Chapter 173

Before, in slideshow mode, not a single viewer in the livestream room had noticed anything off about Li Sai Gao's eyes.

Until just now.

When Ning Chen, from a huge pile of photo screenshots, had filtered out five of them.

The viewers still hadn't noticed any problem.

But at this very moment.

But Ning Chen! After opening these five photos, arranging them in a sequence, and placing them side by side.

Everyone!

Only then discovered an astonishing detail!

These five photos.

Going from left to right in order, if we call them A, B, C, D, and E respectively.

In photo A, the direction of Li Sai Gao's gaze was lowered.

Because these photos were all screenshots taken from a video clip of him singing while playing the guitar.

So in this photo, it was obvious that his gaze should have been looking toward the guitar in his hands.

In photo B, Li Sai Gao's eyes suddenly looked forward.

But not toward the camera.

If he had been looking toward the camera, then when viewers looked at his eyes in this photo, they should have felt as though those eyes were looking right at them.

In this photo, although Li Sai Gao's eyes were looking forward.

They were looking sixty degrees to the left of straight ahead.

And after placing photos A and B together.

Only then would one notice that although the eyes in photo A were lowered, the gaze was very gentle.

While in photo B, in those eyes looking sixty degrees forward, the gaze was clearly tinged with a hint of astonishment.

Right next to it, photo C.

Presented a very terrifying look.

This kind of look would have been impossible to notice in a video clip.

But now, after being screenshot by Ning Chen and placed side by side with the other photos, the contrast suddenly became very obvious.

The gaze in this photo wasn't looking at the camera either.

Instead, it swept to the right—this gaze… carried a venomous quality, and fury!

As if he had issued a command with his eyes, and someone hadn't carried it out right away, which had provoked his wrath.

Next to photo C were photos D and E.

In photo D, Li Sai Gao's gaze was somewhat flustered.

And by the time we got to photo E beside it, those eyes had once again returned to their former simplicity and kindness, becoming much gentler—back to normal, you could say.

No one.

Could have spotted these subtle differences in gaze within such a long stretch of video.

Only Ning Chen.

Not only did he notice them, he was also able to pull out the corresponding screenshots.

He found all five photos and even arranged them in a sequence.

To pull this off was simply unimaginable.

Under normal low-quality network conditions.

One second of video is roughly 15 to 20 fps.

What on earth is fps?

It's actually very easy to understand.

One second of video content is made up of multiple photos; strung together, they form the moving picture of the video, and each photo can be called a frame.

And within that one second of video, the more photos—that is, frames—there are, the more delicate the video picture becomes.

Fps, then, is the number of frames that can be transmitted over the network in one second.

Tonight's replay of Ning Chen's livestream was saved as a high-definition video.

To keep the video smooth, the fps has to be at least 30—that is, one second of video content must contain at least 30 frames' worth of photos.

If it falls well below this standard, the video will start to lag; those laggy, glitchy moments you get while gaming are actually just lag caused by network latency.

And Ning Chen's replay video was far above this number—greater than 60 frames.

And within the livestream replay, Li Sai Gao's singing segment was at least two minutes long.

Two minutes is 120 seconds.

The total frame count for 120 seconds is 7,200!

That is, 7,200 images!

7,200 images that all look nearly identical!!

What Ning Chen just did, that whole sequence of operations, was from those 7,200 nearly identical images…

Filter out these five!

In the livestream room, the bros who didn't understand were merely marveling at how fine-grained Brother Shiguang's observation was.

But the bros who did understand were all firing off bullet comments.

Just how badass must one's insight be to have, in that not-so-very-long stretch of time just now.

Filtered out these five photos of subtly different gazes from among 7,200 images?!

This is simply monster-level insight!

And only after the streamer finished doing this.

The three million online viewers in the live room at this very moment.

At the instant they saw this arrangement and combination of the five photos, a shock instantly enveloped everyone.

These five gazes were absolutely unnatural!

A shy boy from Mianbei who had appeared so simple and sunny during the late-night live call.

Would actually, in this instant, unleash such a bizarre, suspicious gaze...

This Mianbei person!

Definitely has a problem!

At the same time.

The Donghai City Bureau.

The officers watching this live stream.

Saw this scene.

Also directly inhaled a sharp breath of cold air.

And began whispering among themselves.

"Why would this Li Sai Gao show such a gaze?"

"This gaze—based on my years of fighting criminals! I guarantee, this guy is definitely not a good person!"

"Don't speak too definitively; a gaze doesn't necessarily prove anything."

"He... just screened the video content, compared it for a while, and discovered it?"

Everyone simply found it incredible.

And among the officers, those who knew the technology in this area.

In the eyes of the police, this task would be very difficult to accomplish through human effort.

In most cases, only an artificial intelligence program might be able to detect clues.

But an AI comparison program, to detect such subtle details, might very well miss something.

And this Ning Chen.

Actually completely!

Did it just with his naked eyes, and moreover!

Only by opening the images on a computer to compare them!

In just this short while, he actually presented this result!

Simply... incredible!

Of course, some also said, "You can't say someone has a problem just by comparing a few gazes, can you?"
