As for the remaining few permits, it can only be said to be a special situation, this unexpected situation Zheng Chen himself can't figure out, there are always some dust crystal bullets that will suddenly explode when they are used, even if he has adjusted their proportions to the level of absolute safety.

Of course, the lower the mixing ratio, the lower the likelihood, as for why this happened, it can only be said that the dust crystal thing was originally the reason for the instability, and he still didn't have too deep a understanding of the technology in this region.

Except for these subtle factors, on the whole, the bullet is still safe!

Well, after all, this bullet has a lot of dust crystals to use, and the cost is very high, and if you want to use it as the kind of ordinary bullet in the machine gun that can be changed to a shuttle at will, it can probably only be used by a local tyrant like Weis.

However, although the handle of her weapon has a part that looks like a revolver, and even a firing pin, it still can't shoot a gun, and it is filled with dust crystals, which can allow her to exert the power of different attributes.

On the other hand, other people's weapons can basically be used as guns...... Strong. With the exception of Ark, his weapons are more primitive, and they look like they're just family heirlooms, simple swords. "Oh...... Sure enough, it was not what I expected. Opening her ammunition box, Nora looked at the grenade contained in it and shook her head slightly, took out a grenade and looked at it in front of her eyes, feeling its weight, "It feels good!" ”

"I don't know how powerful it is!" Ruby looked at her bullet box, opened it and looked at it, and there were two kinds of bullets inside, one of which was more numerous. But the other is very rare, only eight rounds. Same magazine size as her weapon.

The bullets she asked for were of a large caliber, and according to the needs she had described. The explosive power of the bullet was deliberately strengthened, and the gunpowder used was also red dust crystal gunpowder, which was more powerful but would increase recoil, and she and her look ...... No, it's obviously not a mom-born blonde sister who is quite fond of the recoil factor.

Taking out a bullet painted black and looking at it, Ruby held it up to her fingertips, "Why are there so few of them?" Isn't it special? ”

Zheng Chen nodded, "If you can, pay attention to recovering bullet casings and bullets, they are very precious." ”

He found that dust crystals could conduct with many materials. Moreover, the strength of the metal material carried is too high, although it will restrain the range of damage caused by the dust crystal bullet hitting the target, but it can exert a condensed single attack effect.

However, this material needs to be tested, such as red dust crystals, if the strength of the carrier body after detonation is high enough to restrain the power of detonation, then the bullet will instantly become extremely hot, and it can easily evaporate and burn the first object it touches.

The green wind attribute is not suitable for uniform fusion of high-strength carrier bullets, so it will not be able to exert any strong power at all. But if you can use a clever way to make the green dust crystal spiral and divide it on the bullet, that's another matter.

Because the bullet shoots out at an extremely fast rate, it is in the condition that the carrier can withstand it. The proportion of mixed dust crystals is not high.

Even if it was the moment of impact, it stimulated the dust crystal in the bullet to explode, and the bullet that wrapped the dust crystal after the explosion had already flown out at that time. The disadvantage of this is that it is better not to shoot continuously, which can damage the gun greatly.

This is especially true when using high-strength dust crystal bullets with lightning properties. It is possible that the bullet flies out, but the current conducted on the weapon also injures itself.

"Hmm...... I really want to try it! "Look at the bullets that come in a variety of colors. Ruby narrowed her eyes slightly, the bullet was red overall, with green spiral lines on it, consistent with the rifling of the firearm built into her weapon, "Two dust crystal attributes? ”

Looking at her expression, it seems that she feels less!?

"Actually, you can add the lightning attribute." Zheng Chen thought about it for a moment before he said, and then shook his head again, "This kind of bullet has a lot of wear and tear on the gun, I haven't done it many times, what you have in your hand is a real finished product." ”

"And the words of the two attributes...... Enough is enough. "It's not impossible to mix one more, but the harm is really overflowing, and there is no need at all!

The wind attribute part of the spiral form will produce a wind drill form with the spiral pattern after excitation, and the power of the dust crystal is very magical, and the high-strength carrier makes the power of the two dust crystals excited at the same time without bursting.

In this regard, Zheng Chen also deliberately reduced the content of dust crystals, but the single killing power of this bullet is the strongest!

As long as it is a living body, it is broken, and it will have to face the strangulation of wind cutting and the super high temperature damage contained in it, and this carrier material is naturally that special metal, because that kind of metal cannot be replenished, so Zheng Chen will say so.

"Use it as the hole card for the finale."

