Even the old guard felt that Zhang Guowen was wrong, which meant that there was a big problem here.

For Gu Chen, now it is necessary to understand the correct relationship between Xu Yun and Zhang Guowen.

What is right? Of course, it's not as simple as it seems.

However, from the current point of view, Gu Chen has a high probability of solving the puzzle.

Although it is said that Zhang Guowen used to be Xu Yun's master, he almost taught her the introduction of work by hand.

But why Xu Yun was transferred to another branch, this situation seems to need to be investigated in depth.

The most important thing is that Zhang Guowen evades surveillance and stays under the single apartment rented by Xu Yun in the middle of the night, which is very revealing.

And just last night, Xu Yun was also bombarded with phone calls, but she didn't show too much nervousness, so that everyone thought it was her family's concern.

A veteran bank employee, a front desk intern.

The relationship between the two people beyond ordinary people does make things confusing.

If there is no estrangement between the two, then Xu Yun does not need to jump out of the original unit, she can reflect her value in the work unit at any time under the care of the master.

But now that she's in a new environment, all the conditions have changed imperceptibly.

Not to mention anything else, the dirty work must have fallen on Xu Yun's head.

Even Wang Shaofei, who has just been working for a short time, is an old employee in front of Xu Yun at this moment.

In principle, chores can be handed over to Xu Yun, and he doesn't need to do everything himself.

In addition, in terms of performance appraisal, there is no need for Wang Shaofei to worry too much about this budding newcomer.

Wang Shaofei only needs to do his job well, that is, to win Xu Yun, who is more adorable than himself.

This kind of job change, in everyone's opinion, can't give Xu Yun too many benefits.

Gu Chen took out his mobile phone and couldn't help but say: "It's better to call Xu Yun and ask her to come over, otherwise it will be difficult to explain the clues in the room, after all, the last place where Zhang Guowen disappeared was this bachelor apartment." ”

"I'll do it. Officer Wang directly took out his mobile phone and dialed his cousin Wang Shaofei's phone.

After 30 minutes.

A taxi stopped on the side of the road, Xu Yun hurriedly got out of the car, panting and walking in front of everyone.

"I'm sorry, I'm late. ”

"It's okay, let's go upstairs. ”

"Oh, it's not like waiting. ”

Xu Yun felt a little panicked.

After all, the conversation on the phone is difficult to explain clearly for a while.

She tried to calm down, and then she said, "You want to go to where I live?"

"That's right. Gu Chen called up the video of the surveillance screen, lit it up directly in front of Xu Yun and said, "Last night, did Zhang Guowen come to you?"

"Uh......"

"What is he doing here?"

"I ......"

"Don't tell me you don't know. ”

"Well, he's been here for me, but ......"

"But what?"

"But then he left, and I left after that. ”

Listening to Xu Yun's panicked remarks, Gu Chen just smiled lightly.

Something to be expected.

After all, Xu Yun herself would not admit it so easily.

She was able to deceive everyone yesterday, and she can still do it today.

Including her on the phone, as she described Zhang Guowen by herself, no one knows whether it is true or not.

Originally, she could have informed Gu Chen of the situation on the phone, the fact that Zhang Guowen had come to her last night.

However, she didn't say anything, not a word.

And now, according to the clues, Gu Chen followed the vine and directly found the evidence that Zhang Guowen came to find Xu Yun here last night, and Xu Yun suddenly panicked again.

"It's all here, aren't you going to invite us to go up and sit down?" Officer Wang said, still breaking the embarrassment of the scene.

Xu Yun squeezed out a wry smile, and said indifferently: "That's okay, I'll take you up." ”

came to Xu Yun's residence, and everyone followed Xu Yun into the house together.

The house of the single apartment, indeed as the doorman said, is suitable for one or two people to live here, the more people, the more crowded.

Although there are two floors of partitions, the space is extremely small.

Gu Chen walked at the door and took the initiative to put on shoe covers for himself.

When others saw this, they followed suit.

Xu Yun didn't mind: "It's okay, it's okay to walk in like this." ”

"Do you have a habit of cleaning at night or early in the morning?" Gu Chen asked him.

