The floating sand at the bottom of the cave was very soft, and Zi Yang digged up like a dog. Su Rui also came over and dug out with him. After a while, the gap under the Xuanbing was taken out by the two of them, which was enough to allow people to pass through. Under the light of the diving suit, the cave seemed to emit a blue-blue light - it was empty inside.

Su Rui leaned in and observed it. There was a gap inside. I don’t know how long it was, so it would be fine 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 take a look! It's time to this point, I've tried my best."

Su Rui's face opened with a smile. In this situation, this smile was a bit far-fetched.

Zi Yang said again, "I'm opening the way in front, you're behind. If you encounter a gap that cannot pass through, I'll warn you."

Su Rui shook his head, "No, I'm in front, I'm smaller than you, and it's easier to pass through - and even if it's stuck and you have a lot of strength, you can pull me out."

Zi Yang understood that it was meaningless to argue with Su Rui at this time, and it was not the time to show personal heroism. What she said made sense.

At this moment, the two of them began to crawl forward one after another. After a while, they found that their worries were unnecessary. The gaps were getting wider and wider and bigger. In just a few minutes, the two of them could even walk upright!

At this time, the black ice on both sides of the cave wall gradually changed, and a bright blue light appeared faintly. As we walked, the light on the diving suit suddenly turned off. Only then did the two realize that the strong light on the cave wall was enough to illuminate everything around. After the diving suit sensed the light source intensity, it turned off automatically.

At this time, there was no time to think about where the light source came from. The two of them used their hands and feet together and accelerated their movements. They walked forward for about a few hundred meters. They faintly felt the gap gradually rising. After a while, the water surface appeared on their heads.

The water level around him gradually decreased. As he walked, the water surface disappeared. After a while, the two of them stepped onto the solid land - in front of them was a corridor three or four meters high and five or six meters wide. Under their feet were huge ice patterns and gravels of all sizes.

The corridor is half-arc, and the walls of the cave are still extremely hard and ice. The walls of the cave are covered with dents of about a square foot, as if they are rippling. It seems that they have been melted by something before.

Zi Yang was shocked by the scene and couldn't help but use his hands to touch the fish scale-like ripples, and his 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 read: "The temperature is 22 degrees Celsius, the atmospheric pressure is 100,000 pa, the air component nitrogen (n2) 78%, and oxygen (o2) 21%.

Although geography is not good, Zi Yang understands the significance of this string of data - a standard atmospheric pressure, and the air composition is almost the same as the normal breathing environment for humans.

At this time, the two of them noticed that the extremely hard nano-dive suit on their bodies also became softer again. This shows that the internal and external pressure has been balanced.

Zi Yang wondered: "Although I haven't read many books, based on the road we walked just now, it is still quite far from the ground. According to the principle of pressure balance, there should be very high pressure here so that water will not pour in."

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

Zi Yang was a little dizzy. Everything he encountered since entering this abyss seemed to violate the current physical common sense that humans have known.

When Zi Yang was shocked, she suddenly found Su Rui taking off her hood! Zi Yang was shocked and waved her hands at Su Rui repeatedly, shouting, "Danger!"

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

After comparing each other for a long time, the two suddenly realized that the diving suit mask had the effect of isolating air. They did not turn on the sensor, so they could not talk.

Su Rui took off Zi Yang's hood without saying a word.

Zi Yang was so scared that he took a deep breath and was about to hold his breath.

Seeing that Zi Yang's cheeks were bulging like a bun, Su Rui burst out laughing.

"Don't worry, it's tested. This is the standard environment for human survival. The air is very fresh and pure! You see, I'm not doing well?" He said, shook his hair and looked like he was dancing lightly.

Su Rui tapped the solid hole wall again with his fingers. Without a light source, the black ice was still emitting a blue-blue light. "I don't know what the black ice is. At this temperature, it can still remain solid. Unfortunately, the sensors on our hands are limited in function and cannot analyze the specific components. Just take some samples back..."

Zi Yang exhaled a turbid air from his chest, then touched his head and was a little shaking, "Oh, I'm a little drunk..."

Su Rui looked around curiously, "Go ahead and take a look." After that, he ran forward with his helmet.

Zi Yang was breathing heavily with his knees behind him. He was a little girl. He was so scared that he was like a separation from life and death just now that he was jumping around in a blink of an eye. He seemed to have forgotten that there were Lao Wang next door and the half-dead Alexander above the abyss.

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

Afraid of Su Rui's accident, Zi Yang took a breath and followed him. From a distance, he saw Su Rui's body standing there motionless, as if he had seen something incredible.

When he ran to Su Rui, Zi Yang was stunned for a moment. There was a wide space in front of him, as big as a stadium. A few hundred meters above the top of the cave, there was a luminous body similar to a small sun, occupying the area of ​​1/2 of the cave top. The light on the surface of the luminous body surged, sprinkling soft light at the bottom of the cave, illuminating the entire cave like daytime.

There are countless sharp stone cones hanging down on the top of the cave, and giant stone pillars on the cave wall tilt into the air. From a distance, the entire cave presents a rugged scene of ancient times.

I don’t know if there are any strange microorganisms attached to the cave wall. Under the illumination of the "little sun" on the top of the cave, it shines with dark purple light. Just below the small sun, there is a circle of monument-like giant stone pillars, like some kind of huge crystal stone, emitting a chaotic dark purple light, pointing in the center.

Too magnificent!

If this is natural, it can be said to be a masterpiece of magical skills.

If this is done by manpower, it can only be described as ingenious work.

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

"This, what the hell is this?" Zi Yang also came to his senses.

Su Rui did not answer, took a gentle step forward, stepped on the dark purple ground, and a piece of phosphorescence radiated.

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

Su Rui shook his head, raised his arms and smiled at Zi Yang, saying, "It's useless, the instrument has failed."

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

Zi Yang slapped his thigh in regret: "What's the situation? It's been fine just now!!"

Su Rui said with a smile, "From the moment we entered the cave entrance, everything that happened here can no longer be explained by human knowledge."

After saying that, he stretched out his hand to Zi Yang and said, "Don't you plan to accompany the lady to enjoy this spectacular and gorgeous scenery up close?"

Zi Yang looked at Su Rui's hand and smiled like a flower. She instantly felt that the invitation had irresistible charm. She nodded and said, "Well, I'm dead under the pomegranate skirt - Uh, no, if you can witness the miracle of nature with your own eyes, that's worth it!!!"
