Chapter 702: The Post!

Chen Xiao sat in the room.

Holding the portrait in his hand, he hadn’t moved for a long time.

In the case, the only person who fit the image of a young man was Sang Xiaoming.

And Sang Xiaoming held a very special position in the case.

Because after the deceased came to Xiaozhuang South Town, he had contact with him, even having had an exchange.

However, there was no valuable information in Sang Xiaoming’s testimony.

This doesn’t necessarily mean that Sang Xiaoming was lying.

He is a student, and his father inviting the tenant Yuan Keyu to teach him some academic knowledge is a very reasonable thing.

However, who tampered with the surveillance at Sang Yupeng’s house?

Although tampering with the surveillance is not difficult, and from watching the video, it doesn’t seem like fake footage.

So, the problem with the video, or to directly say the illusion of a locked-room murder, merely involved swapping the surveillance.

The cameras on the fourth and sixth floors were swapped.

And the camera on the actual fourth floor had long since been broken and had no footage.

This resulted in an almost perfect locked-room murder case.

The more Chen Xiao thought about it, the deeper he delved.

Unknowingly, it was already dawn.

That night, nothing happened after all, nor was there any news.

As Chen Xiao was finally about to relax a bit and catch some sleep, Xie Wensheng’s call came through.

Chen Xiao answered immediately.

A call from Xie Wensheng could only mean that the company’s technical personnel had found the forum or even the conversation between the deceased and the killer.

"Hello, Brother Sheng, is it good news?"

"Sort of. When I received your call last night, I had the company’s entire technical team work overtime to look for clues online. It wasn’t until half an hour ago that a young man found the Professor Yuan you mentioned on an academic forum."

"Based on Professor Yuan’s ID, he discovered a suspicious person on another forum. It was in a thread conversation, and that website is also a domestic forum site."

"In the thread discussion on that post, there was a discussion about a question, and the time of the conversation was also after his return to the country. I’m going to send the content that the tech personnel captured to your computer, and see if those conversations seem suspicious. If so, we need to ask the relevant departments to intervene and connect with the site to see if they can provide the account details to find their private chat records."

While Chen Xiao was listening, he was also looking at the content sent by Xie Wenzheng.

Chen Xiao found some of the content difficult to understand because 90% of it was about discussing issues.

Moreover, the discussion had no resolution, and both parties only exchanged a few words before it abruptly stopped, with no further details.

The heated conversation that suddenly ended is the reason why Xie Wensheng suspected the two had private communications.

After reading it, Chen Xiao immediately said, "Okay, I’ll notify the task force right away to have them contact the website."

After speaking, Chen Xiao was about to hang up the phone but immediately said:

"Brother Sheng, thank you for your hard work."

"Don’t overthink it, I wasn’t staying up all night waiting. I only got up to call you back this morning when I received a call from the technician."

"That’s good. You need to take care of yourself! Oh, right, when salaries are paid this month, remember to give that technician a bonus, and also observe his performance for a while. If he continues to perform well, give him a promotion!"

"Don’t worry, I have my eye on capable people."

With those words from Xie Wensheng, Chen Xiao didn’t say more.

The information provided by Dong’an’s technician needed immediate investigation.

After hanging up the phone, Chen Xiao got up immediately to find Qin Fei.

While Qin Fei was washing up, Chen Xiao conveyed the information to him.

Qin Fei wiped his face, surprised and delighted:

"I was right to ask for your help, and from this case, I suddenly feel there’s been a big change. Especially our ways of solving cases can no longer be limited to how they were before, the internet is also a very important place!"

Chen Xiao just smiled briefly but quickly asked:

"You don’t have any other news from the whole night?"

"No, nothing seemed to happen last night, otherwise I couldn’t have slept through to this time!"

Qin Fei said this and left with Chen Xiao to find Cao Xiuyuan.

The latter didn’t sleep the whole night and didn’t return home, instead, he was at the crime scene conducting a night-long trace investigation.

Seeing Chen Xiao and Qin Fei coming, Cao Xiuyuan put down the work he was holding.

However, he first took out his cell phone and placed it aside, then signaled for the two of them to speak outside.

Chen Xiao took a look and silently went out.

Once Cao Xiuyuan came out, he quickly asked: "You guys came to see me at this time, did you make a major discovery?"

"The technical staff at Chen Xiao’s company tracked down possible communication between Professor Yuan and the killer, but the content is very limited and requires us to contact the website and extract their private chat records."

Qin Fei explained to Cao Xiuyuan.

Hearing this, the latter was full of joy and asked: "It’s a domestic forum?"

"Yes, and their communication was after Professor Yuan returned to the country."

"Great, tell me the name of the website, I’ll get someone involved right now."

Chen Xiao was prepared for this and gave Cao Xiuyuan the website’s company and contact information together.

When the latter got it, he was about to take his cell phone, but then he remembered and smiled bitterly:

"My phone was tampered with, but I’ll tell you about that later, Qin Fei, give me your work phone for a call."

Qin Fei nodded and handed over his work phone.

Cao Xiuyuan took the phone and made a call to the side, and a few minutes later, he returned, and before Chen Xiao and Qin Fei could ask, he said proactively:

"Discovering my phone had issues was an accident. Shortly after arriving at Xiaozhuang South Town my phone inexplicably broke, so I went to a repair shop to take a look."

"As soon as the repairman opened it, he found the problem, and before I saw him, I already told him I was a cop, so he cautiously told me through writing that my phone had been fitted with a listening device."

Qin Fei couldn’t help being surprised: "Isn’t your phone always close to you? How could someone silently plant a listening device?"

"It’s carried for the most part, but not absolutely 24/7, so there must be a place that was used against me. Besides, the device inside my phone is very advanced, the repairman told me it’s the most advanced micro-listening device!"

As Cao Xiuyuan said this, his gaze shifted to Chen Xiao.

With that look, Chen Xiao seemed to understand what he meant and said:

"Captain Cao, you don’t have to look at me like that. You haven’t planned to tell us everything you know, so we won’t ask too much."

Upon hearing this, Cao Xiuyuan hesitated for a moment, then smiled bitterly and said:

"Sorry, after realizing my phone had issues, it’s hard to trust anyone. Of course, you were called by me, and I shouldn’t have been wary of you."

Cao Xiuyuan’s words indicated he wanted to take this opportunity to open up and chat a bit with Chen Xiao and Qin Fei.

However, at that moment, the phone left in the room by Cao Xiuyuan started ringing.

Heading into the room, Cao Xiuyuan picked up the call:

"Hello, Old Sun, what’s up?"

"Old Cao, can you reach Xiaohai?"

Hearing Sun Zhou’s voice on the phone, both Chen Xiao and Qin Fei’s expressions changed dramatically.

Especially Qin Fei, who hurriedly asked: "Who is Xiaohai? He can’t be a member of our special task force, can he!"
