used sesame oil for a long time, and soybean oil was not discovered until later.

And now Zhang Qian has not yet made a second mission to the Western Regions, and sesame seeds have not yet been introduced to the Han Dynasty.

Therefore, soybean oil is a commonplace thing for Tang Qi, but for the people of the Han Dynasty, it is tantamount to another three-view earthquake!

Princess Pingyang stared at the beans with blazing eyes, and held the palm of Wei Yan's small hand, which tightened unnaturally.

Wei Yan was pinched, but he didn't make a sound very sensibly.

From his mother's expression, he sensitively knew that he seemed to be witnessing a big event.

The Hou Mansion had plenty of manpower, and in a short time, all the fried beans were smashed into fine granules.

The next tools are not readily available.

Fortunately, the mansion is big enough, and there are a lot of rockeries.

Tang Qi was not interested in appreciating the garden, so he simply asked people to go to the rockery group and knocked a large and heavy boulder.

Thanks to the pulley block, the lower people are carried quickly.

This small tool has been known by Liu Che and passed on to craftsmen all over the world, so it has not attracted the attention of Princess Pingyang.

All her attention was on the inconspicuous pile of soybean flour.

Wrap the crushed beans in a cloth and place them on a flat stone.

In accordance with Tang Qi's instructions, a notch was made on the stone specifically for oil leakage.

Then press another boulder against the cloth bag.

Grind slowly.

At this time, the people basically knew what Tang Qi was going to do, and the strong man who was in charge of grinding the crushed beans even held his breath.

Soybeans, can they really produce oil?

Under the expectant and nervous gaze of everyone, time passed quickly.

It is not difficult to get oil out of beans.

"Tick!"

A drop of golden liquid slowly dripped down the notch into the large bowl that had been prepared earlier.

"It's oil!"

"It's oily!"

The people were so excited that they almost jumped up, and the cheers resounded through the sky.

The steward, who was over 100 and a half years old, walked to the bowl tremblingly, dipped some soybean oil with his fingertips, and carefully put it in his mouth.

"It's really oil!"

The steward was so excited that he burst into tears.

"The sky is above, this is oil!"

Don't look at the steward's appearance that he has never seen the world, Princess Taiping's performance is not much better.

She squatted down regardless of her image, staring carefully at the notch that was dripping oil, breathing very softly.

As if worried about disturbing something, the beans no longer produce oil.

And Princess Taiping's eyes also contained tears.

If you don't live in ancient times, it's hard to understand the excitement of the crowd at this time.

Oil!

Salt!

Both of these are serious problems that restrict the living standards of the ancients!

Especially in the Han Wu Dynasty, where the productive forces were not yet developed, no matter how strong the military was and how brilliant the culture was, it could not hide the fact that even the good family was reluctant to let go of the use of oil and salt.

In the homes of poor people, a piece of salt stone and a piece of pigskin can survive for a year.

Even the steward of Tang Qi's mansion still rolls around in pigskin to eat oil at home, which is a little better than the people, but it is just enough to meet the health needs.

That's the steward of the Hou Mansion!

It can be seen how serious the lack of oil among the people has become.

And now, Tang Qi told them with facts that soybeans, which even the poor can afford, are actually babies that can produce oil!

How can it not be exciting!

Among the people present, the only one who could stay calm, except for Tang Qi, was only Wei Yan.

Tang Qi is not surprised.

Wei Yan is still young, although he understands what the adults are excited about, but he can't empathize.

He raised his little face and asked crisply: "Da Nong Ling, beans can really produce oil!" ”

"That's right, not only soybeans, but other beans can also be used." Tang Qi pinched Wei Ling's little face, which was still a little baby fat, "But soybeans produce the most oil, and they are also the most cost-effective." ”

"Settle down!"

Princess Pingyang suddenly shouted, and her sharp voice startled Tang Qi.

I thought it was a very serious thing to pinch a child's face in the Han Dynasty, which made the child's mother angry.

But when she raised her eyes, Princess Pingyang's eyes were still sticking to the soybean oil.

"Dare to ask An Dinghou, you said that soybeans produce the most oil, I don't know how much oil can be produced?"

In the Han Dynasty, there was no damn saying that a woman was virtuous, and Princess Pingyang, as Liu Che's sister, also had the world in mind.

Tang Qiyun replied lightly: "With today's level of productivity, we can't give full play to the maximum oil extraction value of soybeans." ”

"The oil yield is about 20%, that is, ten catties of soybeans can squeeze about two catties of oil. However, there is no need to worry about waste, and the soybean meal left over from oil extraction can be made into soybean cakes, which are good for rice or poultry feeding. ”

"Although the rest of the beans can also produce oil, it is estimated that the oil yield will not reach 20%."

After sweet potatoes and potatoes spread all over the country, the people probably don't need to save even soybean meal as rations, and when the time comes, they can teach the people how to breed on a large scale, so as not to waste soybean meal.

Every time Tang Qi explained, Princess Pingyang's breathing became a little shorter.

Twenty percent!

Ten catties of soybeans can squeeze out two catties of oil!

"Sir, you're here to keep an eye on the oil." Princess Pingyang stood up suddenly, holding the big bowl that had already received half a bowl of oil in one hand, and grabbed Tang Qi's hand with the other hand and walked out, "Settle down, follow me into the palace to see Your Majesty!" ”

"Eh, eh, wait!"

"Can't wait!"

Tang Qi was embarrassed to compare his strength with women, so he could only be passively pulled away, and at the same time his face was full of helplessness.

Do you want to be in such a hurry?

Isn't it just to make some soybean oil, and I haven't had time to say what I'm going to do next!

In the eyes of Princess Pingyang, of course she has to be in such a hurry.

One point faster, and the people of the world will also eat cheap and good oil one point faster!

is also a loss to Princess Pingyang who is not short of money, and knows the righteousness.

Changed to other high-flying and domineering royal relatives, at this time, I am afraid that what I am thinking about is how to seal Tang Qi's mouth to make a lot of money, instead of Ze being born!

Liu Che had just finished lunch at this time, and was about to ask if there was a military report on the front line to counterinsurgency, when he heard Princess Pingyang and Tang Qi urgently asking to see him.

Princess Pingyang doesn't say it first, every time Tang Qi appears, he can bring good things!

Liu Che hurriedly let people in, and then retreated.

Without waiting for him to ask, Princess Pingyang immediately said: "Your Majesty, there is a way to make soybeans produce oil, and the people of the world are blessed!" ”

Liu Che was half a beat slow to react, and stood up suddenly, not even noticing that he had overturned the pen and ink.

"What the royal sister said is true? Mr. Tang has immortal art again?! ”
