The main problem was that there was no oxygen, pressure, and temperature in space that the human body needed.
If a human was exposed to space without any protection, the first injury he would suffer would be a loss of pressure.
Although a human's blood pressure could still be maintained at about 75 Torr when the external environmental pressure was zero, the boiling point of some substances would also decrease due to the drop in pressure.
This would cause a small amount of body fluid to evaporate and bubbles to appear in the blood. This would then cause damage to the brain and nervous system until death.
The human body would not explode because of this. At most, the lungs would be blown up because there was too much air stored in the lungs. The air would rush out of the body due to the large difference in pressure.
In such a situation, if one forcibly held their breath for oxygen, there would be an implosion. The air would blow up the lungs and trachea, causing the person to die even faster.
Therefore, in the case of a loss of pressure, the best way was to immediately exhale all the air. This would allow one to live for a little longer.
In other words, if a human was exposed to space, even if they were given an oxygen tank, their lungs would not be able to work.
In this way, they would immediately face the second type of injury — lack of oxygen.
Humans were not the only ones who actively exhaled air. In the case of a loss of pressure, the body would passively lose water through evaporation. Part of the air would also be expelled from the pores, causing the lack of oxygen to worsen.
In the atmosphere, the lungs might be able to hold the air for a few more seconds because the body fluid and blood contained oxygen. However, in space, a mere ten seconds would cause a person to go into shock or even die.
As for the third type of injury, it was when a human could solve the problem of lack of oxygen. Cold death.
This was actually a danger that would only appear at the very end.
Although the environment in space was very cold, there were very few molecules in space and it was close to a vacuum. Therefore, it was a good heat insulator. For a person who was exposed for a short period of time, the heat would not immediately leave the body. It would only be due to the evaporation of water on the surface of the body that would take away some of the heat and slow heat radiation that would cause the person to feel cold. However, the person would not immediately freeze to death.
This type of injury would last for a long time. Usually, the person would first die from lack of oxygen, then slowly freeze to become a dehydrated corpse.
However, no matter what, a person could live for at most ten seconds in space.
Being able to live for ten seconds meant that they could live longer.
Ling Dang said, "Ruler, with your body, you can survive in space for a short period of time. If you can solve the problem of oxygen, you can even live for more than ten hours. That's because your body is too tough, and your skin locks in the rapid loss of water and gas. This will slow down the loss of heat and oxygen … "
Bai Ge said, "I have stored a large amount of air in my brain, so I can breathe directly. The oxygen problem can be solved easily."
Ling Dang said, "But there's no way to solve the problem of pressure. Although you can make your body resist blood bubbles, body fluid evaporation, and damage to your nervous system, many of your organs won't work when the external pressure is zero. This is the shortcoming of humans born in the atmosphere. They can still rely on their physical strength to withstand high atmospheric pressure, but it is very difficult to adapt to low atmospheric pressure. "
"Super Regeneration can allow you to continue enduring, but what about brain damage? His brain was constantly damaged and repaired by Overdrive Regeneration. His brain was constantly damaged and repaired. To adapt to it, the genes needed to evolve in such an environment over a long period of time. This may take a very long time. Are you willing to be in a trance in space all day long, with your consciousness blurry, intermittent amnesia, and body uncoordinated? "
Bai Ge understood this. His body could indeed withstand the harsh environment of space.
He wouldn't die even if he was far away from a nuclear explosion, so how could he die from the harsh environment of space?
What really troubled him was his ability to think normally. This was a problem limited by human genes. In an ultra-low-pressure environment, although he wouldn't die, he would basically be in a semi-retarded state for a long time.
He had Overdrive Regeneration, but his thinking couldn't always be intermittent.
"In other words, I only need to solve the problem of pressure loss. If this problem is solved, I won't have to worry about pressure in the future. I can adapt to low-pressure environments, but I can resist high-pressure environments. If I can't withstand it, it's just that my body isn't strong enough," Bai Ge said.
Ling Dang said, "That's it. After solving the problem of pressure, everything else is a small problem. Oxygen can be breathed in through the brain hole, and the loss of water and heat will be extremely slow because of your physical strength. Even cosmic rays will be ignored because of your heat-absorbing characteristics. "
The universe was full of all kinds of rays, but no matter what kind of radiation it was, its essence was the transmission of heat. Radiation would destroy cells, but Bai Ge's cells were the least afraid of heat. At best, they would be damaged by the impact of a large number of high-subatomic particles contained in the rays, but with Bai Ge's body tempered by nuclear explosions, this impact was no different from a gentle breeze.
