Butterfly dream life

Yu Xiaoduo waited on the platform for a while, and Gu Haiya came.

Gu Haiya wore a pure black diving suit, which looked a bit like work clothes, with valves and several pockets on his body, a pair of black rubber diving boots on his feet, and a special forces hood covering his entire head, Connected to the neck, only a face was exposed.

Yu Xiaoduo looked him up and down, thinking that only Gu Haiya could hold this kind of headgear, if it was worn by an ordinary-looking person, it would be so ugly!

"Hai Ya, your suit looks so cool!" Yu Xiaoduo said, "It's even cooler than the one you play in the game. I want to wear it too, but unfortunately there is no such equipment option in the game."

Gu Haiya stood by the table arranging his things and said, "This is a dry suit. After you get promoted to A, you can buy a set if you are interested."

"Okay." Yu Xiaoduo said casually, "I'll buy a set to wear when the time comes, how much is it?"

Gu Haiya: "The cheapest one is more than 1."

"So expensive?" Yu Xiaoduo said in disbelief.

"Professional ones cost tens of thousands of dollars." Gu Haiya said, "They all need to be customized."

"Oh..." Yu Xiaoduo nodded, and changed his words: "Then I'd better think about it."

Gu Haiya: "..."

"How much do you weigh?" Gu Haiya walked up to Yu Xiaoduo, carrying a belt and a lead weight.

Yu Xiaoduo replied: "I weigh 62 kilograms."

After thinking for a while, Gu Haiya started to make the weight belt.

"What is this for?" Yu Xiaoduo asked.

"The human body itself has buoyancy." Gu Haiya explained, "Combined with equipment and gas cylinders, it is difficult to sink without wearing weights. Weights not only allow you to dive quickly, but also prevent you from floating. It will be very dangerous if you float up, especially in deep water.”

"With the wind……?"

Yu Xiaoduo subconsciously created a picture in his brain, he was like a seaweed, floating softly in the water, at the same time, a dynamic melody sounded in his mind.

"Like a seaweed, seaweed, seaweed, seaweed, drifting with the waves, seaweed, seaweed, seaweed, dancing in the waves..."

Yu Xiaoduo: "..."

[Jobs...] Yu Xiaoduo's mouth twitched.

[Isn't it nice? 】Jobs said, 【This is one of the top ten Internet hits of last year, and I think it fits the occasion. 】

【thank you. 】Yu Xiaoduo said speechlessly, 【Can you please turn it off? 】

The music stopped abruptly, and Yu Xiaoduo secretly breathed a sigh of relief, complaining about Jobs' nonsensical behavior from the bottom of his heart.

"Gone with the wind, it means that you are underwater..." Gu Haiya said while looking at Yu Xiaoduo, seeing that his eyes were straightened, as if he didn't seem to be listening to him, so he shouted: "Xiaoduo, Xiaoduo?"

"Ah? Oh!" Yu Xiaoduo came back to his senses and asked, "What did you say just now? Gone with the wind?"

"Floating means that you float up suddenly underwater." Gu Haiya said patiently, "If you are in a shallow water area of ​​five meters, it is easy to cause accidents when you float up suddenly."

"Accident..." Yu Xiaoduo looked blank, "For example?"

"For example, there are many ships passing by in open waters, and the speed is very fast. If a diver suddenly emerges from the water surface, in case a ship passes by, just 'snap' and it will be over."

As he said that, Gu Haiya made a knife-cutting gesture on his head, and then asked: "Do you understand?"

Yu Xiaoduo was startled, and Jobs immediately thoughtfully played the animation demonstration in his mind.

In an instant, the watermelons were flying all over the sky, the sharp blades were unsheathed, and the cold light was shining. Accompanied by the dubbing of "咻咻咻", all the watermelons were cut into pieces in an instant, and the bright red juice splashed everywhere.

"Okay, so scary..." Yu Xiaoduo turned pale.

"Don't be afraid." Gu Haiya reassured, "As long as you follow the rules and strictly follow the steps, this kind of accident can be completely avoided."

Yu Xiaoduo was relieved, but Gu Haiya said: "Our focus is to prevent floating in deep water, this is the fatal danger."

"Lethal..." Yu Xiaoduo's face suddenly turned from white to green, and he asked in horror, "Why? Will it explode?"

"It wasn't an explosion." Gu Haiya didn't know whether to laugh or cry, and said, "If you float up suddenly in deep water, you will get decompression sickness."

"Decompression sickness?"

"It's a diving disease." Gu Haiya said, "Because of the high pressure in the deep water area, the nitrogen in the cylinder will be forced to dissolve into the blood in the body. An air embolism can form in the air, which can be life-threatening.”

"It's so scary!" Yu Xiaoduo screamed, "Isn't diving a high-risk sport? I...is it too late to repent now?"

"It's too late." Gu Haiya said solemnly, "If you get on my pirate ship, don't even think about going down."

Yu Xiaoduo: "..."

"Stand still." Gu Haiya said, "I'll help you fasten the weight belt."

