Ding!
The long-unheard, familiar buzzing sound made Yang Sen and Old Bai, who had just entered the room, pause slightly.
Seeing Lu Chuan in front of the computer, Yang Sen asked in surprise, "Lu, are you comparing fingerprints?"
The fingerprint matching system only makes this special buzzing sound when a complete match is found and successful.
Old Bai casually took a cigarette from the pack of Zhonghua on the table, handed one to Yang Sen, lit one for himself, and walked over to hand one to Lu Chuan: "Didn't you and Old Liu go out for visits this morning?"
The four of them went out together, it didn't seem right.
Taking the cigarette, Lu Chuan held it with both hands, put it in his mouth, and leaned towards Old Bai's lighter: "We did, came back early."
"Since there's nothing going on, I handled the fingerprint matches accumulated this week."
This week?
Yang Sen and Old Bai exchanged a glance, knowing full well about this week's fingerprint matches.
