"Of course~"

The old man nodded as a matter of course.

"If you look at the history of your human development, with the continuous improvement of the level of civilization and technological development, the lifespan of your human beings on the earth has begun to increase significantly."

"In the case of China, in ancient times, the average life expectancy of people did not exceed 35 years old, but in the 21st century, the average life expectancy in China has now reached 76 years old, and the country with the highest average life expectancy in the world is Japan at 84 years old."

"Life expectancy is also an important indicator to measure the level of development of a civilization!"

When he heard this, Qin Yi also nodded, the United Nations Development Programme publishes a global development index every year, which has many indicators, such as economy, per capita education level, life expectancy, etc.

Generally speaking, the higher the life expectancy of countries and regions, the higher the development index, the lower the vice versa, the index of developed countries in Europe and the United States is basically in the forefront, while the countries in Africa are basically at the end of the crane, the life expectancy in these regions is very low, and the average life expectancy in a very small number of areas is even less than 50 years old.

"The length of the average life expectancy of a civilization directly determines the height and online development of this civilization, you must know that the further technology develops, the more complex it becomes, if the life span is too short, it is very likely that you have not even finished learning what your predecessors have studied, you are already dying."

"In terms of your current Huaxia, the average life expectancy is 76 years old, and the first 20 years old have not graduated from college, and then a master's degree and doctorate, basically to 30 years old, at this time is in the peak of the golden age, to about 60 years old, almost 30 years of the best period."

"But once you reach the age of 60, people's physical fitness plummets, coupled with the aging of the brain, in the high-intensity scientific research work, there are fewer and fewer people who can contribute."

"This is only the level 1 civilization stage, once you enter the level 2 civilization stage, technology and knowledge will explode again, and it will take more time to learn, and if the average life expectancy is not extended, this means that the most golden time period will be greatly shortened."

"At that time, it will take longer and more difficult to develop from a level 2 civilization to a level 3 civilization, even if you can enter a level 3 civilization, if you want to enter a level 4 civilization, it is basically impossible."

The old man seems to be incarnated as a teacher, and he talks about this part endlessly, as if standing on the shoulders of giants and seeing the future of civilization development.

Hearing this, Qin Yi had to nod his head in agreement with the old man's concept after thinking for a long time, the development of modern science and technology is becoming more and more refined, and it is becoming more and more specialized, one of the most important reasons for this is the explosion of knowledge and technology, a person's energy is limited, and it is difficult to make outstanding contributions in many fields.

Therefore, it is better to choose a detailed field for research, and continue to expand and deepen in this field.

Of course, there has been no shortage of geniuses since ancient times, and some people are also very outstanding even in many fields, but this kind of people are a minority after all, and most of them are actually very small from each other.

"Another place that limits the development of civilization is the degree of development of the brain, in the case of your human beings on Earth, the number of neurons in the brain is about 86 billion to 100 billion, and the proportion of real development and use is only in single digits, which is about 6%-8%."

"Albert Einstein, one of the greatest scientists of the last century, only developed about 15% of his brain, but he developed the theory of relativity and made important contributions to the development of modern physics."

"From here, we should know the importance of brain development, it is said that Einstein's learning ability is very terrible, it is nothing to remember, he is very sensitive to numbers, and has an extremely powerful and terrible mental arithmetic ability."

"In the interstellar universe, the average life expectancy and the degree of brain development per capita are important indicators to measure the level of development of a civilization.

Then, the old man shifted the conversation to the degree of brain development.

"In that case, aren't all the high-level civilized citizens in the universe old and immortal?"

Hearing this, Qin Yi couldn't help but pout, this old man seemed to look down on the earthlings a little.

"Old and immortal? You'll find out later. ”

The old man smiled and said undeniably.

"With a high degree of brain development, the learning ability is very strong, and the same knowledge and content may have been integrated by him once he reads it, but it is still difficult for others to understand it after spending many days and nights studying."

"With the development of civilization and technology, there are more and more science and technology and knowledge, and it is becoming more and more difficult, although there are geniuses, but geniuses are very few after all, and the development of civilization and science and technology cannot be said to always rely on geniuses to promote, that is too slow, not to mention that geniuses may slowly disappear in the process of growth."

