Although the convex gun has various shortcomings of hurting oneself first and then others, in the era of low human rights, this shortcoming of the convex gun is not considered a major disadvantage of hurting one's muscles.

The rulers are difficult to feed their soldiers even if they are not paid out, and the military pay may not be paid out. If a person dies, he is like an ant, and he can swallow up more than half of the so-called pensions. Will they care about the shortcomings of the fact that the constrains will cause soldiers to be injured?

Such a cheap and powerful military force can produce economic victory even if it is piled up with human lives.

Therefore, this disadvantage is a huge driving force for countries to develop musket technology faster, allowing them to change their troops more quickly, gradually eliminate expensive weapons with high training costs, and cheap weapons with low training costs.

In this process, firearms gradually became the mainstream of the world's army.

Of course, Su Yonglin is also the ruler, and the low training cost of firearms is also a huge temptation for Su Yonglin.

Before the musket was born, the divine arm bow was really expensive! The powerful crossbow was really expensive!

Although it has mature technology, the labor time it takes to build them is really long, and compared with the production cost of muskets, the Divine Arm Bow and the Strong Crossbow really have no advantages.

And it's very troublesome to train! It's very expensive!

With the same money, why not train a musketeer who is several times more than a crossbowman?

What's more, this is the mainstream development direction of future wars. If there is no better choice, how can we stop moving forward?

Su Yonglin then decided to train these two hundred people to death.

When more muskets were made, more high-quality soldiers from the Ming Dynasty were brought to start training, preparing to build them into the first musket team, and was also the earliest musket team reserve officer in the Ming Dynasty army.

After the number of muskets increases in the future, they will immediately serve as the backbone of the army, pull out a large-scale musket force, officially enter battlefield operations, and kick off the prelude to the war in the musket era.

Having said that, some difficult problems still exist.

For example, the barrel size problem caused by hand-made muskets.

In the era without machine manufacturing, two guns made by the same craftsman will have different barrel sizes, so the fixed ammunition will face threats.

What should I do if I can't fit in the size?

Strongly stuffed in?

Then wait for the explosion.

When training musketeers, Su Yonglin encountered this problem.

Some gun barrels were really unable to be stuffed into the iron bullets, even if they were lubricated with oil, some despicable soldiers still silly and refused to report them. As a result, the gun was ruined and several people were injured.

fracture.

So after comprehensive consideration, Su Yonglin decided to abandon the iron bullets and change the projectiles fired by the musket into lead bullets that are easier to polish and have a softer texture. At the same time, the musketeers were equipped with grinding tools so that they could master the technology of grinding lead bullets to make them more suitable for the barrel caliber.

The Firearms Bureau provides projectiles and ensures that the barrel size is convergent as much as possible. However, when it cannot be done, the musketeer has to use his own tools to polish the projectiles that suit his gun.

After a period of time, the musketeers mastered the skill of polishing lead bullets. They would polish the lead bullets almost to the size of the barrel, then wrap them with a thin layer of linen, apply some oil, and then they can smoothly stuff them into the barrel.

Although most of the lead bullets they polished are not very regular in their package, such ammunition does have advantages.

During the experiment, Su Yonglin found that a lead bullet would bring great lethality to the target when it hits the target.

For example, a wooden box can be broken directly.

While using pigs to perform mobile shooting experiments, ten musketeers shot together, and only one of them hit the running pig.

But this lead bullet hit directly exploded the belly of a pig that had been hundreds of pounds, and blood flowed all over the ground, and internal organs flowed all over the ground. The pig died on the spot.

Su Yonglin feels that many modern guns do not have such lethality.

Su Yonglin didn't quite understand the principle, but he thought that this irregular hand-grinding ammunition, perhaps because of its irregularity, would cause such terrifying lethality to the creatures, that once it hit, it would basically be a explosive blow.

The probability of death is very high.

