"Since you yourself are not willing to build a strong defense system, then I will help you build a defense system! The greatest enemy of mankind is mankind itself. It's always good to be a little more defensive!" Xiao Rui said to himself.

In the basement, there is another robot that is several times larger than Xiao Rui, and the robot at this time stands quietly on the workbench, and its appearance is also like Qian Yiduo.

Xiao Rui is only about 120 mm tall, with a slender figure, completely a miniature version of Yang Rui, wearing a pink knee-length dress, while the other three robots are nearly 150 mm tall, and their body size is three times burly!

As soon as Xiao Rui arrived, the robot also gave a military salute.

"Let's continue to work!Xiao Jiu, cover monitoring!" Xiao Rui gave an order to the three robots standing in a row, and then gave an order to Xiao Jiu, the supercomputer next to him.

"According to the old rules, Qian Erduo continued to make bullets, Qian Sanduo, and Qian Siduo continued to manufacture machine guns. Our task is very intense, comrades need to work hard!" Xiao Rui saw that Xiao Jiu, who controlled the entire villa monitoring system, showed the entire three-dimensional environment of the villa, and there was only one robot standing quietly on the workbench in the basement, and their scene did not appear, and then gave an order.

"Yes!" the three robots with the appearance of more money and one more began to act after giving a military salute again.

In the opposite direction and on both sides of the workbench, there are three rows of shelves, on which various raw materials are placed, in order to facilitate these small robots to take materials, Qian Yiduo deliberately designed this.

Before starting, the three burly robots were directly broken down into large and small robots, the relatively large robots were constantly carrying various metal materials that were cut into small pieces or simply powdered from the shelves, and the small robots were assembled into various mechanical processing equipment according to their tasks to process those materials.

Different from ordinary machining equipment, these robots are composed of equipment, if it needs to rotate, directly on the chest position appears a hole in the same hole as the material blank, the other robot is raised hand, when the material begins to rotate, the hand will fire a laser, quickly cut the material.

The scrap that falls is broken down by a smaller robot and processed from the molecular structure.

This is somewhat similar to the 3D printing process that is currently more popular on the market.

However, it is a variety of metals that are processed, and it is not necessary to melt the material before processing, but to decompose the material into the most basic molecular structure in various proportions according to the need, and then integrate other elements to form a new alloy material.

The bunch of robots responsible for making bullets were broken down into far more robots than the 33 that Qian Yiduo had seen, but more. Robots of all sizes, some are responsible for processing warheads, some are responsible for processing bullet shells, and even, on top of the warheads, there are a large number of nanorobots for further processing.

Unlike normal bullets, these bullets do not contain any chemical propellant at the point where the warhead is attached to the cartridge case, but are stuffed with various very small electronic parts.

Even, at the tail of the bullet, there is a small tail!

The sharp and slender warhead, which is even more different from ordinary bullets, is no longer a bullet at all, and some of them are like a reduced version of a missile, especially the tail fin, which makes this bullet look a little weird.

Regardless of any country, the main part of the bullet is composed of three parts: the warhead, the propellant, and the cartridge case, and the propellant contained in the cartridge case explodes instantly to produce a huge thrust, so that the warhead is ejected from the barrel at a high speed. The bullet casings were ejected directly inside the chamber, and it now appears that the bullets do not seem to be separated from the cartridge casings.

Compared to the number of nanobots, the bullet seems to be easy to process, but in fact it is very slow, not because of anything else, but the internal structure of the bullet is too complex, from the very beginning of the construction to the first bullet molding, it took nearly half an hour, but the speed is faster, basically five minutes to be able to make one.

After the first bullet was made, some of the robots went to the next power socket, and these robots assembled into coils that were almost the same as the bottom of the bullet, while the other robots carried the bullet, which was somewhat large for their size, in front of the coil, and then stood the bullet, and the current in the coil gradually flowed into the bullet.

The robot processing firearms next to it has a larger workload, but the processing speed is faster.

In less than half an hour, a silvery-white barrel about ten centimeters long and the thickness of a little finger had been formed, and then the trigger, sleeve, grip, etc., were gradually formed.

