Starting from the awakening of the blue silver grass

Chapter 50 Transforming Guns and Bullets, Yellow Water of Destruction
"Senior Dugu, how powerful is this blow?" Gong Teng lowered his gun and asked.

At the same time, his gaze stayed on the bullet fragments.

This single metal bullet is still not hard enough.

If he can have enough money, he can purchase enough materials.

Just build a modern smelting furnace and use it to smelt high-hardness alloys.

Or there are enough people to help him mine all over the world.

In this case, you might be able to find the so-called hardest metal in the world.

铬！
Although, the melting point of chromium is only [-] degrees.

However, the hardness of this metal is nine.

What's more, Gong Teng only made ordinary bullets, not the really powerful bullets such as Dum bullets, armor-piercing bullets, and high-explosive bullets.

It's not that he can't do it, but that he feels that the master-student relationship with Dugu Bo has not been formalized yet, so he needs to save it for himself.

"call……"

At this time, Dugu Bo let out a breath, and there was a green light beating in a pair of dark green eyes.

He was really startled just now!
That bullet, if it wasn't hard enough, might have pierced through his defensive spirit ability.

Afterwards, Dugu Bo thought about it, felt the power of the bullet just now, and the hardness of the bullet, and then came to a conclusion.

"This blow is very powerful. Even if a soul saint of the assault department casts his martial soul avatar, it may be difficult to save his life. It also poses a certain threat to Contra. Even if the material is not hard enough, even the old man may not It's going to bleed..."

Dugu Bo gave a very high evaluation.

At the same time, he also started to look at Gong Teng for this kind of firearm.

Because the power of this thing is really strong!

"Is that so, then I have counted." Gong Teng nodded upon hearing the words, and said.

The short-barreled bullets of ordinary bullets have this power.

If it is replaced with a long tube, the gunpowder filling amount will be doubled, and the power will be stronger.

For Gong Teng, this is very simple.

It only needs to slightly modify the three firearms, and increase the length of the shell case.

It's just that in this way, the revolver may have to change its name.

A revolver that can be filled with long-barrel bullets of 12.7mm caliber might as well be called a hand cannon.

Moreover, the warhead can also be transformed into other models.

For example, the bullets of revolvers are usually only used at close range and do not require too high precision, so you can use dum bullets directly.

Long barrel shells, dum warheads!
Gong Teng felt unwilling to say that he couldn't beat the soul sage, so he had a chance to find a soul sage to try.

There are also sniper rifles, which have to use standard long-barrel shells and armor-piercing warheads.

The penetrating power of the armor-piercing bullet is much stronger than that of the Dum bullet.

Moreover, this kind of armor-piercing warhead has the effect of breaking the inner family's qi.

In addition, Barrett has always been known as the king of long-range sniper killing. He is not an assault weapon at all.

If it is used to snipe and kill a high-level soul master, it takes only a split second, and the opponent may have been headshot before he even has time to use his soul skills.

A soul master who has not used soul skills, even a Contra who is possessed by a martial soul, will definitely not have too strong defense, but whether he can kill Contra or not, he still has to find a chance to try, after all, only Real knowledge comes from practice.

As for whether he could kill the Titled Douluo, Gong Teng didn't think too much about it.

Because, Title Douluo's spiritual power is generally very strong, covering his surroundings at any time.

No matter how fast the bullet is, it may not be able to snipe before the other party has no reaction, and once the Title Douluo has a momentary reaction, there will be no chance to snipe.

A powerhouse at the Title Douluo level, very powerful.

Moreover, not only attack and defense, the speed is also amazing.

It is really difficult to kill a character of this level, unless you use a powerful weapon.

For example, a sniper gun, lengthening the shell, strengthening the warhead, in addition to making some manipulations to the inside of the 25mm super-caliber warhead to make it into a highly lethal high-explosive bomb.

Then, when Gong Teng's mind was thinking.

Dugu Bo stretched out his hand in front of Gong Teng, and said, "Give this short-handled weapon to this old man, and this old man will give it to Yan Yan for self-defense."

Dugu Bo didn't ask for a spear, maybe he thought it was too bulky.

But the short-handled revolver is different.

This is simply a melee artifact!

Dugu Yan is Dugu Bo's only relative.

As long as Dugu Yan is equipped with such a weapon.

If you encounter danger, you can save your life at a critical moment.

