Before leaving, Song Jie retreated from the hotel house, Yun Xi looked pity in those stones that were soaked in water for several days, these stones have been soaked for so long, or there is no big change, there is no comparison, there is no harm, after having those stones, Yun Xi didn't want to take this pile of burdens with him at all, after picking for a long time to no avail, this pile of stones resumed their fate of returning to the trash can. Pen, fun, pavilion www. biquge。 info

Yun Xi sighed sadly, patted the small cloth bag hanging on his chest, and threw a bag of stones into the garbage recycling machine with a wave of his hand.

It's really a stark contrast, Song Jie coughed, pretending not to see anything and looking up at the sky.

"I've packed my things, let's go." Yun Xi ran to Song Jie step by step, her things were all bought after coming here, most of them were bits and pieces, all of them were just things that could be packed in a small bag.

Without the help of external tools, the maximum pressure on a person is only 2,000 meters above sea level, and with the help of ordinary external tools, the limit of human pressure is only about 4,000, and compared to the snow top, such a number is undoubtedly not enough.

Song Jie wasn't sure if he would be able to climb to the top of the snow.

led the little girl to the testing place, the entry gate of the northern country was very quiet, it seemed that they came early, there was no one here, the person standing in front of a white building took a mask that could fit the face for Song Jie and Yunxi, and handed the two of them a set of clothes, as well as a small oxygen cylinder. "You go inside, find a locker room to change into, and keep going inside, and the staff will tell you the follow-up."

After the things were divided between the two of them, the man put his hands on the table and continued to nap.

Song Jie didn't have time to ask questions, so he had to pull the little girl inside, find two locker rooms, and quickly change the full set of equipment.

Further inside is a huge field with the roar of a machine, I don't know what is added to this dress, there is a thin layer of inflatable layer, it seems to be very buoyant, and the mask that fits on the face is the same, and Song Jie's whole person has an inexplicable sense of weightlessness, as if it may float up at any time.

Looking at Yun Xi again, he was also shaking his head in a daze.

A man in a yellow plastic suit came up to the two men from a distance, led them to a small room with glass on all sides, and as soon as the door closed, the loud noise was instantly shut out.

Song Jie's ears were still roaring for a while before he came back to his senses, and heard the staff member ask what the highest altitude of their destination was.

"We want to go to the top of the snow." Song Jie's voice was a little loud because his ears were not very good now, and as soon as it reverberated in such a small environment, Yun Xi's ears couldn't recover, and he glared at Song Jie with an eye knife in great anger.

"Can't we bring this equipment with us if we want to go to Snow Peak? I heard them say from the locals that Xueding is a holy mountain, and you can't bring new technology products to it. Song Jie stretched out his hand to stop the person who was about to go out after hearing them finish their destination, and waited for a while, and finally asked the question in his heart after his ears were fully recovered.

The staff member who couldn't see his face clearly behind the plastic protective suit smiled, "Then I don't know, climb the seven-thousand-meter peak without protective gear?" Looking for death, right? ”

"Okay, I'll gradually pressurize it outside in a while, and if you feel uncomfortable during the process, you can press the emergency button next to it, which is the red one on the glass wall, and I will temporarily stop pressurizing and come in to adjust the amount of stampable gas for you." The staff quickly introduced the project to the two of them, and after finishing speaking, he glanced at Yun Xi, and the little girl was only at Song Jie's chest. "She's too young, wearing this device for a long time is not conducive to the growth and shaping of her spine, the test is okay, but I won't give her a northland entry permit."

Although this person's somewhat businesslike tone made Song Jie a little unhappy, what he said made Song Jie breathe a sigh of relief, and he could finally let Yun Xi go home obediently.

It's not at all what was planned, is it?! Yun Xi pouted and sat heavily on the sofa in the center of the glass house.

After explaining to Song Jie what would happen next, the staff withdrew from the glass house, and the figure slowly disappeared from Song Jie's vision.

The little girl sat on the sofa sulking, Song Jie stood for a while before daring to slowly move to Yun Xi and sit down, the little girl didn't even give him a look, she kept staring at one place, not knowing what she was thinking.

Song Jie turned his head at will and looked out of the glass house, except for the tall metal machine in the center of the field, there were small glass houses like the environment in which Song Jie and the little girl were located, and the machines extended many pipes to connect to the roofs of these small glass houses. It was also when he saw the pipes leading to Song Jie that he found that there were two or even higher floors here, except for the vacant place in the center, Song Jie's head turned around and found the stairs upstairs, except for the first floor, the upper floors are just a prominent ring structure, which is used to open such a small glass house, which is located in a circle like a decoration.

