With the first, it is not difficult to build the second.

Song Yingxing found some top craftsmen, these elders of the craftsman industry, the error of the things knocked out by hand will not exceed 0.01 mm, which can be called a humanoid machine.

It took them a few days to forge a batch of Migne rifles, and after the trial, several unqualified ones were eliminated, and finally about fifty qualified Migne rifles were left.

As for bullets, it's even simpler, Mingne bullets are cast from lead, and there is no such thing as lead that has a high melting point.

Therefore, Song Yingxing asked these craftsmen to create a batch of extremely high-precision molds, and then directly poured them, and after they were formed, they were polished by hand to complete the final process.

In this way, the production speed of the Minne bullet becomes very fast.

And Bi Maokang has not been idle these days, he transferred a few top craftsmen, and began to try to make the simplest wooden rifling machine.

Although there are no drawings in the later annotations, the principle and construction are clearly explained, and with the ability of these craftsmen, it will not be long before they can be reversed, and by that time, the forging speed of the Mineer rifle will be greatly increased.

In addition, Bi Maokang also thought that he could go further and get the breech gun mentioned in the annotation.

After all, although the Migne rifle has a long range and high accuracy, it is still a breech gun after all, and since it is a breech gun, it cannot avoid the disadvantage of a breech gun, that is, the slow rate of fire.

Breech guns are loaded by pouring gunpowder into the muzzle, then stabbing a long metal rod into the barrel to compact the gunpowder, and then placing the bullet into the barrel.

This method of reloading is extremely cumbersome, and it takes more than twenty seconds for even a well-trained soldier to reload a round, and if it is on the battlefield, it will only be slower.

So Bi Maokang was desperate to get a breech-loading rifle that could be loaded from behind, and according to the annotations of later generations, even the most rudimentary breech-loading gun could fire five or six rounds per minute.

This is compared to two or three rounds per minute of the breech gun, although the rate of fire is only doubled, but for the entire army, it is a qualitative leap!

It's just that the breech gun has a huge difficulty, that is, it needs thunder mercury, and thunder mercury needs things, and it is a bit difficult to make it with the productivity of the Ming Dynasty, so Bi Maokang and Song Yingxing will first engage in the Migne rifle, and have no idea of hitting the breech gun.

After all, the meal has to be eaten bite by bite, and things have to be done step by step.

And now, after getting the Migne rifle out, when it can be mass-produced, they have put the development of breech guns on the agenda.

Song Yingxing's fifty Migne rifles that they urgently created did not stay in the capital, Wang Guoxing selected a group of top firecrackers from Jinyiwei, and after they were familiar with the Mineer rifles and could ensure accuracy, they directly asked these Jinyiwei to take these fifty Migne rifles and 2,000 rounds of ammunition and rushed directly to Huangyaguan secretly.

……

In early November, Huangya Pass.

Lao Zhu and Abatai have been in a stalemate for more than a month, and during this time, the two sides have been back and forth, casualty and casualties.

It's just that because Lao Zhu is the defender of the city and occupies the initiative, according to the casualties, it must be that the Abatai side has lost more people.

The more than 70,000 people in Abatai have now lost more than 10,000 people, even if these people are cannon fodder, they can't be consumed like this.

The most important thing is that the guards in the Yellow Cliff Pass seem to be able to see his hypocrisy, as long as he sends people to attack the city, the defenders in the city do not use cannons, but only use bows and arrows and some defensive equipment to kill the enemy.

And once he got to the elite, the opposite side immediately opened fire, which made Abatai very uncomfortable.

So now Abatai has become quite conservative, and basically doesn't attack the city much, even if he sends people to attack the city, most of them are sheep attacks.

Those people also knew what Abatai meant, so they just went through the motions, basically carrying shields, and before they could rush to the edge of the city wall, they had already retreated like a tide.

As a result, although the casualties on Abatai's side were much less, the pressure on the city was greatly reduced.

It's just that this season, there is less rain, so the heavy rain that Abatai had been expecting did not happen.

During the period, there were a few light rains, and Abatai also took the opportunity to attack a few times, but the impact of the light rain on firearms was not very great, so those few sieges, instead of taking down the Yellow Cliff Pass, made his command lose a lot.

In this way, Abatai completely extinguished the plan to attack the city and patiently waited for the arrival of the heavy rain.

Abatai's patience is good, he has plenty of food and grass anyway, even if he waits a few more months, he can afford to wait.

It's just that he has such a steady style of play, and Lao Zhu Ke is not satisfied.

After all, we still expect you to train our troops, what's the matter with you pretending to attack the city? The army withdrew before it reached the city wall, so how can we train this soldier?

Book of Hundred Leagues

Therefore, Lao Zhu Yi didn't just defend the city, and often asked Tang Tong and them to take turns to take the new soldiers out of the city to take the initiative to attack the Abatai camp.

After all, Tang Tong, as the chief soldier, was not much worse than Abatai in terms of his ability to command operations, and he knew very well when to retreat, so it was difficult for Abatai to keep him.

And if Abatai directly mobilizes a large army to encircle and suppress Tang Tong, then the artillery on the city wall will cover Tang Tong's withdrawal, and Abatai has no temper at all.

In this way, although the casualties on the Ming army's side were much greater than when defending the city, these soldiers who had experienced blood and fire could quickly transform into veterans, and their combat power was greatly enhanced.

The current Ming soldiers are not short of salary, there is no shortage of equipment, according to Lao Zhu's method of training, even if he goes back to fight head-on with Jiannu's Eight Banners, there will be no problem.

……

Just when the two sides were at a stalemate, Lu Wenzhao, a hundred Jinyi guards, secretly rushed to Huangya Pass with five hundred Jinyi guards.

Lao Zhu looked at the secret letter written by Song Yingxing, and then looked at the fifty Migne rifles that Lu Wenzhao brought, and his heart was suddenly full of surprise.

But because there were many people at this time, Lao Zhu didn't show it, but just settled Lu Wenzhao and them first, and also forbade others to disturb Lu Wenzhao and them.

After the affairs in the city were dealt with, Lao Zhu, who had long been unable to sit still, directly asked Lu Wenzhao to take people to a relatively secret shooting range, and he also set up heavy troops on the periphery of the shooting range to prevent others from peeping.

"This thing, this can hit 900 meters?"

Lao Zhu picked up a Mine rifle and looked at its exquisite workmanship like a work of art, and couldn't help but feel a little excited.

When he was in the capital before, Song Yingxing and Bi Maokang had mentioned this thing to him, but Lao Zhu didn't care, but he didn't expect Song Yingxing and Bi Maokang to really sort out this thing.

You must know that in addition to artillery, the maximum range of bows and arrows and firearms is currently 200 meters, and the range at which they can cause effective damage is only 100 meters.

But now this musket has a range of an astonishing 900 meters, and an effective range of 500 meters.

If there are enough of them, wouldn't they be able to push the enemy army flat, and what other troops would they need?
