Fei!

Your father's gone.

Now you're gone too.

How am I supposed to go on living?

What am I supposed to do?

It's all your fault.

All because you didn't talk her out of it.

You killed Fei!

It was you.

Such a huge deal.

Why not talk it over your mom?

If I'd told her,

she would've never agreed.

Our family already has two police officers.

You know

your dad's last wish.

You do you, and I'll do me.

I'm going into forensics.

No way.

I won't let you go.

Feng.

No.

No way!

Young people

should have their own aspirations.

Mom will understand eventually.

She's right.

The Yus are all blockheads.

Feng!

You're part of the Yu family.

Catch it!

Bye.

The killer hid the body among the specimens.

The specimen room is likely the primary scene.

If the killer committed the murder here,

then the wire fence in the back hills

could be where the killer escaped.

Any sign of her head?

Search is underway.

Someone's cleaned this.

Come on.

Give it to me.

Maybe the dismemberment took place here.

Those two rooms were connected

and later left empty.

So the left one became the specimen room.

We didn't know

someone was still using Lab 301.

Mr. Huang must have

gotten a key when they moved to the new building

and secretly kept using that lab.

What's Mr. Huang's specialty?

Neurology.

He's an old hand in anatomy,

nicknamed One-Cut Huang.

Mr. Huang...

Has he done anything

damaging to our reputation?

We're still investigating.

His office.

Mr. Huang?

Mr. Huang?

No one's here.

Could you open the door for us?

Oh, sure.

Who are you?

Why are you in my office?

Police.

Not Liu Yuanyuan's head.

And these

have been in formalin for a long time.

Mr. Qi,

Mr. Han and Ms. Zhu

are asking for the results.

The victim's head hasn't been found.

Any new findings

from the hills or the lab?

Not yet.

But they brought someone in.

Mr. Huang from Lab 301?

Yes.

Where are they?

Huang Zhengming,

where were you

last Tuesday afternoon?

What were you doing?

I don't recall.

You don't recall? Then...

What about these?

Since you've found them,

I admit it.

My mistake.

He confessed? That fast?

Then tell us

how you killed her.

Killed?

I have not killed anyone.

And the dismemberment?

These heads

were from donated cadavers.

I've never seen this girl.

I didn't kill anyone.

I mean

I used university resources for my experiments.

I'll take my academic responsibility.

Aer you saying

you just used donated remains?

Then why are there extensive signs of blood cleanup

from the specimen room to the lab?

That's not my lab.

The university halted my research.

So I found an old lab

to continue my research.

And that's it.

You know what?

Brain dissection

is incredibly delicate and precise.

How could there possibly be blood?

No way!

If a young woman's body

was dismembered

in your lab,

would there be this much blood?

I don't know that girl.

I didn't kill anyone!

Fine. Next question.

How do you usually eat

at the office?

Whatever.

Takeout, right?

Yes.

I scroll on my phone

and pick whatever I see.

This shows the dates.

From August 31st to September 15th,

you kept

ordering from Spring Cuisine.

They handle their own deliveries.

No takeout riders.

She's an employee there.

After she went missing on September 16th,

you never ordered

from that restaurant again.

How do you explain that?

Browsing on the phone is troublesome

and a waste of time.

So I pick one restaurant and stick with it.

Is there an issue?

I always had the delivery person

leave it outside the door.

I don't even know who delivered them.

Mr. Huang,

we know you're an expert in neurology,

specializing in cerebrospinal fluid neuroanatomy

and gliomas.

It takes

a lot of real dissection work

to back up any claim about how neuroanatomy

relates to disease,

right?

We've also learned

from your colleagues

that you've felt your experiments were hindered.

If you could do extensive experimentation,

you'd create medical wonders.

These are all noted in your journals.

You wanted to use Liu Yuanyuan for a live experiment,

but accidentally killed her,

so you hid her head

and dumped the body

to mislead us, right?

Yes.

For my research,

I am willing to kill.

I've imagined countless times

about dissecting a human brain to see its secrets.

Even now,

looking at you two,

I have an strong desire

to open your skulls.

I'm a doctor.

I need to find medication to halt brain aging.

For my research,

I'm willing to do anything.

But,

show me the evidence

that proves

I killed that girl!

We need to know where that skull came from.

Please cooperate fully.

Mr. Qi, I'll go back first.

Han Feng.

I've seen Li Ming

wear this watch.

And he

engraved this.

Come on.

Not everyone is connected to Raw Diamond.

Our most important task now

is to find who killed Liu Yuanyuan.

Focus on your job.

Han Feng!

Just do your job.

Something's here!

Shovel.

Open it.

Found it.

Huang's statement.

Xi is verifying it.

There are six skulls.

Some were obtained by Huang via his private contacts

at the donation center.

Others were removed

from the discarded specimens.

