[Mysterious Lotus Casebook]

[Episode 6]

It's really troublesome to travel at night.

Mosquito bites have turned our faces swollen.

Mount Pufu has always had a tradition of moonlight weddings.

Besides,

it's not sunny

and you get paid extra.

It's great.

You're right.

What is that?

Run!

Granny Tian, what’s wrong?

I heard something strange happened in Mount Puchu.

Seven headless corpses are strange indeed.

Biqiu has sent people to investigate it.

There should be news soon.

Fang Duobing is nearby.

He will get himself involved too.

Let's just wait for news.

By the way,

the case in Yu City

coincided with Di Feisheng's appearance.

I heard from Shishui

there was another person.

Li Lianhua.

Have you checked his background?

Li Lianhua.

Age and background

are unknown.

Owns a mysterious Lotus Tower.

Has miraculous medical skills.

He was very helpful in solving

the Yu City case.

But this person is weak and timid,

and likes to live alone.

There are no shortage of physicians in the martial arts world.

It's not strange.

[Tomb of late husband, Qi Mushan]

Old Man.

The view here is nice and the air is fresh.

It's a good place.

But every time I climb up the mountain,

I'm really tired.

Do you know

I came here today

to give you a message?

Over the past ten years,

I've been looking for Senior,

but I couldn't find him.

Now,

I've found that Di Feisheng is still alive.

If I follow him,

I will definitely find Senior.

I'll bring him back.

One of us will be buried on your left,

and the other on your right.

Just like when we were little,

we will keep you company.

When we were young,

you often taught me and Senior to take care of each other.

I was unfilial.

I failed.

I'm too ashamed to see you.

But

other than here,

where else can I go?

Old Man,

When I find Senior,

we won't go anywhere.

I'll be your obedient disciple.

I won't be as naughty as I was when I was young.

I'll listen to you.

I won't make you angry.

By the way,

I want to tell you something else.

Senior has a nephew.

He should be his only family.

This brat is talented.

He's indeed like I was back then,

reckless

and arrogant.

He's also a piece of work.

Luckily, I escaped fast.

It's better to be free.

Right?

[Wonderful hands can cure all illnesses]

My friend.

Come here.

What is it?

You've been taking medicine for days, but you haven't recovered.

It's a bad omen.

How did you know?

Because you are possessed,

not sick.

You're just a balms peddler.

You know how to exorcise evil spirits?

What's so strange about a master hiding among the crowd?

It's you

who's got something dirty on your hands.

For example, the belongings of the dead.

You...

When you wake up in the morning,

your hands and feet are cold

you have abdominal pain.

Your forehead is dark

and your eyes are bloodshot.

This is a sign of an evil spirit possessing the body.

If you go on like this,

within seven days...

Forget it.

I won't say anymore.

It depends on whether you want to live.

Of course I want to live.

Physician—

No,

Immortal.

Save me!

Save me.

I can save you.

I need to know the cause of your possession.

Tell me what happened in detail.

Recently,

I helped my neighbor, Niu,

pawn a golden item.

Since then, my body...

Where did you get that golden item.

Where did you get it?

If you don't tell me,

the evil spirit will not leave.

I'll tell you.

A few days ago,

seven headless corpses suddenly appeared on the mountain.

They were all covered with gold, silver, and silks.

My golden items

came from those seven headless corpses.

The pawnshop owner said

those were Prince Fangji Mansion's treasures

from 100 years ago.

Physician, I told you everything.

You must save me.

I see.

It's easy to cure.

This looks like a balm,

but it's actually a talisman.

Stick it on your belly button.

Close your windows at night.

You'll recover tomorrow morning.

Physician,

was I possessed or did I catch a cold?

Both.

Go ahead.

It's free.

Thank you, Physician.

Prince Fangji?

Mount Puchu?

Baskets for sale.

Only two left.

Take care.

Baskets for sale.

Excuse me.

It's not far from Mount Puchu, right?

It's not far.

Can you show me the way?

Turn east at the town exit.

Find it yourself.

I'm busy.

Supernumerary Yu is giving out porridge.

It'll be gone if you're late.

Baskets for sale.

We're giving out porridge.

Here you are.

Thank you.

Slow down.

Sister.

Can I have a bun?

Hello, Sir.

This porridge is for the starving.

Your clothes are of high quality.

You're from a rich family.

Why do you want porridge from here?

Go away.

This...

Here, this is for you.

Next.

Enemies are bound to meet.

Isn't this the person

who likes to ditch people?

What a coincidence.

It's fate.

What fate?

We're having bad luck as soon as we met.

-Bye.
-Wait.

