The weapon tycoon who traveled to Daqin

Naofumi got up very late. Last night, Naofumi was busy until very late. Mainly on the printing side. The emergence of paper gave rise to the downstream industry of printing. Due to Naofumi's vigorous pointing out, especially the foundry workshop provided a lot of manpower and material resources, and even

Sacrifice the time of casting cannons to carve those small bronze fonts. The quantity is very huge. One hundred fonts need to be cast. This is what Naofumi put forward very early. Because

, it is impossible not to reuse a word. Especially after the emergence of paper. The current output can only provide Qin's government, wealthy people, and bullets. It cannot even be exported. For this reason, Shangwen has clearly stipulated.

A large number of factories were built. The factory site was chosen in Chang'an County in the southeast of Xianyang. This was the center of the Han Dynasty in later generations, but it is not yet the center because a super empire is gradually rising.

In terms of printing, there are some unexpected inventions. There is a rotary (circular relief) printing press. However, the overall shape is not a circle, but a hexagonal shape. On one side of the hexagon,

Two rows of movable type can be arranged, and then rotated and printed sequentially, which can speed up the printing speed. This invention greatly promotes printing. Naofumi immediately issued a technical patent certificate for this invention in person, and spent one hundred gold on it.

Encouragement. This greatly stimulated all printers.

The reason why one hundred gold is used as an incentive is because with the emergence of printing, a large number of printed matter can be printed. These printed matter include newspapers, magazines, and books. Newspapers and magazines are powerful tools for controlling public opinion. And books can record ancient thoughts.

It greatly protects the continued development of culture. This is a big thing that is beneficial to both ancient and modern times. With books, libraries can be established. With libraries, no one can resist the cultural field of Qin.

Especially newspapers and magazines. This is an important guide for public opinion. You must know that public opinion at this time was largely in the hands of various masters in the Warring States Period, especially the hands of Confucianism. The emergence of newspapers and magazines will effectively promote the spirit of the legal system. It will greatly

Impact on the public opinion-guiding role of Confucianism.

However, the printing speed is still relatively slow. After all, the paper is tight, and there are cutting and binding processes. The printed training syllabus and basic knowledge manual of the Space Force that Naofumi requested will not be available until tomorrow at the earliest.

Naofumi inspected the arsenal as usual. This time there were some surprises in the arsenal. The first was a four-wheeled carriage. When Naofumi sketched the carriage, he did not mark the design of the shock absorber spring. However, Daqin's craftsmen, stimulated by knowledge and technology patents, extremely

The big ones used their ingenuity and discovered the wonderful function of springs in the bolts of muskets. Together with the drawing machines, they mass-produced some different sizes.

Iron wire. They began to make shock absorber springs according to their own requirements. When producing shock absorber springs, specialized fitters were separated. This was a bit surprising to Naofumi. Because the prototype of the fitters that Naofumi saw before only appeared in production.

On the barrel, and on the bolt. Unexpectedly, a shock absorber spring directly separated the fitter. And the division of labor became more and more detailed. The speed of production became faster and faster.

The four-wheeled carriage has a very good steering system, and the use of shock absorber springs ensures that the overall body of the carriage is in a stable state. This carriage is specially used for cargo, and is pulled by two horses. It is made of iron

Wheels. The wheels are not cast as a whole, but forging technology is used. This is a brand new attempt.

After Naofumi tried the horse-drawn carriage, he believed that this kind of four-wheeled carriage could be manufactured in large quantities. At the same time, it could also be used as a new transportation platform to make different types of carriages. For example, carriages specially designed for people to ride on. Naofumi proposed this point

own opinions.

After seeing the horse-drawn carriage, another means of transportation attracted Shangwen's attention. After returning from the north, Xi Lao secretly studied bicycles. In particular, he simplified the process of making bamboo bicycles. The first batch of bicycles quickly went to Xianyang.

streets and alleys. But problems soon emerged.

The first is that the load capacity and durability of bamboo bicycles are very poor. Those who buy bicycles are farmers, handicraftsmen, or small traders who go to the city. They have a large amount of goods that need to be carried. And they also need to carry a lot of goods.

It takes a long distance to get into the city. Therefore, bicycles are soon abandoned by a large number of people.

The second is the material of bicycles. Xi Lao still stubbornly believed that bamboo products can be used in large quantities. However, as a large number of bicycles were returned to the factory in large quantities, he finally realized the upgrade of materials.

This time the material is made of iron. The overall design adopts an iron pipe. Originally, iron pipes were specially used for gun barrels. However, with the development of hair tube and perforation technology, the number of gun barrels began to increase.

This is due to the improvement of drill bits. Machine tools also used steam engines and began to be improved into single-axis automatic lathes. These inventions led to the further acceleration of the production of gun barrels. Coupled with the application of thread technology, bicycles began to be made of iron.

The load capacity and durability of the original bicycle have been greatly improved.

However, it is worth mentioning that at this time, there were still no tires, because Qin State did not have rubber. Rubber could only be found in tropical and subtropical areas. Obviously, the latitude of Qin State was a bit high. Moreover, bearings had not been invented at this time.

The main reason is largely due to the extreme backwardness of the chemical industry and the lack of refrigeration equipment. Especially the discovery of refrigeration chemicals. It seems that this must be improved.

At the same time, another invention of the Qin State was in progress. That was the steam locomotive. This was specially instructed by Shang Wen. A large amount of money was invested in its research and development. Along with this project, there was also the production of a hot rolling mill.

Mainly due to the manufacture and development of steam engines. Since the improvement of steam engines, the improvement work of steam engines has been carried out. Especially the advanced invention of turbines. All this takes time.

It only took a few days, one invention after another. And many projects are also in full swing, especially tractors. And tractor-related equipment are being developed. In particular, the work of making crawler tracks is being carried out on a large scale.

Improvements are in progress. However, Naofumi feels that it will happen sooner or later. First of all, the carriage technology uses shock absorber springs, and the improvement of train wagons is ahead of schedule.

Take a step forward. The crawler tracks were originally derived from bicycle chains. Especially with the development of bicycle technology. With bicycle technology at the forefront, the work process of the crawler tracks will be much easier. The entire system of the train is still being explored, mainly due to the lack of steam engines.

Because some machine tools are not perfect enough, some parts, especially key parts, cannot be machine-made. This is a factor that limits the development of steam engines.
