Su, call an ambulance.

Yes, sir.

Mr. Qi.

Here.

Mr. Han, no one here.

How is she?

Gotta detox her now.

Xiaoxi,

check on the ambulance.

I'll go check there.

Okay.

Mom.

Take a rest.

Thank you.

It's fine.

- Thank you. - Thanks.

Dad, Mom.

Don't cry, babe.

Alright. Let her rest.

It's all over now.

Right ahead.

I'm just different from others.

Does that make me a freak?

Why would they bully me?

They're all jerks.

I'll always protect you.

Will you?

Yeah.

You were never a freak!

Never...

Back when Li Yiqi was

facing off with you on the rooftop,

did he kinda react to the light?

React to the light?

What are you even guessing at here?

Before Fei died,

she had the same reaction in the car!

Stop bringing up Fei!

Can we just drop it?

I solved the Raw Diamond case in person!

The killer died on the spot!

Li Ming's dead too!

Every drug dealer connected to

that case

got locked up or shot!

Snap out of it, Qi Sizhe!

This is over!

You're the irrational one!

Just get over it, okay?

Fine!

I've said whatever I could.

Believe it or not!

Just stop it!

It's totally up to you!

You were adopted,

but Fei had always

treated you as her own brother!

I don't care what you'll do!

I don't care if you'll

investigate it!

I will find out the truth for Fei anyway!

It's over, all over!

I cracked that case!

That's over!

Get over it!

Wake up!

It's done and dusted!

It's over.

Mr. Qi.

Did you finish Li Shuting's blood test?

Not Raw Diamond you're looking for?

Come in.

Mr. Bai.

All the reports of Li Shuting's case

are here.

Thank you.

How are Qi Sizhe and Han Feng doing?

They can talk just fine at work,

but I can still feel there's

a bit of a wall between them,

probably because of

what went down before.

Give them time.

I'm leaving then.

Okay.

Mr. Qi.

Have you sorted out all the evidence in Li Shuting's case?

Yeah.

I'm gonna file it.

Are these

all the medicines seized from her home?

Yeah, some over-the-counter meds.

Here are more. Look.

I need to re-test them.

Mr. Qi, what are you trying to test?

Nothing much.

Just gotta confirm something.

Mr. Qi,

Li Shuting's drug test report is out.

She'd been taking anti-bipolar meds.

Apart from quetiapine fumarate,

nothing else special in her system.

You looking for something?

I'm wondering

if her hallucinations were

caused by the drugs.

But anti-bipolar drugs

shouldn't cause hallucinations.

Gao Yuan.

You ever seen this logo?

No.

Thank you.

It's fine.

Ms. Liu.

Here's your mom's death certificate.

Autopsy...

Autopsy!

Miss...

I request an autopsy!

Please calm down...

She didn't die of illness!

I'm sure of it!

Ms. Liu, please...

I demand an autopsy!

Please calm down...

Well.

Got anything from that drug?

No, the result's not out yet.

Why?

You're gonna look into it?

Li Shuting and Li Yiqi were

really in similar states

of hallucination.

Yes.

As long as we can prove

that there are the same

drug components in their bodies,

we can prove

the existence of a new type of drug.

Even so,

these two cases

can't be compared with

the Raw Diamond case.

Han Feng...

I know you've been stuck in this

and can't let go of Fei's death!

But if she knew

her death's holding you back,

she wouldn't...

She wouldn't be happy.

Han Feng.

That can't be what really happened to Fei.

I only trust what I saw with my own eyes!

Even if there's just a tiny bit of hope,

even if it's a one-in-a-thousand chance,

I won't give up.

The victims showed no signs of common poisons,

but they all reacted to light.

Light attraction...

Don't you move!

- I surrender! - Well?

Stop it!

Say it again.

I surrender, okay?

I got injured! It hurts!

What's wrong? It didn't kill you, huh?

Come on. You're gonna die before that.

Seems you're fine.

Congrats on your promotion, Captain Guan.

Oh, Captain Han.

Thank you for leaving, so I got the chance, huh?

You're welcome, Captain Guan.

Alright. Stop it.

I got this.

You're a guest here.

