Datang: Time travel in two months, wait online, hurry up!

"This wave of mine is indeed too short-sighted!"

"What is the level of food production? If there is not enough food, then go to lay down a piece of land, if not, then lay down another piece!"

Other netizens were also confused by this person's reply.

However, everyone quickly realized that this idea is indeed simple and crude but also very effective, and immediately apologized below!

Li Ke continued to read for a while, and found that everything was almost the same, and there were no new replies, so he opened the notebook.

Also draw a few branches on the big tree of 'M'.

Then key information such as 'conventional rice seeds', 'wheat seeds', 'curved plow', 'drum car', 'overseas crops', 'increased cultivated land' were written on it.

"What about cooking oil? What kind of oil did ancient people eat?"

"In the Tang Dynasty, sesame oil should be eaten. Since Zhang Qian brought sesame back from the Western Regions in the Han Dynasty, the ancient people's cooking oil was mainly sesame oil."

"Then when did the rapeseed oil we eat now start to eat?"

"After the Yuan and Ming Dynasties, rapeseed was introduced to China during the Eastern Han Dynasty, but there were few people growing it at that time."

"Due to the immature crushing technology of soybeans at that time, the oil yield was very low, so few people used soybeans to squeeze oil."

"Peanuts were introduced to China in the late Ming Dynasty, but like soybeans, the pressing technology was not in place and the oil yield was low."

"It wasn't until the end of the Qing Dynasty, when electric oil extraction machines were introduced, that the oil yields of soybeans and peanuts soared, and gradually became mainstream edible oils."

"Up to now, it has formed a situation of soybean, peanut, sesame oil in the north and rapeseed oil in the south."

After watching for a while, Li Ke got a general understanding of the situation of ancient edible oil.

To put it simply, at the time of Datang, people mainly ate sesame oil.

Rich families may eat some animal oil, such as lard and so on.

So for him, if he wants to make money through cooking oil, he needs to increase the types of cooking oil.

It is easy to understand increasing the types of edible oil. He can produce rapeseed oil and soybean oil.

As for peanut oil, because peanut oil was introduced to China from the Americas in the late Ming Dynasty, there were no peanuts in the Tang Dynasty.

The peanut seeds can only be brought over after the fleet goes to America.

But more rapeseed oil and soybean oil are enough, plus the original sesame oil, three kinds of oil are enough.

Besides, there is animal oil, and lard can also occupy a large proportion.

Three vegetable oils, two unique to him.

And once you get peanuts from America, adding peanut oil will monopolize three kinds of vegetable oils!

Doing a monopoly business, can it not make money?

He only needs to control the price of cooking oil to a price acceptable to ordinary people, and he can make a lot of money casually!

After all, one cannot live without oil!

Rapeseed oil and soybean oil are exclusive to him. Even if someone learns from him to extract oil from rapeseed, what about soybean oil?

He can come up with a steam engine and use steam power to extract oil, can others?

Therefore, there is still a lot to do in the field of edible oil!

He painted several branches on the big tree 'Oil'.

Swish swish!

'Rapeseed Planting', 'Rapeseed Oil Pressing Technology', 'Soybean Oil Pressing Technology', 'Peanut Oil Pressing Technology', 'Principles and Drawings of Oil Pressing Machines'.

He quickly wrote these key information on the drawn branches.

Randomly flipped through the notebook, and found that three big trees had become "luxuriantly branched and leafy".

"If these necessities in daily life are gathered together, it is really not to be underestimated!"

Li Ke looked at the information recorded in the notebook, and suddenly had a strong confidence in his heart!

He imagined that after traveling through the past, he would control the whole world of briquettes and matches, as well as most of the rice, wheat and cooking oil, and control the entire grain and oil market.

At that time, no firewood was burned, and the flint for the fire was thrown away.

Most of the rice and wheat he eats are sold by the grain shop under his name.

The cooking oil I eat, except sesame oil, rapeseed oil and soybean oil are all wholesale from him.

At that time, as long as he says a word, the price of cooking oil can rise or fall!

If he gets upset, the price of rice and wheat will skyrocket!

He is unhappy, everyone can't even buy a briquette or a box of matches!

If you can’t buy briquettes and matches, and you don’t need flint, you can’t even start a fire!

There is no rice for cooking and no oil for cooking.

At this time, there will be big troubles!

At this moment, who would dare to touch him in Datang?

Does Li Shimin dare?

If Li Shimin dared to touch him, the common people who had no rice to cook and no oil to cook would not hesitate to pull Li Shimin, the emperor, from the throne!

Therefore, these seem to be just small things in daily life, not inconspicuous.

But it can actually make a big difference in people's lives!

Someone said in the comment section that the main character accepted Li Lizhi and Li Mingda. I don't know if it's you or me. I don't understand.

Chapter 19 Sea Salt!Walk on two legs!

These things, in modern terms, can be collectively referred to as strategic materials!

If he has complete control over these strategic materials, then his status and influence will be too great!

So big that even Li Shimin, the emperor of the ages, dare not act rashly against him!

Because once something happens to Li Ke, the impact and involvement will be too great!

In the same way, when Li Shimin chose the prince, he would also take this issue into consideration.

