At night, there was a small moon in Shanghai. By April, it was approaching the rainy season, and the air in Shanghai also became wet. The wet sea breeze blew slightly, and Shanghai was immersed in the red lights and wine.

Lying on the bed, my consciousness had already entered the all-in-one machine. To be honest, today's harvest is more than the previous ones in Shanghai.

Military ships are the pinnacle of technology in this world. Even if they are just some inequality second-rate, even third-rate and fourth-rate warships, the technology contained in it is far more powerful than civilian technology.

In one day, Yang Yuanzhao copied 12 different steam engines, from the 1895 model to the 1905 model, especially the 1905 model, used on a lightning strike ship. This lightning strike ship was just introduced last year and used the British steam engine in 1905. Although it is not a steam turbine, it already represents the cutting-edge technology of this era, at least the highest technology of the UK.

Because of the more powerful steam engine, the UK has been very perfect for steam turbines. The new dreadnought is derived from the powerful power of the steam turbine. However, the German steam engine has been increased to a level of 4 expansion, but the gap with the steam turbine is getting bigger and bigger. Next year, when the Caesar-class construction began, Germany also adopted steam turbines. This change means that ordinary steam engines are completely out of date. Therefore, Britain and Germany almost unanimously relaxed the restrictions on steam engines. This lightning strike ship of a three-inflat steam engine entered China under this situation.

This was something Yang Yuanzhao never expected. In his opinion, except for the Haiqi, there were at most several other warships with the word "Sea" and were all made by the same group at the Armstrong Shipyard in the UK. Even if there were some changes, they were similar. They all appeared more than 10 years ago, but they did not expect to be caught on a small boat.

The steam engine, even the three- or even four-expansion steam engine, is not very high in terms of the 21st century perspective, but machinery, especially steam engines, are extremely precise machinery and equipment. Any slight deviation will cause huge problems. Even if Yang Yuanzhao himself understands that if he does not make it himself, it will be more difficult to complete it. The tractor he took for granted before was because he failed because there was no experiment.

The same is true for steam engines, especially high-end steam engines such as three-expansion or even four-expansion. Yang Yuanzhao estimated that at least half a year or even one year of research, it would take at least half a year to get a complete steam engine, and it was a relatively basic product.

But now it is different. I directly obtained the two-axis steam engine from 12 years ago, and a batch of different types of two-axis engines. It can be said that the whole system has been improved. The most important thing is to have a three-expansion steam engine, so that both the high-end and low-end ones are already available. With Yang Yuanzhao's research strength, it is easy to take out samples of the four-expansion steam engine based on this. Although in this era, the four-expansion steam engine has lagged behind, and these steam engines are no longer used on the new battleships, but instead use steam turbines.

In this world, the pulse of industrial development is constantly jumping. Starting from Watt's invention of the steam engine, the first industrial revolution and the second industrial revolution are all related to power. Such a steam engine has a decisive impact on many things in Yang Yuanzhao's next step.

In addition to the three-expansion engine, Yang Yuanzhao's other gains were also huge. More than 20 ships were warships. The most basic ones on the warship were weapons, from the lowest 30mm cannon to the 203mm heavy cannon, especially those cannons, which made Yang Yuanzhao have a different choice.

The Chinese army has always had relatively poor firepower, with many troops and almost no artillery.

On the one hand, China's weapons are relatively backward. When all imported, foreign countries can only use whatever they sell to them. Even things like artillery bullets need to be imported. On the other hand, it is related to China's harsh traffic environment. There are almost no modern roads and railways. Cannons can only operate on muddy land and use the help of pulling horses. The 75 cannons can be counted as heavy artillery and cannot be passed in many places.

Among Yang Yuanzhao's ideas, mortars should be the best choice. In this era, mortars have not been invented, but seamless steel pipes have existed. However, Yang Yuanzhao is not a military expert. To a certain extent, it is even more difficult to develop mortars. He is preparing to copy the drawings in the first battle or after the mortars appear. Unexpectedly, after seeing this batch of 30 cannons and 47 cannons, he gave him new ideas.

As small caliber firepower on warships, 30 cannons and 47 cannons are generally self-defense firepower or near-defense firepower, mainly torpedo protection, but in the army, they can become suppressing firepower. If the power of 30 cannons and 47 cannons is increased and the explosive power of the shells is strengthened, it is enough for ordinary support firepower of the army.

However, ship-used machine guns are different from ordinary army gunfire. Ship-used 30 cannons and 47 cannons are generally in two-way connections, because on ships, 30 and 47 cannons do not need to consider weight, but on the contrary, for the issue of firepower stability, it will be aggravated a lot. According to the drawings copied by Yang Yuanzhao, the weight of the double-way 30 cannon is about 700 kilograms. Yang Yuanzhao will modify it to remove some unnecessary things, and after reducing the weight, it will change from a double-way to a single-way connection. In this case, as the army's firepower, it is enough to be used.

This change is very slight for a cannon, and it only took less than an hour. The ship's all-steel bracket was changed to an ordinary triangular bracket, and it can be disassembled. The part of the barrel cannot be disassembled. However, the gun machine and some unimportant parts can be disassembled. In this way, the 30 cannon can be divided into 7 different parts. The largest part weighs no more than 90 kilograms. Although it is still very heavy, for the previous 75 cannon, the weight of 1,300 kilograms can be definitely much lighter. A strong soldier can carry it and travel for a short distance, and the total weight will not exceed 250 kilograms, which is absolutely lighter.

As for the 47 guns, initial improvements have been made, with a weight of no more than 400 kilograms. Unfortunately, the 47 guns are a little bigger. Yang Yuanzhao's division is not thorough and can only be divided into three parts. The heaviest part exceeds 200 attacks. Yang Yuanzhao still gave up the idea of ​​division. It is not difficult to use a horse to act with a pull-up horse. After the wheels are modified, a horse can be easily pulled up. Compared with the heavy 75 guns, it is much stronger.

After setting up 100 30 and 47 guns to be produced continuously, Yang Yuanzhao began to consider what happened after leaving.

After a month, Yang Yuanzhao's trip to Shanghai was a complete success. If there is anything missing, it is about chemical machinery and equipment. This is also a helpless thing. The whole world, the era of chemical engineering, is still cutting-edge technology. At least for China, there is no market. China's chemical industry will probably not have the Hou's alkali production method until more than ten years later, breaking the breakthrough of China's chemical industry zero.

Chemical industry, especially heavy chemical industry in chemical industry, can be said to be the foundation of industry. In the future, colorful products are basically derived from chemical industry and heavy chemical industry. Three acids and two alkalis, each of which plays an important role.

However, in addition to the omissions in chemical industry, other basic industries are complete. In the eyes of Yang Yuanzhao in his later generations, especially from the Shanghai Navy, he obtained a large number of advanced steam engines. As long as some materials are replaced and they are turned into small steam engines, they can provide strong and stable power for the factory, so that no matter what factory it is, it will have extremely high efficiency.
