The instrument in front of me is like a clock that is constantly running, slowly rotating according to fixed rules, I don't know where its power comes from, but it is certainly not simple, I know at a glance that this is an antiquity, and it is no problem for hundreds of years.

There is no perpetual motion machine in the world, but the one in front of you can almost be equated with a perpetual motion machine, according to the fixed frequency, without deviation for so long, its power is far more incredible than its exquisite structure.

The fat brother exclaimed: "This thing is a cow, it can't be a Rolex brand, right?" How is the Fast Research study time indicated? ”

It seems that the fat brother sees this thing as a clock, and it is not surprising, judging from its mechanical movement and the sound it makes, it is not impossible for it to be a timer, but after spinning around the big ball for a long time, I don't see anything to do with time.

Jiang Rou reminded me: "Zhanxiao, you stay away from that thing, maybe it's some kind of trap, be careful, I've never seen this kind of thing, and there is no record in the book." ”

I hurried back to everyone, regained a sense of security, and said to everyone, "Then let's go quickly, I listen to the voice, I always feel that this thing will explode." ”

The fat brother took the scimitar behind his back, hunched his waist, measured his steps, and approached the device.

Jiang Li asked the fat brother, "What are you going to do?" Be careful, if it's really a mechanism, there must be a self-protection device. ”

The fat brother turned his head and lowered his voice and said, "You guys be quiet, in case it's voice-controlled." ”

As soon as the fat brother's words fell, he saw Su Rina on the other side of the fat brother suddenly jumped up and slapped the fat brother on the back with a shout.

The fat brother's face suddenly turned pale, and he sat on the ground all of a sudden, and his eyes were stunned for about two minutes, before he turned his head to look at Su Rina, who was already laughing unsteadily, and muttered: "Are you crazy?" My heart was stopping. ”

Su Rina put away her smile and said to the fat brother: "It's not voice-controlled." Then he laughed maniacally.

We originally suspected that Su Rina was under too much mental pressure, and suddenly began to go crazy, only then did we understand that she was joking with the fat brother, thinking about the performance of the two of them like circus clowns just now, we couldn't help but join in laughing at the fat brother.

After laughing enough, I asked Surina: "How do you know it's not voice-activated?" Looks like you know it's not a dangerous trap? ”

Su Rina said: "Why is it dangerous? This thing can be seen at a glance, there is no structure that can hurt people, and there is no hole to launch a hidden weapon, it must not be a trap. To say voice control, it is even more impossible, the general voice control things are very sensitive, in order to ensure the trigger of voice control, a relatively quiet environment will be chosen to install, it emits such a loud mechanical sound, how can it be voice control? As far as I can guess, this is an instrument that records something, isn't there the Big Dipper on it? Is it a record of any astronomical science? After speaking, Su Rina looked at Yan Qiu and waited for Yan Qiu's confirmation.

We all followed Su Rina and looked at Yan Qiu, who was frowning and silent.

The fat brother stood up and patted his pants while teaching Su Rina: "If you have something to say, you can say it well, is this the time for a joke?" I'm going to get older, I'm going to scare you to death, it's stressful enough, don't put unnecessary pressure on me. ”

Su Rina said with a face full of grievances: "Didn't I use a joke to relieve your pressure? When did you start getting serious? ”

In fact, I know that Su Rina has good intentions and wants to help everyone reduce stress in this way, but also to release the long-term depression in her heart.

Just as he was about to help Su Rina speak, Yan Qiu spoke: "This should be a stargazing scope, which is used to compare the direction of the Big Dipper and the Earth's orbit. ”

"Earth? Where is the earth? The fat brother asked Yanqiu.

"Isn't that a globe in between? The outer layer is the Big Dipper, and I estimate that the outer layer does not rotate, but moves according to the earth's rotation period, that is to say, the ball inside rotates 365 times, and the bronze plate on the outside moves. After Yan Qiu finished speaking, he looked at everyone, waiting for us to think about it.

