In the wooden house, there are many strange parts placed on the original wooden table, including wood, red copper, and some metal products that cannot be seen with excellent processing.

These things were all taken off by Chen Zheng from alien guns.

The first thing Chen Zheng studied was the gun he was interested in at first, the one-eyed dragon holding.

Although this gun is very advanced in a sense, its principle is to drive the projectile through chemical energy storage and gas expansion. In essence, it still belongs to the category of "gunpowder" weapons.

The launching medicine of this gun is very interesting. It is pressed into a candle-sized medicine column, and two such medicine columns are installed in the handle of the gun. There is a very fine mechanical cutting device at the top of the medicine column, and its cutting accuracy is very high, and it is visually estimated that it can reach about one tenth of a millimeter.

This launcher has very powerful performance. In the test, it was fired with a pellet of the same weight as 7.62 NATO rifle bullets. It only takes two small gunpowder columns of paper thickness to achieve similar power.

Compared with the advanced medicine column, the projectiles of this gun are very simple, just iron rods as thick as pencils. Depending on different modes, the cutting device inside the gun will cut the iron rod into different lengths to control the weight of the projectile, and then add different amounts of launching medicine and ignite it.

The projectiles and medicine pillars were of little help to Chen Zheng's situation. The maximum power of this gun was just equivalent to a sniper rifle. It was possible to penetrate brick walls and thin iron sheets, but for the armor in Roushan, this thing was no different from a fire stick.

However, this gun gave Chen Zheng a great surprise in other aspects. After completely disassembling the gun, he obtained three real black technology parts: one is a metal projectile cutter, one is a thermoelectric conversion device, and the last is a high-performance rechargeable battery.

First of all, the cutting device. It is very small and looks like an ordinary ring, but the gem should be inlaid with a closed metal block the size of a thumbnail.

When the metal block is powered up, a light film will appear between the finger rings, which will disappear again after less than one tenth of a second. The properties of this light film are very similar to Chen Zheng's lightsaber. It can easily cut the metal rod, but its essence is slightly different from that of the lightsaber. However, Chen Zheng can't tell where this difference lies now.

The thermoelectric conversion device is even more wonderful. It has a cylindrical space inside, where the medicine column slices and projectiles are concentrated here. When the medicine column slices are ignited, the expanded gas pushes the projectiles out of the gun chamber, and the heat brought by the gas is absorbed by the thermoelectric conversion device and becomes electricity.

On the one hand, this device solves the problem of heat dissipation when the shellless gun is continuously fired, and on the other hand, it also provides energy for gun-mounted computers, scopes, auxiliary devices and cutting devices.

The last one is naturally the battery. Although I don’t know what kind of black technology is contained in the black metal shell, there is definitely nothing wrong with its very sufficient power.

Apart from the above three black technologies, the rest of the gun has no high technological level. Even the gun-mounted computer is just a chip with simple functions. All parameters are preset, so this thing is not considered high-tech even on earth, and its complexity is similar to the electronic watch that children play with.

This gun is very simple in structure. As long as the first, second and two black technology parts are replaced by ordinary batteries, even the handicraft workshops on earth can be made.

However, the convenience of manufacturing and technical simplicity do not mean that the gun has low technological content. On the contrary, this just shows that it has high technological content and very advanced design concepts, far exceeding the current level of the earth.

The entire gun design reveals a concept: simplicity - simplicity in various senses.

Simple logistics, simple maintenance, simple usage, simple repairability... Especially with the high repairability, almost all parts are modular and replaceable, and even some non-essential parts can be simply replaced with other things.

It can even be said that as long as this gun has a three-piece set of barrels, medicine columns, and black technology, even if the other parts are broken, just find a wooden board to fix them, the gun can still work!

In urban warfare, soldiers who have exhausted ammunition can even directly use a steel bar to make ammunition and insert it. As long as the medicine column is not used up, they can continue to fight.

Chen Zheng suddenly felt that this gun must be a classic weapon that has been tested on the battlefield for a long time.

In fact, his guess is correct. The name of this simple and easy-to-made gun is no longer verified, but its nickname is very famous in Black Prison: "cannon fodder gun".

The cannon fodder gun that is simple and reliable, suitable for mass-made cannon fodder gun is the most reliable partner for those who have just arrived in the black prison and the easiest weapon to obtain.
