As a multi-millionaire, Ren Xuefeng's mobile phone is an important communication tool for contacting customers, which means that he cannot change his number frequently. Therefore, his two mobile phone numbers are regular mobile phone cards obtained through ID cards, which greatly facilitates Zhong Han and Gu Xiaofan's next move. Without much effort, they obtained the call records of these two numbers in the past year from the communication company.
Ren Xuefeng had a lot of call records. Fortunately, Gu Xiaofan was also famous for his patience. He started screening without even frowning. Screening call records required carefulness and patience. Paying attention to every phone number that was in close contact with Ren Xuefeng and following the clues to find out the owner's information was only part of it. Another important thing was to pay attention to 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 rest from time to time to avoid losing his attention due to fatigue and missing some details. However, Gu Xiaofan kept watching without any hurry or slowness, and showed no signs of being bored because of boredom.It was time to get off work, and Ren Xuefeng's dense call records were still halfway through the screening. 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 records before, and he didn't notice anyone approaching him. He was suddenly knocked on the table by Zhong Han, and heard his voice, and was startled. He suddenly raised his head and looked at Zhong Han. He was stunned for a second before he breathed a sigh of relief, reached out and 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 yet, it's meaningless to start working day and night now.""Oh, then I'll pack up now." Gu Xiaofan has always been easy to talk to, not to mention that what Zhong Han said is not unreasonable, so she simply tidied up her desk and stuffed the stack of Ren Xuefeng's call records into her purse, "Okay "Let's go home!""Are you going to take those things home to finish them?" Zhong Han looked at her stuffing the call records into her bag and was a little surprised. "To be honest, you were slacking off at work yesterday, but today you suddenly became a workaholic who works overtime and day and night. I am a little uncomfortable. Is it because I have known you for too short a time that you still have many personality aspects that I have not understood?"Gu Xiaofan thought of the fact that he was slacking off the day before and was caught by Zhong Han. He couldn't help blushing and waved his hand quickly: "I didn't deliberately do that because you caught me slacking off once. I want to pretend to be dedicated in front of you. I am not as smart as others and I forget too much. I have only done half of it today. If I don't strike while the iron is hot and finish the rest, I will have no idea tomorrow and have to start all over again. That will be more troublesome. So I might as well take it home and continue to work on it after dinner. At least I can sort out the phone number first, and then confirm the owner's information when I arrive at the office tomorrow. ""The early bird catches the worm, and your spirit is commendable. Take your things and go quickly. I drove here today. I will carry forward the spirit of mutual help and friendship and send you back." Zhong Han took out the car keys from his pocket and shook them in front of Gu Xiaofan.Gu Xiaofan was a little surprised: "Can you do it?"Zhong Han raised his eyebrows: "Your words are simply an extreme provocation to men's dignity.""Oh, I mean whether you can recognize the road when driving. Don't think in a crooked way!" Seeing Zhong Han's reaction, Gu Xiaofan's face immediately turned red, and he hurriedly clarified for himself.Zhong Han spread his hands innocently: "I'm talking about the problem of knowing the way. Didn't I tell you that you should never question a man's ability to know the way and sense of direction in person? This is an important part of a man's self-esteem. What do you think I was thinking?""I..." Gu Xiaofan felt that he was definitely fooled by Zhong Han, so he just smiled and pretended to be confused, "I didn't think anything. Today I really have to take your car to see if you are bragging or you are really good at it!"The two went downstairs together. After getting in the car, Gu Xiaofan asked while buckling his seat belt, "You didn't know the way yesterday, but you took two buses. Today, all of a sudden, you know the way?""How is that possible?" Zhong Han started the car and drove out of the hospital gate. "After I went home last night, I had nothing to do and looked at the urban map of City A several times. It's hard to say about the suburbs, but at least I think there shouldn't be much problem with the city center.""Really? You can remember the way just by looking at the map a few times?" Gu Xiaofan felt a little unbelievable."I still say the same thing--""Never question a man's ability to recognize roads and sense of direction in person!" Gu Xiaofan nodded, "I remember, let's wait and see. Anyway, I got off work early today and