I don't know how long it took, the two of them kept falling into the darkness, and they didn't know how many meters they had dived. It seemed that there was no bottom below. Zi Yang became more and more frightened. The helmet light could only illuminate a little distance in front of him. The rest of the place had turned into darkness. Although the diving suit would automatically adjust the structure to adapt to the pressure, Zi Yang still felt a strong sense of oppression. His breathing began to be a little rapid and his heartbeat accelerated sharply. Zi Yang knew that this was a subconscious mind, but he could not control himself and not panic.

Su Rui felt his abnormality and squeezed Zi Yang's hand with his right hand, and wrapped his left hand around Zi Yang's waist from behind to maintain his diving movement.

Zi Yang turned his head and saw Su Rui smiling at him in his helmet. This smile made Zi Yang quickly stabilize. Although the diving suit is very isolated, in theory, he could not feel the temperature of Su Rui's body, but he felt that there seemed to be a warmth from where the two of them were in contact. This strange feeling made him no longer feel lonely.

Suddenly I felt that I wanted to be together like this, the sky was dark and the earth was never separated.

Zi Yang was thinking about it all over the place, but Su Rui focused on staring at the sensor on his right hand, with rows of numbers of different sizes flashing with fluorescence and constantly changing.

"Let me talk for a few words, I'm a little scared. It would be much better if I have a beautiful woman by my side." Zi Yang suddenly laughed. This endless silence made him more and more nervous. If he continues like this, he may be mentally broken.

Su Rui also smiled, "I thought you were different from Lao Wang. You were a serious person, but I didn't expect you to be as slick as well."

Su Rui couldn't help but admire Zi Yang. He was nervous just now on the verge of collapse, and he adjusted so quickly. His psychological quality was amazing. Such deep diving was a bit nervous for himself who had received strict training. This man who had never dived before could hold on until now.

Su Rui knew that the biggest obstacle to deep diving was not the physiological aspect, but the psychological aspect. Deep water is like a dark and confined space, which can easily cause psychological claustrophobia in people. In addition, extreme darkness will make people feel extremely depressed. At such a level of deep diving, even professional divers will suffer from deep sea phobia, let alone ordinary people.

Su Rui frowned and looked at the numbers on the sensor. The depth of the pool water was far beyond her expectations. No matter what, she could not imagine that there would be such a structure under the pool water of more than a dozen square meters, which even exceeded her cognition... It would be great if Alexander was there, and he might be able to explain this phenomenon.

Zi Yang's voice came from his helmet: "I'm sorry, I haven't supported your work all the way - do you think I hate it?"

Su Rui said seriously, "No, I think you and Lao Wang are both very good people..."

Zi Yang explained, "Although Lao Wang is straightforward, he has a good heart, and he treats you..."

Zi Yang was about to continue talking, Su Rui suddenly said: "It's the end!"

Zi Yang felt a shock under her feet, and her feet had already touched the bottom of the water.

Zi Yang looked at the detector. The strings of numbers, squares, and graphics are marked in English, and they can't tell anything at all. He only vaguely identified a module that should record his own heartbeat. There is a heart-shaped sign on the upper left of the module, and the number on it shows 81.

Su Rui read gently: "The diving depth is 978 meters, the pressure is 10∧7pa. The water quality components sodium chloride, potassium sulfate...the external temperature is 0.5 degrees Celsius."

Zi Yang was stunned when he heard this, "Is the sensor wrong? Is there a problem with this number? Although I did dive for a long time just now, it is 978 meters?"

Su Rui looked at Zi Yang's sensor and compared the data. "I don't believe in this result very much, but the numbers of the two sensors match, and even if they fail, they will not be wrong."

Zi Yang still couldn't believe it: "The limit of human diving is only more than 330 meters. At this depth, our body has long been squeezed out by water pressure." Zi Yang moved his limbs, without any obvious abnormality, but he felt that the joints of the diving suit were a little difficult, as if they were rusted.

Su Rui explained, "Alexander introduced me to the physical characteristics of this diving suit, which involves very high-end technologies and materials. I am not particularly clear about it. I only know that the nanostructures inside this kind of clothing can support extremely high pressure and do not need to balance internal and external pressure, so even without decompression and buffering, you will not suffer from diving."

"We felt awkward in motion, which may be caused by the deformation of the nanostructure under extremely high pressure - but this is already amazing, and it is the first time I have seen such a result. You see, the junction of the structure remains flexible and can rotate freely." He waved at him.

Zi Yang looked at Su Rui in disbelief, carefully looked at his hands and feet to see if there was any crushing or something. It was normal. The diving suit slightly raised and was put on his body like armor. The originally smooth and soft surface actually showed a metallic luster.

"It seems that nothing is unusual about the diving suit, but its internal structure has changed. If you don't believe it, please touch it here." Su Rui took Zi Yang's hand and touched his abdomen. Sure enough, the tentacles were as hard as iron.

Zi Yang asked, "No matter how hard nanomaterials are, they still have pressure limits, right? Alexander hasn't told you?"

