"Ah, brother, you will, great!"

After all, Xia Qi was a child, and he didn't think much about Xia Yu's strength, so he suddenly jumped up from the ground and hugged Xia Yu: "Brother, you must teach me, if you win him, that Tianluo Yi will let you take it, I just need to watch him lose and cry his nose, haha!"

"I'm not sure, but want to give it a try. ”

If you only look at the rate of fire, or if you don't consider the overall lethality, Xia Yu really has something in his heart that can be compared with a repeating crossbow.

Gun.

In Xia Yu's view, although the use of machinery in this world is already very clever, the source energy mechanism civilization has only appeared for more than 1,500 years, which is too short, and perhaps because there are so many super powerful organs and super strong mechanism monks above 3 stars, as a 2-star civilian weapon, its development has not reached the level of the earth after the 20th century.

As far as he knew, the Source Energy Crossbow Arrow was indeed the main weapon of the ordinary army with 2-star strength.

In addition to ordinary hand crossbows, this world already has strong crossbows, cross crossbows, repeating crossbows, multi-horned crossbows that can fire in a salvo, and even super-large bed crossbows, etc., it can be said that in addition to using sources to make the power faster and stronger, as one of the most popular attack mechanisms in the world's 2-star stage, the development of crossbows has been quite mature.

But Xia Yu still feels that the shooting efficiency of the crossbow should not be as good as the most thermal weapon on the earth - the gun.

At the very least, crossbow bursts are cumbersome, because it takes a lot of time to reload arrows, and bursts are too simple for a gun.

He wanted to give it a try.

————

Because he promised his sister that the new mechanism would be delivered within three days, Xia Yu did not hesitate any longer, he first studied the source shooting crossbow of Xia Hadron.

Although the source box of the crossbow was slightly damaged, the tongue of the crossbow was also seriously worn, and even the 2-star source crystal inside was exhausted, and it could no longer be triggered normally, but it could still be used as a reference, so Xia Yu borrowed it from Qiangzi - under the guarantee of "pay you back absolutely intact".

Immersed in the hut alone, Xia Yu concentrated, as if he had returned to the laboratory of the earth.

He used delicate tools to disassemble the crossbow bit by bit, carefully analyzing the function of each part and the overall mechanical structure, which confirmed his suspicions.

"Sure enough!"

As he thought, the crossbow in this world is actually very similar to the prototype of the gun because of the effect of source energy.

On Earth, the common principle of crossbow is to shoot arrows at high speed by the kinetic energy formed by the rapid rebound of the open bowstring.

It's very simple to fire, just like a musket – just pull the trigger. But winding is much more troublesome, requiring you to place the tip of the crossbow on the ground, step on it with your foot, and then pull the bowstring back with both hands or with the aid of the crank, and hang it on the hook of the crossbow receiver.

However, the source crossbow in this world is much simpler to use, it does not use the energy of the bowstring elastic force at all, but also uses the source box to convert the source energy of the source crystal into kinetic energy.

Taken apart, in addition to the core source box, the external mechanism of this source crossbow includes: a wooden or iron crossbow arm, a bow hole to hold the bow, a grooved arrow channel for placing arrow clusters, and a sight called "Wangshan".

In addition, one of its most important components is the "crossbow tongue" - a special material shrapnel shaped like a tongue in a flat arc that absorbs the source energy emitted from the source box and then turns it into a violent elastic force that urges the arrow to shoot.

Of course, there are energy weapons in this world, such as the energy shield of "Yaori", which is actually a special structured source energy release, but it is all a realm of more than 3 stars. And the source energy below 2 stars, even if it is excited, does not have a qualified 2-star energy structure to carry it, and it cannot directly hurt people.

Therefore, this transformative crossbow tongue is very crucial.

With the Source Box as the energy source and conduction core, plus the crossbow tongue, the Source Crossbow naturally does not need to be strenuous to wind, only needs to be filled with arrows - this is much more convenient than the crossbow on Earth, and it is almost no different from the early muskets.

"Sure enough, it's a trap world, and this source-shot crossbow can already be regarded as a source energy gun in essence......"

Xia Yu sighed with emotion.

It is no wonder that this world has not continued to develop metal firearms, on the one hand, because the main focus of a large number of mechanics is not on 2-star "civilian weapons", and on the other hand, because of the source crystal and source box, the convenience and power of this source crossbow are no weaker than the early muskets of the earth.

