In the cabin, there are many strange parts on the wooden table in primary colors, which are made of wood, red copper, and some metal products that cannot be seen to be of good workmanship.

These things were all unloaded by Chen Zheng from alien firearms.

The first thing Chen Zheng studied was the gun he was initially interested in, the one held by the one-eyed dragon.

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

The propellant of this gun is interesting, it is pressed into a candle-thick column, and two such pillars are contained in the handle of the gun. At the top of the column, there is a very fine mechanical cutting device, which has a high cutting accuracy, and the visual inspection can reach about one-tenth of a millimeter.

The performance of this propellant is very strong, and in tests, it fired a projectile equivalent to the weight of a 7.62 NATO rifle bullet to achieve similar power with only a small powder column two sheets of paper thick.

Compared with the advancement of the medicine column, the projectile of this gun is very simple, just an iron rod the thickness of a pencil. Depending on the pattern, the cutting device inside the gun will cut the rod into different lengths to control the weight of the projectile, and then add different amounts of propellant and ignite it.

The projectiles and medicine pillars did not help Chen Zheng's situation, and this gun was only equivalent to a sniper rifle at its maximum power, and it was possible to penetrate brick walls and thin iron sheets, but for Roshan's armor, this thing was no different from a burning stick.

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

The first is the cutting device. It's small, and it looks like a normal ring, except that the gemstone should be set in a closed metal block the size of a thumb nail.

When the metal block is energized, a film of light appears between the rings, which exists for less than a tenth of a second and then disappears again. The nature of this light film is very similar to Chen Zheng's lightsaber, which can easily cut off metal rods, but its essence is slightly different from that of lightsaber, but Chen Zheng can't say what the difference is.

The thermoelectric conversion device is even better, it is a cylindrical space inside, where the column slice and the projectile will be filled, when the column slice is ignited, the expanded gas will push the projectile out of the chamber, and the heat from the gas will be absorbed by the thermoelectric conversion device into electricity.

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

The last thing is the battery, although I don't know what kind of black technology is contained in the black metal shell, but it must be true that it has a very sufficient power.

In addition to the above three black technology parts, the rest of the gun is not too high-tech, even the gun computer is just a simple chip, all the parameters are preset, so this thing is not high-tech even on the earth, and its complexity is similar to that of an electronic watch that a child plays with.

This gun is very simple in structure, as long as there are the first and second black technology parts, and replace them with ordinary batteries, even the handicraft workshops on the earth can make it.

However, the ease of manufacture and technical simplicity do not mean that the gun is low-tech, on the contrary, it just shows that it is very high-tech and the design concept is very advanced, far beyond the current level of the earth.

The design of the whole gun reveals a single idea: simplicity – simplicity in every sense of the word.

Simple logistics, simple use, simple maintenance and repair...... In particular, the maintainability is so high that almost all parts are modular and replaceable, and even some non-essential parts are discarded.

It can be said that as long as this gun has a barrel, a medicine column, and a three-piece set of black technology, even if all the other parts are broken, as long as a wooden board is found to fix them, this gun can still play a role!

In urban warfare, a soldier who has run out of ammunition can even insert a steel bar directly into it, and as long as the medicine column is not used up, he can continue to fight.

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

In fact, his guess was correct, the name of this simple and easy-to-make firearm is no longer verifiable, but its nickname in the Black Prison is famous: "cannon fodder gun".

Simple and reliable, the cannon fodder gun is suitable for mass production, and is the most reliable companion for those who have just arrived in the Black Prison, and it is also the easiest weapon to obtain.

But this Chen Zheng has nothing to do with it, for the cannon fodder gun, Chen Zheng is only interested in the black technology three-piece set.

The cutting device Chen Zheng can't use it for the time being, but its importance far exceeds the latter two, maybe that light film contains a lightsaber...... The secret of Zero Sword may not be known.

The latter two black technologies directly solved Chen Zheng's urgent need, and after getting this battery, Chen Zheng immediately installed it on the electromagnetic gun model, so that although there is no capacitor, at least it can be used.

However, when Chen Zhengxing rushed to shoot a shot, the word "can be used" was marked with double quotation marks.

When the two copper rails of the electromagnetic cannon were energized, Chen Zheng pressed the switch of the crossbow machine, and a copper pillar was directly ejected by the crossbow machine, and one got into the copper rails, and with a dazzling electric light, countless sparks sprayed forward! It's like a scorching firework......

"Poof."

Electric sparks and scorching copper shavings blackened the wooden plank that was a target two meters away, but the copper pillar that was a projectile fell on the snow a meter away with a "click".

"Uh......"

It turns out that the absence of capacitors is a "magic bullet" of fireworks.

But in this wilderness, where can Chen Zheng go to find a high-voltage capacitor!? In other words, what if Chen Zheng bought a high-voltage capacitor online? It's just an increase in the range of the copper pillar from 1 meter to 5 meters.

With the existing conditions, it would be a fool's dream to use an electromagnetic cannon to penetrate Roshan's armor.

A depressed Chen Zheng returned to the wooden house with his toy.

The way to increase power lies in front of Chen Zheng: increase the current and voltage.

Simple, isn't it? A few ultra-high voltage supercapacitors plus a power plant are sufficient.

No, it's not the right way.

Chen Zheng shook his head, drove away the more and more complex technical solutions in his mind, walked to the table and picked up the parts of the cannon fodder gun and looked at it, and a thought suddenly popped up in his mind.

Why don't you make it easier?
