Chapter 1260: Shocked to the Point That Their Jaws Dropped

Six minutes was Ye Jian’s limit. However, to many people, they would have already lost their life.

Big Shark heaved a long sigh in his heart again. He then focused on the second test. No matter how powerful she was, she wouldn’t belong to the navy or the Storm Commando Brigade.

However, it was exciting for a female soldier to surpa.s.s a male soldier. It didn’t matter whatever unit she belonged to.

Ye Jian didn’t know that Big Shark’s heart was churning. She walked out of the testing room and quickly adjusted her body’s condition to enter the high C02 adaptive test.

This was a training that the frogmen had to learn, and one that the members of the Storm Commando Brigade had to take.

“This is the form for our CO2 endurance training. Take a look at it.” The voice of Big Shark, who had accompanied and recorded the entire process, sounded slightly restrained. Standing in the clear water, he said to Ye Jian, who was already prepared, “The interval time will decrease to 15 seconds, the time to hold your breath will remain the same. We have 30 minutes of testing. You might feel a little uncomfortable, and you might even vomit.”

“There’s a coral archipelago below. You need to dive to its bottom. The bottom is about 15 meters away from the sea surface. Remember, Ye Jian, we need to record your best personal score and your worst score. Within 30 minutes, I need to see if your average score will pa.s.s.”

The high CO2 was a dangerous test. They had to dive in the water without any source of air. When Ye Jian entered the sea after taking a breath, she closed her eyes and kept swimming like a fish.

The oxygen content in her blood started getting lower. The high concentration of carbon dioxide caused her body to feel uncomfortable. Her twitching diaphragm told Ye Jian that she needed to breathe. She needed to get out of the water to get oxygen.

Relax, relax. Your body must relax. Don’t let your body and your mind become afraid of the increasing content of the CO2 in your body. Listen to the sound of the water and feel the joy of the fishes swimming past you. Don’t let fear and other factors interfere with you. Ye Jian only quickly surfaced when she reached her limit.

“Don’t take too long to rest. If not, the CO2 that you worked so hard to acc.u.mulate will be expelled out of your body because of the long rest time. You won’t be able to reach the goal of acc.u.mulating a high C02. Once you surface for more than 30 seconds, the c.u.mulative effect of CO2 will be very bad. Ye Jian, you need to control your breath and enter the sea again within 20 seconds.”

Big Shark’s strict voice kept reminding Ye Jian. Holding the timer in one hand, he waited for Ye Jian to regulate her breathing and dive into the sea again. His expression turned more serious.

20 seconds of breathing was harsh for a new recruit. However, he did want to know if Ye Jian could surpa.s.s a recruit and took the risk of letting her regulate breathing for 20 seconds.

For new recruits, the risk of changing their breath in 20 seconds was a little high, but for the Storm Commando Brigade, it was too long.

During the entire breathing process, the air in the lungs would be exchanged with each breath. The frogmen would rest for 15 seconds before entering the next round of high CO2. Giving Ye Jian five more seconds, was the time Big Shark reached after rounds of tests before deciding that it was feasible and conservative.

She dived 15 meters into the sea in one breath. After holding her breath for two minutes, Ye Jian rushed up again and rested for 15 seconds. This cycle continued for 30 minutes. After the entire test ended, even Ye Jian, who had been enduring hards.h.i.+ps, felt as though all her energy had been sucked out.

Big Shark looked at the wet female soldier who was able to remain proud even when she was tired. Then, he looked at the records on the form. His Adam’s apple moved up and down a few times… This record was enough to shock his comrades.
