The announcement in the ears ended, and the train started running immediately. The carriage was empty. Lin Tuo raised his head and could see the road map on one side... The design was similar to the subway on the earth, but it was extraordinarily long.

Lin Tuo walked along the empty carriage and read the route name with interest:

"Sanjiang Station... the old hot mouth... the sewer... the four-way link..." The name is strange, and it is not clear whether it is not good at first or a pot translated by Tongyu...

At the end, the style of painting changed, and the name changed to "Slimes Station", "Kakashi Station" and so on, which made Lin Tuo amazed.

I tried to find it. There were no books in the carriages, only some advertisements. Most of them were mainly for sale. Walking through the carriages, you could see some passengers scattered.

Almost all looks like:

He collapsed on the seat, closed his eyes, drowsy.

Every few minutes, the car would stop, and gradually there were more people. Lin Tuo quietly observed and found that some people would fetch something similar to a mobile phone from their pocket and plug in headphones to pass the time.

I leaned over and glanced at it. It is not a smart phone, but more similar to an old-fashioned phone with a chirp. The screen is small, there are buttons, and the back is raised, which is somewhat different from the functional phones on the earth.

There were few people in the carriage, and Lin Tuo didn't use it to grab or steal. He looked at it and judged it.

Can make calls, send and receive text messages, the function is simple, there should be a broadcast function, with "inhuman" hearing, he can even hear the sound leaking from the headset:

"Next is advertising time... The South Outer Ring Fruit and Vegetable Zone is on sale, and a 5% discount is on sale..." This is an advertisement.

"...The New Party leader Harilin launched the "Plan for Improving the People's Livelihood and Environment in the Outer Ring" for the third time... he believes that finances should be liberalized..."-News.

...

As the train roared, Lin Tuo overheared for a while, mainly news reports, combined with the conversations of those people before, really analyzed some information for him.

However, details are still lacking and it is not easy to judge.

"We still have to find a way to quickly understand the city."

While thinking about it, the scene outside the subway window suddenly changed!

Originally, it was all dark outside the windows, so I could only rely on the streetlights at various stations and the reflections of the glass inside the car, so I couldn't see what was outside.

But at this moment, some pale light suddenly appeared outside the car window, as if the sky suddenly entered the early morning from late night.

"Dear passengers: In one minute, this area will enter daylight..."

In the carriage, an announcement sounded abruptly.

In the carriage, many passengers opened their eyes and looked out the window expectantly, as if they were used to it.

Lin Tuo also took advantage of the faint light to see the outside scenery clearly. One side is composed of dense gray standard buildings, mainly residential houses and factories.

Interspersed with some small shops and landmark buildings, the other side is actually a field.

It is not flat, but triangular, with plants growing on both sides of the slope.

With the end of the "one minute countdown", the ceiling of the space suddenly lit up. It was a blue water sky with white clouds fluttering. A huge simulated sun suddenly illuminated the whole world.

"This is... the simulated ecology of the dungeon?"

Lin Tuo was a little surprised, and the passengers in the carriage also enjoyed the sun to their heart's content.

At this time the train arrived at the terminal station, Lin Tuo got up and got off the train with the flow of people. The buildings, communities, streets, people walking or riding bicycles in front of him... are clearly distinguishable.

As we enter the "day", the entire outer ring area seems to be lively.

Many neatly dressed, listless social animals ran out in groups from the tube building that looked like the earth in the nineties, and some even carried the breakfast they had just bought.

Go to another platform nearby and take the next train.

Lin Tuo glanced at the sign and confirmed that the train was heading to "Central."

...

...

When Lin Tuo got into the train again, he found a lot of crowds around him.

The advertisements in the carriages have also become richer from the sales of buildings, the most of which is a virtual game called "The Third Continent", which claims to be online with tens of millions of people, and it is not true or false.

The "equipment" of the young people in the carriage has also become richer. In addition to the functional machine, Lin Tuo noticed that many people have something like a "headband" hanging around their necks.

Some people put it on their heads while sitting on the subway, then close their eyes, and then, there is a slight wave of ether transmitted.

Lin Tuo speculated that this might be related to the so-called "virtual technology".

And resisted the urge to grab one for research... and as the train headed towards Central, he was surprised to find that the "daylight" of the different loops seemed to be out of sync.

Some big stations will fix the clocks, which will additionally display the "dawn and twilight" time. Through observation, he found that there are only six hours of daylight in the area outside the Eighth Ring.

There are eight hours of daylight from the eighth ring to the fourth ring.

As for the third ring road, there are twelve hours.

This seems to be a choice of energy use. After all, simulating the sky must consume a lot of energy, but doesn't this reveal a distinct class?

