Wasteland Survivalist: A Scientific Guide to Post-Apocalyptic Survival

Over the next few days, Gu Lang went to the ruins of surrounding towns and villages to film videos.

He did another live stream of an outdoor adventure, but unfortunately he still didn't see the aurora.

Fortunately, having a car has greatly reduced the physical exertion.

Mini bread carts are small in size and have ample ground clearance.

Aside from its slightly weaker off-road capabilities, it has excellent passability and is very easy to park.

The interior space is large enough to accommodate both living and cargo transport.

For him, it's more practical than a motorhome.

The Northeast is sparsely populated, and wild animals often roam in remote areas.

Carrying weapons for self-defense means you can't get through security.

Without public transportation, it's practically impossible to get around.

Buying this car solved his immediate problem.

However, Gu Lang still discovered a few problems during the driving process.

First of all, the battery life is poor. After driving more than 190 kilometers, the battery was almost depleted.

Compared to the advertised 300km range on a full charge, the battery has degraded by one-third.

This is even at a daytime temperature of 20 degrees Celsius.

If the weather gets colder, the battery heating function needs to be turned on.

The actual driving range will continue to decrease.

In the cold north, this is a fatal flaw.

However, it's still early before winter arrives.

According to Gu Lang's live streaming plan, by then he would have already traveled all the way south.

Secondly, the speed is too slow, with a top speed of only 80 kilometers per hour.

Fortunately, he doesn't need to race; he just needs to be able to drive on the highway.

Driving this thin-skinned minivan too fast is practically suicide.

The last question has a rather significant impact.

This car model is too old and doesn't have DC fast charging; it only has a slow charging port.

It takes 4 hours to fully charge an AC charging station.

If you want to save money, use the car's built-in charger.

It takes up to 7 hours to fully charge when using a standard 220V household outlet.

That would be a huge waste of time, especially considering his route.

Finding a charging station in the wild is really difficult.

To solve this problem, Gu Lang drove his car into a car repair shop.

"Sir, have the solar panels been delivered yet?"

"Yes, I've received it. I'll modify it for you now."

The mechanic stood up and pointed to the side.

"The brackets are all detachable; don't weld them shut."

"Don't worry, I specialize in modifications here. This is even simpler than an electric awning."

Gulang acquired five second-hand monocrystalline silicon photovoltaic panels locally.

Each piece is 2.3 meters long, 1.2 meters wide, and 30 millimeters thick.

It weighs 25 kg, has a conversion efficiency of 21%, and a peak power of 550 watts.

It can be stacked and installed on the roof using brackets.

Even when the vehicle is in motion, only the topmost photovoltaic panel can generate electricity.

However, when the vehicle is parked, the four panels below can be pulled out in all four directions.

At this point, the theoretical maximum power generation capacity can reach 2750 watts.

Of course, the actual power is usually lower than the nominal value.

Light, temperature, dust, angle, and obstruction can all have an impact.

Because photovoltaic panels generate low-voltage direct current.

An inverter is also needed to convert the electricity into 220-volt alternating current.

Therefore, the circuit loss will also be relatively high.

Calculated based on an effective sunshine duration of 5 to 6 hours.

The average daily power generation varies between 5 and 25 kilowatt-hours depending on the weather.

The car comes with a 39 kWh lithium iron phosphate battery.

After deducting losses, there is actually a capacity of 26 kilowatt-hours remaining.

On a sunny day, it can be fully charged in about a day, but on a rainy day, the charging power is negligible.

After the modifications were completed, Gu Lang also had the auto mechanic do a full cleaning and maintenance of the car.

I replaced the air conditioning filter, brake fluid, and antifreeze, and added lubricating oil and windshield washer fluid.

Some minor issues, such as malfunctions, were also fixed.

In recent years, there has been a severe overcapacity of photovoltaic panels, and prices have fallen below the critical point.

In Europe and America, some people have even used solar panels as balcony partitions, replacing iron railings.

The photovoltaic panels, brackets, inverters, and circuit accessories that Gulang purchased cost a total of just over three thousand yuan.

Including the 800 yuan for modifications and maintenance, he has invested a total of more than 9,000 yuan in this car.

By the time everything was finished, it was already 7 p.m.

The remaining money was all spent, turning into equipment and supplies for the vehicle.

The most expensive item was a Junxing brand crossbow.

The products were originally intended for export, but were smuggled out of the factory by someone.

In China, this would be considered an illegal weapon.

The mechanic realized he was heading into the mountains.

After chatting for a few minutes, I tried to sell him this secondhand weapon.

Compared to bows, crossbows are much easier to use.

Once he got the hang of it, he was able to hit exactly where he pointed.

Having become penniless again, Gu Lang had no choice but to intensify the filming.

They rushed to their next destination overnight: an abandoned middle school rumored to be haunted.

After the last time, we received a huge gift harvest.

He has developed a bit of a path dependency on "paranormal live streams".

It was already dark when Gu Lang drove around the school wall with his high beams on.

He was honking the horn frantically while chatting with viewers in the live stream.

"Hey guys, let me teach you a little trick."

Before entering such a place, you must make some sounds that are not natural.

This helps avoid harming small animals when entering the enclosure and also prevents you from being harmed by larger animals.

For example, the Northeast Golden Shaded or the Siberian Hamster.

Although this area is abandoned, the cell phone signal is surprisingly good.

The live stream went very smoothly.

After getting off the bus, Gu Lang pushed open the dilapidated iron gate and went inside.

It was pitch black all around, and the campus looked desolate and dilapidated.

"Hello! Is anyone there?"

He called out a few times, but no one answered, and he didn't see any other homeless people.

Just in case, Gu Lang took out three steel pipes from his bag.

Align with the threaded end and rotate to connect.

After removing the protective cap at the top, a boar spear is assembled.

Having the tools in hand put him at ease.

If you encounter a homeless person, you can reason with them.

Even if we encounter a wild boar, we have a fighting chance.

"Brothers, after this school was abandoned, it seems to have been used as a makeshift hospital for a period of time."

The teaching building was littered with discarded cardboard boxes.

Inside, there are various isolation and protective equipment, including high-standard gas masks.

The blackboard on the podium was covered with all sorts of "I was here" graffiti.

There is still a blackboard at the back, filled with messages left by past students.

It is naive yet full of vigor, exuding the flavor of youth.

Seeing this scene, the live stream chat became very active.

Gu Lang recalled his student days, shaking his head with a wry smile.

Pick up the chalk and compose a poem:

"I wanted to buy osmanthus flowers and share wine, but it will never be the same as the carefree days of my youth."

Then I invite the east wind to embrace the bright moon, for spring will not allow me to look back.

Retracing the paths of my childhood, the endless snow has turned my hair white.

The withered willows are silent, the wild geese do not stray; the west wind has brought autumn once more.

After leaving the classroom, Gu Lang arrived at the student dormitory.

As soon as I stepped into the boys' dormitory building, I heard a series of "hehehe" sounds.

It sounds like the weird laugh of a villain in an old TV drama.

His voice had a metallic, hoarse quality.

The echoes reverberated repeatedly in the dark stairwell, sending chills down one's spine.

Having learned from his previous experience, Gu Lang performed again.

After swindling a large number of gifts, he leisurely went upstairs to investigate.

After observing for a long time, he concluded that the sound was not made by a human.

Laughter rang out precisely every 10 minutes, lasting for 30 seconds before stopping.

It's too predictable; it can't be a madman laughing.
