Wasteland Survivalist: A Scientific Guide to Post-Apocalyptic Survival

Gu Lang was awakened by strange noises.

"Sobbing... um... sobbing... ah..."

The sound seeped in close to the earlobe.

As thin as a spider's thread, carrying cold, damp air, it penetrates the eardrum.

It then spread down the spine, raising goosebumps all over Gu Lang's skin.

This sound is definitely not something that can exist in nature.

It has such a "human" feel to it.

It's like a woman whose mouth and nose are covered.

The voice that comes out in extreme fear or grief.

A series of intermittent sobs squeezed from the throat.

Gu Lang's heart pounded wildly in his chest, and he suddenly sat up.

He gripped the concrete tamping rod tightly and carefully inspected the entire room.

There were no signs of intrusion, nor was anything unusual observed.

The sound seemed to be coming from the doorway of the room.

Gu Lang picked up a flashlight and tiptoed over.

Place the pestle at the doorway and slowly unlock the safety chain lock.

As he switched the flashlight to strobe mode, he suddenly flung open the door.

The strange noises disappeared immediately, and the corridor became quiet.

There was only an indescribable eerie atmosphere.

Upon going outside, there was no sign that the fishing line or glass shards had been disturbed.

"This is really strange, could it really be a ghost?"

Picking up his phone, Gu Lang quietly asked the viewers in the live stream.

"Brothers, did you hear that sound just now? It sounded like a woman crying."

There are only a handful of people still awake in the live stream room.

Only one comment appeared: "The streamer is forcing himself to do something when he has nothing else to say, so he's starting to create suspense."

Just as Gu Lang was beginning to suspect that the poor air quality here was causing him to hallucinate.

As soon as I sat down on the bed, that eerie voice rang out again.

Gu Lang strapped the phone holder to his chest and went to the door again.

"Holy crap, something's finally happened."

"Here it comes, here it comes."

"I turned the volume up to the maximum, and I could really hear crying."

The number of comments on the screen increased rapidly.

In front of a large audience, he opened the door.

The sound disappeared again.

Gu Lang was filled with fear as he looked at the comments; he was now certain that this was not a hallucination.

"Something's not right. Did I really run into trouble this time?"

The live stream was a huge success, with viewership skyrocketing.

Because the signal in the room was poor, I could only get one bar of 4G signal.

The video bitrate of the live stream is very low, and the clarity is very poor.

In addition, the lighting was poor, and the camera was a mobile phone.

The screen is full of noise, giving it a vintage horror movie feel.

Just as Gu Lang sensed something was wrong and was preparing to pack his things and run away...

That man reappeared in the live stream.

He's here! He's here!

The top-ranked tycoon, Ninth Master, has arrived with his rocket.

"Don't leave."

It remains as concise and to the point as ever.

Speaking with money is a sign of strength.

Watching rocket after rocket fly by in the live stream.

Gu Lang immediately abandoned the idea of ​​leaving.

Just kidding, it's just listening to ghosts cry.

Materialist warriors are fearless.

With so much money to be made, he could laugh at ghosts without hesitation.

The strange noises continued for some time, sometimes intermittently.

In the live stream, the comments section had already moved from discussing Master Zhang to quantum mechanics.

Gulang launched a voting campaign.

The most popular explanation right now is the one proposed by Ninth Master: "Schrödinger's ghost".

It is said that the female ghost was in a chaotic state of being either alive or dead.

As soon as the door is opened, it collapses and disappears due to the observer effect.

If you close the door, you will return to the doorway of the room due to your resentment before death.

Gu Lang was too tired to reason anymore; he was exhausted.

He would only get up to open the door as a gesture when he saw the rocket.

Previously, in order to rule out the possibility that Gu Lang had forged the document, Ninth Master had already had him film the entire place, inside and out.

As a result, Gu Lang received another wave of gifts.

"If everyone did this, then proving one's innocence wouldn't seem so unacceptable."

He smiled as he watched the gift value steadily increase.

After all that fussing around until after 3 a.m., Gu Lang was just too tired to stay awake any longer.

I lay back in bed and fell fast asleep.

"You can even fall asleep like this? Wow, I'm following you."

"Is the streamer really asleep? The gloomy atmosphere here is practically leaping off the screen."

"Don't die in my phone, run away, please."

The scene turned into Gu Lang sleeping on live stream, with tens of thousands of netizens listening to his snoring gradually drowning out the strange noises.

There's actually only one reason why Gu Lang can sleep so soundly.

He has already solved the case, but he doesn't want to tell anyone.

Once the truth is revealed, many people will be quite disappointed.

All the previous confident assertions will be proven wrong on the spot.

He has his own professional ethics and absolutely cannot let the top-ranked fan embarrass him.

The strange noise was actually a trembling sound emanating at a chilling frequency.

If you listen carefully at the scene, you will find that the sound is coming from above.

The source is located in the indoor ventilation opening above the doorway.

Gu Lang used a camera angle trick during his live stream to avoid being seen by the camera.

He secretly wet his fingers with saliva, stood on the cabinet, and stretched them out.

Soon I felt a very subtle airflow.

This is the truth behind the ghostly cries at midnight.

The abandoned shopping mall has been without power for a long time, which is why the air is still circulating.

It seems the non-powered vent caps on the roof are still functioning.

This rotating metal sphere is made entirely of fan blades.

It will start to rotate automatically as long as there is wind blowing outside.

The air in the room is drawn out, and ventilation is achieved by using negative pressure.

When airflow passes through the gaps in the vent, it produces a sound that sounds remarkably like a child's or a woman's cry.

This is an instrument created by a series of coincidences.

There are no windows in the room, so every time the door is opened...

The pressure difference between the inside and outside will change, and the airflow speed will also be adjusted accordingly.

The strange noise disappeared after the vibration frequency changed.

The person Gu Lang admires most now is that Taoist priest who puts up talismans.

I guess they switched from civil engineering.

This major is really bad for job prospects.

It is only natural to actively engage in side hustles to save oneself.

Gu Lang now fully understands the layout of the room.

The other talismans were glued on with paste.

Those five-element ornaments are used to rip people off and generate revenue.

These are all smokescreens used to conceal the real core trade secrets.

The most crucial step is actually just the talisman placed at the entrance to ward off evil spirits.

The Taoist priest specially covered it with transparent tape, sealing the gap tightly.

Gu Lang had to put in a lot of effort to tear it off.

In fact, simply applying some glue to that spot will solve the problem of ghostly cries at night.

The Taoist priest was able to see through the truth at a glance and use magic to exorcise the ghost, which clearly shows that he was highly skilled in Taoism.

He should at least be a first-class construction engineer specializing in ventilation and water supply.

In short, a first-class Feng Shui master.

Gu Lang woke up on Sunday morning of the next day and picked up his scalding hot phone.

Looking at the large number of gifts and countless comments in the live stream, he smiled strangely and closed the live stream.

From then on, another urban legend was added to the local area.