He didn't lie.

Mr. Han, we've got something new.

If the murder weapon is a hammer,

the killer likely has a medical background.

Maybe someone from the medical university.

Was a similar hammer

found in Huang's office?

No.

Time of death?

Based on the soil moisture in the back hills,

air temperature,

her viscera,

and the epidermis of the head,

the time of death should be

between 2 and 6 PM,

five days ago.

Hey, Xi,

now verify

Huang Zhengming's alibi.

With the current evidence,

I think

it's hard to identify Huang Zhengming as the killer.

We suspect Huang Zhengming

because we think he'd use the victim's head

for neurological research.

But aside from

the fatal blunt trauma to the right parietal bone,

the body shows no signs of dissection.

In other words,

Huang Zhengming didn't use Liu Yuanyuan's head

for brain research.

Besides,

this is

the donor list provided by Huang Zhengming.

And this is

the notebook found in Lab 301.

The handwriting in the second half

closely matches the handwriting on the list.

But look at the handwriting in the first half.

It's completely different.

Same writer?

Right.

Both belong to

Huang Zhengming.

The handwriting of Parkinson's patients

often becomes smaller.

It's called micrographia.

Involuntary hand tremors

cause irregular lines.

This fits Huang Zhengming's current symptoms.

And in Lab 301,

the skulls Huang Zhengming removed

have uneven cuts.

But Liu Yuanyuan's skull

has a clean and precise cut.

So with his condition,

he couldn't have perform such dismemberment?

Unless...

someone helped him.

Wan,

look into Huang Zhengming's medical records.

Check health insurance

and university reimbursements.

Also, check his connections.

Keep me posted in real-time.

Based on

the estimated time of death,

we've traced everyone

who entered the specimen room after that.

Liu Bingren.

Xie Qiang.

Wang Wenkai.

Huang Zhengming.

Zhang Zhiqi.

Luo Kai.

Gao Huilan.

Wu Min. Eight people in total.

We've got Huang's medical records.

He's had Parkinson's for years.

It's worsened this year.

So he seldom gives lectures now.

And his connections?

He never married,

lives alone,

and has little social interaction.

Given the existing evidence,

an accomplice

is highly improbable.

He's not a people person.

Well, let him go.

Tell him not to leave the city

and be available for questioning.

Su, go ahead.

Okay. I'm on it.

So we can

clear Huang Zhengming for the time being.

But a few points are clear.

First,

the killer has

professional knowledge and skills in dissection.

Second,

he knew the specimen room

and Huang Zhengming's Lab 301

are connected.

So he

hid the body parts in the specimens

and mopped up blood

to lead us to the lab,

framing Huang Zhengming.

I asked the building manager.

He said

the specimen room and Lab 301 were connected

over a decade ago.

Recent years, they've been separate.

Not many people know about this.

Likely from the medical university,

and they've been there

for quite some time.

Based on our discussion,

of the people who entered

the specimen room

on the day Liu Yuanyuan died,

only these three fit the profile.

Let me explain

the features of squamous cell carcinoma.

It's

most common

in people over 40.

Su.

Mr. Qi.

Heard Huang Zhengming's been cleared as a suspect.

Yes.

No evidence

ties him to the murder,

or to an accomplice.

What's wrong, Mr. Qi?

Mr. Huang!

Mr. Huang.

Mr. Huang.

Where did you

get this watch?

Do I have to explain it to you?

Do you know Li Ming?

Are you interrogating me?

Fine.

Show me the proper paperwork.

No? Then don't waste my time.

I only found

Li Ming's DNA (deoxyribonucleic acid)

in the car.

But when you were unconscious,

you saw someone.

Your intuition and your memory

are unreliable.

Qi Sizhe,

you're refusing to face reality.

You just can't convince yourself.

Listen.

Jiang City Medical University is developing a new drug.

If it succeeds,

countless lives could be saved.

Do you know what kind of patient

I dread most as a therapist?

Those who know they are asleep,

yet choose to keep dreaming.

According to the clues

we've gathered today,

Liu Bingren and Wang Wenkai

registered and collected cadavers on the morning

and afternoon

of the incident.

After collecting the cadavers,

Liu Bingren went to the lab building for class

and stayed until evening,

with students as witnesses.

Wang Wenkai attended a meeting at the admin building,

also with witnesses.

So both have alibis.

What about Gao Huilan?

Xi.

She was accompanied by a student

when she went to

collect the cadaver.

I asked that student.

Nothing seemed off.

So

all three have alibis?

Exactly.

Great. All our work was for nothing.

Xi, have you checked Liu Yuanyuan's call records

and her bank statements?

Anything odd?

There are

no unusual transactions.

And nothing suspicious

in her calls or receipts.

Seems she lived a simple life.