If Li Ke is chosen to be the crown prince and the third emperor of the Tang Empire, then naturally everything will be peaceful and there will be no turmoil.

But if you don't choose Li Ke as the prince, no matter who Li Shimin chooses to be the next emperor, it depends on Li Ke's face.

Because as long as Li Ke is unhappy and manipulates the grain and oil market a little bit, the world will be in chaos!

Li Shimin himself was the emperor who killed his brothers and sat on the throne, so naturally he would no longer want to see his sons have a tragedy of fraternal cannibalism.

Therefore, Li Shimin's only choice is to choose Li Ke as the prince!

And this is the benefit of controlling strategic materials!

That's why after he saw those three 'luxuriant' trees, he felt strong confidence in his heart!

Moreover, the three items of firewood, rice and oil are not enough, there are other strategic materials behind!

"We've talked about daily necessities, but we also need to talk about the equally important salt!"

"Salt was a very important material in ancient times, and even private individuals were not allowed to operate the salt industry, all of which were exclusively operated by the government."

"Not bad, but what I ate at that time was coarse salt, which was of poor quality and not very tasty."

"The owner can ask Li Shimin to obtain the right to operate the salt, and then go to the seaside to dig a batch of salt fields to dry the salt. Using advanced technology, he can produce exquisite snowflake salt in large quantities at low cost!"

"Salt cannot be sold privately after all. I suggest that the landlord and Li Shimin cooperate to open a royal salt company. The landlord will produce the salt, and Li Shimin will provide the business license. You will share the profits [-]-[-]!"

"That's good, as long as the landlord puts the white snowflake salt in front of Li Shimin, and tells him that the production is large and cheap, Li Shimin will not be tempted!"

"It seems that [-]% of the profit has been distributed, but there is still [-]% in the hands of the landlord, and the production of sea salt is also the responsibility of the landlord. The landlord is equivalent to being able to reasonably control a strategic material, which has once again strengthened its heritage and influence. !"

"And salt is something that is used in every meal. If it is really spread out and occupies the market, it can also make a huge fortune!"

After rice oil, it is naturally salt.

Salt is a very important material, even as important as iron in ancient times!

You must know that in ancient times, grain could be bought and sold privately, but only salt and iron could not!

Iron cannot be bought and sold privately, and everyone knows the reason, because iron can make weapons!

If someone sells a large amount of iron to the enemy country, it is equivalent to sending weapons to the enemy, which is obviously absolutely not allowed!

And even if it is not sold to the enemy country, if an ambitious person buys a large amount of iron resources and builds their own weapons, this is also a serious threat to the court.

Therefore, private trading of iron is strictly prohibited.

As for salt, although it is far less threatening than iron, salt is also a necessity of life.

The profit in it is very big!

From the Spring and Autumn Period and the Warring States Period, Guan Zhong began to monopolize salt and iron.

At that time, the emperors discovered the huge profits brought by salt, so they directly designated salt as a material exclusively for the government.

The reason why only government transactions are allowed, but not private transactions, is actually because it is too profitable!

First of all, with such a large profit, the imperial court will naturally have a large amount of income when it takes the treasury. Whether it is used for people's livelihood or for the army, it is good.

Secondly, if such a large profit is taken away by private individuals, it will also be an extremely unstable factor for the imperial power.

Therefore, salt was designated as a material exclusively owned by the government, and private individuals were not allowed to buy or sell it.

In the Tang Dynasty, once involved in smuggling salt, at least he would accept the spine stick, and at worst he would be exiled directly!

In the most serious cases, even the death penalty!

Therefore, if you want to do the salt business in the Tang Dynasty, you still can't get around Li Shimin.

"The quality and taste of ancient salt is indeed not good, far inferior to modern refined salt."

"The easiest way is undoubtedly to dig a salt field by the sea to dry the sea salt. As long as the sea salt is dried and processed into refined salt, it will definitely kill people in the market!"

"But in addition to sea salt, well mine salt cannot be ignored, which is also a major source of salt!"

Li Ke didn't ignore well and mine salt because of sea salt, he thinks both are equally important!

Because sea salt is sun-dried, and sun-dried salt requires a very important condition, sunshine!

The hotter the sun the better!

Therefore, the golden period of drying salt is from June to September every year, which is the time when the temperature is the highest and the sun is the most poisonous.

Under such climatic conditions, the drying of salt naturally goes smoothly.

But in winter, when the temperature is low and the sun is not poisonous enough, the efficiency of drying salt is definitely not as good as in summer.

The amount of salt that is exposed to the sun will definitely be much, much less.

But the amount of salt consumed every day will not change with the seasons. If there is less sea salt, it will naturally cause a shortage of salt.

At this time, well mine salt is needed to supplement!

Well mine salt is the salt mined from the ground by mining, and it is also the main source of salt eaten by ancient people.

This is not affected by the season, only by the mining technology.

As long as he brings the advanced mining technology over, the output and quality of mine salt can also be greatly improved.

It's just that well mine salt needs a salt well, which is costly, while the source of sea salt is sea water, which has almost no cost.

"Although there is a certain cost, it is safer to walk on two legs."

Li Ke's character and acting style are rather prudent.

He feels that sea salt alone is not enough, the combination of sea salt and mine salt is the most perfect!
