Li Jinnian seemed much calmer in the face of the big whale. Although his expression was still faint, from the perspective of his eyes that were closely watching the values ​​of various parameters, it was somewhat obvious that his heart was not as calm as his expression.

Hypoxia can cause headaches, general fatigue, difficulty walking, palpitations, shortness of breath, chest tightness, pulmonary edema, and even life may be lost in severe cases. Whether it is a plateau or underwater, hypoxia is a difficult problem that humans have been unable to overcome from ancient times to the present.

The "frogman" mostly performs tasks underwater. In the selection competition, soldiers play an extremely important role in the length of time to resist hypoxia, and can even decide to go or stay.

Li Jinnian stared at the rising numbers and looked at the time calmly. A dark light gradually condensed in his cold eyes, and finally formed a stream of light that was as bright as a winter night, as if it lit up the whole cold night.

"It's soon, it's soon, it's soon!" Da Jing didn't notice his changes, stared at the display screen, and looked so nervous that he seemed to be conducting a selection test.

The first "drip" prompt was issued at the set time. The big whale was so excited that she wanted to jump out of the chair. Li Jinnian, who was still standing behind him, raised her hand and pressed his shoulder, so she did not lose her composure.

"Five minutes, Demon King! She did it! The value has not turned red yet!" The big whale said excitedly as if it was discovered a treasure, with a bright look in her eyes, as if a light burst out, "It's more than the soldiers we left behind!"

Very good, five minutes have passed!

As Da Jing said, she indeed surpassed the twenty-four soldiers who remained!

"The value began 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. "After the high co2 reaction test, give me the results, keep a close eye, the value just soared and turned off the instrument immediately."

Seeing that the captain who was younger than him was still calm, Da Jing realized that he was a little out of control, he cleared his throat and whispered: "It's rare to encounter someone that can last for five minutes at once, so I will definitely be careful!"

As the instruments on the arm were removed, Ye Jian, who was liberated with his upper limbs, suddenly felt that the blood that was "locked" was pouring into his arms. The feeling of heavy feeling of being pressed on his left and right shoulders, and it seemed that the upper limbs and lower limbs were separated instantly.

Taking off the mask, Ye Jian, whose face was as red as the clouds, immediately opened his mouth and breathed heavily. His delicate lips were slightly pleated, and he took a deep breath with a rhythm, and then let his whole body relax in and out in and out of the breathing.

Five minutes of hypoxia is like walking from the gate of hell. Sweat on your back is still experiencing a lot of drops. The sweat on your forehead gathers into a stream, dripping along your chin to the mouth of your clothes.

Daxiu, who had been guarding, took a deep breath in the dark for a while before breaking the silence of the room. "The results are good, five minutes and twenty-four seconds." Although the voice was light, there were obvious ups and downs, which showed that Daxiu was also a little excited at this time.

Five minutes! A qualified frogman trains to withstand hypoxia for five minutes. Can he not be excited?

But she woke up quickly and was excited again... She also belonged to the Army.

Ye Jian had been thinking about the time, and when he heard this, he smiled and said, "If you tie the instrument on your arm, you can reach six minutes. Six minutes is my limit."

When she was training by the beach with Chen School, she could only hold her breath for two minutes at first. Later, when she went to the plateau training, Uncle Chen asked her to wear a mask for morning exercise and went down to the plateau lake with a mask. Even when she was sleeping, she asked her to wear a mask, which made her current results.
