This new rear-loading rifle was named the "Da Ming Yi Style" rifle. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Due to the limitations of its production process and the difficulty of mass production of the new fixed-loading ammunition, Li Hongfei finally purchased only 1,000 and equipped them with the guard regiment directly under him.

Fortunately, a new type of fixed ammunition has been developed, and the revolver has been improved and upgraded again, removing the flintlock ignition device and adding a needle hammer, turning it into a semi-automatic pistol in the true sense.

Rifles and pistols are all individual equipment, and it is really difficult to form a strong combat effectiveness when it cannot be mass-produced, and the decisive factor in today's battles is artillery.

In the past, because of the fuse, most of the shells were solid, and they could only rely on strong kinetic energy to cause damage.

Flowering bombs are not absent, but they are time-consuming and difficult to mass-produce.

And the use of flowering bombs, must first ignite the delay lead on the bullet body, and then ignite and fire, its safety performance is not reliable, once the fuse is damp, or burn too fast, will cause the flowering bomb can not be detonated, or even detonated in advance.

The so-called blockade of a large area by the Furlong cannon is not to use flowering shells to blockade it, but to fill the barrel with a large amount of gravel, taking advantage of the numerical advantage and irregular movement, causing a wide range of strike effects.

When the Qing army attacked the city, it used the stones in the cannon chamber to continuously hit the city wall through the action of kinetic energy to achieve the effect of collapsing the city wall.

Even during the war, due to the lack of stones, many large-caliber heavy artillery directly used corpses as shells, stuffed into the chamber and fired.

This stone-loaded shell, with its limited range, inaccuracy, and severe wear and tear on the breech, greatly reduces the life of the gun, and if you want to continue to improve, in addition to using stronger steel, the improvement of the shell will become a top priority.

Now with thundermercury, the situation is different, as long as the needle ignition device is installed above the warhead, the new flowering bomb is completed.

The shell is not better than the bullet, the manufacturing process is relatively simple, and the emergence of the new flowering shell has greatly reduced the combustion residue in the barrel, and virtually accelerated the cleaning speed of the gun chamber, especially the rear-loading artillery, in the state of continuous fire, there is almost no need to clean the gun chamber, so that the rate of fire has naturally increased a lot, from the previous average of one round per minute, to the current two minutes three rounds, the rate of fire of the gun has increased by fifty.

The new type of artillery shell uses a conical warhead, which reduces air resistance and effectively increases the range, and in the past, solid shells were used, and they could only shoot about 1,000 meters of rear-loading Furlong machines, but now they can hit 1,300 meters away with flowering shells of the same weight.

Trigger shells not only have a wide killing range (according to the caliber of the gun, a radius of 10 meters to 50 meters), but also the surface of the shell itself is smooth and flat, which greatly reduces the wear and tear of the gun chamber, and the life of the barrel and the ability to sustain combat have been greatly improved.

As soon as the new flowering shell was developed, it was quickly applied to all rear-loading Furlong cannons.

As for the front-loading Hongyi cannon, because of safety issues (loading shells from the muzzle, which is similar to front-loading guns, it needs to be pierced into the bottom of the barrel with an iron rod, which is easy to directly trigger the thundermercury fuse, causing the shell to explode early), so you can only continue to use the previous solid bullet as the main type of ammunition.

In addition, Suzhou Heavy Industry has launched a new artillery construction program, intending to produce pull-hair guns.

The pull-hair artillery is the prototype of the artillery of later generations, and after the cannon is loaded, the bolt connected by the rope is pulled to activate the gun in the barrel.

This kind of artillery shell uses thundermercury as the primer, and uses impact to ignite, abandoning the disadvantages of arquebus ignition, and once successfully developed, it will greatly increase the rate of fire of the gun.

It's a pity that Chen Yujie, an expert in artillery manufacturing, was poached by Shi Kefa, and in a short period of time, it was difficult to study this kind of pull-hair artillery.

A series of new weapons began to be installed in the army units, and the sailors were also not idle, in addition to replacing the artillery with new shells, Li Hongfei invested a lot of manpower and material resources and began to study the steam engine.

Today's warships are propelled by wind and manpower, so it is impossible to get on the ironclad ship, because if the ironclad wants to defend against the enemy's artillery, the hull needs to be covered with a large amount of steel, and its weight can be imagined.

The only way to do this was to use a steam engine as a source of power.

The working principle of the steam engine is to convert steam energy into mechanical energy.

The world's first steam engine was invented by the ancient Greek mathematician, Heroof Alexandria (Heroof Alexandria) in the 1st century, which is the prototype of the steam engine.

The steam engine has a prototype, and now Suzhou Heavy Industry needs to overcome how to convert and utilize the energy in the steam.

In October 1644, not long after the establishment of Suzhou Heavy Industry, Li Hongfei asked Zhou Furen to invest a lot of money and began to study the steam engine..........

That's right, it took a year to make a pressure cooker, and its danger made many people dare not buy it at all, after all, no one wants to cook at home, the pressure cooker explodes, and the house collapses.

Therefore, the pressure cooker has become the only unpopular product in Suzhou.

Zhou Furen wanted to give up, but Li Hongfei insisted again and again, in order to please Li Hongfei, Zhou Furen had to continue to invest money in it, as if he was spending money to play with Li Hongfei.

After all, even Bi Maokang and Song Yingxing have nothing to do with the steam engine, and no one will think that they are more powerful than the two professors.

Of course, this is just that most people are making excuses for their own failures, and if others can't succeed, it doesn't mean that they can't succeed.

Song Yingxing's newly recruited apprentice, an apprentice named Li Zeshui, had such an abacus in his heart, wanting to become famous with the help of a steam engine.

Nowadays, Baoshan Town is vigorously developing the mining industry, in order to improve efficiency, Zhou Furen deliberately opened a department to develop special mining equipment, and it happened that Li Zeshui was assigned to this department.

Li Zeshui is developing equipment in the mining equipment research department, and he does not forget to study the steam engine at the same time, he himself is ambitious, but he is very pragmatic, and he knows how many catties and taels he has, so he never thought about it, and directly built a steam engine that can drive a warship.

And in order not to delay his work, Li Zeshui could only try to use the steam engine for mining equipment.
