"Yo, you're awake."

When he saw Yang Xi's entangled expression mixed with joy and pain, and walked out of the bedroom with a pink and kawaii silver-haired little loli, he was the first to see him, Saeko, who held back her smile and greeted him.

"Well, by the way, where are the others?"

"Everyone went out to guard the space passage."

"Safeguarding the space passage? Do you need so many people?"

"You don't know that when you were unconscious, three more space cracks appeared. After a day, these space cracks all expanded into complete and stable space channels, and creatures from another world were causing trouble in this world. If it weren't for my worst strength, and with your situation at that time, it would be impossible for me to have no one to take care of you, otherwise I would have gone to help."

"Wait...you mean, I was in a coma all day, and during this period, the space channels of this world have appeared along with five different worlds?!"

The large amount of information contained in Saeko Mushima's words surprised Yang Xi very much.

"That's right, and based on the data analysis detected by Lingling, these five worlds are named red, green, black, white, and blue."

"Uh~ Is it meaningful to name this?"

"Of course, the invaders who came from the Red World claimed to be the Apostles of the Red World. As soon as they arrived in this world, they devoured the power of human beings' existence unscrupulously, and then used the residue of the devoured human beings' existence to make a ball of burning torch to maintain their original memory personality and life-activity ability. Ordinary people seem to be as if that person is still alive. While consuming the remaining power, the relationship, residence, identity, and sense of existence of the devoured person and the surroundings gradually lost, and they completely disappeared when they reached the point where no one could stop it. With this disappearance, all traces that this person had once been eliminated and became non-existent."

Hongshi! Damn, I'm down!

Feeling that his arms were holding him tightened, the little loli in Yang Xi's arms knew that his heart was not as calm as he seemed.

"The Green World is fine. I heard Yaai, who had been wandering around the world, said that it was a different world in the primitive period, full of various prehistoric creatures. And looking down from the sky, it was full of green, and it was simply a green ocean, so Lingling simply gave it this name."

Speaking of this, Saeko Mushima shrugged helplessly for Huang Lingling's casual expression.

"Uh~ Ya Ai actually went in and took a walk. She still liked to do whatever she wanted as usual."

"No, everyone persuaded her at the beginning." On the issue of Zhu Ranya Ai, Saeko Mushima did not get too entangled and continued: "The Black World is the first space crack that appeared, located above Mount Everest. Just as the space channel in this place was completely formed, a large number of monsters rushed over. If it weren't for the Five Elements Array being laid out there, I'm afraid the world would have been in chaos! Because the monsters in this world were all dark, and most of them had corrosion and poisonous characteristics, Lingling decisively named the Black World."

"The White World and the Blue World are the least threatening of these five worlds. The residents of the White World are a group of angels living in heaven. They have actively contacted us and expressed their willingness to contribute to maintaining peace and stability in this world."

Seeing Saeko Mushima hesitant, Yang Xi smiled, "Even an angel is not a fool, it is impossible to do things in vain. It must have their purpose. Let's talk about it, what are their requirements?"

"Build a kingdom of heaven in this world and gain faith. But we did not agree directly, but waited for you to wake up and make a decision."

"So? Anyway, faith doesn't matter to us at all, so let's take our needs. With the help of these angels, we should be much more relaxed."

Saeko Mushima nodded, indicating that she understood.

"What about the Green World? You haven't mentioned this world yet."

"Ah, didn't I say that?" Saeko Mushima, who had just turned around and was about to leave, was slightly stunned.

"Girl, your eyes are erratic, don't think about making up lies and lying to me!"

Well, Yang Xi just made a statement and teased Saeko Mushima, and the little loli, who had been silent in her arms, stinged him with her nails.

It's really just a little bit, but why does it hurt so much?!

Hiss ~

After searching for a cold breath, Yang Xi smiled helplessly. He was reluctant to beat or scold the young lady, so he could only swallow his anger.

"Okay OK, if they ask, don't say that I told you the news."

"Yeah!" Saeko Mushima's mysterious look made her look even more curious. What exactly is this Qing Dynasty world that actually makes her relatives regard her as a beast and want to hide it from her.

"Well~ Actually, this Green World is a world of young and beautiful girls who will always remain young."

"No! This is unscientific!"

The lonely yin does not grow, and the lonely yang does not grow. How can a world of young and beautiful girls who only maintain youth exist?

