It turned out that Li Cheng and Gu Hongyuan bumped into each other unexpectedly.

And Yang Kaiming didn't care about these at all, after turning off the light, he immediately took off his eyes, wiped his eyes in disbelief, and then put them on again, and after being stunned for a while, he broke out into wild laughter:

"Haha...... Ha ha...... So that's ......"

Looking at Li Cheng and Gu Hongyuan's appearance again, he was once again overjoyed, looked around with his glasses, then turned on the light, and handed the glasses to the two of them with a smile.

"You two, look at it, it's amazing."

What kind of person is Yang Kaiming, he has always been calm, he will never be a casual person, he now says that this thing is magical, and the two naturally have no doubts.

Of course, the three of them are inseparable from each other, and Xu Ziling hurriedly helped Li Cheng and the two of them to debug it, so in the next time, the command center entered the rhythm of turning on and off the lights.

If the three of them get a child with their favorite toy, after testing a few functions, they immediately can't put it down and are reluctant to put it down.

"How long does the battery last?"

After playing handsome, I finally got down to business.

"In the wireless state, it can only be used for three hours, which can basically support a war, but in an emergency, you can use wired, but in this case, the tactical watch is not easy to carry in your hand."

A few people nodded.

What Xu Ziling said, they all understand.

The tactical watch was originally carried on the hand, and once the number jù line was connected to the glasses, the number jù line would affect the action, and the tactical watch was the most suitable to put in the pocket of the tactical suit.

"Three hours, it's basically no problem, in the state of night fighting, if the operation hasn't ended in three hours, it must be in big trouble, and if it's really that situation, it doesn't have much to do with this thing. Besides, it might be a little more cumbersome to use in my pocket, so I prefer to keep it in my hand rather than carry it on my hand......"

"Well, it's a little more troublesome to put in your pocket, but it's more useful when using glasses, so it's really an easy choice......"

……

Several people said so, Xu Ziling naturally had no opinion, thought about it, and said: "If you use it with glasses, do you think that the current tactical watch is a little unsuitable?" I'm talking about form, control. ”

"When you say that, I really think that's the case, most of the functions can only be controlled by the tactical watch now, but the screen of the tactical watch is a little too small, and if you put it in the tactical suit, it is a little inappropriate now......" Yang Kaiming quickly took over his words.

"This does make sense, because of the problem of size, the tactical watch is designed to be small, most of the control is also touch-type, and it is also limited to the screen is too small, and sometimes there will be mistakes, now with the tactical multi-function glasses, you don't need to look at the tactical watch often in the future, and it is suitable to improve it."

After a few words, the facelift of the tactical watch became a foregone conclusion.

Of course, Xu Ziling can't take back the few sets of samples that he took out, and the three of them are now like treasures, where will they return them to him?

However, the matter of the facelift is not very urgent now. After all, tactical watches also have certain advantages, in the case of no matching glasses, the style of tactical watches is the most convenient to use, and all personnel will not be equipped with multi-functional glasses for the time being, so this matter does not need to start immediately.

Complete the tactical glasses, and the next step is body armor.

In the past, when developing individual combat armor, nanomaterials were used for bulletproof coatings, and the effect was very good, but the cost of that thing was too high, and it was impossible to equip it on a large scale.

The individual combat armor is somewhat special in terms of volume and appearance, and is not very suitable for performing conventional tasks, so the body armor alone is a necessary equipment for individual soldiers.

Body armor is not what ordinary people think, it only needs to have bulletproof function.

The design of the appearance, fabric, and style is actually equally important.

And body armor is not a single type, each branch of the army has its suitable body armor, like the military factory operations personnel, of course, it belongs to the special forces series.

Especially like the special forces individual combat carrying gear that is now commonly used in China, it not only contains the body armor itself, but also includes the combat carrying carry, water bottle bag, gas mask bag, training bag, various magazine bag modules, radio bag modules and so on......

And what Xu Ziling is getting now is such a complete set of combat carrying equipment, strictly speaking, it can't be called body armor at all.

The accessories are all based on the equipment configured by the troops, and these can be obtained later, and the most important thing is, of course, the body armor itself.

In terms of the 06-type individual carrying equipment, its body armor is composed of the body, crotch guard, neck and shoulder guard, throat guard, pistol sleeve leg pendant, and dagger set.

The biggest difference, of course, is in the bulletproof material.

In fact, the biggest role of body armor in modern warfare is to protect grenades or bombs, explosives and pistol bullets, and it is basically impossible to achieve no casualties under rifle hits.

