All eyes turned to her.

Tapping his knees with his fingertips, Xiao Nan said softly, "You maximize the background sound of the audio." ”

Wang Ke was slightly stunned, glanced at Jin Mo, then tapped the keyboard, dragged the cursor, and used the processing technique of decomposition and frequency reduction separation to directly get rid of the background sound.

Pressing the enter key, Wang Ke turned up the volume to the maximum, only to hear a burst of 'clang, clang, clang...... followed by a 'clang-dong'.

"Can it be louder?" Jin Mo always felt that the voice was very familiar.

Dragging the mouse, Wang Ke tried to re-grab the background sound, but he failed several times, and the effect was the same, he shook his head helplessly: "The sound is far away, and there is a sound insulation effect, its clarity and volume have reached the limit." ”

The background sound played on a loop, and everyone didn't speak again, listening quietly.

"Could it be a train?" Du Zhu hesitated.

"Not like that!" Jin Mo paced back and forth, stroking the ring, and was silent for a while, before he suddenly shouted, "Crane, yes, it's it." He thought of Xu Jiong's corpse dumping point, suddenly woke up, and said, "Jade Garden." ”

Xiao Nan saw him take people away, subconsciously looked at the alarm clock, and sighed.

Along the corridor, she walked forward unhurriedly, stopped, pushed open the door of her office, and saw a back figure next to the desk at a glance. His arrival surprised Xiao Nan a little.

She stood at the door, her eyes stayed, looking up and down, Bai Zhong was wearing a very casual dress today, a long-sleeved khaki sweatshirt with jeans, it seemed that such a match covered up the light of the domineering president, and the corners of her lips barely smiled, and said, "How long have you been here, why don't you send me a message?" ”

She sat opposite him, only to see that he was wearing a pair of sky blue half-rimmed glasses, put away the newspaper, folded it in half and put it on the table, and said with a smile: "Xiao Zhang said that you went to the criminal investigation team, I was afraid of disturbing you." ”

He saw her staring blankly at the computer screen, looking completely absent-minded, "What's the matter, the little couple quarreled again?" ”

"Nope." Xiao Nan said absentmindedly.

Bai Zhong leaned forward, put his hands on the edge of the table, and asked, "Has the person surnamed Li been found?" ”

Hearing this, Xiao Nan looked up and stopped.

Her strange appearance, Bai Zhong looked at it in her eyes, her fingers kept turning the Buddha beads on her wrist, her expression was calm, and she changed the topic at the right time: "Do you still have a job later, go out for a walk with me." ”

Xiao Nan didn't squeak, and after a while, she realized 'hmm' in hindsight. As soon as he got up, Xiao Nan's mobile phone rang, and when he picked it up, it was Jin Mo.

After connecting, she only heard a familiar and soft voice coming from the earpiece: "Li Jianjun has found it, but the person is already dead and needs to go to the doctor." ”

Xiao Nan was silent for a long time, "I, I'll let Zhang Bin go over to assist you in the investigation later." ”

The two didn't say more, cut off the phone, Xiao Nan used WeChat to notify Zhang Bin, took a deep breath, she looked at Bai Chong, and said in a muffled voice: "I, can you take me to Baisha Prison?" ”

"Okay."

Nestled in the back seat of the business car, Xiao Nan unscrewed the mineral water and drank most of the bottle in one go, for some reason, at this moment, her heart was shrouded in a trace of guilt.

White Sands Prison.

In the reception room, she saw Fang Nian, the two looked at each other, only to see Fang Nian smile indifferently, "I really didn't expect that you would come to see me." She noticed Xiao Nan's strange appearance, and frowned, "You seem to have something on your mind?" ”

"You, don't you really have any regrets?" Xiao Nan asked.

Facing Xiao Nan's brainless question, Fang Nian smiled, "It seems that the flame of your hatred has been ignited?" She glanced at Bai Chong, her shoulders shrugged slightly, her feet unnaturally together, and soon Fang Nian withdrew her gaze.

"My answer is the same as last time, and I have never regretted it again." Fang Nian rubbed the chains of the handcuffs and lowered his head, "You should understand the feeling of losing your support, but you are luckier than me, there are so many people around you who care, especially Officer Jin, I can see that he loves you very much." ”

Hearing this, Xiao Nan subconsciously stroked the ring and said softly, "I just did something wrong." She looked at Fang Nian, "Just now, I can save him, but I ......."

"Save? Are you really sure, so confident? ”

"If, if I had spoken the background sound, the guess, and the trajectory of the suspect's mental activity at the first time, he would not have died." Xiao Nan's ten fingers were staggered, and he roared: "I, I, think of them...... When I think of the tragic death of my parents, I don't want to. ”

"You're wrong." Fang Nian leaned forward, "Raise your head and look at me." ”

Staring at each other, Xiao Nan's eyes were vigilant, and he subconsciously clenched his fists, as if he was building a psychological defense line.

"Even if you tell everything, you can't save him, for a murderer who has locked on his prey, he will not give up his prey because of someone, something or some reason, especially revenge killing." Fang Nian stared at her, "Doctor Xiao, you are an expert in criminal psychology, haven't you even forgotten such a simple truth?" ”

Suddenly, Xiao Nan only felt a trace of warmth touched her fingertips, and when she came back to her senses, she saw Bai Chongchong smiling at herself.

The three of them looked at each other speechlessly.

On the way back, Xiao Nan leaned crookedly in his seat, but his brain was running fast, but he couldn't figure out why there was an alarm clock in the things he sent, timer? She quickly denied it, the picture froze, she found that the time was wrong, the moment all the lines were worn, she finally understood the intention, the psychological suggestion, the hint of time.

Taking out her mobile phone, she dialed Zhang Bin's phone and asked bluntly: "When did the victim die?" ”

After receiving the answer, Xiao Nan pursed his lips, breathed a sigh of relief, and said softly: "I'll go back now, autopsy, I'll come in person." ”

Bai Chong was dual-minded, his fingers were touching the tablet, and the corners of his mouth were slightly upturned: "It seems that you have figured it out." ”

When the two looked at each other, Xiao Nan didn't say anything, just turned his head to look out the window, and the carriage became very quiet.

Dissection room.

After changing into his surgical clothes, Xiao Nan walked to the dissection table, looked at Li Jianjun's body, and asked, "Preliminary situation?" ”

"The victim, male, aged about 42 years old, about 172 tall, according to the corpse spots and liver temperature." Zhang Bin flipped through the records and continued: "It should be between 5:30 and 7:30 this morning. ”

Xiao Nan said 'En' and nodded at Zhang Bin: "Let's start!" ”

"No injuries were found on the victim's head or shoulder." Xiao Nan leaned over to check the bruises on Li Jianjun's chest, and turned the body over again: "There are multiple bruises on his chest and back. When she looked at the few scars on her back, she frowned slightly, straightened up, her hands hung in the air, and muttered to herself, "Why? ”

With a 'bang', the wooden door was pushed open, and two figures broke into Xiao Nan's line of sight.