At the start of the case,

the store's footage,

Liu's knife, black plastic bags,

packing tape,

gloves, hydrochloric acid, bleach,

and rope.

Why did she bring those to the medical university?

We suspected

she was the killer

because she bought those.

But then she died.

Two possibilities.

First, she went to the university

to conspire with someone to commit murder.

Or second,

she went there to harm someone,

but ended up getting killed.

Where did she go

after bringing those things

into the university?

I remember her former boss mentioned

she originally wanted

to get into the medical university.

Could there be a connection

between the two?

It's a real shame.

I heard

she did very well in high school

and was supposed to attend medical university.

But something happened,

so she was caring for

her sick mother.

Something must have happened

when Liu Yuanyuan was in school.

This might be a lead.

Let's dig deeper into Liu Yuanyuan's background.

Check everyone she knew,

every school she attended,

and any grudges she held.

Besides, look into these three.

See if they're connected

to Liu Yuanyuan.

- Yes. - Okay.

This is a good school.

They say students here

never fail to get into top high schools.

Hello.

Police.

Well, please.

Thanks.

Liu Yuanyuan won so many awards.

Yes, I heard

she did well in her studies.

However,

I haven't been at this school long

and don't know much

about the school's work.

But our school

has always taken student records

very seriously.

This was

Liu Yuanyuan's homeroom teacher,

Ms. Lu.

Hello.

Hello.

Hello,

we're the police.

Have your seat.

The principal briefed you?

We're here

to ask about

Liu Yuanyuan,

a former student of yours.

Yes, he mentioned it.

Even though

Yuan graduated years ago,

I remember her clearly.

She was a student I valued highly.

A top student

aspiring to be a doctor.

I was quite confident she'd get into

the medical university.

But she missed

her first college entrance exam.

She missed it? Why?

It's said that she was seriously ill.

She repeated her senior year at our school.

But her grades weren't great.

Later I found out

she only took one exam

and left in the middle of it.

Why?

I don't know.

I tried to ask her,

but I could never reach her again.

Maybe you could ask

the invigilator from that year.

Exactly.

About the invigilator,

you can try checking with the education bureau.

Thanks.

- Thanks. - My pleasure.

Can we take this back?

Should be fine.

- Thanks. - Okay.

Mr. Han, here's Gao Huilan's info.

Take a look.

There was a student

with Gao Huilan at the time.

What did she say?

Nothing unusual.

Just standard procedure.

Why did Ms. Gao only call for you?

Why not someone else?

Are you two close?

Actually, it's because we're not close.

Not close?

What do you mean?

I kept failing my anatomy exams.

Ms. Gao had no choice,

so she gave me some tips for the retake

while we transported the cadaver.

Did you get all that?

Don't fail again.

Though I'm studying medicine,

I'm pretty scared of corpses.

Haven't gotten over it yet.

This is my second retake.

If I fail again,

I will not graduate.

Ms. Gao is nice.

She doesn't want my efforts wasted.

What happened when they went to get the cadaver?

Gao Huilan and Wu Min pushed a gurney together

and left the specimen room.

Alright, let's go check.

Hello,

do you remember this student?

She...

Yeah, I remember.

It's been years.

You still remember?

Because she looked like

a student I used to teach.

But that student

went abroad long ago.

So you had the wrong person.

I checked the exam paper,

and when I saw her name,

I realized my mistake.

Did you notice

anything unusual about her?

We heard she only took one exam

and left in the middle.

She ran out of the exam room.

No answer

when I called,

and she ran off in a panic.

What was

your student's name?

Ding Youmei.

Thank you.

Xi.

Ms. Zhu.

What's up?

I've found information

on Ding Youmei.

She's an assistant professor

at He City Medical University.

Ding Youmei is Gao Huilan's daughter.

Fei,

if only I had listened to Han Feng

and not let you become

a forensic doctor.

Cross long over short

and knot it.

That's how you make

a perfect knot.

If you don't let me do it myself,

how will I

become a good forensic doctor?

Alright, you do it.

I want to find the truth

for those who can no longer speak

and let them

rest in peace.

I believe you'll become

a great forensic doctor.

If that day

I had answered your call sooner

and found you earlier,

you wouldn't...

But don't worry.

I will find the truth

and let you rest in peace.

The one in uniform is Liu Yuanyuan.

The one with a mole between her eyebrows is Ding Youmei.

I suspect they swapped places.

Swapped places?

Did Liu Yuanyuan come to see you at the lab?

Was Ding Youmei there?

She had been hurting us all along.

This is all your fault!

I'll kill you!

Yuan's mother passed away.

I understand everything Yuan did.

We've checked all the school's cameras.

Liu Yuanyuan left the school through the main gate

after leaving the lab.

What's this?

Human tissue.

When moving a cadaver,

it's usually placed inside the bag.

It's also the best way to hide something.
