At night, in the evening of Shanghai, it was a small moon, and in April, it was close to the rainy season, and the air in Shanghai became humid, and the wet sea breeze blew slightly, and Shanghai was immersed in a bright light.

Lying on the bed, the consciousness has already entered the all-in-one machine, to be honest, today's harvest is more than the previous harvest in Shanghai in a month.

Military ships are the pinnacle of science and technology in this world, even if it is just some second-rate, or even third-rate or fourth-rate warships, the technology contained in them is far stronger than civilian technology.

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

Because of the more powerful steam engine, Britain dedicated to the steam turbine, has been very perfect, the new dreadnought, is derived from the powerful power of the steam turbine, but the German steam engine has been vigorously improved to 4 swelling of the Cheng dù, but the gap with the steam turbine is getting bigger and bigger, to next year, when the Caesar class began to build, Germany also used the steam turbine, this change, on behalf of the ordinary steam engine is completely outdated, so, Britain and Germany almost unanimously let go of the restrictions on the steam engine, It was only under this circumstance that such a lightning strike ship with a three-expansion steam engine entered China.

This is Yang Yuanzhao did not expect at all, his own naval fleet, in his opinion, except for a sea prayer, at most several other warships with the prefix of the sea, they are all the same batch of Armstrong shipyards in the United Kingdom, even if there are some changes, they are all the same, they all appeared more than 10 years ago, but I didn't expect to catch it on a small boat.

Steam engine, even if it is a three-swelling or even four-swelling steam engine, from the perspective of the 21st century, the technology is not very high, but the machinery of this kind of thing, especially the steam engine, is extremely sophisticated machine equipment, any slightest deviation, will cause huge problems, even if Yang Yuanzhao himself understands, if he does not personally make the steam engine, if you want to complete, this is more difficult, before he took it for granted, it is because there is no real yàn, this will fail.

The same is true for steam engines, especially high-end steam engines such as three-expansion or even four-expansion, as far as Yang Yuanzhao estimates, it takes at least half a year or even a year of all-out research to get a complete steam engine, and it is a relatively primary product.

But now it's different, directly obtained the two-shaft steam engine 12 years ago, and a number of different types of two-shaft engines, it can be said that the whole system has been improved, the most important thing is that there is a three-expansion steam engine, so that the high-end and low-end are already there, with Yang Yuanzhao's research strength, it can be inferred according to this, it is easy to come up with a sample of the four-expansion steam engine, although in this era, the four-expansion steam engine has been backward, and the new battleships have no longer used these steam engines, and instead used 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, the second industrial revolution, all have something to do with power, so the 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 are also very huge, more than 20 ships, all of them are warships, on the warships, the most basic, is the weapon, from the lowest 30 mm cannon, all the way to 203 mm heavy artillery, almost everything, especially those cannons, so that Yang Yuanzhao has some different choices.

The Chinese army has always been relatively barren in firepower, with a lot of troops, almost without any artillery.

On the one hand, China's weapons are relatively backward, and under the condition that all imports are imported, what foreign countries sell to them, they can only use anything, and even shells and bullets need to be imported, on the other hand, it is also related to China's poor traffic environment, there are almost no modern roads and railways, and artillery can only operate on muddy land, with the help of horses, and the 75 guns can already be counted as heavy artillery, and they are impassable in many places.

In Yang Yuanzhao's thoughts, mortars should be the best choice, in this era, mortars have not yet been invented, seamless steel pipes are available, but Yang Yuanzhao is not a military expert, a certain process dù above, research out mortars, which is more difficult, itself he is preparing, to the First World War, or after the appearance of mortars, to copy the drawings, unexpectedly, saw this batch of 30 machine guns and 47 machine guns, and gave him new ideas.

30 cannons and 47 cannons, as a small-caliber firepower on warships, are generally self-defense firepower or close fire resistance, mainly anti-torpedo, but in the army, they can become suppressive firepower, if you increase the power of 30 machine guns and 47 machine guns, strengthen the explosive power of shells, as the army's ordinary support firepower, it is enough.

However, the naval cannon is different from the ordinary army gun, the ship's 30 cannons and 47 cannons are generally 2 joints, because on the ship, the 30 and 47 cannons do not need to consider the weight of the problem, but in order to stabilize the firepower, it will be aggravated a lot, according to the drawings copied by Yang Yuanzhao, the weight of the double-linked 30 cannon is about 700 kilograms, Yang Yuanzhao will make some modifications to it, remove some things that are not very needed, and after reducing the weight, it will become a single one from a double one, in this case, As the firepower of the army, it is already enough to be used.

This change, for a gun, is very slight, it took less than an hour, the all-steel bracket for the ship, was changed to an ordinary triangular bracket, and it can be disassembled, the part of the gun barrel can not be disassembled, but 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 of the weight does not exceed 90 kg, although it is still very heavy, but for the previous 75 guns, 1300 kg of weight, it can definitely be a lot lighter, a strong soldier can carry it on his back and do short distances, and the total weight will not exceed 250 kg, which is definitely extremely light.

As for the 47 gun, it has also been initially improved, the weight does not exceed 400 kg, but unfortunately the 47 gun is a little bigger, Yang Yuanzhao's division is not very thorough, it can only be divided into 3 parts, the heaviest part, more than 200 attacks, Yang Yuanzhao still gave up the intention of dividing, left and right 400 attacks, with a horse to act, it is not difficult, after modifying the wheels, a horse can be easily pulled up, compared to the heavy 75 guns, it is already much stronger.

After setting up a continuous system of 100 30 guns and 47 guns, Yang Yuanzhao began to think about what would happen after leaving.

Lasted a month, Yang Yuanzhao's trip to Shanghai, it should be said that it was a complete success, if there is anything missing, that is, about the chemical machine qì equipment, this is also a helpless thing, the whole world, the era of chemical industry, still belongs to cutting-edge technology, at least for China, this is no market, China's chemical industry, I am afraid that it will be more than ten years later, there will be Hou's alkali method, breaking the breakthrough of China's chemical zero.

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

However, in addition to the omissions in the chemical industry, other basic industries are complete, in the eyes of Yang Yuanzhao's later generations, especially from the Shanghai sailors to obtain a large number of advanced steam engines, as long as part of the materials are replaced, they can be turned into small steam engines, can provide a strong and stable power for the factory, so that no matter what the factory, there will be extremely high efficiency.

Sleepless all night, constantly considering all kinds of omissions, under a thousand clues, Yang Yuanzhao was busy until the early morning, and then fell asleep in the daylight, another morning in Shanghai arrived, and the day of leaving Shanghai was getting closer and closer.
