Chapter 686: Let’s Spot the Flaws Together!

Chen Xiao seemed to be just talking and didn’t have Qin Fei reach out to Yuan Keyu’s close family and colleagues.

The latter had somehow found a small blackboard and chalk.

Seeing this, Chen Xiao and Qin Fei began analyzing and taking notes in the room.

"Sang Xiaoming is currently in Zhushan City, attending Zhushan Third Middle School. His social circle includes family, teachers, and classmates."

"Of course, we don’t know much about Sang Xiaoming yet; he may have some broader social connections, which we’ll temporarily represent with symbols."

"First, concerning Sang Xiaoming’s family, we’ve met Sang Yupeng, but we haven’t met his mother, Zhou Lu."

"According to Sang Yupeng, Zhou Lu has also been in Zhushan City accompanying the study, and she hasn’t been working regularly. So, when questioning Sang Xiaoming, the task force might have also questioned Zhou Lu."

"Let’s set Zhou Lu aside for now and focus on analyzing the school relationship circle." Chen Xiao said, and Qin Fei began writing down a series of names on the blackboard.

Those names were all of Sang Xiaoming’s teachers from various subjects.

However, after writing them down, Chen Xiao frowned deeply.

"I still feel something is off." Chen Xiao voiced his inner feelings.

Qin Fei paused as he looked at the names and said,

"Yes, writing down these names makes me feel something strange too."

"We still haven’t grasped the key point."

"But isn’t the key point that Yuan Keyu unexpectedly met Sang Xiaoming? Ordinarily, even if they were to meet, it shouldn’t have happened so quickly."

"That means we’ve overlooked a certain key point." Chen Xiao continued to correct.

Qin Fei knitted his brows: "I can’t figure out what key point we’ve ignored."

Chen Xiao thought for a moment and seemed to talk to himself:

"When we came, we observed the surveillance. Regarding surveillance, we considered both time and space."

"These two elements were initially intended to identify any surveillance loopholes. But Yuan Keyu’s actions have repeatedly told us that the location he reached, the space we talk about, is problematic."

"Besides space, there are now doubts about the timing. For example, why did Yuan Keyu meet Sang Xiaoming as soon as he arrived here? This could also be rephrased: why did Professor Yuan Keyu, who had returned to the country for some time, choose this moment to come to Xiaozhuang South Town?"

"It’s important to know that earlier, Sang Xiaoming was on summer vacation. And just before the incident, it was during Sang Xiaoming’s first break after starting school."

"If the location was a deliberate choice for Yuan Keyu, then the timing didn’t appear to be as deliberate."

Qin Fei understood the implication of Chen Xiao’s words but still asked,

"Are you saying he might have only recently become aware of Xiaozhuang South Town, the house of Sang Yupeng, and his child, Sang Xiaoming?"

With Qin Fei’s words, Chen Xiao seemed to see things much clearer:

"Yes, that’s why I kept feeling like meeting Professor Yuan’s close family and colleagues. It seems that’s the reason!"

"Why don’t we go now..." Qin Fei started to suggest but then stopped himself.

Chen Xiao glanced at him, smiling: "Once we get there, we’re not sure what to ask, right?"

"Yes, we’ve gone through the case files. The police inquiries are thorough. If we meet them, the questions we can ask don’t go beyond those, equating to meeting them and just asking redundant questions." Qin Fei said helplessly.

"We need to change the angle of inquiry, and as time passes, the family’s emotions will become increasingly impatient, to the point they might not want to talk to us anymore," Chen Xiao sighed.

For a moment, neither of them knew what to do next.

Chen Xiao looked at the scene and then walked to the window.

Through the window, Chen Xiao saw a large expanse of buildings.

Most of those buildings were low-lying factories, but in the distance, commercial housing was starting to be constructed.

Standing by the window, Chen Xiao couldn’t see anything different.

Standing here, could one perceive the unique scenery of life?

Did he come to the low-rent district because everyone here had entirely different life experiences from Yuan Keyu’s?

Chen Xiao didn’t think so, and neither did he believe that Yuan Keyu was fascinated by peculiar interests; his work wasn’t focused on social customs and culture.

He was engaged in scientific research.

It was said that the technology he mastered was extremely scarce in the country.

That’s why he was invited back to contribute to the nation!

Looking at those low-lying buildings outside the window, although everything now seemed calm, if the case remained unsolved without any conclusion.

Then Xiaozhuang South Town, this urban town, would face extremely harsh consequences.

So, the calm before him was just the calm before the storm.

Solve the case!

Solve the case!

For the first time, Chen Xiao repeatedly pondered these two words in his mind.

But solving the case required a breakthrough, and this was the same problem perplexing the elites of the East Province police force currently.

Yuan Keyu’s status was not ordinary.

The murder he encountered required many people to consider multiple levels.

Was it an old vendetta across many years, or was Yuan Keyu killed because of his talents?

If it’s the latter, then the level involved might be beyond what Chen Xiao or even Cao Xiuyuan could reach.

Moreover, this aspect needed to be verified at the onset of the case, and the verification wouldn’t be limited to criminal police alone.

Now that so many days have passed without the case being characterized, it indicates a low possibility of talent-related murder.

Disregarding the talent-related theory, why would a place almost unrelated to Yuan Keyu result in his demise?

What story existed in Xiaozhuang South Town that attracted Yuan Keyu’s arrival?

Thinking about these issues, an image from surveillance inexplicably popped into Chen Xiao’s mind.

Frame by frame, the images recalled in Chen Xiao’s memory, but those memories became increasingly blurred.

He didn’t know how much time had passed.

Whether it was a premonition or breakthrough advancements in Dong’an’s technology, thanks to substantial funding from Chen Xiao.

At this moment, Chen Xiao received a call from Xie Wensheng!

"Hello, Chen Xiao... the video has been partially optimized. I was worried you needed it urgently, so I processed the key parts and sent them to your email."

"What’s the clarity like?" Chen Xiao was most concerned about this.

Xie Wensheng replied, "While Dong’an’s current technical capabilities can’t be considered top-tier, the company’s technical personnel are all outstanding, so after watching the optimized video, you’ll notice a distinct difference."

Xie Wensheng didn’t speak directly.

But these words were already conveying good news to Chen Xiao.

Chen Xiao didn’t say much, immediately taking out his computer.

He opened the optimized video but didn’t sit down to watch; instead, he called out to Qin Fei:

"Captain Qin, stop dwelling on those temporarily unsolvable issues, come... let’s spot the flaws together!"
