In the face of the excitement of the big whale, Li Jinnian seemed much calmer, although his expression was still faint, but from the gaze of staring at the values of various parameters, it could be seen that his heart was not as calm as his expression.

Hypoxia can cause headaches, general fatigue, difficulty walking, palpitation, shortness of breath, chest tightness, pulmonary edema, and even loss of life in severe cases.

The "frogmen" mostly perform tasks underwater, and the soldiers in the selection competition play an extremely important role in the length of time they tolerate hypoxia, and can even decide whether to go or stay.

Li Jinnian stared at the gradually rising value, calmly glanced at the time, and the dark light in his cold eyes gradually condensed, and finally converged into an extremely bright streamer like a winter night, so bright that it seemed to light up the entire cold night.

"Hurry, hurry, hurry!" The whale didn't notice the change in him, his eyes glued to the monitor, his expression nervous as if he was conducting a selection test.

The first "drop" prompt was issued at the set time, and the big whale was so excited that he wanted to jump out of the chair, but Li Jinnian, who was still standing behind him, raised his hand and pressed his shoulder, so he didn't lose his temper.

"Five minutes, Demon King! And she did! The values haven't soared yet! The big whale said excitedly as if he had discovered a treasure, his eyes shining as if a light had burst out, "More than the soldiers we left behind!" ”

Well, five minutes have passed!

As the whale said, she did surpass the twenty-four soldiers who remained!

"The numbers started to rise, and the instrument was removed." Li Jinnian's expression did not change at all, but when he supported the table with one hand, his slender fingers tightened slightly, "Give me the results after the high CO2 reaction test, keep an eye on it, and the value is just red, and immediately turn off the instrument." ”

Seeing that the captain, who was younger than himself, was still calm, the big whale realized that he was a little out of shape, he cleared his throat and said in a low voice: "It's rare to meet a person who can tolerate hypoxia for five minutes at once, I will definitely be careful!" ”

With the removal of the instrument on his arm, Ye Jian, whose upper limbs were liberated, suddenly felt that all the blood that was "locked" rushed to his arms, and the heaviness that seemed to press several mountains on the left and right shoulders, and as if the upper limbs and lower limbs were separated disappeared instantly.

Taking off the mask, Ye Jian, whose face was as red as a glow, did not immediately open his mouth to breathe, his delicate lips pursed slightly, slowly and rhythmically took a deep breath, and then let the whole body slowly relax with the breathing in and out.

Five minutes of lack of oxygen is like walking out of the ghost gate, the sweat on the back is still dripping in big drops, and the sweat on the forehead gathers into a trickle, dripping down the chin to the placket.

The big shark who had been guarding it secretly took a deep breath for a while before breaking the silence of the room, "The results are good, five minutes and twenty-four seconds." Although the voice is soft, there are obvious ups and downs, which shows that the big shark at this time is also a little excited.

Five minutes! A qualified frogman can not get excited if he is trained for five minutes to withstand hypoxia?

But he soon came to his senses and became excited...... She also belongs to the Army.

Ye Jian has been counting the time in his heart, and when he heard the words, he smiled and said: "I have an instrument tied to my arm, otherwise it can be six minutes, and six minutes is my limit." ”

When she trained at the beach with Principal Chen, she could only hold her breath for two minutes at first, but when she went to the plateau for training, Uncle Chen asked her to wear a mask for morning exercises, and went down to the plateau lake with a mask, and even asked her to wear a mask when she went to sleep, which led to her current results.
