Chapter 2193

"Well, after the murderer entered the interrogation room, he refused to say a word!

Our interrogation in China is humanized and is not allowed to be executed. We may need to borrow your special interrogation method. "

"OK! I'll try!"

Huo Zheng immediately entered the working state, and Yang Ruoyu suddenly interrupted.

"Dealing with such people requires psychological means. I can help!"

"But you..."

The captain obviously hesitated.

"You are neither a policeman nor a member of the national security system. You are an ordinary citizen and can't participate in our interrogation!"

"But you have made no progress now. Why don't you consider accepting my help?"

Yang Ruoyu frowned and looked puzzled.

"Let her try."

Huo Zheng suddenly opened his mouth and looked serious.

"I believe she can bring a breakthrough to our trial!"

"But her identity..."

"I can handle this!"

Huo Zheng took out his mobile phone and called aunt Hong,

Explained the whole story,

"Then let Yang Ruoyu assist you in your interrogation as an interrogation expert! I'll arrange the identity matters.

You go in now and leave the rest to me! "

"Thank you, aunt Hong!"

Huo Zheng hung up and looked at the police captain.

"Is it OK this time?"

"All right. Let's go!"

"Wait!"

Yang Ruoyu suddenly opened his mouth,

"I have one more thing to prepare."

Ten minutes later,

The door of the interrogation room opened again,

Yang Ruoyu came in with an instrument that he didn't know what it was,

As soon as she came in, she handed the instrument to the police officer,

"Connect the two pieces of copper with wires and stick them behind his ears and chest."

The officer in charge of the guard did it immediately,

Bell looked warily at the two copper pieces and opened his mouth coldly.

"Torture is not allowed in China's interrogation!"

"Oh, you finally spoke."

Yang Ruoyu raised his eyebrows and smiled and sat down in a chair,

"This is not torture to extort a confession, and the two copper pieces are not to shock you. Don't worry."

With that, Yang Ruoyu stopped looking at Bell, but focused on the computer in front of him, as if analyzing some data.

"Now your heart rate is very stable. It seems that the accuracy of this lie detector is good."

Lie detector?

Bell eyebrows a pick, Yang Ruoyu immediately surprised.

"Are you guilty? Your heart rate fluctuates obviously!"

Bell's face suddenly became ugly,

What lie detector is useless as long as he doesn't say a word.

But Yang Ruoyu seemed to see through him and then opened his mouth.

"It's no use not talking. Next we'll ask you some right and wrong questions,

This lie detector will not only measure your heart rate, but also your brain waves. As long as you respond to an answer,

We'll know right away. We don't even need you to talk! "

"You!"

Bell stared at Yang Ruoyu fiercely. He was going to kill her!

"What are you looking at!"

Huo Zheng keenly caught the murderous spirit of the murderer and immediately stretched out his hand to block Yang Ruoyu.

Seeing Huo Zheng's reaction, Yang Ruoyu was slightly stunned.

She really doesn't understand this person.

"He can't hurt me now. Let's start the trial!"

Yang Ruoyu opened the book,

Huo Zheng opened his mouth faintly.

"Why did you kill Vincent? Is it because... Is he your enemy?"

As soon as Huo Zheng's voice fell, the lie detector immediately fluctuated violently! Even raised an alarm!
