Not only that, but this wood can even be burned twice.

The firewood did not lose its ability to burn after talking, but emitted an orange-red flame, and it was obvious that the heat wave of this flame spewing from the furnace mouth was even hotter.

Even more peculiar than this is the off-white firewood underneath.

The pile of wood on top has been completely carbonized and entered the second stage of combustion, and it has just been ignited.

And when this wood is burned, it doesn't look like it's carbonized, it's more like ...... In vaporization?

That's right, Yang Yi felt it carefully, the wood below was really vaporizing very, very slowly, and the vaporized gas had a very strong flame and a more violent temperature.

It's simply amazing.

Yang Yi, who was full of interest, felt the vaporization process of beige firewood more carefully, and found that this kind of firewood contained a lot of energy, and these energies were released at high temperatures, just so that this special energy could cause a stronger combustion effect in high temperatures, so the temperature in the furnace reached a very high level in a short time.

What's more, these two types of firewood burn very slowly, and adding one firewood can burn for a day or two, which is completely different from those firewood on earth.

The forests of the dark world are infinitely vast, and the people of the dark world don't need to worry about the energy crisis at all, a simple piece of wood can supply the fire energy needed for a day, right?

The world and the earth are very different.

……

The furnace was heating up rapidly, and the five master blacksmiths were discussing something while calcining the metal according to their own experience. I hope to be able to make metal materials that meet Yang Yi's needs.

Some people directly use the perfect monometallic material in their minds to calcine, hoping to achieve perfect strength after calcination and quenching. There are also two people who have opted for alloy technology to fuse and calcine new metal materials.

All the metal they processed was handed over to Yang Yi for testing.

Yang Yi is the only person who can do such a test here.

First of all, the metal they created was made into a spring, which was a breeze for Yang Yi.

The first test was a spring made of monometal.

Since this step only tests the strength of the spring. Therefore, all you need to do is add a spring to the gun that Shenmu has changed.

Load, aim, pull the trigger, shoot.

With a bang, the bullet flew out, but the distance was limited, and the bullet flew out less than 100 meters and began to fall in a parabola, such a power is at most the level of a toy, and I want to use it to kill a monster with a huge body. It's a little too tender, unless the monster beast stands there still.

If the thick-skinned monster stood still, it wouldn't be able to kill it.

The second test is a single metal spring, the test effect is not bad, a shot went out and hit the wall of the vestibule compound, and even almost clicked through the wall, such a power is good.

The two tests that followed were not as good as the results of the second test.

The final test was the oldest of the five master blacksmiths, who forged an alloy material, and it was not a fusion of one metal, but a fusion of four metals.

It takes more than boldness. What is more needed is care and sufficient experience, and the proportion of each metal in the addition process needs to be carefully compared.

The fact that he dared to try such a bold innovation at such a young age shows that this old man's heart is still young, and he has more vigor than young people in the career he loves.

Yang Yi added this spring to the grab.

When he was loaded, he felt the strong resistance of this spring. This means that the spring has a very strong thrust when it comes back to rest, and that's what he needs.

After loading, Yang Yi still aimed at the wall of the vestibule compound.

Pull the trigger.

There was a loud bang, and even the sound carried a powerful vibration.

Bullets flew out of the chamber in an instant. The living room, which runs through the atrium, breaks through the wall of the vestibule and continues on.

Out of Yang Yi, no one could see where the bullet disappeared.

Yang Yi didn't see it. Rather, he could feel it, he could feel the bullet flying after it had pierced the wall. After flying a distance of about 600 meters, he began to be powerless, and when he completely fell to the ground, he had already flown a full 700 meters from the place where he was launched.

Yes, this spring is still very good.

"Come on, measure how far this bullet has fired." Howe said excitedly.

He could see that the power of this bullet was not small.

That's what he wants.

"No need, about seven hundred meters." As soon as Yang Yi raised his hand, the bullet returned to his hand, he took out the spring in the gun, looked at it carefully, and handed it to the old man again.

"Uncle, the performance of this spring is very good." Yang Yi affirmed with a smile.

The old man was also excited and surprised by the metal he had created.

But for the strength of the prototype weapon up to 20,000 meters away, 700 meters is absolutely not enough.

