Original subtitles

Mr. Qi,

the results are in.

Liao Yunsheng's dead.

Xie Yaoqi's situation is unknown.

Seems we're back to ground zero.

If Xie Yaoqi weren't dead,

tonight would

be our last chance to save her life.

Logically speaking,

all the victims

should be linked somehow.

Ye Yingying, Xie Yaoqi,

Li Shuting, and Liao Yunsheng.

Four unrelated people.

Their only common link is Liao Dong,

from the cosmetic clinic.

But we've already verified

Liao Dong's alibi for the day

of the pork shop case.

But he's the only one connected

to the case now.

Call him over and ask him.

Yunsheng had it rough.

His parents died young.

It was my mom who raised him.

But now,

how am I going to explain it to my mom?

After he came to He City,

what friends did he make?

Who was he with?

What did he do

outside the university?

Do you know?

No idea.

Yunsheng has been

introverted since childhood.

He was shy and rarely talked.

Didn't have many friends.

He didn't talk much,

even when he came to my clinic.

Do you know how your nephew

and these three girls

met each other?

Well...

I think so.

Xie was working part-time for me

and met Ye Yingying.

Xie brought this girl over.

But after they knew each other,

they seemed to get along well.

They were always

chit-chatting together.

I...

Just say what you want.

Tell us every detail

you can remember.

It will help us find

who killed your nephew.

Only when Yunsheng was on break

would I call

and tell him to come over.

However,

I felt

he was quite into Xie.

I saw him peeking at the girl

quite a couple of times.

Did they have

any further progress?

No.

And I was mocking him

for his far-fetched thoughts.

As I said,

Yunsheng was very introverted.

At most, he'd bring Xie water

or buy her a drink.

Nothing else.

What's his relationship

with the other two?

The other...

The other two weren't

that close to him.

They rarely

talked to each other.

There was only once

when all four of them

came to the clinic.

Did anything

happen that time?

Well, nothing special.

That day,

the three girls were

talking and laughing,

and Yunsheng suddenly came.

Really?

He was asking me before...

Yaoqi.

The thing he recommended

last time was really useful.

Then, that girl

never came to my clinic again.

Here's Liao Yunsheng's autopsy report.

We were all misled.

Liao Yunsheng

was the first victim.

The victim, Liao Yunsheng.

Like the first victim,

Ye Yingying,

we also found

a wound resembling a spider's mouthparts

piercing its prey on his abdomen.

And his organs also had signs of corrosion

from hydrochloric acid.

Behind his ear,

we also found a needle hole that

could have caused a venous embolism.

Whether judging from the method

or the cause of death,

the killer is the same person.

Therefore,

he was the first victim?

However,

because the body was treated

with formalin and plastic wrap,

we can't determine

the exact time of death.

But after

our further examination,

it can be roughly estimated

that Liao Yunsheng

has been dead for at least four weeks.

If what Mr. Qi said

was right before,

the crime cycle

was 13 days,

then Ye Yingying

was killed after him.

That 13-day

killing cycle

isn't accurate anymore.

According to Li Shuting,

the killer killed Xie Yaoqi beforehand.

And the time when Li Shuting was kidnapped

was also earlier.

What's the reason?

Has Su found anything new

in room 604,

where Liao Yunsheng's

body was found,

and that shed?

Room 604 belongs

to Chen Hua, Liao Yunsheng's

classmate in vet school.

Chen Hua has been living abroad.

So he let Liao Yunsheng

look after that house.

We're already running

a comparison of the fingerprints

found in room 604.

The results should be in soon.

And that shed belongs

to Zhao Si,

a nearby villager.

But he accidentally

fell off when repairing his roof

a month ago.

He's been bedridden

for over a month.

He has no idea

what had happened in the shed.

The body of the first victim,

Liao Yunsheng, was found in room 604.

The estimated time of death

was more than four weeks ago.

Around four weeks

after Liao Yunsheng died,

we found Ye Yingying's body

in a cave in Beishan.

She was the second victim.

As marked in the calendar,

Ye Yingying was killed

around August 14th.

And three days after Ye Yingying's death,

Xie Yaoqi was kidnapped.

Currently, we can't confirm

whether she's still alive.

These two are Xie Yaoqi.

Could the killer have painted

all the victims?

The fourth victim,

Li Shuting,

was rescued in an abandoned factory.

The killer fled.

Judging from the killer's pattern,

with Li Shuting,

not only was

the crime cycle

changed,

but even the location

and logic

were different.

