Daqin Engineers

Shen Bing's transformation was actually aimed at Qin Jun's own situation.

First of all, the proportion of crossbows used by the Qin army is quite large. Although only 30% of the regular Qin army is composed of crossbow soldiers, the amount of crossbow equipment is as high as 80%.

Basically, except for infantry with long weapons, which is inconvenient to use bows and crossbows, all other arms have bows.

For example, a sword-and-shield player, when he is not charging or standing in the first row, he only needs to put his sword back in the shield, take out the bow and arrow from the quiver, and become an archer.

For example, cavalry and chariots, bows and arrows and crossbows are essential equipment.

In other words, this change of Shen Bing involved an upgrade of 80% of the troops.

Although this bow will have fewer upgrades, the arrow has also been changed to iron...

Previously, it was more difficult to make arrows with bronze...Bronze was brittle, hard and easy to break, and it was inconvenient to forge, especially when making the tip of the arrow cluster.

Iron is different after being transformed. Its unique toughness and sharpness are not only easy to make, but also much stronger in penetration and lethality than bronze arrows.

So Shen Bing immediately raised the troops' bows and crossbows, that is, their long-range equipment, to a new level.

The reason Oow knew this was because he had been trying to do it before.

In fact, it was not just him. During the Warring States period, many people tried to add a kick ring to the front end of the crossbow to make the crossbowman stand up and fight.

What is helpless is that the previous conditions are almost impossible to achieve:

Iron and bronze are brittle and easy to break. If you add a tread ring to the front end of the crossbow arm, and the crossbow does not move, it will be tens or even hundreds of kilograms of force, and the tread ring will break within a few strokes.

Therefore, it is not that Qin people did not expect to install the kick ring, but that there is no necessary condition.

This modification was not possible until Shen Bing made new iron.

There is no need for any testing and improvement on the arrow, just use the mold of the previous bronze arrow.

Because it is obvious that it was possible to use bronze arrows before, but now it is naturally feasible to replace them with stronger iron arrows, so mass production will not be risky.

Before the transformation of the crossbow went into mass production, Shen Bing kept a cautious attitude and tried to produce a few test pieces.

Then I found that there were some problems.

Qin Nu can be roughly divided into three types: 200 Qin Jin, 300 Qin Jin, and 350 Qin Jin.

There are three types of crossbows because each soldier's strength is different.

200 Qinjin is usually used by recruits with no combat experience.

The reason for using "normal" is that some powerful Qin soldiers who can drive 300 or even 350 Qin Jin will be deployed to another team.

It can be seen that 200 Qin Jin is the minimum requirement.

This requirement is not high. The modern weight unit of 200 jin is 101 jin. It is not difficult for ordinary adults to carry one hundred jin with their waist strength.

But if the weight is increased to 150 jin or even 177 jin, it will be a little difficult for a thin person.

In ancient times, people had poor food, especially when they were in their teens and had little training, so most of them were in teams that could only drive 200 kilograms.

But this is not absolute. After a few months of training in the army, the waist strength will become stronger and stronger, so it will be transferred to the elite crossbow that can drive 300 jin or even 350 jin...

These opening crossbow weights are not the maximum weight. We must know that we are in a state of tension during combat, and when we open the crossbow one after another, when the muscles are tired, it will be really weak.

In this regard, the situation of the Liang Army is much better than other armies.

The reason is that most of the Liangjun troops have training experience in the Wei Kingdom and they were selected by Shen Bing. After that, Shen Bing used modern fitness theories to practice.

Therefore, most of the crossbowmen of the Liang Army were concentrated in the crossbow teams of 300 Qin Jin and 350 Qin Jin, and only less than 500 people used 200 Qin Jin crossbows, and quite a few of them were recruits newly recruited in Chu.

The problem with the crossbow is that there is no problem with the crossbow of 200 Qin Jin using the pedal ring... the pedal ring can only be used with one foot.

But if the crossbows of 300 Qin Jin and 350 Qin Jin are used with circular pedals, it is difficult to open the crossbow... Originally, the crossbow was opened with two feet, but now with one foot, the strength will inevitably be lost.

So Shen Bing changed the circular pedal ring to a triangle.

That is, the bottom is wide and the top is narrow, and both feet can just reach into the loop to open the crossbow.

In addition, because in the past these crossbows were used to open the crossbow by stepping on the crossbow, now it is changed to step on the ring to open the crossbow, which will slightly extend the distance...

This has little effect on soldiers who are tall and powerful, but for soldiers who are insufficiently tall and have just passed the line, it will be difficult to open the crossbow as usual.

This problem is not difficult to solve. Simply lower the crossbowman by one level. For example, if you can't drive 350qin, you can adjust it to 300qin.

If you can't even open a 200-qin-jin crossbow, you can only go to the archer.

After making a few new crossbows for a few test shots, he couldn't help but praise:

"General, although this crossbow has the same range as the original crossbow, the rate of fire is much faster."

"More importantly, soldiers can stand against the enemy and are no longer passively controlled as they used to be."

"Especially when facing the Huns cavalry, I benefit a lot."

"The subordinates think this is very good. I can wait for the entire army to equip it and fight the Huns with its strength!"

What I owe is.

In the past, if a team of crossbowmen encountered an enemy cavalry, it was basically waiting to die.

Prepare for battle?

Preparing for war means having to sit on the ground and launch a crossbow.

Isn't that just waiting for the enemy to ride a war horse and step it into thin mud?

Especially the Xiongnu cavalry is still coming and going like wind, it is too lazy to use knives and guns.

Run away?

How can escape faster than the Huns cavalry?

Now with this kick ring, although it is still at a disadvantage against the Huns cavalry alone, at least it is not as helpless as before.

Crossbowmen can take a guerrilla approach to the enemy, disperse the formation, then maneuver to avoid the enemy cavalry, shoot the enemy cavalry with the crossbow when idle, and so on.

After seeing that there was no problem, Shen Bing ordered:

"Just make it like this."

"Be sure to complete all crossbows within one month."

"In addition, all the arrows have been changed to iron."

Benhe owed a response, and then ordered the blacksmiths to start work.

At this time, the iron smelting workshop has expanded to have 20 blast furnaces, and it is foreseeable that these blast furnaces are far from enough.

Because it is obvious that the crossbows and arrows should be used to stop the cavalry after the transformation.

In addition, it is time to develop the bed crossbow used to prevent the enemy from charging in batches... In the past, bronze was relatively brittle, and it was not practical to make a whole bronze arrow with it, and there was no such strong crossbow that could fire it.

But Shen Bingye's new iron, coupled with his knowledge and mechanical knowledge, made a powerful bed crossbow, isn't it a piece of cake?!
