In the face of the excitement of the whale, Li Xinian seems to be a lot calmer. Although his expression is still light, from the perspective of keeping a close eye on the parameters, it can be seen that his heart is not as calm as his expression.

Hypoxia can cause headache, general fatigue, walking difficulties, panic, shortness of breath, chest tightness, pulmonary edema, and even serious loss of life. Whether at high altitude or underwater, hypoxia is a problem that human beings have been unable to overcome since ancient times.

But "frogman" mostly carries out tasks underwater, and soldiers play a very important role in the selection of anti hypoxia time, and even decide to go or stay.

Li Xunian stared at the rising value, looked at the time calmly, there was dark light in the cold eyes gradually gathered, finally converged into a bright light like a winter night to light up the whole cold night.

"Fast, fast, fast!" Big whale didn't notice his change. He stared at the screen closely and looked nervous as if he was conducting a selection test.

At the set time, the first hint of "drip" was sent out. The whale was so excited that he wanted to jump out of the chair, or Li Xinian, who was standing behind him, raised his hand and pressed his shoulder. This did not lose his temper.

"Five minutes, demon! She did it! It's not red The whale was a little excited as he found the treasure, and his eyes were shining, as if a light burst out, "more than the soldiers we left behind!"

Good, five minutes have passed!

As the great whale said, she did surpass the twenty-four soldiers left behind!

"The value began to rise and the instrument was removed." Li Xinian's expression didn't change at all, but when he held the table with one hand, his long fingers tightened slightly. "Give me the results after the high-2 reaction test. Keep a close eye on them. The value just turned off the instrument immediately."

Seeing that the captain who was younger than himself was still calm, big whale realized that he had lost his temper. He cleared his throat and whispered, "it's hard to meet a man who can endure hypoxia for five minutes at a time. I'm sure I'll be careful!"

As the instruments on the arm were removed, Ye Jian, who was liberated from the upper limbs, felt the blood "locked" all over the arm. It seemed that the heaviness of the separation between the upper limbs and the lower limbs disappeared in a moment.

Take the lower mask, the crimson leaf Jane didn't immediately open her mouth to breathe, her lips slightly tooted, slowly, rhythmically, deep breathing, and then let her body slowly relax with the breath.

Five minutes of anoxia is like walking through a ghost gate. The sweat on the back is still pouring. The sweat on the front of the forehead is converging into a trickle, dropping down the chin to the front of the dress.

The chimaera, who had been guarding for a long time, took a deep breath in the dark, and then broke the silence of the room Although the voice is light, it has obvious ups and downs. It can be seen that the chimaera is also a little excited at this time.

Five minutes! A qualified frogman's hypoxia training is five minutes. Can he not be excited?

But I soon woke up and got excited again She also belongs to the army.

Ye Jian had a few moments in her mind. Hearing this, she said with a smile, "my arm is tied to the instrument. Otherwise, I can reach six minutes. Six minutes is my limit."

When Chen school was training at the seaside, she could hold her breath for only two minutes at first. Later, when she went to the plateau for training, Uncle Chen asked her to wear a mask for morning exercise, wear a mask and go to the plateau lake. Even when she went to sleep, she was required to wear a mask, which made her achieve the present results.