The two scenes before

had funnel webs

made by the killer.

Why doesn't this scene have one?

If the killer

sees this place as the new nest,

Xie Yaoqi should be here.

But she doesn't.

Li Shuting claimed

the kidnapper was Liao Yunsheng.

But Liao Yunsheng was already dead.

There's no way it was him.

Then who could it be?

When Xie Yaoqi got kidnapped,

we received a call

from the pork shop's owner.

But he's dead.

Therefore,

no one could prove

Xie Yaoqi was kidnapped.

You suspect Xie Yaoqi?

If Xie Yaoqi were the killer,

things would make sense.

In that case,

Xie Yaoqi left the hair

at the pork shop

just to mislead us.

From the start,

as soon as we arrived

at the scene,

we already stepped into her trap.

She let all the leads

trace to Liao Yunsheng.

Because Liao Yunsheng had

all the characteristics of a criminal.

See?

An agricultural college student

who has access to pathogens.

His uncle, Liao Dong,

owned an unlicensed clinic.

And all the victims

were related to the clinic.

According to Li Shuting,

Xie Yaoqi and Liao Yunsheng

were in a relationship.

So Xie Yaoqi had great chances

to enter the shed

and frame Liao Yunsheng.

Yaoqi?

The point is that

Liao Yunsheng is dead now.

We'd never find him,

no matter how.

Before finding the body,

we could only assume he was the killer.

We've always thought

Xie Yaoqi was the victim.

But if she were lying,

all our inferences

and evidence

would be wrong.

The comparison results

of the other

DNA sample

from the scene are in.

Who is it?

Xie Yaoqi.

When Liao Yunsheng was killed,

Xie Yaoqi hadn't gone missing.

If Li Shuting was telling the truth

that they were in a relationship,

it wasn't strange

that her DNA appeared in room 604.

The chance of Xie Yaoqi

being the killer is even higher.

If Xie Yaoqi were the killer,

could we still believe

what Li Shuting said?

He showed me some paintings.

What paintings?

It was Yaoqi.

He painted Yaoqi.

The way Yaoqi died...

It was horrible!

Is Li Shuting

at the hospital now?

No, she said she was fine.

So I sent her home.

Let's go find her

and confront her.

One of them

must be lying.

Okay.

Okay, Ms. Zhu.

Let's go.

I dropped her downstairs.

She came up alone.

304.

Here.

Li Shuting?

Li Shuting?

Li Shuting!

Li Shuting!

Was the killer after her again?

Move aside.

Who are you looking for?

Hello, is Li Shuting here?

Who?

Li Shuting.

Who is it?

This girl.

Have you seen this girl?

Doesn't she live here?

I live here alone.

Thanks.

Han Feng!

Ms. Zhu.

It was Li Shuting.

Li Shuting

has been misleading us.

Mr. Han, Ms. Zhu.

I checked the info

Li Shuting left at the hospital.

Besides the address

you just went to,

her number

and the emergency contact

she left

were also fake.

All fake?

When did you think of that?

It just came to me.

Xiaoxi,

can you check

where Li Shuting went

after we sent her home?

I'm on it.

Su, where's Wan?

He's asking the students

at the Agricultural University.

Hey, Wan.

Ask specifically

if any student

has seen Li Shuting before.

Okay.

I first saw Li Shuting

at the entrance

of our police department.

She was about to go in.

But she didn't.

She tried to convince me that Xie Yaoqi

only went missing to avoid

her parents.

Did you see her parents?

Conservative folks from the countryside.

They couldn't accept

their daughter having

cosmetic surgery.

That's why Yaoqi

was avoiding them.

I don't think Yaoqi was missing at all.

We found the clinic's address.

Where's the clinic

she worked in?

There's a business card...

With that card,

we traced it to the clinic

and Liao Yunsheng.

If Li Shuting

were really the killer,

she must have planned

to shift all the blame

to Liao Yunsheng

from the beginning.

This way, your inference

will make sense.

Help me, please!

He said he'd kill me

after killing

Yaoqi tonight!

It's so dark here!

With the sound of machines!

Look, is that Liao Yunsheng?

That's him!

Seems like him.

Mr. Han,

a security camera

captured someone

suspicious

in a black hoodie

and holding

an empty feeding box.

Could it be Liao Yunsheng?

That also explains

why the killer changed the pattern

when it

came

to Li Shuting.

Because it was all just an act

staged by Li Shuting herself

to cover up everything she did.

