Wasteland Survivalist: A Scientific Guide to Post-Apocalyptic Survival

It was already 5 p.m., so we took advantage of the fact that it wasn't dark yet.

Gu Lang replaced the last battery in the drone and began exploring westward.

The official standard battery life of the Mavic 3 Pro is 43 minutes.

However, this result was obtained in a windless environment.

Taking into account external conditions such as wind direction, wind speed, and temperature, the actual flight time is less than 40 minutes.

In addition, the system will forcibly retain 20% of the power to prevent the plane from crashing and injuring people due to power outages in the air.

In addition to battery wear and tear, the actual usage time is only about 30 minutes.

During the first two flights, Gulang discovered that there were some buildings scattered in the nearby ravines.

After some reconnaissance, he finally found the campsite for the night.

The car sped along the desolate mountain road on the outskirts of the county town.

As dusk fell, the car headlights finally illuminated a sign with white background and black lettering.

"Qingyuan County Medical Waste Disposal Center".

The area is surrounded by a wall, topped with barbed wire and infrared detectors.

A heavy silver iron gate at the entrance was tightly closed, secured with a large iron lock.

Gu Lang got out of the car and pulled out a crowbar from under the passenger seat.

Feeling the cold metallic touch, he wedged the flat tip of the crowbar into the lock.

"Crack—bang," the iron lock fell onto the cement floor.

He pushed the iron gate open completely and found that infrared grating detectors were also installed on both sides of the entrance.

However, due to the power outage, all operations have now ceased.

The building behind it sits alone deep in the mountain valley.

Besides a few rows of low bungalows, there is a large factory building big enough to accommodate trucks.

The surroundings were deathly silent, with only the monotonous sound of sand and gravel being whipped up by the wind and slapping against the metal sheet.

Gu Lang just conducted a thorough search using a drone.

It has been confirmed that the treatment center is completely empty.

The buildings here don't look very old; they were probably built specifically for the COVID-19 pandemic.

He walked over, lifted the floor latch, and opened the factory door.

A stale, icy smell mixed with strong disinfectant hit me.

The truck drove into the factory, its headlights illuminating the outline of the interior.

Back in the courtyard, Gu Lang confirmed that no one was following him, then closed the iron gate at the entrance and re-secured the doorknob with wire.

Then, he picked up the crowbar again and headed towards the row of dark, bungalows.

The target this time is the door with the "Administrative Office" sign.

With another muffled thud, the wooden door opened.

After Gu Lang went inside, he turned on his headlamp and began rummaging through drawers and cabinets.

In a drawer, he finally found what he needed.

Two unremarkable little booklets.

The covers read "Dangerous Goods Road Transport Permit" and "Medical Waste Transfer Manifest Registration Book".

Continuing to search, I found another roll of yellow label stickers.

Upon opening it, there was indeed a huge black circle clover graphic drawn on it, representing a biohazard.

Below the sign are the words "Warning!", "Medical Waste", and "Infectious Waste".

This is exactly the kind of disguise prop that Gulang desperately needs right now.

He immediately took the items and went back to the truck.

After peeling off the paper backing, the sticker was placed in a prominent position on the car body.

After taking a few steps back and observing the surroundings, I felt that something was missing.

After thinking for a while, Gu Lang slapped his thigh.

I went back to the office and found a few power strips.

After being relayed through multiple layers, the 220-volt power output from the light truck was connected to the office.

An office computer starts up, and the screen lights up.

He opened a blank document, typed one word at a time on each page, and then turned the font size to the maximum.

Soon, a printer started running.

Gu Lang picked up the freshly printed, still-warm printing paper.

I sat down at my desk and started carving with a ruler and a craft knife.

Next, the cut-out printouts were pasted onto the outside of the light truck's cargo compartment.

He then took out the black spray paint he had obtained from the auto repair shop and started spraying it.

With the printed paper torn off, everything was done.

The words "Medical Waste Transport Vehicle" appeared in bold black letters.

"This looks much more professional."

Gu Lang shook the spray paint can and sprayed the last bit of black paint onto the rear ram.

The area was previously hit hard by falling rocks, leaving a dent.

"That's terrifying. If it hit someone, there would be pieces scattered all over the place."

He laughed as he tossed away the spray paint can.

The car's high beams were turned on, the beams piercing through the dust suspended in the air.

A silent hill appeared, made up of sealed turnover boxes of different sizes and specifications.

The yellow plastic boxes all bore the same biohazard symbol.

Further ahead, there were several large pieces of equipment that had stopped operating.

Upon closer inspection, it turned out to be a material collection and conveying machine, a high-temperature steam sterilizer for feeding, and a waste crushing and baling machine.

In addition, there are disinfection and cleaning systems for turnover container vehicles and sewage collection and treatment systems.

Deep inside the factory, several unopened yellow medical waste bags were neatly stacked on pallets.

On the workbench next to it, there was a whole bag of special seals.

The innermost part contains a disinfection room and a changing room, where several protective suits are also hanging.

Unlike the disposable medical protective equipment previously obtained in temporary makeshift hospitals.

All of these are high-standard, fully enclosed heavy-duty protective suits.

It offers a much higher level of protection and can be reused after disinfection.

Unfortunately, there are only three sets available.

Without the slightest hesitation, Gu Lang packed it up and took it away.

Next, he unloaded all the valuable supplies from the vehicle.

They were stuffed one by one into these yellow plastic bags, which symbolized deadly pollution.

Next, he unloaded the sterilized crates.

Stuff the sealed yellow bags one by one into the bag until it is full.

With a "click," the lid was closed and finally sealed.

The glaring biohazard sign on the outside of the crate now served as the perfect camouflage.

After loading all the boxes into the cargo compartment, Gu Lang took off his medical protective suit and rested for a while.

Then they found the bag of blood-stained gold jewelry and put it in the transfer box to wash it.

The blood was smeared on the protective suit and mask, sealed, and placed on the outermost side of the cargo compartment.

After closing the tailgate, my last bit of strength finally gave out.

Gu Lang cooked a bowl of noodles and ate it with canned curry beef.

My eyelids felt as heavy as if they were weighed down by iron blocks, and every blink was incredibly difficult.

But he knew he couldn't just rest right away.

He pinched himself hard, forcibly dispelling the black mist in front of him.

He struggled to his feet and dragged his leaden legs into the duty room.

Gu Lang quickly found an alarm control panel that matched the infrared grating detector.

There is also a 12-volt power supply next to it that provides power to the main unit and the outdoor detectors.

Plug the power cord into the power strip, and the detector on the wall resumed working.

The detector is shaped like a series of pure black cylinders.

Each cylinder contains four lenses, capable of emitting four infrared beams invisible to the naked eye.

When a beam of light is blocked, the system will determine that it is blocked by fallen leaves or small animals.

An intruder is only identified if two or more infrared beams are blocked simultaneously.

This triggers an alarm, sending a wireless radio frequency signal to the host.

Gu Lang arrived at the door and tested himself with his body.

A loud alarm sounded immediately, exceeding 90 decibels, in the duty room.

After resetting the alarm system, he moved the weapons into the duty room.

After a quick wash, I fell asleep, completely exhausted.
