Behind the Murder Volume I

Chapter 18: The Secret of Call Records

As a multi-millionaire businessman, Ren Xuefeng's mobile phone is an important tool for contacting clients. This means that he cannot change his number frequently. Therefore, both of his mobile phone numbers are regular mobile phone cards obtained through his ID card. This greatly facilitates Zhong Han and Gu Xiaofan's next move. Without much effort, they obtained the call records of these two numbers for the past year from the telecommunications company.

Ren Xuefeng had a lot of call records, but fortunately Gu Xiaofan was also famous for his patience. He started screening them immediately without even frowning. Screening call records required carefulness and patience. Paying attention to every phone number that had close contact with Ren Xuefeng and tracing back to find out the owner's information was only part of it. Another very important thing was to pay attention to details such as the number of calls, duration, and most frequent time periods of those frequently contacted phones. Therefore, it was even more tiring than surveillance video. Zhong Han had to stop and take a break from time to time to prevent himself from losing concentration due to fatigue and missing some details. However, Gu Xiaofan kept watching without any hurry or slowness, and showed no sign of being bored.

It was time to get off work, and half of Ren Xuefeng's dense call records had not been screened yet. Zhong Han stretched his stiff upper limbs, gently rubbed his tired eyes with the back of his hand, stood up and walked to Gu Xiaofan's desk, knocking on the table with his knuckles: "get out of class is over, go home after school!"

Gu Xiaofan's attention was focused on the call record before, and he didn't notice anyone approaching him. He was startled by Zhong Han knocking on the table and hearing his voice. He suddenly raised his head and looked at Zhong Han. He was stunned for a second before he breathed a sigh of relief. He patted his chest and said, "Oh, you scared me! It's already this late? But... we haven't finished this yet."

"Don't make unnecessary sacrifices, don't work unnecessary overtime, this is a great respect for life and health." Zhong Han shook his head at Gu Xiaofan and pointed at his watch. "Ren Xuefeng's case has just begun. It hasn't reached the real stage of investigation. It's meaningless to start working day and night now."

"Oh, I'll pack my things now." Gu Xiaofan was always easy to talk to, and what Zhong Han said made sense, so she simply tidied up her desk and stuffed the stack of Ren Xuefeng's call records into her purse. "Okay, let's get off work!"

"Are you going to take those things home and finish them?" Zhong Han was a little surprised as he watched her stuff the call records into her bag and prepare to take them away. "To be honest, you were slacking off at work yesterday, but today you suddenly become a workaholic who works overtime and day and night. I am a little uncomfortable with this. Is it because I have known you for too short a time? Do you have many aspects of your personality that I don't know yet?"

Gu Xiaofan thought of the time when he was distracted and was caught by Zhong Han the day before. He couldn't help blushing a little and waved his hands quickly, "It's not because you caught me distracted once that I pretend to be dedicated in front of you. I'm not as smart as others and I forget things easily. I only got half of it done today. If I don't strike while the iron is hot and finish the rest, I'll have no clue by tomorrow and have to start all over again, which is even more troublesome. So I might as well take it home and continue working on it after dinner. At least I can sort out the phone number first and confirm the owner's information when I get to work tomorrow."

"The early bird catches the worm. That's commendable. Take your things and leave quickly. I drove here today. Let's show you the spirit of mutual help and friendship and send you back." Zhong Han took out the car keys from his pocket and waved them in front of Gu Xiaofan.
