After arranging these things, He Huan began to prepare for the most important things.

That is the development of military weapons.

It's not that He Hui doesn't want to develop thermal weapons now, but that he can't get gunpowder at all.

There is no gunpowder in this world at all, and He Huan has the ratio of gunpowder in his brain.

However, there is not even sulfur and saltpeter in this world.

I don't know if it doesn't exist at all, or if it hasn't been discovered for the time being.

In the previous life, in ancient China, these two things were used for medicinal purposes, and those Taoist priests in ancient times would also use these things in alchemy.

Gunpowder can be described as a must-have artifact for any traveler, especially in such an era of cold weapons.

Mastering gunpowder is equivalent to mastering the lifeblood of the world.

As long as you don't die, it is not a problem to unify the different worlds of the Cold Weapon Era.

Gunpowder is made by mixing charcoal, sulfur and saltpeter, but He Hui now has charcoal, but there are no other two things.

After asking Wang Xiu, he didn't know what saltpeter and sulfur were, which meant that there were no two things in this world.

They are all minerals that can be mined as soon as they are found, but they are not.

This made He Hui very helpless, and it was impossible to make gunpowder for the time being.

I can't think about hot weapons now, but I can make other weapons, and this is also an era of cold weapons anyway.

In that battle, what annoyed He Huan the most was that there were no long-range weapons, and what he was going to make now was long-range weapons.

Perhaps this is also He Huan's personal hobby, even in his previous life, he liked to play games and choose characters remotely.

When he came to this world, he also wanted to make long-range weapons first.

Ranged weapons, get rid of bows, crossbows are a good choice.

This world is too strong due to the personal force value, even if it is still in the era of cold weapons, but some weapons that were possessed in ancient times in previous lives, this world does not yet exist.

They prefer to charge and kill, and there are no other ranged weapons besides the bow and arrow.

However, this also gives He Harmony a lot of room for development.

There are bows and arrows, but crossbows are not.

Crossbows have a longer range and more penetration than bows.

And it can also launch with a delay and will also have a higher hit rate.

When fighting in large armies, you can craft larger crossbows and reload them with arrows in advance.

The power of the crossbow is extremely great, and the firing distance can reach several times that of the bow, but the speed of loading arrows is not as fast as pulling the bow directly on the arrow.

However, since the launch can be delayed, the first wave of arrows can be fired faster than the opposite side.

And because of the huge power and the long distance, it is estimated that the first wave of crossbow arrows will be launched, and the opposite side will die.

In general, the crossbow is characterized by its long range, as it requires more force than a bow when opened.

Second, it can aim at the target and has a high hit rate.

To put it bluntly, the crossbow is an enhanced version of the bow and arrow, which can be aimed at the target and wait until it is needed before firing, which is conducive to capturing the timing of the shot, and the hit rate is higher than that of the bow.

Third, it can fire several or even dozens of arrows at the same time, and the combat power is strong.

So, a crossbow is more practical than a bow.

Of course, this will have to wait until He Harmony develops a repeating crossbow.

The power of the crossbow was well reflected in the ancient times of the previous life, and there was the Qin crossbow that shook the Quartet in the early days.

Later, there were also the big yellow crossbow of the Han Dynasty and the divine arm crossbow of the Song Dynasty.

The body length of the divine arm crossbow is three feet three, the string length is two feet five, and the range is more than 340 steps, that is, more than 370 meters.

And it shoots out such a long distance, and it can also enter the elm half-rod, which shows its power.

At that time, it was said that other instruments could not catch up, and it became one of the standard weapons of the crossbowmen of the Song army at that time.

Even when the Jin army attacked later, its general Wanyan Zongbi also praised the divine arm crossbow.

said that the Song Junshen arm crossbow was the most powerful, followed by the heavy axe, and he didn't pay attention to the rest.

Even the enemy commented on it, which shows how powerful the Divine Arm Crossbow is.

Considering the speed of reloading the crossbow arrows, He Huan was ready to arrange it like a musket team.

Prepare the arrows in advance, and then divide them into several rows, the first row shoots, the second row shoots, and the second row shoots the third row.

