Previously, it was basically the normal social background Yu Miao was familiar with. The only two differences were the orc world and the ancient world.
But it can be considered fun.
Yu Miao did not expect that this time the main system directly threw her into the future world.
The past of this world can be regarded as the parallel space of the modern society that Yu Miao has experienced before.
Only in more than 3000 A.D., a serious crisis appeared in the ecological circle, and the home planet of human beings - the earth, ushered in a period of catastrophic outbreak.
All kinds of natural disasters and man-made disasters gathered during that time, the living space was gradually reduced, and the population began to drop sharply.
In the later stage, the countries on all continents have formed a whole, no longer exist as different countries, and unite to overcome this difficulty.
In the end, with the strength of all people, several spaceships were built, carrying the survival resources collected by the last living compatriots, they flew into space desperately, and reluctantly left this planet that gave birth to human civilization.
The five spaceships at that time were called Noah's Ark 1, 2, 3, 4, and 5 respectively.
Among them, No. 4 and No. 5 are not as good as the previous three because they are in the late stage of manufacturing and lack of materials. After a long flight, they have no choice but to disintegrate before finding a suitable landing place.
Just in time for the cosmic turbulence, the passengers on the spaceship didn't even have a chance to survive, so they were involved and sacrificed.
And the other three "Noah's Ark" were lucky.
At the last moment when the dye was exhausted, they actually found a planet that was very similar to the earth by mistake, allowing the humans on the three spaceships to survive successfully.
It's just that there are no two identical leaves on a tree.
Of course, it is impossible for two identical planets to exist.
Although this planet, known as the "Star of Hope", provides a suitable environment for human beings to survive, it is different from the earth.
Moreover, the magnetic field environment is very special.
In the long history of human existence, the body of human beings has also been imperceptibly changed by the magnetic field, and it is gradually different from before.
? In addition to the rapid advancement of technology, the physique has also been further improved.
The most obvious and extreme change is the gender of human beings.
In the past, the races on earth were divided into male and female.
However, after the first year of the Star Era, they were divided into six different genders.
Generally divided into three categories: alpha (alpha), beta (beta), omega (omega).
These three categories are divided into men and women.
Male alpha and female omega have almost the same reproductive structure as earth males and earth females respectively.
However, human beings of the other four genders have both male and female reproductive systems, but there are differences in strength and weakness.
Beta is in the middle, the pheromone is very stable, will not be affected by other external factors, and the living environment is normalized, it can be regarded as the existence of several genders.
The fertility rate is also at an average level, and the child born after the combination of two betas has a high probability of being a beta.
Both alpha and omega have pheromone infection and will be attracted by each other's pheromone. This kind of love can be called "biological response love", or it can be said to be a more intuitive physical impulse.
There are glands on the back of the omega's neck, and when it is in estrus, the pheromone breath it emits will attract alpha riots.
This gland can be marked by alpha. After being marked, the pheromone of omega will tend to be stable and no longer strongly attract other alphas. (Remember the site URL: www.hlnovel.com
