I regret the flashlight I wasted at the fork in the road. Pen ~ fun ~ pavilion www.biquge.info at the moment, in order to save energy, the remaining two flashlights are only turned on, and at the same time all the mobile phones are turned off, once the battery is exhausted, the mobile phone can also be used as a light source, and there is no signal here at all.

After everything was arranged, Hong Kaiyuan and I each carried a bag, Wen Jing traveled lightly, and the three of them prepared to set off again.

I asked Hong Kaiyuan if he had searched this cave hall, and asked him which passage he came in from.

Hong Kaiyuan scratched his scalp and said that he had forgotten, as soon as he came in, he walked to the middle of the cave hall, and when he found this stone platform, he was attracted and did not search.

I was a little speechless, sighed and said: "Then let's stand in a row, the girl will use a flashlight in the middle, and the two of us will be left and right, and then we will conduct a carpet search!"

Wen Jing didn't say anything, Hong Kaiyuan laughed when he heard it, shone a flashlight on me, and said in a very ambiguous voice: "Little sample!"

"I see that you two are really not worried at all, you still have the heart to joke at this time!" Wen Jingxing's eyes widened, and she glared at me and Hong Kaiyuan fiercely. Obviously, this time, she heard Hong Kaiyuan's intentions.

In order to avoid embarrassment, I scolded: "You dead fat man, don't you turn off the flashlight quickly, it's a waste of resources." Now it's just the one in the girl's hand!"

Hong Kaiyuan smiled and turned off the flashlight, but his mouth still didn't stop: "Lao Tzu knew that you wanted to fish in troubled water!" Hearing this, I went up and gave him a violent chestnut.

Then, the three of them began to wade through the thunder.

After the three of them stood in a row, they first chose a direction, and then began to move forward slowly. As I judged at the beginning, this cave hall is very large, and when we approached the cave wall, we realized that from the stone platform in the middle to the cave wall is almost seventy or eighty meters, if the stone platform is the center of the cave hall, then the area of this cave hall is quite large.

When I got closer to the cave wall, I realized that the cave wall was indeed at an angle to the ground, about fifty or sixty degrees, and the cave wall was inclined upward, but the top could not be seen at all. I took a closer look at the junction between the ground and the wall of the cave, and found that there were no gaps in the cave at all, and the whole cave hall seemed to have been pulled out of a huge stone. I can't help but sigh in my heart: what kind of project is this!

There is nothing unusual about the cave wall, and it can only be judged that it is granite, and it is definitely excavated with some kind of tool.

In this way, the three of them searched back and forth in the cave hall in a carpet manner, and it took almost half an hour to find nothing but three passages on the cave wall.

Although we found nothing, I was very happy with the results of the search. Among the three passages, the passage when Hong Kaiyuan came in was different from mine, and he also made a mark at the entrance, so it was much simpler next. Because there is only one passage left in front of us.

Eventually, the three of them came to a halt at the unmarked entrance to the cave. We decided to take a break first and grab a bite to eat.

I looked at the time, and it was almost five o'clock in the morning. After tossing for a long time, everyone feels a little tired. To be honest, our backpacks are indeed not light, and it is really tiring to carry such a trip.

"I said Lao Qi, we don't seem to have found anything here?!" Hong Kaiyuan sat on the ground with his bag, panting.

"This place is really big, I counted my steps just now!" Wen Jing also sat down.

"Sister, you are really careful!" Hong Kaiyuan smiled, "Your imperial brother, I also made a rough calculation, the length should be about one hundred to one hundred and seven meters, and the width should be about one hundred to one hundred and ten meters! But it seems that this dome is very high, and it is impossible to see at all!"

I didn't count this, so I asked Wen Jing, "Girl, what are the steps you take on each side?"

"It's strange to say, because we have repeatedly sifted like weaving cloth in the east-west and north-south directions, and each direction has been repeated n times, but the number of steps I count each time is about five hundred and sixty steps in the north-south direction, and about three hundred and forty-six steps in the east-west direction, which is almost one or two steps up and down!" Wen Jing thought for a while and replied.

I groaned for a while, then asked Wen Jing to stand up and take a few steps, then asked her to stop moving, and then measured her stride distance with my hand, repeating it a few times, and I quickly had a result in my heart.

"Lao Qi, why the are you tossing the girl? Didn't I say it, I can't calculate it badly! Besides, in such a big place, it is normal for an error of a few meters or ten meters, and besides, is this important?"

I ignored him, began to calculate silently in my heart, then thought for a while, turned back to Hong Kaiyuan and said: "If the girl's number is correct, plus the results of your calculation, the accurate data of this place should be one hundred and sixty-eight meters long, and the width is nearly one hundred and three .8 meters! I measured the girl's stride just now! Her stride should be thirty centimeters!"

"Damn, isn't it, it's so accurate?" Hong Kaiyuan was a little puzzled, paused, and continued: "Is this number important?

I sat down across from him, turned around and motioned for Wen Jing to sit down.

I'm a designer myself, so I'm extremely sensitive to numbers!

Therefore, I have secretly calculated the number of holes in the groove on the stone platform that has disappeared and the relationship between their distribution, and I always find it so strange that I dare not believe it!

And if my calculations are correct, the size of the cave hall I determined just now makes me even more confused. Because, I have a big specialty, and that is that mental arithmetic is quite accurate. If the width of the cave hall is removed from the length of the cave hall, the result is actually 0.618, isn't this the golden ratio? There is a more coincidence in the world?

My intuition tells me that this is obviously not a coincidence, but someone deliberately did it!!, but what the purpose is unknown!

When I finished all my thoughts, Wen Jing and the others didn't say anything.

After a while, Hong Kaiyuan finally spoke: "Originally, if it hadn't been for those things just now, then I can only think that your inference just now was a coincidence! But now I can't refute you!"

After a pause, he said again: "Lao Qi, how did you think that using the aspect ratio is the golden ratio?"

"It's nothing, my professional habits! I toss around as soon as I see the data, and in my usual design work, I like to use the golden section the most, because then the design will be quite beautiful and reasonable!" I took another puff of my cigarette and continued: "What I am most concerned about now is the distribution of the number of holes in the groove that has disappeared, it seems to be regular, and as for why they appear here, it is what puzzles me the most!"

Sighing again, I said slowly, "Don't you think it's strange that there are nine faces? And you still say that they are very familiar, don't you see anything?"

"I really haven't seen this, I just feel as if I've seen it somewhere, and I have a little impression, but I can't remember it at all for a while! But your words sound as if you already know what these numbers mean!"

"If all the holes on it are just numbers, then the arrangement of those nine numbers is very strange!"

Hearing this, Hong Kaiyuan and Wen Jing both said "oh?" at the same time.

"If you put these nine numbers on a flat surface, you will have exactly three lines horizontally and vertically!" I gestured, then took a deep breath and continued: "Moreover, you have not noticed, if you add these nine numbers in the three directions of horizontal, vertical and oblique, what do you see?"