In this way, the first row can continue to reload after shooting, and during this time, the second row will continue to fire and suppress.

The task of crafting a crossbow can be given to those craftsmen who make bows.

The drawings are drawn by He Harmony, and then the materials are selected by those craftsmen, as long as they can achieve the power that He Harmony envisioned.

As long as the crossbow is made, it can be improved again, and when the time comes, it is not impossible to make a repeating crossbow, and the ballista is not impossible.

The ancient ballista in the previous life was also known for its powerful power, and the repeater of the Warring States period was said to be able to shoot 700 steps, and the wall in the middle was destroyed, and the power was unstoppable.

The walls can be shot down, and this is a cannon!

What impressed He Harmony the most was a kind of crossbow in the Song Dynasty, called the bean + inch crossbow.

This is a powerful repeater, a type of three-bow bed crossbow in the Song Dynasty. It can fire more than ten arrows at a time, shooting up to a thousand paces.

Such a distance can already be said to be the longest-range cold weapon, right?

It is also said that it takes more than 75 to 100 people to twist the string with ropes, borrowing the power of machinery, and it is a very powerful weapon.

If this is not blown, it is not a fictitious existence.

Then I have to admit that the bean + inch crossbow is more powerful than the ballista during the Warring States period, and it is a well-deserved rocket artillery in cold weapons.

Shooting over the city walls is not a problem at all, and it is definitely a weapon among the sharp weapons to siege the city.

It's just that He Hao only knows about these crossbows, but he doesn't know how to make them.

Considering that weapons would definitely need to be used on a large scale in the future, He Hui ordered an arsenal to be built in the city and installed doors to make weapons.

Whether it is a sword, a sword, a halberd, a crossbow or an arrow, it is produced here.

Most of the iron that was trained was also used in the arsenal.

…………

After He Harmony's heavy checks, it took more than half a month for craftsmen to work day and night to develop and develop, and the first crossbow was finally manufactured.

This crossbow was made by He Harmony by imitating the length of the Divine Arm Crossbow and the length of the string.

That is, a three-foot-three crossbow body, with a two-foot-five string length.

The bow body of this world is made of a single wood, and composite materials have not yet been developed.

In the previous life, composite materials for making bows and crossbows already existed in the Warring States period.

Isn't it that the level of this world is not as good as the Warring States period?

Could it be the Shang and Zhou periods?

Without thinking about what period the world's scientific and technological level was in the previous life, He Harmony let the craftsmen make the first batch of composite materials through his vague memory.

The crossbow body is a composite material made of using topwood as the main raw material, and then stacking bamboo, and other wood materials, under multiple bonding, to increase the strength and toughness of the bow body.

The main source of the power of the arrow is the strength of the bow, and the stronger the bow, the greater the power of the arrow.

Composites are much more powerful than wood alone!

As for the strings, the requirements are not very high, the main thing is that the resilience should be high, and it must be strong and durable.

As long as these two conditions are met, even if it is rubbed out with hemp rope, there is no problem.

The bowstrings of this world are mainly made of processed animal tendons, such as deer tendons, cow tendons, and so on.

There are also plant fibers, or silk rubbing, or directly with hemp rope.

He Hui chose plants.

Although the tendons are treated, they are still afraid of water, especially in the south of Yuezhou, where the climate is humid.

Using tendons as crossbow strings is really not a good choice.

He chose brown for the plant, and he was familiar with these two things, that is, the raw materials for the production of the cloth.

After drying, it can be used to weave a coat, which is rainproof and waterproof, and can also keep warm.

In other words, it is not afraid of rain, and it is strong and durable, and the source is easy.

It doesn't matter if you use a bad string a day, anyway, there are so many that you are not afraid of consumption at all.

However, just in case, there are still spare silk strings, and as for the tendon strings, they are no longer in the scope of He Harmony's consideration.

As for the power, it is definitely not as powerful as the Divine Arm Crossbow, but it will definitely be stronger than the bow, after all, it is a composite crossbow body.

No matter how bad it is, it is not comparable to a bow.
