The benefits of olive oil are too many, it is simply a good product for health, but unfortunately such a good oil Datang does not, so it is imperative to transplant some olive trees to Datang, as long as these olive trees take root in Datang, in the future, Datang will have a sufficient amount of olive oil, which has a great effect on improving the lives of the people of Datang, especially the rich group, the profit is the greatest, because even if Datang has a huge olive oil in the end, the poor are still reluctant to eat, only the rich will eat olive oil without scruples, So you can live a healthier life.

Not to mention the small countries, in terms of the current living conditions of ordinary people in Datang, it is already good to be able to eat vegetable oil, how can you dream of such a high-grade edible oil as olive oil.

In the homes of many ordinary people, the edible oil is mainly animal fat, such as edible oil refined from pork fat, which is the main cooking ingredient of ordinary people.

This is still a very ordinary people, if it is a poorer people, they can't even afford to eat the edible oil refined from fatty pork, so they can only eat some boiled vegetables, or eat some pickled dishes.

As for the families who can eat vegetable oil, they are at least the middle class such as small landlords, even so, not every meal can be eaten, many times they still have to eat refined animal oil, and for the fried snacks on the street, it is almost the world of animal oil, and there is no such thing as changing the oil, if the oil is less, then add a little to it, which can be described as extremely economical, and the harm to the body is very great.

Even if it is vegetable oil, it is harmful after repeated use, not to mention animal oil, which is very harmful, but for the people of the Tang Dynasty, which is not developed in science and technology, they can't see these hazards at all, so they will naturally not take it too seriously.

I have seen people who eat repeatedly fried snacks, I have never seen people who were poisoned and fell to the ground after eating, and even, some people have not been sick after eating for decades, so who dares to say that repeated frying of oil is not good for the body, how to get evidence, there were no advanced chemical instruments in the Tang Dynasty, and talking nonsense is slander.

And the reason why it is necessary to save so much is entirely because the materials of this era are not sufficient, natural disasters often occur, it is good to fill the stomach, how can it be so wasteful, after frying food, throw away the remaining oil, this is to be punished by God, it is absolutely not allowed.

Even if Li Ang set off industrialization, which greatly increased the crop yield and disaster resistance of Datang land, it did not change the concept of saving of the people of Datang.

This habit carved into the bones is estimated to be impossible to change in this life, just like many old people in later generations, who ate soil when they were poor in their early years, and after old age, due to the affluence of society, they no longer have to eat soil, but they still can't get rid of the problem of thrifting, and it is estimated that they can't change it until they die.

Because of the backwardness of oil refining technology, Datang's vegetable oil is mainly soybean oil and rapeseed oil, among which, the proportion of rapeseed oil is slightly larger, after all, soybeans have more important uses, no one is willing to use soybeans to extract oil, and the oil yield is also very low, not even one-tenth.

The main use of soybeans, that is, to make tofu and soy milk, in the minds of farming people, tofu has a very important role, because farming civilization can rarely have the opportunity to eat meat, and cereals can not supplement too much protein, which is very unfavorable to the human body, and after soybeans are ground into soybean milk, they can provide protein that can be easily absorbed by the body, that is to say, soybeans are plant proteins, which can greatly make up for the needs of farming nations for protein, so that people of farming nations become stronger.

Rapeseed is relatively speaking, the role is far less than that of soybeans, and the oil yield is higher than that of soybeans, so in the era of Datang, the most important vegetable oil is rapeseed oil, and soybeans are more used to make tofu food.

As for corn oil and peanut oil, it is impossible for Datang to have them, after all, these two things were brought back from the American continent after Li An sent people to discover the Americas, and now the quantity is still very small, and people are not enough to eat, how can they be willing to use it to extract oil, isn't this a tyrannical thing.

In this way, even if it is the emperor of the Tang Dynasty, the vegetable oil that can be eaten is only rapeseed oil, and the rest of the various vegetable oils have not had a chance to enjoy?

According to the historical records of later generations, animal oil has been used in ancient China, and it was not until the Han Dynasty that vegetable oil appeared, but vegetable oil was not used for food at that time, but was used to make silk cloth, and it was not until the Song Dynasty that there was a record of edible vegetable oil.

It's just that after Li An came to the Tang Dynasty, he found that the nobles of the Tang Dynasty had begun to eat rapeseed oil, although it was not very common, but he did see it, which shows that the historical records are not prepared enough, rapeseed oil has appeared in the Tang Dynasty, but there is no record of this in the history books, perhaps the reason for the insufficient popularity!

Long-term consumption of animal oil has great damage to people's bodies and will greatly reduce people's life expectancy, so for the health of the people of the Tang Dynasty, Li An feels that it is imperative to promote vegetable oil, at least, it must be implemented in the aristocratic circle first, and then, with the abundance of materials, it will gradually develop to civilian families.

Rapeseed oil is the most basic vegetable oil, and the reason why it has not been popularized on a large scale is mainly because almost all the land in Datang is used to grow food, and there are very few fields for growing rapeseed, so the quantity naturally cannot keep up.

What Ang Lee has to do is to continue to promote various vegetable oils, adding corn oil, peanut oil, soybean oil, and even high-end olive oil and flax oil on the basis of rapeseed oil.

Before, because of the backwardness of Datang's agricultural technology, most of the land had to be used to grow food, and only a very small amount of land could be used to grow other crops, but since the machine invented by Li An, and the high-yield crops from the Americas, Datang's food problem has been greatly alleviated. And soybean residue can be used to feed pigs, and it is much better feed than grass, it is easy to feed piglets into big fat pigs, and the yield of pork will be greatly increased.

In short, after the people can eat enough, a lot of idle land can be used to develop cash crops, and the life of the people of Datang will definitely be thriving.

