NINE YEARS AGO IVY BAY UNIVERSITY EXPERIMENTAL AREA

Professor Jiang.

I know you're inside.

If now's not a good time, I'll just wait outside.

Mo Yuanzhi.

How many times must I say this?

Neither your bachelor's nor master's qualifications

make you a suitable candidate for my PhD program.

Why can't you focus on basic biological research?

Why must you keep hounding me?

You're the best mentor

in gene-based therapy research.

Please give me this chance.

Thank you!

Tell me,

why study genetics?

- Because genetics can change the world. - You're lying.

Kid,

if you're gonna say you need to save someone,

listen up,

I've seen too many students like you.

Three words for you:

"It's too late."

Even after a decade on this path, you might see no light.

Just go.

Professor Jiang.

- How many times must I say-- - Professor Jiang.

I spent a long time writing this. Please take a look when you have time.

Thank you, Professor Jiang. I'll come again tomorrow.

FUTURE DIRECTIONS IN GENETIC RESEARCH, MO YUANZHI

Come in.

Stop fiddling with it.

it's due to temperature variance.

You may now apply to be my PhD student.

DINA BIRD

In South America, specifically Guatemala, there exists a bird

called the Dina bird.

It calls every 30 minutes

with precision down to the second,

earning it the nickname "bird clock."

Deep in the African rainforest, there lives a "time-telling insect"

that changes color every hour with remarkable precision.

Locally, it's known as the "insect clock."

The Great-Leaf Tree of South Africa

turns its leaves

every two hours.

While trees mark time through rings in their roots,

what we call "annual rings."

Tortoise shells record the cycle of seasons,

known as "seasonal rings."

The nautilus carves lunar rings in its shell.

Paleontologists discovered

that coral polyps secrete daily

calcium carbonate layers, tiny "growth rings",

which aggregate into

distinct annual growth bands.

By counting these growth rings

within each band,

we can determine the number of days in a year.

Remarkably, modern coral exhibits

exactly 365 growth rings.

Wait, that can't be right.

In recent years,

I've observed many anomalous cases

where coral growth rings

exceed 400 per year.

Why would this happen?

Why would this happen?

DECEMBER 12, 2024 AFTERNOON, LOOP DAY THREE

You're not like the other cops I've met.

I'm begging you…

Don't move!

Hold on just a bit longer.

What is it?

Are you waiting? For midnight?

How do you know it's midnight?

Who told you?

CAMERA ONE, INTERROGATION ROOM

What did he tell you?

Did he say everything resets

once it hits midnight?

Or that the loop starts after midnight?

Aren't you curious how he knows exactly when everything happens?

How he sees what hasn't even happened yet?

I know.

I know exactly what you two did.

And I know how you pulled it off.

Because I'm just like him.

You are…

just like him?

Who is he?

Why?

Why is all this happening today?

Fang Lu, go!

Don't look!

Move.

This is my first…

I just wanted to save her.

But that knife,

it couldn't kill anyone.

And yet…

I think I killed someone.

None of this is your fault.

Truly, it isn't.

Fang Lu.

You were just doing what any good cop would do.

All personnel,

return to the station for debriefing.

Let's get to work.

Mr. Mo.

Who's Jiang Yuwen?

DECEMBER 12, 2024 NIGHT, LOOP DAY THREE

In each loop day,

if no loop-aware person remains

to alter others' actions,

the day resets

to its original course.

But this day which has been constantly changing since midnight,

can it ever truly return to what it was?

Ding Qi,

Chief is expecting you in your office.

Sure.

Sarge.

I'm sorry.

What happened?

Fu Jun, the takeout runner you put Gu Song on,

is dead.

The company keeps harping on

about "cost-cutting and efficiency."

I'm under pressure!

Besides,

it's not even a big deal.

You really wrote to Mr. Mo?

Why does she claim I wrote a letter?

Who actually wrote it?

- Oh no! - Hurry up!

Was there an incident?

Bro?

Are you okay?

I'm in hell!

- What do we do now? - Don't just stand there!

- Call an ambulance now! - Right.

Call an ambulance.

We've reviewed the surveillance footage

and can essentially rule out foul play.

The traffic police have wrapped up their investigation.

His wife, Sun Hong,

is currently pregnant.

Got it.

Focus on your work.

Why?

Why must Fu Jun die?

He's just an ordinary person.

All he did was lose his temper in the first loop.

Why does his fate

grow more extreme each time I try to help him?

You wanted me?

- What makes you "just like him"? - Dead tired.

Between smoke bombs and a hostage crisis,

no time to eat.

You were inside.

You knew their intentions. How did you know that?

I didn't know. Was just asking.

- You didn't know? - I didn't know.

Then why wait until midnight?

Midnight? Still got hours till then.

What's up?

Then what does "loop" mean?

What does "loop" mean?

Last time I said I had special abilities,

you called it bullshit.

Now I say it again, and he buys it.

That's how we flushed out his confession,

proved he's got someone behind him.

I didn't know that?

