Early the next morning, Fast found Ou Xiaolu and led him into a nearby subway.

"When you enter the underground world of Xinxiang, you must go through the subway, there is no way to go down by other methods, there may have been vents or something before, but now the vents are gone, even if you want to dig it directly, it is impossible."

"Teleportation or something?" Ou Xiaolu asked with some curiosity.

Fast laughed when he heard this, "Are you kidding?" Where can anyone use teleportation now, not even the president of the Wizards' Guild can't do it. ”

For this, Ou Xiaolu didn't want to explain that he had an avatar under him who could use teleportation.

The two walked into the subway station with Arrow like this, speaking of which Fast is also a very capable existence, and I don't know what method he used to make the passengers in the subway ignore Arrow, a giant tiger taller than a baby elephant.

After the three of them got on the train, Fast said: "Don't look at it, they haven't seen anything in the subway station, let alone the giant tiger, even if it's a demon, they've seen it." ”

As Fast spoke, a demon with a body of fire walked not far away.

However, Ou Xiaolu could see at a glance that this demon was the kind of existence dressed as an ordinary person, and the flames on his body were just cold flames, and they had no effect at all.

After they had been on the subway for about ten minutes, Fast suddenly said, "It's almost time to get off." ”

"Ah, get out of the car?" Ou Xiaolu glanced at the situation around him, and the speed of the car did not decrease at all.

"Don't worry, if you can't get off the train, why will I ask you to sit in this carriage." Fast said as he reached the door.

At about this time, the door suddenly opened, and Ou Xiaolu found that a black subway appeared on the opposite side at some point, and the speed between the two subways was the same, as long as you had a little guts, you could step on the opposite subway with one step.

Seeing that Ou Xiaolu had the intention of being in a daze there, Fast jumped over directly.

Then he beckoned and said, "Come quickly, there will only be three minutes between the two cars." ”

Ou Xiaolu was a little speechless about the thoughts of those people in the underground world, in fact, with the thoughts of those people, there was no need to be so troublesome at all, just open a passage to let people come and go in the underground world.

But if you want to hide yourself, then hide it, and everyone knows about it, then it's very boring.

While complaining about this, Ou Xiaolu took A Luo into the black subway.

After walking here, Ou Xiaolu found that the black subway floor was not made of steel, but a living one.

Fast pointed to the chair and said, "Just sit, let me tell you, don't look at the thousands of passages down, but it's still the most convenient to take the subway." ”

"When you come down in other places, you have to go through all kinds of passages, and there are also some forces' territories, and after you pass, you either kill the past or pay the money, how can it be convenient to take the subway."

Ou Xiaolu was silent, Tie Zhongxiao didn't follow him at all at this time, he was staying in the guild, as long as Ou Xiaolu found a suitable door, he could be dragged out.

Seeing that Ou Xiaolu didn't react, and there was no one else behind him, Fast was a little disappointed, he thought he could let Ou Xiaolu bring some more people over.

At this time, Fast talked about the place he was about to go.

However, Ou Xiaolu was not very interested there, but Fast was talking about himself there, and Ou Xiaolu did not listen.

This situation made Fast a little depressed, and he was still thinking about how to lead the conversation to something.

But Ou Xiaolu didn't say anything like this, so how could he guide the topic.

Even if he could keep talking, he wouldn't be able to quietly lead the conversation to what he wanted to say.

At this moment, Ou Xiaolu suddenly stood up, pointed out the window and asked, "Where is that?" ”

Seeing that Ou Xiao Luken communicated with him, Fast was also excited, and he was about to look out the window, but saw Arrow also stand up, walked to the window and stared over there, as if there was something good over there.

Fast looked out the window with some confusion, but saw nothing, he was about to ask Ou Xiaolu what he saw, but found that Ou Xiaolu and Ah Luo had gone to the side to communicate.

Fast, who had a ghost in his heart, was a little uneasy, and he wasn't sure if Ou Xiaolu had discovered something.

In fact, he didn't know at all, just now Ou Xiaolu received a daily task, there were some good quality herbs there, if he was willing to stop and collect herbs, he could get a pretty good prescription.

It's just that Ou Xiaolu doesn't have talents in pharmaceuticals, so in the end he gave up this task.

However, Ou Xiaolu never thought that his unintentional behavior made Fast think too much.

The three of them quietly sat on the black subway and entered a passage.

Along the way, Fast didn't say anything more.

After getting out of the car, Fast led the way in front and led Ou Xiaolu and Arrow into an underground space.

The underground space in front of me should be transformed from an air-raid shelter, and the whole space is not very large, and it seems that it covers an area of three or five acres.

On the walls around the space, there are small caves that have been barricaded with worn cloth, leather, or metal.

It can be seen that the caves are used for people, and the space outside the caves is used for communication.

After bringing Ou Xiaolu and them here, Fast said directly: "We are going to prepare to take the fast track, if you have anything to buy, you can buy it here, you can buy all the things produced on this floor here." ”

Ou Xiaolu glanced at it and couldn't help but sigh, he found that the residents who came and went here didn't seem to be all humans.

Some of the inhabitants look like a mix of humans and rats, and seem to be rat people who have appeared in fantasy experiences.

Perhaps seeing the doubts in Ou Xiaolu's heart, Fast finally spoke.

"Those are not rat people, but clones, they are cloned from the genes of humans and rats, they are infertile, but they can live for about thirty years, and they consume little, they are good at mining and pathfinding, and if you need them, there are a lot of them for sale at the next two stations."

"Is there a cloning technology in place?" Ou Xiaolu thought that he might grab a vein, so he couldn't help but ask more.

"No, and if you don't want to offend someone, it's best not to mention it." Fast said to Ou Xiaolu very seriously.
