Fang Shu grew up in the factory in the mountains with the factory director when he was a child, although he heard the factory director mention the company's affairs, but he has never been in contact with anyone in the company except the factory director. So he has no feelings for the company, and his own personality is the kind of person who doesn't care except for relatives and friends. He doesn't feel guilty about keeping it secret that Chida is a new type of person. He felt that this would not affect his ability to gather information on new types of people, but would be very helpful.

Fang Shu knew the details of Qida, plus his current situation. He was no longer wary of Qida, and the two quickly became good friends in the car. Qida informs Fang of the basics of conversation in the underworld, and then talks to him about the underworld.

After saying some of the things that are not there, Qida asked Fang Shu: "The people in the upper world and the people in the underground world are different in the frequency of heat released by the body, and we call this frequency the heat rate. There is such a detection device in the door that enters the tunnel, and only those who meet the heat rate of the underground person are qualified to open the door. But I didn't expect the door to open when you passed by there, what the hell is going on? ”

"Huh? Do you mean that my body has the same heat rate as an underground person? How is this possible, I grew up on the earth since I was a child. "Fang Shu is very puzzled.

Qida didn't look like he was lying, but he knew there must be something wrong with it: "What about your parents?" ”

"I haven't met them, and I've never heard from the factory manager. I have been following the factory director since I was a child, and he is my father. When Fang Shu mentioned the matter of his parents, he looked a little lonely. During the time of studying, when I saw that other parents cared about their children, but I didn't, I had mixed feelings.

"Sorry to mention your sadness." Qida felt Fang Shu's sadness, "Let's end this topic, there is no need to think about the past." ”

"It's okay, after so many years, it's not so sad anymore." Fang Shu waved his hand and continued, "But I do want to know who my parents really are. ”

"You'll always know."

The two chatted and chatted that the train had stopped, and the mustachioed man slowly walked over and asked, "The train has arrived." ”

"Let's go."

After getting out of the car, the two stood on a huge high platform. At a glance, he couldn't see the edge, and the most conspicuous thing in his field of vision was a huge column, which reminded Fang Shu of the giant foot of the 10,000-year-old giant tortoise in the sky that he had seen before. Just one large cylinder gave Fangshu an incomparably small feeling, but there were four such pillars in the field of vision. These four columns are holding a blue sky and stepping on a bustling and beautiful city. There were a lot of flying objects in the sky above the city, and it was too far away for Fang Shu to see what they were.

Fang Shu pointed to the sky and asked, "Isn't this underground?" Where did the sky come from. ”

"It's a projection technology, and that sun is artificial. However, this artificial sun is nowhere near as powerful as the real solar action. ”

"It's a simulation of the whole sky." Fang Shu sighed, "What are the functions of those four big cylinders?" ”

"To prevent collapse. I'm not familiar with it, but every underworld has pillars like this, and they should work like this. I've heard before that there were no such pillars in the Underworld, and the expansion of territory was greatly limited. Someone found a special material that does not have a high melting point, but is very strong and durable, and it is difficult to corrode, and this material is the material of the large cylinder. ”

"It's a spectacle for people who live in the earthly world." People have a special sense of awe in the huge east and west, but when they learn about the role of this thing, they still have a sense of admiration.

Qida was already surprised: "Nothing remarkable, let's go and have a look below." Fang Shu looked around the high platform and didn't find any way to go down, he scratched his head and asked, "Is this going to jump?" ”

Qida smiled awkwardly and said, "Don't worry, something will come later." It wasn't long before Fang Shu saw a flying object in the air flying towards them. It was a capsule-shaped machine, and Fangshu felt like it was supposed to be some kind of vehicle.

"Sharing capsule car, I just called one on my mobile phone."

"Isn't this a place for big people to get off the bus, I thought there was a special car." Although he had never seen a capsule car, Fang Shu still felt that the car should be more special. Qida felt a little funny: "Who said that all the big guys should have a special car, and you should know very well whether you are a big guy or not." ”

"That's right, you're not a big deal." Seeing Qida mocking himself, Fang Shu also fought back unceremoniously.

"I don't care about any of that, get in the car." Chida said and knocked on the car door and sat in the driver's seat.

A small capsule car can fit two people, one of whom can drive. Fang Shu sat next to Qida and asked, "How does this thing work, and where are we going now?" ”

"I remember you said you wanted to gather information about the underworld, so you should take a walk around this area. People in the Tian District all speak Chinese, as long as you pay attention to what I told you before, you will definitely not feel that you are anything different. I've got something on my side that I'm going to have to deal with alone, and we'll be meeting up then. As for the way to operate the capsule car, it is very simple, self-driving is on the line, or it can be operated through this joystick. Qida said with some seriousness.

He sensed that there was a change in Chida, so he asked, "Where are you going, how long will it take, and where will we meet at the restaurant?" ”

"I need to look up some information, and one of the libraries in the Sky District is the most comprehensive library we recognize. Because of the permission problem, you can't find anything even when you go in. I'd like to see if I can find something, so for the sake of efficiency, you'll go on a field trip here. ”

Fang Shu nodded, and Qida parked the car in front of a restaurant and told him to get out of the car, and told him that whoever finished the business first would be waiting for the other party here.

After Fang Shu got out of the car, he began to take out his mobile phone and shoot around. Along the way, he saw various styles of buildings, including high-tech mansions, quaint and old houses, and strangely shaped buildings. The convergence of these buildings makes it a novelty for Alchem to walk around the city. He tried his best to suppress his impulse to hope, silently thinking in his heart that he was just a photographer, and he was just taking pictures of the street scene.
