Chapter 1214 - 1219: Thoughts Deep Inside
The Truth Serum was discovered a long time ago. A doctor in the United States found that after patients were anesthetized by a certain drug, they would unconsciously answer many questions accurately.
The human mental state can be divided into three levels: conscious awareness, subconsciousness, and unconsciousness. When the Truth Serum is used, the person under interrogation loses their conscious awareness. At this moment, if you ask them questions, they will reveal everything they know from their subconscious.
Of course, the Truth Serum isn’t always effective, nor is it omnipotent. For instance, it doesn’t work on mentally ill individuals because they perceive their hallucinations as a real world. Using the serum on them would yield nothing but incoherent ramblings of a madman.
Furthermore, the Truth Serum has one major drawback: it damages the user’s brain. Simply put, after using the serum, especially in large doses, the interrogated individual is likely to become an idiot, and the information extracted would be fragmented.
If the subject of interrogation is highly important or the only living clue, deciding whether to use the Truth Serum must be made with caution. A single misstep could turn the sole surviving lead into an idiot, leaving no chance for repeated questioning to cross-examine prior testimonies for truth verification.
Currently, Aaron is absent, and the decision to use the Truth Serum rests with Yang Yi.
Yang Yi pondered for a long time.
Elvin was captured voluntarily; there’s no doubt about it. But where Elvin gets the confidence to withstand interrogation by the Grey-cloaked People is completely beyond Yang Yi’s comprehension.
Receiving counter-interrogation training is perfectly normal for spies. Knowing how to handle questioning is a skill every spy should possess, though the degree of effectiveness varies by individual.
Yang Yi didn’t know where Elvin’s poise came from, nor what Elvin was capable of enduring. If Elvin revealed something beneficial to Yang Yi, it would be advantageous to Yang Yi. But what if Elvin disclosed something he wasn’t supposed to?
For example, what if Elvin framed Yang Yi’s recent betrayal as part of the Cleaners’ conspiracy? What if Elvin claimed everything had been planned from the start? Even if those claims sounded absurd, the Grey-cloaked People ought to be cautious—must be cautious—and undoubtedly prudent. Elvin’s testimony could potentially render all previous efforts futile.
