Survival in the apocalypse: I exploited a bug in an infinite dungeon.

In order to enable more humans to survive, the people in "Safe City" invented a small machine similar to an air purifier.

This machine contains a purification filter that can temporarily "purify" the surrounding radiation.

To allow people to live normal lives without wearing protective suits.

It sounds like an "air purifier" from before the apocalypse.

Depending on the size of the purifier and the material grade of the filter inside, the machine's usage time and purification range will vary.

The humans in the base can continue to survive thanks to these machines and protective suits.

The base where Shi Jinwei was located was a medium-sized base, which was called "Anping City" before the apocalypse.

Now people call the base "Anping Base".

Like most post-apocalyptic novels, this world is cut off from water, electricity, and internet after the apocalypse.

Each city and base exists independently.

After the "purifier" was invented, the various bases would occasionally exchange information with each other.

However, due to scarce resources and shortages of supplies, they could only exchange information with other base cities during trade exchanges.

That's why Shi Jinwei's bracelet doesn't have a net.

When the old man saw that Shi Jinwei's bracelet didn't even have a local area network connection to the base, he became even more convinced of her "amnesia."

Even people from other bases couldn't possibly be completely ignorant of these basic facts.

He taught Shi Jinwei to connect to the local area network in the base and they even added each other as friends.

As long as the local area network in the base is still operational, communication can be achieved using the wristband.

Let's continue.

The world today is a world surrounded by radiation.

Humans mutated due to pollution, and the lucky ones became superhumans.

Similarly, plants and animals also mutate due to radiation.

However, their evolutionary direction is mostly towards physical strength, size, and accelerated reproduction, with few developing special abilities.

Humans can fight against them using firearms and superhumans.

"Is that what you just encountered?" The old man finished fiddling with the object in his hand and placed it on the table.

It was a small box, about the size of a palm, and you couldn't tell what was inside.

Seeing Shi Jinwei looking over, he smiled but didn't explain anything.

Just then, the auntie finished cooking and came out of the kitchen happily carrying three large bowls.

Each person had a large bowl filled with a dark, sesame-paste-like paste.

"Don't be disgusted, little girl. Every family here makes this kind of food." The aunt smiled apologetically at Shi Jinwei.

She didn't mind; she was just curious whether these foods contained radiation.

The old man picked up the small box on the table and gently pressed it.

The box emitted a green glow and beeped twice.

The old man took off his mask when he heard the sound.

The aunt also took off her mask.

The small box was a "purifier." Shi Jinwei looked surprised and then took off her mask.

The aunt was taken aback when she saw the fair-skinned little face under the mask.

She looked up at the old man, who shook his head at her.

The aunt didn't say anything more and continued to urge Shi Jinwei to eat.

Shi Jinwei took a bite, but it had no taste at all.

There was still room and food, and she didn't want to force herself.

He pulled out three fast food meals.

The aroma of food instantly filled the dimly lit room.

The two elderly people stared wide-eyed: "This? You're a superhuman?"

Shi Jinwei shook her head: "I don't know, I can't remember. I just wanted to eat something, and then I was able to take it out."

The aunt was so shocked by her words that she couldn't speak.

The old man looked at the food, said nothing, and gestured for his wife to eat first.

After the meal, the aunt cleared away the dishes, while Shi Jinwei asked the elderly woman about the details of the air purifier and the base.

The old man knew she was definitely not an ordinary person.

After thinking about it, I decided to tell the truth.

The manufacturing and sale of air purifiers are controlled by the higher-ups.

"The nation no longer exists; the city and base leaders are the highest ruling class," the old man said, picking up a small box and fiddling with it.

After finishing their meal, they put their gas masks back on.

The air purifier was also turned off and is no longer in use.

In the apocalypse, to become a ruler, besides having excellent management skills, one must also have capital.

It refers not only to money and power, but also to things that ordinary people don't have.

Air purifier technology is one example.

It is an essential item that all people in the end times are eager to obtain.

There are also "safety shields" that can isolate radiation.

In order to keep people willing to stay in a city or base, the higher-ups will naturally keep these technologies firmly in their hands.

Ordinary people who want air purifiers need to buy them from them.

Even powerful superhumans are no exception.

The city's high-ranking officials also regularly purchase air purifiers from other cities every month and sell them to ordinary people.

"But your air purifier isn't like that," Shi Jinwei interrupted the old man, pointing to the small box in his hand.

The old man smiled and said, "This little thing has a very simple structure; the main thing is that the filter inside is quite special."

The material of this filter is unknown; other cities and large bases also have their own research institutes.

Yet no research institute has been able to develop this substance.

Therefore, the city that supplied the goods could only grow stronger on its own and become the most prosperous city after the apocalypse.

Other cities and bases have also harbored ambitions towards it.

They were also afraid of going too far, failing to acquire the technology and even disrupting the trading, so they could only grit their teeth and let it grow bigger and stronger.

This old man was a researcher before the apocalypse.

His child died in the apocalypse, leaving him and his wife to eke out a living in the apocalypse.

Many ordinary people have awakened superpowers, and it's no surprise that the elderly have too.

However, he possesses a very special "purification" ability.

"My special ability can purify unusable filters."

As he spoke, he opened the small box and took out a piece of gray, cotton-like substance.

Then a warm light appeared in my hand, and the gray cotton wool slowly turned yellow.

Yellow turned white again.

This means it's purified.

Originally, the old man and his wife lived in another city.

The higher-ups discovered his special abilities and wanted to capture him for research.

Back then, there were no air purifiers, and protective suits were scarce resources.

Ordinary people can only eke out a living by hiding in bases and cities.

However, the old man and his wife traversed the desolate radiation zone, using their purification abilities to escape to the Anping base.

After that, the two changed their names and hid here to survive.

Of course, he could live a good life with his superpowers, but his wife is just an ordinary person.

He had a sore spot, and he was also afraid that if he were exposed, others would use his wife to threaten him.

The two decided to hide in the base's slums under assumed names.

The most important part of an air purifier is its filter.

If ordinary people can't afford an air purifier, they can buy some defective filter cartridges to use.

Used filter cartridges are collected in special recycling bins.

The couple would go to the trash can in the middle of the night to collect discarded filter cartridges.

Take it back, purify it, and then take it to the market to sell.

"Isn't it said that all buying and selling is controlled by the government? Don't they manage private transactions in the market?"

Shi Jinwei couldn't help but ask again.
