Hearing Lin Wan'er's question, the old man pursed his lips and sighed: "Miss, there is actually a very troublesome underlying logic behind this matter."

Lin Wan'er said: "You said."

The old man said: "Whether it is the first or the second, the number of people hidden is actually not small. Some special talents, military experts, intelligence personnel, and special service personnel, are all encrypted, and there are thousands or tens of thousands of people in the country."

Speaking of this, the old man changed his mind and said, "But, the trouble is that although these two hidden people have a database, most of the people who can contact this database do not have the highest authority for this database."

"That is to say, if I had hidden the information of two people by these two methods back then, even if I had the authority to this database, I could only access the information of these two people. The information of others was not authorized. Not only did I have no right to access, I didn't even know how many people there were;"

"On the other hand, even if you have the relevant permissions of this database, you cannot find the person I am hiding in this database. We two are insulated from each other;"

"Also, there are multiple branches here, each with different levels and authority. For example, the intelligence department, its highest person in charge, has the right to access all hidden information from the intelligence department, but does not have the right to access the situation of other departments."

Lin Wan'er thought for a while and asked, "Someone must have the permission to access the entire database, right?"

The old man smiled awkwardly: "Miss, there are very few people with authority, and they can count it with one hand. Moreover, these people will never be able to leak information to anyone without authority, so I can't go through this path at the moment."

"I understand." Lin Wan'er nodded, knowing that it is impossible to start with the database access permissions.

So, she pondered for a long time, suddenly remembered something and asked, "By the way, if a person has been hidden from birth, can he still find out the information he had not been hidden before?"

The old man replied: "If all information is hidden in the first way, and this person seems to have never appeared in this world, the information about his birth will be erased;"

"If it is the second type, it depends on how the person hiding his information operates. Some people may erase them all for certain purposes; but if some people want to create the illusion that the person is missing, they will not erase the previous information, because this information must be made public and respond to inquiries from those who are interested."

"For example, when a person graduated from university at the age of 22, for some reason, needs to evaporate from others. Then his archive information before he was 22 years old will not be erased. He will only add a missing person or a dead tag to his file. This information will not be encrypted. Even if it is just an ordinary police officer with the lowest authority, he can easily find the archive information before he disappears in the population system."

Lin Wan'er's eyes lit up and she blurted out, "Does the messages you just gave me include Ye Chen who has disappeared and died?"

The old man replied: "Including missing, but not confirmed death."

Lin Wan'er suddenly realized that she had indeed seen a lot of information about children just now.

However, when I saw the photos of the children, I skipped them directly and did not look at the specific information of these children carefully.

However, this will ignore a situation, that is, if the child's photo is not the child's current actual situation, but the child disappeared when he was young, and his file information is still stuck when he was young and has not been updated. In this situation, I will ignore it just now.

So she quickly said to the old man: "I will re-read the information of the missing person first. If it can't be found, please help me retrieve the information of the dead person."

The old man nodded: "No problem!"

He looked at the computer again, returned the information to the first person, and then began screening one by one.

Soon, a black and white photo appeared in front of her, causing her pupils to shrink suddenly.

The boy in this black and white photo looks only six or seven years old. The boy looks handsome, and his facial features and charm make Lin Wan'er feel a little familiar.

Then, she looked at the boy's message and muttered: "Ye Chen, from Yanjing, the son of Ye Changying and An Chengqi..."

"This Ye Chen studied at Yanjing Second Experimental Primary School twenty years ago. He transferred to Jinling First Primary School twenty years ago, and then disappeared, and the archive information has never been updated..."

When the old man heard her mutter, he couldn't help but say, "Ye Changying, An Chengqi? This couple was a powerful man in Yanjing more than 20 years ago!"

Lin Wan'er asked him: "Have you heard of it?"

"It's not just heard of it." The old man said seriously: "I have some friendship with the Ye family. The old house of the Ye family is not far from me. You can get there in half an hour. The Ye family is the top three in China. Ye Changying was the most outstanding backer of the Ye family back then. His wife An Chengqi is an investor in almost the entire Silicon Valley. By the way, An Chengqi behind An Chengqi ranks second in the United States."

"So that's it!" Lin Wan'er nodded and sighed: "No wonder the name An Chengqi is so familiar. I seem to have read a biography of her."

As he said that, Lin Wan'er looked at Ye Chen's black and white free-title photo taken before entering the first grade of elementary school, and said seriously: "I see this child, it's a bit similar to the Ye Chen I'm looking for. Combined with the name Ye Chen, I guess it's probably him."
