Throne of Vientiane Civilization

Wang Dong always acted like a teacher. Except for Zhou Xu, he looked at everyone as students and children.

This is related to his professional habits, but it is also related to their age.

After all, under normal circumstances, in this primitive era, where people who lived to the age of thirty or above were considered to have a long life, they were indeed not very old.

"Okay, let's start the test."

Following Zhou Xu's order, the members of the patrol team who were recruited to serve as young men immediately began to operate around the three-bow crossbow under the command of Zhuang Mengdie.

"Break it here, yes, it's here, and it's the same on the other side."

Although the mechanism structure has been added to reduce the burden of operation, it cannot change the fact that the three-bow bed crossbow is still difficult to operate.

The people in their equipment department may not be able to keep up in terms of physical fitness and strength. For this reason, they called the guards from the patrol team to help them clear the area, and they also brought in six strong men.

Now it is Zhuang Mengdie who directs step by step, while the six guards do it step by step.

For Zhou Xu, this was just right, allowing him to gradually see clearly.

"There are two wooden prongs on both sides of the wheel at the bottom. Once put down, the wheel will be fixed and will not rotate."

While directing the guards to operate, as the manufacturer of this three-bow bed crossbow, Zhuang Mengdie certainly did not forget to introduce it to Zhou Xu.

"There are four fixed stakes at each of the four positions here. Yes, just pull them out and insert them into the ground."

Zhou Xu specifically told Zhuang Mengdie about the design of the fixed stakes. After all, if the recoil problem of a strong crossbow cannot be fully solved, the stability of the attack cannot be guaranteed. This is not suitable for operating a three-bow bed crossbow. It is also very dangerous for people.

But what Zhou Xu didn't expect was that Zhuang Mengdie's design of these four fixed piles was far more sophisticated than he imagined.

It seems that her genius mind came into play a lot when the research and development process was officially started.

"Then here, grab these two handles. After the fixed stakes have been driven in, you can move them left, right and up and down to facilitate aiming."

"The range of left and right rotation is still relatively large, but the space for up and down movement is very limited."

"Then there are these two big wheels on both sides. There are two people on each side. The four of you go over and grab the handles of the wheels and use force to turn the wheels at the same time."

Speaking of this, Zhuang Mengdie couldn't help but emphasize something.

"Remember, be as synchronized as possible."

Those who serve as patrol guards in the village have received a certain degree of military training, and they have a certain tacit understanding of working together.

Faced with Zhuang Mengdie's repeated emphasis, the four of them exchanged glances with each other, and soon the password "one two one two" sounded. In accordance with the password, the big wheels on both sides started to rotate smoothly and at a constant speed.

During this period, Zhuang Mengdie certainly did not forget to introduce and explain to Zhou Xu and the others.

"If one of the two wheels is fast and the other is slow, and the difference in progress is too large, it is likely to get stuck. At the same time, it cannot be turned too fast, otherwise there is a risk of dislocation and disconnection. It must be turned at a constant speed."

"However, even if the principle of the pulley block is used to reduce the strength requirements, these two large wheels are still very heavy. Under normal circumstances, if you want to turn too fast, you may not be able to do it."

After all, technology has not reached that point yet, and it is normal to have some limitations in its use, not to mention that these limitations are within the acceptable range for Zhou Xu.

After the four of them worked together to draw the bow, as Zhuang Mengdie waved, the other two guards on the side came over carrying a giant crossbow arrow matching the size.

The arrowheads are made of copper for the time being. After all, there is still little iron ore at the moment, and it is too late to use it to forge weapons for the soldiers. How can there be any excess for them to make these consumables?

As for the target used to test the weapon this time, it was the rocky mountain in the distance!

The rocky mountain was not big or small. At the beginning, Black Moon Village was still small, and the rocky mountain was not close to their camp.

But it couldn't be tolerated. In the following days, the scale of Black Moon Village continued to expand.

Especially when this village also shoulders the mission of farming and needs to cultivate a lot of fields.

Gradually, this rocky mountain began to become an obstacle, and its location obviously restricted the further expansion of Black Moon Village.

If the stone output from several mines was not enough for them, and the current labor shortage was still in short supply, he would have mobilized manpower to level this stone mountain.

And now, it just serves as a target for them.

"What's the distance now?"

"Three hundred meters."

"let's start."

After giving the order, there was only a sound of piercing the air, and the huge copper crossbow arrow flew out of the air, and with the flying gravel, it sank directly into the stone mountain!

This was an exciting blow that made the two modern men, Zhou Xu and Wang Dong, feel their hearts twitch.

Although modern people in the age of the information explosion have seen a lot of everything, but they have no chance of seeing the three-bowed crossbow launch an attack with their own eyes. The giant crossbow arrows were pointed in front of them and sank into the mountain with a 'dong' sound. Not really.

This kind of personal experience brings them sensory stimulation that is definitely not something that a video or a piece of text can bring.

After taking a long breath, Zhou Xu's smile reached the point where he couldn't hide it at all.

At this point, this three-bow bed crossbow already has the most basic lethality!

"Push the distance another hundred meters."

Although I didn't go to Shishan for confirmation, I could tell from a quick glance that the power of this crossbow was quite high.

There is no need to try it slowly bit by bit. It is more efficient to directly zoom out to a hundred meters.

During this process, it is inevitable to put away the stretched three-bow bed crossbow.

Since this was the first time for the guards to perform the operation, the whole process was inevitably a little hectic.

Zhou Xu had no idea about this.

After the test is completed and more three-bow bed crossbows are manufactured, this set of operating procedures will definitely need to be trained, and all operations will be completed in the shortest possible time.

There is no need to time it now.

After putting away the fixed stakes and untying the wooden forks on the wheels, the people from the equipment department quickly brought the cattle on the side over and hitched them in front.

This three-bow bed crossbow is not light in weight. In order to increase the strength and toughness of some structures, they have used copper parts after many tests.

In this case, it can be pushed by human power alone, but the movement efficiency is very poor.

So in order to ensure the efficiency of movement, they use oxen to pull them.

Later, if conditions permit, you can equip this three-bow bed crossbow with a horse, and then the movement efficiency will be even higher.

Measuring the distance with their steps, they quickly moved to a position of four hundred meters.

The second time they deployed the three-bow crossbow, the guards were undoubtedly more skillful in their movements.

After many tests, we finally came to the conclusion that at a distance of 450 meters, the arrow part of this three-bow crossbow can barely penetrate the mountain. If it is pulled further away, the giant crossbow arrow flying past will be blocked by the mountain. Bounced open.

In this way, it can be concluded that under the condition of ensuring the lethality, the current effective range of the three-bow bed crossbow should be in the range of 400 meters to 500 meters.