You can leave.

If you don't want to travel with me,

I won't force you.

After all, we're friends.

But we need to have a farewell dinner.

It's your treat.

W-Why?

Because I'm hungry.

I'm hungry too.

Yes.

It's Yipin Tomb.

Yes.

I remember now.

It's called Yipin Tomb.

Have we met before?

Yes.

Are you talking about the strange case at Mount Puchu?

Yes.

It's Mount Puchu.

Several days ago,

seven headless corpses appeared in the mountain.

The constable said the people who saw said they were still moving.

They were all grave robbers.

They wanted to rob

Yipin Tomb.

That's why they died.

Yipin Tomb is strange.

Let me show you something.

This is the evidence

the magistrate's office got from the corpses.

The half skull is the insignia

of the Fourteen Thieves of the Netherworld.

This is the grave robbers' badge.

I heard the leader of the Fourteen Thieves of the Netherworld

disappeared ten years ago.

Seven headless corpses suddenly appeared

holding Prince Fangji's treasures

and carrying the grave robbers' badge.

Do you think

they were the Fourteen Thieves of the Netherworld?

Also,

I heard that this has something to do with

the legendary Yipin Tomb.

It’s pretty interesting.

I can cast aside our former grievances and bring you along with me

to investigate this case of the seven thieves‘ corpses.

However...

Young Hero Fang,

you’re talking on your own again.

When did I say I want to investigate the case with you?

You...

Besides,

I don't understand

a single word

of what you said.

It made me sleepy.

We'd better not see each other again.

Fine.

I don't need you to investigate the case.

Take care.

Buddy.

Let me ask you.

Is there a black market selling antiques nearby?

Antiques?

Yes.

In the mountain.

It's called Wei's Manor.

Thank you.

I'm here to investigate.

What are you doing here?

I'm here

to sell something.

To sell something?

Selling something in a black market in the mountains?

Are you selling Fox Spirit?

You said Yingzhu Armor is very valuable.

I'm here

to ask about the price.

Maybe I can sell it at a good price

and my Lotus Tower

can be renovated.

Yingzhu Armor is the martial arts world's great treasure.

You want to sell it to renovate your shabby building?

You...

Forget it.

I said I won't bother with you.

[Wei Manor]

This is private property.

It's off limits to unauthorized personnel.

I'm here to do business.

According to our rules,

you need to pay 100 taels of deposit to do business.

100 taels?

Don't tell me you didn't bring money with you to do business?

When one does business out in the world,

they need friends everywhere.

I'll pay his deposit.

Look.

We're together.

I can't just watch you get kicked out, right?

At least you have a conscience.

Take it.

This piece of hetian jade

is enough for our deposit, right?

Let's go.

Please.

You've gone too far.

How could you use my jade pendant

to pay your deposit?

Think about it.

This jade pendant is the only valuable thing on you.

You had to hand it over anyway.

Since you paid, I won't have to.

It's more worth it for both of us to come in.

Right?

You have a point.

Forget it.

I'll spare you this time.

Don't let me see you again.

This way, please.

Qiutuo.

Who do you think you are?

How dare you eat with us?

[Zhang Qingshi, Zhang Qinghu]

Z-Zhang Qingshi.

[Qiu Tuo]

Why are you glaring at me?

Wei's is having a banquet.

Everyone has a share.

I don't think you deserve it.

[Duan Hai]

Brother Qingshi.

We are guests.

Let’s not argue with him.

Give Master Wei some face.

Brother.

Duan Hai is right.

Forget it.

[Ding Yuanzi]

You look unfamiliar.

Are you here for the banquet too?

Yes.

Let me ask

when did you set off

and which road did you take?

The day before yesterday.

I took the official road.

Bamboo whistle and panpipes both make music.

This friend

is listening to music with us.

We're all in the same boat.

Everyone,

this young man

is a meathead.

He doesn't usually come out,

so he doesn't know our code.

Please forgive him.

What meathead?

How ominous.

Since when were meatheads allowed to the banquet?

When did you set off

and which road did you take?

I left at 20th watch

and I took

a solo road.

You're a veteran.

Since you took a solo road,

may I ask if you carried a flag,

and how many words were on it?

I carried a golden flag.

The four words left on the tower of the imperial mausoleum

in the south of the capital 13 years ago.

Greetings, Scholar Sushou.

Sir.

I didn't expect you to be here.

I am Ding Yuanzi

of the Gilded Gold Sect.

I am Duan Hai

of the Remnant Ink Sect.

I am Ge Pan

[Ge Pan]

of the Mountain Mortise Sect.