However, in the manufacture of robots, there are no major parts of firearms such as hammer springs, main springs, and firing pins, and instead there are a bunch of strangely shaped electronic parts.

"Hmm, it seems that there is still a lack of manufacturing materials for the display screen!" Xiao Rui looked at it from the side, almost all the parts in her database were already there, but she found that there seemed to be a lack of display screens and other related things.

Then, she jumped down from the workbench, stared at the display screen of the supercomputer Xiao Jiu on the side, which had almost no effect and was completely disguised, and looked at it with a frown, "Tear down a little on this?"

"No, if you know, you'll get angry!" Then, she shook her head, "By the way, there are not several TVs outside, and it can take a long time to dismantle any one!"

"No, you can't dismantle it, but if you do, you'll be discovered." Well, let's get inside and get a little bit of each material!" Xiao Rui finally patted his head and walked outside with an excited face.

Some open places in the villa are monitored, the sky outside has already been brightened, Qian Yiduo slept very soundly, Xiao Rui came out of the basement, and there was no movement in the whole villa.

The basement is the closest to the living room, especially the living room has a 70-inch curved LCD TV hanging on it, this thing has been lived in from Qian Yiduo, and it has basically not been turned on.

Xiao Rui walked to the front of the TV wall, the whole body began to decompose, into a large number of ant-like robots, climbed up along the TV wall, and drilled into some heat dissipation holes behind the TV, and soon, these ants each carried various materials behind their backs and drilled out of the TV, not reassembled into Xiao Rui, but like moving ants, lined up with various materials on their backs, and went straight to the basement.

None of this was recorded by the surveillance cameras installed in the living room.

It's not that they weren't recorded, but after these pictures were monitored and transmitted to the central control system, Xiao Jiu modified the pictures, deleting all the scenes of Xiao Rui and the mechanical ants, leaving other pictures, even if these pictures were erased, there would be no traces.

"Xiao Jiu, pay attention to Qian Yiduo's movements. After the robot ant team neatly placed all kinds of materials taken from the TV on the workbench, Xiao Rui gave an order to Xiao Jiu.

Construction continues.

An hour later, a second barrel appeared on the workbench, which was about the same size as the previous one, but twice as long as the previous one. At the same time, the third barrel is also halfway finished.

At present, the barrel of most countries in the world is machined, first casting the blank, and then using a deep hole drilling machine to drill the barrel, and then, the hole in the middle of the barrel after the completion of drilling is stuffed into the mandrel engraved with rifling, and then the forging machine is cold forging, in such a process, the blank material of the barrel is gradually elongated, and the internal rifling will also be preliminarily completed. After cold forging, the barrel has to be cut on the outside, then chrome-plated on the inside, straightened on the barrel, and finally finished on the inside of the barrel.

This barrel processing technology is much more advanced than the original processing technology. In the past, most of the steps were similar, but instead of stretching the barrel by cold forging, a sufficient length was cast at the time of the blank, then forging, deep hole drilling, and finally using a broaching machine to finish and rifle the inside of the barrel......

And these robots in front of me make gun barrels, which is not the same process at all, just like 3D printing technology, piling up various materials, and in the process of accumulation, all the rifling has flowed out.

On the workbench, the barrel is only half sided, as if a water pipe had been cut horizontally.

A large number of robots are continuing to pile up materials.

The whole manufacturing work, from the dawn of the morning, Qian Yiduo has been carried out in a tense and orderly manner, in this process, Qian Yiduo has not woken up, and even at noon, when Qian Yiduo was about to wake up, Xiao Rui climbed next to Qian Yiduo's head and released an electric current at him, so that he continued to fall into a deep sleep.

By about three o'clock in the afternoon, there was already a strangely shaped pistol, four rifles were completed, and the four rifles were not ordinary goods, and there seemed to be no problem on the outside, especially the barrel, which had nothing to do with the gun, but there was no handle and trigger in the back, but a pedestal!

Obviously, this is not a gun in the conventional sense.
