Chapter 100 Mandala 20

In the afternoon, Donglan City Bureau.

The police officers of the task force evacuated from No. 3 Middle School as quickly as possible.

After packing up her things, Luo Siwei returned to the office and hurriedly took Tang Xi to see Chi Li.

She knocked on the office door, and Chi Li shouted, "Come in." He asked the two of them to sit opposite each other at the desk.

"I've been reviewing the cases the city police investigated recently and have made some new discoveries. They're about the previous murder case."

"A murder in a murder house?" Both of them were a little surprised and said in unison.

Tang Xi asked directly: "Hasn't that been resolved?"

Luo Siwei didn't expect that the previous case was related to the case they were investigating now.

"As for the clues, they were provided to me by you guys," Chi Li said. "Captain Luo, remember when we searched for evidence, we couldn't find Xie Chenyu's laptop."

Luo Siwei nodded. She had written this point into the case report. Bank account information indicated that Xie Chenyu had purchased a laptop, and Zheng Wanshan's confession confirmed this. However, during the evidence search, the officers searched repeatedly but ultimately failed to locate the laptop.

Chi Li said, "When I was reviewing the situation recently, I found a detail mentioned in your investigation report. Xie Chenyu would take Zheng Congcong to an art class every Saturday afternoon. Usually, she would go to a nearby coffee shop and wait for the whole afternoon."

Luo Siwei nodded. This was also the information the police had obtained during their previous investigation.

Chi Li explained, "I asked Team Yu's team to go check the coffee shop again. The surveillance footage there is retained for six months, so they retrieved footage from a certain period of time and found Xie Chenyu there. On several occasions, Xie Chenyu was operating the computer in the coffee shop, which led to new findings."

This was information that Luo Siwei had not obtained before. After the case was solved, she did not check the surveillance video of the coffee shop again.

But the water is deeper than she imagined, and the case is more complicated. Important information is hidden behind the tiny actions.

Chi Li found that there were still doubts and completed this investigation link.

This is how you investigate a case. You need to be extremely careful and not miss any possible clues.

After introducing the basic situation, Chi Li opened the surveillance footage on his computer.

Luo Siwei and Tang Xi stared at the screen intently.

In the picture, Xie Chenyu was drinking coffee and playing with her mobile phone. Several times, she took out a small laptop from her schoolbag and typed on it.

The missing notebook finally appeared.

There are several such videos.

Chi Li opened another video and gave them a hint: "Pay attention to this video."

The video shows Xie Chenyu's side profile. From this angle, the main screen cannot see what is open on her screen. One can only see that her expression gradually becomes serious, her lips are slightly pursed, her eyes are fixed on the laptop screen, and then she types on the keyboard.

After a while, she raised her head with some vigilance, adjusted her sitting posture, and then she was blocked by a pillar beside her.

The whole process is very short, only about one and a half minutes.

Luo Siwei noticed something. The cafe had a lot of mirror decorations to increase the indoor lighting.

She used the mouse beside her to pull back the video playback bar: "The mirror behind her captured her screen!"

Chi Li pointed and said, "And here, the glass mirror on the upper right captured her typing movements."

They could tell from Xie Chenyu's actions that she had typed some text.

Luo Siwei pulled the video back again, played it at a quarter of the speed, and watched it carefully.

Tang Xi was more sensitive to the layout of the keyboard. He whispered to the side: "d...i...y...u..."

Luo Siwei thought of the progress Chi Li mentioned on the phone before, and suddenly realized: "She logged into the operating background of the Whispering software! She is a Whisperer!"

In previous investigations, Luo Siwei and his team only found clues from the users. This was the first time they came into contact with the people hiding behind the software.

Thinking back carefully, Xie Chenyu does fit the profile of the Whisperer.

Chi Li said, "I spelled out the login address based on the reflection on the coffee shop glass. Then, based on the pattern of Xie Chenyu's finger movements, I guessed her login name and password."

Luo Siwei asked, "Captain Chi, what should we do now?"

Chi Li said: "Xie Chenyu has passed away, but it is possible that her ID has not been cancelled. Let's prepare and log in. That's why I called you here today and let Tang Xi do the operation."

