Four hours later, the crow returned to the printing room.

'Click~' He threw a set of silver-black exoskeleton armor and a sturdy man tied up in front of Zhang Yuan.

"Oh, you want a sample."

The Aum man who was thrown in was still clear-headed, and as soon as he came in, he shouted at Zhang Yuan: "Wanted! Knave! You will not die well! When the Great Lord returns, you will all die!" ”

Zhang Yuan's heart moved when he heard this, and asked, "The big lord you are talking about is Han Sande, isn't he in Kansas now?" ”

"Yes, he's not in Kansas right now, otherwise there's no room for you rats to run rampant!" The captive shouted viciously.

The black crow on the side smiled: "In fact, Han Sande is now fighting against the Dark Shura people in the Behemoth Star Domain, as the supreme powerhouse of the upper stage of the apocalypse, he is the commander of the second legion of the planet Aum." ”

Han Sande is not in Kansas, so in this case, the so-called trial in Dallas is just a wild word, and if Han Sande is not there, then their situation should be absolutely safe.

Zhang Yuan just breathed a sigh of relief in his heart, but the black crow spoke again: "However, Han Sande and Kansas still maintain very close communication, and what happened here, Han Sande will know in 2 days at most." With Han Sande's character, once the situation in Kansas deteriorates, he will definitely rush back in person. ”

The captives also sneered: "Tremble, you rats hiding in the gutter!" ”

Of course Zhang Yuan will not be frightened, he originally thought that Han Sande was on the Kansas Star, and he didn't build weapons yet, but now Han Sande is not there, even if he may rush back at any time, but compared with before, the situation is not bad.

Ignoring the captive's angry scolding, he went to inspect the exoskeleton armor first.

Tsai carefully looked at this battle armor, Zhang Yuan already knew the performance of the battle armor, this is the 'liquid gold bionic skeletal muscle enhancement battle armor' equipped by the low-level warriors of the Aum Empire, which can increase the strength of the human body by 3 times, increase the speed limit by 2 times, can resist the attack of the sparrow laser gun, and there are various combat auxiliary equipment on it.

For unarmed civilians, a warrior equipped with an exoskeleton armor is indeed a super soldier.

Zhang Yuan walked up to the captive again, reached out and carefully pinched the muscles on his body, and soon, he had a general understanding of the physical fitness of this warrior.

In terms of muscle condition, this captive has been trained quite systematically, and its strength is far greater than that of hungry miners, roughly reaching the level of the ordinary middle section, and if it is fought head-to-head, it is estimated that a dozen miners can be killed by one person.

With such a warrior, combined with an exoskeleton armor, it is no wonder that the miners have to pay more than 30 lives to fight him.

So, what weapon should he use against these super soldiers?

Zhang Yuan pondered, the black crow and Lu Meng on the side were silent, and the captives on the ground kept scolding angrily, and after scolding a few words, the black crow walked up and kicked him in the neck, kicking him unconscious.

Ten minutes later, Zhang Yuan already had a rough plan in his heart, he took out a pen and paper, quickly wrote and drew 'brush, brush, brush', and began to design a new weapon.

This design process only took more than 20 minutes, and then Zhang Yuan emptied a thunderbolt printer and began to re-enter the parameters, and a few minutes later, he signaled to Lu Meng on the side, and Lu Meng immediately added printing aluminum to the printer.

Only then did the black crow on the side speak: "Mr. Zhang, the new weapon still uses this most basic aluminum alloy?" ”

Zhang Yuan explained: "Thunderbolt is a nanoprinter, and the minimum printing scale is 3 nanometers, at this scale, as long as the design is reasonable, the same material can show completely opposite physical properties. ”

"Oh." The crow nodded half-incomprehensibly.

The printer 'zizi' thought, one has a part that is constantly molding, and after the molding, Zhang Yuan directly takes it out and assembles it.

It can be seen that the parts printed by the printer are very simple, and the parts come out quickly, with an average of one every 5 seconds. Zhang Yuan's assembly speed is also fast, the peculiar thing is that each part is tightly fitted, and the 'click' sound when the parts collide when the assembly is smooth and coherent, which makes people feel very refreshing in their ears.

About 10 minutes later, a gun about 35 centimeters long, slightly larger in size than a Sparrow laser gun, with a large-caliber firing barrel of more than 2 centimeters, was baked.

The bullet fired by this thing is very strange, it is a smooth ball about 2 centimeters in diameter, and the surface of the ball is very smooth and shiny, just like a smooth silver bead that has been specially polished.

Stuffing the bullet into the barrel, Zhang Yuan stepped back a little and said to the black crow: "Put this exoskeleton armor on this guy, and then get him into the passage over there, and wake him up." ”

"Just this weapon? Will it work? The crow hesitated.

Zhang Yuan looked at him coldly: "Do you want to design weapons?" ”

The crow was speechless, he heard that the mechanical designers were proud, he didn't believe it before, but now he believes it.

He honestly did what Zhang Yuan said. He was afraid that the new weapon would malfunction, so he was not very relieved, so he deliberately put this soldier farther away.

