"It's like... Indeed, I had never thought of it that way before. Tang Yuran didn't know what to say all of a sudden.

Before, she always wishfully thought that Qin Kai killed Xu Ziqing for some reason.

But if it is really like what Wei Zhongwen said, Qin Kai does not seem to have a reason not to continue to be with Xu Ziqing, and there is no reason to kill Xu Ziqing.

"So what do you mean... Didn't Ziqing be killed by Qin Kai? ”

"I didn't say that." Wei Zhongwen said, shaking his head. "I'm just guessing, what is the reason why Qin Kai didn't break up, if Xu Ziqing chooses to continue to be together, it will be very understandable, but Qin Kai, what is the reason why he didn't break up with Xu Ziqing?"

"I don't know..."Tang Yuran didn't know how to answer this question.

Tang Yuran never thought that her thoughts had always been so simple, she had never thought deeply about this problem and analyzed the motives and rationality in it.

Or rather, Tang Yuran didn't know how to analyze it at all.

For her, this kind of case may not be accessible for a lifetime. But fate is like this, Xu Ziqing's case is like someone playing a big joke with her.

A man who had never only known about academic research would have started such an investigation. In the past, this was something Tang Yuran couldn't imagine.

"Officer Wei, I'really... I have never thought about this problem, and I don't know why Qin Kai still chooses to continue to be with Ziqing since he has already fallen in love with other people. But since you asked me, I thought maybe I could help you find some answers from Ziqing's diary. Tang Yuran said, with a very serious look on his face. If he could, Tang Yuran really hoped that he could help.

"In that case, without further ado." After Wei Zhongwen finished speaking, he motioned for Tang Yuran to set off immediately.

"Okay."

Just after nine o'clock, the research room was already empty, and there were only a few people left.

Through Tang Yuran's relationship, Wei Zhongwen also successfully entered the internal research institute.

"I made a copy of the diary before handing it over to the police, but because it was a research institute's material, I left it here, so you can come here anytime if you want to see it." Tang Yuran guided Wei Zhongwen while explaining.

"Hmm." After listening to the other party's words, Wei Zhongwen didn't say much, just nodded slightly.

After a while, the two of them came to the reference room.

The data room is usually closed, and whoever wants to check the information needs to register in order to get the key to open the door, and Tang Yuran is the one who is responsible for keeping the key.

Tang Yuran skillfully opened the door of the data room. "Please come in, Officer Wei."

"Thank you." As soon as Wei Zhongwen entered the data room, he couldn't help but be shocked. The seemingly small room is filled with dense materials, no less than a small library.

"Just find a place to sit." Tang Yuran said as he walked to a bookshelf, just glanced at it, and then took down the materials displayed on it.

"Looks like you're a regular here." Seeing the other party's proficiency, Wei Zhongwen couldn't help but sigh.

"The more I come, the more familiar I become. And I put all these materials in place, so I know exactly what materials are placed where. ”

"Awesome." Wei Zhongwen couldn't help but admire.

"It's over, it's just my business." Tang Yuran replied as a matter of course.

"Yes, there is a specialization in the art industry. Without further ado, let's get straight to the point. Wei Zhongwen proposed.

"Hmm. This is a photocopy, you can ask me any questions. Tang Yuran said and handed the information to Wei Zhongwen.

"Hmm." After receiving the information, Wei Zhongwen didn't say anything more, but began to look through it quickly. He opened one random spot at first, and then quickly wandered around, as if looking for some key information.

"I'm familiar with this diary, if you want to find any location information, you can tell me." Tang Yuran reminded on the side.

"You said before that Xu Ziqing found out about the fact that Qin Kai was having an affair, right?"

"yes, do you want to see this part?"

"Well, please help me find out."

"Okay." Tang Yuran said, took the diary, just flipped through a few pages at random, and successfully found the contents. "Here."

"Awesome." Wei Zhongwen couldn't help but praise.

"Where, I've seen a lot, I'm just more familiar." Tang Yuran said, her tone was still a little unnatural, she was not very good at accepting praise from others. As if to cover up, she said: "The diary wrote in detail the ins and outs of Ziqing's discovery of Qin Kai's cheating, and by chance, Ziqing found Qin Kai's chat record with a girl, because the content above is more explicit, so Ziqing understood it at once." ”

Well, indeed, it's also very clear here, and at first she didn't want to believe it, so she chose to treat it cold. But a few days later, she found the ambiguous chat information between the two again. When things developed to this point, Xu Ziqing went directly to Qin Kai for a showdown. But—" Wei Zhongwen said, pausing suddenly.