Since the website is hosted abroad, some special software is required to log in.

Chi Li and Tang Xi discussed the technical details, including how to record the screen and hide information.

Then Tang Xi entered the URL into the desktop computer next to him.

It was the first time that Luo Siwei saw the backend login interface of the Whisper software. The entire page was very simple, with only three colors: black, white and red. The background was black, the font was white, and the red was the key mark.

There are two login ports on the web page. The upper login port is two white boxes side by side. It is the administrator's entrance and requires filling in the user ID and password.

In the past, the police only obtained the login accounts of ordinary mobile phone users. Those accounts could be cancelled by the administrator at any time and would be automatically deleted, so they had no access to much internal information.

They all hope that there will be some breakthroughs this time.

Tang Xi moved his fingers, started the relevant program, carefully clicked on the login box, entered the account name and password that Chi Li had written down before, and then clicked Enter.

The interface suddenly brightened.

A login message popped up on the webpage: "Welcome, Whisperer Xie Chenyu. You can perform operations management."

Whisperer, Operations Management...

It seems that the police's inference is correct. The so-called whisperers are actually higher-level operators.

After Tang Xi completed the operation, a new interface opened.

"Go in!" He couldn't help but get excited.

This was exciting news. The three people looked at the page on the screen. The upper part was the public channel webpage, and the lower part was a dialog box where you could select a name to chat with someone individually. On the right was the operation bar.

With administrator status, all the information inside can be viewed directly. Each user name displayed is the real name, followed by their mobile phone number and ID number.

In the eyes of those people, the identity of netizens is like the emperor's new clothes.

Each post can be deleted, pinned, etc., and there are also functions such as site-wide announcements and hacking into mobile phone systems.

Luo Siwei looked at the information above, line by line of text, and got goosebumps. She was extremely shocked.

Then she looked serious and thought intently. Xie Chenyu had been carefully hiding her identity. How could she register with her real name? Or did someone else already know her identity?

It is even possible that those people knew what she had done because she had killed two people, so Xie Chenyu was recruited by those people and joined the Whisperer organization?

Xie Chenyu later quit her job and has been doing these things ever since?

Her mind was still analyzing the problem rapidly when a new line of text suddenly appeared on the screen: "Account abnormality. The login point is not your usual login location. Please enter your security number. If you do not enter it or enter it incorrectly, your account will be automatically logged out in 60 seconds."

Tang Xi turned around and looked at Chi Li anxiously: "How should we deal with this?"

They hadn't anticipated the other party using a security code. In their previous investigation, they hadn't even found Xie Chenyu's computer, let alone a security code. But this was their only clue about the person behind the scenes.

Chi Li wanted to know more information, so he made a quick decision: "Can I get the list? Or the chat history..."

Tang Xi tried to open the program interface, his fingers flying on the keyboard.

Time flies by second by second, only a minute...

At the same time, the woman sitting in front of the French window gasped for breath, her face pale, her fingers trembling. She found it hard to believe what had just happened, but it really happened.

This afternoon she received the news that the police had withdrawn from No. 3 Middle School and had just breathed a sigh of relief, but she didn't expect such a change to happen just a few hours later.

Those policemen are so difficult to deal with.

After adjusting her mood, the woman took out her cell phone and quickly made a call.

A man's unhappy voice came from the other end. He lowered his voice and said, "Didn't I tell you not to make this call casually?"

"Something happened." The woman's voice trembled. "Someone just logged into Xie Chenyu's account. Isn't she dead..."

"Don't panic," the man said. "It's okay. I've already recovered her device. It has a security feature in the backend. They can't operate it."

The man said this to comfort the woman, while his mind was quickly sorting out the matter.

Since Zha Junxi was arrested, the system has not been maintained and has not been upgraded for a long time. This is their oversight.

After they discovered Xie Chenyu's account hadn't been logged in for two days and she had lost contact, they rushed to retrieve the relevant items before the police arrived. They had the phone and security code in their possession.

But how was Xie Chenyu’s account discovered by the police?

