Six minutes was Ye Chien's limit, but for many people, six minutes of lack of oxygen underwater was enough to kill them.
Big Mermaid sighed deeply in her heart again, then she focused on the second test. No matter how good she was, she would not belong to the Navy, nor would she belong to the Storm Commandos.
However, if a female soldier could surpass a male soldier, whether she belonged to her own unit or not, it was still something to be excited about.
Ye Jian did not know that the Great Mermaid's heart was in turmoil. She walked out of the testing room and quickly adjusted her body to enter the high C02 tolerance and adaptation test.
This was a compulsory training for the frogmen, and also one of the tests for the Storm Commandos.
"This is our C02 tolerance training form, take a look." Big Mermaid, who accompanied and recorded the whole process, stood in the clear water and said to Ye Chien, who was already prepared, "Your breathing time will decrease by 15 seconds, but the time you can hold your breath will remain the same. We have 30 minutes of testing, you may feel a little uncomfortable, and you may even experience nausea and vomiting. "
"There is a coral archipelago below, you need to dive to the bottom of it, which is about 15 meters from the surface. Remember, Ye Chien, we need to record your best personal score and your worst score. In 30 minutes, I want to know if your average score is passing. "
High CO2 was a dangerous test for diving underwater without any air source. When Ye Chien held her breath and dove to the bottom of the sea, she closed her eyes and kept her breathing tight, swimming like a fish to the bottom of the sea.
The oxygen content in her blood began to decrease, and the high concentration of CO2 gradually made her body uncomfortable. Her diaphragm muscles began to twitch, telling Ye Chien that she needed to breathe, needed to rise to the surface to get oxygen.
Relax, relax, the body must relax, let the body and mind not be afraid of the gradually increasing CO2 content in the body, listen to the sound of the water, feel the joy of the fish swimming by, and avoid being disturbed by fear and other factors. When the oxygen content in her blood reached the limit, Ye Chien quickly rose to the surface.
"Don't rest for too long, otherwise the C02 accumulated will be expelled from the body because of the long rest, and you won't be able to accumulate high C02. Once you float to the surface for more than 30 seconds, the cumulative effect of C02 will be very bad. Ye Chien, you need to take a breath within 20 seconds and dive back into the sea. "
Big Mermaid's strict voice kept reminding Ye Chien. He held a timer in one hand, waiting for Ye Chien to take a breath and dive back into the sea, and his expression would become more serious.
20 seconds for breath was actually quite harsh for a recruit, but he really wanted to know if Ye Chien could surpass a recruit, so he took the risk of taking a breath in 20 seconds.
To the recruits, taking a breath in 20 seconds was a little dangerous, but to the Storm Commandos, taking a breath in 20 seconds was a long time.
During the whole breathing process, every breath would exchange the air in the lungs. The frogmen rested for 15 seconds and immediately entered the next round of high C02. Giving Ye Chien an extra 5 seconds was what Big Mermaid finally found to be feasible and conservative after a few rounds of testing.
Ye Chien dived 15 meters into the sea in one breath, held his breath for 2 minutes, and then rushed back up to rest for 15 seconds. This cycle continued for 30 minutes, and when the entire test was over, even the hardworking Ye Chien felt as if all the energy in his body had been sucked out.
Big Mermaid looked at the female soldier who was completely drenched, but still maintained the pride of a soldier, and then looked at the record on the form. His Adam's apple lightly moved up and down a few times …. This kind of record was enough to make their comrades' jaws drop.