I have long seen that the tiles on the ground are a little shiny, which is obviously the effect of mopping the floor.

"That's right, once in the morning. ”

"What did Zhang Guowen do with you last night?"

"That's it...... Tell me a little bit about the details of your work. ”

"Talking about work?"

"Yes, talk about work. ”

Gu Chen came to the hall and used his master-level observation power to search the surrounding environment.

Surprisingly, the whole hall was clean and tidy, and everything was neatly arranged, which is difficult to do if you are not an obsessive-compulsive person.

Xu Yun's smile gradually disappeared from the moment she entered the door, and she beckoned everyone: "Sit down, don't stand, sit on the sofa casually." ”

"No, we've been sitting in the car for a long time, and now it's like standing and moving. In order to cooperate with his nonsense, Officer Wang even twisted his body.

After all, everyone doesn't want to destroy the scene, at least they want to find out what the problem is first.

Gu Chen's eyes prompted, Lu Weiwei and Yuan Shasha, and quickly walked to the top of the attic to check.

Officer Wang pushed open the door of the bathroom, which was a must-have place for inspection.

As for Gu Chen, he stood in front of Xu Yun, pointed the law enforcement recorder in front of him, and continued to ask, "Do you need to talk about work at night?"

"Well, because it's a tricky question, it's related to my assessment in my new unit. ”

"What did you say?"

"That's it...... It's about some attention beforehand, after all, I'm a new employee. ”

"Then why don't you work in the old unit and transfer to the new unit?"

"It's because ...... It's because it's close to home. ”

"But it's almost the same distance from the new and old units. ”

Xu Yun: "......"

"And you have the work experience and connections of the old unit, wouldn't it be better to stay there?"

Xu Yun: "......"

"You're not telling the truth?" Gu Chen looked at Xu Yun in front of him, and Xu Yun's whole person was panicked.

However, she quickly adjusted her state, and said with a light smile: "Gu ...... Officer Gu, can we change the way of communication, so that I will feel that you are interrogating me, I am a little nervous. ”

"Then take it easy, I'm not interrogating you now, I'm asking you about the situation. ”

"Yes...... But you're searching. ”

"That's because this is the place where Zhang Guowen last disappeared, and we also asked the security guards, there are no surveillance cameras in the elevator, and you drove out again after you came back last night. ”

Xu Yun: "......"

What else can be said?

Gu Chen almost dominated the topic.

And Xu Yun, who seemed to be cheerful and good at communication yesterday, is unusually and too restrained today.

Even when Xu Yun talked to Gu Chen on the phone in the morning, she teased Gu Chen from time to time, looking the same as yesterday, and there was not much personality contrast.

Until everyone entered Xu Yun's residence, Xu Yun's whole person looked a little flustered, and he didn't even dare to look directly into Gu Chen's eyes.

"Have you investigated me privately?" Xu Yun asked as she looked at Gu Chen.

Gu Chen nodded slightly: "We found you here according to the location where Zhang Guowen finally disappeared, and then Zhang Guowen did not leave the surveillance screen of the apartment, only the picture of you driving away, how do you explain this?"

"I don't know. Xu Yun shook his head, and said unconsciously: "He only stayed with me for a lot of time, and then went out, as for where he went, I don't know." ”

"Then I felt depressed, so I drove out and stayed late at a nearby 24-hour restaurant. ”

At this time, Lu Weiwei and Yuan Shasha came down from the attic.

The two shook their heads at Gu Chen.

Obviously, the two of them had nothing to gain from it.

Officer Wang also came out of the bathroom.

From the facial expression, Gu Chen could roughly guess that Officer Wang was the same.

Clean room, which seemed to be cleaned spotlessly clean, made one feel very curious.

Xu Yun, who went home late last night, cleaned up again this morning.

And Zhang Guowen last night did disappear from the apartment, and finally appeared on the river.

Thinking of this, Gu Chen's expression suddenly turned stunned, and he asked Xu Yun, "Do you have a car?"

"Right...... That's right, a second-hand car. Xu Yun looked even more flustered.

"But why did you leave your car behind and take a taxi to work? And you went shopping yesterday and didn't drive, what the hell is going on?"