Although the shooting accuracy and range are far inferior to modern guns, as long as this kind of firepower is concentrated and the amount is large enough, the damage it brings to the enemy will be very terrifying.

Therefore, even if the mesh gun has so many significant and difficult-to-solve shortcomings, low training costs and high mortality rates are enough to make the ruling class unable to give up, and continue to strive for excellence to develop such individual muskets.

Su Yonglin was of course not immune to the vulgarity. He constantly drew high-quality soldiers from Ming Dynasty to turn from crossbowmen to musketeers, equipped them with musketeers, allowing them to practice musketeers every day, and even equipped them with spearmen and swords and shields who could match combat to train combat formations.

By the middle of the four years of Hongwu, he had formed a 2,000-man musketeer unit.

On the other hand, in mid-March of the fourth year of Hongwu, with the advance technical accumulation, the light cannon of the mother-child gun requested by Su Yonglin was born.

The same iron core copper body, about 1.7 meters long, and weighs 3.500 kilograms, can achieve its own maneuver through the wooden wheelbarrow that it matches. It can achieve faster maneuver through a pack horse, a donkey, a mule, and a manpower.

Moreover, the number of soldiers that this type of light artillery needs to be operated is far less than that of heavy artillery. It is relatively easy and can be put into the battlefield on a larger scale.

Su Yonglin watched the strategic test launch conducted by the craftsmen and artillerymen.

They arranged a large group of about 600 scarecrows neatly, put on the stance of military formations, and then listed five light artillery pieces and fired at a distance of about 200 meters.

After a roar, all five iron bombs were shot into the Scarecrow Army, causing different damage to the Scarecrow Army.

But this military formation was basically destroyed, there is no doubt about it.

Looking at the messy scarecrow army formation, Su Yonglin thought that if it were the flesh and blood Song army formation, the scene would have been very bloody.

In about a month later, Su Yonglin obtained some very accurate data.

For example, the maximum effective range of the current model of heavy artillery, that is, the direct firing distance of the elevation angle does not exceed five degrees, is about 700 meters.

Within this distance, heavy artillery can cause effective direct strikes on the target.

If the elevation angle is raised so that its range exceeds this distance, the shell can still fly, but wherever it goes depends on its own ideas.

It is free.

This is the transmission data after improving gunpowder and emission technology.

The initial data did not reach this level, so Su Yonglin suggested that the iron bullets be bound to a wooden base, and use their experience in firing Thunder Cannons to make the iron bullets and wooden bases form a badminton-style top-heavy and light-footed self-stabilizing structure to enhance stability and thus increase the range.

The craftsmen improved the ammunition structure based on this, thus improving the effective range of the heavy artillery and improving the accuracy.

The launch effect of the heavy artillery after the granular gunpowder and self-stabilizing structure reached a point that Su Yonglin was more satisfied.

The light artillery also supported the above technology and achieved an effective range of 250 meters to 300 meters, which made Su Yonglin more satisfied.

If you want to continue to increase the effective range and shooting accuracy in the future, you not only need technical support, but also use gazes, sights, etc., and also calculate ballistics, and you need to allow artillery soldiers to master certain professional knowledge and develop in a more professional direction.

This newly established firearms unit does not yet have such strong professional strength. Many things need to be explored continuously.

During this period, what Su Yonglin could do was provide them with sufficient funds and sufficient training grounds and materials so that they could become more proficient.

At the same time, he also asked high-quality officials from the Imperial College in the Firearms Bureau to come to count the data, provide mathematical support to the officers and soldiers, and impart their basic mathematical knowledge.

After such accumulation, artillery can only play a decisive role after really getting on the battlefield.

But no matter what, the times have changed.

Gunpowder and steel are changing the Ming army.

Su Yonglin quickly advanced the military revolution of the Ming army in Zhongdu, making the Ming army stronger and more professional. At the same time, the Southern Song Dynasty did not make any progress and even retreated.
