Four days later.

In Cui Haixing's research institute, Chen Mengchuan and a group of staff members were discussing the experimental plan.

"Minister Chen, we have a high degree of certainty that these two projects can be completed, and we will definitely live up to the expectations of human civilization." The middle-aged man Ding Xiancheng looked a little excited.

Chen Mengchuan patted him on the arm: "Lao Ding, you think too much, you can do your best, you don't have to talk about it so macroscopicly." ”

Ding Xiancheng's expression was still a little excited.

"You have to adjust your emotions, and Xing Lao will come over in a while. This will be a real clinical trial of human civilization in DNA gene editing technology, and you look so excited, I'm afraid you won't be able to hold the scalpel well. Chen Mengchuan said with a smile.

Ding Xiancheng nodded and answered the voice.

Not long after, a group of people appeared in the researcher and walked towards Chen Mengchuan and the others, led by an old man in a wheelchair.

Seeing someone appear, Chen Mengchuan walked over with a smile: "Old Xing, you are here." How was your rest yesterday? ”

The old man in the wheelchair smiled: "What else can I do, just like that, I'm old, I'm shallow, and I can't sleep long." ”

"Xing Lao, this is the person in charge of the entire project this time, Ding Xiancheng. Lao Ding, this is Xing Lao. Chen Mengchuan introduced each other.

"Hahaha, I'll shout at you Xiao Ding, Xiao Ding, I'll hand over my old bones to you today." Xing Lao said with a smile.

Ding Xiancheng's mood was obviously much calmer, and he shook hands with Xing Lao and replied to him as calmly as possible: "Don't worry, you should sleep, I'll call you when it's over." ”

"Haha, you are still polite, with honorifics, look at Xiao Chen, this little guy, he is not as polite as you." Xing Lao made a joke.

Chen Mengchuan smiled beside him.

A group of people stopped talking and slowly entered the experimental area.

Chen Mengchuan followed him all the way to the end, and watched Xing Lao enter the final sterile laboratory.

Today's surgery will be done in this sterile laboratory and is expected to take 4 and a half hours.

Ding Xiancheng is one of the senior biologists in the entire Cui Hai Starfish, and he is also proficient in medical treatment and surgery.

After a period of experimental testing, the life extension program will be officially implemented on the human body today. Xing Lao was the first test subject, and he was also the best volunteer.

There are many reasons for choosing Xing Lao, and there is no shortage of volunteers, but after comprehensive consideration, Chen Mengchuan and others confirmed Xing Lao.

92-year-old Xing Lao, almost to the last moment of his life, he has contributed to the development of science and technology in China, and to the cause of education in China.

I stayed in the education position until I was in my 80s, and then I really retired.

Today's Xing Lao, although he is over 90 years old, is still in good spirits and has a very good mentality, and he has also expressed a strong willingness to cooperate with the life extension plan.

After the door to the lab was closed, everyone left the current area and went to the lab area.

Several gravitational screens allow everyone to clearly see the entire surgical experiment.

The time elapsed by an organism from birth to death is generally measured in years, and its lifetime is its lifespan.

Human beings' pursuit of life span has been from ancient times to the present.

There are many factors that affect the lifespan of an individual human being. More important ones include gender, genetics, health care, diet and nutrition, exercise, lifestyle and crime rate.

In the past, the average life expectancy of countries in different regions and countries with different levels of civilization also differed. In some developed countries, most people live to 70-90 years. In some developing countries, the average life expectancy is much lower, only 0-80 years, which is a relatively large span.

Numerous scientific studies have shown that longevity is based on two main factors: genetics and lifestyle principles.

According to the data, it is estimated that the length of human life is 20-0 related to individual genes, and the rest is determined by personal behavior and environmental factors, which can be adjusted and changed.

But even the longest-lived human beings have a life limit of just over 100 years. The longest human lifespan in human history reached 119 years.

Leave aside unnatural deaths such as accidents, diseases, etc. The universal life span of human beings is to survive for about 100 years, which is not a short life span in the natural world of the earth.

But when we look at the planets in the universe that humans have set foot in, this lifespan seems too short.

The data given by Ah Chen clearly told Chen Mengchuan that the lifespan of human beings is too short.

Among the known groups of intelligent life, the lifespan of humans is even lower.

On the blue planet 172 light-years away from the emerald starfish, there is a group of primates that resemble humans, and their individual lives far exceed those of humans!

Each of these primates, which has walked upright like humans, can survive for more than 700 years!

The longest known person in the entire group even lived for more than 100 years.

Such a life form is completely incomparable to human beings.

Such a long lifespan makes the human population on the cyan planet almost boil.

Almost all scientists can't help but wonder why these groups of primates, which look so similar to humans, have such a long lifespan.

After a long period of research, biologists on the planet have discovered that the DNA of these primates is very different from that of humans, and the diet and rest routine are also very different from those of humans.

The rotation speed of the planet Blue is much slower than that of the Earth, and it takes about 614 hours to rotate once, which is almost 25 times more than that of the Earth.

The slow rotation speed makes the growth environment of the creatures on the whole planet completely different from that of the earth, and the wonderful laws of nature make most of the creatures on this planet evolve many magical differences.

One of the most iconic is longevity.

The intelligent races of the blue planet are still in the extremely backward and feudal Iron Age, and the races are spread all over the planet, thousands of countries and tribal regions, large and small, and worship hundreds of gods.

The arrival of human civilization is also considered to be the arrival of the gods.

Many of the intelligent life groups on the blue planet are crazy about believing in human gods.

The civilization gap brought about by the power of science and technology, the technology of human civilization has nothing to do with the gods for them.

Under the intervention of human civilization, the entire blue planet, all the countries, regions, and wars between tribes were quelled, and the entire planet fell into peace.

All opposing voices were erased, and humanity took over all order on the entire planet.

After that, human civilization began to study the secret of the lifespan of these indigenous intelligent civilizations.

After the power of science and technology and time, the life code was slowly cracked.

Human civilization has finally confirmed the longevity code in it.

Today, after this operation, Xing Lao will be called a new human with the same lifespan limit of the intelligent life group on the blue planet.
