Wasteland Survivalist: A Scientific Guide to Post-Apocalyptic Survival

I spent some time test driving them, and most of the cars were in poor condition.

Some of them couldn't even start; only one black sedan was in good condition.

It was so fun to drive that Gu Lang couldn't help but drive around the parking lot a few more times.

After turning off the car, he began collecting gasoline.

Gu Lang found a plastic tube and inserted it into the car's fuel tank.

Using the siphon effect, gasoline is transferred into two 30-liter gasoline containers.

Each car typically only has a few liters of gasoline, but fortunately, little by little, it adds up.

It took more than an hour, but they still managed to collect over 50 liters of gasoline.

In addition to gasoline, I also found several bottles of fuel additives, synthetic motor oil, windshield washer fluid, and oil film cleaner.

Gu Lang decided to keep the entire 30-liter barrel of gasoline for later use.

After filling the light truck's fuel tank, there were still 5 liters left over.

After thinking for a moment, he poured all the gasoline into the beer bottle.

They also added engine oil, rubber blocks, flour, and sugar to increase the viscosity.

After sealing the bottle with the stopper, Gu Lang found the sodium block he had obtained from the school laboratory.

After carefully removing it from the oil-sealed bottle with tweezers, I cut off twelve small pieces.

After wrapping the surface with a layer of cotton wool, attach it to the bottle surface with waterproof tape.

This way, the bottle will break once it is thrown.

When sodium comes into contact with some water and organic matter in the bottle, an exothermic reaction occurs.

The flame is ignited by high temperature.

Common methods include using a lighter to light a strip of cloth.

It's so primitive that Gu Lang would be embarrassed to show it to others.

In the end, he made a total of 12 Molotov cocktails.

Continuing his search, Gu Lang opened the trunk of the Land Rover.

They also found an electric air pump and an emergency starter.

The former can quickly inflate tires when the tire pressure is too low.

The latter can assist in starting the engine when the car battery voltage is low.

After removing five dashcams, he ended his search of the vehicle.

Gu Lang, carrying a flashlight and a crowbar, arrived at the office area.

The vending machine overturned on the ground, and all the goods inside were gone.

The office was deserted; even the bottled water had been taken away.

After exploring the second floor, all that was left was trash; no food or water was found.

The third floor is also a parking lot, with only a few zombie cars parked there.

Gu Lang went down to the first floor and looted several new mobile phones, power banks and various accessories from a mobile phone store.

There are still many auto repair shops and car washes here, most of which have long since closed down.

They pried open several roller shutter doors and entered a shop called Xun Jie Auto Repair.

He finally found what he was looking for: a gas welding machine.

Alarm cans were placed at the building entrance.

Gu Lang drove the light truck into the auto repair shop and immediately began modifying the vehicle.

In summarizing the attack, he discovered that the light truck was missing a crucial piece of equipment.

That's the ram that can break through roadblocks.

During the subsequent journey south, he would inevitably have to outwit and outmaneuver various bandits and highwaymen.

The vehicle's obstacle-breaking and collision-avoidance capabilities urgently need improvement.

Gu Lang plans to imitate post-apocalyptic movies by installing triangular ramming corners on both the front and rear of the car.

The first problem to solve is the raw materials.

The core materials required are three types: I-beams, channel steel, and steel plates.

He remembered that there were many parking sheds outside the trading market, which were made of these steel structures.

So they immediately found a hand-pushed flatbed cart and put all the tools on it.

With the flood imminent and time running out, he planned to evacuate the area at daybreak the next day.

It was still raining outside, so Gu Lang put on a raincoat over his protective suit and went out to disassemble the raw materials.

At first he was hesitant, but as it got darker, he stopped worrying about anything else.

"It's just a slightly dirty hem."

Gu Lang consoled himself and worked for another hour or so.

They finally collected enough steel before nightfall.

They located a fire hydrant and rinsed the protective suits and raw materials.

Gu Lang changed his clothes and quickly got to work.

The gas welding equipment stands next to the maintenance ditch.

The pressure gauge on the acetylene cylinder is yellowed, and the pointer is stopped at the 50% mark.

The last time a light truck was modified, Gu Lang watched the entire process as the mechanic operated the truck.

He even gave the other party a pack of cigarettes and asked them to teach him how to use them.

After preparing the protective equipment, he followed suit and turned the acetylene valve three times.

Adjusting the pressure to 0.06 MPa, the lighter emitted a blue-core flame.

He then turned the oxygen valve to 0.7 MPa, and the flame suddenly turned white.

The flame tip pressed against the waistline of the I-beam, and molten slag dripped down like blood, cutting the six steel beams into 120-centimeter lengths.

With the help of welding rods, the two triangular frames were gradually assembled on the cement ground.

The base is 80 cm long, the two sides are each 100 cm long, and the angle between the apex is 30 degrees.

Inside the triangle, a "cross-shaped support frame" is welded with channel steel to prevent deformation from impact.

The welding torch was placed on the joint, and the molten steel boiled and filled the gap.

After completing the main framework, he covered the surface with a layer of steel plate.

Next, the original bumper was removed, exposing the front and rear beams of the chassis.

Gu Lang measured the existing holes on the frame and began making the mounting base.

He cut out several 10-millimeter-thick steel plates and welded them to the base of the triangle.

Connect the drilling rig to the vehicle's power supply and drill bolt holes in the steel plate according to the hole positions on the vehicle frame.

They cut out 10-millimeter-thick rubber pads from discarded tires and covered the bolt holes as a buffer layer.

Since he was alone, Gu Lang had to use both a jack and a hand-operated crane to support the ram.

He aligned the frame with the mounting holes and slowly pushed it closer.

After inserting the M12 bolt, tighten it in three stages using a torque wrench, following a diagonal sequence.

The two rams were finally installed, completely replacing the flimsy bumper.

The weld looks rather rough, far less aesthetically pleasing than the uniform fish-scale pattern achieved by experienced welders.

Just to be on the safe side, he tested it by tapping it with a hammer.

Fortunately, no porosity was found after the welding slag was removed.

No cracking sound was heard during the tapping.

"It's quite sturdy; hopefully it'll last."

Gu Lang let out a long breath, glanced at his watch, and saw that it was already past 3 a.m.

After finally spraying a layer of matte black paint on the ram, tonight's work was all finished.

After searching the toolbox in the auto repair shop.

He ate a simple late-night snack and finished washing up.

Gu Lang parked the car back on the second floor and disguised it simply with a sunshade.

He crawled into the car, took a potassium iodide lozenge, and fell asleep fully clothed.

The next morning, Gu Lang, having slept soundly all night, regained his strength.

After finishing breakfast, I went to the window and saw that the rain outside had stopped.

So he removed the canned food containers from the building entrance.

The alarm system was deployed at the entrance of the trading market.

The biggest drawback of canned food alarms is that they are not waterproof.

Once it gets wet from rain, the sound becomes very quiet.

Just as Gu Lang was busy setting up the fishing line, a buzzing sound suddenly came from the sky.

He looked up and saw a drone hovering overhead.

Realizing he had been exposed, Gu Lang quickly rushed back into the building.

However, it was too late; they had just returned to the second floor.

Two cars had already rushed downstairs; one was an SUV.

The other one was none other than the bread truck we encountered yesterday.
