Li An doesn't have to think about anything at the moment, he just needs to sleep comfortably, although the task of this trip is important, but the difficulty is almost not much, after all, whether it is the Ottoman or the Spanish guys, the strength is relatively weak, and there is no strength to compete with the Tang Dynasty at all, especially the Ottoman guy, if it wasn't for the Datang selling him so many weapons, how could he pacify Egypt so quickly, and still have the strength to conquer the Quartet.

After the strength grows, people's ambitions will also become correspondingly bigger, and they don't know what their surname is, Ziyad was only a general of the Umayyad Dynasty before, and after the fall of the dynasty, he can honestly declare his allegiance to the small Spanish court, but after the strength grows, he immediately shows his fox tail, and actually calls himself the Sultan, and draws a clear line with the small Spanish court, which caused the small Spanish court to send troops to quell the rebellion, and caused the Ottomans to expedition to Spain.

Qi Yade has ambitions, and it is also a good thing for the Tang Dynasty to be able to break away from the small Spanish court, so that they will become two countries, and the power can be dispersed, but Qi Yade's ambition is a little too big, much bigger than Li An imagined, he not only broke away from the small Spanish court, but also expanded everywhere, and even wanted to destroy the small Spanish court in a fit of anger, so as to strengthen his own power, if the Ottomans really annexed Spain, then the fruits of Li An's painstaking management will be in vain, and this is what Li Ang cannot tolerate.

In Li An's view, the strength of the small Spanish court is weak, far less powerful than the Ottomans, of course, this is mainly reflected in the combat ability, if it is about national strength, the two sides should be about the same, both are relatively weak national forces, just because the Ottoman himself can fight well, there is an elite army under his command, so that the fact that the Ottoman strength is stronger than the small Spanish court, if it really fights, the consequences are no suspense, the army under the command of the Ottoman will inevitably be able to destroy the small Spanish court, As a result, the Ottoman force was too strong, which seriously damaged the interests of the Tang Empire.

Because the Datang Canal has not yet been built, you don't need to take a boat to Egypt from Canal City, you can just take a land route, and you can arrive at the back port town of Egypt within a few days and meet with the current leader of the Egyptian regime, Osman.

Because there is no real road on this road, the vehicles are relatively bumpy, fortunately, Ang Lee's car has a very complete shock absorption system, so sitting in it will not feel too bumpy, and those vehicles without a shock absorption system are more unlucky, and it is estimated that they can turn the soldiers' internal organs upside down.

There are still bumps, but they are not very big, this is the premise that Li An can sleep peacefully, from departure to camping, Li An has been sleeping, and has not woken up for a moment, until the vehicle has stopped, he can't hear the sound of the engine, and he can't feel the bumps, Li An slowly woke up.

The first time I camped in an oasis in the middle of the desert, there was a small lake, and there were some drought-tolerant plants around, and it looked like a good place to camp, but the heat was certain, after all, this is the heart of the desert, and if you want to cool down until night.

The desert is full of sand, and the specific heat of the sand is relatively low, that is to say, the heat absorption of the sand is very fast, but the heat dissipation is also very fast, which leads to the very hot in the desert during the day, and once it is at night, the desert will be very cold, in the desert, you can experience the four seasons of spring, summer, autumn and winter in one day, which is also a good experience!

In order to speed up the march, Li An stipulated that it should take seven hours a day to travel, and the time to camp was only five hours, so as soon as the army stopped, the soldiers hurried to set up tents and prepare various foods.

It only takes a few days for the army to reach the port towns of northern Egypt, but the food prepared by the logistics is doubled to ensure the absolute safety of the journey, and even a lot of fresh water is prepared, and there is a lot of water to replenish along the way.

Because in the desert, water is the most important resource, not only people and animals need to drink, but also the engines of various vehicles also need water to cool down, otherwise, it is easy to fail.

When it was dark, the food was all ready, the soldiers began to eat and drink, and many soldiers took off their armor and even took off their underwear, after all, it was too hot, and it was a little unbearable to wear armor, and even ordinary clothes were very uncomfortable to wear.

"Big brother, the climate in this desert is so hot, even the wind blowing on the body is hot, and the war horses are about to be too hot to stand it."

Li Feiyu was shirtless, drinking iced black tea, and complained at the same time.

"What's more, in the second half of the night, people can wake up frozen with quilts, hot during the day and cold at night, what the hell is this weather."

One of the subordinates spoke.

In fact, on the last trip to Maia City, they had already complained once, of course, this is not to settle accounts with anyone, but just a feeling, a feeling of dissatisfaction with the environment.

Just like the canteen food in later generations is not delicious, employees will complain when they eat, basically they will complain once they eat, and even form a habit, when they eat canteen food, if they don't vomit, others will not adapt, and they will not adapt to it, as if something is missing.

In fact, this can be regarded as a kind of venting, by venting dissatisfaction to relieve pressure on yourself, so that you don't have so much pressure.

Li An smiled and said, "Let the soldiers put the quilt by their side, and when they feel cold, they can cover the quilt whenever they feel, and don't freeze it." ”

For the soldiers under his command, Li An has always been very concerned, and it is no problem to describe Li An as a soldier like a son, and Li An is such a person.

"Big brother, there is so much sand here, if you build a glass workshop here, you will definitely be able to produce a large amount of glass, and the cost can be reduced to a minimum."

Li Feiyu looked at these sand dunes and spoke.

