The sound of the broadcast in his ears ended, the train immediately started, the carriage was empty, and Lin Tuo could see the road map on one side when he raised his head...... The design is similar to the subway on Earth, but it is extraordinarily long.

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

"Sanjiang Station...... Old geothermal ...... Sewer...... The name of the "four-way ......" is strange, and it is not clear whether it is not good to listen to in the first place, or it is a pot of linguistic translation......

At the end, the style of painting changed, and the name changed to "Slime Station", "Kakashi Station" and the like, which made Lin Tuo look surprised.

I tried to look for it, there are no books in the carriage, only some advertisements, most of them are mainly sales, strolling through the various carriages, you can see some passengers scattered.

Almost all of them look the same:

Slumped in his seat, eyes closed, drowsy.

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

Leaned over and glanced at it, it's not a smart phone, it's more similar to an old-fashioned telephone, with a tweeting kind, the screen is very small, there are buttons, there is a bulge on the back, and there are still some differences from the feature phones on the earth.

There were few people in the carriage, and Lin Tuo didn't need to rob it, so he didn't need to steal it, and after a few glances, he judged a rough idea.

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

"Next up is the ad break...... The fruit and vegetable area of the South Outer Ring is on sale, and the 95% discount is ...... "This is an advertisement."

“…… Haririn, the leader of the New Party, launched the "Plan for Improving the People's Livelihood Environment in the Outer Ring" for the third time...... believes that fiscal ...... should be liberalized" - news.

……

The train was whistling, Lin Tuo eavesdropped for a while, mainly the news broadcast, combined with the conversations of the people in front of him, he really analyzed some information for him.

But there is still a lack of details, and it is difficult to judge.

"I still have to find a way to get to know the city quickly."

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

Originally, it was dark outside the window, and I could only rely on the street lighting of each station, and the reflection of the glass inside the car, so I couldn't see what was going on outside.

But at this moment, there was suddenly more pale white light outside the car window, as if the sky had suddenly stepped from late night to early morning.

"Passengers: In one minute, the area will enter daylight ......"

In the carriage, the sound of the announcement also sounded suddenly.

Inside the carriage, many passengers opened their eyes and looked out of the window expectantly, as if they were accustomed to this.

Lin Tuo also saw the outside scenery clearly with the help of the faint light, one side is composed of dense gray standard buildings, mainly residential houses and factories.

There are some small shops and landmarks in between, and on the other side, there are fields.

It is not tiled, but triangular, and the slopes on both sides are full of plants.

As the "one-minute countdown" ended, the ceiling of the space suddenly lit up, and there was a blue sky like water, and there were white clouds fluttering, and a huge simulated sun suddenly illuminated the whole world.

"That's what it is...... A simulated ecology of a dungeon? ”

Lin Tuo was a little surprised, and the passengers in the carriage were also enjoying the sunshine to the fullest.

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

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

Many well-dressed and listless social animals ran out of the building that looked like the 90s of the earth, some carrying the breakfast they had just bought.

Go to another nearby station and take the next train.

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

……

……

When Lin Tuo blended into the train again, he found that there was a lot of crowding around.

The advertisements in the carriage have also changed from sales to more abundant, and the most of them is a virtual game called "The Third Continent", which claims to have tens of millions of people online, and I don't know whether it's true or not.

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

Others sit on the subway and put it on their heads, then close their eyes, and then the slightest aether fluctuation is transmitted.

Lin Tuo speculated that this may have something to do with the so-called "virtual technology".

and resisted the urge to grab one under the study...... 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 of the major stations would have clocks with additional "morning and dusk" times, and by observation, he found that there were only six hours of daylight in the area outside the Eighth Ring Road.

The daylight from the 8th to the 4th Ring Road is eight hours.

As for the inner part of the Third Ring Road, there are twelve hours.

This seems to be a trade-off in the use of energy, after all, the simulated sky must also consume a lot of energy, but does this not reveal a clear hierarchy?

