Compared with the birth of the Nafeng smoke crystal cannon, the appearance of another good news made Xu Yuan a little excited.

That's it, drones!

And it's not the kind of drone that Xu Yuan imagined that can only take pictures, the design of the drone that turned out of the box is the kind of shape that can poke out the shooting hole at the bottom.

Although the design of the drone is a bit complicated, after the improvement of the researchers at the base, a simple self-targeting and shooting drone appeared.

Of course, although it is simple, the cost of each unit is about 100,000 yuan crystals.

But as soon as he thought that there would be a scene in the future, where the entire security zone would be surrounded by drones, and as soon as he gave an order, those drones would be ordered to start shooting, Xu Yuan instantly felt his heart flutter and began to jump.

What about 100,000? Just make it for me!

After two days of reconnaissance, the attack was scheduled for seven days later, and the survivors in the base were back busy.

Although it sounds a bit fucked up to go to war in the heavy snow, as long as it is Xu Yuan's decision. They will do it without hesitation!

Because Xu Yuan has "meat" to eat, under the absolute interest, what is the blizzard?

The newly assembled military factory worked overtime, and workers welded the peak smoke cannons to the modified trucks, as instructed by the researchers.

The training ground outside was also lively, and the soldiers wearing cold-proof suits were nervously carrying out pre-war training under the leadership of Zhao Wenlong.

However, it seemed that everyone was preparing very seriously, but Xu Yuan didn't feel any worries about this attack, just a few hundred radiant people, even if they had guns in their hands, they were just some ordinary machine guns.

On the fish bone side, there is not only the peak smoke crystal cannon to provide fire support, but also the new weapons that have been researched!

That's right, Xu Yuan is now visiting the new weapon that researchers have developed for him.

It may be that on the source star, the scientists who study the aerospace industry do not have any role in the safety zone, but for Xu Yuan, their importance is simply too great!

So, despite the dissuasion of everyone, Xu Yuan built a laboratory in the rear alone, and took out a lot of funds to give them research.

Although space technology may not be of much use to the safe zone at this stage, rockets are not only used to shoot into the sky!

Shoot at the ground, that's ground-to-ground**!

How strong is it? Just look at the top reserves of various countries on the planet.

Of course, the purpose of Xu Yuan's coming this time is not for **, even if this thing is given to him, he won't need it now, the reason is naturally because there is no launcher.

Opened the door of the laboratory, Xu Yuan stepped into the door quickly, and then quickly closed the door behind him, stood at the door and shook the snow on his body, and then he walked towards the house.

"Lao Wang? What are you doing? Xu Yuan curiously walked towards Wang Haisen, the head of the laboratory.

All kinds of mechanical parts were randomly stacked in the corner of the room, and Xu Yuan didn't know what these things were for, he only knew one thing, these things were very expensive.

There are even some parts that cannot be bought by money at all, and can only be found through shelters or digging underground.

"It's okay, fix a small thing," At this moment, Wang Haisen was disassembling a big iron box with a change cone, looking at the dense wires in the iron box, Xu Yuan suddenly felt a headache and dazzle, even if this thing is for himself, it is estimated that he can't figure it out.

After looking at it for a long time, Xu Yuan still didn't see anything, so he asked out loud: "Has the task I arranged for you before been completed?" ”

"It's done," Wang Haisen returned without looking back: "You go and get it yourself first, I can't let go of this hand, otherwise I will give up all my efforts, and the thing is in the corner over there,"

After shaking his head a little helplessly, Xu Yuan walked to the set of equipment placed in the corner.

"B-3 mechanical exoskeleton armor," a small line of small letters appeared on the side of the iron shell in front of him.

Looking at the B of the former subordinate, Xu Yuan secretly gave Wang Haisen a thumbs up, although this guy doesn't understand any human feelings, he can make a B model machine is already very good.

Picked up the various parts on the ground, Xu Yuan studied for a long time and didn't come up with any clues, so the others had to reflexively pick up the manual, and then carefully studied and compared.

After most of the day, according to the instructions on the manual, Xu Yuan finally put on the broken parts.

The light unknown metal fits the sides of the limbs, and the spine is covered by overlapping metal sheets, each part of which is tightly attached to the body, and there is no sense of lag when moving, Xu Yuan nodded with satisfaction.

On the other side, Wang Haisen saw that his big boss had already dressed his masterpiece, so he got up and walked over, and at the same time, under Xu Yuan's curious gaze, he pressed a button located on the back of his head.

A faint sound of electricity slipped by, and Xu Yuan only felt a slight numbness in the back of his neck. The next moment, a shocked expression appeared on his face.

It's a wonderful feeling, as if these metal bars are all part of your body, and it's no longer the bones in the flesh that drive your body to move, but the metal exoskeleton attached to the outside of your body!

At this moment, Xu Yuan was no longer calm as before, and his face showed a heavy surprise!

At this time, Wang Haisen took a few steps back, beckoned to Xu Yuan, and said, "Come, you can try to take two steps forward first, and then move your limbs to see if there is anything uncomfortable." ”

Hearing this, Xu Yuan walked forward very easily as if he was walking on weekdays, and if he put on a wide coat, he would not be able to see that he was carrying so many parts on his body.

After walking back and forth several times, Xu Yuan nodded involuntarily: "It feels great, as if this thing has become a part of my body, and there is no discomfort at all." ”

"Here's this for you," Wang Haisen looked left and right, then grabbed an iron ball from the ground and handed it to Xu Yuan to signal him to pinch it hard.

"Squeak, squeak," a shrill noise suddenly sounded, and in Xu Yuan's shocked expression, the solid ball was actually directly flattened by him by relying on the power of the outer armor of the mechanical skeleton!

At this moment, Xu Yuan was shocked in his heart, just with a few metal shelves, people could gain so much power.

So if every soldier were given one piece, how much would the combat effectiveness of the security zone increase?

At least double!!
