Sing?

What song are you singing?

What sing?

A family of four with one husband and one wife...doesn't this sound a bit wrong?

Qin Xiaolu's hair exploded, his hands shook, and an ominous premonition suddenly appeared in his heart.

He opened the panel tremblingly, and searched for information about the Yu clan on the search page of the Myriad Realms system.

Because he has already signed up for the Myriad Worlds experience event, the system has opened some permissions to the players who participate in the event, so they can learn about the world they are about to enter in advance.

It doesn't matter if you look at it, Qin Xiaolu's back is instantly soaked, and the cold sweat can't stop flowing.

The background world of Sky City is located at JD68, JSHK88,76,443, 10238, [-]. It is a medium civilization developed by the Yu tribe, which has existed for [-] years so far.

Since the age of ignorance, the ancestors of the Yu tribe have stood out in the evolution, developed their own wisdom and civilization, and firmly occupied the top of the food chain.

However, the evolution process of the Yu people is different from other creatures. Evolution does not mean the improvement of ability, but the sacrifice of individual combat power in exchange for the peace and reproduction of the population.

According to the archaeological records of the Yu clan, the ancestors of the Yu clan were once the most powerful creatures in the θ galaxy. They were huge in size, violent and aggressive, and started wars in the sky, sea, and land at any time. Other giant beasts could not compete with them.

Especially the Phoenix family, which is regarded as a god by the Yu family, is said to have the power to destroy heaven and earth by waving its wings to rain down a sea of ​​flames.The appearance of the phoenix completely ended the chaotic and ignorant period of the Yu clan, gathered the wild ancestor of the Yu clan under its wings, and established a wisdom civilization.

But legends are legends. The Yu clan has developed for 1 years, and the Phoenix clan only appears in legends, and no evidence of its real existence has ever been found.However, despite the establishment of civilization, in the early days, because they could not get rid of the plunder and possessiveness in their nature, the internal friction of the Yu clan has always been a big problem hindering the reproduction of the species.In order to compete for resources and reproductive rights, there are a large number of casualties of the Primordial Feather Clan every year. Many chicks destroy the eggs because other male birds want the female birds to enter estrus again.

As a result, a strange phenomenon appeared in the development history of the θ galaxy creatures. The top predators, the Yu clan, established civilization and had no natural enemies. For a long time in the early days of civilization, the population continued to decrease.In the case of no battle damage, the survival rate of newborn cubs is always at a low level. Coupled with the internal friction every estrus, the development curve of the Yuzu has a terrible negative growth. If this continues, it will not be far from extinction .

Probably it was the phoenix, at the time of the life and death of the Yu clan, the fate suddenly took a turn for the better.

There is still no record in the data, but at a certain point in history, the Yu family suddenly changed the courtship mode, from life and death fighting to singing and showing feathers, and the female bird agreed to obtain the right to mate.

Regarding the reason for the change, some people say that the birth of the phoenix forcibly changed the rules of race reproduction.

But more researchers believe that this is the law of natural selection.During this period of time, a certain scum bird with a genetic mutation was able to eat soft food but hard to eat. With its beautiful feathers and sweet words, it tricked countless female birds to follow them wholeheartedly. It swore to the death that he would not be killed by other birds, and left behind countless cubs.

Seeing this scene, the male birds were greatly shocked. In addition to being angry, they also found that singing and flaunting feathers are safer than fighting, so they followed suit.But in this way, the direction of reproduction of the Yu clan has changed.Originally, only the most powerful Yu Clan could leave offspring, but now the beautiful and singing birds also have a chance. The Yu Clan sacrificed their individual abilities in exchange for the peaceful development of the entire race, which has been thriving until now.

But in the end, it was a once powerful creature, and the pursuit of power in its bones has never stopped.In the middle ages, wars among internal species broke out, and the bloodline awakeners appeared on the stage of history for the first time, and the power division of the Yu clan was reshuffled as a result.

Awakened bloodlines possess stronger bodies and fighting power than ordinary Yuzu, with exceptionally good reaction speed and judgment. They are natural warriors and have successfully established their own political power in wars.

The new nobles who are awakened naturally know the benefits of blood, so in order to consolidate power, they began to induce it artificially.About two-thirds of the ordinary Yu clan awakened their blood, no matter which race they belonged to, their abilities were more or less improved.However, the remaining one-third did not move. No matter how hard they tried, they could not awaken their bloodlines. They were called the silent species and gradually became the bottom of society.

The children of the awakened and the awakened must be the awakened, and the combination of the awakened and the silent species has a chance to give birth to the silent species, so the combination of the two was banned by those in power from the very beginning.

But this is just the beginning.

The deeper the degree of awakening is bound to identity, status, and ability, the more fanatical the Yuzu will pursue the purity of blood.For a long time afterwards, marriages were only allowed to occur between awakened people of the same level and race. Birds of prey and weak birds could not combine, and eggs could not be legally laid if the deviation of the awakening degree reached more than 5%. Can become an unrecognized illegitimate child.

The effect of this operation is obvious. The blood purity of the awakened members of the Yu clan has been rapidly improved, and society has also entered a period of rapid development.

