As an example, the most powerful bed crossbow in history seems to be the three-bow bed crossbow hundreds of years later. In other words, three sets of bow arms are used to strengthen the power of the bed crossbow. Such a bed crossbow can even reach about 1,500 meters. Of course, this is just the range, and the effective range naturally cannot reach this distance.

However, the effective range of hundreds of meters has exceeded the advantage that can be dealt with in this era, and even this distance is farther than a catapult. In fact, the number of times used catapults in ancient China was not too many.

The number of times crossbows is used far exceeds this. However, Huo Gang has already thought about the next step of weapon development. It is very simple to develop black gunpowder. The Firearms Research Institute has already developed black gunpowder. Their main approach now is to constantly study brand new launch drugs. Huo Gang is not ready to develop a medley gun, so he is ready to come up directly and go for smokeless gunpowder.

Of course, Huo Gang didn't care whether it could be developed. The reason why he developed gunpowder was prepared for the industrialization of three acids and two alkalis, and he always had to give them a goal.

At present, they can complete it in a small amount, mainly because their understanding of these things is not as good as that of this era. After all, there is no chemistry knowledge in this era, so those who can enter this research institute are the top talents at present. They all study by themselves and then conduct self-verification research.

This research process is actually very dangerous, but the improvement of black gunpowder is also being carried out simultaneously.

These are all understanding of chemistry, so Huo Gang did not stop him. Anyway, he is not under much pressure now and is not in a hurry to directly develop the musket, so he can give them enough time to develop the R&D.

But no matter how slow this time is, when the children who are learning new basic education grow up, they will be educated completely according to modern methods. When they learn chemistry, there will always be some geniuses.

This time is not too long, at most three to five years.

Because there are not many things to learn in this world, especially mathematics, they are still very basic, so they have enough time to learn other knowledge, so the learning time is naturally much shorter than in later generations.

At this time, bed crossbows can be made now. As for maple trees, it doesn’t matter at that time. Large-scale afforestation will always have benefits and no harm. It is also good not to put them there to see the scenery at that time, so Huo Gang will not stop it.

"The bed crossbow can be made. With the pulley, the bed crossbow should be able to be pulled more easily, right?" Huo Gang said.

"Chief wants to go and have a look?"

"Let's go." Huo Gang nodded.

The two of them turned over and took a team of guards to head straight to the Weapons Research Institute. The Weapons Research Institute is a bit far from the Industrial City, but it is not too far from the Industrial City. On the west side of the Industrial City, a area was drawn near the foot of the Qilian Mountains as the place where the Weapons Research Institute was drawn.

Five hundred Tiger Army soldiers have been defended here, and almost all roads entering here have been blocked. The confidentiality here is higher than that of Industrial City.

After entering the Weapons Research Institute, it is divided into three areas. The area on the left is where you study crossbow arrows and other engineering equipment, such as some ideas Huo Gang actually gave them before, methods to quickly build bridges, etc.

Of course, these are just giving them a creative idea for them to think about it here, not afraid of them wasting money, because they can't waste much money, but they can let them use more ideas to see if it can be effective.

"Chief." is responsible for Rumu here. Because of the cultivation of many technical jobs such as fitters, woodworking is no longer needed in many places. Moreover, woodworking is actually the best to cultivate. The spinning machines have been produced before, and a large number of woodworking workers have been cultivated.

These carpenters dare not say that they are of Rumu and others, but there is no problem in helping to process some abrasive tools, so those little jobs can no longer be used.

"Show me your crossbow." Huo Gang nodded.

"Yes, please come with me, leader." Rumu nodded and took Huo Gang directly to the weapon test site.

This test site can be said to be a huge playground. After coming up, Huo Gang saw a huge bed crossbow placed there, which is actually not much different from the three-bow bed crossbow that Huo Gang saw on the Internet in later generations.

The only difference is that there are two moving pulleys on the three crossbow arms, and the bowstrings of the three bed crossbows pass through the middle crossbow path to save power. In fact, the pulley crossbows of later generations are combined into three links together.

In this case, the winch used by this huge crossbow is much easier than the crossbows of this era. According to historical records, the three-bow crossbows in the Song Dynasty are said to require 30 people to be able to be opened.

