If there are other incarnated beings who have come here as well, then they must know about this world, so it seems more efficient to ask directly.

But I can't do that, it's a very simple reason, let's say I'm going to buy something, and it's about my life, and at the same time there's another person going to buy it, and it's also about his life, so what if I ask him about something like this at this time?

There is only one consequence, and that is to be eliminated by him by all means. Without knowing what such a thing is, or knowing how many there are, no one is going to joke with their lives, and the same applies here.

Looks like I've got one more thing to do now, to track down the dark red robot and find a way to take the notes away without him noticing, if that doesn't work......

I didn't get too close, I spotted it by about three shelves away, but the dark red robot didn't notice me because it was far away.

I slowed down, tried not to make too much noise, and quietly followed it. I saw it go all the way out of the library door and stop at the cogwheel square. It lowered its head, as if thinking about something, and for only three or four seconds, it walked towards an alley.

In terms of direction, the alley should lead to the north. I followed it all the way, always keeping a distance of ten meters from it, even when I was turning. Even so, it was almost discovered halfway through, and the anti-reconnaissance ability shown by this dark red robot is not what a robot should have at all, and it is clearly a reaction that only humans can make. Almost every minute or so it walked around, it would stand still and scan its surroundings to make sure no one was following it before continuing its journey.

If you don't believe that this guy is not a weird ghost, this behavior at least means that this dark red guy is very different from those common robots.

I followed it so carefully, and the more I followed it, the more strange it became. It has been walking north since it left the city library, and has been walking in a straight line except for two turns in the meantime, and picking out the small alleys where no one is around. And it's all the way north, it's almost to the edge of the city, and before that there is no construction site, there is no one else except some construction robots, and there is no place like a house, what does it want to do here?

Well? Is it going to turn?

Just when I was wondering, the road ahead ushered in a right turn, and as I watched it turn, I followed suit. I can't see it when turning, so I can only roughly calculate its speed and keep up with it at about the same speed.

But when I turned the corner, it was not a road, but a dead end, with the walls of a half-finished building in front of me, and there were no forks on either side, and the same building frame, and the height that neither machines nor humans could climb up, at least not without tools.

But the dark red robot I've been tracking has just vanished from the world.

I walked briskly to the end of the road, looking around, but found no place to hide, no way to hide. Could it be that this guy can teleport? Why do you disappear after walking into a dead end? This makes this dark red robot shrouded in another layer of mystery.

I had no choice but to go back the way I came, confused, but what I didn't know was that shortly after I turned around, a pair of dark red eyes were staring at my back.

Walking briskly, I hurried back, so focused on the crimson robot that I didn't notice that I had followed it to the edge of the underground city, and I didn't see how much power I had left.

I looked at the big clock tower in the distance, and the hands had already crossed the scale a little. What a miscalculation, I hope I can get back. Actually, if I don't make it back, I don't know what the consequences will be, but my gut tells me that it won't be a good thing.

For Oude, I can clearly feel that my impression of him is incomplete, in my opinion now, he is a person who likes machinery and loves his sister deeply, and generally speaking, he still has a good impression. But deep down, there is always a strange feeling that I can't tell what it is.

Ouya gave me a different feeling, when I first saw her, I knew her name, and even had some impressions of her. She should be the kind of girl who is the same as the outside, with an angelic appearance and an innocent and lovely personality, I believe that most people's first feeling of her is a good impression. But my first feeling for her was guilt, as if I had done something to hurt her, but I couldn't remember what it was.

An hour passed quickly, and it was really not an easy thing to live in this place where there was no day and night, and it was indeed a paradise for those who did not need to think about the time, and who got carried away with singing and dancing every day. But this is not the case for us, without the supervision of the numbers on the display, I am afraid that a lot of things will be delayed. Luckily, I rushed back just before two o'clock.

"J7, it's just in time to come back, I'll replace the battery for you, it's time to complete the task." Oude came up behind me, replaced the battery, patted me on the shoulder, then picked up the bulging package around him and walked out.

Ouya followed behind Oude, bowing her head slightly, looking at her red lips that read, and she didn't seem to particularly want to go. The main task of their group in Tisball is to repair and maintain machinery for the military, which must be a small amount of work, as can be seen from the need to stay here for three days, presumably this afternoon will be spent in the military factory, which is really not an interesting thing for a little girl.

Leaving the gate of the temporary residence, a small flying ship stopped at the door, and Oude stepped forward to explain a few words to the driver, and we sat down together.

The flying ship is powered by steam, so it doesn't fly fast, and with a heavy machine like me inside, it's even slower. It took us about forty minutes before we stopped in front of a tower that jutted out into the rock on top of the underground city.

I also know this building, and in my last experience, it was from here that I entered the ground Tisbor, which is also one of the three passages to the ground.

"Hey, Ode, what is this place for, isn't the military factory on the ground?" Ouya poked Oude's side waist, causing Oude to grin for a while, and almost laughed.

"Ahem, don't make trouble", Oude coughed twice, pretending to be serious, as if he wanted to relieve his embarrassment, Zhengse said, "This is actually part of the military factory, responsible for manufacturing some military items, and the difference from the ground, most of the underground military factories produce some open items, such as mechanical arms and mechanical legs, which can be bought here, so the underground military factory is allowed to enter by ordinary people, and there are also some merchants who will order original products here, and then process and sell them." ”

"The reason why I went up from this side of the passage today is mainly because this side is closer to the military factory on the ground, and there are fewer people, and generally no one will go to the ground at this time period, after all, the temperature is too unbearable. Of course, there is another reason......" Speaking of this, the corners of Oude's mouth couldn't help but grin a little, and then his expression quickly changed from a smile to a snickering like an idiot, and it could be seen from his sight that he must have become interested in some mechanical products again.

Ouya patted her forehead, looking a little helpless about Oude's current appearance, with an expression that I didn't recognize him.

"Hello respected mechanic, may God bless you." A soldier stepped forward and gave Ode a military salute, who nodded and followed him towards the inside of the tower.

After a few checks, we slowly moved along the platform elevator to the ground, and when the elevator was about to arrive, the soldiers did not forget to remind us to wear goggles, because the strong sunlight is easy to hurt our eyes.

When he got to the ground, Ou De didn't dare to stay for a moment, and pulled Ou Ya to walk quickly in the direction of the military factory, and it was not even a minute before he came up, and he could see that the foreheads of the two of them were already covered with sweat, which showed how high the temperature was now.

In the midst of Ouya's complaints, we came to the real gate of the military factory, and as I remember, I was stopped when we reached the second checkpoint, the difference is that this time Oude and the guards had a hard time talking about it, and of course in the end they couldn't let me enter the inside of the military factory.

"Here's for you, hand it to the guards when you go in and out, and they'll let you in." Oude handed me a cog-shaped token, and I nodded and took it.

Watching the figure of Ouya waving her little hand at me fade away, I also turned around and left here.

Oude meant to let me move freely on the ground and wait until the sun went down to come back to them, but what could I do?

Because this experience was different from the last time, I had already turned around Tisball when I first arrived here, and I didn't find any useful clues. But now I can't go back to the underground city, and I'm a little overwhelmed.

At this moment, something red seemed to flash in my peripheral vision, and I subconsciously looked at it, it was a red figure, or a dark red robot, it was walking towards a narrow alley, and disappeared into the depths of the alley in three or two steps.

It's a narrow road, and I won't let you run away this time. With that in mind, I quickly followed.