In Gu Chen's opinion, Xu Yun has many questions that are difficult to understand.

People who have a car, but choose to take a taxi to commute to work.

But Xu Yun gave her own explanation.

"I only want to drive a used car when I want to go out and relax, and if I have a party with friends, I might think about drinking, so I don't want to drive, and I don't want to hire a substitute driver. ”

"As for not driving to and from work, it's because I'm not skilled at home, and I have no problem driving on the road, but parking is nerve-wracking. ”

"Every day with a group of old drivers to grab a parking space, I can't win, sometimes it takes about 15 minutes just to reverse in the parking lot, so ...... So I'd rather get to work, take a taxi or take the bus or subway. ”

"After all, it's just a way of life for me, and everyone has their own way of life, doesn't it?"

"Okay. Gu Chen respected her, but continued to ask, "Where is your car?" I want to check your car. ”

"Uh......"

"What's inconvenient?" Seeing Xu Yun's complicated expression, Lu Weiwei hurriedly asked her.

Xu Yun shook her head: "No, I just feel that you don't trust me a little." ”

"We're not targeting you, we just need to get to the bottom of things. Gu Chen also sensed Xu Yun's rejection.

Xu Yun sighed.

At this moment, she had no choice but to cooperate with the police investigation.

After some ideological construction, Xu Yun still agreed.

......

......

At Xu Yun's residence, everyone found nothing, mainly Xu Yun's obsessive-compulsive disorder and cleanliness habits, which hindered many work.

If it was said that Xu Yun deliberately cleaned the room, she didn't admit it, and no one could ask for it.

After all, Zhang Guowen has been here, this is a fact.

But where did Zhang Guowen go after that? No one knows.

In addition, the elevator was not monitored, so Gu Chen suspected that Zhang Guowen might have been killed in Xu Yun's room, but he was taken to another location by Xu Yun and thrown into the river.

Of course, the body will be handed over to the technical department of the city bureau, and it will also provide itself with data support.

Now what Gu Chen has to do is to find Xu Yun's vehicle.

After all, in the surveillance screen, Xu Yun did drive away from the apartment alone.

......

......

"This is my car. Xu Yun took out the car key and unlocked it easily.

Gu Chen walked directly to the car and gently touched the paint with his hand.

"You car...... Just cleaned?" Gu Chen felt sloppy.

Xu Yun not only cleaned the room in the residence, but even the vehicle, which in Gu Chen's opinion, she didn't want to leave any clues to herself.

Xu Yun's explanation was expected, she said with a light smile: "I stayed in the restaurant for a long time last night, and when I went home, I felt that the vehicle had not been cleaned for a long time, so I drove to a nearby car wash and cleaned the vehicle well, and my mood suddenly improved." ”

Seeing what Xu Yun said, Gu Chen did not respond, but directly opened the trunk and began to inspect the interior of the vehicle.

It stands to reason that if Zhang Guowen was in the car last night, it would definitely leave some visible clues.

But now it seems that everyone seems to have underestimated Xu Yun's ability.

This car has been cleaned almost inside and out.

In particular, Gu Chen carefully inspected the positions on both sides of the vehicle.

After all, if Zhang Guowen is lying upside down in the car, then the place where the shoes touch must be the sides of the vehicle.

But it's a pity that in these places where there should have been scratches, Gu Chen found nothing.

Including the rear seats, it is almost clean like a new car.

"You cow. Gu Chen couldn't help but give a thumbs up, feeling that Xu Yun was laughing in his heart, right?

Although there are various signs on the surface, Zhang Guowen's death is inseparable from Xu Yun.

Even Zhang Guowen's body is likely to be hidden in Xu Yun's car and taken away, and then thrown into the river.

But at present, the few details that Gu Chen investigated have been cleaned up, and there is no way to start at all.

Seeing that Gu Chen was a little embarrassed, Xu Yun breathed a sigh of relief, and also tried to calm down and said, "Officer Gu, so now, do you need my assistance in the investigation? I still have to go to work, but I asked for leave." ”

"You said that Zhang Guowen was drunk, urinated by the river, and accidentally fell into the river, but we did not find any trace of Zhang Guowen in the bar street along the river road. ”

Officer Wang walked from behind Gu Chen and also looked at Xu Yun with a serious face.