I looked at the two-layer sphere carefully, and I couldn't see the characteristics of the earth, so I drew the globe in my mind on the sand with my hand, and said to Yan Qiu: "Look, this one I drew is a globe, which is completely different from what we see, it can't be other planets, right?" ”

When Yan Qiu saw the same expressions as me, she realized that none of the six people here saw this ball as the earth except herself.

Yan Qiu took a deep breath and said, "I'm sorry, I ignored your understanding of relevant knowledge, now I'll tell you why this is the earth." ”

With the rotation of the ball in the middle, Yan Qiu began to analyze us: "You look at the irregular blocks that are gathered and scattered on the outer frame, those are actually the plates of the earth, and the central part is a mechanism that can make the outer plates move in a fixed orbit with the rotation of the entire sphere. From the beginning, the continents were mostly distributed in the north and south poles, until now the distribution of seven continents and four oceans, and even the change law of the earth's crustal movement in the future. ”

When the plates above moved to a certain part, Yan Qiu said, "Look, this is the current distribution of our earth continents. ”

I've seen globes and maps, and I can basically see the shape of each continent, but when Yan Qiu asked us to look at it, I still couldn't see the shape of the earth's continent at all.

Others didn't seem to agree with Yan Qiu's statement, and they all said that they didn't look like it.

Yan Qiu continued to explain: "Don't worry, listen to me slowly. ”

It turns out that it is normal for us to look different from the earth's plates, and after listening to Yan Qiu's explanation, we know that this globe is very rigorous, and the plates it displays include not only the land above sea level, but also the continental shelf.

The continental shelf is the part of the continent that extends to the ocean, and if the shape of the continental shelf around the continent is added, the shape of the continent we see is naturally different from the one on the map.

"Do you mean the maker or is he from Earth, a scholar of astronomy? This thing was built to record the location of the Big Dipper? Jiang Li asked a question, walked to the iron plate with holes, leaned up, and watched the movement of the globe through the holes above.

Yan Qiu replied: "It's really hard to say whether it's from the earth or not, I can't tell the age of the construction of this thing, but I speculate that it is earlier than those stone tablets, because it is in the innermost part, and the stone tablets are all built with it as the center and fan-shaped spreading." At that time, the earthlings didn't know whether to wear clothes or not, so how could they study the drift of plates? Even now, the theory of the drift of the Earth's tectonic plates is only at the stage of conjecture, and the evidence found can only prove its possibility. ”

The fat brother also followed Jiang Li's example and lay down, looked at the hole for a long time, and didn't see any clues.

When I was about to take a look, I suddenly noticed that something was wrong, so I grabbed the clothes of the fat brother and Jiang Li and pulled them to my side.

When they no longer stood in the way of the perforated arched iron plate, I was surprised to find that it was not the Big Dipper at all, but six holes arranged in a spoon shape.

And this six-hole spoon shape, I just saw before, is the spell technique used by Jiang Rou when he subdued the phaseless ghoul, called the Six-Character Demon Breaking Array.

I pointed there and shouted, "Six holes, Jiang Rou, look at them, those are six holes, the same as the talisman you pasted on the wall." ”

After I reminded you, everyone gathered around, and a simple count will understand that there are indeed only six holes, and these six holes happen to be arranged in the shape of the Big Dipper, although it is somewhat different, but the original arrangement of the Big Dipper is not very clear to us, probably like this.

Jiang Rou said proudly: "Hey, you see, right?" I have a history of this spell, and the ancients have long had this arrangement. ”

The fat brother scratched his head and said, "Then is this the Big Dipper?" ”

Yan Qiu said: "If you want to ask about ancient geography, I still know something, if you want to ask astronomy, I don't know anything, maybe the ancient people couldn't see the seven stars, and there were only six Big Dipper stars at that time?" ”

Jiang Rou still objected: "My spell technique has nothing to do with the Big Dipper, maybe you are wrong, this is another constellation." ”

Another constellation?