"No, no, no, you were wrong this time. The Qingzhi World is not only scientific, but also their technological level is far beyond the most advanced technology we have mastered for three thousand years!"

"Three thousand years?! What about their reaction to the connection between the worlds this time?"

"...United. Join us and the angels of the White World to form an alliance to fight the invasions of several other worlds."

Since this world has become a public platform, no matter which world masters this world, it is equivalent to mastering the channel to several other worlds. Therefore, union is inevitable, and the key is who unites with whom.

However, for some reason, Yang Xi always felt that Saeko Mushima looked at her strangely.

"I...is there something wrong with me?"

"Forget it, you will know it in the future anyway, so I'll just say it."

Sighing, Saeko Mushima looked like she was giving up. "The Green World was originally a pure technology world like this world, but because of the increasing advancement of technology, men had disappeared about a thousand years ago."

The reason why men are male is determined by the Y chromosome. However, although men are strong, their Y chromosome is weak. Research in recent years has found that the Y chromosome unique to men is dying. 300 million years ago, the Y chromosome had 1,438 genes at the beginning of its birth. However, there are only 45 genes left today. According to this rate, the Y chromosome will completely disappear in 10 million years.

Chromosomes are vectors of genes. There are 23 pairs of chromosomes in human cells. These include 22 pairs of autosomes and 1 pair of sex chromosomes. The sex chromosomes include X and Y chromosomes, which determine the gender of humans. The sex chromosomes of men are XY, while the sex chromosomes of women are XX.

Compared with the hardworking and powerful X chromosome, the unique Y chromosome of men seems lazy and short. Not only is it less than one-third of the X chromosome, but most of the DNA sequences are infunctional. The genes involved in the "work" are even less than one-tenth of the X chromosome. Genes determine the various characteristics displayed by organisms, and their number can reflect the "influence" of chromosomes to a certain extent. Therefore, the Y chromosome lacking genes seems to be very weak.

However, the Y chromosome also has its own core competitiveness, and its existence is of great significance to the determination of human gender. Its ace is the SRY gene. The SRY gene, also known as the testicle determinant, is a protein expressed in male gonads. During the sexual differentiation of the embryo, the SRY gene stimulates the primitive gonad to develop in the direction of the testicles, and then the initial testicles begin to secrete androgens, mainly testosterone, which stimulates the male embryo to develop in the direction of masculinity. Without the stimulation of the SRY gene, the primitive gonads will naturally develop in the direction of the ovaries, and then the ovaries secrete estrogen, stimulating the female embryo to begin to develop female sexual characteristics. It can be said that without the SRY gene, there will be no men in the world.

Except for the Y chromosome, other chromosomes, including the X chromosome, all exist in pairs. The two chromosomes that exist in pairs are "backup" each other and can eliminate mutations that harm their own genes. When meiotic cells divide, if one of them has defects, the error can be quickly corrected and repaired by comparison with the backup. However, the "narcissistic" Y chromosome does not control and correct the error with the companion X chromosome.

The result of closed and conservative is self-destruction. Over millions of years of evolution, the number of genes on the Y chromosome has been decreasing, which has almost become an irreversible trend.

I always feel that the Green World is the future version of this world. A world with only women!

Because of the super advanced technology, artificial cultivation of the next generation is no longer a problem. In addition, biotechnology that penetrates into cells allows new babies to not only not have to worry about genetic diseases or congenital diseases, but also can grow healthily and quickly under scientific care.

But... another problem arose.

Because these children have come into contact with the most from childhood to adulthood, not humans but machines, which leads to their extreme lack of emotions. Everyone seems to be a robot with exquisite but lifelessness.

Because of the lack of feelings, there are no elderly people in the Qingzhi World.

Because in a ruthless world that emphasizes efficiency, there is no need for borers or waste. Therefore, most people are passing through the golden stage, and their physical functions begin to degenerate and are destroyed!

This is also why there are only young and beautiful girls in this world.

Of course, what Yang Xi even more unexpected is-

"The alliance of the Green World is also conditional, that is, the best male genes in our world are used as samples to allow them to cultivate a better next generation!"

"Damn, I'mn, Mengxiang, don't keep slapping me?"

After Saeko Mushima finished speaking, before Yang Xi could say anything, she was tingled by the little loli in her arms with her cheeks puffed.

Well, this little girl is Akaxia Mengxiang, who can only barely maintain movement after being sucked away most of the blood by the unconscious Yang Xi.
