fleet citizen

Yuan Yu was not in a hurry to leave Qiandao, but took Mint to the surface of Qiandao on a small space shuttle from the military space station.At this time, the area belonging to the Tavel Alliance on the ground of Qiandao was in the evening. It happened that Mint was tired after the emotional ups and downs of his first interstellar trip, so they found a base-class hotel to stay.

General Schmidt gave Yuan Yu a considerable amount of money for her travel expenses in Qiandao, but Yuan Yu did not go to the residential area of ​​the apex class, but settled in a small city with a complicated base class, allowing Mint Feel very strange.However, she seemed to be very interested in this small town, and after booking a hotel room, she went out for a stroll with Mint.

When I first arrived in Qiandao, looking at the surrounding buildings and streets with different styles from pearls and jades, Mint felt very novel at first, but after seeing more, I found that there is no big difference in essence from pearls and jades.Originally, the differences between the various planets were quite small, and the inhabitants of the current colonized planets almost all have mixed blood and mixed cultures from various ethnic groups in the era of the parent star, and the 200 years of isolation after immigration are not enough to develop a very Great difference comes from culture.

Unlike Zhuyu, the streets here are all B tribe people, and the living standard of Tavel base class seems to be higher than that of Zhuyu.The B people in Tavel, regardless of gender, wear all kinds of clothes with high-quality materials and reasonable designs that are not eye-catching. They walk at a moderate speed and often have a smile on their faces.Mint can't believe that a national alliance that doesn't have the entire planet's resources, and can only come second in the competition, can make their base class live so well, perhaps because they are more technologically advanced.

However, instead of discussing how advanced the technology of the Tavel Alliance is, Mint is still more concerned about the fate of the A people in this alliance.It's just that he couldn't directly ask about the ratio of A and B groups, so he asked Yuan Yu: "In the end, you decided to give them the technology?"

"Weighing the pros and cons, this is beneficial to the people." Yuan Yu replied, and explained, "If the Thousand Islands Federation gains an advantage on the new planet, then the overall living conditions of the base class on the new planet will be worse. Compared with Next, Tavel's army's commitment to improving the working environment and working conditions is worthy of our delivery of the technology of the transport ship. Besides, there are also some personal reasons, which make me personally trust Tavel more."

"You and that... General Schmidt?" Mint asked curiously, "Why do you trust him more?"

"Alumi is an old acquaintance of mine." Yuan Yu bought a glass of fresh fruit wine from a vending drink stand on the roadside, inserted a straw and handed it to Mint, "I saw him here for the first time, and then I found that this person was very sharp, but also upright and rational. Later, he established the Tavel Alliance by himself."

"What is this?" Mint looked at the strawberry and yellow peach pieces suspended in the light orange liquid in the glass, smelled it and found that it smelled of alcohol.

"Fresh fruit wine, a traditional specialty of Qiandao." Yuan Yu introduced, "The modified pyruvate decarboxylase and acetaldehyde reductase genes are transferred into the fruit DNA sequence, so that the fruit can convert pyruvate into ethanol more quickly. After the fruit is ripe, it is soaked in warm sugar water to isolate oxygen. The respiration of the fruit is enhanced, but the aerobic respiration is inhibited, so the rapid anaerobic respiration produces ethanol. When the alcohol concentration reaches an appropriate 3%, the fruit cells are still alive. Refrigerate to about 4°C and add crushed ice to suppress breathing, which can preserve the freshness of the fruit and the aroma of the wine to the greatest extent."

"Well, I didn't understand." Mint had to admit, but then said, "But you haven't answered my question—why do you trust General Schmidt more?"

"You can understand this as a kind of partiality." Yuan Yu admitted frankly, "Because I believe in my own judgment, Alumi certainly cannot represent justice, but he does things openly and aboveboard. And he respects me, he will not go against me Promise of."

"Cut." Mint poked the strawberries in the glass bottle with a straw and whispered, "Does he really respect you? He said that about people from the A clan..."

Yuan Yu was stunned for a few seconds before he realized it. He patted his forehead and said, "Oh, I'm sorry, I'm sorry, my little cutie. I forgot that you are an A-family. Alumi must also regard you as a citizen of the fleet." , otherwise he will definitely take care of it.”

What she said made Mint feel strange: "What... Yuan Yu, aren't you from the A family?"

"Me? I'm not. In the fleet, we never classify races. There is no so-called 'standard'. Everyone can look whatever they want." Yuan Yu said with a smile, "But the DA and DB genes are not Indeed an invention in the fleet."

Yuan Yushun told Mint about the history of the DA and DB genes, and it was only then that Mint realized that this was the case.

Many people say that the gender differentiation of the B group is equivalent to primitive humans, but in fact this statement is not accurate at all. There is still a big difference between the men and women of the B group and the original human beings.In fact, the purpose of inventing the DA and DB genes was not originally to create new races, but to create a more powerful army.

These two genes were originally prepared for the Defense Forces of the Fleet. The DA gene can make women taller and increase their muscle strength, bone density and hemoglobin content; while the DB gene can make men's bones lighter and stronger. , while enhancing male stamina and stress tolerance.Later, it was discovered that the DA gene would cause dysplasia of the female reproductive system, while the DB gene would cause some male secondary sexual characteristics such as Adam's apple and body hair to be indistinct.Overall, the end result of the DA and DB genes was that females and males expressing the genes had vastly improved physical performance, with physiques resembling those of otherwise human young males.

In order to enable the soldiers of the Defense Force to live like normal people, the DA and DB genes have undergone several rounds of improvement, and finally adjusted to the current version.It is worth mentioning that the modified DA gene expression will inhibit the development of the female uterus to form a smooth and elastic pouch, and at the same time inhibit the ovary's screening mechanism for follicles and the periodic change of sex hormones. The side effects are statistically It shows that it may enhance women's libido.The modified DB gene expression will inhibit the beard growth of men, and at the same time improve the adverse reaction of men's skin to androgen, which will make men's skin more delicate and healthier. s level.

At this time, the DA and DB genes are no longer as simple as strengthening the physical fitness of the soldiers of the Defense Forces, so people knocked out the parts of the DA and DB genes that enhance physical fitness, and called the remaining modified genes recessive da and db respectively. The da and db genes can greatly improve the appearance of women and men, as well as improve their quality of life, so they have been fully implemented among fleet citizens, and the DA and DB genes that improve physical fitness on this basis have become "Optional" items in the gene panel.

As for how Group A and Group B came to be, Yuan Yu is actually not very clear.The DA and DB genes in the planetary nations of human beings are indeed introduced from the fleet, but exactly how to form the A and B tribes and their inheritance methods are the secrets of those planetary nations themselves.They should have carried out more modifications to the da and db genes, especially so that males who do not express the DB gene have the ability to conceive, and can accept secondary oocytes discharged from females expressing the DA gene and fertilize and implant in vivo .Yuan Yu thinks this is a rather complicated genetic engineering work, but as a curvature drive scientist, she really doesn't know much about it.