Is it for Dugu Yan?
Gong Teng thought for a while, and immediately removed the bullets from the revolver, and took out another 25 rounds. After collecting [-] rounds, he modified them, transforming the bullets into powerful dum bullets.

Although it is still a short-barreled shell, the Dum bullet is far more powerful than ordinary bullets. It may not only kill the Soul Emperor, but also cause fatal injuries to the unsuspecting Soul Sage.

"Changed to this shape, will the power of the bullet be stronger?" Dugu Bo asked very curiously.

"That's right, this kind of bullet is called Dum Bullet. It is more powerful, but its accuracy will be reduced. It is suitable for use in close combat, and the closer the distance, the better. It is strong and accurate within seven steps."

Gong Teng nodded, and responded to Dugu Bo's question while busy.

Immediately afterwards, Gong Teng taught Dugu Bo how to load the dummies, how to open the lock and how to disassemble the wheel.

"Why are there only [-] pieces? You're too stingy. Give me another [-] pieces."

After Dugu Bo learned how to use it, he looked at the bullets that Gong Teng gave him, and immediately said dissatisfied.

Thirty bullets are enough for who!
What if the precious granddaughter encounters many enemies? !

"Three hundred, how dare you want..."

Hearing this, Gong Teng secretly thought in his heart, and at the same time he glanced at the barrel of the revolver.

This is just a barrel made of ordinary refined iron, which can withstand continuous firing of [-] rounds of bullets.

"No, I don't have much nitric acid in my hand. Unless you go to the Star Dou Forest for me and retrieve all the nitric acid I found there, then I will make you [-] bullets."

Gong Teng took out a map, which marked the location of the caves that produced nitric acid.

"Hmph, brat, who do you take this old man to run errands for you every day?"

Dugu Bo suddenly said very dissatisfied.

However, he still reached out and pulled the map from Gong Teng's hand.

Afterwards, Dugu Bo turned around and was about to leave.

However, in the next second, Gong Teng grabbed the corner of his clothes again.

Gong Teng pointed to a city sign on the map and said:
"By the way, if you drop by, senior can go to Soto City. There is a shop opened by a soul sage. There are many abandoned soul guides in the shop. It's just that the shopkeeper's price is too high, but if you go, you can find the price It should be very cheap, and it may also use the technology of the soul guide to treat the poison of the Jade Phosphorus Serpent Emperor on your body."

"I know, I know, you kid really treat this old man as an errand for you, it's outrageous!" Dugu Bo flicked his sleeve robe angrily, and swung Gong Teng's hand that was holding the hem of his clothes away, and immediately flew into the air, his figure In a flash, it turned into a green glow and burst out.

Looking at its flying direction, it is clearly the direction of Tiandou City.

"Dugu Yan, who got the revolver, will accidentally kill the third brother?"

Gong Teng watched Dugu Bo disappear into the sky, touched his chin immediately, and murmured to himself.

If he remembers correctly, in a few months, the Huangdou team will go to Soto City.

It's a pity that he is very busy, otherwise he can go and have a look.

The collision of hidden weapons and firearms must be very interesting.

What's more, he is also very greedy for the dragon's beard needle on the third brother's body.

If we can't get some of this kind of naturally occurring closed-element acupuncture, it would be really itchy.

Afterwards, Gong Teng began to modify the firearms and bullets in his hand, and took the time to build a new large-caliber revolver.

After the modification, Gong Teng was equipped with two large-caliber revolvers, a Barrett sniper rifle and a super-large-caliber sniper cannon.

In his hands, there are two large-caliber revolvers with extended wheels, and the bullets are modified 12.7mm caliber dum bullets with long-barrel shells.

bang bang bang...

Gong Teng started firing his gun at the sky to test how strong the bullet's anti-shock power is.

As a result, when Gong Teng was testing, he found that the material of the revolver itself was not strong enough. After firing a few rounds, the revolver was actually cracked by the shock.

In desperation, Gong Teng had no choice but to take out some good materials, and borrowed the water of red soup from the Ice and Fire Liangyi Eye to smelt and fuse the metals.

I saw that Gong Teng made an earthen kiln, channeled in the red soup with the eyes of ice and fire, added combustion-supporting substances, and turned the bellows to forcibly raise the temperature to an extremely high level.

Although I don't know how high the temperature is, it should be over four thousand degrees.

After all, even some rare metals with relatively high melting points were smelted into liquids.

He used this rough doping method to barely produce a new alloy with a passable purity, which was used to make new firearm parts.

After a while, Gong Teng produced a batch of new alloy firearms.

