The photo of Ji Gaolang's son Li Yuanliang that Han Fei found using the police system directly confirmed Xu Mo's suspicion.
The little boy in the family photo was the security guard who had hastily resigned from the community just this morning.
A child abandoned by his father at a young age, who could only rely on his mother, applies for a security job at the community where his father owned property after his father's death, and then hurriedly resigns on the day his stepmother dies of poisoning... It's too suspicious, making it hard not to suspect him.
He had both the motive and the opportunity to commit murder.
Now it can be basically confirmed that he is undoubtedly the killer.
Of course, to convict him, they still need to find evidence of his crime.
Without evidence, the police can't arbitrarily convict someone.
"I plan to check the community's surveillance footage and try to recover the segments that Li Yuanliang tampered with as soon as possible," Xu Mo said.
Li Yuanliang was a security guard in the community.
According to Xu Mo's guess, the reason why the police couldn't find anything when checking the community surveillance earlier was because Li Yuanliang had deleted or replaced the footage.
And that segment of surveillance that Li Yuanliang had tampered with must be the evidence of his crime!
If they could find the original footage, the police would be able to convict him.
"Alright, you go ahead. I'll start the arrest operation for Li Yuanliang now. Let's work on both fronts, striving to catch him and find evidence of his crime at the same time. With irrefutable evidence, he won't be able to deny it," Han Fei replied.
Han Fei was quite confident in Xu Mo's abilities.
Moreover, he had witnessed Xu Mo's hacking skills before. This was a tech expert who could easily hack into bank systems.
Having him investigate the tampered parts of the community surveillance footage would probably not take long.
After ending the call with Xu Mo, Han Fei immediately summoned a few of his capable assistants, preparing to lead the team himself to arrest Li Yuanliang.
In fact, Han Fei could have sent his subordinate officers to arrest Li Yuanliang.
But he didn't do that.
Mainly because Han Fei knew that Xu Mo would be very quick in checking the surveillance footage, and he didn't want to fall behind Xu Mo.
It was a matter of face!
If Xu Mo found the tampered surveillance footage first, while Li Yuanliang hadn't been arrested yet, it would be somewhat embarrassing.
To quickly apprehend Li Yuanliang, Han Fei utilized Skynet.
After inputting the name, ID number, and other information, Skynet began working, searching for Li Yuanliang in the vast network of surveillance cameras.
...
Meanwhile, after ending the call with Han Fei,
Xu Mo turned to the two police officers who had come with him to collect evidence.
"I've discovered some new leads and plan to investigate them. You two continue collecting evidence, don't worry about me."
After saying this, Xu Mo turned and left the villa.
He walked straight towards the community's security office.
At the security office, after explaining his purpose to the security guards, Xu Mo entered and began checking the surveillance footage.
Tampering with surveillance footage might work on ordinary people.
Because most people don't understand this kind of technology.
But it's not enough to fool Xu Mo.
He had plenty of methods to determine if a segment of footage had been tampered with.
"Officer, is there anything we can help you with?" one of the security guards asked.
Xu Mo: "..."
He didn't know where this habit of calling police officers "uncle" came from. Why did everyone like to call them "police uncle"? You're clearly older than me, why call me uncle!
"Has Li Yuanliang been alone in the surveillance room recently?" Xu Mo asked.
"Alone in the surveillance room..." the guard pondered for a moment. "Yes! Just today, around 6 AM this morning. I had just finished breakfast when I suddenly had a stomachache and went to the bathroom. It was about 20 minutes, during which he was alone in the surveillance room. When I came back from the bathroom, he was in a hurry to leave. I asked him where he was going, and he said he was quitting."
After a pause, the guard seemed to remember something and added,
"I just remembered, I got a stomachache after eating the breakfast he brought me! No wonder this guy suddenly became so kind as to buy me breakfast! Damn it, he must have put laxatives in it!"
No wonder Li Yuanliang killed someone, resigned, and then ran away, instead of just running away directly. So he came to tamper with the surveillance footage this morning...
"Did he leave the security office alone yesterday afternoon or evening? Like patrolling the community or something?" Xu Mo continued to ask.
The guard shook his head.
"Yesterday afternoon, I patrolled with him. I don't know about the evening, I work the day shift, I'm not on duty at night. I'll call my colleague on the night shift and ask for you."
Saying this, the guard took out his phone and made a call.
A minute later, he hung up and looked at Xu Mo.
"My colleague on the night shift told me that Li Yuanliang came to the community around midnight yesterday. He said he had dropped something in the community. Since we're all colleagues, the guard on duty last night didn't give him a hard time and let him in to look for it."
"Midnight..." Xu Mo repeated subconsciously.
Guan Yiliu's time of death was roughly between 3 AM and 4 AM.
If Li Yuanliang entered the community at midnight to poison Guan Yiliu, the timing would be about right.
Xu Mo pulled up the surveillance footage from around midnight and started watching it at high speed.
He found that from midnight to 1 AM, a full hour, there was no sign of Li Yuanliang in the footage.
This clearly contradicted what the guard said about Li Yuanliang coming to the community at midnight.
It seems the tampered footage is from this time period, Xu Mo thought to himself. The footage he was watching now was probably what Li Yuanliang had replaced it with.
Next, Xu Mo attempted to recover the original surveillance video.
Knowing which segment had been tampered with made it much easier for Xu Mo to recover the footage.
His hands flew over the computer keyboard.
In no time, he had recovered the segment of surveillance that Li Yuanliang had replaced.
The recovered footage was quite similar to what the guard had described.
Li Yuanliang arrived at the community at midnight, chatted briefly with the guard at the entrance, and was then allowed in. Notably, Li Yuanliang was carrying a bag when he entered the community.
After entering, he walked directly to the villa where the deceased Guan Yiliu lived and rang the doorbell.
He took out a cake and a rose from the bag in his hand, placed them on the ground, and quickly left.
Soon after, Guan Yiliu, hearing the doorbell, came out to open the door and found the cake and flower on the ground.
In the subsequent footage, Guan Yiliu received a phone call, then picked up the cake and flower left on the ground, closed the door, and went back inside...

grated, and just when he finally managed to get into an elite academy, he discovered that he actually had a system, and the way to earn rewards was extremely ridiculous. So for the sake of rewards, he had no choice but to start acting ridiculous as well. Su Cheng: "It's nothing but system quests after all." But later, what confused Su Cheng was that while he was already quite ridiculous, he never expected those serious characters to gradually become ridiculous too. And the way they looked at him became increasingly strange... (This synopsis doesn't do it justice, please read the full story)

We're all struggling to survive out here. I'm trying so hard, so how are they still alive?"
