Chapter 307: Xu Mo Is Boasting

There are two ways to verify which situation it is.

The first is to keep pushing forward and check earlier surveillance footage.

The second is to review the surveillance from after the incident up to now; if during that period the footage captures someone who never went onto the Rooftop but comes down from it, that person is the murderer, and you can issue a Wanted Status for him directly.

If no such person is captured.

That would indicate the murderer might truly be very patient, and is probably still perched on the rooftop.

At that point, just going to Guo Jin Building for a look would suffice.

If the murderer indeed used this method, he should still be on the rooftop, and arriving there would allow an immediate arrest.

Conversely, if the rooftop is empty, then Xu Mo guessed the murderer's method incorrectly.

Thinking this, Xu Mo began reviewing the surveillance from after the incident up to now.

This segment of footage is relatively short; the incident occurred a little after eight in the morning, and now it's ten thirty at night, a span of only a dozen or so hours.

Xu Mo spent just ten minutes to run through the surveillance captured at the stairwell from after the incident up to now.

Because everyone is rather superstitious about death, no one went onto the Rooftop in the post‑incident footage; from then until now, not a single person.

In this footage, no one went up, nor did anyone come down.

Still the same old habit, fearing he might miss something on a single pass, Xu Mo checked a second time.

He spent another ten minutes, and Xu Mo finished the second viewing.

The result was the same as the first viewing.

In this case, he has to go to Guo Jin Building to verify.

Since the hallway surveillance from after the incident to now didn't capture the murderer leaving the Rooftop, it means either the murderer is still hiding on the rooftop, unwilling to descend, or he was never on the rooftop at all, meaning Xu Mo guessed the method wrong.

Xu Mo called Han Fei back.

"No need to watch, Han Team, I've gone over the surveillance from forty‑eight hours before the incident up to now twice, and found no suspicious person. This murderer either has extreme patience, having been lying in wait for more than forty‑eight hours to kill, in which case he should still be hiding on the rooftop,"

"or I guessed his method wrong; he isn't on the rooftop at all, and I'm heading to Guo Jin Building to check."

Han Fei: "???"

"You've finished watching? You've also finished the post‑incident footage up to now??"

Han Fei was stunned; his mind just couldn't process it for a moment.

Originally, he was staring intently at the footage, daring not to blink too often lest he miss a clue, and by now his eyes were sore and his head a bit throbbing.

Even at six‑times speed, he's only gotten through twelve hours of footage, barely halfway.

Xu Mo, however, told him he'd already watched the entire surveillance from forty‑eight hours before the incident up to now, and even watched it twice!

He should know that from when he started watching until now, only about two hours have passed.

Even at six‑times speed, he can only cover twelve hours of footage.

And Xu Mo… actually finished the surveillance from forty‑eight hours before the incident up to now! And he watched it twice!

That span is at least sixty hours; watching it twice amounts to one hundred twenty hours.

Xu Mo watched one hundred twenty hours of footage in two hours? Sixty‑times speed???

So Xu Mo's viewing speed is ten times his own?

Is he even human?

"I've finished, I watched it twice, I can't be wrong," Xu Mo replied. "I'm heading to Guo Jin Building now to take a look."

…

After cutting the call,

Xu Mo went straight to Guo Jin Building.

Han Fei kept watching the footage.

Although Xu Mo said he'd watched all the footage and insisted he couldn't be mistaken,

Han Fei, however, didn't believe it.

Who could finish sixty hours of footage in two hours? And damn, watch it twice?

Sixty‑times speed… that's absurd! It sounds like Xu Mo bragging.

Bragging is one thing, but the claim is wildly outlandish!

Watching that fast is practically the same as not watching at all; even if there were a suspect, Xu Mo probably wouldn't see them!

Han Fei thinks he must rely on himself.

Xu Mo's words are so outrageous that even if you beat him to death he still wouldn't be believed; can anyone, while guaranteeing no missed details, finish that many videos in two hours?

So he completely ignored Xu Mo's claim and kept watching the footage.

…

Just as Han Fei kept watching the footage,

Xu Mo had already driven to Guo Jin Building and went straight up to the Rooftop.

After exiting the small door at the Rooftop stairwell, Xu Mo turned and glanced at the roof.

From this height, he couldn't see whether anyone was on the top.

To know if anyone was up there, he'd have to climb up and take a look.

Xu Mo stepped back a few paces, then began a running start.

When he was close, he kicked the wall hard, using that force to plant his hands on the wall ledge, his arms flexing slightly to lift his body up.

Once his eyes were above the ledge, Xu Mo saw clearly the scene on the roof above the Rooftop stairwell.

There was no one up there.

Xu Mo released his grip and jumped down.

No one up there—did I guess wrong? The murderer isn't using this method at all? Xu Mo frowned.

At the same time, he sorted it out in his mind.

He had watched all the surveillance footage from the forty‑eight hours before the incident up to now; the footage showed no murderer, and he also didn't see any hidden murderer on the Rooftop of Guojin Building.

So, that murderer never set foot on the Rooftop at any time from the forty‑eight hours before the incident until now!

If he never came, how did he kill anyone?

Xu Mo felt a little bewildered.

The murderer never contacted the victim—could he have killed from a distance?

That's unscientific…

Or… could these really be three ordinary Suicide Cases?

That can't be right; there's no way this is a suicide at all!

If others don't know, can Xu Mo still be clueless? He has a Conan‑like mind; everything he encounters is bound to have something fishy, so it's impossible to be a suicide.

While Xu Mo was puzzling, he suddenly saw a scene unfolding on the opposite building's rooftop.

A man whose face showed pain slowly walked toward the edge of the Rooftop, apparently preparing to jump…
