He swung his limbs naturally and gracefully along the pre-set rope, swimming forward rhythmically and plannedly, the light shining into the water through the hole opening, refracting at a distance of tens of meters around, and the underwater scenery was breathtaking. Steig's figure disappeared into the dim area under the ice, and soon entered the next bright cave entrance, so that the 7 holes were left behind by him, his figure appeared at the last exit terminal, 2 minutes and 11 seconds under the cold ice water, swam a distance of 500 feet, he naturally surfaced, greeted the onlookers, the people on the ice began to cheer and applaud him, congratulations and joy for his success, the Guinness World recorder made a strong note for him, and his name and challenge data have since become the object of people's talk。 Shang Minjie smiled.

"Take a sip of porridge and moisten your throat. Fat Yin took another bowl of pumpkin porridge and handed it to Shang Minjie.

"Brother, how can you drink porridge to moisten your throat, you are so wonderful. Yin Yuting gave him a blank look.

Shang Minjie looked at Yin Fat Man and smiled, lowered his head and took a sip of porridge, and continued: "I asked Steig how he felt during the underwater challenge, and he said: Once you dive into the icy water, it is like entering another realm, as the consumption of oxygen in the body becomes less and less, the body and brain strongly require me to breathe, and I need to discharge carbon dioxide and other toxic gases from the body, but I need to control my brain and body physiology, and the control process is also a painful process. After surviving this difficult stage, my body began to become relaxed and comfortable, just like integrating my body into nature, and the cold water became a whole, at this time I need a clear consciousness, a strong will to control my body, forward to make the most scientific and reasonable movements, so that the consumption of the body to the minimum. When there is a sharp lack of oxygen in the body, it is necessary for my body to enter a deeper state of relaxation, at this time, I will deeply feel the beauty of nature and my body closely integrated, those colorful and beautiful scenery appear in the brain, so that I am unwilling to leave for this and insist on my best state, to this level has actually entered the edge of life and death, many people are because of entering this realm and lost consciousness and died. The final stage of the dive is the so-called death edge stage, which is the struggle stage, when my ears hear sounds, such as the sound of metal hitting, the color in front of me disappears, and it becomes black and white, because the oxygen supply is severely insufficient, the nervous system will be disturbed, causing me to have delusions, so at this time I have to surface. ”

Wu Lang took a deep puff of cigarette, snuffed out the cigarette butt in the ashtray, and said: "Challenging the time of 500 feet for 2 minutes and 11 seconds is very easy for underwater divers to do at room temperature, and it is a test of life and death under the ice water close to 0 degrees. ”

Shang Minjie smiled and nodded: "It's easy to talk to smart people, after Steig went ashore, I re-tested his blood oxygen content, and I felt very incredible, the results of the before and after tests were surprisingly consistent, and there were no results as I expected, high before and after low, and the level of stress hormone adrenaline, the test results before and after were almost the same, and there was also no such thing as the predicted low and high test results." For those with medical knowledge, the blood oxygen content will become much lower than before after a large amount of oxygen is consumed, but Steig's physiological mechanism illustrates an unusual scientific example: the level of adrenaline will rise sharply because of the body's stress and fear, but Steig's value is a good reflection of his psychological mechanism beyond ordinary people. He then went on to complete the 1 minute 26 seconds 250 feet free diving without wetsuit under the ice, and a few days later, he challenged another underwater anaerobic diving project to challenge a huge marine iceberg, the goal of which is to dive under the iceberg at minus 2 degrees Celsius, dive into the area below the iceberg, and walk through the magical world of icebergs and water. ”

Yin Fatzi and Yin Yuting were both very excited when they heard it, and their expressions were full of reverence.

Wu Lang's face was as pale as a mirror, looking at Shang Minjie, just quietly listening to what she said.

"My team finally conducted a detailed and comprehensive physical test on Steig, Steig snorkeled in the water of minus 2 degrees Celsius without oxygen, the loss of body temperature seemed to be no problem for him, when he came ashore in the water, the body temperature we measured for him was 33.8 degrees, and when the body temperature of ordinary people dropped, there would be nervous system disorders, muscle spasms, the brain could not effectively control all parts of the body, cells were easily dehydrated and unconscious, and there would be cardiac arrest, but Steig would not he would remain intact. Steig's physiology and organ structure are extraordinary, the average lung capacity of a normal person is between 5 and 6 liters, and Steig's superhuman lungs are actually as large as an astonishing 14 liters, which is several times more than a normal person; his heart rate can be as low as 30, so the oxygen consumption will be surprisingly lower than that of normal people, and other metabolic functions of the body will also produce low levels, the main reason for these factors is his genetic variation, after testing, we found that Steig has seven pairs of genes with a different mutation structure than ordinary people, especially a group of gene combinations that can control energy conversion The mutation is the most obvious, as far as his superpowers are concernedWhether it's the ability to hold your breath underwater for a long time and the ability to challenge your physiological limits at ultra-low temperatures, all of this should be attributed to his genetic variation. Shang Minjie said.

Wu Lang smiled at her: "You said so much, the purpose is to give me a test to see what is different from ordinary people in my body, right." ”

Shang Minjie's face was slightly red, and she nodded a little embarrassed.

"Xiao Wen, you are the future daughter-in-law of the fat man, and I am the prospective brother-in-law of the fat man, we are in this relationship, I promised to let you do a test, but only this once, not as an example. Wu Lang looked at Shang Minjie coldly.

Yin Fat Man was stunned for a moment, looked at his wife, and then at Wu Lang, staring at the bull's eye, not knowing what to say.

Yin Yuting sat aside and gently pulled Wu Lang's arm.

"What do you want me to do, say it. Wu Lang smiled suddenly.

"I want you to do an underwater apnea test too, right in the bathroom tub. Shang Minjie said apologetically.

Wu Lang listened and nodded, did not speak, got up from the chair, took out the mobile phone and car keys in his pants pocket, handed them to Yin Yuting, walked into the bathroom, took off his T-shirt and outer pants, changed into a pair of beach shorts, and then lay down in the bathtub, quietly waiting for the water to fill up.

Shang Minjie, Yin Yuting, and Yin Fatzi stood beside them, looking at Wu Lang, who had been buried in the water from head to toe, and the time passed minute by minute, one minute, two minutes, three minutes......

Wu Lang in the water closed his eyes slightly, crossed his hands, and placed them quietly on his abdomen, his complexion did not fluctuate in the slightest, as if he was asleep......