When he had done this, he gave the captive an injection, and the captive's breath suddenly became short, and he was about to wake up, and the crow immediately ran to the side, staring at the captive with all his heart, for fear that something would happen, that it was a trivial matter for the printer to be broken, and that it would be troublesome if the two weapon makers were injured.

Zhang Yuan held the silver-white barrel in his hand, standing at the entrance of the passage and waiting patiently.

The passage in front of him was only 3 meters high and 5 meters wide, which was not particularly narrow, but it still greatly limited the space for these exoskeleton warriors to hide.

About 2 minutes later, the super soldier on the ground woke up, he got up dimly, looked down at his body, and found that the exoskeleton armor was actually wearing on his body, he quickly moved his arm, and found that the armor was still useful.

'Zi~', he immediately jumped up from the ground, and then he saw Zhang Yuan, Black Crow and Lu Meng at the entrance of the passage.

With the exoskeleton armor on his body, his confidence in his heart soared: "Hehe, three people, do you think you can stop me?" Stupidity! ”

He laughed out loud and rushed towards Zhang Yuan quickly, he could see that as long as he mastered this person and took him hostage, he could escape from this hellish place.

After putting on the exoskeleton, the explosiveness and speed of this warrior have been greatly improved, and the peak speed of such a sprint has exceeded 24 meters per second, and the sprint momentum is quite violent.

Zhang Yuan stood motionless, and when the distance between the warrior and him reached 50 meters, he pulled the trigger.

"Poof~" There was a soft sound, and the silver bullet in the barrel flew out, and halfway through the flight, it unfolded into a large silver net.

This net is round, about 3 meters in diameter, the net rope is very thin, like a hair, after this net appeared, almost the entire passage was spread, people can not hide.

The next moment, the exoskeleton warrior plunged headlong into the net, and the whole person was instantly wrapped in a ball of silver nets, and then, his whole person fell out like a dumpling.

"Bang~~" Eventually, the exoskeleton warrior slammed into the stone wall, then rolled to the ground, and after landing, he kept struggling, trying to break out of the net.

But this net is very tight, although the net rope is thin, but it is very tough, and more importantly, it wraps his whole hands and feet, and he can't exert his strength at all.

As a result, the more he struggled, the tighter the net became, and at last the warrior fell to the ground panting, motionless.

The crow was dumbfounded, he walked in front of the warrior and squatted down to look at the silver net carefully, and then reached out to pull the net rope, and pulled it a little harder, but it was not broken, if you pull it harder, this thin net rope will have to be tightened into the flesh.

He looked back at Zhang Yuan: "This thing is also made of aluminum alloy?" ”

Zhang Yuan nodded: "This is an aluminum alloy nanotube with a Caphora structure, which is tough, sharp, and resistant to high temperatures. This gun has a range of 60 meters, no recoil, and is basically not difficult to operate, as long as there are enough bullets, it can be fired continuously. ”

As he spoke, Zhang Yuan stuffed 4 silver balls into the barrel of the gun, and then pulled the trigger one after another, and with four sounds, four silver nets appeared in the air and rushed into the distance.

The narrow environment of the mine limits the maneuver and dodge of these super soldiers, and with this net gun, these fighters can easily hit and restrain their movements. The advantage of the Mine Protector is that they are numerous, and their attacks are intensive, and once these super soldiers lose their mobility, it is basically over.

The crow's eyes are shining, the operation is simple, the cost is low, and the effect is amazing, this thing is not dazzling high-tech, but it is the most perfect weapon for miners who have not undergone much training and have no culture!

He was now almost certain that if he threw this net gun into battle, combined with the power of the focused laser gun, it would be the end of this super soldier.

He excitedly asked: "Very good, very good, how much can this weapon be produced in a day?" ”

"This thing has a simple structure, and one printer can print 1,500 pieces a day."

"Haha, okay, let's get 1500 first. You can rest assured, as long as you work hard, Lord Dallas will never treat you badly. ”

A trace of 'resentment' flashed on Zhang Yuan's face, and without saying a word, he turned around and started printing the net gun. Lu Meng, who was on the side, sneered: "Don't pretend, it sounds disgusting, you just want to coerce us to build weapons for you for free!" ”

The crow shrugged his shoulders, "My friend, don't think so, it's not good for you. ”

He wasn't surprised by the two men's reactions, and anyone would be upset if they were coerced, but it didn't matter, as long as they could continue to help them produce weapons.

After that, Black Crow waited in the printing room for more than 2 hours, and when the first batch of 200 net guns came out, he immediately took the net guns away.

Zhang Yuan and Lu Meng were relieved that they were not monitored, and after the two of them set the printing parameters as before, they continued to train and rest, and always maintained a perfect combat state.

As the days passed, the miners had achieved good results from the energy sensors, and they had advanced the battle line a full 10 kilometers, not far from the center of Ghost City.

Three days later, when Zhang Yuan was producing weapons, his ears suddenly moved, and he heard a strange voice coming from the passage.

The voice was very soft, but it couldn't hide it from Zhang Yuan's ears, and after listening carefully for a while, he said to Lu Meng, who was already alert on the side: "Be careful, there are infiltrators." ”
