Xia Qing said: "That kind of light was just a sphere at first, but there was no light source, don't you think it's strange?" ”

Gao Chao shrugged his shoulders: "It's strange, but I can't imagine what this has to do with that kind of light." ”

Xia Qing thought about it again: "I'm not sure yet, but if it can become a circular light, it can also make the space bigger, or it can transfer the space, I think it's very likely to be...... Black hole. ”

"Black holes?" Gao Chao and the fat man shouted at the same time.

The fat man pouted: "Professor Xia, I don't read much, don't lie to me, shouldn't a black hole be a hole?" ”

Gao Chao also said: "Isn't a black hole a substance in the universe?" How can it be a black hole? ”

Xia Qing seemed very patient: "First of all, a black hole is not a hole, but the black hole we observe cannot reflect light, so it looks like a black hole, so it will be called so." ”

Gao Chao couldn't help but say: "But even if it's not a hole, how can it be a ball?" And it's a glowing ball. ”

Xia Qing said: "How can I explain this, the mass of the black hole is very large, so big that it has no friends, so its gravitational pull is also very strong, it can even distort light and space, and time, so some people boldly speculate that people can use this characteristic of black holes to travel through time and space, from one point to another very distant point, and it is very fast, close to the speed of light to travel through the past." ”

The fat man pouted, "But what does this have to do with whether it is a ball of light or not?" ”

Xia Qing said angrily: "Don't speak, I haven't finished yet." ”

The fat man stuck out his tongue, and Xia Qing continued: "Assuming I have a piece of paper in my hand, what is the closest and fastest route from one end to the other?" ”

The fat man replied: "It's a straight line, and there is a straight line between two points." ”

Xia Qing nodded: "Yes, but if you want to be faster, you can fold this piece of paper and overlap these two points, in this way, will these two points be pasted together, is this faster than a straight line?" ”

The fat man thought for a moment: "Are you playing tricks?" ”

Xia Qing ignored him and continued: "If I use a pen to poke a hole in the place where these two points are, what will you see?" ”

The fat man replied again: "It's a hole, a round hole." ”

Xia Qing patted the fat man on the shoulder: "Smart, that's right, then you can use your imagination, if you look at this hole in three-dimensional space is circular, then look at this circular hole in three-dimensional space in four-dimensional space, what will it be?" ”

This time, the fat man touched his chin and thought for a while without an answer, but Gao Chao thought about it: "Is it a ball?" ”

Xia Qing snapped his fingers: "That's right, it's a ball, that's what I said, why a black hole is a ball." ”

Gao Chao and the fat man finally got a rough idea.

"Could it be ......" Gao Chao pondered: "Could it be that the ball of light just now is a black hole, but...... But how does a black hole happen here? Also, why is it in a coffin? And where exactly are we now? ”

Xia Qing pondered for a while: "Do you remember?" I've done some research on the words on these coffins before, and I've found that the words on them are oracle bones, but they are much more than the oracle bones we've found, but I still recognize a few of them, although they are just words, but they probably mean 'leave', or ' I saw it two or three times on the coffin board on one side, and I couldn't figure out what these two words represented here, but now that I think about it, I seem to suddenly understand. ”

The fat man couldn't help but say, "What do you understand?" ”

Xia Qing said: "Maybe these coffins are not real coffins, they are machines that travel through time and space. ”

When he said this, Gao Chao's mouth grinned: "What did you say?" A machine that travels through time? ”

The fat man laughed: "A time-traveling machine? Haha, how do I feel like I'm back in my kids? ”

Gao Chao sighed: "Xia Qing, your imagination is too rich. ”

Xia Qing bit her lip and blushed slightly: "You two are really unreasonable, where are we now?" This is Lian'er's 'palace', this is not a civilization on our planet, they were able to come here more than 5,000 years ago, they have this ability, so even if my assumption is exaggerated, it is by no means exaggerated. ”

Gao Chao thought about it and felt that what Xia Qing said made sense, since they entered the ancient city of Yinshan, everything they encountered was very incredible, so even if they made a time-traveling machine, it seemed that there was really nothing.

"Okay." Gao Chao said to Xia Qing: "Even if your conclusion is right, then where we may be now, shouldn't we have been crossed?" ”

Xia Qing said: "It's hard to say, I think since there were so many coffins before, it means that every coffin may be a machine that travels through time and space, and there is a black hole in every coffin, so I think that black hole must not be a natural black hole in the universe, but man-made, that is, the kind that does not cause harm to the human body, you know, the mass of the black hole is very large, if we are really next to the black hole, then we may have been crushed a long time ago, and the artificial black hole just now also has an impact on us, I now understand why we feel cold, because when the black hole is enveloping us, the gravitational pull generated by its mass concentrates our blood in the epidermis, so that we feel cold, and the brain is ischemia, and even our thinking and movements become slow. ”

Gao Chao was stunned when he heard this, but he felt that there seemed to be some truth, and he said to Xia Qing: "If we are crossed, then where are we most likely to be worn, imagine where will Lian'er and them wear themselves?" ”

When the fat man heard Gao Chao say this, he couldn't help but turn pale: "I said Lao Gao, don't be alarmist, if you accidentally wear it to the moon for us, then how can you stop cooking." ”

Gao Chao was also a little worried when he said this: "Don't really say it, didn't Lian'er say what happened to the moon before?" I don't know if they really brought us to their base camp. ”

Xia Qing shook her head: "That's unlikely, I remember that Lian'er once said that she wanted to use this giant tower to go back to her hometown, but she first had to find one thing, which was said to be a device, if that device could still work, she would be able to realize her plan." ”

Gao Chao frowned: "But Lian'er is gone now, and we don't know if she is dead or alive." ”

Xia Qing said: "Don't worry, Lian'er must be fine, I have a hunch that the reason why she disappeared temporarily is to protect us." ”

The fat man didn't seem to believe it: "Protect us? She's so weak, I've been carrying her all the way, how can she protect us? ”

Xia Qing said: "I didn't mean that, I can't say clearly, but every time she disappears, it seems to be a special point in time, and she disappears by herself." ”

The fat man seemed to be unconvinced, and wanted to open his mouth to debate, Gao Chao saw him like this, and hurriedly said: "Don't discuss the problem of Lian'er first, if you come, you will be safe, we have to face the reality now, since we have come to this place, we have to find a way out of here, and then find a way out." ”

The fat man sighed: "It's easy for you to say, you look around, there is no sky and no earth, everything that can't be seen at a glance is white, I wonder, how can there be such a place in this world?" ”

Xia Qing seemed to be reminded by the fat man: "What did you just say?" ”

The fat man was stunned: "What's wrong?" I said, how can there be such a place in the world? ”

Xia Qing suddenly fell into deep thought, and then muttered to himself, "There really is no such place in this world. ”

Gao Chao exclaimed: "Miss Xia, what do you mean, you shouldn't mean that this place has reached another world, right?" ”

Xia Qing shook his head: "That's not what I mean, but I seem to understand that there must be another space in this giant tower, a space that belongs to them." (To be continued.) )
