Now these marks, in the calm and safe birth process, are no longer superimposed and strengthened, and gradually disappear on their own.

"So, today's babies can develop to real maturity and then send out the signal 'I want to be born'." Lanze concluded.

"So it used to be 'ten months of pregnancy', only about three hundred days?"

"It's about 280 days. A head circumference of 300 days won't be born. Which one of us is the woman?"

"Aha? Most people don't know this, right? Don't they take two years to raise a child in a nursery?"

"About 610 days, less than two years."

"It seems you have a lot of research?" Sister Hehua was a little embarrassed.

Xiaolan smiled slightly, stopped talking, and concentrated on crossing the road.

The woman who died had long been unable to give birth normally because she had been pregnant with the child for too long.

Whether nurseries and in vitro parenting are seen as a blessing for women, who account for half of the population, or as a catastrophe for all mankind, the current generation in China has been unable to get rid of nurseries and cannot return to the original way of childbirth.

A hundred years ago, the Great Shenzhou was suffering from a long-term economic recession: the shrinkage of the labor force caused by the birth of women of childbearing age was accompanied by the economic decline, and the difficulty of women of childbearing age leaving their jobs led to the collapse of the total population quantity and quality.

Cyclical fluctuations have caused the population and economic conditions to fall into an inescapable decline trap.

The ultimate way for Da Shenzhou to escape from the trap is: in vitro parenting.

To be precise, it is the popularization of in vitro parenting guaranteed by the national welfare system.

Before being included in social welfare, commercial in vitro parenting services had been popular in China for several years. When this industry first appeared, it mainly catered to the rich around the world. But perhaps because of the inborn defects of the human race, this industry

The booming development has taken place in several countries in Eastern Asia that have long suffered from negative population growth.

East Asian and North Asian races have the longest average gestation time of babies, the largest birth head circumference, the lowest twin rate, and the highest natural dystocia rate. Therefore, women are unwilling to give birth to children. They are more afraid of giving birth than women of other races.

The shortcomings of babies are also obvious after birth. It takes the longest time to learn to walk, dress independently, and eat independently. It takes the longest time to need round-the-clock personal care.

Of course, this race has its advantages. For example, adults have the largest average brain capacity. But what’s the use?

Adults cannot conjure things out of thin air.

First there has to be a baby.

In terms of natural pregnancy, African women have the best fertility performance, with the highest twin rate and the fastest babies to become independent. European indigenous races also perform well.

After Da Shenzhou established a systematic in vitro parenting system, it not only reversed the dual dilemmas of economic recession and population collapse, but also began to provide a high-quality talent reserve based on a large population base for the development of space.
