Chapter 172
Whether the human body can cross the void, the main problem is that space does not have the oxygen, pressure, and temperature required by the human body.

If a human being is exposed to space without any measures, the first injury he suffers is decompression.

Although the blood pressure of the human body can still maintain around 75 Torr when the external environmental pressure is zero, the boiling point of some substances also drops due to the drop in air pressure.

This causes small amounts of bodily fluids to evaporate and bubbles to form in the blood, which in turn leads to damage to the brain, nervous system, and eventually death.

The human body will not explode because of this, at most the lungs will be blown to pieces, because too much air is stored in the lungs, and they will rush out of the body crazily due to the large pressure difference.

In such a situation, if you forcefully hold your breath for oxygen, there will be an implosion, and the air will blow up the lung lobes and trachea, which will make people die faster.

So in a depressurized situation, the best thing to do is to exhale all the air immediately and live a little longer.

That is to say, when the human body is exposed to space, even if an oxygen tank is given to him, the lungs will not be able to work.

In this way, you will immediately face the second type of injury, hypoxia.

Not only are humans actively expelling gas, but under decompression, the body will passively evaporate and lose water, and the pores will also expel some gas, which makes the hypoxia more rapid.

Exhaling the air in the lungs in the atmosphere may hold it for tens of seconds longer, because body fluids and blood contain oxygen.But in space, just ten seconds can cause shock and even death.

As for the third type of injury, when humans can solve the problem of hypoxia, they need to face cold death.

This is actually the last danger to emerge.

Although the space environment is very cold, because there are few molecules in space and it is close to a vacuum, it is a good heat insulator. For people who are exposed for a short time, the heat will not leave the body immediately, only because of the moisture on the body surface. Part of the heat is taken away by evaporation, and slow heat radiation makes it feel cold, but it will not freeze to death immediately.

This kind of injury lasts for a long time, and people often die from lack of oxygen first, and then slowly freeze to death, and finally become a dehydrated mummy.

But in any case, a person can live up to ten seconds in space.

Being able to live for ten seconds means that you can live longer.

Bell said: "Master, with your body, you can survive in space for a short period of time. If you can solve the oxygen problem, you can even live for more than ten hours. That's because your body is too tough, and the skin locks water. With the rapid loss of gas, this makes you lose heat more slowly, and you're less oxygen deprived..."

Bai Ge said: "I have stored a lot of air in my brain hole, so I can directly breathe internally, and the oxygen problem is easy to solve."

Bell said: "But the pressure problem can't be solved. Although you can make your body constantly resist damage such as blood bubbles, body fluid evaporation, and nervous system damage, many organs in the body will no longer work when the external pressure is zero. This is the short board of human beings who were born in the atmosphere. Excessively high air pressure can rely on physical strength to support it, but it is difficult to adapt to too low air pressure."

"Ultra-speed regeneration can keep you fighting hard, but what about brain damage? Super-speed regeneration is constantly repairing, the brain is constantly damaged, and it is constantly repairing. To adapt to it, genes need to evolve themselves in such an environment for a long time. This time It could be long, would you like to be in space all day in a trance, confused, intermittent amnesia and uncoordinated body control?"

Bai Ge understands this, his body can indeed resist the space environment.

He wouldn't die even if the nuclear explosion was far away, so how could he die because of the space environment?

What really bothered him was normal thinking.This is a problem limited by human genes. In an ultra-low pressure environment, although he will not die, he will basically remain in a semi-brain-dead state for a long time.

He has super-speed regeneration, but thinking cannot always be intermittent.

"That is to say, it is enough for me to solve the problem of loss of pressure. After this problem is solved, I will no longer have to worry about pressure problems. I can adapt to low-pressure environments and resist hard-pressed environments. If I can't bear it, it's just my physical strength. It's just in place." Bai Ge said.

Bell said: "That's it, the pressure problem is solved, and the other problems are minor. Oxygen can use the brain hole to breathe, and the loss of water and heat will be extremely slow due to the strength of your body. Even cosmic rays will Ignored because of your heat-absorbing properties."

The universe is full of all kinds of rays, but no matter what kind of radiation, the essence is the propagation of heat.Radiation can destroy cells, but Baige's cells are the least afraid of heat.At best, it will be damaged by the impact of a large number of high-level subatomic particles contained in the rays. The body that can be trained by the Baige nuclear explosion is no different from the impact of a breeze.