This was a dangerous sign that the police had dug deeper than he had expected.

"The login lasted about a minute, and the security protection was activated." The woman on the other end of the phone finally breathed a sigh of relief.

"Don't worry, everything will be fine." The man comforted her, "It's almost over."

He hung up the phone and stared at the clock on the white wall with a cold look. Time was ticking away. He had to speed up. He had to cut off their clues at all costs.

In the office of the detachment commander of the Municipal Bureau.

The keyboard was clattering.

Looking at the scene in front of him, Tang Xi broke out in sweat.

One minute is too short.

The screen went dark, and Tang Xi said regretfully, "The account was popped up..." Time was limited, and he couldn't even enter a few lines of code.

Chi Li comforted him: "It's okay, entering the website is already a big progress. Did you record the screen just now?"

"I recorded it." Tang Xi said as he opened another file. "But it's not all in vain. I got some information about the website's architecture."

This sentence undoubtedly ignited their new hope.

Chi Li and Luo Siwei lowered their heads and looked at the screen.

Tang Xi pointed at the codes above and said, "This is the structure tree of the entire website. From the numbering, we can infer that the website's structure is: one webmaster, one maintainer codenamed MYD, and then four senior administrators represented by the symbols X, Y, Z, and M. Below them are several administrators of various sections, but their authority is not as high as these people. We just logged in with account X."

"MYD stands for Cha Junxi, and Xie Chenyu is X. So are these initials? Or did they come up with their own names?" Luo Siwei asked. "Who is the webmaster?"

Tang Xi said, "It only wrote the words 'Stationmaster'."

Chi Li stood up and said, "Don't worry, once this road is opened, there will be more breakthrough points."

Luo Siwei nodded. "We can analyze the information line by line. When did Xie Chenyu start contacting these people? How did she do something about it? Did these things cause her personality to change drastically? There must be clues we can investigate."

After all, Xie Chenyu was the first Whisperer they found. Although she had died, this was indeed a great progress in the investigation.

Chi Li stared at the website structure tree: "If we continue to investigate, we will be able to find the true identities of these people."

In the past, they were in the light and those people were in the dark.

But now, we have to be very careful and cautious.

They were one step closer to the person behind the scenes.

In the afternoon at the Third Middle School, the school bell rang and the students quickly picked up their backpacks and walked out of the classroom in twos and threes.

Someone called out to a girl sitting in the middle: "Yu Tingting, do you want to go together later?"

Yu Tingting raised her head: "No, I have something else to do today, I want to go home by myself."

The classmates left in groups of three or four, and the girl slowly packed her schoolbag. She walked out and slowly moved towards the psychology classroom.

After a fierce psychological struggle, Yu Tingting decided to go to the police and surrender herself.

She walked to the door of the psychology classroom, took a deep breath, reached out and pushed the door open.

The door is locked.

Yu Tingting suddenly panicked, and the mental preparation she had made long ago collapsed in an instant.

She turned her head and stood helplessly in the dark corridor. The light from the end of the corridor cast a long shadow behind her.

Yu Tingting was a little scared of a wall not far from the psychology classroom, where a strange painting was hung.

She chose another direction, and just as she turned around, she saw a tall, thin man standing in the shadow of the corridor, almost silently.

She was startled, then recognized that it was the teacher in charge of several nearby art studios.

Yu Tingting asked in a trembling voice, "Hello, teacher. I want to ask, where did those police officers go?"

The male teacher turned around, his face pale. "Police? Looks like they've gone back?"

"What...when?" Yu Tingting asked in a trembling voice.

"This afternoon, right? They've all left and moved their belongings. Their investigation is over." The male teacher lowered his head and asked her, "What do you want to talk to them about?"

"No, no..." Yu Tingting said hurriedly.

She felt guilty, like a snail that had just mustered up the courage to stick its head out of its shell, waving its tentacles, and then hurriedly retracted into its shell.

Yu Tingting was so panicked that she turned around and wanted to run away.

The person behind him laughed: "You are going on an autumn outing tomorrow, remember, be prepared."