If I'd known you were aware of it, I wouldn't have asked like that.

Bullshit?

We can figure it out quickly. Let's talk tomorrow.

"Talk tomorrow"?

Feels like I've heard that excuse

from you way too many times.

No way. I would never say that.

- Are you sure? - Dead sure.

Think it through carefully.

Haven't even eaten yet, and I gotta go interrogate the suspect.

What kind of questions are these?

You never said that?

Hello.

Sarge.

Duan Zheng just ordered me

to cut you off from all Ye Kun intel.

What the hell's going on?

I… I don't know either.

Just keep investigating.

MEETING ROOM, CRIMINAL INVESTIGATION BUREAU

- How'd it go? - We just finished.

That teacher's eyes,

they don't belong to a killer.

His movements

were pathological,

likely pre-epileptic symptoms.

He never intended to kill.

But as police, we have no choice.

We can't gamble with hostages' lives.

I've got a question for you,

not an official inquiry.

Since you also graduated from Ivy Bay University's Biology Department,

do you know about the relationship between Jiang Yuwen and Mo Yuanzhi?

I've heard some rumors.

Before his disappearance,

Jiang Yuwen held some standing

in the field of genetic biology.

I've read many of his papers myself.

There were certain differences in their perspectives and methodologies

between him and Mo Yuanzhi.

In academic circles,

the prevailing theory about his disappearance

was suicide.

Though no body was ever found.

The lab fire, it's believed he set it himself

to destroy his experimental data.

Well…

one more thing.

Why did you attend the Zhao family wedding?

The company required all top brass to attend.

As Chief Assistant,

I'm practically half-top brass anyway.

After everything that's happened today,

I guess… there's no need to go now.

One last thing.

Look at this man again carefully.

Do you recognize him?

The guy you arrested today?

Don't know him.

Though he does look vaguely familiar.

Where?

Maybe I haven't seen him before.

Never mind.

You still haven't answered any of my questions.

Which one?

How did you know there

would be an accident on Highway One this morning?

I didn't know.

- You didn't know? - I didn't know.

If you didn't know, why were you so insistent about rerouting?

Tell the driver to reroute.

Exit early at M16.

Driver, please exit at the next interchange.

It'll add a lot of extra miles.

Change the route immediately!

Because I… I saw the morning news,

checked the traffic reports.

And mainly, I've got this cop friend

who tipped me off about an accident ahead.

So I figured…

figured that route might be dangerous.

Call it

professional instinct, I guess.

You're so busy. Why do you even care about traffic?

Because…

you were on the road.

How did you know I was on the road?

Sorry. Repeat it.

Got it. On my way. Wait for me.

Sure.

Okay.

Okay.

Officer Ding,

am I free to go?

Everything You Yuxiang said is false. You're welcome to investigate.

We'll investigate thoroughly, of course.

But first, we want

to hear your version.

This You Yuxiang, he went to extreme lengths

to reopen Jiang Yuwen's case.

Why is he so convinced

you're the killer?

Why does he think that? You should ask him,

not me, because I'd like to know too.

Moreover,

Professor You Yuxiang's mental state has always been unstable.

Everyone at Ivy Bay University knows this.

Shouldn't you verify his psychological condition

before taking his word for anything?

We'll pursue all leads,

Mr. Mo.

But we still need your account of

your relationship with Jiang Yuwen.

Your cooperation is appreciated.

Jiang Yuwen

was my doctoral mentor,

and once, my idol.

By my final year,

he treated me as a collaborator,

not just a student.

For that, I'll always be grateful.

Yet I could never fully grasp

his eccentricity.

Thank you, Professor Jiang.

To everyone else,

Jiang Yuwen was "that odd genius."

So

when I chose him as my mentor,

the entire department warned me against it.

I didn't care.

In science,

which truly great mind isn't a little strange?

I admired him.

I wanted to learn from him,

to become as brilliant as he was.

I just never imagined…

our relationship would turn out the way it did.

Professor Jiang.

Here.

I've contacted an academic journal.

They've cleared peer review

and it's now with the editor-in-chief.

They called our findings "groundbreaking."

I'd be honored to publish this jointly with you.

THESIS TITLE: RAN GENE IN MALIGNANT ONCOLOGY ONCOGENESIS:

CLINICAL VALUE AS A POTENTIAL BIOMARKER

Go out.

I know.

Professor Jiang.

Professor Jiang.

Professor Jiang, why?

You're clever,

but your cleverness will be your downfall.

There are

no shortcuts in science.

Obsess over your so-called "cheat codes,"

and they'll trip you up

sooner or later.

In that moment,

I knew with absolute certainty:

My idol was jealous of me.

Qi.

If the day comes

when someone you admire envies you,

that's the only proof

you've truly succeeded.

Later, I applied to change the mentor.

But before it was approved, the incident happened.

Even the police never found Jiang Yuwen's body.

He just vanished.

I won't say more.

Investigate yourselves.

It's not like you'd believe me anyway.

Look,

I only attended a few of

Professor You Yuxiang's classes at Ivy Bay University.

