The saliva sample was very typical. Saliva contained many things, such as salivary gland secretions, gingival crevicular fluid, mucosal exudate, buccal epithelial cells and White Blood Cells, as well as microorganisms and viruses from within the body.
The process of extracting DNA from saliva was already highly developed. Many diseases could be diagnosed through saliva. One small spit could yield data on a huge number of diseases. However, this form of medical testing was temporarily affordable only to the wealthy, and ordinary people were still unfamiliar with it.
Then there were the blood samples. The terrorists had drawn an enormous amount of blood, to the point that they had to use Artificial Blood to transfuse the mathematicians and ensure they would not die from excessive blood loss.
I did not need to say much about testing DNA through blood; everyone understood that. Blood was the only tissue that came into contact with every organ. Whether DNA or RNA, the amount of information in a single drop of blood was immense. Some Western biotech companies had once gone to Third World countries and collected genetic data under the guise of buying blood from villagers.
Finally, Eileen had her eggs extracted. This was practically an open secret: they wanted the mathematicians' genes. With multiple safeguards and multiple samples, they could ensure that they collected the vast majority of the key genes within the mathematicians' bodies.
Terrorist attacks were usually carried out to kill people, but in this terrorist attack, killing was merely a means of clearing obstacles. The true objective was to obtain the mathematicians' genes.
Third, what did they want the mathematicians' genes for?
I did not know, but everything about this matter, inside and out, exuded a sense of horror. Mathematicians were the smartest group of people in the world,