This is impossible not to say that the body armor can not prevent the blow of rifle bullets at close range, because there are three levels of standards, which can basically prevent most rifle bullets, mainly at close range, the kinetic energy of rifle bullets is very large, and body armor can only prevent bullets from penetrating and then hitting the human body, but it cannot completely eliminate the kinetic energy brought by the flight of the warhead.

That is to say, even if the bullet does not bring direct damage to the body, the kinetic energy brought by the bullet hitting the body armor can completely injure a person, and the lucky ribs are broken, and the unlucky direct internal organs are damaged by the bones, and then bleed to death in a short time.

Xu Ziling, like the lion, the main problem of the new body armor they are considering is how to eliminate the kinetic energy of the warhead, rather than the simple bulletproof function.

The Lion's scheme is very well thought out in this regard, the main material is a new type of fiber, which no longer needs a splint like traditional body armor, but can directly use an outer layer of less than a centimeter to block bullets.

Of course, the splint was not canceled, but the ceramic splint or steel plate was replaced with a liquid inner layer.

Unlike the bulletproof function of the original splint, this liquid interlayer has no bulletproof effect at all, and is completely used to eliminate the kinetic energy of the bullet.

The bulletproof layer originally had a certain effect of eliminating kinetic energy, coupled with this layer, the lion's report explained that the new body armor can prevent 7.62*51 steel core bullets with a bullet speed of 800m/s at a distance of more than 10 meters, that is, various ammunition fired by AK and 56 rifles, and people only have a few kilograms of force.

Usually body armor at this distance, suffering from this caliber of ammunition, as long as it is a slightly more important part, the base person is hopeless, the new gadgets made by the lion can have this effect, Xu Ziling is greatly interested.

Without saying a word, the development of new materials began immediately.

After five busy days, the first body armor came out.

The size was made according to his own height, and when he looked at the first finished product, he immediately put it on, "It feels okay, the total weight is less than 1.5 kilograms, not bad......"

"What I designed, can there be anything bad?"

The lion immediately appeared and said triumphantly.

"Well, a lot of credit." This time, Xu Ziling did not raise the bar with the lion, but praised him sincerely.

There is no pendant yet, just a bare body armor, nothing to try, it feels quite comfortable, he takes it off, and then goes out.

The real yàn room here in Makula is not like Star City, it is purely a technical real yàn room, there must be no place to test the gun, and when he got out of the real yàn room, he drove outside and went directly to the shooting range.

Halfway through the car, he thought of Yang Kaiming and them, and called them again.

With the last tactical glasses, of course they also knew about the body armor, and when they heard that the new body armor came out, several people said that they would come over immediately.

There was no professional testing equipment at the shooting range, and when he arrived at the shooting range quickly, he could only ask people to find a bottle of water, and then tied the body armor to it, ready to come to the test.

"Find all the guns we have here, and if you have a steel core bullet, you can take a steel core bullet, and if you don't have it, you can take an ordinary bullet."

"Yes!"

Guns were delivered quickly, even for the most powerful tigers.

Xu Ziling can be sure that this thing will definitely not be able to stop the tiger, but it doesn't hurt to give it a try, put good bullets on the gun, and Yang Kaiming and they will come.

"How?"

With the experience of tactical glasses, several people asked Xu Ziling as soon as they got out of the car.

"I haven't tried it yet, I don't know, each person will try one shot, come, try the pistol first."

Yang Kaiming and the others immediately picked up a pistol and bullets from the box, and when they saw their distance and the bullets in their hands, they were all surprised.

"It's less than ten meters, I still believe in the steel core bullets of Nine-two and USP, and even the Desert Eagle also uses steel core bullets?"

Ninety-two and USP are both nine-millimeter calibers, but the desert eagle in front of them is .50, that is, 12.7 millimeters, and ten-meter distance body armor can prevent nine-millimeter steel core bullets, which is easy to accept, but 12, 7 millimeters makes people a little hard to believe.

This thing is more powerful than a normal rifle at close range.

Hearing this, Xu Ziling shook his head, "Try it first, this is not a rifle bullet after all." Theoretically, it works, but I don't know if it's specific. ”

"Even if you can block it from this distance, it doesn't mean anything." Li Cheng on the side said.

Obviously, I also thought of the huge kinetic energy brought by the 50 bullets at close range.

"Hehe......" Xu Ziling smiled and said, "You think I'm such a superficial person?" ”