We were hardly acquainted.

No conflicts, no financial ties.

More importantly,

on the day of Jiang Yuwen's incident,

the timeline, witness accounts, and lab surveillance footage

all confirm one thing:

I never entered that laboratory.

Professor You Yuxiang is still pushing these baseless accusations.

Why? What's his endgame?

And he claims

I killed Jiang Yuwen, right?

Then where's Jiang's body?

First, we'd need to prove Jiang Yuwen is actually dead.

Qi, we've wasted enough time today.

May I leave now?

I'll have someone escort you.

Later, the police and fire department arrived.

They ruled the fire as accidental.

The real victims were those students.

All their experimental data went up in flames.

Much research had to be started over from scratch.

Does that include Mo Yuanzhi?

Of course. But he was clever,

just switched research topics

and graduated smoothly.

More than that, he thrived.

That new direction eventually became the foundation of Moma.

So Jiang Yuwen just vanished into thin air?

Later, rumors claimed he drowned himself.

Only then did we learn he'd been battling depression.

What's…

what's gotten into Professor You today?

This isn't like him!

He just murdered someone in public, a female student!

Our reputation is ruined.

The entire Ivy Bay University's prestige

just went up in flames because of him.

Hold on.

Do you still have the records from that lab fire?

Any reports, backups?

We handed everything over to the police.

But I've got photocopies, want them?

Show me.

ZHAO FAMILY WEDDING IN THE EVENING CANCELED

Jiang Yuwen's disappearance from eight years ago.

That wasn't a missing person case. It was murder!

And the killer is Mo Yuanzhi.

Why does he think that? You should ask him,

not me, because I'd like to know too.

Officer Ding, I'll stop here.

Go straight to the end, turn right.

You'll see Dr. An.

This area's off-limits to visitors.

Let's talk outside.

C1 R&D CENTER, CHIEF OF SECURITY: MO YUANZHI

Peishan,

pull up the surveillance footage from Moma R&D.

If there's any fallout,

I'll take responsibility.

But every time he checks someone out,

they really end up being sketchy.

It's bizarre.

Whatever. If he wants it done, I'll do it.

Come in.

Are you okay?

Much better. We've identified

a wounded female at the auditorium scene.

She claimed to be an Ivy Bay University student,

but verification proved otherwise.

Are you okay?

I'm okay.

What's in your bag?

Open your bag!

Open it!

We found surveillance gear in her bag.

Here's what she recorded.

And her phone.

NEW MESSAGE FROM AN UNKNOWN NUMBER. PLEASE CHECK IT.

THERE'S BEEN A HOMICIDE AT IVY BAY UNIVERSITY THIS AFTERNOON. ARE YOU OKAY?

THERE'S BEEN A HOMICIDE AT IVY BAY UNIVERSITY THIS AFTERNOON. ARE YOU OKAY?

HUANG YUAN CALLING

- Hello, Chief. - Peishan.

How's your coordination with them going?

Pretty smoothly.

Has Ding Qi been acting unusually?

No,

I haven't noticed

anything unusual about Ding Qi.

How's he doing?

He's been working relentlessly.

Keep a close eye on him. Report anything unusual immediately.

Okay.

A1 RESTRICTED AREA

Why haven't you replied to my messages?

Officer Ding.

What exactly do you suspect me of?

I suspect you want to kill Mo Yuanzhi.

All I did was hire someone to take photos.

How does that make me a murderer?

What about Han Song and Tang Shaorong?

What do they have to do with me?

Your private investigator admitted

you surveilled both of them the same way.

Why?

Their deaths were ruled accidental

by your own police department.

My question is: Why were you surveilling them?

I admit

I surveilled them.

Over these past few years,

working alongside Mo Yuanzhi,

they've gradually eroded a significant portion of the Yu family's shares.

These three men

wear the masks of scientists,

but in truth, each one is a black-hearted businessman.

Of course, I can't control what they specifically did.

But if they've harmed the Yu family's interests,

that's absolutely unacceptable.

Then what did you uncover?

I discovered tensions among all three of them.

Tensions?

In a way, it was beneficial.

The best way

to maintain basic fairness in a company is through checks and balances.

But I never imagined both of them

would die within a month.

So their deaths…

what's your take?

With the balance gone,

aren't you suspicious of Mo Yuanzhi?

Of course I suspect him.

In the early morning of the day Han Song and Tang Shaorong died,

Mo Yuanzhi did something bizarre.

In the middle of the night,

he did the same thing again.

So I decided to tail him.

BUILDING TWO, UNIT 101

But I didn't expect him…

to head for Moma.

MOMABIOTECHNOLOGY R&D CENTER

B1 RESTRICTED AREA

I don't know what he's been doing

on all those late-night outings.

Meeting An Lan, perhaps?

I'm not sure.

So Officer Ding,

if you find anything,

you have to tell me.

You suspect I want to kill Mo Yuanzhi?

Right.

I want to kill him.

Ever heard that saying?

"Every married couple

has moments

when they want to murder each other."
