Time point: a century in the future.
Human society has achieved great unity, and there are no differences in nationality. There are corresponding machines for food, clothing, housing and transportation that can be automated. The role of human beings is to optimize and maintain the sustainable development of this system so that it consumes less without reducing human material enjoyment.
Regarding innovation, for example, you can create new food through data simulation in the game, various experiments, analysis, and calculations. After confirming that it is harmless to the human body, it can be verified in reality. It may turn out to be a delicious dish, but it may also turn out to be unspeakable.
Regarding reproduction, humans have mastered the technology of cultivating biological embryos in vitro. Under the rules of ethical eugenics and eugenics, humans of all genders and ages can create a child by combining two germ cells. According to continuously optimized rules, only the total population within a period of time is controlled.
Gender differences are no longer obvious. Although there are still internal structural differences, when it comes to individuals, they can no longer be distinguished by personality traits, clothing, or even body shape.
Yunqi, an ordinary child, lives in a corner of such a world, living an "ordinary" life.
