Ten o'clock in the evening.

Zhao Heng and Xu Manni sent their parents home separately, and the two also went home, as for Xu Hongdou, they went home, saying that they had to sleep there during this time, just because they were preparing to open a store.

Back home, sitting on the sofa, Xu Manni couldn't help but breathe a sigh of relief, she was still very satisfied with the meeting of the parents today, in general, everything was fine.

"Before my mother left, she said that this time it would be an engagement, saying that we were both busy, and we would wait until we got married later."

Xu Manni sat on the sofa, took a sip of water, and said to Zhao Heng, who was sitting next to her.

"That'll do."

Zhao Heng nodded, he liked such a simple mother-in-law.

Originally, with his character, the marriage ceremony or something, he didn't think it was necessary, but for Xu Manni, a woman, this is still indispensable.

"Is skin anti-aging really as simple as you say?"

Xu Manni leaned on the top and asked Zhao Heng casually.

Women, what they are most interested in is nothing more than taking care of themselves, especially when Xu Manni has reached the age of thirty, when she is not young, and she is not old when she is young.

Whether you look old or not is actually related to genes, and so is your skin.

There has always been a joke that "men are forty-one flowers, women are forty tofu scum", middle-aged women often encounter such confusion in life, obviously they spend more time and energy than men to maintain their skin, but they still can't stop aging faster than men.

The main reason for this is the loss of collagen.

Collagen is an essential nutrient for the human body to delay aging, one of the main components of the skin, and the most abundant protein in the human body, accounting for more than 30% of the total protein in the human body; It is distributed in various tissues and organs of the body, such as human skin, bones, muscles, cartilage, joints, hair tissues, etc., and plays a triple anti-aging role of support, repair and protection.

At the same age, women lose collagen at a higher rate than men. This is mainly determined by the physiological characteristics of women, such as the endometrium shedding during women's menstruation, and the damaged endometrium needs to be repaired, and the endometrium is composed of collagen, which requires the consumption of a large amount of collagen; There is also a certain amount of damage to the uterus of women, and a large amount of collagen will also be consumed at this time.

After the age of 20, the collagen in the body begins to be lost, and the woman begins to gradually age; Loss peaks after the age of 25, and the collagen content at the age of 40 is only half of what it was at the age of 18. With the loss of collagen, the most direct manifestation of women is that the skin becomes dry, saggy, wrinkled, pigmented, enlarged pores, and begins to become sagging.

"It's not difficult, as long as you regulate the collagen expression related genes, you can make the skin state always 18 years old or even younger."

Zhao Heng thought for a while and said.

For his current level and technology, even those congenital genetic diseases are not a problem, let alone a little antioxidant and anti-aging technology.

"Gene regulation? Didn't I hear that this technique is still in the theoretical stage?"

Xu Manni asked with some doubts, it was not that she didn't believe Zhao Heng's words, but the directional expression and regulation of genes were still in the theoretical stage all over the world, for example, human beings had just completed the sequencing of the human genome.

"It's naturally impossible to regulate the whole thing, but it's still possible to adjust individual genes."

Zhao Heng said.

"Really? You say that this gene regulation is not like in a science fiction movie, and the side effect is that it will turn people into monsters or something, right?"

Xu Manni said in disbelief, although she is also a medical professional, but her understanding of the high-level and cutting-edge discipline of gene regulation is, to a certain extent, no different from ordinary people.

"Where do you want to go, just talk about skin anti-aging, as long as the related genes that originally decreased with age are reactivated, so that the expression of collagen can be regulated to ten, for example

Eight years old or even higher, it's fine, it's just a process of reactivation, there is no genetic modification, shearing and modification, basically there is no risk."

Zhao Heng smiled and said.

"I see what you mean, reactivating gene expression is like re-unscrewing a valve."

Hearing Zhao Heng say this, Xu Manni immediately understood.

The thought that her skin can remain the state of a young girl forever, Xu Manni, as a woman, is completely unable to resist this attraction.

"This kind of technology, once it is put into practice, is very exaggerated when you think about it."

After a pause, Xu Manni said again.

Now skin anti-aging products are already sold at sky-high prices, and a small bottle of tens of milliliters of cosmetics, as long as it contains a little anti-aging ingredient, can be sold for thousands of yuan.

Even a face mask can be sold for hundreds or even thousands of dollars.

The profit contained in this is simply a big exaggeration.

Not to mention, the way of gene regulation that Zhao Heng said is to continuously and even permanently change the expression of collagen, which would not be crazy if those rich and beauty-loving women knew about it.

"This technology is difficult to popularize on a large scale, and to do genetic fine-tuning, it is necessary to first draw a genetic map for the individual, and then use nanorobots to make targeted adjustments, which is much more expensive than the surgery or treatment items in those beauty hospitals."

Zhao Heng shook his head slightly and said.

If it can really be rolled out on a large scale, tens of billions of dollars of revenue will come in minutes.

But in fact, it's not that simple.

Gene regulation is destined to be a personalized and personalized customized treatment, which cannot be rolled out on a large scale, as if it can be condensed in a bottle of medicine.

You know, everyone's genetic sequence, that is very different.

"Then you give me a try on this technique first, although I'm in good shape now, but in a few years, I'm afraid my skin will go downhill."

Xu Manni leaned on Zhao Heng and said with a smile.

"Okay."

Zhao Heng nodded very dryly.

"Are there really no side effects?"

Xu Manni asked uneasily.

"You've watched a lot of science fiction movies.

It's about reactivating a gene, allowing it to be expressed again, without any modifications, modifications, or shearing changes, which is the most basic and initial in terms of genetic modification."

Zhao Heng explained.

"Again, it's not about making people grow wings, or being bitten by a spider and becoming Spider-Man like in the movies, or giving people the vision of an eagle or something."

