Dominate Marvel

When the Great Xia Empire was founded, the native population of the Central Region was counted as slaves, which amounted to no more than 200 million. Fifteen years later, the total population has reached one billion.

By the end of the 1980s, the population of this star's bloodline had reached 30 billion. In just sixty-five years, the population increased thirty-fold.

The growth of population is not just about material abundance. With abundant materials and vigorous encouragement of fertility, the population naturally increased rapidly, but not that fast.

The biggest reason lies in the increase in the average quality of the population - body and soul are just appearances, while wisdom, labor force and longevity are the essence.

The important factor in population growth is longevity.

The longer one's life span, the longer one's vitality and fertile age last. Based on the average quality of the people of the empire today, the average lifespan is over 400 years old.

Except for the immortal species, such as elves or some non-humanoid components, most of them are no different from the people of the empire. Adults reach adulthood at the age of twenty, and the average lifespan exceeds three hundred years, so there will be at least two hundred and fifty years of active life in between.

In the past, people became powerless when they reached sixty. Now she is two hundred and sixty years old and still capable of having children. The abundant material conditions allowed the empire's population to skyrocket, increasing thirty-fold in just sixty-five years.

Of course, as the average quality of the population increases, fertility inevitably begins to decline.

Ying Yi knew this very well. The more powerful an individual is, the more limited his or her fertility is. This is the natural balance rule of heaven and earth.

The weaker the child, the greater its fertility. The stronger, the weaker the fertility.

This can be clearly shown in the data from every census in the empire.

At the beginning of the founding of the People's Republic of China, men and women who were at the peak of their vitality could have nine children in ten years. By the twentieth year of the empire, the average fertility rate per unit time had dropped threefold. By the 80th year of the empire, the average fertility rate per unit time had dropped to ten times its original level.

In the past, a couple could have nine children in ten years. Now it will be extended to one hundred years. Even if the creation of human beings does not stop, it will take an average of ten years to give birth to a child.

Fortunately, the childbearing years continue to be longer, and on average, each couple still has more newborns within the childbearing age.

The Empire is the economic, cultural, and political center of the Empire. Women from all walks of life still hope to marry there. In addition, the war continues and a large part of the captive female slaves from the newly conquered world end up on the Empire's own planet. This makes the Empire's own planet have an average of seven or eight wives and concubines per man, and as many as dozens of wives and concubines.

This is also a reason for the population explosion.

However, according to the budget of the Ministry of Civil Affairs, the population growth rate of the empire will drop to 500 million every year starting from 1981, and as the quality of the population continues to improve, the number of newborns will also decrease. , will eventually drop to an average of between 100 and 200 million per year, and eventually stabilize.

The key to stabilization is human potential - according to the research of Yuan Qi Palace, the potential limit of any kind of creature is 20 if the activity level of Yuan Qi is not limited. In other words, the average quality of the people of the empire will never exceed the number 20, no matter how the Yuan Qi activity of the world under the empire increases.

In other words, there is a limit to the average lifespan of a creature. The fertility rate also has a limit. On the basis of this limit, it is possible to calculate the stable range of the empire's future population growth.

Ying Yi understands very well.

Because he has experienced this himself.

Even if a great character is added to his body, his physical and soul statistics will stop at 20 before he can break through the shackles.

It is clearly a basic limit of the rules of the universe. Unless you have the guts to break through the shackles of potential, it is natural to take 20 as the limit.

When the physical and spiritual data both reach 20, the limit of human lifespan will be stable at about 1,200 years. Depending on their physical differences, the limit is one thousand two hundred and ninety-six years, but as long as it is not affected by injuries or congenital diseases, it will not be less than one thousand two hundred years.

This extreme data is valid for any intelligent creature. Even elves and dragons cannot exceed this limit.

Such is the limit of the rules of the universe. It is impossible for a race where all the people are immortal. This is a huge pressure on the nature of the universe.

Therefore, only a very small number of people, who are blessed by nature and have a good foundation, can break through the shackles.

This is the so-called glimmer of hope.

The mainstream of the universe must be endless reincarnation and reincarnation. Only in this way can the vitality and vitality of the universe be maintained on a cosmic scale. If the mainstream only lives and does not die, the universe will eventually become a pool of stagnant water.

Ying Yi sometimes thinks of some myths and legends. The calamities and killings in the legends are probably an adjustment of the universe's vitality.

In those myths and legends, each race is immortal. When the number increases to a certain level, it will put huge pressure on the universe itself. That's why there are calamities of measurement and calamities of killing.

Let them fight each other, kill each other artificially, and reduce the number of immortals. Let the mainstream of the universe regain the vitality process of the natural cycle of life and death. This is probably the essence of killing and measuring tribulations.

"For a living being, a life span of 1200 to 300 years should be enough." Ying Yi smiled and said: "In the loess of a hundred years, a lot of wisdom returned to heaven and earth without being displayed. It is a pity. Wisdom dies after a thousand years. To be publicized without putting pressure on the nature of the universe, this is the beauty of Tao."

"Since ancient times, living beings have sought immortality and immortality. Even the emperor with great talent and sagacity cannot break away from this knot." Zi Niang leaned against Ying Yi and said, "I'm afraid it will be the same when the people of the empire have developed to that level."

Ying Yi smiled and said: "Isn't it just right? Give them a goal that they can never achieve and escape from, so that their wisdom can be used to its fullest. This is a good thing for the empire itself."

Zi Niang whispered: "Your Majesty is immortal, but after a thousand years, I will leave you..."

Ying Yi sighed softly and patted Zi Niang on the shoulder: "Don't think too much. You and I are only a hundred years old now, and it's still early to reach the end of our lifespan."

Having said that, Ying Yi knew that Zi Niang was under pressure.

Ying Yi has deep roots, has broken through the shackles, and has already exceeded the limit of his lifespan. But Zi Niang didn't. If that's all, that's fine. The key is that in Ying Yi's inner palace, there is a concubine with the same character. This caused a lot of psychological pressure on Zi Niang, the empress.

In fact, not only Zi Niang, but also some other concubines had the same words when getting along with Ying Yi.

But Ying Yi never answered directly.

But Ying Yi actually has a way - this method is very harsh, but it can indeed bring out the root of the problem and allow people to break through the shackles.