So after Yang Yi praised it, he became serious.

"I don't know if the general told you that the parts you are making belong to a weapon used to kill demon beasts from a distance, the so-called long distance, the definition in my mind is the distance that can kill the enemy within any visual distance, and our enemies are those powerful demon beasts, if we see them two thousand meters away, then it is best to be able to kill them at this distance, instead of waiting until they appear within the range we can attack before attacking, then there is no point."

"Master Pony, you want to build a weapon like this?" The five blacksmiths were shocked.

They guessed that the weapon they were going to build would be a great weapon, but they didn't expect that what the master was talking about would be such a weapon.

Kill the monsters as soon as they appear in sight, if such a weapon is successfully made, it will bring a revolution, an unprecedented revolution, it will allow humans to have a stronger long-range attack ability, and there will be a greater safety distance in the face of the attack of the monster, this safety distance does not know how many sacrifices can be reduced, and this safety distance does not know how much they will increase the certainty of victory.

It's extremely exciting to think about.

But this excitement and disbelief appeared in their minds at the same time.

Two or even three thousand meters away can kill a demon beast?

"Master Pony, do you mean a master or do you mean ...... All those with weapons? "This is a very important question.

"All those who have weapons. Every warrior who defended the city. Yang Yi said affirmatively.

At this time, the faces of the five people changed, and they became even more incredulous, as if they had heard an amazing story, which sounded a little fake, but the person who told the story seemed to be able to turn this false story into truth.

This kind of unbelievable expression can be seen clearly on their faces even on a black night like this.

Anyone with a weapon can kill a monster at a distance of two or even three thousand meters, and the changes brought by this weapon will be even more amazing.

It's what they can imagine.

It's also unimaginable to them.

How exactly can such a weapon be done?

Looking at their confused and excited faces, Yang Yi spoke again.

"If you want to achieve what I call long-range lethality, the spring is the key to the key, and all the lethality of the weapon I want to do is mainly generated by this spring, and the more powerful the spring, the more powerful it will bring, and the more lethal it will be. The distance of seven hundred meters is indeed very powerful, but seven hundred meters is only one step away for such a powerful demon beast, and even for flying demon beasts, seven hundred meters is still a rather dangerous distance. ”

"Another very important point, the range of 700 meters seems to be quite long, but the really lethal game is probably only about 300 meters, that is to say, it can cause damage to the target at a distance of about 100 meters, once the distance is farther, even if the target is shot, the damage will not be so great, then the power that our weapons should have will disappear."

As soon as Yang Yi finished speaking, the young blacksmith also spoke.

"But can this really be done, sir? With no energy in this way, can it really do enough damage to the monster? ”

In their understanding, the root of being able to do enough damage to demon beasts is strong energy, physical damage is only suitable for small demon beasts, for large demon beasts, physical damage is just a way to disrupt their actions, and fundamentally it still requires a strong energy output to give the other party fatal damage.

Maybe they haven't tried, or maybe they haven't tried it successfully, and they don't seem to know that it's just because they didn't get enough physical damage.

Also, the longest weapon in the hands of humans is no more than two meters, while the body of a demon beast is tens of meters or hundreds of meters, and the flesh is more than two meters thick, and it can't die at all if you stab it.

Yang Yi smiled, intending to use his actions to tell them whether the truth was true or false.

He walked to the middle of the compound and took out his own gun and aimed it at one of the last monsters in the sky.

"Look, if the strength of the spring is strong enough, the power it can produce is unimaginable, as long as this power is strong enough, no matter how powerful the demon beast is, it can be killed, and the operation of such a weapon, even without how strong the strength is, any guard on the city wall can do it."

Aim for the beast's head.

"Bang" with a loud bang, the bullet through the protection over the city directly hit the head of the huge monster in the distance, without any pause, the monster beast directly lost its life, smashed vertically on the protective shield above the city, and slid down the protective shield towards the outside of the city, and a group of demon beasts with lower strength immediately pounced to absorb this rare feast.

All this happened right above everyone's heads.

All five blacksmiths were shocked.

Yang Yi told them the power of this weapon in the most direct way. (To be continued......)
