The Zerg were born on a terrestrial planet called 'Tyr', which has no oceans, only lakes scattered throughout the planet, and the Zerg were originally bred in these large and small lakes.

However, the Zerg of that period could not be counted as a Zerg, but a brute beast without intelligence, from a single cell on the microscopic scale to various creatures on the macroscopic scale, deceiving, fighting, and camouflaging...... In order to survive, it is possible to do everything to survive, and it can be said that other species with complex biospheres are also the case with this planet.

Every once in a while, Tyre is exposed to ionizing radiation, which is not very strong, and only destroys the genes of a wide range of organisms.

The reason for this is that the massive object around Tyre is not a star, but a neutron star with a relatively slow rotation, and the pulse beam of the neutron star does not directly hit Tyre, but there is still diffuse ionizing radiation that reaches Tyre.

Even if the ionizing radiation of neutron stars is filtered by Tyr's atmosphere, and the radiation is weakened a lot, it is still inevitable that a large number of organisms will die due to radiation, and only aquatic life can survive, because the water body is also a natural radiation barrier.

The seeds are still there, and there will be aquatic creatures crawling up to land one after another.

Tyre is a planet with a land area larger than a body of water, and there is a wider living space on land, and as long as the survival instinct of the creatures on Tyr is not lost, they will not live in the lake.

Not afraid of life and death, just to survive!

After a long period of time, the extinction and reincarnation of land creatures again and again, there are finally creatures on Tyre that have evolved genes that are very resistant to radiation, and they have climbed onto the land to explore and conquer.

Although it has taken a long time for a gene to have a strong resistance to radiation has finally evolved, strong resistance is only strong, and does not mean complete immunity.

So, every time Tyre's rotation is towards a neutron star, and the side of the planet is daylight, the terrestrial life in that area mutates on a large scale.

Most of the mutations are very deformed, and even survival is a problem, but there are also a few creatures, which are very advanced in mutations, and they are the lucky ones who are the lucky ones who were smuggled into Europe by lottery.

Through the law of natural selection in the ecosystem, species that cannot adapt to survival will be lost, and under the big waves and sands, the biological populations on Tyre have become more and more advanced, and the rate of species evolution has far exceeded that of other planets with complex ecosystems, and the evolution of species on other planets is measured in 10,000 years, while on Tyre is measured in years.

On Tyr, a creature the size of an ant, with enough luck, could evolve into a powerful predator the size of a mammoth in fifty or sixty years, dominating one side.

However, in such a competitive environment, it is not easy for intelligent species to evolve, and the large capacity of the brain will occupy a lot of nutrients in the body, which will make it impossible for intelligent species to compete physically to overwhelm other organisms.

The manufacture of tools is not achieved overnight, and the accumulation of knowledge also requires a process, but the competition of living beings is all the time, and the rapid evolution brings about a far more fierce competitive environment than the ecosystem of other planets.

As a result, many of the intelligent species on Tyre who were selected for the 'Brain Expansion' were destroyed because they could not adapt to the fierce competition of creatures. 89 Literature Network

But there are exceptions to everything, a special kind of intelligent creature that has been conceived on Tyr and has gained a foothold in a highly competitive ecosystem.

They are the original prototype of the Zerg - the hive.

Similar to volcanic in appearance, the hive is responsible for producing worker bees and making food that can be easily digested by worker bees, and the worker bees are responsible for hunting and guarding the nest, and their relationship is similar to that of an ant colony.

At this time, there was no Zerg network, and they relied on biological pheromones to maintain their relationship with each other.

With enough nutrients and no need to participate in the fierce race for survival, the hive's wisdom is naturally turned on.

Before awakening to wisdom, the hives will exchange information with each other, because this can increase the probability of survival, even for wild beasts, communication is a very useful means of survival, such as lions and tigers on the earth, they will consciously leave excrement on the edge of the territory to warn invaders outside the territory.

Through pheromone communication, the pheromone is left on a worker bee, and the worker bee is used as a messenger to transmit 'pheromone letters' to complete the information communication between the hives.

The increase in wisdom means an increase in the complexity of communication, and the amount of information transferred between peers is increasing.

Such an information circulation network has built a primitive civilized society, and the hive in this social system is the command class of the original Zerg, and the most intelligent leader of the class is revered as the 'master'.

The power of the group is very strong, especially after the emergence of 'civilization', other creatures that are still in the category of 'beasts', and cannot fight against the Zerg at all, because the Zerg have successfully promoted to 'civilization', and have become the top and most suspenseful predators on Tyre.

However, no matter how powerful a creature is, it is very powerless in the face of natural disasters.

Reality slapped the Zerg awake from the dream of 'invincible in the world', an asteroid with a diameter of 30 kilometers struck Tyr, and the shockwave destroyed all living things in an area of Australia, and the Zerg there were not spared.

Dust clouds have covered the sky for 20 years, accompanied by 20 years of severe cold, ionizing radiation weakened by dust clouds, and the entire ecosystem has entered the era of 'evolutionary brakes', and I don't know how many powerful species are going extinct because they can't survive the cold.

All living things are so fragile in front of nature.

The Zerg almost perished because of this, if it weren't for the Juggernaut calling on all the same kind to command the worker bees to dig underground, so that the entire Zerg could hide underground and rely on geothermal heat to survive the severe cold for twenty years, I am afraid that the Zerg would have been extinct.

However, even if they hide underground and rely on geothermal heat to survive, the situation of the Zerg is not very good, because there is no food, and the extinction of a large number of species on the ground means that the Zerg have lost their food sources, and many insect nests have starved to death.

As for the Zerg that survived, it was because they were forced by the environment to learn to plant, and they lived underground for twenty years through a fungus plant that absorbs geothermal heat to produce bioenergy.
