"What is the plugboard?" asked Berry, looking puzzled. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

"Hehe, the plug-in is the murderer who makes your knife roll the blade, this is it" Lu Ya took the explosion-proof suit in his hand and looked at it slightly, and found the plug-in plate, and then removed the shoulder guard plate on his shoulder from the explosion-proof suit.

This is a piece of black, somewhat reflective oval guard, in order to fit the shoulder, so there is some curvature, held in the hand is not gold and non-wood, although a little weight but not heavy.

Berry reached out and took the board, put it in his hand and rummaged through it for a while, but found nothing, wondering what it was made of, and how it could be so unscathed under his own slash.

"I don't know what kind of material this plug-in board is made of, but it is definitely much harder than steel, let's continue to experiment, see where its limit is, and also position it for future use."

After listening to Ruya's words, Berry nodded in agreement, he knew that this was the main thing.

After a while, the explosion-proof suit was placed, this time the explosion-proof suit was hung directly on a cement low wall, this time the test was an AK47 rifle, the penetration of 7.62 bullets is undoubted, at least Lu Ya did not have the luxury of expecting the surface of this explosion-proof suit to prevent AK47 from shooting at close range.

This is not to say that Berry's attack is inferior to the bullet fired by the AK47, the bullet of the AK47 and the punch of the Brown are not comparable to the two categories of kinetic energy and potential energy of mechanical energy, respectively.

This time it was Ruya who shot him, he took an empty training gun, directly filled it with a pull back charm, and then pulled the bolt to the end.

"Da Da Da ...

After a few seconds, Ruya stopped shooting and threw the AK47, which was still emitting green smoke, to the soldier next to him, and he himself walked over first, followed by Bai Lifu and Xiao Qi.

Luya's firing position is only twenty or thirty meters away from the explosion-proof suit, it can be said that the power of AK47 has been exerted to the maximum, when Lu Ya came to the explosion-proof suit, the first thing he saw was the dozens of warheads on the ground that had been deformed, compared to the non-reflective dark green explosion-proof suit, these warheads are indeed very conspicuous.

Then it was time to check the results, and at this glance, Lu Ya immediately had a smile on his satisfied face.

I saw that in the chest and abdomen of the explosion-proof suit, I could clearly see more than 20 disorganized dents, the surface fabric on these dents, all of which had been damaged without accident, but the inserts covered by the surface fabric did not without exception block all those bullets outside, and there were only one crater or two millimeters deep on the black inserts, which was nothing compared to their average thickness of two or three centimeters.

"Wow~ This kind of clothes are so powerful, Uncle Berry, look at it, none of them have been pierced" Xiao Qi chirped and pulled Berry's arm and shouted.

Hearing this, Bai Lifu also nodded with a hint of a smile, it was really not easy to make him laugh on such an occasion.

"It seems that AK47 can't do any damage to it, go and bring a steel crossbow," Ruya stared at the bullet marks for a long time before ordering.

There were only so many weapons he could use for experiments, and when the AK47 ran out, there were only steel crossbows, bazookas, and Barrett left.

Barrett's attack power Rua never questioned, he felt that it was not interesting to use Barrett to test the strength of the explosion-proof suit, and how to fight and how to wear it could experiment with something. As for the rocket, if the rocket you summoned is an AP bomb, then you don't have to try it at all, the AP rocket can penetrate the tank armor, if it's a HEAT bomb, then you don't have to try, it's a professional armor-piercing shell, if the AP can still leave a whole corpse for the explosion-proof suit, then the explosion-proof suit is estimated to be left with no bones if it is hit by heat.

It's a pity that the rockets summoned by yourself can't choose their own ammunition like Barrett, and they are not either of the two types of ammunition they are equipped with, but relatively ordinary high-explosive ammunition, which is somewhat inconsistent with the name of the anti-tank rocket of the RPG itself.

However, it is undeniable that although the lethality of this ammunition is insufficient, the group attack performance is still good, otherwise it would not have caused such a big result in the last attack of the Kuishan tribe. Therefore, it is somewhat inappropriate to use it to experiment with explosion-proof suits. So Ruya decided to use a steel crossbow to test it first, and if it really didn't work, he was thinking about other things.

The steel crossbow was quickly carried into the field by the soldiers, and this steel crossbow was not the same as the steel crossbow used on the city walls today. This steel crossbow was lifted directly from the research institute, originally about one meter high, three meters long, the steel crossbow with an arm spread out for nearly four meters has been transformed by the iron research institute The length and width have increased a lot, and the arm span has reached about 5 meters, and the bowstring is also the steel wire of the latest formula of the research institute, and the steel crossbow that exudes a cold steel breath seems to give people a sense of oppression.

"This steel crossbow must have been brought from the research institute," Lu Ya said to himself as soon as he saw this steel crossbow, he had seen this steel crossbow that had not yet been formed at that time in the research institute.

"Yes, Patriarch, I just heard that the Patriarch needed this steel crossbow for testing, so I took the initiative to bring this steel crossbow here" The Iron Old Man's voice sounded from beside him, and Lu Ya looked sideways, it was the Iron Old Man with messy hair.

