"Platoon Commander Zheng, their death is valuable, because they protected and protected the most important property of the People's Republic of China, the results of the 748 Project", the two engineering vehicles manufactured were also copied on one side, and although their speed was not as fast as the ACU, they could also replicate one in 10 seconds. In the eyes of the girl, there will soon be a toy car army on the ground, because in the eyes of ordinary people, this kind of car that is no more than a model in size, I don't know what the meaning is, although the appearance that can be made by spray paint out of thin air is indeed terrifying.

There are more than 10 engineering vehicles, and these engineering vehicles have begun to deploy rejection horses and missile towers around the perimeter, in fact, the structure of the missile tower is very simple, just a central axis plus a launch nest, and there are 7 missiles in the launch nest. Although it is a pocket version, the caliber of the missile has been reduced to 12.7 mm, like a machine gun bullet, but it is still powerful enough to kill most types of [BEAT], and because it is a pocket version, it is very light and can be mounted on a slope in a tree. The height of the bottom bracket is also adjustable. The staggered arrangement of missile towers constitutes the first line of defense, and after a certain number of missile towers, we began to manufacture [Kruger] type tanks, the reason for making this tank is that this tank is large enough, even the mini version is more than 30 centimeters high, more than half a meter long, and cheap, this vehicle originally had a twin 130mm electromagnetic turret, and I modified it and replaced it with an electromagnetic railgun with a maximum caliber of 280mm, so this car has a 28mm caliber even after miniaturization, Although it's still small, it's finally a cannon, and the caliber is sometimes justice. The difference between an electromagnetic railgun and an electromagnetic gun is that the railgun is two parallel rails as a firing track, and the caliber can be adjusted, while the caliber of the coil gun is nailed like a traditional gun, and the railgun is generally designed with a rectangular shell, which may have a fairing, but the muzzle velocity of the coil gun is fast and the firing range is long, and the initial velocity of the railgun is slow and suitable for projectile. Of course, this is relative to the speed and output power, and if fired at maximum power, they are still much faster than traditional artillery.

The Kruger is a type of engineering unit that builds large vehicles, not a depot. There are some units like the real yàn-level units, which we jokingly call the semi-real yàn-level. He consumes more resources than a normal unit, but with my current output of 3300 energy plus 15 mass, he can still handle this kind of construction task. When I was building these things, the surrounding [BEAT] was approaching this direction, and there were not too many of them, that is, more than 200 horses, most of them below the tank level. The power of these devices is enough. The benefit I received from the system is that the capacity of my portable mass warehouse and energy storage is 10,000 units, which is the highest capacity of the commander in the sweeping army, and the energy is good to say, the quality of 10,000 can bring me a lot of advantages, because I can accumulate quality in peacetime and use it at critical times.

"The 748 project has achieved several breakthroughs, 1-material breakthrough, which has achieved the smelting of basic substrates, and 2-production technology breakthrough, which is called 3D printing technology. It is to use the matrix raw materials to present the material through a technology similar to a printer to achieve rapid construction, 3-artificial intelligence, and these cars and weapons displayed in front of you are fully automatic AI control, automatic multiplication and evolution, and you can soon see the power of these toys. "I continued to explain to the girl next to me while building the Kruger, and at the same time ordered the engineering vehicle that had finished building the missile tower to build a second line of defense in the rear, ready to rely on the layers of defense to provide me with enough time to retreat with the girl.

The first to speak was the mini version of the [Kruger] tank, the 28mm rail shell fired by the mini version of the Kruger tank first fell into the middle of the tank stage in front of the protrusion, and the shock wave of the metallic hydrogen explosion swept across an area with the metal fragments, plowing a gap in the [BEAT] group, but the [BEAT] in the rear was quickly filled, and with the [Kruger] speech, the pre-arranged missile towers all thought about their respective targets and opened fire, at this time the power of the hive network was reflected, Each missile tower will attack a different enemy, and there will not be a situation where two missiles will attack one enemy. The rate of fire of the missile was fired in 3 seconds, and 7 spare rounds were fired, although the 12.7 mm caliber was a little smaller, but the flexibility of the missile was enhanced. The hit rate is 100%. When the first round of fire was overridden, there were only two or three kittens left in the [BEAT], and the [Kruger] tank ended later, and the whole battle ended in less than 10 seconds.