Yu Xiaoduo got up, Gu Haiya put the weight belt around behind him, and then around in front of him, and fastened it carefully. During the whole process, their lips were very close to each other from time to time, as if they were hugging and kissing. Yu Xiaoduo was both shy and nervous. Embarrassed, and at the same time feel myself reacting again.

He secretly pulled down his pants, fortunately Gu Haiya didn't notice, fastened the weight belt carefully, and picked up a heavy waistcoat.

"This is called a BCD." Gu Haiya said, "There are airbags inside, and this device can be used to inflate and deflate air."

Gu Haiya demonstrated how to operate, and Yu Xiaoduo nodded, indicating that he understood.

"This is called a regulator." Gu Haiya took out the breathing device and continued to introduce: "This is the first stage, this is the second stage, this is the spare second stage, and this is the pressure gauge."

"The first stage is connected to the gas cylinder." Gu Haiya twisted the first stage toward the gas cylinder, and said, "The second stage and the spare second stage are for breathing, just bite the mouthpiece on it, and the pressure gauge is for breathing." Let’s check the air volume in the bottle, when the air pressure drops to [-] Bar, it must come out of the water.”

Yu Xiaoduo stood by the side stupidly, listening in a fog, and could only nod his head non-stop.

"If you sink too fast, add some gas, so that you can float up." Gu Haiya added, "If you want to sink, you can deflate, but don't refill and deflate frequently, otherwise your gas cylinder will be exhausted early. "

"What will happen if it runs out?" Yu Xiaoduo almost fainted, remembering the back and forgetting the front.

"When you run out, you have to go up and finish the dive." Gu Haiya fixed the gas cylinder and ordered, "Sit on the first step and help you put on the BCD and carry the gas cylinder."

"It's over when it's over." Yu Xiaoduo sat down and asked puzzledly, "Can't I get out of the water early?"

"Yes, yes." Gu Haiya helped him put on the BCD and adjusted the two breathing tubes, and said, "But diving is a team sport. You can't go into the water alone. You must have a Buddy. If you run out of air early on by yourself, all People have to follow the water, and after a few times, no one wants to play with you."

"Buddy?" Yu Xiaoduo was carrying a heavy cylinder, and was thrown backwards.

"Well, Buddy." Gu Haiya hugged him to sit firmly, and said: "The underwater situation is very complicated, and it is very dangerous to go down alone, so the open water diving regulations require no less than two people to go into the water at a time. , and each other should take care of each other."

"Then when I get promoted to A, can you be my Buddy?"

"I'm usually in class, how can I have time to play with you? How can I be your Buddy?"

Yu Xiaoduo sighed in disappointment and stopped talking. Gu Haiya glanced at him and said, "But if there is a chance to go diving with you, I can be your buddy."

"Keep your word!"

"Okay, count."

Yu Xiaoduo revived with full blood in an instant, Gu Haiya took his diving goggles, walked to the table, squeezed some shower gel on the lenses, wiped it evenly, and then put it into the large bucket filled with water to wash it off.

"What is this for?" Yu Xiaoduo asked strangely.

"Because of the temperature difference, the mask will fog up underwater." Gu Haiya explained, "It is not easy to fog up after this treatment, but this is not the most effective."

"Huh?" Yu Xiaoduo asked curiously, "How else can I do it?"

Gu Haiya picked up his diving goggles, licked the two lenses with his tongue, and said, "Saliva works best."

Yu Xiaoduo: "..."

Seeing Gu Haiya's red tongue, Yu Xiaoduo's face became hot, and he stammered: "Yes, a little..."

"It's kind of disgusting, isn't it?" Gu Haiya walked over, and said with a smile, "It's not disgusting if you lick it yourself, do you still despise your own saliva?"

"No, it's not disgusting." Yu Xiaoduo said heartily that I wouldn't mind if you licked me.

Gu Haiya handed him the diving goggle, and said: "If the mask gets in water, you can drain it like this." After finishing speaking, he held down the diving goggle, raised his head, exhaled forcefully through his nose, and then said: "Air is stronger than liquid. Be gentle, the exhaled air will squeeze out the water in the mask, remember to look up.”

Yu Xiaoduo did it several times, and Gu Haiya said: "The next thing I say is very important, it is about the balance of ear pressure, you must listen clearly."

"Ear pressure balance?"

"Did your ears feel blocked when you were flying?"

"Yes, I have."

"It's the same underwater." Gu Haiya said, "The pressure underwater is high. If you don't balance the ear pressure, the pressure difference between the inside and outside of the head cavity will cause eardrum pain."

"Then what should we do?" Yu Xiaoduo asked.

Gu Haiya demonstrated how to do ear pressure balance, and then guided Yu Xiaoduo to practice. Yu Xiaoduo learned a little bit of knowledge, and after a long time he barely understood the principle, but he hadn't entered the water yet, so he didn't know if he had learned it or not.

"Remember this gesture, it's important, it means 'there's a problem.'"

Said Gu Haiya turned his right hand into a palm, turned it up and down, and said: "If you feel uncomfortable or something is wrong, just make this gesture to me immediately, and I will help you solve it, or take you out of the water directly.

Yu Xiaoduo said he remembered it, and Gu Haiya taught him a few simple diving sign language, and finally said: "Learn these first, and I will teach you more after the formal examination. Now put on the flippers and let's go into the water."

