"It definitely has benefits. Nitrogen will of course dissolve into the blood, but it does not participate in biochemical reactions. The more it enters, the less it enters, it depends on the pressure. For example, when you dive deeply, the nitrogen content in your blood will be high, and it will quickly

The floating nitrogen precipitates out of the liquid and blocks the blood vessels. This is diving disease. This guy can solve the nitrogen problem."

Quietly and still lazy.

"All right!"

Lin Shuang had also heard of the diving disease. He didn't think about it carefully at the time. He just thought that people were very fragile. Now he realizes that this is still not evolved enough.

It has evolved now.

But at what cost?

Don't forget, he must not be aesthetically different from Tang Yuan and others.

For example, in order to become stronger, you would grow scales on your skin and wear a composite armor. This is absolutely not allowed!

But there is a wingsuit growth under the skin and on the bones. Unless you have clairvoyant eyes like Liffy, how can others detect it?

To put it bluntly, humans are visual animals.

Lin Shuang checks himself every day. Apart from being healthy and white, his skin has no color changes, which means that Xiao Wai has no problem controlling his body modification. At this point, he can only go on.

Being able to hold your breath for two hours greatly increases your chances of surviving when faced with danger. This is actually a good thing, and people should not be too pretentious.

Mission accepted.

Holding his breath for two hours was not enough. Lin Shuang took a deep breath, picked up his phone, and started to browse data in the water. His phone was also waterproof. Recently, he felt that not only was he uneducated, but he also lacked knowledge.

Watching him soaking in the pool under the sun, Qian Er silently moved a big parasol for him.

Cheng Miao and Cheng Quan are here.

Lin Shuang didn't even raise his head: "Is the translation ready?"

Because I was holding my breath, I used all my remaining breath, and my tone was a little harsh.

Cheng Miao said weakly: "Come here and take a look at you, and I'll go back right away."

Cheng Quan was not so sensitive and squatted down: "Lin Shuang, it turns out that we have had penicillin as medicine for a long time. It was made from fermented mustard greens. It was also found in mustard stew in the Ming Dynasty and in herbal supplements. When we were applying the medicine just now, Sun Yan told us

Oh...ah, she knows so much!"

"There is a saying in the TV series Old Chinese Medicine: If we add this to a variety show, will there be any infringement issues?"

"no...."

What Lin Shuang originally wanted to say was suppressed by himself.

He originally wanted to tell Cheng Miao and Cheng Miao that after reading Materia Medica and then reading Baopuzi, you can probably write a fairy novel, but suddenly he felt that there was no point in saying this.

The variety show in front of me hasn't even started yet.

Cheng Miao and Cheng Miao stood for a while and then left. In fact, they had a lot to do. The key was that they were not particularly smart and could only rely on interest and normal hard work.

After a while, Tang Gulifei came over and sat under the umbrella, painting quietly.

The little girl is actually quite sensible, and she must have been taught well by Lin Zhao.

Lin Shuang looked at his mobile phone, and some of the information he found on his mobile phone slowly merged with the knowledge he had learned before. He started learning biology in junior high school, and he actually already knew some superficial knowledge in elementary school or even kindergarten.

The photosynthesis of plants is reversible. There is something in the human body called ATP, which is a chemical molecule. You can simply understand it as "flash storage" of energy. ATP can give up part of itself at any time to form ADP, which is energy.

is used and the flash memory is cleared.

Glucose is a mechanical hard drive that stores a large amount of energy. When it enters the body, it actually transfers its energy to ADP to form ATP.

A system of complex biochemical reactions makes the human body full of vitality, which is brought about by long-term evolution.

On the other hand, the early Earth did not have that much oxygen and was full of anaerobic organisms, such as cyanobacteria.

It has been 4.6 billion years since the earth was born, and free oxygen did not appear on the earth until about 2.4 billion years ago. About one billion years before that, cyanobacteria (cyanobacteria) appeared and began to perform photosynthesis. The oxygen produced in this process was a by-product.

product.

This oxygen does not float into the atmosphere, but reacts with silicon to form silicates, or with iron to form iron oxide or rust. After a billion years of consumption, the system is eventually saturated, with excess oxygen, and begins to flow freely.

Accumulated in the atmosphere. However, oxygen was toxic to anaerobic organisms living on the earth at that time, and it led to the first mass extinction-the atmospheric oxidation event.

Under the tremendous pressure brought by rising oxygen levels, life has evolved different survival strategies. Among them, eukaryotes evolved multi-cellular life and changed the metabolic pathways of chemical synthesis to use oxygen.

In other words, the life system has been updated, just like a computer has changed its operating system.

It's hard to say which one is more advanced. Anyway, most people can't live without oxygen.

"Cough..." Tang Gulifei coughed slightly.

Lin Shuang looked over and said nothing. He just cast a concerned and questioning look: Have you been vaccinated?

Tang Gulifei didn't say anything, but the movements of her hands sped up, in order to draw Lin Shuang's front view.

Lin Shuang smiled and looked back at the phone.

Let her look at it.

Chemistry common sense, although nitrogen and oxygen in the air are relatively stable, there are many ways to combine these two substances, from nitric oxide to nitrogen dioxide, to dinitrogen trioxide, dinitrogen tetroxide, and dinitrogen pentoxide

...

As long as the conditions are right, there are many ways to combine them.

Although some substances are toxic on the surface, in reality, it is another situation in the human body. For example, nitric oxide is actually a very important messenger molecule that can dilate blood vessels in the human body.

Nitroglycerin can treat heart disease. In fact, the most important mechanism is that it degrades into nitric oxide in the body.

What does it feel like not to breathe the entire time?

The answer was that he didn't feel anything. Lin Shuang didn't even realize whether he was breathing.

Xiao Wai modified his lungs so that nitrogen can easily enter the blood through the alveolar respiratory membrane, which may be where nitrogen and oxygen are combined.

Part of the bound nitric oxide dilates the blood vessels, making them wider and able to deliver more blood to the body. Then there may be nitrous oxide.

This kind of stuff called laughing gas can make people feel happy and unable to stop laughing. It is stable at room temperature and has anesthetic and analgesic effects.

Lin Shuang sometimes wonders how his body can be healed after such a big change, and he can even get a good night's sleep. Now he guesses that this thing may have worked, if Xiaowai hadn't blocked all the nerve signals.

If so.

In addition, laughing gas is an oxidant and is also used as a fuel additive for rockets and racing cars. It is also an important greenhouse gas and can destroy ozone.

Excessive oxygen content is also harmful to the human body. Life lies in energy and also in reducing energy consumption.

Maybe the reaction in the body is much more complicated than I guessed.

I am really looking forward to how far I can grow...

The magic of life science is that it is a kind of coexistence of risks and benefits. The way forward can only be imagined, and the evolutionary history of the process has not yet been clarified for billions of years.

Who created this system?

Or two?

Lin Shuang didn't dare to ask more questions. He should leave this kind of thing to time. Even if the gift of fate has a price tag, he can accept it happily. Will he still be worse than himself before?

"Brother studies very seriously!" Tang Gulifei muttered, "Is it studying?"

Lin Shuang raised his head and smiled and nodded. During the mission, it was not convenient for him to speak.

Thinking about it this way, he should learn how to vocalize without using airflow, so that he can let his skin move around without rubbing or making ventriloquism or anything like that.

Except for Life, no one else deliberately came close.