We are the brothers

Zhang Qingshi and Zhang Qinghu

of the Heavenly Clock Sect.

I've long heard your name, Sir.

Gu Fengxin!

Sir Sushou took the solo road

like you.

Come and pay your respects.

I'm not interested.

Sir, please forgive him.

Gu entered into this trade halfway.

He doesn't know the rules.

Please forgive him.

It's okay.

I'm here for the banquet, not to socialize.

Please make yourselves at home.

What did you mean just now?

It was code.

It's grave robbers' code.

You've followed me all the way here.

You should know where this is.

Of course I know.

The outer courtyard of Wei Manor is a black market for antiques.

The inner courtyard is a gathering point for grave robbers.

Someone discovered the tomb and came here to gather a team

to go down the tomb together.

I just don't understand

why they suddenly attacked me.

That's because you said something wrong.

The time you set off

is the number of years you've been in the trade.

The road you took

is the sect you're from.

The Heavenly Clock

[Heavenly Clock]

[Crimson Phoenix, Green Dragon, White Tiger, Black Tortoise]

observes the sky to look for openings.

The Mountain Mortise looks for tombs based on the terrain.

[Mountain Mortise]

The Remnant Ink references ancient scrolls.

[Remnant ink]

The Gilded Gold uses burial goods that have surfaced as clues.

[Meijin]

As for the Bronze Pan, Fire Money, they're all small sects.

You didn't mention any of these

and instead said that you took the official road.

The official road means the magistrate's office,

which is their enemy.

Of course they'll have to kill you.

What does the solo road mean?

It means I entered the trade halfway

without an affiliation to any sect.

These people enter the tomb with their skills

and are often killers.

So when they asked if you carried a flag,

it's to ask if you have killed anyone.

You're smart.

A gold flag means I'm a wanted criminal.

In that case,

they wouldn't dare to provoke us.

Thirteen years ago, the imperial mausoleum in the south of the capital was robbed.

23 guards were killed.

The arrogant robber left his name, Scholar Sushou,

in front of the tower.

His Majesty was furious.

He ordered the criminal's arrest, but he hasn't been found.

You're pretending to be Scholar Sushou?

You're familiar with

the imperial court's files.

That's right.

So I pretended to be a famous person

to sneak in.

You said you're here for the black market but you came to the inner courtyard.

You're also so fluent in grave robbers' code.

More importantly,

the case of Scholar Sushou is a secret order from the imperial court.

You know it too?

Li Lianhua.

There must be something wrong with you.

Don't point at me.

It's rude.

Do you know why

they haven't found Scholar Sushou?

Why?

Because he died.

I buried him myself.

He was badly injured.

I pitied him,

so I allowed him to stay with me

until he passed away.

So

in order to thank me,

he taught me grave robbers' code.

Aren't you familiar with the imperial court's files?

You should know that

Scholar Sushou's name is Qi Zhiyuan

and he has a birthmark on his forehead.

Right?

Then why did you come to the inner courtyard?

Because someone was stupid.

Who are you talking about?

Because you're oblivious

and I was afraid you would be exposed.

As expected,

you were outed as a meathead and almost got yourself killed.

Think about it.

I got confused again.

What is a meathead?

Some people rob graves,

meathead rob corpses.

They even take corpses hostage for a ransom.

They're small fry.

Understand?

Since it's dangerous

and you're here,

let's work together again.

One more time.

You're calculating.

No need.

I'm quite safe

posing as Scholar Sushou.

You were angry at me for leaving you behind

and borrowing your jade pendant.

You told me to stay away from you.

I think you're right.

It makes sense.

You don't know martial arts.

If you are in danger,

I can protect you.

Thank you.

No need.

Goodbye.

I think the Zhang Brothers

are related to the seven thieves' corpses case.

I just saw the Fourteen Thieves of the Netherworld's insignia

on their badge.

What does that have to do with me?

You can use your status

to help me.

Besides,

we came in together.

If I get caught,

you won't be able to escape either.

Fine.

You're ungrateful.

That's right.

Li Lianhua.

Do you agree?

I only guarantee your identity won't be revealed.

The investigation has nothing to do with me.

Deal.

Thank you all for gathering at my manor.

[Wei Manor]

I am very honored.

I've long heard of Scholar Sushou's reputation.

I'm the Master of this Manor.

I am very honored

[Master Wei]

that you are attending my banquet.

I've just been idle for a long time

and am looking to earn some money.

You came at the right time.

Everyone,

I have a treasure.

Please give me a hand.

Penglai Jade Mountain Vase?

This is one of Prince Fangji's burial goods.

You should know

why I invited you here.

