Su Rui stopped Lao Wang who was about to dive, picked up a backpack from the pile of instrument packages, and took out two sets of diving wetsuits. I don’t know what material these two sets of "dive wetsuits" were made of. They felt smooth and delicate to the touch. They were originally folded together, but after opening it, there was no crease on the surface.

Su Rui took out two small oxygen cylinders from the box - he had seen James use it in the desert before, and it was filled with high-pressure concentrated pure oxygen, and everyone had seen its power.

Su Rui kept taking out strange things from his bag like a magic trick - two helmets with transparent masks, the same size as a motorcycle helmet, can even be folded.

Looking at everyone's strange eyes, Su Rui introduced: "This mask is made of carbon nano-mixed metal microgrids. It has high tensile strength and electron transmission. No matter how it is folded, it can restore the original design - this is the material for making space elevators in the future."

Then he pointed to the wetsuit and said, "This wetsuit is also made of nanomaterials, which is thicker than ordinary wetsuits. In addition to being closed and insulated, it is hundreds of times stronger than ordinary wetsuits. It can withstand high temperatures of hundreds of degrees and low cold of tens of degrees below zero. It is the main application material for space suits in the future."

Old Wang next door curiously picked up the wetsuit and rubbed it with his hands. This "wetsuit" is only a few millimeters thick, which looks like a skin but not a skin. There seems to be a subtle grid on the surface.

Su Rui continued: "Don't look at the fact that this clothes are only so thin, there are many layers of special materials inside. The special nature of nanomaterials can make the fabric design multiple structures. This diving suit comes with a life-sustaining system and an energy supply system. The circulation system inside can circulate the exhaust gas and the oxygen in the oxygen cylinder. This small bottle of oxygen is hung on the diving suit, which is enough to maintain breathing for more than ten hours."

Zi Yang said astonished: "What is the use of such a high-tech thing designed to be used? Have you expected this deep pool before?"

Su Rui shook his head: "This is an independent ecological suit designed for future humans to suffer catastrophe. It is only the experimental stage at present, and there are only three sets in the world. This expedition may encounter many unknown situations, so Dr. Alexander specially brought two sets here."

When talking about Alexander's name, Su Rui's expression dimmed again.

Zi Yang changed the topic and said, "Is this kind of ecological suit suitable for deep diving?"

Su Rui nodded: "Yes, this clothes are not only sealed, cold-resistant, and high-temperature-resistant, but also can feel the internal and external environment to adjust the pressure by itself - all of this is automatically completed by the built-in nanostructure and does not require manual adjustment."

Lao Wang opened his eyes wide: "My God! You can walk around in space after wearing this thing, let alone diving, right? How much does this cost? How could you get this thing?"

Su Rui smiled, "My uncle is the head of a top international scientific research institution. Their institutions cooperate with military organizations and research institutions from various countries around the world to study the world's highest-end scientific and technological equipment - mainly for scientific exploration, and there are also some military-civilian-grade weapons of destruction that they do not study."

Zi Yang joked, "I guess the information of such high-end and sophisticated things must be absolutely confidential, right? We have seen them all. Are you not worried about what we stole and sold for you?"

Su Rui knew that the young man opposite was easier to win his support than to tell the truth. So tell him the truth, her uncle, Professor Su, had noticed them a long time ago, and this time, inviting him to come was actually a suggestion from Professor Su.

Zi Yang was shocked. What kind of virtue is he? He would be noticed by such a big man. Could it be that the previous incident was leaked? Could it be that Uncle Li? Professor Su is the mysterious leader?

Zi Yang's head was spinning rapidly, and Lao Wang next door didn't expect so many questions. He touched his head and said, "Oh, I'm ashamed, we did some small things to make money for the people. No matter how hard we have all the deeds are, they are internationally famous."

Zi Yang said sarcastically: "No, if our principal wants to say something to your uncle, you have to make an appointment in advance. Such a big man will notice us? What are the abilities of me? I have such a low education!"