When the formation of the first awakened legion was completed, the expansion of the Yu clan's power officially began, known as the "Pioneering Era" in history.At this point in time, the interstellar spacecraft of the Yu clan left the parent star for the first time and flew into deep space, provoking wars over resources one after another.Awakened people with high bloodline purity are war machines, possessing the incomparably tyrannical power of the ancestors of the Yu clan. Their hidden violence and ferocity are activated, and they kill freely in blood and fire. galaxy.

However, it was here that fate took another turn.

First, two high-ranking nobles combined to give birth to the awakening egg. The bloodline purity of this egg was over 80% according to the instrument test, which is the purest bloodline record in history.But before the Yu clan could celebrate for this proud son of heaven, the egg exploded, and the unformed cub died instantly because it couldn't bear the restlessness of the blood, and the egg piece even injured one of its fathers.

It was only then that the Yu people discovered that the return of the bloodline brought about not only an increase in strength, but also a crisis that had been silent in the genes for thousands of years.

The strength of the ancestor Yuzu matched its powerful physique, which was a burden for the degraded modern Yuzu.Once the limit is exceeded, the power in the blood will cause restlessness, and the severe pain and violent desire will wash away the consciousness of the awakened person, making them manic and aggressive.If there is no way to control it, the awakened person will explode and die like that bird egg.

This explosive discovery almost collapsed the world of Yu Clan, and countless Yu Clan who had awakened their blood rushed to the Academy of Sciences, demanding an immediate solution from the chief scientist.The aristocrats who used to be aloof were even more insecure. Numerous engagements were cancelled, and husbands and wives turned against each other. On the contrary, the silent species who had been suppressed at the bottom of society was grateful to the gods for the first time, and no longer cursed the injustice of fate.

Under the high pressure of life and death, the scientists of the Yu clan burst out with super wisdom. It took only one month for the solution to the blood restlessness to be made public.

In fact, the method is very simple, as long as the awakening degree of the bloodline is discarded and the biological instinct is followed to reproduce, the singing of the feather clan will naturally help the awakened person to calm down the violence, restore sanity and suppress energy restlessness.The higher the degree of relationship, the better the healing effect, especially the singing during the estrus period. Therefore, it is recommended that the two parties form a legal partner, live together and have children.

This plan has completely overturned the hierarchical marriage system of the Yu Clan that has been passed down for hundreds of years. It has been hailed as the beginning of the era of "free marriage" by historical materials. Countless Yu Clans came together because of love and liking. Explosive growth.

But this is only limited to ordinary people, and the nobles who have social power and resources are not excited.Successively, several nobles calmed down their blood agitation through singing, but it was the low-level feather clan who helped them, and one of them was the silent species.Laying eggs with such a person will inevitably lower the level of the family's descendants.

Not having outstanding descendants means that the existing power cannot be grasped, resources will be squeezed out by other families, the wealth accumulated by the ancestors will be lost, and eventually they will be reduced to common people.

None of the nobles could accept this result, so they racked their brains and came up with a solution, which was the "branch" plan.

After reading the content of the "branch" project, Qin Lu finally couldn't bear it, grabbed a stone and threw it into the sea.

Still puzzled, he threw two more stones, until the stones were completely swallowed by waves, and his heart gradually recovered.

The so-called "branch" plan is a variant of the concubine system, which nominally allows the silent species at the bottom of society and the low-level feather clan to combine with high-level nobles, but in reality these people have no status at all, and are called escorts, just to appease the master It's just a tool for the blood to go berserk.

Because singing during estrus is the most effective, these "Teng concubines" often have relationships with their masters. Although the eggs they lay are recognized by the family, they are not equal to the offspring of real high blood couples, and their status will be much lower.

But no matter what, becoming an escort is a shortcut for the silent species and the low-level feathered race to enter the upper class, and the law also gives them certain protection, so many people are still tempted.

After years of publicity and subtle influence, the Yuzu has developed a complete escort training process, and has a mature supporting industry. The society has once again entered a stable period because of this deformed marriage system.The Feathers also refocused their attention on territorial expansion and internal strife.

The Birds of Prey faction and the Alliance of Weak Birds competed for colonial autonomy in the parliament, and the legions of the three major families went their separate ways. Qin Lu and Xi Ren are going to enter such an era, where stability, prosperity, and superficial prosperity are turbulent, and there is a possibility of a comeback at any time. .

As a silent species that cannot change into a bird, the battle in the world seems to have nothing to do with them.

However, let Xi Xiaoren be someone else's concubine, and stand by and sing while others are doing business...

Qin Xiaolu shuddered, feeling that the scene was slightly bloody and violent.

"Ahhh, so annoying!"

He scratched at his hair desperately.

What a shit plan!They have entered the interstellar era and even drove back to the feudal society, the bird tribe is really unscrupulous!

Originally thought he chose a relaxed modern world, but in the end he won a wonderful draw, how could he tell Xiaoren about this?It can't be said that we used to be maids for others, right?

If it didn't work out, he had no choice but to flee into the mountains with a small blade, to survive in the wild, which was much better than being chased and killed by the world.

As for the module or something... don't have to think about it this time.Anyway, there is no reward for completing the task, just treat it as a field trip!

The author has something to say:

This background needs to be introduced carefully, because it has something to do with Xiaoren