"No?" Xu Yun was stunned and said weakly: "Then I don't know what's going on?" After all, he used to do that, so I would think it was like this. ”

"But since this is not the case, then I don't know what the situation is, why did the master die on the river, this ...... I really don't know. ”

"You ......"

"You go back first, we'll call you again if there's a situation." Before Officer Wang could finish speaking, Gu Chen directly interrupted.

Xu Yun nodded silently: "Then thank you Officer Gu." ”

Gu Chen opened the transcript, handed it to Xu Yun with the pen, pointed to the bottom row of spaces and said, "Write down your phone number, so as not to find you through Wang Shaofei." ”

"Good. Xu Yun nodded silently and did as she was told.

Then he handed the transcript to Gu Chen, and said with a light smile: "Then I will drive to the bank to work now, do you have any opinions?"

"Of course...... No comments. Officer Wang also said with a bitter gourd face.

I feel that this little girl is much more powerful than I imagined.

Originally, everyone had already followed the vine, and everyone originally thought that they could find clues in Xu Yun's residence.

But it backfired. It seems that everyone is overestimating their own level.

And Xu Yun, a weak woman who looks ordinary, seems to have done everything in many ways.

And since Gu Chen spoke, everyone had no more opinions, watching her drive away from the front until she disappeared around the corner of the underground parking lot.

"Senior Brother Gu, if we let her go like this, there must be something wrong with her. Lu Weiwei felt very depressed, and said in her heart, how could this be?

Originally, I thought that this was the end of the investigation, but now it seems that this is just an interruption of the investigation.

Gu Chen smiled lightly and said, "It's okay, we can't find clues here, we can also start from the corpse of the deceased Zhang Guowen." ”

"You mean when and how you died?" asked Officer Wang.

Gu Chen nodded slightly: "Diatom detection technology, we still have to continue to use it, we can't learn it in vain." ”

"It is estimated that Forensic Doctor Liu and Gao Chuanfeng are already starting. Yuan Shasha said.

......

......

Leaving the apartment, everyone was not idle, and drove directly to the technical department of the city bureau.

At this moment, the testing room is busy.

Detection seems to be coming to an end......

When Forensic Doctor Liu saw Gu Chen coming, he also smiled lightly and said, "I just wanted to inform you to come over, but you came over first before you arrived." ”

"We have a heart. Gu Chen walked up to Forensic Doctor Liu and said teasingly.

"How is Forensic Doctor Liu? How did this Zhang Guowen die?" Lu Weiwei came here to find the answer, so she went straight to the point.

Forensic Doctor Liu took off his white gloves, took a sip of a glass of water, and then explained: "Of course this Zhang Guowen drowned. ”

"Drown......ing? Why is this still drowning?" Yuan Shasha originally thought that Forensic Doctor Liu would give a different result, but it didn't seem to be.

Officer Wang also frowned and asked, "In that case, this Zhang Guowen did fall into the river and drowned?"

Forensic Doctor Liu smiled faintly and didn't say too clearly.

Gu Chen asked him curiously: "Forensic Doctor Liu, have you done diatom testing?"

"Yes. ”

"What about the result?" Gu Chen asked again.

Seeing that everyone was nervous, it seemed that they had come back from a wall outside, so he explained with a light smile: "How can it be so fast? Isn't this making Gao Chuanfeng stepping up testing?"

"What about the time of death?" Gu Chen also asked curiously.

Due to the urgency of the time, many tests were left to the technical section of the municipal bureau.

Now this parameter seems to be the crux of the case.

But before Forensic Doctor Liu could speak, Gao Chuanfeng, who was doing experiments on the testing table, said: "The time of death, I have repeatedly verified with my master and determined that the time range was between 9 o'clock and 10 o'clock last night. ”

"Between 9 o'clock and 10 o'clock?" Hearing Gao Chuanfeng's words, Gu Chen seemed to think of something again.

For the judgment of the time of death, Forensic Doctor Liu has rich experience, which Gu Chen cannot question.

But as soon as this result came out, it was completely different from the result that Gu Chen got before.