Coupled with the huge profits of the monopoly group exporting source-fired crossbows, they are naturally reluctant to change course.

But Xia Yu wanted to try it himself.

Because, the repeating crossbow is not easy to make, and the body of the repeating gun is ...... It's too simple for a Ph.D. in mechanics.

Besides, he didn't even need to make gunpowder - although the recipe for making gunpowder was pretty simple - with the source crystal and source case, and the "crossbow" shrapnel, all he had to do was take advantage of the mechanics of modern firearms and turn arrows into bullets.

Thinking about the principle and method, what he lacked now was the materials, and he didn't think much about it, so he went to Uncle Chen.

——————

"What? Are you really going to make a new repeater?"

Inside the house, Lao Chen was drinking tea quietly, thinking about a trace of strange information that had appeared in the turmoil in the town these days. Based on his understanding of Mrs. Huang and Cui Dalong, their previous fights seemed to be a little restrained, perhaps taking into account their respective backgrounds and not going all out.

But there are already some signs of "outsiders" in the town, such as Song Zixuan and his elders whom Xia Qi met when he was a guest at Mrs. Huang's, who are obviously not ordinary people.

Who is behind Cui Dalong? Could it have something to do with that wave of killers?

He needs more clues now.

was hesitating whether to find Cui Dalong directly. Suddenly hearing Xia Yu's words, he didn't react at first, but when he came back to his senses a little, he felt a little incredible, Xia Yu had only been studying in the house for a few hours, did he have an idea?

When did the new trap become so well designed?

Xia Yu nodded, the source box of the crossbow of the strong son had been damaged, so naturally he couldn't use it directly, and he couldn't study its structure, and replied: "Well, it's a bit of an idea, but I need a crossbow, it doesn't need to be very advanced, just the most ordinary kind." I...... I think it's a bit of a joke. ”

He thought for a moment, then organized the language and said, "Recently, I've been researching a lot of 1-star organ source boxes...... Well, most of the repairs sent to the organ room have been fiddled with by me, plus what you taught before, and I have roughly figured out the role of the source array structure. The new mechanism I'm going to make doesn't need to change the structure of the source array, it's just the mechanical part. ”

This is normal, the 2-star repeating crossbow on the market does not rely on the source array structure to achieve continuous firing, and only weapons above 3 stars have that ability.

Lao Chen also knew that Xia Yu had been fiddling with various mechanisms for more than ten days, studying the source box, and it seemed that since he broke through the level 2 perception, he had become very obsessed with the mechanism technique.

That's a good thing.

If the injuries suffered by the young master back then were indeed healed, with the talent of a disciple of the Xia family, it seemed that it was common to become a 3-star mid-level organ master. It's a pity that people's minds perceive mysteriously and mysteriously, and I haven't heard of any way to study the essence of perception, maybe after so many years of recuperation, the young master's perception damage has really healed?

Thinking of this, he nodded: "In this world, the mechanism technique is the core of everything, if you have any questions, you can come and ask me at any time." ”

After that, he turned over and rummaged through the big cabinet in the corner, and really brought out a ninety percent new and well-maintained source shooting crossbow!

Lao Chen really did! I knew that my guess was correct......

Xia Yu was a little surprised, nodded and took the source crossbow: "Uncle Chen, I understand, I'll try it myself first, and if I don't understand, I'll ask you! By the way, I still have to use the tools in the machine room."

"You can just enter this casually, just pay attention to safety!"

Although Lao Chen's organ repair shop is not big, the organ room behind it is not small, and all kinds of materials, tools and equipment are also readily available, and he even saw the thermometer and source pen for making the source box mentioned in the book, but there are not many materials such as jade Yin sand, and I think Lao Chen will occasionally repair some ordinary 2-star organs at most.

Xia Yu took the new source shooting crossbow, and as soon as he entered the organ room, he directly dismantled it and found the key part, the crossbow tongue.

With this, the activated source energy can be converted into elastic force and shoot arrows.

Gently rubbing the crossbow tongue shrapnel with his hand, Xia Yu was a little puzzled, it seemed to be some kind of metal in terms of feel and weight, and it also felt like a bit of jade, and the toughness of the material was even more amazing - Xia Yu used all his strength to bend it with both hands in a small arc, and when he let go of it slightly, a huge force suddenly ejected from the tongue.

Could it be some kind of alloy?

"This is the bone of the barren duck beast, the shoulder blade!"

Just as he was confused, a loud voice came from the door, it was Qiangzi.