Not only that, after entering the Eighth Ring Road, the buildings outside are obviously much better, and they have been around the world for about a decade, office buildings, shopping malls, colleges and universities...

Although it still looks crowded, it is obviously much better than outside the Eighth Ring Road.

This made Lin Tuo wonder about the situation within the third ring road, but he did not choose to look at it after all, but simply stepped off the subway after seeing a certain building through the window.

...

Ten minutes later, Lin Tuo appeared outside a building that looked brilliant in the sun.

"National Library..." Lin Tuo blinked and stepped into it as he read five characters in silence:

"This place should help me understand this place quickly."

...

The earth is frozen, and wood and all fibers have become luxury items.

In addition, paper-printed books are extremely expensive.

Naturally, there are paper books in the library, but not many. The main one open to citizens is the "electronic reading room."

But for Lin Tuo, this is more efficient.

Without much effort to figure out the operating method of the reading machine, Lin Tuo found a corner where no one was left, and began to retrieve and consult the required information.

Strong mental power is reflected in a much faster reading speed.

after an hour.

The ghostly Lin Tuo walked out of the "National Library" silently, wandering in the streets some boundlessly, and finally got a certain understanding of the world:

According to calendar calculations, 213 years have passed since the "Great Ice Age" in this era. The entire world has passed the initial era of "resource scarcity", and the take-off of virtual technology has continued for 55 years.

The ruling organization is still the "Supreme Committee", but the word "united" has been dropped. The four countries have been integrated and unified, and the languages ​​have been retained. However, the official first language is the original southern mainland lingua.

The original four royal houses existed in the form of parties, taking turns in power.

The entire society relies on this large-scale city, surrounded by various means of production... Underground planting bases, factories, mining areas, etc. are all located in the suburbs.

Fifteen loops divided by subways cut the entire shelter into roughly three parts.

Rings 1 to 3 are the "inner ring". Government agencies, research institutions, large companies, and some venues are all located here and belong to the "elite zone".

The 4th to 8th ring is the "Middle Ring". Most companies, schools, hospitals, and entertainment venues are located in this part. Here is also the largest "middle class" in the entire society.

As for the "outer ring", it refers to the area from the 8th ring to the 15th ring, which is at the bottom of the social structure of the shelter. It gathers the largest population and enjoys the least resources including light...

The biggest wish of most ordinary people is to buy a house in "Central" and settle down...

As for the "inner ring"... that's too far away.

This gave Lin Tuo a strong sense of sight...

As for the "headband" seen on the subway, the official name is: "brainwave connection machine".

Abbreviation: "brain computer" or "virtual headwear".

You can use this to enter the "virtual world"...In the beginning, virtual technology was just to solve psychological problems...After all, the early dungeons were distressed in resources and could not support too many people or provide enough jobs.

Therefore, some masters and scholars try to use this technology, assuming a virtual space, and providing it to citizens, allowing people to enter it for work and entertainment, reduce consumption, solve psychological problems, and reduce social conflicts.

Later, the science and technology tree of the entire society was a bit crooked...and it caused the prosperity of the virtual network. Not only entertainment, but many jobs were moved internally.

This is also the reason why we haven't seen many physical entertainment venues along the way, and mobile phones are also in the functional stage.

As for the "abnormal phenomena", Lin Tuo also found clues through searching news newspapers.

"The only thing that is worth noting recently is that the only news that is suspected of involving extraordinary powers is the "Net Lai Syndrome"... and according to the news, the "Net Lai Syndrome" is closely related to the most popular game "The Third Continent"..."

Lin Tuo walked slowly.

"If the problem lies in the virtual space, the abnormal monitoring results of the instrument can also explain...because the virtual space is not a physical entity, it cannot be accurately locked."

During the walk, the buildings around Lin Tuo were getting older and older, and there seemed to be a school in front of him.

"So, if you want to be sure, you have to get a'brain computer'... Well, it's better to have a supporting operating environment."

This made Lin Tuo frown. The brains and computers were all bound and could not be used by others. As for the purchase... it was too troublesome, and... he had no money.

"It would be great if I could prostitute for nothing." Lin Tuo couldn't help thinking.

Then in the next second, his footsteps stopped and his eyes fell on the glass wall of an Internet cafe in the alley ahead, where two "slogans" were pasted:

"This Internet cafe has a new virtual gaming area, and the first seven days are 50% off!"

"The "King of War" challenge is in full swing, and the first person who clears the level or has the highest score will be rewarded with the virtual game warehouse for free for half a year!!"

...

At the entrance of the alley, Lin Tuo put his hands in his pockets, read it twice, then looked up at the neon lights that flashed alternately at the entrance of the Internet cafe and blinked.