I gotta take care of you.

- Come on. - No need for that.

I'll just be straight.

I'm here 'cause I wanna ask you about Raw Diamond.

Raw Diamond?

Your colleague, Ms. Zhu, called me before.

Also for Raw Diamond. Don't you know?

So you're thinking

we never cracked that case back then?

But that's impossible.

It's Qi Sizhe.

Right?

He's now working with you.

Is it because of him?

Kind of.

Qi Sizhe speculated

that someone's working on new drugs

based on Raw Diamond

or conducting

secret experiments

on a specific group.

And these victims showed

the same phototactic reaction as Fei did before she died.

If so,

it'll be a disaster.

We'll support you anytime if needed.

The whole anti-drug squad's got your back.

Hey, I just thought of something.

We used to think

Qi Sizhe was nuts, huh?

Liu Yuanyuan...

She thinks her mom was murdered,

right?

Got it. Bye.

Zhu.

We've got a missing person case

to look into.

How come they gave us a missing person case?

The missing person is Liu Yuanyuan.

Her mother just passed away due to illness,

but she insisted

that her mother was killed.

So they suspect something's off

about her disappearance.

I've sent you the details

in your work email.

Okay.

How did you two find out

that Liu Yuanyuan was missing?

Yuanyuan worked really hard

and was never late or absent.

She'd been living frugally

as her family wasn't well-off,

and she had to look after her sick mom.

So Qing and I always brought her

some snacks or fruits

when we bought stuff.

But since that day,

I haven't seen her again.

Yuanyuan,

don't be too sad.

Your mom wouldn't wanna see you like this.

Rou,

my mom was killed.

She was murdered!

I know who did it.

I'm gonna avenge my mom.

I'm gonna get revenge.

At first, I thought

Yuanyuan was just overly sad.

Then I couldn't reach her four days ago.

I went to her place,

but she wasn't there

and her phone was off.

I got a bit worried and called the cops.

She said someone killed her mom?

Didn't she say who?

No.

She seemed so heart-broken at that time,

so I thought she was just talking nonsense

and didn't believe it.

From what you know,

what kind of person is Liu Yuanyuan?

She's pretty normal.

She seems like a really innocent and well-behaved girl.

The customers are quite satisfied with her.

She also works really hard.

But...

It's a bit of a pity.

She said

her grades were great in high school

and she was gonna go to a medical university.

Then it seems something happened

and she had to take care of her seriously ill mother.

Now she's almost 30,

not married

and even no boyfriend.

So do you know

if she has other relatives

besides her mother?

It seems she only had her mom,

so she was so sad when her mom passed away.

Then is Liu Yuanyuan's

social circle complicated apart from work?

She barely socializes.

We're pretty busy with work.

She's only

close to me and Qing.

And I've never seen her

hanging out with anyone else.

Before Liu Yuanyuan went missing,

did you notice anything unusual about her?

Oh, yeah!

After her mom passed away…

A few days ago,

I saw her using her phone to search for that thing

often used in mystery novels

to knock people out…

Ether.

Yeah!

That's it!

But I didn't think much about it at the time.

Now that you're asking me, it just occurred to me.

Was she really preparing for a murder?

Oh, stop it.

It's fine. It's nothing.

Then let's...

Let's just end here.

We'll call you if we need you.

By the way,

what we talked about today stays

between us.

They handed

this case to us

'cause they checked around

Liu Yuanyuan's neighborhood

and found out she bought a knife

before she went missing.

Ether and a knife...

What on earth was she up to?

I'm really puzzled too.

Haven't seen her for days.

Her rent is due.

So, does she usually

hang out with anyone?

She hardly goes out.

Just heads home after work,

and she'd say hi when we ran into each other.

Wan!

Xiaoxi looked up Liu Yuanyuan's phone records,

and the last power-on was 4 days ago.

I told her to check

the most recent call logs.

Before she went missing,

she called another waitress just to

ask for covering her shift that afternoon.

Seems she didn't plan to disappear for good.

She meant to come back after finishing whatever she had to do.

So why did she

buy a knife and search for ether?

Must've been planning to use it on someone else.

Someone else?

Who?

