My big knife is already hungry and thirsty gl

"When she was asked about her name, age, and where she was that night, the expression on her face was very flat, because these are the most basic questions, and she didn't need to think much at all. If the reaction time for an answer exceeds one second, it proves that she is lying. Obviously she is telling the truth." Jing Zhi's voice paused for three seconds, "But, look carefully at her expression when she asked the last question."

Shen Congyuan took the phone slightly away from his ear, and asked a policeman to adjust the progress of the interrogation video that day to the time for asking the last question.

"Keep your voice down." Jing Zhi reminded on the phone.

Shen Congyuan was stunned for a moment and then understood that Jing Zhi asked him to focus on observing the expression.

"Slow down the playback speed and pay close attention to the micro-expressions on her face when she answers the questions."

"The pupils are dilated." Shen Congyuan tightened his hands while holding the table to watch the video, and his body leaned forward sharply as if he was about to get into the screen. Shut up."

"Yes." Jing Zhi put his hands in his pockets and stood upright, "In micro-expression studies, these are typical manifestations of anger."

"Angry?" Shen Congyuan strode out of the monitoring room, "Does this mean she is lying?"

"Not necessarily." Jing Zhi touched his nose, "However, even if she didn't lie, it doesn't mean she doesn't have that kind of thinking."

"What do you mean?"

"Even if she hadn't drugged the couple, there was a moment in her head that did."

"Don't hang up first." Shen Congyuan turned his head and called someone, "Let Gao Yue immediately bring Wei Yun to the interrogation room at the speed of a [-]-meter sprint, hurry up!"

Shen Congyuan turned to the left, walked in the depths, and finally entered the interrogation room and sat down.

"I said, Shen Congyuan, why are you still so impatient!"

"To shut up."

"..." Jing Zhi remained silent.

Five minutes later, Gao Yue walked in handcuffed Wei Yun.

Shen Congyuan didn't talk too much nonsense, and cut straight to the point: "Did you drug the couple on the night of July 14th?"

"No."

Shen Congyuan patted the table: "Since there is no you, why are you angry?"

"No." Shen Congyuan didn't make any movement this time, his eyes moved slightly, and there was a clear expression on his face.She had those expressions just now again, dilated pupils, flaring nostrils, pursed lips.

She is still very angry but has not vented it, which means that she has endured it for a long time and can control her anger and will not express it easily, but she is an ordinary person after all, as long as she has emotions, she will have corresponding micro-expressions, and micro-expressions Expressions cannot be hidden.

Shen Congyuan leaned back in his chair, staring closely at Wei Yun's eyes: "Grandma, just talk about it if you have something to say, you can't solve any problem by holding it in your heart. People are dead, whether you did it or not, you Tell me the truth so I can save you."

Seeing some changes in the expression on Wei Yun's face, Shen Congyuan asked again while the iron was hot: "Grandma, did you drug them on the night of July No. 14?"

Wei Yun's rough fingers were twisted together, and because of his age, even if his hands were held together, they couldn't help shaking, "I didn't give them any medicine."

Her lips were tightly closed, and the movement of her nostrils turned outward was so obvious this time that she couldn't help it.

Sure enough, within three seconds she said without a word: "But I think so."

"Send her back." Gao Yue looked at the back of Shen Congyuan who got up and walked out of the interrogation room. He was completely confused. What happened to the captain? After asking a question, he left without saying anything?Fortunately, the one who ran just now was called a desperate, tired heart.

"You heard it all." Shen Congyuan didn't stop, the soles of his leather shoes thumped on the ground, "You're all right, you guessed well."

"What is guessing!" Jing Zhi was praised by Shen Congyuan for the first time, and his mood was so high that he could go to heaven, "That's called science, science. Who am I, Jing Zhi, an expert in micro-expression research, one of the top professionals in China. Hmph, feel me Is it amazing?"

"Shut up." Shen Congyuan yelled in a low voice, "I'll send you a video later, take a look and call me immediately if you find any problems."

"I'm exhausted as a cow and a horse, don't you give me any reward?"

Shen Congyuan didn't answer and suddenly asked a question: "Have you ever had sex with your boyfriend?"

"I... did it." Jing Zhi blushed, Shen Congyuan must be sick, why did he suddenly ask such a question, didn't he always resist this kind of thing.

"First, you hesitated for three seconds before answering; second, your voice was stuttering. Conclusion - you are lying."

"..." Jing Zhi was so angry that he scratched his heart and lungs. Damn it, Shen Congyuan is simply not a human being. He learned his skills and turned him into an army every minute.No, what's the matter if you haven't done it before, he knows the theory, he knows the [-] formulas, it's better than someone who doesn't know anything and only knows how to deal with cases.

"I know your secret, I won't tell it." At this moment, Shen Congyuan's magnetic voice made Jing Zhi feel like hitting someone, "Secrecy is worth reward, right?"

The sound of disconnection rang in Jing Zhi's ears for more than a minute before he realized it.After this reaction, he was so angry that his liver trembled.Shen Congyuan really...he really wants to use one hundred and eight moves to fuck him.

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊

"She's not lying." Jing Zhi was also surprised, so he turned up his voice so that Shen Congyuan on the other side could hear him clearly.

"Did you put rat poison in the meals of the master and his wife on the night of July 14th, causing them to die?"

"Yes."

After pausing the recording, the sound immediately disappeared.

"When she answered 'yes', the reaction time did not exceed one second, which means that she was very clear-headed and very sure of her answer." Jing Zhi rubbed his chin in a state of thinking, as if he was asking himself or thinking Ask Shen Congyuan on the other side of the phone, "The same person has the same question, but they have different answers at different times, but none of them are lying. What does this mean?"

After being silent for a full 5 minutes, Jing Zhi suddenly got up: "I'll hang up first, and I'll call you when I get the results later."

There was an excited expression of fighting spirit on his face, and his eyes were shining brightly.He finally hit a problem that he couldn't solve in 5 minutes, kind of funny.

The moment he put down the mouse, he laughed easily and clapped his palms a few times. ok, the problem is solved.

Shen Congyuan, who was always waiting for the phone, picked up the phone after it rang: "How is it?"

Jing Zhi said with a smile, in a relaxed tone: "Dissociative amnesia."
