Reading the interrogatee's identity information in front of them is a common interrogation technique aimed at putting pressure on the individual.
If the person conducting the interrogation is a member of an illegal organization, the pressure effect is doubled, implying that we have control over your social relationships; if you do not comply with us, we will target your loved ones next.
The problem was that the senior researcher, holding documents in his hand, did not actually have my personal information; in fact, the person described in the documents likely did not exist in this world. Not only was there no pressure effect, but I also had to control my facial muscles to keep from laughing.
Perhaps seeing my demeanor "waver," the senior researcher's expression lightened slightly as he feigned kindness, saying, "You can rest assured. As long as you cooperate with our research, your parents and friends will be safe."