Not only that, after entering the Eighth Ring Road, the buildings outside are also significantly better, and there is already the style of the earth for about 10 years, office buildings, shopping malls, colleges and universities......

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

This made Lin Tuo curious about the situation within the Third Ring Road, but he didn't choose to look at it after all, but simply walked off the subway after seeing a certain building through the window.

……

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

"National Library ......" silently recited five big words, Lin Tuo blinked, and immediately stepped into it:

"This should help me get to know this place quickly."

……

The earth froze, and wood and all the fibers became luxuries.

Along with it, paper-printed books are also extraordinarily expensive.

Naturally, there are paper books in the library, but there are not many of them, and the main thing open to the public is the "electronic reading room".

However, for Lin Tuo, this is more efficient.

Without much effort to figure out how the reading machine operated, Lin Tuo found a corner where no one was around, and began to retrieve and consult the information he needed.

The strong mental power is reflected in the reading speed, which is much faster.

An hour later.

The ghostly Lin Tuo silently walked out of the "National Library", wandering the streets somewhat ramblingly, and finally had a certain understanding of this world:

According to the calendar, 213 years have passed since the "Great Ice Age", the whole world has passed the initial era of "resource scarcity", and the take-off of virtual technology has lasted for 55 years.

The ruling organization is still the "Supreme Council" but the word "union" has been removed, and the original four countries have completed the integration and unification, and the languages have been retained, but the official first language is the original lingua franca of the southern continent.

The original four royal families existed in the form of parties and took turns in power.

The whole society rests on this large city, and the periphery is the means of production...... The underground planting bases, factory areas, mining areas, etc. are located in the suburbs.

Fifteen metro loops cut the shelter into three parts.

Rings 1 to 3 are the "inner rings", where government agencies, research institutes, large companies, and some venues are located, which belongs to the "elite area".

Rings 4 to 8 are the "Central Rings", where most of the companies, schools, hospitals, and entertainment venues are located, and it is also home to the largest "middle class" in the whole society.

As for the "outer ring", it refers to the area from the 8th to the 15th ring road, which is at the bottom of the social structure of the shelter, where the largest number of people are concentrated and enjoy the fewest 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 déjà vu......

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

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

This allows you to enter the "virtual world...... At first, virtual technology was only used to solve psychological problems...... After all, in the early days, the dungeon was in dire straits, unable to support too many people, and could not provide enough jobs.

Therefore, some mages and scholars have tried to use this technology to set up a virtual space for the public, so that people can work and play in it, reduce consumption, solve psychological problems, and reduce social conflicts.

Later, the technology tree of the whole society was distorted because of this...... As a result, there was a boom in virtual networks, not just for entertainment, but also for a lot of work moved in.

This is also the reason why there are not many physical entertainment venues along the way, and mobile phones are also in the feature phone stage.

As for the "abnormal and extraordinary phenomenon", through the search of news newspapers and periodicals, Lin Tuo also found clues.

"The only news worth noting recently and suspected of involving supernatural powers is 'Internet Lai Syndrome'...... According to the news, the 'Internet Lai Syndrome' is closely related to the most popular game "The Third Continent" recently......"

Lin Tuo walked slowly.

"If the problem is in the virtual space, then the abnormal monitoring results of the instrument can also explain it...... Because the virtual space is not physical, it cannot be accurately locked. ”

As he walked, 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 more sure, you have to get a 'brain computer'...... Well, it is best to have a supporting operating environment. ”

This made Lin Tuo frown, the brain and computer are all bound, and they can't be used by others, as for the purchase...... It's too much trouble, and it's ...... He has no money.

"It would be nice if I could prostitute one for nothing." Lin Tuo couldn't help but think.

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

"This Internet café has opened a new virtual game area, and the first seven days on the machine will be 50% off!"

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

……

At the mouth of the alley, Lin Tuo stuffed his hands in his pockets, read them carefully, and then looked up at the alternately flashing neon lights at the door of the Internet café and blinked.