It won't take too long, it will only take a few decades, the Tang Empire will be completely changed, and the people will not be hungry in the future, and the corresponding social security system will be gradually established.

Because olive oil is so beneficial, Ang Lee decided to bring back more, as well as a lot of olive and olive tree saplings.

On the way back, Ang Lee decided to use a delicacy made exclusively of olive oil, and never eat low-grade rapeseed oil again, as for animal fat, although the taste is very delicious, but if you eat it for a long time, it will cause a great burden on the body, so Ang Lee can try not to eat it.

Li Xiaolu was one step earlier in shopping for food on the street, because Li An gave her a lot of permission, so she instantly became the leader of the kitchen procurement team, she said to buy whatever she wanted, and the people who followed did not dare to say a word, anyway, the funds are very abundant, and there is no need to worry about not being able to afford it.

"Li Shilang, look at how many good things I bought."

Li Xiaolu walked towards Li An, followed by several carriages, which were carriages that hired locals, and the locals were also responsible for leading the horses.

"There are so many things, what are you buying!"

Li An looked at the huge goods on the vehicle and frowned slightly.

"Delicious food, good drink, fun, wear, use, commemorative significance, these are all bought, and the car can no longer be loaded, otherwise, can you buy more?"

Li Xiaolu said with a smile.

"Buy, buy, buy, know to buy, hahaha!"

Li An scolded with a smile.

It's human nature to like to go on a shopping spree, especially for women, because shopping can make people feel excited, and the more crazy they are, the more they can make people feel extremely excited.

Women are born to like shopping sprees and have not changed since ancient times, and excessive shopping can be regarded as a mental illness.

However, as long as you have enough money in your hand, then you don't have to be afraid of anything, being willful when you have money is definitely not an empty word, as long as you have money, even if you can't control your desire to consume, it doesn't matter, just rest assured and bold to buy it, anyway, there is money.

Therefore, it is good to be a rich man, buy whatever you want, and don't deliberately suppress your inner shopping ideas because of shyness in your pocket.

This is also why almost everyone is more willing to talk about feelings with rich people, because rich people can consume very freely, can live more chic, follow rich people, can have meat to eat, do not have to be poor, do not have to live a hard life.

Ang Lee is now a super rich man, looking at the whole world, people who are richer than Ang Lee are almost impossible to find, and there are still many ways for Ang Lee to make money, and there will be more and more wealth.

"Wine, sardines, ham, hehe! There are a lot of delicious foods! Yo, there are so many souvenirs, these clothes are not bad, they are made of Datang silk, and they are new styles. ”

Li An looked at these goods and spoke.

These are almost all specialties of the Rahman Kingdom, and if you don't bring some more, it will be a big loss, and this trip will be in vain.

However, the ultimate goal of the Datang railway line formulated by Li An is definitely to lead to the Rahman Kingdom, as the terminal of the railway, in the future, the Rahman Kingdom will inevitably usher in a round of prosperity.

After purchasing a sufficient amount of local products, Li An and his party planned to leave here and return to Chang'an City in the Tang Dynasty step by step.

Rahman was personally in charge of seeing him off, watching Ang Lee's fleet leave the port of Córdoba and sail into the distance.

Ang Lee's fleet needs to arrive in Gibraltar first, and then after a short rest, go to the ports in northern Egypt, maybe have to take a short rest in Benghazi and other ports on the way, but within a month, it will definitely be able to reach northern Egypt, and as long as the land route from Egypt to the Red Sea, Ang Lee can return to his steamship, after that, the sea voyage will be much more comfortable, after all, the ships provided by the Ottomans are too bad, no matter how much they are modified, they are not as comfortable as Ang Lee's own steamship.

The journey from Cordoba to Gibraltar was relatively smooth, and the fleet arrived in Gibraltar very smoothly without any strong winds and waves.

According to the previous agreement with Rahman, Gibraltar at this time already belonged to the Tang Dynasty and was the territory of the Tang Empire, and hundreds of soldiers from the port and nearby Rahman had all been evacuated, and part of the population of the port also left, while some of the people who were unwilling to leave here proposed to join the Tang Empire and become the common people of the Tang Empire.

Since these ordinary people really belong to Datang, Li An is not easy to refuse, otherwise, it will be chilling, besides, the whole port is not big, it is not small, the construction and maintenance of the port requires a huge labor force, and these remaining population can just be used as labor, which is very beneficial to the construction of the port in Datang, besides, the officials of Datang can also see that these people are indeed very ordinary people, there are no treacherous people.

All the soldiers and shipwrights were very tired from the journey, so after arriving in Gibraltar, they had to rest for a while before continuing their departure, otherwise the morale of the soldiers would be greatly affected.

After learning that Gibraltar had been assigned to the Tang Dynasty, the Tang officials stationed here began to measure and plan on the one hand, and had already started to build artillery towers in several dangerous locations for the defense of the port.

Although, the strength of the Tang Empire is there, and no one dares to provoke casually, but the most basic port defense must be carried out, otherwise, if it is attacked, the soldiers in the port will suffer heavy casualties, after all, it is unlikely that Li An will deploy too many troops in Gibraltar, which is far away from the mainland, and it will be about the same if he can deploy three or five hundred people at most.

With such a small number of soldiers, the pressure on defense must be very great, and in this case, it is very necessary to build fortifications, so that three or five hundred men and horses can play the effect of thirty or fifty thousand troops.

After all, after arriving in Córdoba, Ang Lee's Maritime Silk Road has been completely opened, and such an important moment, of course, needs to be celebrated, but Córdoba is the capital of the Rahman Kingdom after all, and it is not convenient to celebrate on other people's territory, and Gibraltar is already the territory of the Tang Dynasty, so it is very necessary to celebrate here.