That means

the crime cycle of 13 days might

still be accurate.

Xie Yaoqi is probably still alive.

So our utmost priority is

to find where Li Shuting

hid Xie Yaoqi.

The agricultural professor said

the experiment for bovine tuberculosis

and the pathogens used in the experiments

were strictly controlled.

Not everyone

had access to those.

We checked the students

who participated in the experiment.

Li Shuting wasn't there.

I believe

Li Shuting must have

something to do with this session.

Too many students chose

my elective courses.

I've only seen them once.

I can't remember them.

How about this, officer?

My TA has always been

in charge of taking attendance.

Fang.

Come over.

Hello.

Hello.

Take a look.

Do you know this student?

Looks familiar.

Seems to be one of the students

in our class.

Do you have a group photo?

Or maybe photos taken in classes?

We do.

In the first class,

I took several photos.

Look.

This was taken during the bovine

tuberculosis lab session.

Yes.

Looks like her?

But the face is covered.

This person's name?

Wang Qilong.

He answered after being called twice.

Li Shuting used a fake identity?

Yes.

Their TA confirmed that

Li Shuting might have disguised herself,

using the name

Wang Qilong.

So Liao Yunsheng met Li Shuting

at the course.

But the one he met

was her in disguise.

No wonder he had that reaction

in the cosmetic clinic.

This one, room 101.

Thank you.

Alright.

Hello, anyone?

Who are you?

Wang Qilong.

Do you know this person?

Which one is you in the photo?

This one.

Are you sure?

Yes.

At the same time,

your TA also took

a photo from the side.

Take a closer look.

Check it out.

Is this also you?

It's me.

Who's the student

next to you?

I don't remember.

You've been with them

for so many sessions,

yet you can't remember the names?

I...

I rarely talk to my classmates.

Calling you here

for questioning

means we've already got

certain evidence.

I'll ask one last time.

Who is

this person?

What's her name?

Did something

happen to Shuting?

Is she alright?

Her name's Li Shuting, right?

Why did she

show up in class

in your name?

That day,

Shuting heard I had a lab session

and felt interested,

so she wanted to go.

She never went to college.

She was curious about

everything there.

I never liked attending

lab sessions.

So I let her go for me.

Did Li Shuting know

what your lab session covered?

That was a session where we conducted

experiments separately.

I thought

no one would notice.

So I let her go

dressed as me.

That's all?

That's all.

What happened to her?

Why do you keep asking?

Do you know something?

Or did she tell you something?

Has Li Shuting gone

to classes in your name

except this once?

It was the only time.

Where is Li Shuting now?

I don't know.

What happened to her?

Answer our questions first.

I really don't know.

What happened to Shuting?

When was

the last time you saw Li Shuting?

We hadn't seen

each other for a while before that.

He cares about her.

He asked three times.

Does Li Shuting keep spiders?

Why do you ask?

This is her pet, right?

I can tell you care about her.

You must know that

she's mentally ill, right?

Does she often fantasize

that she is a spider?

We suspect she killed these two people.

Is...

Is this all Li Shuting's doing?

Yes.

She killed people?

Do you know something?

She murdered them?

Yes.

And if you

tell us about it,

we will be able

to save another life.

If you want to help her,

tell us everything you know.

I know nothing.

This guy definitely knows something.

Your face

does look pretty.

No matter how hard I try,

I'll never be like you.

You know how much I envy you?

No one likes me.

No matter how pretty I become,

no one will ever like me.

Didn't you and Ye Yingying

always call me ugly

and terrifying?

I heard everything.

Did you forget?

Back at that clinic,

when the three of us had our

beauty shots together.

Shuting, Yaoqi,

let me tell you.

This beauty injection is very effective.

Get the second shot

after three months,

and I guarantee you'll find a new self!

Yingying, there's a spider behind you!

Is it off?

There! It's over there!

This thing looks so creepy.

These scary

and hairy things

give me the creeps.

Such bad luck.

This stupid thing

ruined my day.

Spiders are so ugly.

They don't deserve to be in this world.

So filthy!

Shuting?

Don't you feel disgusted?

Didn't you say I didn't deserve

to be in this world?

Your time is almost up.

We searched their places.

Nothing was found.

Now we lost track

of Li Shuting, too.

Keep stalling like this,

and she'll kill again.

I always felt there must be

some blind spot in this case.

Blind spot?

In fact, we have no

solid knowledge of the killer.

What if we got fooled?

Neither the killer nor the victim

is who we think they are.

