She frowned, and the phone stopped vibrating and the cacophony was gone.

Su Jin looked at his phone suspiciously, and then Yuan Ke dialed another phone call and came in, and like Fang Cai, a sharp and piercing voice appeared again.

With a glance and a drop on his watch, Su Jin tried to take the phone away, but after the phone was half a meter away, the harsh voice was gone.

She zoomed in again, and as soon as the phone approached her watch, the ringing reappeared, and the closer she got, the sharper it became.

With a slight sinking heart, she stared at her watch, vaguely aware of something.

"Yuan Ke......" She answered the phone, her eyes fixed on her watch.

"I'm at your door, are you up?" Yuan Ke's voice sounded very happy, and he returned to his former liveliness and cheerfulness.

Su Jin looked at the time, it was already six o'clock in the evening, and she had slept for so long.

"Hmm." She answered and hung up.

Su Jin held the phone and stared at the watch, she put it to her ear and shook it, frowning and pondering.

Half a minute later, she clicked on her phone's screen.

Su Jin wanted to verify her guess, and was originally going to call Yuan Ke, but clicked on Shan Chenxun's mobile phone number.

The moment the phone was dialed, she heard a piercing and sharp sound, she took the phone away, the sound disappeared, approached, and the voice appeared again.

She was finally sure that there was something wrong with the watch!

The man didn't answer the phone, and the microphone came: "The phone you dialed is not answered for the time being, please dial again later......"

Su Geun hung up the phone, put the buttons in the drawer, she changed her clothes, and poured the watch into her pocket.

She went out to open the door, and Yuan Ke was wearing a white dress and white pants, standing at the door refreshed.

"Forensic doctor Su, long time no see! I miss you so much......" She smiled sweetly, swept away the mourning of many days ago, jumped in front of her, and hugged her.

Su Jin pushed her away without a trace, and said expressionlessly: "What if a tracker is installed in a thing, what happens if you get close to the communication device?" ”

"Huh?" Yuan Ke was a little confused, confused by her sudden question, "What...... What the? ”

Su Jin repeated the question again, Yuan Ke touched his head, and then he reacted, "Oh, it will make a sound!" What's wrong? Who put a tracker on you? ”

Su Jin was silent, and walked back to the living room with her eyebrows twisted.

"In addition to trackers, pinhole cameras also have sounds when they are close to communication devices, and we usually use our mobile phones to ......make phone calls when we check hidden cameras in public places," Yuan explained, "but not all of them work." ”

"Xiao Yuan, please do ...... excuse me" Su Jin took out her watch, turned to her and said, "Find someone to help me test this watch." ”

"Whose watch?" Yuan Ke just arrived in the region, and he didn't know that this was Shan Chenxun's watch, "Men's watch? Whose? ”

She was curious.

"Don't ask, test for me, remember, don't let anyone else know."

"Okay, leave it to me!" Yuan Ke was naturally willing to help, and she put away her watch.

Su Jin had dinner, and then went back to the police station with Yuan Ke.

When I arrived at the police station, I learned that Shan Chenxun still didn't come to work during the day today.

"What's going on with the boss?" Yuan Ke also called him yesterday, when Shan Chenxun agreed to her reinstatement, and didn't say much, as if something was wrong.

She was too embarrassed to disturb him, so she hung up.

He Bin continued to call Shan Chenxun, and the phone was connected, but no one answered.

"I've been calling for twenty or thirty ......" The boss doesn't come to work or answer the phone, and the team members are not at ease, so they don't get off work.