"Uh, my crescent rose really won't go bad because of this?" At the mention of his weapon, Ruby's attitude suddenly became tense.

"It's okay to use one or two in a short period of time."

Zheng Chen has come into contact with her weapons, and the material of her weapons is also extremely superior, so the bullets of this ruined gun can be used to achieve the level of non-damage, of course, in case of a whim, she will directly do it...... That weapon might really need to be properly maintained.

"Then why isn't there mine?" At this time, Nora suddenly raised her hand, shook the grenade in her hand, and complained about Zheng Chen's special treatment.

"This bullet doesn't burst."

"Huh?" Nora tugged at the corners of her mouth with a somewhat exciting expression, and the ammunition that didn't explode was definitely not suitable for her weapon.

"Oh? What about us ......"

Everyone else also noticed that their ammunition box also contained ammunition similar to Ruby, but the color of the bullets was much lighter, and the power was conceivably much worse, but there were quite a few of them, these were just ordinary metals mixed with special metals, but the proportion of dust crystals was reduced, and they could also bear the power of dust crystals after they were excited.

Moreover, the guns built into their weapons are all machine gun types, and the consumption of bullets when strafing is even more useless!

"Mine is not either, alas?"

Yang Xiaolong looked at his own ammunition here and shook his wrist, "Because it's too close to your arm?" ”

Zheng Chen glanced at the bracer she was wearing on her arm, and nodded slightly, this bracer was a pair of gauntlets that could shoot bullets, because it was too close to her hand, and the bullets used by her weapon were not suitable for that type of dust crystal bullet.

There are two types of bullets she requires, one is a shotgun and the other is a solo bullet, the production of the shotgun made Zheng Chen think about it for a while, and the final way is to present the warhead in a three-layer isolation way, so that each projectile will be in close contact when not in use, even if it is affected by the impact, it will fly out evenly under force, rather than which of them will be stimulated too much first, resulting in a chain explosion......

"You've worked hard." Seeing that his classmates were very satisfied with his things, Wei Si rarely didn't directly ridicule, to be honest, the dust crystals that he directly threw to Zheng Chen at the beginning were also full of anger, and he regretted it a little after thinking about it, why did he make such a loser act on impulse?

"The enhanced Dust Crystal Bullet can be remade by me after the recovery of the cartridge case and bullet, or you can provide high-strength load-bearing materials." Zheng Chen's face did not change, and said, "Dust Jing is currently free, other fees are charged, and the working hours are from half past six to half past seven in the afternoon, and it is outdated." ”

"Hey? Still a big name? Wei Si raised her eyebrows, wanting to say something, but saw Ruby rummaging through the bag brought by Zheng Chen, and took out a box from it, and the coat of arms attached to it made the corners of her eyes jump, "What?" And mine? ”

"That...... What about mine? "Strong. Ark raised his hand weakly.

Zheng Chen glanced at the 'simple' weapon on his waist, "Can you use it?" ”

"Ahem...... Don't. He sneered that his weapons were antiques compared to the weapons of his teammates and classmates.

Noticing a line of sight behind him, Zheng Chen looked back, and the tall boy who had had a conflict saw him turn his head and clench his fist defiantly.

Strong. Ark was a little worried, "Well, the next lesson is gladiatorial training, you seem to be careful?" ”

His face was a little bad, and he had been bullied by the other party during this time.

"Your fighting skills are terrible, come to me after eating." Zheng Chen still said with a cold face, "It's a special compensation without your share." ”

At the beginning, she received too much dust crystals from Wei Si, since she wanted to take care of her classmates, Zheng Chen, who is currently very idle, didn't mind spending more effort on this, and he had also visited the library of the academy many times during this time, but he didn't gain much, this place didn't have what he was looking for, but he couldn't leave here at the moment.

Looking at Zheng Chen's expressionless cold face, Qiang. Ark couldn't help but swallow his saliva, feeling a little trembling all over his body, "Are you going to abuse me?" ”

What frightened him was that Zheng Chen nodded and replied, "That's right! ”

“…… Can I refuse? ”

"It's a pity!"

"Oh ha! Come on Captain, let's have a fierce collision between men and beat him hard! "I slapped it hard. Ark's shoulder, Nora clenched her fist tightly, "Just think about it, my fist starts to tremble!" ”

"I, I thought I was going to die a terrible death." opened his mouth and looked at Zheng Chen's precarious appearance. Ark felt his liver tremble.

"Come on." Phila also reached out and patted him on the shoulder.

"Come on." Lie Lian nodded faintly.

"You ...... Don't bring this! (To be continued.) )
