The equipment was delivered to the base, and the technicians came with it, but whether or not to use this technology caused a heated discussion in the expedition team.

"I think we have to be cautious!" Zhan Wenyi has a clear position, "The prospect of this technology is very good, but the experimental data is too small, and it is used in such an important task, in case something goes wrong, we can't afford to take this responsibility!" ”

Li Hui pushed his glasses: "This chief, our experimental data is very sufficient, I myself have had more than seventy low-temperature sleeps, the shortest is six hours, the longest is seventy-four hours, my body is very healthy now, there are no problems." ”

"Okay, then let me ask you, how long did it take you to sleep more than seventy times?" Zhan Wenyi asked loudly.

Lihui's confidence was immediately half discharged: "Intermittently, more than a year." ”

"Listen, listen to everything, I only sleep more than 70 times a year, and only once every five days on average, right? When our astronauts go to the sky, they have to sleep every day? Zhan Wenyi was even more imposing, "I won't talk about anything else, you just say that in case of an accident, can you ensure the safety of astronauts?" ”

Lihui wanted to say yes, but he really didn't dare to say anything about such a guarantee. 、

He could only explain with a wry smile: "This chief, I'm just a technician, and the decision is not made by me, and it is not up to me to decide whether to use it or not." ”

Zhan Wenyi immediately aimed the muzzle at Shan Qiuyu: "Old Dan, do you agree with this plan?" ”

Shan Qiuyu pondered for a moment: "If you can achieve the ideal effect under the premise of ensuring safety, I agree." ”

The benefits of a long period of sleep are definitely not only superficial, but more importantly, after the metabolism is reduced, the body's consumption will also be reduced, and the oxygen, water and supplies will all be reduced.

Above the sky, water can be solved by circulation, air can be solved by electrolysis of water and air circulation, and even food can be partially solved by carbon dioxide synthesizing starch.

However, a year-long voyage still requires a lot of supplies, and water and food alone are a huge burden.

Sleeping at low temperatures can save a lot of food, thereby saving the corresponding space, bringing more weapons and equipment, and greatly enhancing endurance and combat capability.

From this point of view, this technology is very significant.

However, although the volume of the cryogenic sleep chamber is similar to that of a traditional sleeping cabin, the latter is just a pressurized sleeping bag, plus a small piece of space, and there is very little additional equipment. The former requires a series of equipment to assist, and in this regard, it not only takes up valuable space on the ship, but also makes the structure of the battleship more complex, and indirectly increases the number of launches of the carrier spacecraft.

All things considered, the advantages outweigh the disadvantages, and Zhan Wenyi finally took a step back: "Until a clear result is reached, I reserve my opinion!" ”

And so, a special experiment began.

The technicians sent a low-temperature sleeping pod into the dormitory building, and Lihui was ready, lying down in the sleeping pod under the watchful eyes of all the trainees, and after half an hour, he successfully entered a critical sleep state of 15 degrees.

This sleep was more than seventy hours, during which everyone could observe his state at all times, and the temperature of the sleep pod could also be detected by non-destructive means.

In a word, I will sleep with you to dispel your worries and boost your confidence through practical actions.

Ou Zhanpeng deliberately glanced over, and under the transparent hatch, there was Lihui's sleeping appearance.

Touching it with your hands, the hatch cover is slightly cool, but that's about it.

Three days later, the sleep pod was opened in front of all the training team members, and Hui was unharmed, for which he also conducted a five-minute live questioning to prove that his brain was not affected in any way.

This time, even Zhan Wenyi, who was the most worried, had nothing to say.

From this day on, the training of the expedition team was divided into two parts, simulation during the day, theory at night, and finally cryogenic sleep.

Twenty-four hours a day, except for eating, drinking, and lazing, all the rest of the time is spent on training, and not a second is allowed to be wasted.

Even so, everyone still has a sense of urgency that time is not waiting, and they can't wait to break a second into eight petals.

However, when I really came into contact with low-temperature sleep, I found that this technology is not as simple as I imagined, and not just anyone can adapt to this sleep style immediately.

The first time he entered the cryogenic sleep pod, it took Ling Xiao a full three hours to successfully lower his body temperature to 17 degrees.

Shan Qiuyu's expression was very solemn, and he suddenly felt that low temperature sleep was a pit.

Li Hui observed his words, leaned over quietly, and explained softly: "This is all normal, and there must be a process of habitation." ”

Shan Qiuyu raised his eyebrows slightly: "Are you sure?" ”

The departure time is getting closer and closer, and if you can't finish the training before the window comes, you have to abandon the technology.

"According to our experimental data, the average adaptation time is five to seven days, and some people are slightly longer, that is, about ten days." Lihui's tone was full of confidence.

Shan Qiuyu nodded: "Okay, within ten days, I want to see the effect." ”

"No problem!" Lihui said

However, this was just the beginning, and after a while, new news came: Xu Qing entered the sleeping pod for seven hours, but her body temperature was always maintained at 28 degrees. No matter how much the dosage is increased, or they are urged to anesthetize, all the ways they have thought of have been tried, but there is still no improvement, as if she was called by God to make trouble, which made the entire technical team startled, and did not dare to continue to lower the temperature.

It was the first time that Lihui had encountered such a situation, and he didn't know what to do at all, let alone intervene at will, so he could only observe it for a while.

The problem here has not been solved, and there is trouble over there, Lotu fell asleep quite smoothly, and his body temperature dropped to 17 degrees, but the activity of the brain has not decreased, and he only slept for seven hours, and he woke up naturally without performing the warming program.

Lihui has one head and two big, what kind of strange group is this, why is there no one normal? Could it be because the previous experimental subjects were all ordinary people, and these were astronauts whose physique far exceeded that of ordinary people?

He put forward this idea, and Shan Qiuyu and Zhan Wenyi's opinions are highly consistent: the quality of the astronaut's physique is not directly related to the success of low temperature sleep, and the problem cannot be solved, either there is a problem with the technology itself, or the level of the technical team is too poor.

In short, the safety of astronauts must be guaranteed; Second, the ten-day period is non-negotiable.

Lihui almost didn't cry, but he always firmly believed that there must be a few, and he didn't dare to expect that everyone would not have accidents, but he must control the proportion below the safety line!