Two large-caliber revolvers are assembled with 12.7mm caliber dum bombs with long-barrel cartridge cases.

The Barrett sniper rifle is equipped with a 12.7mm caliber armor-piercing bullet with a long-barreled case.

In the end, the large-caliber sniper gun, which can be called a heavyweight weapon, uses 25mm high-explosive bullets with the same extended casing.

It's just that the inside of the warhead has not been filled with high explosives.

If it is a high explosive, the best choice is naturally Tritonal.

That is, a mixture of trinitrotoluene and aluminum powder, an explosive whose power is several times that of TNT.

Or nitroglycerin, the power of this thing is not weaker than Tritonal, but the stability of nitroglycerin is too poor, and it is easy to explode.

This thing is called, the yellow water of destruction!
If there are too many explosions, its power can wipe the ground.

In fact, nitroglycerin is very easy to prepare.

Nitric acid is added to sulfuric acid to form a mixed acid.

Adding glycerin to mixed acid is nitroglycerin with poor stability and strong explosive power.

"Wait, if I engrave a miniature space array inside the warhead and then fill it with nitroglycerin, then no matter how violently the external warhead vibrates, it will not affect the nitroglycerin inside the space array, so it will be stable. "

Suddenly, a light flashed in Gong Teng's mind.

But in the next second, he encountered another problem.

Stereically stable and nitroglycerin stable.

So when the warhead hits the enemy, how to make it detonate automatically?
Gong Teng took out a 25mm super large caliber bullet from his pocket, squeezed it in his hand and played with it for a while, and immediately his eyes showed a thoughtful look.

"The impact is dislocated, and the formation collapses. At the same time, primer and gunpowder must be placed, just like the structure of a grenade, so that the nitroglycerin can be detonated."

Gong Teng thought for a while, and immediately began to modify the high-explosive bomb in his hand.

He disassembled the warhead, made a hollow structure inside, and immediately embedded a crystal stone engraved with a miniature space formation inside.

The top of the crystal stone, that is, the position inside the top of the bullet, was reserved by him for a firing pin, which is used to displace the bullet when hitting the target so that the firing pin can penetrate the crystal stone.

Moreover, there is a safety primer at the bottom of the crystal stone, and the entire warhead must be filled with flames.

At that time, after this high-explosive bomb hits the target, the warhead will be misaligned with the projectile body due to the strong interaction force, and the firing pin at the top will directly pierce the crystal stone, causing the formation to collapse. Primer on.

In an instant, all the nitroglycerin in the formation will be exposed to the ignited gunpowder.

"Do a few more experiments to test how the crystal stone will not be shattered by the powerful kinetic energy of the bullet, and ensure that the firing pin can directly pierce the crystal stone and the primer to detonate the explosives smoothly."

While talking, Gong Teng first installed a shock-absorbing device on the crystal stone.

Afterwards, Gong Teng began to test one shot after another.

boom! !

The 25mm caliber extended high-explosive bomb is very powerful.

With one shot, those towering trees in the distance were all shot through dozens of holes the size of a basketball in an instant.

Gong Tengfei went over to collect the broken bullets, and then went to check the internal conditions.

Finally, after ensuring everything was done, he began to carefully refine the nitroglycerin.

The extraction of glycerin is very simple. When Gong Teng uses calcium carbonate to make soap, a large amount of glycerin can be produced, and a can is collected in a short time.

He then used a test tube specially designed to introduce the solution.

Through air resistance, nitric acid and sulfuric acid are carefully mixed together to make a mixed acid, which is then slowly injected into glycerin.

During the whole process, Gong Teng almost held his breath, because he was also really scared.

If this explodes...

It seems to be ok...

After all, Gong Teng still has the soul bone of the Blue Silver Emperor to save his life.

Soon after, Gong Teng extracted a portion of nitroglycerin.

And, he slowly injected it into the space formation inside the high-explosive bomb.

Since more nitric acid would be available immediately, Gong Teng simply lost his mind and prepared all the nitric acid into nitroglycerin and injected it into the space magic circle.

The amount of nitroglycerin produced by this last bit of nitric acid is not much, only more than 1000 milliliters, it can't even fill the space in the array, it can only be suspended into a ball of silent liquid.

In the end, Gong Teng painted the high-explosive bomb red and drew a skull to show that it was a dangerous bomb.

"Such a bullet should be able to threaten Title Douluo..."

Gong Teng stroked his chin and said in estimation.
