The floating sand at the bottom of the cave was very soft, and the poplar was digging up like a dog. Su Rui, www.biquge.info the pen %fun %pavilion, also came to dig out with him. In a few moments, the two of them pulled out a hole under the ice that was square enough for a person to pass through, and under the light of the diving suit, the hole still seemed to glow with a blue light - it was empty.

Su Rui leaned in and observed, there was a gap inside, I don't know how long, it was no problem for people to crawl in.

Looking at Su Rui's inquiring eyes, Zi Yang understood what she was thinking, nodded and said, "Go in and have a look!" It's all come to this point, and Lao Tzu is also out of the way. ”

A slight smile spread out on Su Rui's face, which was a little far-fetched in this situation.

Ziyang said again, "I'll open the road in front, you'll be behind, if you encounter a gap that can't be passed, I'll warn you." ”

Su Rui shook his head, "No, I'm in front, I'm thinner than you, and it's easier to pass - and even if it's stuck, you have the strength to pull me out." ”

Zi Yang understood that it was pointless to argue with Su Rui at this time, and it was not the time to show personal heroism. What's more, what she said also makes sense.

At that moment, the two of them began to crawl forward one after the other, and after a while, they found that their worries were unnecessary, the gap was getting wider and wider, bigger and bigger, and in less than a few minutes, the two of them could even walk upright!

At this time, the ice on both sides of the cave wall also gradually changed, faintly emitting a bright cyan blue light, walking and walking, the light on the diving suit suddenly turned off, and the two realized that the strong light on the cave wall was enough to illuminate everything around, and after the diving suit sensed the intensity of the light source, it automatically turned off.

At this time, they didn't care about thinking about where the light source came from, the two of them used their hands and feet together, accelerated forward, and walked forward for about a few hundred meters, faintly feeling that the gap was gradually rising, and after a while, the heads of the two people actually emerged from the water.

The water level around them gradually decreased, and as they walked, the surface of the water disappeared, and in a short time, the two of them stepped onto solid land - in front of them was a tunnel three or four meters high and five or six meters wide. Beneath your feet are huge ice patterns and large and small gravel.

The tunnel is in a semi-arc shape, and the cave wall is still extremely hard and cold, and the cave wall is covered with indentations that seem to be ripples, and it seems that it should have been melted by something before.

Ziyang was stunned by this scene, and couldn't help but use her hand to caress the fish-scale-like ripples, the tentacles were smooth and hard.

Su Rui glanced at the detector and suddenly exclaimed, Zi Yang was startled by her, "What's wrong?" ”

Su Rui reads: "The temperature is 22 degrees Celsius, the atmospheric pressure is 100,000 pa, the air composition is 78% nitrogen (N2) and oxygen (O2) is 21%. ”

Although the geography is not good, Ziyang understands the significance of this series of data - a standard atmospheric pressure, the composition of the air is not much different from the environment in which humans breathe.

At this time, the two noticed that the extremely hard nano wetsuit on their bodies had also become soft again. This shows that the internal and external pressures have been balanced.

Zi Yang wondered: "Although I haven't read many books, but with the little road we walked just now, there is still a considerable distance from the ground, according to the principle of pressure balance, there should be a very high pressure here, so that the water will not rush in." ”

Su Rui nodded, "You're right, the vertical drop from the ground is 878 meters now. ”

Ziyang was a little dizzy, since entering this abyss, everything she has encountered seems to be contrary to the physical common sense that humans currently know.

When Zi Yang was speechless, he suddenly found that Su Rui was taking off his hood! Zi Yang was shocked, waved his hand at Su Rui again and again, and shouted in his mouth, "Danger! ”

Su Rui took off his helmet, shook his long hair, looked at him with a smile, and said something briskly with his mouth closed.

After comparing with each other for a long time, the two suddenly realized that the wetsuit mask had the effect of air isolation, and the two did not turn on the sensor, so they could not talk.

Su Rui took off Ziyang's hood without saying anything,

Ziyang was so frightened that he hurriedly took a deep breath and prepared to hold his breath.

Su Rui saw that Ziyang's cheeks were bulging like buns, and laughed out loud.

"Don't worry, it's been tested, this is the standard human living environment, the air is very fresh and pure! Don't you think I'm good? As he spoke, he shook off his hair and danced lightly.

Su Rui's finger tapped on the solid cave wall again, in the absence of a light source, the Xuan Ice was still emitting a blue glow, "I don't know what the composition of this Xuan Ice is, it can still remain solid at this temperature, but unfortunately the sensor in our hands has limited functions, so we can't analyze the specific composition." It would be nice to bring some samples back......"

Zi Yang exhaled a turbid breath in his chest, and then touched his head a little shaky, "Oops, I'm a little drunk......

Su Rui looked around the passage curiously, "Let's go, go ahead and have a look." With that, he grabbed his helmet and ran forward.

Zi Yang held her knees behind her and gasped for breath, after all, she was a little girl, she was so scared of life and death just now, and she jumped alive in a blink of an eye, as if she had forgotten that there was still Lao Wang next door and Alexander next door above the abyss.

With such a delay, Su Rui had already run forward dozens of meters away.

Afraid that something would happen to Su Rui, Zi Yang took a breath and followed, and saw Su Rui's body standing there motionless from a distance, as if he had seen something incredible.

Running to Su Rui's side, Ziyang was also stunned for a moment. In front of me is a wide space, the size of a stadium, a few hundred meters above the top of the cave, there is a luminous body similar to a small sun, which occupies 1/2 of the area of the top of the cave, the surface of this luminous body is surging with light, swaying soft light to the bottom of the cave, illuminating the entire cave as if it were day.

There are countless sharp stone cones hanging down from the top of the cave, and the huge stone pillars on the cave wall are stabbing into the air obliquely, and the whole cave presents an ancient and rugged scene when viewed from a distance.

I don't know if there are any strange microorganisms attached to the cave wall, and under the light of the "little sun" on the top of the cave, it shimmers with a dark purple shimmer. Directly below the little sun, there was a circle of monument-like boulder pillars, like some kind of huge crystal stone, emitting a chaotic dark purple light, all tilted in unison and pointing to the center.

It's magnificent!

If it were a natural occurrence, it would be a masterpiece.

If this is a human doing, it can only be described as ingenious.

It seemed that a long time had passed, and Su Rui let out a long breath.

"W-what the hell is this place?" The stunned Ziyang also came back to his senses.

Su Rui didn't answer, and took a gentle step forward, his feet stepping on the dark purple ground, emitting a phosphorescent light.

Zi Yang hurriedly said: "Safe point, test the environment and air quality first." ”

Su Rui shook his head, raised his arm and said to Zi Yang with a smile: "It's useless, the instrument has failed." ”

Zi Yang looked at the curved screen detector, the numbers on it were flickering in a mess, and the graphics were distorting meaninglessly.

Zi Yang slapped his thigh in frustration: "What's the situation!" It was fine just now!! ”

Su Rui said with a smile on his face, "From the moment we entered the cave, everything that happened here could no longer be explained by human knowledge. ”

After that, he stretched out his hand to Ziyang and said, "Aren't you going to accompany the lady to enjoy this spectacular and gorgeous scenery up close?" ”

Zi Yang looked at Su Rui's outstretched hand and looked at her smiling like a flower, and instantly felt that this invitation had an irresistible charm. He nodded and said, "Well, die under the pomegranate skirt - uh, no, to be able to witness this miracle of nature with your own eyes, that is worth it!! ”

Su Rui turned his head and said softly, "Until now, do you still think that nature has created all this?" ”