Whew~~ Breathe a sigh of relief, it seems that although the caliber has become smaller, it is still usable. After checking the state of the unit, the missile tower that had run out of ammunition was given an order to self-destruct and then the wreckage was recovered, and the mosquito legs were also meat"After [BEAT] landed in Kashgar in the 70s, some scholars in China believed that there is a fundamental difference between us and [BEAT] in terms of productivity, and this fundamental difference will lead to the defeat or even extinction of mankind. Although this kind of defeatist thinking cannot be openly discussed, but there are objective facts, so in 1975, under the personal instructions of Comrade Chairman Mao, the [BEAT] productivity countermeasures office, began secret preparations, this office does not consider morality and ethics, only thinking about how to defeat [BEAT] in the link of productivity, and finally on April 8, 1977, the project was formally established, this is the origin of the 748 project, and I am the final result of the 748 project. The next wave of [BEAT] is coming, so let's go to the next line of defense. ”

I held out my hand to the girl again, and was ready to take a punch, but this time it was smooth.

As the girl moved towards the second line of defense, there was a strange silence on the road: "Don't you have anything to ask?" "I broke the ice and took the initiative to talk.

"I don't know what to say, I can't understand any of these things, but is what you're saying true?" It must be all fake, so don't you need to say it? But I can't tell you that I'm from another world. I also think the previous story was too clumsy, so I'm going to make amends.

"Fake."

The girl was silent

"If the higher-ups had supported this plan, we wouldn't have had to let you kids be cannon fodder here. However, the rest of the part is true, although the plan was supported by Comrade Chairman Mao, but after the death of Comrade Chairman Mao, the plan was shelved, and the supporters of the plan decided in 1977 that the state would not support it in time to continue, so with the support of illegal means such as misappropriation of funds and dumping of materials, the project still achieved certain results. However, under the attack of [BEAT], the project team was also scattered, and everyone except me was eaten by [BEAT]. But I finally put together all the results a few minutes ago, and now I can proudly declare to the world that Project 748 has been a success. "It's still a lie, don't I dare to say that I came through it? Ay~~~~.

In the process of chatting, we have crossed the second line of defense, the second line of defense is stronger than a tunnel, when we arrived, nearly 100 defense devices have been densely built, in addition to the missile launch nest, there is also DM1 plasma point defense, and the engineering vehicle also began to clear the vegetation in the shooting range, and build a horse blocking [BEAT] activity space on the ground.

"So fast?" The girl exclaimed, "Can I touch it?" ”

"Of course, these things are just aluminum-iron alloys." This is another lie, this is the original unit, although the main component is an alloy material of iron, the material is degaussing and anti-corrosion process, and the performance is not comparable to any material on the earth now. The names of these alloys are simple, ranging from Material 01 to Material 228, a total of 228 materials make up the entire unit of UEF. These materials are basically made of iron or hydrogen, and are manufactured into materials with different characteristics through special processes and different formulation ratios.

As for iron-aluminum alloys, it's because I'm ready for the diffusion of technology. I'm going to spread this technology, UEF's original technology is too much higher than the human level, and the current human can't copy it at all, and I only have the rank of second lieutenant, and I can only control the original unit of zhì500. In fact, in order to prevent ACU rebellion, each race has added a unit restriction to ACU, which limits the number of units and also clears the possibility of ACU rebellion. Because of the unit restrictions, it is also called those dreams, with ACU, you can overturn the dreams of secondary school teenagers all over the world by yourself. Hey~~ I'm going to pick up the ACU's security system when I have time, and see if I can kill her, otherwise I'll have enough 500 units to fight with [BEAT].

When I get out of here, I'm ready to spread the basic 3D printing technology, and for 3D printing, the substrate is very important, and that kind of iron-aluminum alloy is the most suitable. In 3D printing, iron powder and aluminum powder and some trace element powder are used as the substrate, and when the laser is used in printing, they can be mixed into alloys through a special process, and different metal properties can be obtained by changing the formula to meet different needs. Iron and aluminum, the main materials, are extremely abundant on Earth, and I believe that this technology will definitely increase the logistical capacity of mankind. It can restore the productivity gap with [BEAT].

Girl, which engineering vehicle picked it up, and then looked over and over, the engineering vehicle was waving a mechanical arm in the girl's hand and trying to struggle out, and the countless counterattack requests on my ACU were ignored by me.

"Don't interfere with the work of these vehicles, [BEAT] is about to reach the second line of defense. Let's go, don't make your teammates wait. As he spoke, he quietly saved the engineering truck from the girl's hands, and after the engineering vehicle landed, he happily ran to his place to build something. This is the second line of defense that is the most important line of defense in my booking, because you can see the sea beyond a hill, and if you call the light level to strafe on the mountain, we can only hehe. So be sure to hold off the BEAT's army here for a while. Because the resistance of the whole island is over, and we are the only ones left, [BEAT] is moving towards here, and this is what my vibration sensor told me.

"Aren't you here commanding these units?" The girl asked suspiciously.

"They don't need to be fully automated! They will attempt to annihilate any BEATs that come near them until they are destroyed or the BEATs are wiped out. I said to the girl categorically, and took the girl's hand and walked towards the beach. We are not too far from the sea, only 3 kilometers in a straight line, but in the mountains, we still need to climb a hill to see the sea.
