Wasteland Survivalist: A Scientific Guide to Post-Apocalyptic Survival

When Gu Lang woke up the next day, he had finally regained his strength.

The medical waste disposal center we are currently in is a perfect sanctuary.

It was secluded enough and well-equipped, allowing him to get a rare, peaceful night's sleep.

The Geiger counter shows that the current ambient background radiation level is 5 microsieverts per hour.

This location is far from major cities and important military targets.

With an average altitude of 600 meters, it is less affected by nuclear war.

Gu Lang got up to use the toilet and, as usual, turned on the tap, only to be pleasantly surprised to find that there was water.

After some investigation, he discovered that there was no running water connection here.

Because the location was too remote, the construction team drilled several wells on the spot.

The well water is periodically pumped into the rooftop water tank using a water pump.

He tested the well water and found that the radiation level was as high as 150 microsieverts per hour.

It was clearly affected by radiation rain.

Fortunately, the water stored in the rooftop water tank was pumped in before the outbreak of nuclear war and was not affected.

Gu Lang quickly found a water pipe and filled the light truck's water tank with precious clean fresh water.

Seeing that the water pressure hadn't dropped, he went to the bathroom to take a shower.

They also unexpectedly discovered scissors, clippers, and razors.

After disinfecting the tools with alcohol, he took off his clothes.

I shaved my head and trimmed my eyebrows.

He also shaved off both his upper and lower beards.

Hair itself does not absorb or store radiation.

The problem is that it provides surface area to adhere to and retain radioactive dust.

If this dust is inhaled through the mouth and nose, it can cause internal radiation.

If you are in a safe shelter, just make sure to clean thoroughly.

There's really no need to shave your head for such a small risk.

But the "nomads" of Gulang obviously did not have this opportunity.

Reducing hair volume can significantly save time and water usage in daily cleaning.

After taking a nice shower, I hung up the washed dirty clothes to dry.

He went to the kitchen and saw that the cabinet doors were wide open.

The staff took all the food with them when they left, not even leaving the seasonings.

Only the stove and two gas cylinders remained in the kitchen.

One of the gas cylinders appeared to be a spare; the plastic seal was still intact, and it was clearly full.

Gu wasted a lot of effort and simply moved it onto a light truck.

Then he took vegetables, rice, and canned goods out of the car and cooked himself a meal.

After more than half a month, he finally got to eat a hot meal.

Gu Lang ate three bowls of rice with stir-fried cabbage with black bean bream and stewed beef brisket with potatoes.

After burping, he patted his belly and went to the duty room.

He placed the weapons he had seized yesterday on the table and began to examine them.

Gu Lang opened the cylinder of the Type 05 revolver, which contained four bullets and two empty cartridge cases. There were also six spare bullets on the holster.

Gu Lang took out the spent cartridge case and replenished the ammunition.

Although he wasn't entirely satisfied with the gun's power, it was still a standard-issue weapon.

Its reliability and concealment are quite good.

In contrast, while the two homemade guns were very powerful, their reliability was far worse.

It's basically a matchlock gun from several hundred years ago.

Like all muzzle-loading smoothbore guns, gunpowder needs to be loaded from the front of the barrel.

Use paper packets as soft packing to wrap the bullet.

Then use a long tamping rod to push it in and compact it.

The other end of the trigger is connected to a fuse that can burn slowly.

It appears to be hemp rope that has been soaked in potassium nitrate solution.

Pulling the trigger would ignite the tinder in the pot.

The flame ignites the propellant in the chamber through a ignition port on the side wall of the barrel.

The intense combustion of gunpowder generates high-pressure gas, which propels the projectile out of the barrel.

This gun not only has an extremely slow reload time, but it also cannot fire in bursts.

Furthermore, it is completely unusable in rainy and humid environments.

After studying it for a while, Gu Lang decided to completely redesign it.

He opened his phone and typed "Heaven punishes the traitors" into the search bar.

A blueprint for a homemade gun appeared on the screen, titled "Anti-Cult Special Forces Weapon".

The gun looks plain and simple, with a rough appearance that doesn't attract any attention.

But it is precisely this weapon that has left a significant mark on history books.

It allowed 130 million people in Japan and 8 billion people worldwide to witness history.

The greatest skill lies in its simplicity, and a heavy sword has no edge; that's all there is to it!

Based on the blueprints, Gu Lang began collecting the necessary raw materials.

He went into the factory and removed a double-unit oscillating toggle switch from the machine control table.

They cut another piece of PVC partition from the toilet.

They rummaged through the car and found a power bank they had looted. After opening the casing, they obtained four 18650 lithium batteries.

Back in his office, he removed a piece of the office baseboard and cut it to the appropriate size.

The barrels of the two homemade guns were removed, yielding two DN20 seamless steel pipes.

Finally, the trigger assembly on the grip of the homemade gun was removed and placed on the desk.

With all the materials ready, Gu Lang took out his toolbox and began the modification work.

He placed the two gun barrels side by side, separated by a PVC partition.

They were tied together to the wooden board with black super duct tape.

Then, using self-tapping screws, the wooden board was fixed to the handle of the homemade gun.

At the front of the grip, a four-pack of 18650 batteries is also secured with black strong adhesive tape.

The original trigger position was used to fix the double-mounted toggle switch.

One end of the switch wire is connected to a battery pack, and the other end is connected to the original firing port on the gun barrel.

After fixing the original front and rear sights of the homemade gun, a two-shot homemade gun is completed.

Gu Lang printed out a target and pasted it on the outer wall.

The gunpowder and lead balls were loaded onto the ramrod, and the battery switch, which served as a safety device, was pressed.

After aiming at the target, I turned on the head-shaking switch.

The gunshot rang out, a thick plume of white smoke billowed from the barrel, and several holes appeared in the target paper.

He took a dozen or so steps forward and readjusted his aim.

After the second shot rang out, the target was instantly riddled with holes.

"The first shot announced my arrival, the second shot announced your departure."

Mikami-san, I wonder if Sakura, your hometown, will ever bloom again.

With a sigh, Gu Lang reloaded the ammunition and put away the replica "Abe no Che".

Compared to before, the modified gun represents a significant improvement.

The original matchlock ignition method has been upgraded to electronic ignition.

This means that there is no need to light the fuse with an open flame before firing.

Not only can it be used anytime, but it can also be used in humid environments.

Judging from the bullet spread, this gun is very suitable for use as a shotgun at close range.

The lead beads used are about 8 millimeters in diameter.

Equivalent to the US No. 0 buckshot, it is sufficient to hunt large animals.

One loading can hold 12 pieces.

It has a near 100% hit rate within a 10-meter range, a very high hit rate at 20 meters, and its power is quite astonishing.

In various shooting games, the power of shotguns has actually been severely reduced.

The game character only loses health; their actions are not affected until they lose their last drop of health.

In reality, however, a person will be injured if shot, and will gradually lose their fighting ability.

Compared to more powerful rifle bullets, the only difference is between dying instantly and lying down to die.