"If a civilization wants to develop, it is natural to improve and develop the overall level, so it is necessary to find ways to improve the average life expectancy and brain development of the whole citizenry."

"So under the research of countless civilizations and countless scientists, the civilizations in the universe have also slowly developed some technologies to develop the body and brain, and one of the most important products is genetic optimization liquid."

"Genetic Optimization Solution?"

When Qin Yi heard this, his eyes lit up all of a sudden, this thing sounded very tall.

"Genetic optimization solution can slowly improve the physical fitness of the human body, and can also slowly develop the human brain, so as to achieve the purpose of increasing the average life expectancy and improving the degree of brain development per capita."

"Of course, with the current level of human civilization on your earth, you can't make it at all, if you want to make a genetic optimization solution, even if it is the lowest level of genetic optimization liquid, your biotechnology needs to reach the level of a level 2 civilization."

"Isn't that what you said in vain, I thought you had such a good thing in your hands."

Qin Yi pouted, this old man is talking nonsense about some boundless things, now the civilization level of the earth is only level 1, and if he wants to develop to level 2 civilization, he doesn't know that it is the year of the monkey and the month of the horse, maybe he will have become a pile of loess by then.

"Haha~ Of course I have genetic optimization liquid in my hands, otherwise I wouldn't have said this, there are a lot of good things in my hands, if you want to get the good things in my hands, study hard, and continue to improve your civilization level."

When the old man saw Qin Yi's expression, he immediately laughed happily, and with a shake of his hand, there was an extra test-tube-like thing, which was flowing with amber-like green liquid.

"Really?"

When Qin Yi heard this, his eyes stared at the test tube, looking at the green liquid inside.

"No, the tech tower is in my brain, how do you get this thing out?"

Then Qin Yi seemed to think of something, and immediately frowned and said.

"Hehe~ The technology tower is beyond your imagination, and the technology involved in it is completely beyond the scope of your current understanding, wait a minute, as long as you think about it, I will take out this genetic optimization liquid for you."

"This time it's also to lay a foundation for you, it's given to you for free, and you still need to get good things in the future, so you have to study hard and master more technology and knowledge."

The old man said with a smile.

After listening to this, Qin Yi's consciousness returned to reality, and he thought of genetic optimization liquid in his mind.

Soon, in front of Qin Yi, a test tube appeared in Qin Yi's right hand, without a little fluctuation and sign, very abrupt, if Qin Yi hadn't been prepared, the whole person would have been startled, and it was very likely that he would instinctively throw away the things in his hand.

Qin Yi picked up the genetic optimization solution and looked at it carefully, like a glass of jade, exuding a touching green light, which vaguely made every cell in Qin Yi's body become restless, as if he wanted to devour it very much.

"Old man, how should I use this genetic optimization solution?"

With the genetic optimization solution in hand, Qin Yi didn't even have anything to hesitate, not to mention that at this time, every cell in his body was transmitting a strong signal to himself, and he immediately used this genetic optimization solution.

"It's very simple, you aim one end of the genetic optimization solution at one of your arms, and it will automatically inject into your body."

The old man's voice sounded in his mind, and at the same time, a video automatically appeared in Qin Yi's mind, seeing with his own eyes that a person is teaching you how to use this genetic optimization solution.

Qin Yi held the genetic optimization solution in his right hand and aimed it at his left arm.

I saw that a needle slowly appeared on the original test-tube-like container, and the needle was gently inserted into Qin Yi's arm, and then began to slowly inject genetic optimization solution into Qin Yi.

"Ah~"

Qin Yi didn't feel a trace of pain, on the contrary, as the genetic optimization solution was slowly injected into his body, Qin Yi only felt that his whole body had become extremely comfortable, very relaxed and comfortable, so that he couldn't help but make a comfortable sound.

His body is like the earth that has dried up for a long time, this gene optimization solution is like a heavy rain, as the rain falls, every cell in the body begins to greedily absorb the substances in the gene optimization solution, and even the mitochondria in the depths of Qin Yi's cells begin to change slowly.

"This feels so cool~"

For a long time, the genetic optimization liquid had already entered Qin Yi's body, and the test-tube-like container was very abruptly taken away by the old man, leaving no trace, Qin Yi felt that his body was very light, very comfortable, his brain was abnormally clear, and even the world around him became clear all of a sudden.
