Li Ke thought about it, and first selected a few sets of books from it, such as books on spinning and weaving, starting from the most basic loom spinning machine, to the more distinctive Jenny spinning machine in history, and then to the spinning machine driven by the steam engine.

The steam engine is not needed, but the Jenny spinning machine is enough, and in the Tang Dynasty, this is a big killer! Originally, silk and cloth were the biggest advantages of the Tang Dynasty!

In addition, a set of flying shuttle looms was naturally taken out, including a Jacquard machine specially used for color production, these are the most basic machines, and there is an upgraded version of it later, but the upgraded version Li Ke does not need it for the time being.

Whether it is ancient or modern, if you want to make money, clothing, food, housing and transportation are the most basic, and even more so in ancient times, for ordinary people, they can only care about these four things.

In terms of eating, in addition to preparing relevant poultry and livestock breeding books, Li Ke is also selecting and breeding.

It's a pity, I don't know if there are any other warehouses, there is grain storage in this strategic reserve warehouse! Naturally, it also includes growing food! Moreover, Li Ke knows that the grain stored in the strategic reserve warehouse is not the kind of grain that can only be grown for one season on the market.

The seeds that can be bought on the market can only be planted for one season, which is specially bred by the seed company, but the strategic reserve is not the same here, the seeds stored here can be repeated and retained, although its yield is certainly not as good as the market, but its biggest advantage is that the follow-up can be retained, and will not degrade rapidly.

The point is that there are many seeds that Datang does not have, such as corn, potatoes, sweet potatoes, etc.

However, it doesn't matter if you can't get these seeds for the time being, the existing crops can be scientifically selected and bred, and we will talk about it first.

This warehouse for storing books is huge, and it is divided into many different compartments, Li Ke didn't look at it completely, it took too much time, and he didn't need a lot of high-end knowledge.

Li Ke simply walked out of this door and continued to walk along the corridor, he wanted to see what else was stored in this underground warehouse.

Soon, a second warehouse door appeared in front, Li Ke opened this warehouse door, and when the contents were imprinted into his eyes, Li Ke was stunned again, and the things here were still beyond his expectations.

What is stored here is paper – .

That's right, paper.

The only difference is that these papers are used to make money.

It's all neatly sorted and packaged here, and the paper in the entire warehouse, Li Ke doesn't know how much currency can be printed, but obviously this thing is really useless to him, at least not for now.

Li Ke also looked at several other warehouses, and there are only four warehouses that have been unsealed in the passage at present, in addition to books and currency-specific paper, the remaining warehouse is currency-specific ink, and a warehouse should be disassembled with printing equipment.

The passage is still stretching forward, but it is shrouded in fog, and it is estimated that it will take time to unblock.

After packing up his things, Li Ke directly chose to leave this space, and in a flash, the surroundings turned into the scenery on the carriage again, but Li Ke had a few more sets of books in his hands.

However, these sets of books cannot be directly shown to craftsmen, not to mention the paper and printing methods, that is, the contents are written in simplified characters, and it is estimated that they may not be able to understand them, so they can only guess the meaning.

Li Ke simply disassembled a few books that were temporarily ready to be taken out inside, took out all the illustrations inside, and then directly asked the craftsman to make a part of the drawings according to the drawings.

Don't underestimate the craftsmen of this era, in fact, many tools of later generations have taken shape in this era, and carpenters are the best among all craftsmen.

Back at the Shu Palace, Li Ke directly asked Tian Meng to call the carpenter in the mansion and the person in charge.

There are a total of 27 people who came, three generations of master and apprentice, three masters, six backbone carpenter masters, and the rest are the third generation of apprentices.

"I've seen Your Highness!" After Li Ke arrived, everyone immediately saluted at the same time, and their eyes were full of worship.

The loyalty of these people is undoubted, and their whole person also belongs to Li Ke as the master legally.

"Can you understand this thing?" Immediately, he handed the drawing of the disassembly of Jenny's spinning machine to the three masters who took the lead.

The three masters immediately took the paper in Li Ke's hand, and when they got the paper, they were immediately a little surprised, the quality of this paper is too good, not to mention, it is so tight, and it is smooth and not rough, and it is very fair.

But knowing the above content, they were even more amazed, the pattern on it is extremely exquisitely depicted, the point is exquisite, how can such a thin black line and that extremely delicate small print be written?

It's just that they don't know this word well, but focusing on the pattern, they immediately realized that this should be a drawing of an item, but the method of this drawing is unheard of, but they can see its essence at a glance!

The person who can invent this method of drawing is an absolute genius! It's so important for the legacy of their craftsmen!

"Dare to ask Your Highness, who made this picture?" A master really didn't hold back.

"This is confidential, you don't have to worry about it, I can tell you, you can make similar patterns in the future, and even you masters may publish a book and pass it on!" Li Ke said with a smile.

He has been living in this era for eight years, and he knows all too well what people in this era value most.

Sure enough, when Li Ke said that they were all qualified to publish a book and set up a biography, the three masters were so excited that they almost knelt down on the spot, if it weren't for the fact that they deeply remembered the rules of Li Ke's mansion and were not allowed to kneel, it is estimated that they would have knelt a long time ago!

"Yes! I wait for you to understand, Your Highness, we can understand this picture, although the item is exquisite, but it is not difficult to make it, but this machine seems to be a spinning machine? "A master can see at a glance what this machine does.

"Yes, spinning machines! This is my research and invention, and it can increase the spinning efficiency by sixteen times now! Li Ke said with a smile.

Sixteen times?! Everyone present was shocked! Like these master carpenters, of course they understand spinning machines, because most of the spinning machines need carpenters to finish, and there are even pure wood spinning machines.

Datang's spinning machine is still in the initial stage, that is, one person spins a thread, and there are not too many large-scale spinning firms, and many yarns are spun into yarn or silk thread by ordinary people at home, and finally sold to merchants.

Only very large-scale trading houses have the point of centralized spinning, but basically one person is responsible for spinning a yarn.

But the modified spinning machine, based on the Jenny spinning machine, can spin up to sixteen threads per person at a time! Whether it is manpower, material resources or efficiency, it is a great improvement!

In the era of Datang, when silk silk can be used as currency, this is a proper money printing machine!

In fact, if it weren't for the limitations of the materials of this era, such as the difficulty of making iron gears and rotors with very fine polishing, if they were replaced by wood, they would not be as silky as iron rollers, and the spinning machine could spin hundreds of yarns at once!