"Hehe, Uncle Tie, why are you here, it's really not easy to see you outside the research institute" Lu Ya hadn't been to the research institute for several days, and when he was there before, he couldn't stand it and urged the old man to pay attention to his image and personal hygiene, but he didn't expect that after only a few days, the old man returned to the appearance of this mad scientist.

"I heard that the patriarch has a new treasure, so I came to prepare to study and study it, but I didn't expect to meet a soldier who was going to carry a steel crossbow on the way, so I decided to get this test object without permission" The iron old man said this, his eyes began to sweep around, and then he was immediately attracted by Barrett, who was carrying a big bear next to him.

Xiong Da, who was originally looking at the steel crossbow being installed in the field, seemed to feel something and immediately turned back to look at the old man Tie, and then the old man's red fruit eyes made Xiong Da immediately vigilant, tightened the strap on his shoulder, and Xiong Da unconsciously moved away from the old man Tie.

"New baby?" Ruya immediately understood after listening to the old man's explanation, and then looked at the way he looked at Barrett, and then smiled bitterly.

"Uncle Tie, just take a look at that Barrett, just our current little water, there is really nothing to learn from, AK47 we can't learn much, don't fight Barrett's idea"

"Well, I'll take a look, just take a look," the old man said absentmindedly, still staring at the bear-sized Barrett. He also knew that he probably wouldn't be able to learn anything from Barrett, after all, the current research institute hadn't even developed a flintlock pistol, and the revolver and AK47 were already looking up to them as an existence, but as a workaholic with an almost paranoid focus on scientific research, how could the old man of iron let go of such a powerful weapon that he had never seen before before when he looked at it closely.

Seeing that the old man was like this, Lu Ya pursed his lips and said nothing, turning his head to look at the steel crossbow that had been assembled.

After the steel crossbow was assembled, the soldier in charge asked for instructions, and then drove the steel drill into the ground less than 50 meters away from the body armor and fixed the steel crossbow.

After the steel crossbow was fixed, the two senior wrestlers rotated the winches on both sides, and the finger-thick wire bowstring was gradually pulled apart, and the originally loose bow blades turned into a full moon little by little.

With a "click", the bowstring pulled into place and stuck on the fixed trigger, and immediately after, a soldier next to him put a huge arrow the thickness of an arm, more than two meters long, into the slot on the steel crossbow.

The steel arrow shaft is bright silver, the surface is smooth, and it looks straight and traceless at a glance, showing the superb casting process of Black Rock City now, and there are three fixed tail fins distributed in the tail part of the arrow, the tail wing is not large, but the size of the three tail wings is symmetrical, and the distribution angle is almost invisible to the naked eye, only the riveted connection between the tail wing and the arrow shaft can see some flaws, but even so, if those forging masters see this long arrow, they are estimated to be shocked and drop their jaws. What's more, the color was clearly different from the shaft of the arrow, the arrow faintly glowing with indigo irregular moire, but at a glance, the eyes seemed to be stung by the hardness and sharpness of the arrow.

Obviously, the arrows of this steel crossbow have also been improved by the Institute, and the fixed tail wing that I didn't dare to use before, because the error of manual manufacturing is too large and easy to have problems, but now I dare to use it, which means that the accuracy problem has been overcome, although the position of the arrow is only a color change, but the real image will definitely not be so simple, everything depends on the effect after the test.

"It seems that you seem to have a lot of confidence in this steel crossbow," Lu Ya asked with a smile when he noticed the old man with a smug face.

"If the target is that strange set of clothes, I think it should be fine" The old man was obviously very confident in his research results, too, he had personally tested the power of this new steel crossbow in the research institute, and the special steel body armor that Lu Ya had summoned before, even AK47 could block it, but under the shot of this steel crossbow, it was shot through by an arrow without hindrance, and finally passed through the second layer and got stuck in the middle.

You must know that it is the body armor summoned by Ruya, and the steel of that kind of body armor is not the kind of thing they can also practice now, it is a powerful protective gear that can block the attack of Rock Lux, and it is still hated under the steel crossbow, so the iron old man has reason to believe that the strange costume hanging opposite will be worn by the steel crossbow.

"Unless that set of clothes is made of steel, even if it is ten sets, it will still not be an arrow from the main steel crossbow," the more the old man thought about it, the more confident he became.

"Oh?" Lu Ya was noncommittal about the iron old man's confidence, he was not thinking about whether the blast suit could withstand the fire of the steel crossbow, but whether the person wearing the blast suit could withstand the impact of the steel crossbow

Just when Lu Ya was thinking wildly, the soldier who received the order suddenly stepped on the trigger of the steel crossbow, "Weng~~~" The bowstring shook the air and resonated. The heads of the soldiers who were struggling with the steel crossbow were buzzing with resonance.

"Search~" A silver light as fast as lightning disappeared from the steel crossbow, and the next moment the sound of "bang" and "bang-la-la~" came from the opposite side, only to see that the cement low wall where the explosion-proof suit was hung just now collapsed instantly, and a burst of smoke rose from the scene.

"Wow~" The audience was in an uproar, and the soldiers all grew their mouths when they looked at the results caused by the steel crossbow. The soldiers in charge of shooting were even more dumbfounded, it was a cement wall, a cement wall twenty or thirty centimeters thick, it was the hardest thing they had ever seen except steel, and it was exploded with an arrow, so it was shot at themselves...