As soon as Zhao Heng said this, Xu Manni thought about it for a while, and it seemed that this was indeed the case.

But it's just because I hear the word genes, it's too high-minded, and it feels like some kind of amazing science and technology.

"How it is possible for human genes to be mixed with those of animals or even insects, and the idea of strengthening the human body with the strengths of animals is completely a science fantasy."

Zhao Heng said with a smile.

Man's strength is intelligence, whether it is speed, strength, eyesight, or the strength of other living beings, and human beings can use their intelligence to study the effect of replacing it with something.

In terms of human body transformation, the most important thing for human beings to do is to live longer and healthier, nothing more.

The idea that people have the power of a bear, the eyesight of an eagle, the reaction speed of a cat, etc., is just a kind of science fantasy, and in reality, it is not as good as developing external armor or exoskeletons.

Of course, science fantasy, since it's fantasy, it's a kind of romanticism, just like a humanoid bipedal mecha, which is completely redundant in terms of practical application, and it turns out that where it's a vehicle, the track is king.

"Actually, if it's really this technology

If you are mature, I think it is okay to set up a medical aesthetic center, and you should earn the money instead of letting those scammers make it."

Xu Manni thought about it and said that with the development of the medical beauty industry, many tertiary hospitals have set up relevant departments.

"It's very difficult, genetics is a very difficult subject, and mapping a person's genome is not something that ordinary doctors or even researchers can do."

Zhao Heng shook his head slightly.

"It's a matter of people, when any technology just appeared, there were very few people who mastered it."

Xu Manni said disappreciatively.

Although she and Zhao Heng can now be said to have basically achieved financial freedom, no one will be disgusted with more money.

She and Zhao Heng, neither of them are the kind of people who care about material things very much, but in this world, if you don't have money, you can't do many things.

"And how long will it take for you to make this adjustment for me?"

After a pause, Xu Manni asked very curiously.

"About two months."

Zhao Heng thought for a moment and gave a time.

"Two months for one person?"

Only then did Xu Manni know why Zhao Heng said that this method can only be individualized treatment at present.

It takes two months for one person, which is far from the standard of practical application, let alone commercial use.

"Two months is a short time."

Zhao Heng shook his head slightly and said.

"It's also a good deal to be able to change your youth forever in two months."

Xu Manni said thoughtfully.

With the development of science and technology, eternal youth, at least on the outside, is actually not an unattainable goal.

Although the path is different, there are many types of technology that can achieve this effect.

The fine-tuning of gene expression mastered by Zhao Heng can be said to be the most direct means.

It's only been two months, and if you count it, it's not long at all, look at those female stars, in order to maintain their skin and figure, it's too hard.

"What about weight loss? Can it also be regulated? Is it possible to achieve the effect of not being able to eat fat?"

Xu Manni asked again.

"It can be done, but it doesn't have to."

Zhao Heng thought for a while and said.

"Why is it not necessary? Now many people, especially girls, are struggling to lose weight."

Xu Manni said with some puzzlement.

"If everyone is thin, there is no point in being thin."

Zhao Heng said slowly.

A lot of things, the ideal state is one thing, but it's actually another.

For example, if the average life expectancy of human beings is extended to 100 years when the productive forces are not developed enough, this may seem like a good thing at first glance, but it is not necessarily true.

Just as why the fertility rate is falling below 0.5 now, what is the concept of the fertility rate falling below 0.5?

In other words, only one of the two women of childbearing age is not willing to have children.

So we have to ask, why is everyone reluctant to have children?

There may be many reasons, and experts can also analyze ten or twenty factors, but presumably the strongest and truest thought in the hearts of young people will be: I don't want my children to suffer again, why bother!

"What you mean by this is the same as if there were only rich people in the world, then there would be no rich people, this is a truth."

[In view of the general environment,

Xu Manni said thoughtfully.

Xu Manni is an extremely smart woman, in Zhao Heng's opinion, except for Song Chen, who has gone away to the other side of the ocean, Zhao Heng has never seen a smarter woman than her.

"Almost."

Zhao Heng nodded.

"You're tired today, so go to bed early

。」

After a pause, Zhao Heng said to Xu Manni again.

He knew that Xu Manni was already very tired when he went to work during the day today, and he had to arrange a meeting for dinner after work, and he must be very tired now.

"But we haven't had it for a long time.

」

Xu Manni said again and again.

She knew that at Zhao Heng's age, there were some things that could not be missing every day, and the work of the two of them was already very busy, so they could basically only reach two or three times a week.

It's just that Zhao Heng is the type with good physical endurance, if it weren't for the fact that she knew that Zhao Heng was also very busy with work and basically didn't have time to do anything else, she would have to start worrying now.

"You can rest well."

Zhao Heng smiled slightly and looked at Xu Manni and said.

To be honest, in the beginning, maybe he will be a little enthusiastic, but everything is the same, and after a lot of more, that's what it is.

Moreover, for the current Zhao Heng, how to realize his ideals and change the world to the greatest extent is what can really make people's blood boil!

Just think about it, prolong life, eliminate cancer, or many things that I didn't dare to think about before, after the system has the function of [breaking the limit], Zhao Heng dares to say that as long as he is given time, maybe he can change the whole world, not necessarily.

"Why not a little? To be honest, I've been a little stressed lately."

Xu Manni said again.

Studies have shown that it is arguably the most effective human behavior in terms of stress relief.

"Huh?"

Zhao Heng was a little confused by these words.

Stressed?

And then you want to.

？

But when he thought about it, it seemed normal, this thing can indeed relieve stress a lot, because in this process, the human body will secrete a huge amount of dopamine, which makes people feel relaxed and comfortable.

Zhao Heng, who originally wanted a truce, seemed to have to face another night of world war.
