Truth-telling agents have been discovered for a long time, and a doctor in the United States discovered that patients would unconsciously answer many questions accurately after being anesthetized with a certain drug.

The mental state of a person can be divided into three levels: subjective consciousness, subconscious, and unconscious.

Of course, the truth spitting agent is not useful every time, let alone a panacea, for example, the truth spitting agent is ineffective for the mentally ill, because the mentally ill person regards their hallucinations as the real world, and the use of the truth teller for the mentally ill can only get the whispers of the mentally ill.

And there is one of the biggest problems with the truth test, that is, it will destroy the brain of the user, simply put, after using the truth test, especially after using a large dose of the truth test, the person being interrogated is very likely to become an idiot, and the confession obtained is still fragmented.

If it is an extremely important interrogation object, or the only living mouth, you have to be cautious about whether to use the truth telling, because if you accidentally make the only living mouth an idiot, you will have no chance to repeat the interrogation to analyze the truth and falsehood of the confession before and after.

Now, Aaron is not here, and it is up to Yang Yi to decide whether to use the truth elixir.

Yang Yi thought about it for a long time.

There is no doubt that Erwin was caught on his own initiative, but where did Erwin get the confidence to survive the interrogation of the man in gray, Yang Yi didn't know at all.

It is very normal for spies to receive counter-interrogation training, and how to deal with interrogation is an ability that every spy should have, but the extent to which it can do varies from person to person.

Yang Yi doesn't know where Erwin's confidence is, and he doesn't know how much Erwin can do, if Erwin says something that is beneficial to Yang Yi, then it will naturally be good for Yang Yi, but what if Erwin says something that shouldn't be said?

For example, what if Erwin said that Yang Yi's apostasy was a conspiracy of the cleaners, Erwin said that everything was planned, what to do, even if these words sound incredible, but the man in gray should be cautious, and must and must be cautious, then Erwin's confession may make all the previous efforts go to waste.

Therefore, Yang Yi must make a choice.

The safest option is to let the man in gray use the truth spit on Erwin immediately, because under the effect of the truth spitting elixir, Erwin's confession will inevitably be fragmented, and he will soon become an idiot, so even if Yang Yi needs to take a certain risk, it is only a one-time risk, as long as Erwin becomes an idiot, he will be safe.

If the use of the truth elixir is not allowed, let the gray-clothed man interrogate Erwin slowly in a conservative way, it will take a long time, maybe ten days, or even a month, but Yang Yi feels that Erwin will eventually tell everything slowly, so his situation will be very disadvantaged.

Using the truth elixir, Yang Yi is safe, Erwin is less tormented, although the immediate risk is very large, but in the long run, it is advantageous, on the contrary, the current situation is safe, but in the long run, it is dangerous.

Yang Yi thought for a moment, and then he said in a deep voice to the person in front of him, "What is your truth elixir used for?" The result? ”

"The effect of the elixir is excellent, and the reason why we are sure of a quick interrogation is based on our confidence in the elixir, I don't know the ingredients of the elixir, I only know the effect of using it."

Yang Yi frowned and said, "So are the side effects big?" ”

"Big, you will definitely become an idiot, but before you become an idiot, the credibility of the confession is extremely high."

Yang Yi made a choice.

I'm sorry, Erwin, I'm really sorry.

After apologizing to Erwin in his heart and mourning for him, Yang Yi shook his head and said: "The risk is too great, in view of Erwin's special identity, we can't use the truth spitting elixir on him right away, with Erwin's identity and value, it is too risky to use the truth spitting agent for him, we can be slow, but we must be steady, so take your time in the traditional way." ”

didn't argue with Yang Yi, the person who came bowed slightly to Yang Yi and said in a low voice: "Yes, don't use the truth elixir, do you have any other instructions?" ”

"No, promise Erwin won't die, understand?"

"Understood, then I'll go to work, and I'll let you know if there's any new development, goodbye."

The door was closed, and Bonnie looked at Yang Yi with her eyes, and she meant why she didn't let the truth potion be used.

Yang Yi felt that he couldn't use the truth elixir, and his eyes told Bonnie.

There is no need to explain, Yang Yi certainly has an idea in his heart.

At this time, Yang Yi preferred to regard the power that Aaron gave him as a test.

You can't go wrong with a safe choice, and if you rush to achieve something, you may lose all your efforts, whether it's Aaron's test or not, it's at least easier to trust if it's safe.

So Yang Yi must choose a method that is easier for people to believe,

Even if he did want to use the elixir on Erwyn, it would have to be Aaron's decision.

Aaron came in the afternoon, and when he came, Bonnie was feeding Yang Yi, and after seeing Yang Yi and Bonnie's intimate behavior, he left outside and waited for Yang Yi to finish eating before coming back in.

"Did you refuse to give Elwin a truth potion?"

Aaron was smiling, Yang Yi nodded, and said, "Yes, I think the risk is too great, we have time to ask slowly, and we don't have to rush to use the truth elixir." ”

Aaron stretched out his index finger and shook it, and then said with a regretful face: "The problem is that we don't have time, and when we ask what we really need, it's too late." ”

Sighing, Aaron said in a low voice: "I understand your choice, and I should respect your decision, because I said that you are responsible for this place, but I need to discuss with you now, we will use the truth potion on Erwin as soon as possible, what do you think?" ”

Yang Yi hesitated for a moment and said, "Okay, give him the truth elixir." ”

"We can go and see, the effect of the elixir will be very fast."

Yang Yi and Aaron came to that room again, a room with surveillance, and then, Yang Yi and Aaron sat side by side in front of the screen.

On the screen, Erwin has fallen into a state of unconsciousness.

Suddenly, Erwin didn't wait for anyone to ask him, and said loudly: "Protect Yang Yi, protect the sea god, protect him to carry out the hidden plan......"

Yang Yi's face was a little ugly, of course, Aaron couldn't see it.

Aaron looked at the screen lightly and didn't say anything, and after a while, Erwin seemed to have lost all consciousness, and at this moment, someone next to him said, "Say what you think now." ”

"Kill Yang Yi! Kill Yang Yi! You must not let him live, it's too dangerous, kill Yang Yi! ”

Erwin suddenly shouted, his eyes were open, his hands couldn't move, but the muscles of his whole body were exerting force, showing that his innermost thoughts were to kill Yang Yi.