We gotta check the surveillance around here,

see where she went

after leaving here four days ago.

But this area's pretty rundown,

doubt there are any cameras around.

I'll check if she took a cab.

Just checked her home.

Liu Yuanyuan's usually thrifty,

unlikely she'd take a taxi.

Then...

I'll call Xiaoxi again

and have her

pull footage from nearby bus stops.

Okay.

Also, notify the forensics team

to collect her fingerprints

and DNA samples

from her home.

Bring back anything she's used before.

Alright.

You call forensics

and get them here.

Sure.

How is there?

Nothing wrong.

Get off work then.

Come on. The lighter.

Who's there?

What's wrong?

Someone just passed by.

How come?

It's been late.

I did see it.

You must've seen it wrong.

Let's check it out.

Hey! Right there!

Just a dog chewing on bones.

A dog?

Who threw bones here?

Be careful.

Wait, this looks like

human bones!

Come on! Get up!

Help me up!

Call the cops!

Come on! Call the police!

We were just on patrol

when we stumbled upon a bag of bones over there.

Looked like human bones.

Human bones?

You sure?

Not sure.

Mr. Han.

What did you see?

I think I spotted someone in the woods.

Man or woman?

Catch any details?

Not really.

It vanished in a flash.

Might be a woman.

Might?

Go on.

What do you say?

Female.

Based on the pubic symphysis,

the surface is rough and blurry with

a noticeable dip in the middle,

and the nodules are totally gone,

edges still spreading.

Plain English, please.

Female.

Over 45 years old.

Bore kids before.

The pelvis is intact,

no natural decay.

Doesn't look like an old corpse.

Plus, this powder

smells pungent,

like sulfuric acid.

Gotta run lab tests

to know what's really in it though.

What about Ms. Zhu and Wan?

They got a missing person case

and went looking into it.

A missing person?

Don't know the details.

Mr. Qi.

The lab results on that mystery powder are in.

Phenolic resin?

You sure about that?

Yeah, seems weird to me too.

Could you run the test again?

Sure.

Hey.

Are the ID comparison results back yet?

Can't extract

any DNA.

What do you mean?

We need more leads

to move forward on this.

Also,

the yellow powder on the bones is phenolic resin.

It's an industrial material,

biggest feature is heat resistance,

like the stuff used to bond abrasive grains

to grinding wheels.

A grinding wheel for cutting the body?

Still can't confirm that.

You should also

keep an eye out for

any related clues at the scene.

Did the drug tests for Li Yiqi

and Li Shuting come back?

Same new type of drug?

Results aren't in yet.

I'll let you know

when they are.

Got it.

Mr. Han!

No other bones found.

Expand the search area.

Yes, sir.

Searched all night

but got nothing.

That security guard said a dog gnawed on it,

but the bones don't

look chewed to me.

Should be a murder with the body chopped up,

then dissolved with acid or something to get rid of the flesh,

and dumped in the wild.

Likely just random dumping after dismemberment.

Murder and dismemberment?

Ms. Zhu,

last night we got a report about

some human bones found near a factory.

My guess is

the flesh was dissolved with acid or something,

the remains were left there.

Mr. Qi thinks

the pelvis belongs to

someone over 40.

Found anything on your end?

We're looking into

this missing young woman,

but so far we've got no leads.

But all signs point to

this young girl

being a suspect in a murder.

So Wan, are you saying

the killer might

be the girl

you're looking for?

Su, I didn't say that.

Su.

You've been a detective for a few years, right?

We detectives gotta base our words

and actions on evidence.

Be more careful with your words,

got it?

Okay, Wan.

But,

there's still a chance, yeah.

Hey!

You kidding me?

Mr. Han.

We're working on these two cases simultaneously.

Mr. Han, Ms. Zhu!

I've got new findings!

I found Liu Yuanyuan bought oxalic acid

and hydrochloric acid.

Let me tell you about

the bones we found.

For now, we can confirm

it's a female pelvis.

The woman was probably

between 46 and 49 years old,

had given birth.

The pelvis is intact,

no signs of natural erosion.

Doesn't seem to be an old corpse.