Just like Li Shuting,

the killer could

hide as a victim.

Victims are both male and female.

This doesn't fit a serial killer's

mindset at all.

Both male and female...

What is it?

Before, we assumed that the killer killed

not for preying,

but for reproduction.

Strangely, though,

there were no

signs of sexual assault on Ye Yingying.

However,

if Li Shuting were the killer,

finding no signs of sexual assault

would make sense.

But...

But she was supposed to kill men.

If the killer's purpose

was to reproduce,

why did she kidnap

Ye Yingying and Xie Yaoqi,

who were female just like her?

The first one she killed was Liao Yunsheng.

Killing Liao Yunsheng is to mimic

a female spider

killing a male spider.

So she treated Liao Yunsheng

as a male spider.

But after killing him,

she should have mimicked laying eggs.

Why did she do the same

to Ye Yingying and Xie Yaoqi?

Unless...

Unless she couldn't lay eggs at all.

Ye Yingying's body had

a wound on the abdomen.

Her uterus was damaged.

The killer appeared

to kill women out of hatred.

Perhaps

her purpose was to destroy

their uteri.

If she couldn't reproduce...

Ibuprofen,

Yasmin,

fluoxetine,

and estradiol valerate.

These were

the medicines in Li Shuting's bag

when I first saw her.

You were in Narcotics before.

You should know

about the medicines.

Estradiol valerate.

For women,

it helps with ovarian health

and fertility.

Some also use it

for irregular periods.

What about men?

Li Shuting has been taking

estradiol valerate.

He's not a girl at all.

You still don't get

how serious the situation is.

If you don't tell the truth now,

your life will be ruined.

Tell us everything you know.

Shuting... He...

He's not Li Shuting.

His...

His name was Li Shujun.

They don't know my beauty.

But that's alright.

Soon, they will pay the price.

Very soon.

He's Li Shujun.

I'm Wang Qilong.

We've known each other

since childhood.

We were both orphans.

Twinkle twinkle little star,

how I wonder what you are.

Flowers!

Wang Qilong, are you done yet?

Wang Qilong?

Stop running!

I'll catch you!

Isn't this that freak

Li Shujun in our class?

But Shujun wasn't a freak.

He just had bisex chromosomes,

but he was rejected,

even bullied.

That's why he ended up this way.

Shujun has always been

introverted

and shy.

But I was the opposite.

Looks pretty?

At the age of eight,

he wanted to start fresh with a new name.

Since then,

he became Li Shuting.

He said

he'd be happy that way.

Alright, kids.

What are your names?

I'm Li Shuting.

Here, let's take ID photos.

Lower your head a little bit.

Tilt to the left a bit more.

I wanted him to be happy.

I didn't want him to get bullied.

What are you doing?

Don't push me!

So what if I do?

Li Shujun?

Li Shujun!

Ma'am,

someone's fighting over there.

Hey, stop it now!

Let go!

Wang Qilong.

That's you. There you go.

What's your name?

Wang Qilong.

How old are you?

Nine.

Okay.

Your turn.

What's your name?

Li Shuting.

How old are you?

Eight.

Eight, alright.

So you kept hiding

his identity for him?

Yes.

He left our hometown

with a new identity.

No one knows us here.

We became our new selves.

Goodbye, Li Shujun.

Goodbye, Wang Qilong.

Officer,

I beg you, please.

Please tell me

what happened to Shuting.

I shouldn't have

let him go to the lab for me.

It's all my fault.

All because of me.

You can still

help him.

Just tell us

where he is now.

I just want to be pretty

like you people are.

What's wrong with that?

After meeting me at school,

he thought I was a freak.

And you looked down on me after finding out.

I saw him in the toilet at school.

He acted sneaky,

doing something.

What?

That's insane.

What a freak.

And he's been so close to us!

It feels so disgusting.

Geez, what a pervert!

Do you know that

anyone who mocks me deserves death?

Do you know

how it feels to be reaching the end of your life?

Don't you deserve death?

Don't be afraid.

It will all be over soon.

How is she?

Need detox ASAP.

Could Li Shuting's hallucination

be caused by his medicine?

You keep dwelling on it.

You still can't get over Fei's death.

You think she'd be happy with this?

How did a missing case get transferred to us?

The victim's name is Liu Yuanyuan.

Her mother died from illness a while ago.

My mom was murdered.

I'll avenge her.

These look like

human bones.

Female,

above 45 years old.

New discovery.

Human bones in three different locations.
