Liang Jian: I Have a Technology Upgrade System

Among the three guerrilla artifacts, the rocket launcher can be given priority. You can refer to the Iron Fist rocket. It is really not difficult to make. And this is direct fire that can threaten bunkers and armored vehicles. In addition, for direct firepower, the barrels of low-bore pressure guns such as the 60-force and 82-force can be directly melted and processed with steel rails to thicken the wall thickness. The shells can be cast directly from iron, and the propellant can be made into black powder. Although the range will be shorter, the processing is simple and the quantity is guaranteed. For guns, I suggest you consider a breech-loading rifle with paper shell bullets and black powder as the propellant. This kind of gun can be mass-produced with simple technology and low material requirements, and can be scaled up quickly. In the early stage, it is better to hold one gun than a sword or a spear. In the mid-term, it can be replaced when the military industry develops. The replaced gun can also be used for training by new recruits. The low cost of bullets can give new recruits more points to improve their marksmanship. These firearms have low requirements for materials, manual machines, and training. It is not difficult to copy them. It will soon be possible to set up a military factory for each base area. By the way, there are also mines. Although the quality of the iron produced by the blast furnace is not good, it can be used to make these except for gun barrels and barrels. The shells and mine shells can be cast directly. Don't count on electricity as the power source in the early stage. Learn about the pot machine.

Before it gets colder, give me the ending of Yan Shuangying to feel refreshed

Author, don't tell me that the protagonist died of illness in the end?

Five-axis five-linkage, anti-war, there is this, it is not CNC, can it be used?

You are Shuangwen, why are you updating so slowly?

It feels a bit fast. Not long after the reorganization, it changed to guerrilla warfare and positional warfare.

Why do semi-automatics still use Japanese full-power bullets? Why not shorten the shell and make it a mid-power bullet?

At the beginning, you can get some heartless cannons, such simple ones as bullet mines and ordnance shovels.

Do I need to grind the shells thinner when reloading bullets?

After looking at the catalog, the updates are unstable and I feel like it's G!

Fast updates

Fire coverage, vitality coverage, vitality coverage!

By the way, why do machine tools have to use electricity? Can't the machine move without a motor?

That's right. After the smokeless gunpowder is finished, isn't it time to reach 56 and a half?