I'm not particularly hungry. At most, I can accompany you to get lost and walk around a few more times, just take it as a ride."The final facts proved that Zhong Han's bragging was indeed not nonsense. Gu Xiaofan didn't spend any time on such things as a ride. Zhong Han sent her home smoothly without taking any detours. His familiarity with the road was like that of a native of City A. This made Gu Xiaofan, a road idiot, have to admit that as a human being, the good memory and sense of direction he was born with were really unique.And Zhong Han's unique qualifications refreshed Gu Xiaofan's cognition early the next morning."No way? I took the rest of my call records home last night, and I have been sorting them out since I finished dinner, and I have been sorting them out until I went to bed at around 10 pm. How come you said you had finished them when you came this morning?" Gu Xiaofan thought that she had taken the work home to finish it, and she might need to wait for Zhong Han to catch up with her progress today. Unexpectedly, when she arrived at the office in the morning and asked, Zhong Han told her that his part had already been counted."One possibility is that I secretly took the work home without telling you last night, and the other possibility is that when I called you off work yesterday, I had actually finished it. Which one do you think is more regrettable? You can choose it." Zhong Han handed the one he sorted out to Gu Xiaofan, and took her part from her.Gu Xiaofan knew that no matter what she did, she would never choose the first possibility. Obviously, Zhong Han had finished his part of the work yesterday, so he was busy going off work."You are such a mean person," Gu Xiaofan looked at Zhong Han with a little dissatisfaction, "Since you have finished it early, why don't you help me share some of the work.""Even if I have finished my own work early, why should I help you share your work?" Zhong Han asked Gu Xiaofan leisurely with his arms folded."The more capable you are, the more work you should do. There is also the spirit of solidarity and mutual assistance among colleagues!""What you said makes sense, but did you ask me for help from beginning to end yesterday?" Zhong Han listened to the reasons given by Gu Xiaofan, nodded, and happily accepted it.Gu Xiaofan was stunned. It seems that he did not ask Zhong Han, but just wishful thinking that Zhong Han did not finish his half of the work task."Then..." Gu Xiaofan hurriedly forced a smile, "Comrade Zhong Han, since you are so capable and efficient, why don't you help verify my copy of the owner's information as well?"Zhong Han gave her a half-hearted smile: "Sorry, no.""You just said clearly that you didn't help me yesterday because I didn't ask you for help. Now I'm asking for help." Gu Xiaofan didn't expect him to refuse so readily."I said you didn't ask me for help yesterday, but I didn't say I would definitely agree if you asked me. If you ask for help, you have a chance to get help, but I also have the right to refuse." Zhong Han looked helpless.Gu Xiaofan glared at Zhong Han without any killing power, turned around and left: "Forget it, if you don't help me, I'll do it myself.""Before verifying the owner's information, don't forget to check the copy I made first." Zhong Han stopped Gu Xiaofan and pointed to the stack of call records in her hand and the important information he summarized the day before.Gu Xiaofan slapped his forehead, returned to his seat, sat down and checked carefully.After they quickly reviewed each other's work results and confirmed that there was nothing missing, they began to verify the information of the owners of the phone numbers that were highlighted above and had frequent contact with Ren Xuefeng.Some of the numbers were owned by several suppliers and business people in the company who had close contact with Ren Xuefeng. There was nothing special about them, so they were quickly excluded by Zhong Han and Gu Xiaofan. Soon, one of the numbers caught their attention.Although the calls between this number and Ren Xuefeng were not the most frequent, they were very regular. In the call records they could grasp, this number had always been in contact with Ren Xuefeng, and basically most of the time, it was Ren Xuefeng who took the initiative to contact the other party. The call time was not long each time, but the frequency was not low. It was not until half a year before Ren Xuefeng was killed that the contact with that number was slightly reduced. After Ren Xuefeng disappeared, this number never appeared in his call records again.What's more interesting is that the owner's information of this number shows that the other party is a woman, 26 years old this year, the same age as Ren Yumeng. Zhong Han and Gu Xiaofan roughly learned about the other party's information and found that this young woman only has a junior high school education and no fixed job, but has two properties and a car worth hundreds of thousands of yuan.Zhong Han and Gu Xiaofan decided to meet this woman, preferably in an unobtrusive way.
