After entering the tunnel, we realized that this tunnel, which looked like a ring in appearance, was actually built to imitate the saying that the sky is round and the place is round.
Walking in the tunnel, the top of our heads is an inverted semicircle, and the bottom of our feet is a rectangular strip that feels like cotton.
The two walls of the tunnel and the top of the head are covered with murals of auspicious clouds. The painting method is similar to the auspicious clouds I saw in the ancient pagoda underground palace.
"Just now I was wondering if I would enter the time and space tunnel after taking this step. Who would have thought that I would still be back to the archaeological model - corridors + murals, hahahaha," it was quiet in the tunnel,
Everyone was probably swimming forward in a cautious state, fearing that if they took a careful step, they would stab a snake's nest, so Andrew's joke was a timely blessing, and the atmosphere suddenly became better.
"Professor, if we could enter the space-time tunnel, wouldn't we be able to rewrite our own lives?" Xiangyu continued what Andrew said.
"I think that even if there is a space-time tunnel, we will not be able to rewrite history. Have you ever heard of Fermat's law of least time." Zhang Jisheng also joined this topic.
As soon as I heard Fermat, I immediately became energetic and almost asked him before he could speak: "Jisheng, what is Fermat's law of least time? Please tell me."
"The actual route chosen by a beam of light is always the fastest one, no matter what path it takes." Zhang Jisheng said.
"I know, but what does this have to do with the space-time tunnel we are talking about?" I still find it difficult to understand.
"Our human thinking is linear thinking, so what we see is limited by the timeline. But if we jump out of the timeline now, what do you think we might see?" Zhang Jisheng seemed to be deliberately telling the truth.
"The cause and the result are the same." Xiangyu said suddenly.
"Yes, so no matter what kind of time tunnel we walk into or how we get the result, the result is always there and does not change because of the change in the path we reach."
After listening to Zhang Jisheng's words, something seemed to flash through my mind. It was a very important thing, related to those words and the experiences of all of us.
However, I couldn't catch it, it was like water in my hand, slipping away from my mind little by little, but I knew it had come.
"No, there's something wrong with the mural," Andrew said suddenly while I was still lost in my own thoughts, then turned around and swam back quickly.
We didn't know what he suddenly thought of, but judging from his behavior, it seemed to be something more important, so we swam back together.
"Professor, did you find anything? What's wrong with the mural?" Xiangyu asked through the intercom.
"We were all deceived by those painted clouds. The real content of the mural is hidden behind these clouds," said Andrew.
I saw him swimming to the entrance, then getting close to the tunnel wall and observing carefully.
When we saw this, we all followed him.
Sure enough, after careful observation, I found that there were very fine lines carved on the tunnel wall. Because of the preconceived influence of the water flow and the auspicious cloud murals, it would be difficult to find such patterns hidden behind them without careful observation.
"It turns out that the murals misled us." I didn't know why, but I suddenly said this.
"No, the mural did not mislead us. It was because we were fixed by our past thinking and thought that auspicious clouds were just auspicious clouds. It was Zhang Jisheng's words just now that reminded me that the owners of the bottom of Poyang Lake may use a completely different method from us.
This is my way of thinking, so the auspicious clouds may just be part of the mural, so I carefully observed the tunnel wall, and sure enough I discovered these fine lines." Andrew seemed particularly excited, and his tone of voice was much faster.
"Do you know what is painted on the inner wall of this tunnel?" I asked a little impatiently.
"It's a star map." Xiangyu said calmly.
"Jade, you are indeed my most outstanding student, you can see it right away." Andrew said as if he was a little surprised.
"Professor Andrew, you are very grateful. I also discovered it under your inspiration." Xiangyu returned to her original delicate tone.
"Xiangyu, how did you know it was a star map?" Zhang Jisheng asked.
"Don't think of this place as a tunnel, but imagine it as a sky. Remove all these material things, abstract the murals and auspicious clouds, and you will be able to create a star map in your mind." Xiangyu said.
.
"I can't do it anyway," I chuckled twice, and then asked, "Why do you want to carve a nebula mural in this tunnel? And in such a hidden way, I really can't figure it out."
"Jade, do you think that the star map painted above is very similar to the M27 nebula in terms of shape and color." Andrew asked.
They started talking again that I couldn't understand, so I listened with my ears but kept my mouth closed.
"It's very similar. Although the Dumbbell Nebula is one of the brightest planetary nebulae in the sky, it is still invisible to the naked eye. It can only be observed with a binoculars or a small astronomical telescope. But professor, look, what are the things in these murals?
The shape of the carved nebula, the dark matter at the center, and the bright nodes inside the nebula, as well as the symmetrical black tails on these nodes are all highly consistent with the observation results of modern astronomy, which feels a bit like
It's incredible." Xiangyu said, and couldn't help but stroke it with his hands.
"Perhaps, everything we encountered at the bottom of Poyang Lake is not man-made." Lao Li said this suddenly, which suddenly reminded me of the creepy words on the walkie-talkie, and I couldn't help but ask my teammates
They got closer.
Xiangyu and the others continued to discuss, Lao Li did not speak, and was suspended in the water, not knowing what he was doing. I stood alone in the center of the tunnel, raising my head and staring at the semicircular roof of the tunnel, imagining these materializations.
Everything disappeared, and then only the blossoming auspicious clouds and the flowing lines behind the auspicious clouds remained.
Gradually, my eyeballs seemed to be covered with a layer of mist, and the things in front of me gradually blurred. Xiangyu, Zhang Jisheng, Andrew and Lao Li all drifted far away, and there was really only that flower left around me.
colorful auspicious clouds.
The blue-black dome gradually shrank, and the stars on it gathered together. I was suddenly shocked. What was depicted in this image was the sapphire astrolabe in the hand of the fish-faced man.
I finally understood why grandma called them astrolabes. These thin stone slices in our hands are probably models of nebulae in the universe.
The people of the ancient temple, the fish-faced people, including grandma’s family, what they have been worshiping for generations is actually not the palm-sized jade that they have passed down from generation to generation, but the nebula. But, what are they doing sacrificing to the nebula?
Is it possible to exchange information during the sacrifice process?
Could it be that the sacrifice of the fish-faced people that I participated in in the long dream was also due to the distortion of time and space? If that sacrifice really existed, then during the sacrifice process, the fish-faced people obtained from the cube
Could it be the words he wrote on the bamboo slips with cogongrass.
After going around in a circle, we still have to start with the words. If we can decipher these words, we will definitely get more information.
My father told me to learn to write these words. Although he did not tell me the reason, he repeatedly emphasized that it must be very important. Therefore, if I can get out of Poyang Lake this time, I must start learning to write.
This kind of text.
Alas, talent aside, my self-discipline and bravery will never compare to my father's.
"Zhou Cang, what are you thinking about? Come on, let's go forward and see if there are any other patterns carved on the tunnel wall."
Xiangyu suddenly pulled me out of my chaotic thoughts.
