Why is there a section of railroad track in this section of abandoned sewer, because it is in the humid air all year round, and has not been properly maintained and repaired, so this section of rail has long been rusted and black, and it is impossible to tell if it were not for the turtledove just tripped over it, and the insects may not be able to find it until now.

"Where did the rails come from?"

Turtledove, whose toe was almost kicked off, looked back angrily, his eyesight was not as exaggerated as that of the worm, and when he heard the worm say that it was a section of railroad track that tripped over him just now, the turtledove turned around and bent down to check, and gently wiped a handful of his fingers on the rails, all rust.

"I don't know where to go," the little worm also came over and squatted down to examine the railroad track carefully, "It must have been a long, long time ago, but isn't this a sewer, how can there be such a section of railroad in the sewer?" ”

No longer looking at the railroad tracks on the ground, the worm stood up and looked around, and she found that although it was still an underground passage, it was much more open than before, and the diameter of the passage had doubled from five or six meters to a little more than ten meters, and it tended to become wider and wider as it went.

So where does this "sewer" ultimately lead?

"Let's take a look."

The little insect said to go, and the turtledove behind hurriedly followed, and the two of them walked forward for almost a few minutes, and the diameter of the passage had become more than ten meters at this time, which seemed spacious and abnormal, that is, there were very many debris in the passage, there were almost rotten wooden boxes and broken bricks and tiles, and some other things.

Why do you want to take these wooden chests out of their own way, because they don't seem to fit in with the environment here, and they shouldn't be here.

Originally, the manual work of opening the box required turtledoves to do it, but these wooden boxes were already rotten to the point that they could not be seen, and the little insect could break the wooden strips on the outside with a casual hand, and with the choking rancid smell, the little insect found that these boxes were actually filled with some puffed snacks with plastic packaging.

"What the hell?"

The worm really couldn't understand what it meant, why there were railroad tracks in the sewers, why there were spoiled puffed snacks in wooden boxes, what the hell was this place.

"Hey! There are a lot of vending machines here! ”

Not only has the worm been found here, but the turtle dove on the other side has also been discovered, and he has found more than the worm.

Hearing the turtledove calling, the little worm had to drop a bag of tomato-flavored fries in his hand, and walked towards the turtledove, and before he could get closer, the little worm noticed that the place where the turtledove was was clearly higher than where he was, and it turned out to be the platform.

Scanning the surroundings again, the little worm said that no wonder he felt that this place looked a little familiar, it was a railroad track and a platform or it was underground, this was clearly a waiting platform, a waiting platform for the underground railway.

The Underground Railroad is also known as the "Metro", and the Bugs have not only seen it in the New Empire, but also used it often.

……

Naturally, there is no subway in the mouse city where Turtledove grew up, so he doesn't know what those rails and the platform here represent for the time being, but people Turtledove doesn't care about these dispensable things at all, and his attention is all on the row of vending machines on the platform.

Of course, there is no way to use these vending machines, and the things they sell are not food, but turtledoves just like to see such things, even if they can't eat them, just looking at the outer packaging is enough.

To tell the truth, the turtledove did feel quite hungry, and since the sandstorm, the turtledove hadn't eaten much, at most he had drunk some water, and as for the food, he really hadn't eaten at all.

The belly is not full, but the sin is not less, and the turtledove can't help but complain about what happened to him recently.

"I can't eat any of these things."

Xiao Worm pointed to the vending machines in front of her, which were estimated to be older than the two of them combined, and even turned over them again, and said to the turtledove with a sincere face, as if she was really afraid that the turtledove would find something to eat from inside.

"I'm not a three-year-old child," the turtledove said to the worm's expression that he was very unhappy, "what can and can't be eaten, I still don't know this, but you, have you found anything over there?" ”

"None of the useful things have been found, but we at least know that this is a subway platform, as for the coverage of the subway, what is the place in front, this depends on whether we can find a stop sign or something, if we can find a stop sign, I believe there will be a lot of information we need at present."

What is the most important information that the little worm and the turtle dove need at the moment, naturally it is the subway route map, so that the little worm can decide where she and the turtle dove should go next according to the route map, and if there is no such thing, the two of them will easily get lost in the intricate subway line, and it will not be so easy to get out of it when the time comes.

"Subway? Stop? ”

The turtledove's two big eyes stared, waiting for the little worm's explanation, so the little worm spent a few minutes explaining to the turtledove what the subway is and the role of the subway.

……

"And such a thing?"

After listening to the latest round of popular science of the worm, the turtledove said that it was the first time he had heard such a high-tech thing as the "subway", but he didn't expect that the railway could be laid underground, and the turtledove had only seen a train running on the ground before, and never thought that the train could also run underground.

"You haven't taken the subway of the New Empire, that guy is really fast, even so, it still takes a lot of time to take the subway to go through several major cities of the New Empire, the New Empire is so big, if there is no subway to connect the cities with each other, it is very troublesome to go from this city to another city."

The turtledove smacked his lips, his understanding of the new empire was basically all obtained from the worm, as the so-called "seeing is believing, hearing is false", the turtledove who has not really lived in the new empire can't just rely on the worm's words and his own imagination to figure out the grandeur of the new empire, unless he goes there in person.

The two of them continued to walk along the railroad tracks under the platform, this place has been abandoned for I don't know how long, and there is no need to worry about whether this will be hit by the oncoming subway, but there are other accidents that cannot be avoided.