After entering the water, Gu Haiya took Yu Xiaoduo more than ten meters away from the platform. Yu Xiaoduo began to get scared, and with the water temperature less than [-] degrees, he shivered uncontrollably.

[Don't be afraid, I will protect you. 】

"Don't be afraid, I am here, and I will protect you."

The voices of Jobs and Gu Haiya sounded at the same time, Yu Xiaoduo became less nervous and let out a deep breath.

Gu Haiya hugged Yu Xiaoduo from behind, wrapped his arms around his waist, held up the exhaust valve of the BCD with the other hand, and said softly: "Trust me, let's dive now, shall we?"

"Okay!" Yu Xiaoduo turned his head, his lips almost pressed against Gu Haiya's face, and said seriously: "I believe in you, Haiya."

Gu Haiya stared at him for a moment, nodded slightly, pressed the valve, and the two of them bit the breathing tube each, with bubbles rising and sinking into the sea.

During the dive, Yu Xiaoduo tried his best to balance the ear pressure, but he didn't know what was wrong, he failed, as if there were thousands of steel needles piercing in his ears, and the severe pain suddenly hit.

【Oh my God--! 】Yu Xiaoduo yelled in his head, 【Jobs!Help!It hurts me to death! 】

Jobs: [007...I...wait...]

Yu Xiaoduo: [? ? 】

Jobs' speech became staccato, accompanied by the sound of electric current, like a damp old radio.

[Jobs? 】Yu Xiaoduo endured the pain and asked: 【What's wrong with you?What's the matter? 】

【007...I...】

Jobs' voice was still very stuttering, and Yu Xiaoduo was still sinking, his head was about to explode with pain. After a few seconds, there was a buzzing in his head, and then there was no movement at all.

Yu Xiaoduo: "........."

Did you make a mistake?!Yu Xiaoduo was about to cry, thinking why this broken AI crashed again, and her ears hurt... What should I do?How about I go up?But it didn't even take a minute to get into the water...wouldn't it be too useless?Haiya will look down on me, right?

Driven by self-esteem, Yu Xiaoduo had no choice but to continue to balance the ear pressure, and gritted his teeth, enduring the severe pain caused by the strong water pressure.

At a depth of five meters underwater, there is a wooden platform about ten square meters.

Gu Haiya took Yu Xiaoduo down to the platform, first knelt down on both knees, then bent his two fingers in the middle of the food, and made a gesture of kneeling to him, Yu Xiaoduo forced himself to kneel down too.

The two knelt face to face, like a couple praying to heaven and earth, Gu Haiya made an OK gesture, and asked silently: 【Are you okay? 】

[OK. 】Yu Xiaoduo gestured against his will.

Gu Haiya pointed to his ear, gestured and asked: [Is the ear pressure OK? 】

Yu Xiaoduo was in so much pain that tears were about to burst out, but he still held back his reply: 【OK. 】

Gu Haiya tilted his head slightly, watched him carefully for a while, then pointed to his ear, flipped his palm over, and asked silently: 【Ear pressure, is there a problem? 】

Seeing this gesture, Yu Xiaoduo finally couldn't bear it any longer, nodded to Gu Haiya aggrievedly, and waved his hands wildly at the same time, Gu Haiya immediately grabbed his inflation valve, added a few times of air, and brought him to the surface of the sea quickly .

"How is it, Xiaoduo?" Gu Haiya helped him take off the diving goggles, hung them around his neck, and asked nervously, "Does your ears hurt? Do you want to go ashore to rest?"

Yu Xiaoduo looked at Gu Haiya with tears in his eyes, and said pitifully, "Hai Ya, my ears hurt so much, I did what you said, but it didn't work..."

"It's okay, just try a few more times." Gu Haiya reassured, "Shall I take you ashore for a meeting? Or float here for a rest?"

"It's too troublesome not to go ashore." Yu Xiaoduo shook his head and said, "Just float, let me take it easy."

Gu Haiya hummed, and floated on the sea with Yu Xiaoduo in his arms.

Not long after, Yu Xiaoduo felt much better, so Gu Haiya repeatedly taught him to do ear pressure balance, and after Yu Xiaoduo fully mastered it, he took him to dive to the underwater platform again.

They knelt down on the platform, Gu Haiya held Yu Xiaoduo's hands, checked his reaction carefully, and after confirming that everything was normal, he gestured and asked silently: 【Are you okay? 】

This time Yu Xiaoduo did it very successfully, and there was no needling in his ears anymore, so he responded with gestures and nodded vigorously: 【OK! OK! 】

Gu Haiya smiled.

Even though the underwater visibility is not high, they are very close at the moment, so Yu Xiaoduo can still clearly see Gu Haiya's warm and handsome smile.

Under the water, I can't hear any noise from the hustle and bustle, only the sound of exhaust gas, as well as my own breathing and heartbeat.

In the silent world, at the moment when Gu Haiya smiled, Yu Xiaoduo had an illusion, as if there were only two of them left in the world, and immediately felt the urge to hug each other tightly.

However, he simply smiled back at Gu Haiya.
