Wasteland Survivalist: A Scientific Guide to Post-Apocalyptic Survival

Why do boys' dormitories scream in the middle of the night?

What secrets lie behind the abandonment of the school?

Behind all this lies the distortion of human nature?

Or is it a decline in morality?

Is it a sexual outburst or the helplessness of hunger?

Please tune in to our live stream tonight at midnight for our annual blockbuster, "Getting Closer to Metaphysics".

Let's follow the camera and step into the inner world of a psychopath...

Gu Lang continued his antics while following the sound.

The dormitory door rattled and creaked in the wind.

As they stepped through the broken glass to reach the top floor, laughter erupted once more.

The sound was coming from the room at the end of the corridor.

The waterlogged ground reflected an eerie light.

Gu Lang slowly walked over, and a slogan appeared at the entrance.

"Communication facilities are protected by law! Those who damage them will be held accountable!"

The dormitory roof was originally used by a mobile operator to transform it into a communication base station.

Outside the base station, the pipes of a multi-split air conditioning unit meander like a snake.

Gu Lang removed the insulation layer, and the truth finally came to light.

The strange laughter was coming from the base station's air conditioning system.

According to the analysis of the expert commenter.

It's probably due to improper equipment maintenance; air got into the water pipes.

The air conditioning compressor starts and stops on a timer, and the multi-split system drains water intermittently.

The resonance of air and water flow amplifies the noise.

This produces a vibrato effect that fluctuates in pitch, like the mad laughter of a demon.

The truth behind the rumors of a haunted school has been revealed, and viewers are saying "it's so boring."

Most of the viewers left the live stream in an instant, and Gu Lang also prepared to end the broadcast and leave.

Suddenly, out of the corner of his eye, he noticed that the sky outside the window seemed to have changed in some way.

The human retina contains two types of photoreceptor cells.

Cone cells responsible for color perception in bright environments.

And rod cells, which are responsible for visual perception in low-light conditions.

Rod cells are 1000 times more sensitive to light than cone cells.

It can distinguish even fainter light in dim environments.

These rod cells are mainly concentrated in the peripheral area of ​​the retina.

That is, the area covered by peripheral vision.

Therefore, when in a low-light environment.

Gu Lang would also actively use his peripheral vision to observe the dark areas.

Allow the light to fall on the area where rod cells are densely packed.

In order to obtain a more acute visual perception.

He turned off his flashlight and waited for his night vision to return.

After a while, I looked up again.

The aurora borealis, which I had been looking forward to for so long, finally appeared clearly in my field of vision.

Gu Lang quickly climbed the ladder to the roof and began taking pictures.

Several dim green lights kept drifting in the sky.

As time went by, it gradually stretched across the entire sky.

The waterfall of light cascaded down like liquid jade, its edges tinged with a pale purple glow.

Gu Lang exclaimed with delight, completely captivated by the breathtaking scenery.

The only downside is that the phone's camera capabilities are too weak.

It is impossible to fully share the magnificent scene with the audience.

Suddenly, crimson ripples burst forth from the top of the green screen.

The red light, like a river of lava, meandered and spread across the emerald curtain.

The red and green hues blend together, making the sky resemble an interstellar battlefield.

After another ten minutes or so, a radial corona appeared.

A beam of blue-purple light pierced the sky like lightning.

Then, the entire light curtain tore vertically.

Scarlet and emerald hues rolled together, merging into a bluish-white glow.

The intense light illuminated the entire school.

Just then, a cracking sound came from beside my ear.

Gu Lang put down his phone, which had suddenly lost signal, and ran to the edge of the roof.

In the distance, a high-voltage transmission tower is entwined with a huge blue-white electric arc.

On the nearby utility poles, strange orange-red fireballs rose up.

The transformers exploded one after another, like fireworks on New Year's Eve.

Molten metal fragments flew out like sparks from a hammer blow.

"Is it magnetic induction current?"

He recalled the "1989 blackout at Quebec University of Technology" mentioned in a disaster documentary.

Geomagnetic storms triggered by solar storms can disturb the magnetic field of Earth.

This can cause DC surges in long-distance power transmission lines.

These currents far exceed the grid's design capacity.

This leads to magnetic saturation of the transformer core, overheating of the coils, and ultimately, burnout of the equipment.

Those dazzling "iron flowers" were actually the bursting of the blood vessels of modern civilization.

The lights of the distant city were extinguished in large sections, and there was no longer any light pollution to be seen.

Darkness spread across the fields like asphalt, with only the aurora borealis still dancing enchantingly in the sky.

"not good!"

Gu Lang roared and lunged at the ladder.

He rushed downstairs and got back into his car.

To save electricity, the bread cart is turned off.

He opened the car door and began inspecting the various electronic products.

Fortunately, the equipment, including the vehicle, was still functioning normally.

Only the inverter of the photovoltaic power generation system experienced overheating.

Just in case, Gu Lang disconnected the circuit to the photovoltaic panel.

He opened the glove box and pulled out the vehicle's owner's manual.

This book was still in its plastic wrapping, and this was the first time it had been opened and read by someone.

From the above, Gu Lang learned some important information.

Before new energy vehicles can be put on the market, they must pass the national mandatory electromagnetic compatibility test.

Core components such as battery packs and motors will use metal shielding and filtering circuits.

The addition of a metal body creates a Faraday cage effect.

It can withstand moderate-intensity electromagnetic pulses.

The electromagnetic disturbances generated by solar storms are different from military EMP (electromagnetic pulse) attacks.

It is low-frequency non-ionizing radiation, and its energy is insufficient to directly burn out automotive-grade electronic components.

Mobile phones, computers and other devices also generally have built-in electromagnetic shielding designs.

Furthermore, it is small in size, has short circuits, and is not easily induced by strong currents.

Letting out a long breath, Gu Lang put down the instruction manual and began to think.

Although my side was basically unaffected.

However, solar storms cause far greater harm to society.

It could paralyze the power grid and destroy satellites.

Disturbing the ionosphere disrupts wireless communication.

Damage to a submarine fiber optic repeater caused an internet outage.

The duration can range from a few hours to several days.

The higher the latitude, the greater the impact.

"What bad luck to run into something like this in the northernmost part of the Dragon Kingdom."

Gu Lang complained about his luck.

My phone can no longer receive a signal, and even GPS location services are no longer working.

He took off his headlamp and began to analyze his current situation.

In a survival situation, the priority of each element is divided into nine levels, all based on the "Rule of 3".

First level: Air.

Instant lethal threat; survival time less than 3 minutes.

Brain cells die if a person is deprived of oxygen for 3 minutes.

To avoid toxic gases in confined spaces, use protective measures.

They should be moved to upwind or higher ground first.

Take timely shelter from deadly threats such as fire smoke and nuclear contamination dust.

There is currently no threat to Gulang in this regard, so it can be ruled out for the time being.

Second level: Shelter and body temperature maintenance.

Short-term lethal threat, survival time less than 3 hours.

In extreme environments, whether it is severe cold or scorching heat.

Without shelter, one can die from hypothermia or heatstroke within 3 hours.

Gulang currently has one tent, one bread truck, and the abandoned school also serves as a good shelter.

It is currently early July, and the temperature in the north is quite pleasant.

There's no need to worry about heating or cooling off; that's not a problem either.