Ling Dang continued, "Of course, the extreme environments on some planets, such as Venus' strong acid … may cause you harm, but as long as your body is strong enough, it can be solved."
Bai Ge smiled. This was one of the reasons why he liked to have a strong body. Personal strength was fundamental, and many small dangers could be ignored.
"Got it, then let's give it a try. You provide the plan, and I'll do it, "Bai Ge said.
Ling Dang immediately said, "The first plan is to use genetic modification to increase the elasticity of your skin and bones, and remove 99% of your pores. You only need to have four to eight controllable pores on your body …"
"Hmm? Wait a minute! This plan won't work, change it! "
Bai Ge listened to Ling Dang's plan, and the image of Buu suddenly popped up in his mind.
Ling Dang said, "I will try my best to avoid affecting your human appearance. If it succeeds, you will still have a human appearance, at most …"
"At most, you will have no hair! Your plan is very problematic! "Bai Ge strongly rejected.
Ling Dang had no choice but to say, "Then are you willing to have an exoskeleton? In theory, it won't be like an insect. It will just add a dozen special bones on your head or tailbone, and your body will automatically pressurize in a low-pressure environment. "
"Uh … that's not good either!" Bai Ge thought about it and rejected again.
Next, Ling Dang proposed more than a dozen plans. Although they did not change the basic characteristics of humans, they would more or less make people change slightly.
Bai Ge thought about it carefully and passed on all of them.
Finally, Ling Dang said, "I only have one last plan, it will make your hair …"
"Why is it hair again! Okay … Since it's the last plan, for the sake of the sea of stars, I have to give up on my hair … "Although Bai Ge cherished his hair very much, he still had the courage to give it up at this moment. After all, even if he did not lose his hair now, as his pores became smaller and smaller, his hair would fall out sooner or later.
Ling Dang said, "This time, it's not about removing your hair, but changing your hair texture …"
"Oh? Just changing the hair texture? That's not bad. "Bai Ge felt that he finally had a good plan.
Ling Dang said, "Hair is the remains of dead cells in the human body. I can modify your genes and make the hair follicles extend with living cells, which are controlled by the cranial nerves. Not only can it pressurize your brain, but it can also change its shape like controlling your hands and feet. "
Bai Ge understood and said in his mind, "In other words … what grows on my head is not hair, but meat?"
"It's not all meat, there are also some bones and spongy bodies …" Ling Dang said.
"Isn't that a tentacle?" Bai Ge raised his eyebrows.
Ling Dang said, "If you want to understand it that way, it's barely okay, but actually it should be … Hmm … It's a fleshy tentacle with living hair! The extension of this organ will regulate the pressure in the body and will not be affected by the external pressure. I will try my best to make it black, so that on the surface, it will look like hair. It can even be changed according to your wishes, because it's an extension of your limbs … Take note, if you trim it, it will bleed … "
Bai Ge clapped and said, "Very good, that's it. Basically, there are only benefits! Not only does it solve the problem of pressure loss, but it also gives you another kind of limb! "
Ling Dang said, "Actually, it can't be considered a limb. At best, it's an extension of your cranial muscles. Also, it's not without disadvantages. If you get emotional, it's very likely that blood will rush, and there will be a nerve reaction similar to 'knee jerk' … "
Bai Ge smiled and said, "These are all small problems. It can be passed off as real, so it's better than having no hair at all. Just work hard according to this plan!"
Ling Dang said, "Okay, the stone tablet will back up your current genes. I will constantly try to modify it. If it's wrong, your genes will collapse, but you won't die. If it's right, but it may not succeed in achieving this effect, it's very likely that it will turn you into something else. But no matter what, I will record it in detail and reset your genes until I summarize the pattern and achieve this effect. "
Bai Ge smiled and said, "In other words, if we're lucky, maybe the east will not be bright, but the west will be bright. What kind of powerful genes will we inadvertently create? "
Ling Dang said, "There's such a possibility. In short, as long as it's tested on your body, the stone tablet will record it. The more we do, the more material we can study. The more material we have, the more ideas and directions we can follow, and the more accurate the pattern we summarize will be. Then, there will be more material for us to study … "
"In this way, the more we know, the more unknowns there may be. The research of genes is a long road, and we've just begun. "