Bell continued: "Of course, the extreme environment in some planets, such as the strong acid of Venus... may cause harm to you, but as long as the body is strong enough, it can be solved."

Bai Ge smiled, this is one of the reasons why he likes to be physically strong, his own strength is the root, and many small harms can be ignored.

"Understood, let's try it. You provide the plan, and I will operate it." Baige said.

Ling Dang immediately said: "The first plan is to increase the elasticity of your skin and bones through genetic modification, and remove [-]% of the pores. Only four to eight controllable pores in the whole body are enough..."

"Huh? Wait a minute! This plan won't work, try another one!"

After Bai Ge heard Ling Dang's plan, the image of Buu popped up in his head.

Bell said: "I will try my best to avoid affecting your human appearance. If it succeeds, you will still have a human appearance, at most..."

"No hair at most, right! Your plan is very problematic!" Bai Ge strongly refused.

Bell had no choice but to say: "Then are you willing to have an exoskeleton? In theory, it won't be like an insect, but a dozen special bones will be added to your head or tailbone, so that your body will automatically pressurize in a low-pressure environment." .”

"Uh...not good either!" Bai Ge thought for a while and refused again.

Next, Ling Dang proposed more than a dozen proposals. Although they did not change the basic characteristics of human beings, they always changed people more or less slightly.

After careful consideration, Bai Ge passed all of them.

In the end, Bell said: "I only have one last solution, and it will make your hair..."

"Why is it hair again! Well... since this is the last plan, I have to give up my hair for the sake of the stars and the sea..." Although Bai Ge cherishes his hair very much, he still has the courage to give it up at this moment.After all, even if he doesn't lose his hair now, as the pores get smaller, his hair will fall out sooner or later.

Bell said: "This time it's not about removing the hair, but changing the quality of the hair..."

"Oh? Just change the hair quality? That's okay." Bai Ge felt that he finally had a good solution.

Bell said: "Hair is the remains of dead cells in the human body. I can modify the gene so that the extension of your hair follicles are active cells, which are controlled by the brain nerves. It can not only pressurize your brain, but also control your hands and feet. to change its shape."

Bai Ge understood it, and said after thinking about it: "That is to say... I don't grow hair on my head, but flesh?"

"It's not all meat, there are also a small amount of bones and spongy bodies..." Bell said.

"Isn't that a tentacle?" Bai Ge frowned.

Bell said: "If you want to understand it this way, you can barely understand it, but in fact it should be... um... It's a living hair and hair! The extension of this organ will regulate the pressure in the body, and will not be affected by the low pressure outside. I will try my best to Make it black, so that on the surface, it will be the same as your hair, and you can even change your hairstyle anytime, anywhere, because it is an extension of your limbs... Be careful, if you trim it, it will bleed..."

Bai Ge clapped his hands and said: "Very good, that's it, basically there are only benefits! It not only solves the problem of loss of pressure, but also has an extra limb by the way!"

Bell said: "Actually, it can't be regarded as a limb. At best, it is a continuation of your intracranial muscles. In addition, it is not without disadvantages. If you are emotional, it is likely to be congested, and it will have a neural self-reaction similar to 'knee jump'... ..."

Bai Ge said with a smile: "This is a small problem. It is better to be fake than to have no hair. Let's work hard according to this plan!"

The bell said: "Okay, the stele will back up your genes at this moment. I will continue to try to modify them. If you make mistakes, your genes will collapse, but you will not die. If you are correct, but you may not succeed in achieving this effect, it may make you It becomes something else. But no matter what, I will record it in detail and reset your genes until the law is summed up and this effect is achieved."

Bai Ge said with a smile: "That is to say, if you are lucky, maybe the east end is not bright, but the west end is bright. What other powerful genes are unintentionally created?"

Bell said: "There is such a possibility. In short, all rational genes, as long as they are tested on you, the stone tablet will record them. The more we do, the more materials we can study, the more materials, the more ideas and directions. If there are more, the more correct the conclusions will be, and then there will be more research materials..."

"Through this repetition, the more we know, the more we may not know. Gene research is a long way, and we are just beginning now."
