With the completion of the system upgrade, Jiangchuan has found that the production efficiency of the system has been doubled.

In just two days, all his orders for muskets and artillery had been produced, except for the warships.

Of course, these produced muskets and artillery are still within the base domain, and if Jiang Chuan wants to bring them to the real world, he must use the two-way exchange function of the system, that is, he must pay a fee to the system.

Although he complained that the system was a vampire, Jiang Chuan had no time to care about these things at this time, and he couldn't wait to exchange samples of new muskets and cannons from the system first, and planned to test them first to test the power.

When the new-style musket was in his hand, Jiang Chuan looked left and right, and felt that the musket in front of him was much better than he expected.

First of all, the revolving pull-back rifle used by the infantry.

The overall length of this gun even surpassed that of a breech-loading rifled gun captured from the Waiko, and the rifle produced by the system was significantly better than that of the rifle captured from the Waiko.

For example, a bayonet was added to the barrel of the gun, although Egawa still gave all musketeers a short knife for hand-to-hand combat. However, if you are on the battlefield, there may not be time for you to pull out your secondary weapons and fight.

Therefore, it is very necessary to equip the rifle with a bayonet, although this will affect the accuracy of the rifle to a certain extent. However, the lesser of two evils, adding a bayonet can make the soldier have a higher survival rate on the battlefield.

Another change was the addition of a dust cap to the reloading port behind the chamber.

In addition, the shape of the butt is more suitable for ergonomics and makes it more comfortable to hold.

Of course, Jiang Chuan thinks that the most critical improvement is the rotating rear-pull bolt that appears at the back of this rifle, which is the kind of revolving gun-pull rifle like an old sleeve that we often see in film and television dramas before.

Although in the era of World War II, that kind of old sleeve was already a very backward old antique, and was despised and disliked. But in this era, it is tantamount to a revolutionary part in the history of muskets

You must know that although the breech-loading rifled guns seized from the Japanese were reloaded from the rear, they still needed to be stabbed into the chamber with an iron strip before they could be fired normally.

In this way, the speed of shooting will naturally be greatly affected.

With the addition of the bolt, you can quickly push the bullet into the chamber by simply pulling the bolt, ready to fire. The rate of fire naturally increased exponentially.

Of course, one of the most fundamental improvements to the rifle is the upgrade from the original unrifled smoothbore gun to a rifled gun. Moreover, compared to the rifled gun in the hands of the Japanese Kou, there was only one rifling, and the musket in the system had two rifling.

What this represents, naturally, represents a longer range, a more stable trajectory, and a higher degree of accuracy.

This is from the point of view of the gun itself.

In terms of bullets, it turns out that the musket bullets captured from the Japanese were still paper shells.

If you put it before today, the paper shell bullet can be regarded as the most advanced musket bullet that Jiang Chuan has seen in this era.

However, compared to the upgraded musket bullets, this paper shell bullet can already be thrown into the garbage, because the bullets made by the system are now close to the streamlined pointed bullets of later generations, but the head is more rounded.

However, compared with the original paper shell bullet and lead bullet, the stability and penetration of the actual trajectory are much enhanced.

And after Jiang Chuan conducted the test firing, he finally found a little bit of the feeling of military training shooting from this rotary bolt rifle.

After Jiang Chuan test-fired, he was surprised to find that the effective range of this musket could reach 300 paces or even farther.

At a distance of three hundred paces, even iron armor can be penetrated.

And he found that after the technical upgrade, there was basically no white smoke after the original musket was fired, and there was basically no smoke.

This surprised Jiang Chuan, and thought that the system seemed to have upgraded the original yellow powder to black powder.

Compared with yellow powder, black powder burns more fully and is naturally more powerful.

In this way, it also clears the eyes of the soldiers on the battlefield, and it will not be filled with smoke every time they fight, just like demons dispatching.

The construction of the carbine is actually the same as that of the rifle, except that there is no bayonet on it, the barrel is shorter, and the stock has been improved to make it more suitable for shooting on horses.

As for the pistol, it was the same, except that the pistol at this time, compared with the pistols of later generations, had a longer barrel and a larger caliber. Moreover, the shooting distance is relatively limited, and there will be strong lethality within twenty steps.

But twenty paces away, the accuracy is terrible, and only God knows where the bullet will hit in the end.

Although you can only reload one bullet at a time, if you are proficient, you can fire very quickly.

As for the artillery, after upgrading from the original field gun to the howitzer, it has also undergone an all-round technical upgrade.

Including a longer barrel, a smaller caliber, and the barrel has changed from the original smoothbore to a rifle, that is to say, the rifling has been increased, which will make the gun fire at a longer range and with higher accuracy, and from the original front-loading ignition firing to the rear-loading cable-firing fire, the firing speed has increased several times.

And the shells have also changed from the original round shells to streamlined copper shells.

Moreover, auxiliary equipment such as gyroscopes for auxiliary aiming appeared on the gun body, so that the accuracy of aiming far exceeded the accuracy of the previous artillery manual aiming, and the firing speed was further improved.

The direct-fire gun is similar to the anti-tank guns of later generations, but it looks rougher, and the barrel is thicker and thicker.

The appearance of the two mortars is similar to that of later mortars, except that they look more bulky. Depending on the caliber, it is divided into light and medium.

Jiang Chuan ordered people to take these guns to the school ground of the military camp outside the city for test firing, and found that these kinds of guns were designed to meet the needs of combat at different distances.

Howitzers are better suited for long-range fire cover, while direct-fire guns are a loyal offensive and defensive weapon, and are useful against enemy siege weapons as well as infantry.

The two types of mortars are mainly for the infantry to carry more conveniently, and to provide limited fire support in a small area with the infantry as they advance.

The power of these muskets and cannons made Egawa very satisfied.

He quickly exchanged all the muskets and artillery he had made, and then left a small part for the guard battalion, most of which were escorted to the Weihaiwei front line and handed over to Hu Zongxian.

The new warships of the additional naval division have also been launched one after another.

After the construction is completed, except for the few fortified mountain harbors, the rest will be transferred to Deng Shichang in Weihaiwei.

Jiang Chuan believed that with this batch of advanced muskets and artillery, as well as the addition of heavy warships, the Qin army's water combat power could almost be said to be quite strong, and it could almost be said that it was possible to capture a group of thousands of Japanese pirates.
