Li Sheng didn't sleep all night, and taught the usage of the sextant directly to these disciples overnight.
Once you do this...
The sextant is a scientific instrument. The use of this thing depends on the prerequisite skills, that is, whether basic mathematics such as trigonometric functions have been learned, rather than proficiency. Therefore, it can be taught even at night, and then... strive for more as much as possible
Give them more time to review.
Secondly, it is because Li Sheng's fleet has been equipped and equipped, the sailors have been trained, and the expedition is about to begin.
For merchants—whether they are doing business for themselves or for the country—ships are the same as the military. In fact, if they are not used, they will lose money.
Being idle means losing blood, so Li Sheng must set off as soon as possible.
Secondly...
Li Sheng was already tired of waiting for when rubber would be available, as well as the improved rice varieties and iron ore and coal mines from "Dongnan Diao".
Without resources, this is nothing but industrialization.
Although Datang's industry has not yet started, it is best to use resources within China to start as soon as possible, but if you think carefully...
The forces surrounding Datang, currently...
The Turks can basically be considered as having been captured.
Other small tribes are not of concern for the time being.
The big forces include Goguryeo in the north and the subcontinent in the extreme south, including Tianzhu, Zhunian and other countries.
These forces, let alone industrialization, do not even have relatively high-end semi-handicraft products such as grenades, so there is no need to be nervous.
But Li Sheng knew that once something like technology comes out, it is only a matter of time before it spreads from the country that developed first to the country that developed later.
Considering that Tianzhu and Zhuchaan in the recent period seem to be very developed in the history books, and Goguryeo was able to confront the Tang Dynasty for a long time, it is obvious that there are powerful characters in the country, and the politics are clear and the military is well-equipped.
In this case, the natural way to get resources is to do it as quickly as possible...
By then, if someone unknowingly develops thermal weapons such as grenades, we, the Tang Dynasty, will be in trouble.
It's definitely not going to be a big trouble, but...
The arms race in later generations is essentially nothing more than an industrial race. This will definitely happen as quickly as possible...
Li Sheng arranged courses for the boys and girls, and then quickly sent a message to call a few friends in Chang'an to help ask how the steel factory in Chang'an was doing...
Well, Li Sheng only recently found out that some money buffs like Lao Li and Lao Wei somehow managed to acquire shares in several government-run steel plants in Chang'an!
In principle, Li Er will not open this share to the public. This is also Li Sheng's suggestion...
At the beginning of the establishment of industry, you can make a lot of money with any invention or creation, but after you make money... not always every factory owner is willing to organize manpower and material resources to tackle new technologies. Compared with this kind of complicated work,
For most factory owners, especially in China, after accumulating a large sum of money, their first choice is to buy land.
Then the Tang Dynasty also had a hammer industry, so Li Sheng's suggestion to Li Er was that in principle...
Only difficult projects that the imperial court could not handle were left to wealthy private businessmen to participate.
How is it possible that the current imperial court has technical barriers that require private forces to break through...
Could it be that Li Er has some new ideas of his own?
But the problem is that the people don’t have the ability to make any technological breakthroughs... Or is it that Lao Li also has great powers and knows some strange people or top-notch craftsmen...
After all, the national strategic technical barriers that need to be solved these days are basically created by ourselves. The main bottlenecks are all kinds of materials that may seem very basic to later generations, but in this period, there are really only some materials such as rubber, which is a process.
Problem.
If the processing accuracy is not enough, a large number of projects can only stay on the drawings.
In general, Li Sheng was very puzzled when he learned that Lao Li actually had shares in the imperial steel factory, but after thinking about it, it didn't seem completely unreasonable, so he just let it go.
As for what to do...
Naturally, it is Li Sheng's order. In addition to marine steam engines, land-based steam engines, and...
The steam engines used in airships are all from the same batch.
This made Li Sheng very grateful that China was large enough and had a large enough population, even after hundreds of years of war.
Because the country is large enough and has a large enough population, no matter what project it is, it can always be easily scaled up and the cost spread out...
If the steel plant has only been operating on a small scale so far, then it is conceivable that it is impossible for Li Sheng to have such an operation as "customizing steel parts with precision that meets standards".
If you don't have a large scale, you can't raise a high level of blacksmith craftsmen, and you won't be able to keep up with the accuracy.
And because it is small in scale and has to benefit the people, it is impossible for this steel plant to make a profit. The operating costs must be extremely high, and things are naturally ridiculously expensive.
But the good thing is that Chang'an's steel plant has now accumulated a certain amount of accumulation, so these are no longer problems.
After writing the letter and sending it by express delivery, Li Sheng continued to persuade people, and then approached the steel factory in Hangzhou.
In principle, during this trip to the sea, Datang would not directly conquer any foreign country. Everything would be in the form of exchange and trade.
Naturally, the first batch of things that Datang wanted to export were all kinds of exquisite steel products.
Needless to say, the value of swords and swords is huge. In this era, each one is worth a lot of money.
The steel utensils produced by the steel factory are as exquisite as the various gold and silver utensils used by the noble families of Chang'an, and they are also good materials for export.
Of course, in Li Sheng's view...the most critical advantage of these export products is that they are all industrial products.
Its material cost is always extremely low in nature, and this extremely low cost cannot be replicated by any country in the world...
With this understanding, Li Sheng could easily recall how the British and Americans in later generations made their fortunes.
therefore……
Naturally, the ship cannot be empty during this voyage - there is depreciation but no profit. This is more of a blood loss than being idle. It can be called a loss of blood and a loss of blood...
Of course the goods must be filled.
In addition to goods, there are other things that are also essential.
After arriving at Zhongzuo So, we still have to set up camp——
Li Sheng had seen the big cockroaches and big rats in the South for a long time. Although each ship brought mascot cats and insecticide powder this time, it was definitely impossible to take everything into account.
So when setting up camp, of course it is best to use cement, which you also need to bring.
Even if you can't bring too much, you probably only bring cement powder, use cement in some key parts of the building, and use concrete mixed with sand, soil and gravel...
But the amount is still not small, it will probably take up about a ship.
In addition to cement, twelve large ships went out to sea. Of course, this saint-like posture also had to prepare enough food and grass...