"What's wrong, is there anything wrong?" Tang Yuran asked.

"This place seems a little strange." Wei Zhongwen said as he pointed to a certain sentence on the information. In this place, Xu Ziqing mentioned that after she found out about Qin Kai's cheating, she chose a showdown with the other party, but Qin Kai's reaction was very strange. It's as if Qin Kai decided that Xu Ziqing would not break up with him. ”

"When you say that, it seems that it is... But according to my understanding of Ziqing, if Qin Kai had really cheated, she would not be willing to continue to be with Qin Kai. ”

"But the truth is, judging by the diary, it looks like it didn't happen. The rest of the content is also silent on this matter. Wei Zhongwen added.

"Yes, it was a little strange when I watched it. When the content is written here, it seems to have suddenly stopped, and the writing style seems to be a little different. ”

"Writing style?" Wei Zhongwen asked inexplicably.

"Yes, every text has its own unique style, and this is part of our research, through the author's choice of words or grammatical habits, as long as there is enough textual information, we can predict whether a text is from the same person." Tang Yuran explained.

"According to your research, do these two parts of the content come from two people?" Wei Zhongwen asked with some excitement.

"I wish I had, but the truth is..."Tang Yuran said, his tone could not hide his disappointment.

"In other words, even though on the surface, the style has changed, according to the research, it still comes from the same person, right?"

"It can be said that if someone wants to imitate Ziqing's writing style, it is not impossible, and the other party can refer to the previous content and deliberately forge it."

"Logically speaking, this method does work, but in addition to this, it also includes the handwriting of the writer, and I think the police can do a handwriting test, and if even the handwriting belongs to the same person, then the possibility of counterfeiting should be very small."

"I understand, but sometimes it feels like this kind of thing is really unreliable." Tang Yuran said, and couldn't help but smile self-deprecatingly.

"Let's go on." Wei Zhongwen said, as if he wanted to change the topic. "In other words, after the showdown between Xu Ziqing and Qin Kai, the two did not break up, but chose to continue to be together, and, judging from Xu Ziqing's diary, after this, Qin Kai did not restrain himself, on the contrary, he would still have an affair with that girl."

"That's right, it's like Qin Kai isn't worried that Ziqing will break up with him at all." Tang Yuran said, his tone full of anger. "I don't know where he got his confidence."

"But the truth is, the two did not break up." Although it was not friendly to say this, Wei Zhongwen still told the truth.

"Actually, I felt strange from the beginning, I couldn't figure out why Ziqing would volunteer to be with Qin Kai. Qin Kai doesn't have a serious job, just like a gangster, no matter who looks at it, he will feel that the two of them don't match. ”

"Did you say before that Xu Ziqing loves luxury goods, whether it is cosmetics or all kinds of bags, they are all famous brands, right?" Wei Zhongwen asked as if he remembered something.

"yes, what's the problem?"

"Don't you think it's strange? If Xu Ziqing was just a high-speed rail attendant, how could she have enough money to support her life. ”

"Isn't that the case with girls in many cities now, using overdrawn credit cards to buy these goods?" Tang Yuran replied.

"But the fact is that we have investigated Xu Ziqing's credit card limit, and there is no excessive overdraft."

"Could it be Qin Kai? Impossible, how could Qin Kai be so rich, he didn't even have a serious job. Tang Yuran said in disbelief.

"Judging from Qin Kai's bank flow, there is no large amount of money in his account, but half a year ago, this card has been discontinued, and the time coincides with the time of Qin Kai's disappearance."

"I understand, that is to say, Qin Kai's real money transactions should be carried out through other bank cards." Tang Yuran suddenly realized.

"Therefore, the reason why Xu Ziqing can't do without Qin Kai is probably related to money."

"How is it possible, Qin Kai doesn't have any serious work, no matter how you look at it, it should be Ziqing raising Qin Kai." Tang Yuran seemed to be unable to accept this fact and defended.

"You can't just look at the surface, in terms of money, who of these two people has the upper hand, as long as you check the bank statement information of that 'Qin Hua', you can make it clear." In this regard, Wei Zhongwen prefers to believe the evidence he has seen with his own eyes.
