Live streaming life: The ancients begged not to stop

After dinner, Qi Cheng lay on the sofa and took out his tablet to continue browsing Dongyin. After watching a few dancing girls, Dongyin recommended to him some essential skills for time travel that had not appeared for a long time.

[Essential skill for time travel—oil pressing.]

[Once your faction has produced three acids and two bases, you will gradually be able to produce a variety of chemicals, gaining an overwhelming advantage over surrounding factions.]

【Not afraid of any storm. 】

[At this time, these neighbors are your granary, and your own land can be used to grow other crops to improve the monotonous meals.]

[The first thing I recommend is peanuts. ]

[Because peanuts can not only be used as vegetables, but also as oil, and in ancient times, the human body was quite lacking in oily foods.]

[Of course, if peanuts are not available, rapeseed can be used instead. ]

Daqin

Looking at the two plants mentioned by Tianmu, Qin Shihuang knew that peanuts were introduced relatively late, but he didn't know much about rapeseed. The host didn't say when it was introduced.

"Father, just ask Xu Shui. I heard he's been investigating the plants nearby."

Qin Shihuang paused for a moment. He was a little distrustful of Xu Shui. After all, it was really outrageous that he couldn't even see what was right under his nose.

"Let's go look for it. Even if we can't find this plant, it doesn't matter. First, learn the oil extraction technique, and then slowly experiment with various plants."

Liu Che was very happy. With more oil, the soldiers would be stronger, and he would be able to kill more of them when attacking the Huns.

But there is not much rapeseed in Dahan now.

"Have the Shaofu find suitable land for large-scale rapeseed cultivation, and then press it into oil according to Tianmu's method. Prioritize the allocation to the several armies in the north."

"promise!"

Ming Dynasty

Zhu Houzhao shook his head silently. It seemed that peanuts already existed in the Ming Dynasty, but the planting area was not very large, let alone ordinary people.

Almost all the land at home is used to grow crops.

There is no spare land to grow peanuts.

"How's the progress on the high-yield grain? Are there still no sweet potatoes in Luzon?" Zhu Houzhao asked loudly, "What other progress have you made?"

A young eunuch beside him whispered that nothing was found.

Zhu Houzhao was a little skeptical. Judging from the time, the high-yield crops had been introduced very close to the time when they arrived. It was impossible that he could not find them even if he looked for them specifically.

Could it be that those civil servants are causing trouble again?

I have to check it out.

Let's talk about the specific process. First, crack the peanuts, which means removing the shells and leaving only the peanuts inside. Then, fry the peanuts over high heat until cooked.

[The reason for doing this is to make the peanut oil more fragrant. ]

The roasted peanuts are cooled, crushed into powder, and then wrapped in cloth and steamed. This step further removes moisture and various microorganisms that can cause decay.

[Then the peanut powder is placed in a special oil pan, placed in an oil press, and then pressed, allowing the oil to fall into the collection pan below.]

[This is peanut oil. Of course, the soybean cake after pressing is also a very good thing and can be said to be very useful.]

First of all, this peanut oil cake is edible and very crispy when hot. It can also be used to feed livestock and is considered a very good concentrated feed.

[Another way to use it is to fertilize the land, so that the crops grown will be better.]

Qing Dynasty

The common people looked at Tianmu's introduction in amazement. At that time, most of them still used beans to squeeze oil, and the bean cakes were definitely not as delicious as those made with peanuts.

Even so, these bean cakes are not used to feed the fields. During the lean period, this is a very good food, but most people are reluctant to eat it.

If you use peanut bean cake as fertilizer, how much would the grown crops sell for per pound?

........

The sky screen depicts the appearance of a traditional oil press. Dynasties before the Han Dynasty tried hard to make the appearance more realistic, and strived to make this machine in a few days.

Dynasties after the Han Dynasty felt that this oil press was similar to theirs.

"Everything is so advanced in later generations, so why hasn't this oil press been improved much?"

"This is your first day seeing the sky screen, and you don't understand this. There must be advanced methods in the future. I think it might be to use electricity to squeeze it."

There are actually many crops that can be used to extract oil. In addition to the peanuts and rapeseed mentioned above, there are also soybeans and tea tree seeds that are native to our area.

[However, I would like to remind everyone that although cotton seeds can be used to extract oil, this oil needs to be specially processed, otherwise it will be harmful to the body.]

It will affect fertility.

Tang Dynasty

The emperor and his ministers of Li Tang looked at each other. Although they had not found the cotton yet, they had already thought of a way to use it, although the trick was a bit insidious.

But it should be very useful against enemies.

"Your Majesty, the most important thing now is to find the cotton quickly. We've been searching for it for so long, but we can't find any. This shouldn't be the case." Changsun Wuji said, "We've checked every minister's back garden."

Li Shimin also shook his head. He drew a picture of cotton and issued an edict to the whole country. As long as cotton could be found, money and beauties would be negotiated.

"I think we should send a few more envoys from the Western Regions. Their main mission this time is to visit the gardens of their nobles."

"Who's the right person to go?"

"Tang Jian, please."

……

Some people were stunned by Tianmu's introduction. Are there so many harmful effects of cotton seed oil extraction? Tianmu quickly asked them how to avoid it.

Most of them here eat cottonseed oil.

[The main reason for affecting fertility is that cottonseed oil contains a high content of gossypol. If possible, it is better to use rapeseed oil or peanut oil.]

There are many ways to remove gossypol, such as distillation and freeze crystallization, but no one can guarantee their effectiveness.

[Okay, that's all for this issue of the essential skills for time travel. Have you all memorized the oil extraction method?]

Qi Cheng thought about it carefully. They mainly eat peanut oil here. When he went to the oil mill when he was a child, he could smell the fragrance from afar.

Looking further back, families at that time also ate lard, but later everyone said that eating lard was bad for the body, and gradually no one ate it anymore.

However, many people now say that lard is actually good for the body and is much better than the blended oils sold now.
