Doomsday Bunker Upgrade

Laying the blade flat, he only used one finger to support the part of the blade close to the blade. He wanted to feel the center of gravity of the blade.

Feeling that the blade was already balanced, Chen Xin let go of the hand holding the handle of the blade. Under the action of gravity, the blade stood up on Chen Xin's finger with the back of the blade.

This is a feature of the samurai sword. If the casting is good, when the finger is placed at the center of gravity of the blade, the blade will stand up by itself with the back of the blade under the action of gravity, and it can be supported by one finger.

Seeing the black knife standing firmly on his finger, Chen Xin showed a satisfied smile, hooked his finger, and rotated the blade to take advantage of the situation to hold the handle.

Holding the knife and swiping lightly, Chen Xin could not even feel the weight of the blade, as if he was holding a feather.

But in addition to being light, this knife does not give the knife holder a feeling of lightness. When swinging the knife, he can still feel the process of power being transmitted from the handle to the tip of the knife.

Chen Xin was very satisfied with the change in his favorite knife, especially when he made a slashing action with this knife, and the blade made no sound at all.

"It's really a good knife, but the knife is still not concealed by a gun." Although Chen Xin had already fallen in love with his new favorite knife, he still put the knife back in the weapon cabinet after rubbing and playing with it.

His purpose of upgrading the weapon cabinet is not to upgrade these weapons, but to gain the ability to make firearms.

Pulling out the chair, he sat down in front of the extra workbench next to the weapon cabinet. Chen Xin briefly checked the tools on the table. Some he knew, but some he had never seen.

After picking up a few tools at random, and putting them back in place, Chen Xin found the firearm blueprints obtained after the upgrade of the weapon cabinet from the drawer of the workbench.

"7.62mm Double Action Trigger Semi-Auto Pistol Drawing"

"Parts needed: barrel, slide, recoil spring, trigger, hammer, safety, handle, magazine"

"Parts can be machined with tool benches or completed with survival points"

On the drawing is a pistol that looks familiar, somewhat similar to the M1911, but somewhat different.

However, Chen Xin is not a pistol enthusiast, and he doesn't have much research on it. What he cares about is how to make a gun, not what kind of pistol this is.

By reading the drawings and consulting the instructions provided by the system, Chen Xin finally knew how to use the tool table in front of him to make a pistol.

First of all, Chen Xin must have raw materials. If there are no or unqualified raw materials, you can spend survival points to supplement or improve the quality.

The second is to process according to the size of the drawing. The tools on the tool table are very complete, which can fully meet the needs of machining parts.

It's just that this is a bit of a test of Chen Xin's craftsmanship. If the machining accuracy is not enough, there is obviously a problem with the pistol made.

Of course this can also cost Survival Points to qualify an otherwise unqualified part.

But if the craftsmanship is not enough, and if you really want to save trouble, you can directly spend the survival points to manufacture the parts, but doing so will be a little more expensive than processing it yourself.

As for the assembly of parts, this cannot be replaced by survival points. The system only provides a 3D dynamic assembly diagram, and Chen Xin needs to do the assembly himself.

Knowing this, Chen Xin immediately wanted to make a pistol.

In terms of raw materials, because there is still steel left in the previous exchange, Chen Xin only needs to spend 2 Survival Points to improve the quality of the steel.

As for processing by himself, Chen Xin gave up the idea after hesitating for a while, but chose to spend another 3 Survival Points to let the system help complete the processing.

Looking at the neatly arranged parts on the workbench, Chen Xin suppressed his excitement and called up the assembly diagram provided by the system. After reading it twice, he made sure that he remembered the steps clearly. Assembly started.

Carefully assemble each part according to the system's instructions. Chen Xin's movements are quite slow. Compared with those on TV who can quickly assemble firearms while blindfolded, Chen Xin is obviously a layman.

But even so, he stumbled and assembled the gun.

Inserting the clip, Chen Xin pulled the slide and held the pistol he assembled by himself. Chen Xin made a self-assured aiming posture.

"Bang!" Chen Xin put the pistol back on the workbench with a naive mouth to simulate a gunshot.

For Chen Xin, a gun is a familiar yet unfamiliar thing.

Speaking of familiarity, what boy didn't play with guns when he was a child? Although it's not a real gun.

Unfamiliar, thanks to the Yan Kingdom's comprehensive gun ban policy, it is very rare for ordinary people to touch a gun or even see a gun in life.

Of course, even if Chen Xin has never seen a gun, he knows that the gun he assembled is useless now except to take it out to scare people.

Because it also lacks an important component, which is the bullet.

The power of a gun is actually largely determined by the bullet, not the firearm itself.

The firearm itself is just a platform for launching. Although it has a certain influence on the power of the bullet, the advantages and disadvantages of the firearm itself are more affecting the accuracy of the shooting than the power.

Most shooting games actually ignore this point subconsciously, which leads many people to think that as long as the gun has bullets, it can kill enough damage. The better the gun, the more powerful it is, but in fact it is not the case.

Chen Xin's pistol uses a 7.62mm caliber bullet, and the magazine can hold 12 rounds of bullets.

This is an international bullet type, and many countries in the world use this caliber bullet, not only for pistols, but also for machine guns.

Of course, pistol bullets and machine gun bullets are still different in length. Generally, the length of pistol bullets is 17mm, which means that the standard specification of 7.62mm pistol bullets should be 7.62×17mm.

Since the workbench has the function of making firearms, bullets, as an important part of firearms, naturally will not be less.

It's just that Chen Xin, who has no gunpowder, wants to make bullets, and still needs to spend 1 survival point to replenish materials.

Fortunately, making bullets is easier than making gun parts, especially when there is a machine, Chen Xin only spent some time to build a box of bullets.

Filling the bullets into the magazine one by one, and inserting it into the handle of the gun after filling, Chen Xin pulled the sleeve again, but this time a bullet had been pushed into the barrel of the gun.

Chen Xin, who was afraid of fire, closed the trigger safety, pulled out the magazine again and pressed a bullet in, then inserted the magazine back, touched the pistol, and felt a great sense of peace of mind.