Su Rui said seriously, "Education does not mean anything. Many top scientists in the world do not have high education."

When Su Rui said this, Lao Wang suddenly felt very passionate and said with his chest, "Oh, since our uncle is so keen and keen, he must meet, have a meal, and find a place to discuss and discuss." Lao Wang didn't say this. In terms of strength and appetite, Professor Su would probably lose to him.

Su Rui smiled and said, "There will definitely be a chance."

While everyone was talking, Su Rui took out an instrument from his bag. It looked like a large screen mobile phone. It was very thin and seemed transparent, and it also had a black "protective shell".

Zi Yang said, "I know this thing, I have seen it in science fiction movies. Is it something like a holographic display?"

Su Rui smiled and shook his head, "The holographic three-dimensional display is not useful. This is a miniature life detector." As he said that, he bent his "mobile phone", the screen formed a curved surface and buckled it lightly on his arm.

"This monitor is a bendable screen made of excessive metal sulfide. After being connected to the diving suit, the screen can display your various vital signs, and it can also display the external air environment, temperature, humidity, pressure, and detect radiation, and air composition..."

Lao Wang's eyes were almost glaring out, "So many functions, can this small instrument be realized? Our school's instrument for color ultrasound is as big as a room!" As he said that, he gestured with his hands the size of a room.

Su Rui said, "Decades ago, a computer weighed dozens of tons. Now a smartphone can achieve much more functions than computers in the past. Do you think technological progress is faster?"

Lao Wang said, "That's too fast. If you say this, what's the use of the broken things taught in our books in our school? A waste of time."

Su Rui said seriously: "In fact, the instruments and equipment studied in high-end scientific research are decades ahead of the civilian field, but it is difficult for ordinary people to get in touch with."

After seeing Su Rui’s equipment, Zi Yang sighed in his heart. No wonder Su Rui was so calm in the face of so many difficulties. With these black technologies as the foundation, he really had to feel much more at ease. Sure enough, technology is the primary productivity.

There are only two sets of diving equipment, and now it is a matter of deciding who will go. Of course, the result is no suspense. Xiao Hei and Timur have always been unrelated to him. Among the remaining three, Zi Yang was too lazy to compete with Lao Wang.

However, everything is about fate.

Lao Wang couldn't wear that outfit!

Two sets of diving suits, one is Su Rui's and the other is Alexander's. Su Rui took off his coat generously, revealing the tights inside, his upright breasts, slender and white thighs, and his convex and well-behaved body.

When Zi Yang saw Su Rui take off her clothes, she subconsciously looked elsewhere and thought to herself that this foreign girl was so generous that she didn't care about taking off her clothes.

Lao Wang knew his shame and pretended to cover his eyes with his hands, but his fingers were two inches wide. He stared at them without blinking, and his eyes were about to fall to the ground.

Su Rui put her feet into the diving suit, lifted it gently, and put it on her body obediently, making the outline of her body more firm and sexy. In Lao Wang's words, it is: her legs are protruding in front and have long legs, fair skin, beautiful appearance, thin waist and thin waist.

It was Lao Wang's turn. He tried all his strength to pull the clothes to the base of his thighs, and then lifted them up, and his stomach was strangled. Lao Wang held his breath and shouted, "Hi!" His eyes were bulging, and the clothes would be pulled to the dantian.

Seeing that he worked so hard, Zi Yang shook his head with distress, squatted down and studied Lao Wang's belly. He said to him very seriously, "Even if you excrete more than ten kilograms of waste now, you may not be able to retract your belly."

Lao Wang cursed and complained, "I have a normal stomach, it's just that my stomach has been practicing for many years and my abdominal muscles have developed a little - you said that Alexander is as big as a bamboo pole, why do you look as thin as a bamboo pole?" At this time, he blamed his figure again.

No matter how much he complained, Lao Wang obediently took off his pants and handed them to Zi Yang. Zi Yang looked at Su Rui and blushed embarrassedly. Su Rui turned his head to see him. Zi Yang took off his clothes in a few embarrassingly, only his underwear left, and put on his diving suit in a hurry. Seeing Su Rui covering his mouth there, his shoulders smirking.

