Communicating with Smart People is a Breeze

Although there were some minor incidents during the arrest operation, it ultimately ended without serious problems.

Li Yuanliang had clearly overestimated himself and underestimated the durability of domestic glass.

Domestic glass isn't something that just anyone can break through with a single impact!

After apprehending Li Yuanliang, the officers immediately regrouped and drove straight to the police station.

Meanwhile...

At the police station.

Xu Mo had already obtained the evidence and returned to the station ahead of Han Fei.

He had handed over the cake and roses found in the vase from the villa to the forensic team to test for the presence of ricin toxin that had killed Guan Yiliu.

Half an hour later, the forensic results came in.

"Here's the examination report. Take a look - both the cake you brought back and the rose stems contain high concentrations of ricin toxin..." the forensic expert found Xu Mo and informed him of the test results for the cake and roses he had brought back.

After a pause, he continued.

"Additionally, I took another careful look at Guan Yiliu's body and found an inconspicuous puncture wound on her right palm, likely caused by the rose thorns. This was probably the cause of her death."

Xu Mo wasn't surprised by the forensic results - he had seen the surveillance footage and knew Li Yuanliang's poisoning method.

Having the forensic team examine the evidence was merely for procedural thoroughness. They needed professional test results to convict Li Yuanliang.

Verbal testimony and untested items alone wouldn't be sufficient.

Just as Xu Mo was reviewing the test report, Han Fei's team returned to the station with Li Yuanliang in handcuffs.

"Captain Han, perfect timing," Xu Mo turned to Han Fei, waving the test report. "We've gathered all the criminal evidence against Li Yuanliang. We were just waiting for you to bring him in."

Hearing this, Han Fei quickly walked over to Xu Mo's side.

He took the forensic report from Xu Mo and began reading it.

While Han Fei was reviewing the report, the forensic expert explained the technical details, worried that Han Fei might not fully understand the professional terminology.

"Captain Han, look here - these are the test results. The examination confirms that both the cake and rose stems Xu Mo brought from the scene contain high levels of ricin toxin."

At this point, the forensic expert gave Li Yuanliang a meaningful look.

When Li Yuanliang, still in police custody, heard the words "cake" and "roses" and noticed the forensic expert's glance, panic flashed across his face.

He knew these items all too well... they were the poisoned items he had used in his murder attempt!

The police have found the ricin-laced cake and roses, and they've arrested me... have they already gathered evidence of my poisoning? How did they suspect me? Li Yuanliang couldn't figure it out.

He had deleted the surveillance footage, after all!

He wasn't surprised that the police hadn't been misled into ruling Guan Yiliu's death as natural causes.

After all, while ricin toxin was difficult to detect through medical means, it wasn't impossible.

A thorough forensic examination could certainly detect ricin toxin.

He also wasn't surprised that the police had found these two poisoned items at the scene.

What truly puzzled him was why the police had suspected him in the first place.

He had deleted the surveillance footage from the community, and no one knew about it - he had done it secretly when no one was watching.

Moreover, he had quit his job before the police had even discovered Guan Yiliu's body.

He had done this because he didn't trust his own psychological fortitude - he didn't dare to continue working as a security guard in the community or face the police while acting as if nothing had happened after committing murder.

He feared that some particularly perceptive officer might notice his unnatural behavior and become suspicious.

But what Li Yuanliang hadn't expected was...

How had they found him despite his deleting the footage, quitting his job, and avoiding contact with the police?

And from the officers' tone, Li Yuanliang sensed that they weren't merely suspicious of him.

It seemed more like they had already determined he was the killer!

In fact, Li Yuanliang's guess was correct.

The police had indeed confirmed that he was the murderer.

After reviewing the test report, Han Fei instructed the officers behind him: "Take him to the interrogation room. I need to discuss something with Xu Mo, and I'll be there shortly."

"Understood," Li Chen nodded and led Li Yuanliang to the interrogation room.

The other officers who had participated in Li Yuanliang's arrest returned to their respective workstations.

Han Fei's next task was to interrogate Li Yuanliang, but before that, he needed to align with Xu Mo.

After all, regarding this case, his understanding wasn't as comprehensive as Xu Mo's.

How could they conduct an interrogation without first clarifying all the leads?

Before Han Fei could speak, Xu Mo had already understood his intention.

"I've saved that deleted footage on a USB drive. Would you like to watch it before we interrogate Li Yuanliang?"

"Yes!" Han Fei smiled.

It was so efficient working with smart people!

He hadn't even said anything, and Xu Mo had already guessed his thoughts.

No need for explanation at all!

Then, Xu Mo plugged the USB drive from his keychain into the computer and played the surveillance video he had recovered using technical means earlier that day.

While showing the video to Han Fei, Xu Mo also explained everything he knew.

"This is footage from midnight yesterday. Li Yuanliang tricked the guard on duty by saying he had lost something in the community and needed to find it. After entering, he went straight to Guan Yiliu's villa and left the ricin-laced cake and roses at her door... Li Yuanliang deleted this footage early this morning in the surveillance room. He put laxatives in his colleague's breakfast, and while his colleague was in the bathroom, he replaced this surveillance footage..."

Five minutes later.

Han Fei nodded, having understood Li Yuanliang's entire crime process from Xu Mo's description.

"Let's go interrogate Li Yuanliang. Come with me."

Although the evidence was already quite substantial and Han Fei knew Li Yuanliang's entire crime process.

Logically, interrogating Li Yuanliang should be straightforward.

They could simply present the evidence to him without much discussion, and Li Yuanliang would likely confess voluntarily upon seeing it.

But Han Fei still invited Xu Mo along.

The main reason was... all the key clues in this case were discovered by Xu Mo.

It could be said that without Xu Mo, Han Fei might have needed to go in circles before uncovering the truth.

So Han Fei asked Xu Mo to join him in interrogating Li Yuanliang, primarily to avoid anyone thinking he was taking credit for Xu Mo's work.

Xu Mo naturally didn't refuse Han Fei's invitation and stood up to walk with him toward the interrogation room, ready to question Li Yuanliang.
