The appearance of the Virgo aliens, because of the reduction of the pain of life and reproduction, they devoted their whole lives to scientific research, especially the study of biotechnology and the exploration of the universe, so that this life form broke through the barriers of time and space, and established a survival base in various stars in the universe, which was very prosperous.

In addition to the unisex people who evolved from ordinary humans, the emergence of the Zerg has become a direct competitor to compete with the unisex people for resources.

The Zerg have taken different evolutionary paths, and they have evolved through the evolution of DNA-generated body structures and survival instincts.

Female and male Homo sapiens have a sense of self comparable to that of monosex, and are scarce in number; Other worker insects only have a weak sense of self, no gender distinction, and their sensory organs are not sensitive, and they act according to the instructions of the female insect and the male intelligent worm, which is the cornerstone of the survival of the largest number of insects.

The mother worm is the queen of a colony, and is responsible for reproduction and planning the reproduction of the population. Male Homo sapiens can change their own body structure to adapt to different living environments, and change their DNA through an infinite number of experiments in their interaction with the environment, and these DNA evolved by interacting with the environment, after they mate with the mother, they can give birth to insects that can adapt to a specific living environment.

For example, on a planet full of carbon dioxide due to lack of oxygen, the first generation of Homo sapiens adopted the survival mode of plants through the evolution of their own physiological structure, creating a body structure that inhales carbon dioxide and exhales oxygen, and carries out photosynthesis. It then mates with the mother to produce insects that can survive on a planet full of carbon dioxide.

This evolution of DNA life allowed the Zerg to multiply in large numbers across the stars. For example, in the universe where there is no air, they can evolve into strong air sacs with their own air, and the sleeping Homo sapiens in this air sac can cross the barrier of space and reach a place suitable for the survival and reproduction of insects, in addition to mating with the female worm, they can also reproduce parthenogenesis by themselves, or mate with other Homo sapiens insects in the same sex, and reproduce the first generation of female worms that can adapt to a certain environment, so as to establish a complete population of the Zerg and open up the living space of the Zerg.

The Zerg insists on maintaining an ecosystem of "love and sacrifice", but it is simplified to an ecosystem where only various plants, insects and microorganisms depend and grow together, that is, the backyard of the Zerg.

The Zerg are fed by self-grown crops, mainly vegetarian diets. When the living environment of a certain planet needs a certain kind of animal protein, the insect will dominate the ecosystem, design plants or insects with this animal protein, record the life form with this animal protein, and then produce the food needed for this life in the mode of farming.

They have no human feelings, no literature, no music, no art, only the mutual transformation of plants, microorganisms and zerg in the ecosystem, and the way of reunion in "love is still bonded" is limited to the way of "meeting in the water", "eating" and "being eaten", exchanging DNA and living together.

The pain of life of the Zerg is not complicated except for the death of the body and the impermanence of adapting to the environment in order to survive.

Except for a small number of female insects and male sapiens insects because they have a strong sense of self and need to consume more water resources, most of the worker insects are microorganisms and do not have a strong sense of self, so they only need to consume a small amount of water resources.
