Not long ago, a large number of aliens infiltrated the earth, which attracted the attention of the authorities.

Later, certain measures were taken to eliminate these aliens in a timely manner. However, the work of clearing out aliens did not stop, but moved from the front stage to behind the scenes.

The blond man and his companions are members of this organization, which has a name called DK Association.

The foundation of the DK Society's operations is big data. With the advancement of technology and the widespread adoption of computer technology, coupled with the global surveillance system, population census has become a reality.

And Aya is a dangerous person who was screened out under such circumstances.

The people screened out through big data are highly suspected of having alien ancestry. However, computers cannot replace humans after all, so at the critical moment, the association still sent two prosecutors to verify Aya's identity.

It is not easy to verify Aya's identity. First of all, she lives in a wealthy family, which means it is extremely difficult for ordinary people to contact her. Although Aya does whatever she wants, it is not so easy for ordinary people to see her.

The two prosecutors went to great lengths and finally, with the help of the association, disguised themselves as doing business and obtained an invitation to the banquet.

Now the two prosecutors stood in the garden, observing Aya's behavior closely and found that she was no different from a human being.

"We can only take her body samples for further testing!" said the blond prosecutor resolutely.

The so-called samples are hair and skin dandruff.

This requires obtaining Aya's hair or the clothes she has worn.

This was not the first time that these two prosecutors had cooperated in carrying out such a mission. After they had discussed it, the blond man walked over with a smile and started a conversation with Chu Yongkang.

It just so happened that the company they used as a cover was also researching artificial intelligence, so Chu Yongkang gave him face and started chatting with him very warmly.

The blond man chatted with Chu Yongkang for a few words, and seeing that the atmosphere was good, he shook his hand and spilled the wine on Aya.

"Oh, sorry," the blond man looked bewildered.

He did it so skillfully and naturally that everyone just thought he had made a mistake. No one could have imagined that he had any ulterior motives.

Aya has been living with everyone for some time and is very familiar with social interactions between humans. She immediately smiled and said it was okay, and told Chu Yongkang that she was going to change her clothes.

Because this was a banquet held at the Chu family, Aya went to her room, changed out of her wet dress, and put on a new one.

Aya didn't deal with the clothes she had taken off. She just put them in the dressing room temporarily and then left to go back to the party.

As soon as Aya left, another member of the association flashed in from behind the door. He recognized the clothes at a glance, folded them carefully, wrapped them in transparent plastic film and hid them on his body.

Summer clothes are made of light and thin materials, and these two people are specialized in this job, so everything was done seamlessly.

By the end of the banquet, the Chu family had not noticed anything unusual, so the two association members successfully stole the dress.

So Aya's body specimen was inadvertently obtained by the association.

The association got the sample and did not alert the Chu family. Instead, they began testing it overnight. Since Aya's appearance was exactly the same as that of an Earthling, the testing of her sample could only be done at the genetic level.