Alexander is more than two meters tall, and Zi Yang is more than one meter eight meters tall. Although she looks a little wider, she is generally quite fit.

After Zi Yang put all the equipment on, Su Rui came over to help him seal the diving suit, connected the tube on the oxygen cylinder to the helmet, and hung a equipment belt around his waist.

Zi Yang saw Su Rui lowering his head and working in front of him. Su Rui was 1.7 meters tall and bent down. The hair on his head just tickled his face. He felt itchy and ripples appeared in his heart.

Su Rui was about to connect Zi Yang's helmet and clothes. When he saw his face flushed, he thought there was something wrong with his operation, so he hurriedly asked where he felt uncomfortable. Zi Yang said, "No, I'm not there, I just got angry."

Lao Wang was beside him, but he could see clearly, and muttered in a low voice: "Not the tummy, it's obviously a sperm on the brain!"

After picking up the helmet, a soft light lit up in the mask. Su Rui signaled Zi Yang to speak, and Zi Yang said, "Old Wang is a two-way match." Lao Wang looked at him with no response and looked confused. It seemed that the sealing effect was good.

Su Rui also put on his helmet and made a gesture to Zi Yang. Su Rui's crisp voice sounded in Zi Yang's ears: test, test, ohree.

Zi Yang nodded, indicating that he could hear clearly.

Su Rui told Zi Yang that there is a call system in the two helmets, which can enable real-time conversations.

Su Rui put a curved life detector on Zi Yang's arm, and there were four bulges on the arm of the diving suit, which could be linked to the life detector.

Su Rui clicked on the detector and the screen lit up. Zi Yang felt that the diving suit was different from the hard one he wore just now. It seemed that a gas was flowing in the skin, and the diving suit slowly bulged, gradually getting close to the skin, feeling very comfortable.

Lao Wang looked around and kept tilting his mouth, "Cao, this thing can even shape the body, Xiao Hei, look! Lao Li is quite handsome in this outfit!"

Zi Yang proudly made a Hercules posture. Although he could not hear the sound of talking in the mask outside, there was a sensor on his helmet, and the people inside could still hear the sound outside clearly.

After connecting to the detector, the function of the diving suit was also activated. After a while, rows of numbers and symbols were displayed on the screen. Su Rui roughly introduced several parameters, including heartbeat, pressure, oxygen concentration and other indicators. It is simple and clear, Zi Yang remembers it one by one.

Next, it was time to get into the water. Just as I was about to go down, Lao Wang suddenly grabbed Su Rui's arm and said, "Wait a minute, do you want to tie you with a rope? If there is any situation, I can pull you back."

Su Rui shook his head and said, "No need. If the underwater terrain is complicated and the rope is tied to the rope, it may affect the action and will have a counterproductive effect. Don't worry, the ecological server has powerful functions and there will be basically no accidents, unless there is a special situation... If we don't come back in 3 hours, you can take Alexander back to the entrance of the cave to find a way out."

"No, I'm going to wait for you here." Lao Wang seemed to be crying.

Zi Yang patted his shoulder, "It's okay, we will definitely come back."

Su Rui put on his helmet and held Zi Yang's hand. The two of them slowly walked towards the middle of the pool. Zi Yang looked back and saw that Lao Wang was squatting beside Tan and his eyes were red, as if he was ready to cry at any time. Xiao Hei also looked at him intently. Although there was no expression on his face, he obviously felt a little nervous in his emotions. Even Timur was standing by the pool, looking at them with bright eyes.

This time, it may be a separation of life and death, and Zi Yang suddenly realized.

I have a lot of things in my mind, but I don't know how to say it.

Turning around and waved his hand, the two of them held hands and slowly sank into the pool water. The LED light above the diving suit automatically sensed the brightness around them, slowly illuminating, sprinkling warm light, illuminating the dark blue in front of them.