Considering the size of the bed crossbow, it is a bit unlikely to pull thirty people apart, but it is estimated that at least a dozen people are needed to use the winch, but this is not needed now. The winch uses a double-sided winch, and two soldiers on both sides can easily pull the winch.

This means that the skeleton crossbows are extremely fast. In conjunction with the soldiers who specially place giant arrows, their speed is several times faster than the current single-bow skeleton crossbows in the Tang Dynasty!

The power of such a bed crossbow on the battlefield can be said to be invincible. There are five crossbow paths in the middle of the bed crossbow. The one in the middle is a very huge giant crossbow arrow. Smaller crossbow arrows can be placed in the two grooves on both sides.

In this way, you can selectively use the different powers of the bed crossbow. In addition, the only difference between this bed crossbow and an ancient bed crossbow is that it has added a scope. To be precise, its approximate ballistics are calculated through scientific calculation methods, which means that its accuracy is much more abnormal than that of the bed crossbow of this era.

If two armies are facing each other, such a crossbow can directly fire 5 arrows. This thing really has nothing to stop its power. No big shield soldiers or heavy cavalry can do it.

"The leader is the bed crossbow we developed. According to our current improvements, its launch speed can be very fast. If well-trained, it can fire a wave of crossbow arrows at about 10 breaths." Rumu spoke seriously.

10 breaths is about 10 seconds, but if you launch this way, you need to use manpower to pull it away instead of a winch. This consumes a lot of physical strength for the soldiers, almost twice, which is also due to the moving pulley, otherwise, you can't even think about it.

If you use a winch, although the speed is a little slower, it can reach the point where you can completely open at 15 breaths.

If this were a Tang Dynasty crossbow, it would probably take at least one minute to launch it, and it would be impossible to launch it frequently.

"We used wooden and steel arrows to make crossbow arrows. If it was an ordinary brick-concrete city wall, we could shoot through a brick-concrete city wall about 500 meters thick at a distance of about 500 meters." Rumu introduced, signaling the soldiers next to him to start.

Huo Gang did not speak, but looked at the eight soldiers of the Tiger Army seriously. They showed the way of single crossbow arrows. A wall stood there four or five hundred meters away from here.

"Start!" As another soldier next to him waved the flag inside his hand, the four soldiers standing near the winch on both sides immediately began to rotate the winch at a crazy speed. As the winch rotated, the strings of the crossbow that were linked together in the middle were instantly pulled apart. With the sound of the sour creaking sound, the three giant bows of the crossbow bent quickly.

The person next to him was already waiting with a huge crossbow arrow.

When the bowstring of the "Ku" came in place, a soldier immediately shouted: "Be in place!"

The soldier holding the crossbow arrow quickly placed the special crossbow arrow as thick as his arm in his hand and directly into the crossbow path in the middle. After putting it down, he also shouted directly: "Set in place!"

Then the people below quickly began to operate the crossbow arrow and began to aim. A man on the left held a hammer and hit the trigger of the crossbow with a "bang". With a dull "boom", the crossbow arrow in the middle of the crossbow was instantly stretched away by huge force and pounced on the wall five hundred meters away.

With a "boom", with the huge roar and the dusty scene, a huge hole appeared directly on the brick wall standing in the distance. It was obvious that the crossbow arrows had shot through the brick wall directly.

"Let's go and take a look." Huo Gang was a little curious. To be honest, he had never seen these large-scale crossbow shooting scenes.

"yes!"

Following Rumu and the other two walked over. When they arrived in front of the wall, Huo Gang couldn't help but take a breath. The wall was made of fired red bricks and cement. A typical 37 wall, which is only 37 cm thick, was stacked side by side with standard bricks and stones, horizontally and vertically.

Although there is no steel bar added here, the strength of cement is much stronger than that of mud.

However, such a wall was shot out from the middle with a diameter of about 60 centimeters. If this wall was not big enough, it would have collapsed. The crossbow arrow flew at least a few dozen meters away after passing through this wall.

If calculated based on this distance, it is estimated that even someone behind the wall will be dead.

Thinking about it, Huo Gang felt that if this thing was shot directly on a person, it would probably be much more terrifying than the sniper rifle bullets in later generations.

"Chief, this is the reason why the wall is too thin. If it is a city wall, these crossbows can directly pierce into the city wall for dozens of centimeters. Our soldiers who siege the city can climb up directly with these crossbows." Rumu said.