Li An smiled: "The cost of sand is gone, but the cost of labor and transportation is too great, even in Chang'an City, the cost of sand is not much, it is expensive labor and transportation, of course, there is technology, and only the cost of sand itself is negligible." ”

Obviously, the cost of sand is not the main cost of making glass, there is sand in the desert, the cost is almost zero, but the living conditions in the desert are too difficult, if you open a glass workshop in the desert, no one will be willing to do it without giving more wages, and this raises the labor cost, and the manufactured glass also needs to be transported, which is a big cost, so it is not cost-effective to make glass in the desert, it is better to make glass in a place with good scenery, In this way, craftsmen can also have a better production and living environment.

At present, only Ang Lee has fully mastered the related technology of glass, and the craftsmen under his command have only mastered one part of it, and cannot form a complete industrial chain, and in order to prevent the leakage of technology, Ang Lee will not allow the construction of glass workshops abroad, otherwise, this technology will leak out sooner or later, and then Ang Lee's secret money-making technology will be gone.

Don't use chicken soup for the benefit of the people of the world to influence Ang Lee, let Ang Lee give the technology to the world for free, this is absolutely impossible, Ang Lee has not yet had such a high consciousness, and even, give this technology to Datang businessmen for free, Ang Lee is reluctant, if it is really completely leaked out, Ang Lee will still make fart money.

And because of the special relationship between Ang Li and the Tang Dynasty, the high-quality glass and finished products produced are all given priority to the imperial court, so the Tang Dynasty will not intervene, and China has a tradition since ancient times, that is, it does not force people with knowledge and technology to make the technology public, and basically it will not be made public.

Because people are selfish, they are unwilling to tell others the secret recipe they have worked so hard to study, and this is true for those who read, those who have skills, the gentlemen who teach, and everyone else.

It is for this reason that many technologies in ancient times were lost, because many technologies were passed down from father to son, and once they were lost, they would be lost.

Of course, Ang Lee won't think about the future, as long as he is comfortable now, it is enough to earn endless money, and it is a waste of time to think about what he is doing in hundreds of years and thousands of years.

For the sake of self-survival, Li An needs to hand over part of the technology to the imperial court, keep some of the technology for himself, and share some of the technology with other powerful people, so that everyone can be satisfied.

For example, Yang Zhao's women's underwear and Hushu Bao were all invented by Ang Lee, and the technology was transferred to him free of charge, so that this old boy made a lot of money, although his reputation may not be very elegant, but Yang Zhao is not stupid, he will not directly manage these two industries, but hand them over to his trustworthy doglegs, he himself can be regarded as the boss behind the scenes, and he will not run to the workshop when he is usually fine.

But the nobles in the capital are not fools, which boss is whom, they are all clear, everyone knows that the boss of Hushubao and the boss of women's underwear are Yang Zhao's people, so these two industries are undoubtedly Yang Zhao's, but because this is a legal industry, it can also serve aristocratic women well, so, in addition to laughing at it in private, I don't think there is anything bad, and even buy some in private, and when I go to the Qinglou to be happy, I give it as a gift to the little lady in the Qinglou to please the little lady, Let the little lady serve herself better.

The decent style of aristocratic children will also secretly buy some, go back to give them to their wife, and then listen to the sweet laughter and scolding of the lady, and take the lady in their arms, in short, many people say that it is not good, but they like it very much, and they will still take care of Yang Zhao's business, which is also the reason why Yang Zhao's voice is excellent.

From ancient times to the present, a woman's money is always the best to earn, because women are born vain and love beauty, like to compare with others, and like to enjoy life, and the two properties that Ang Lee gave to Yang Zhao are undoubtedly the ones that can touch the hearts of women the most, so making money is absolutely impossible to run.

Maybe Yang Zhao occasionally complains about Ang Lee, and what he gave him is an industry that can't be put on the table, but when he looks at the account book every month, he only has gratitude left in his heart, because this money-making is really powerful, much stronger than ordinary industries, and what Ang Lee gave him is an industry that can make a lot of money, so how can he have an opinion?

When Ang Lee went south to build the Maritime Silk Road, he would naturally spread some of the technologies, but it was impossible to spread the most profitable and core technologies, some of which were suitable for promotion to all mankind, and some of which were suitable for keeping for himself, and the two could not be mixed.

For example, the low-level technology of collecting iron ore and producing concrete is completely unnecessary, because the profits in these aspects are not high, but the demand is very large, if this thing also restricts the technology, it will seriously affect the construction of the Maritime Silk Road, resulting in a lack of resources for construction.

In other words, only by more people mining iron ore and producing cement and concrete construction resources can the price of these resources be better reduced, which is conducive to the construction of the Datang Maritime Silk Road and the faster and better development of the Datang Maritime Silk Road.

The large-scale infrastructure construction of Datang is inseparable from a large number of steel and cement resources, and it is because Li Ang is very generous to disclose all these technologies that a large number of nobles and powerful people to produce these raw materials, thereby reducing the price of building materials on the market, so that the Tang Empire can carry out infrastructure construction very smoothly and promote the rapid development of industrialization.

The same is true for the opening of the Maritime Silk Road in the south, cement and steel technology, Li An is very generous to the Tang merchants who do business in small countries, so that they can mine resources in these small countries, so as to promote the construction of the Tang Dynasty overseas.

There are soldiers patrolling the camp at night, so the soldiers can rest very at ease, without worrying about danger, and there is no danger in the desert itself, large beasts have no way to survive in the desert, and small animals pose no real threat to people, as for the enemy, it is definitely non-existent, no one dares to go against the Tang soldiers, unless they don't want to live.

After a night's rest, early the next morning, the Datang team continued to march to the hinterland of Egypt, they had to arrive at the coastal town in northern Egypt as soon as possible, and chatted with the Ottoman about life, so that he could understand how many catties and taels he had, what he should and should not do, what he could get and what he could not get.

A few days later, Ang Lee's 3,000 men and nearly 1,000 vehicles arrived at the port town of northern Egypt and were personally received by Osman outside the city gates.
