Yi Ting, who was at the back of the line, listened, then looked back at "Qing Xiran" wearing a mask, and asked with a suspicious look:

"They want to collect blood samples from survivors, is it really to screen for carriers of the apocalyptic virus?"

"Or else? Have your blood sample taken to check your DNA? Now that this DNA is in such a mess, what's the point of collecting it? ”

The hard "Qing Xiran" asked Yi Ting very unceremoniously, radiation causes the DNA of planetary creatures to be unstable, and this Feihua creature must have known it for a long time.

In other words, a person is one kind of DNA before the end of the world, and after the end of the world, it is possible to become another kind of DNA, and depending on the ability, the DNA sequence of the person with the ability is also different, and the DNA of the person with the primary stage and the DNA of the person with the ability at the advanced stage will also be very different.

This doesn't mean much, even if it's the same person, after living in the end times for a while, the DNA will be different depending on the level of ability.

Yi Ting glared at "Qing Xiran", turned her head over, and continued to line up without saying a word to enter the city.

She didn't know how high the identity record system of the entire era base was, and many people didn't know.

The collection of blood samples is an identity authentication project that Qing Xiran set up a few years ago in order to screen out those with hidden abilities.

But now that this project has a wider range of uses, according to the current level of technology in the era base, it is possible to roughly distinguish the type of ability that the survivor has by a drop of blood.

It's not that all abilities can be distinguished, but some rare abilities are called rare because they're uncommon, and since they're not common, there's no more information to keep track of.

At present, what can be distinguished by a drop of blood is just a very common and popular kind, such as gold, wood, water, fire, earth, strength, thunder and lightning, etc., but this is enough, at least now Qing Xiran can know what kind of abilities most of the hidden abilities will be after being stimulated with explicit abilities.

If you can't measure it, it's all rare abilities to focus on.

And the benefits of this may not be obvious to adults, but to children, it is obvious.

At present, starting from all neonatal departments under the Imperial Throne of the Times Base, the blood of newborns will be collected for testing, such a test is done once a year, and parents and effective guardians must take their children for a blood test once a year, and each child will be issued with such a blood test book similar to the pre-apocalyptic vaccine book.

Children who do not have this blood test book cannot go to kindergarten, elementary school, or education.

And will also be established by Xue Yun's maternal and child organization to follow up regularly, this family will become the focus of Xue Yun's attention, and even repeatedly persuade not to change, if the circumstances are serious, parents and guardians will be sued by the maternal and child organization managed by Xue Yun, deprived of their guardianship rights.

Xue Yun is known to everyone, she is known as the First Mother of the Last Days, as long as it involves women and children, she will take care of everything, and even nitpicking to the point of being a little hateful.

The kind of family that doesn't take her own children to the blood test, she stares at it happily. 88

Therefore, under this perfect blood test system, children under the city management system of the Times Base will carry out separate classification education for their abilities in addition to general cultural course education from an early age.

For example, a child with a fire ability will receive education on how to correctly control his fire ability from an early age, because the fire ability is an ability that can easily hurt others and harm himself.

Therefore, this kind of child has been taught to play with fire correctly, not to burn himself, nor to burn friends, teachers, parents, and urban public construction......

If you want to ask how detailed and perfect the education system of the Times Base can be, even if it is impossible to say for a few days and nights, in a system that attaches importance to education, the future of this system will definitely be thriving.

Do you want to know about these? No, they only care about their great cause of "saving the world", such a meticulous and perfect sinking work, Feihua Biotech has never understood, and does not want to understand.

However, is the purpose of collecting blood samples at the time of identity authentication just here?

No, such a drop of blood, in addition to screening out the hidden abilities and detecting the types of abilities by category, can also tell the disease control department of the Times Base whether these survivors who entered the city for the first time carry some unknown doomsday viruses in their bodies.

The apocalyptic virus is a general term, not a single virus, after all, it is the end of the world, and many animals will originally carry some viruses that humans do not know, and after entering the end times, the viruses on these animals will also mutate.

Some animals will mutate into a very terrible mutation virus, which can make the mutated apocalyptic virus attached to the human body, and some humans will be infected with this doomsday virus, which will cause great harm to the body, and the degree of damage depends on the individual's physique.

But some doomsday viruses are useless to this person, but they are useful to other people, and they are also contagious, and the key point is that this virus will spread on a large scale among human populations like the flu.

This is where one of the most important uses of blood sieves lies.

The blood screening speed of the Times Base is very fast, and once the blood sample analysis data is uploaded by the electronic testing instrument, it will be known by Qing Xiran, and she will compare several known doomsday viruses detected by the He Rifu team to give the bleeding screening alarm in a few seconds.

Those who carry the infectious doomsday virus will be denied entry to the big city, after all, most of the people in the big city are old and weak, women and children, and this aspect should be especially noted.

Therefore, for various reasons, in order to enter the era base city management system, blood samples must be collected, and any survivors who have not collected blood samples are not allowed to enter the city.

Yi Ting was very suspicious, she was probably nervous by the attitude of "Qing Xiran" in the past few days, and kept looking at the survivors in front of her who had finished collecting blood samples, and found that she had not been subjected to any additional investigation, so she was put into the city.

She also carefully filled in all her information, and let the people at the city gate collect her blood samples and fingerprints.

Because of a kind of honey confidence, Yi Ting didn't seem to think that such a remote town would pose any threat to her, except for a cautious attitude, it was no different from usual.

After she finished collecting her blood, she took Qing Xiran into Sanzhi City, and was so shocked by the orderly order in Sanzhi City that she couldn't say a word.