Su Rui shook his head and said, "Alexander told me about the theoretical limits measured in the laboratory. However, due to the lack of sufficient environmental conditions, we have not tested them on the spot. However, at present, we are safe."

"What is the theoretical limit?"

Su Rui: "800 meters. The water quality density in the deep pool is even higher, and the theoretical limit may be only 5 or 600 meters."

Zi Yang: "I'll go..."

Su Rui comforted him and said, "Don't worry, I have been observing the data when I dive, and I will stop the action if there is any danger."

This was to make Zi Yang feel at ease, but it did not have the appropriate comfort effect. Zi Yang turned anxiously in the spot: "What are we waiting for? If we don't find anything, we will go back."

Although the pressure in the diving suit remains normal, Zi Yang feels unprecedented depression in this claustrophobic space - unlike the previous feeling, he begins to become anxious. After returning this trip, he may suffer from deep-sea phobia.

Su Rui said slowly, "Wait a minute, the detector is still analyzing the surrounding environment."

Zi Yang was a little dazed, not just walking there or sitting there, so he had to hold Su Rui's hand tightly. It seemed that he could feel Su Rui was also a little nervous, and his voice was shaking slightly.

Zi Yang blamed himself in his heart, only considering his own feelings, and did not realize that it was the first time Su Rui had experienced this situation. Moreover, he was a girl, younger than him, but he was mature and steady when things happened.

While suppressing her inner fear, Zi Yang tried to communicate with Su Rui to relieve her nervousness.

Zi Yang gently patted Su Rui's back of his hand, although he knew that under this external pressure, his strength was like an ant scratching an elephant, and the other party could not feel it at all. He comforted Su Rui and said, "I'm sorry, I was a little out of control just now."

Su Rui's body relaxed a lot, and the sound coming through his helmet was much calmer than before. "You have surprised me. I have undergone rigorous professional training, but the first time you dive so deeply, and you can't even be a dive beginner, you can still adjust your own mentality... Most people have long been psychologically broken."

Zi Yang: "Aren't you afraid that I will collapse and go crazy halfway?"

Su Rui laughed: "I have been monitoring your signs and data. Even if there is any accident, I can still control it remotely..."

When Zi Yang heard Su Rui say this, he was a little confused and was about to ask Su Rui what "remote control" means.

Su Rui suddenly said, "The detection result is so strange."

Zi Yang asked, "What?"

Su Rui said, "If the instrument had not failed, the cave structure here had undergone strange changes." He said, pulling Zi Yang's hand upstream.

The diameter of the surface of the pool is only more than ten meters. After reaching the bottom of the cave, the margin slightly expanded and the diameter has exceeded thirty meters - at this depth, it is already a very straight passage.

Through the lights on the diving suit, Zi Yang was surprised to find that the cave wall was not the stone he imagined, but the extremely thick - Xuanbing.

Su Rui said, "It's strange that part is water and part is ice. The composition of the two kinds of water is definitely very different."

Zi Yang touched the hole wall, which was smooth and hard, and the light could not penetrate. The ice wall in front of him was afraid that it would be dozens of meters thick. Zi Yang asked, "Is it caused by too high pressure?"

Su Rui refused to say that: "Water is different from other substances. The liquid will not become solid under the same temperature when pressurization of the liquid. Generally speaking, when the water depth reaches a certain depth, the temperature will stabilize at around 4 degrees Celsius. The water quality here is denser, so it is understandable that the temperature is lower, but why do there are two forms at the same time?"

Zi Yang doesn't think this is a big problem - the existence of this abyss is originally contrary to physical common sense.

Zi Yang suddenly thought of something, "Have your detector detected - ahem - organisms, microorganisms just now?"

Su Rui called out another set of data from the curved screen and exclaimed: "The water here is very pure - absolutely pure. Not only does there be no organisms, but also the number of microorganisms is equal to zero according to the results of the instrument detection."

Zi Yang understood what this means to zero. Generally speaking, even the harsh water quality environment will have organisms. At the entrance of the volcanic cave under the sea, even if the water temperature reaches several hundred degrees, a kind of shrimp will still survive.

But at the bottom of this ice cave, the microorganisms are actually equal to zero!

Zi Yang has seen the accuracy of Alexander's equipment. Judging from the current situation, the chance of failure is very small.

Su Rui was stunned and at a loss on the spot. Zi Yang crawled down and groped with his hands along the junction between the bottom of the hole and the wall. Su Rui looked at him with a little strange, "What are you doing?"

Zi Yangdao, “Find an exit.”

Su Rui said with some regret, "The detector shows that the bottom of the cave is also closed, and we are in a dead end again."

Zi Yang kept busy with his hands and feet, comforting Su Rui, "There is no way out."

Su Rui sobbed gently.

Zi Yang: "You foreigners believe in machinery and instruments too much. Sometimes the instruments are not accurate. Computers are just stupid and can't turn. At critical moments, human instincts are more reliable."

Zi Yang actually had no idea, but he just felt that this should not be done. Since entering the desert, he had encountered such boundless darkness several times in his dream. He had a premonition that in the abyss, there seemed to be an ancient ghost summoning him.