The two small pipes wrapped in plastic, one seemed to be gradually pumping out the gas in the room, and the other was injecting gas, Song Jie reached out and tentatively covered the mouth of the pipe, and came to several conclusions.

The red number on the display finally jumped to four thousand. This change is really slow, from the starting altitude of more than a thousand plateaus, it has just increased to four thousand in more than half an hour, Song Jie yawned boredly.

To be honest, it may be because of this dress, the altitude of four thousand has made him feel more comfortable, and the inexplicable feeling of weightlessness has finally disappeared, and Song Jie stretched his waist to prevent himself from falling asleep.

"Yunxi, are you okay?" Song Jie patted the little girl who didn't pay attention to him for a long time, and sure enough, he received a pair of silent eyes. "When I didn't say anything."

This girl is almost the same as him in the race, how can there be something wrong with sitting for a while, just kidding?

After staying for nearly half an hour, the air pressure detection index has risen to the state that 6,000 meters above sea level will have. Song Jie felt that he was gradually becoming a little depressed, his body was like being tied with a brick, and a small movement took a lot of effort, Song Jie gradually heard Yun Xi's suppressed breathing sound turn into a big gulp of non-stop panting, and hurriedly pressed the button on the glass wall.

But it wasn't what he imagined that the instrument would stop when he pressed the button, Song Jie found that the air pressure indicator on the display screen was still slowly increasing, and he suddenly became a little anxious.

Song Jie's eyes looked around, reaching out to pull the handle on the glass door but to no avail, as soon as the pressure started, the door had been locked from the outside, and he looked outside for a long time and couldn't find the figure in yellow plastic overalls. Yun Xi's breathing became more and more rapid, and Song Jie, who was anxiously looking for a way, inadvertently swept his gaze over the small oxygen cylinder that he placed on the ground after entering the door, no wonder.

As if grasping a life-saving straw, Song Jie quickly picked up the oxygen cylinder, unwrapped the mask attached to the tube, and put it on Yun Xi's face.

Yun Xi, who had been panting for breath with his eyes closed, finally calmed down after a burst of tight breathing, and the fists that had been clenched slowly relaxed.

The pressure continued to increase, and the oxygen in the small oxygen cylinder could only supply a person to breathe for more than ten minutes, and Song Jie kept clapping the red emergency button anxiously.

The number that kept beating up finally stopped at six thousand one hundred, and Song Jie saw a figure in blue plastic overalls running from afar.

To his surprise, the person did not open the door, but directly entered the room through the glass, and his entry did not change the air pressure inside the room, ensuring that Song Jie could continue the test for a while.

"I'm sorry, I'm sorry, it's shift time, and the last one forgot to tell me that there are still people here doing tests." The first thing the man in blue did as soon as he came in was to bow to Song Jie all the time, sorry.

Even if Song Jie was very angry, he was embarrassed to say anything more, but the emergency props here were quite complete, and he was given a small oxygen cylinder, probably to prevent such an emergency. You can't scold him, can you? Nothing can be changed, Song Jie ignored his hypocritical apology, "Help me see what's wrong with her." ”

Song Jie slowly helped Yun Xi who was lying on the sofa to sit up.

That person looked at Yun Xi, who was obviously one size smaller than the protective suit, and his face was a little unbearable, what a big mess did the previous goods leave for themselves?!

"I'm sorry, according to our safety rules here, a child of her age can't be tested for a pressure test, this may be the negligence of our safety officer, not caused by damage to her clothing, she can't stay here to continue the test."

"Security officer?" Song Jie carefully recalled the person sleeping on the table at the door. He was pretty sure it was the only person he had seen other than the yellow plastic suit.

"Yes. Our safety officers check the testers' information and distribute protective gear. The staff member quickly helped Song Jie recall, "Do you still need to continue the test?" I looked at a glass house, and the upper limit of the air pressure was 7,150 above sea level. ”

"I'm going to continue testing, but how can you take her out?" Song Jie pointed at the little girl with an embarrassed face, she didn't know how to penetrate the wall.

"This is not a wall penetration, the molecules are exclusive, this room is not ordinary glass, you don't have to worry." As he spoke, he pulled out a folded piece of blue cloth from his waist and wrapped the little girl in its entirety.

The person directly hugged the little girl and walked out through the glass, Song Jie looked carefully this time, it was not so much a wall-piercing technique, but a momentary integration.

The altitude shown on the display began to beat again, and it looked like he would have to sit here for half an hour......