The weirdest thing is

we can't get any

valid DNA samples

from this pelvis.

We found this yellow powder

on the surface of the bones.

After testing, it's confirmed to be phenolic resin.

Although phenolic resin is a bit corrosive,

normally it should only

corrode the surface of the bones,

not completely destroy

the DNA structure.

So,

the reason why we can't

get DNA samples

is still under

further investigation.

Okay, then I'm gonna share with you

the info we've got here.

First off, we've received a missing person case.

The missing person is Liu Yuanyuan.

She left home four days ago

and never showed up.

Before she went missing,

her colleague saw her

searching for ether on her phone.

That thing often used

to knock people out in the novels...

Ether.

Yeah! That's it!

And we found out

her mother passed away from illness not long ago.

According to the hospital admission records,

her mother died suddenly

due to a sudden onset of

heart valve disease

and had a long-standing history of heart problems.

But Liu Yuanyuan insists

that her mother was murdered

and asked for a second autopsy.

After the second autopsy,

the forensic gave

the same conclusion as the first one.

But Liu Yuanyuan still insists

that her mother was killed,

and she even claims

that she knows who the killer is.

That's roughly the situation.

This is the camera footage from the supermarket near her home.

She bought bleach, gloves, black plastic bags,

and a knife

at the supermarket

near her home.

Why did she buy these things?

I heard from the clerk

that she said she was gonna clean the tea table.

Wan and I went to Liu Yuanyuan's home.

There were no signs of cleaning

anywhere in her house.

Anything else?

This is the surveillance footage

from a hardware store near her workplace.

Liu Yuanyuan bought a hemp rope,

as well as oxalic acid

and hydrochloric acid here.

Mr. Qi, these acids are...?

Powerful solvents?

Yeah.

So she bought these things to kill someone

and then dissolve the body.

Liu Yuanyuan suspects someone killed her mom,

so your guess is possible.

Mr. Han, Ms. Zhu, someone just reported

finding new bones.

Got it.

Alright.

You tell them about it.

What did you find?

Mr. Qi.

These are the evidences we found.

There's a pile of ashes here.

This looks like human bones. Look.

Put this away.

Got anything?

This time it's hands and feet.

I'm gonna confirm

if it's the same victim

as the last accident.

Did you see the person

who dumped the bones?

Who set the fire?

Okay, it's out.

What's this?

Bones?

Seems to be a hand...

A human hand!

Who?

Who!

Did you see what that person looked like?

That person was

wearing a hat.

Height...

Probably about the same as mine.

Could you tell if it was a man or a woman?

Can't tell.

But the person was very thin. Not likely a man.

Do you think it's this person?

It was really dark then.

Didn't really see clearly.

Alright.

Make a statement.

Send them back to school.

Okay.

Come with me.

You date here at midnight?

What's your major?

Mr. Han.

They didn't see the face clearly

and couldn't confirm if it was Liu Yuanyuan.

Mr. Han.

Quite similar to what Liu Yuanyuan was wearing.

Take it back for testing.

Evidence bag.

Mr. Han, Ms. Zhu! New findings!

Human bones are found in three different places!

Let's go check it out.

Alright.

Come on, hurry up.

What's up?

There... There are bones!

Human sternums and ribs were found at the landfill,

with yellow powder on them.

The pelvis was found the night before last

when the security guard was patrolling.

Parts from the humerus to the phalanges

were found in the woods.

The femur and tibia were found in a suburban lake.

Leg bones were found in the sewer on Weimingfang Road,

also with yellow phenolic resin powder on them.

It seems

these aren't the bones of one person,

but of multiple victims.

The results of the drug component

comparison in Li Yiqi and Li Shuting's bodies are out.

Mr. Wu, is it possible that the drug formula Li Ming made

got leaked?

Did it?

These bones are from multiple victims, right?

They're at least from ten people.

Liu Yuanyuan disappeared

from the surveillance at the end of an alley,

and there's a night market behind it.

Is there a chance

that Liu Yuanyuan never left the night market?

These bones

might not even be the victims'.

His goal is

to make us clueless about

where these bones came from.

The DNA of

missing persons and body parts...

We haven't compared it

for one person yet.