Master Wei’s banquet is indeed

because of Yipin Tomb.

You must have heard about

the case of Mount Puchu's headless corpses.

You came here after hearing the news.

I will make sure you have a good time.

Prince Fangji

was the eldest son of Emperor Xicheng 100 years ago,

His Majesty's granduncle.

He was the Crown Prince

but got into trouble and was ordered to commit suicide by Emperor Xicheng.

That's how the throne got passed to

His Majesty's grandfather, a member of the royal family.

His tomb is called Xi Mausoleum,

and in it are extraordinary treasures.

The martial arts world calls it Yipin Tomb.

Prince Fangji had many martial arts world contacts.

Rumour has it that there are many martial arts treasures,

brilliant weapons, and martial arts mental factors in the tomb.

Over the past hundred years, countless people have been searching for it.

But all have failed.

The tomb seemed to have disappeared.

Do you know why Yipin Tomb disappeared?

It had something to do with the reason Prince Fangji was ordered to commit suicide.

Back then, the Nanyin Kingdom hadn't been annihilated.

They sent a princess to our kingdom for a marriage alliance.

She married Crown Prince Fangji as his consort.

Prince Fangji was so enamored by her that

he wanted to force his father to abdicate.

Emperor Xicheng was terribly sad and angry

so he ordered them to commit suicide,

and forbade them from being buried in the imperial tomb.

Nanyin craftsmen were ordered to build their tomb.

Yipin Tomb was built in the Nanyin style.

Nanyin was known for its strange and evil magic,

so it's no wonder no one could find the tomb using the Central Plains' techniques

for over a hundred years.

But now, we're going to find it.

The seven headless bodies on Mount Puchu

had not only the treasures Prince Fangji was buried with,

but also

a map of Yipin Tomb.

I didn’t expect that so many years after Wei Manor was established,

Yipin Tomb would show up at my doorstep.

It’s a blessing from the Heavens.

I invited you here

to make a fortune.

Master Wei,

those seven corpses came out with treasures.

That means they'd entered the tomb.

But why did they die in the wild?

Why did they lose their heads?

Yipin Tomb was built with Nanyin's techniques.

Their traps were strange and powerful.

My guess is

they were beheaded in the tomb.

Their bodies were then flushed out of the tomb

by the heavy rain.

We got lucky.

Everyone here is a master.

We won't repeat their mistake.

If anyone is afraid,

you can leave now.

What do you think?

Everyone,

what do you think?

I'm not afraid of making money.

Let's do something big together.

Good.

I've prepared a banquet

to welcome you.

Come with me.

Let's go.

Brother.

The Weeping Guanyin we're looking for

is in Yipin Tomb.

What should we do?

No matter what, we must find it.

Let's enter the tomb with them first.

Then,

we'll kill them all.

[Wei Manor, Yipin Tomb]

[Lotus Tower]

Master Wei, the banquet is at Canglu Garden today?

I heard that your Canglu Garden is very auspicious.

Holding the banquet here

is sure to guarantee success.

Everyone,

may we make a fortune.

Great!

Where did you come from?

You want to die?

Guys,

don't fight.

This is my distant elder.

Although he's young,

he is very senior.

Please be seated.

Master Wei.

Why are all sorts of things

at your banquet?

A cowardly Qiutuo

and a meathead are fine.

Now, there's even a rude little turtle.

I've always paid my crew

according to their contribution.

Yipin Tomb is no exception.

If when the time comes,

this young elder of mine is useless,

he won't get paid.

Don't worry.

Here.

Don't ruin the mood.

Let's have a drink.

This wine is good.

Good wine.

Come.

Brother Gu.

Long time no see.

I was worried

when you first entered the trade

that the disciples of the Dunjia Sect would want to make a fortune too.

After that, you joined the trade with your sister.

I finally

felt relieved

and at ease.

What is real in life?

Gold!

Here.

Let's drink.

Good wine.

Kid,

Master Wei insisted on taking you with him.

Tell me.

What can you do?

In our business,

if you follow us,

you can't just eat.

Come on.

Have a drink.

You're real man when you have some hair.

Get lost.

My hand!

Come on.

Take Ding Yuanzi to get bandaged.

Be careful.

Bastard!

I'll teach you a lesson on the behalf of your Master!

Hold on.

Brother Qingshi.

Calm down for good luck.

Sir Sushou.

What do you mean?

It's not a good sign

to start fighting before the job.

Young man,

why did you do that?

We're here to make money.

Harmony brings wealth.

Harmony brings wealth, right?

Zhang Brothers,

I know you don't like it.

But my young elder has unique martial arts skills.

Only he can open the entrance to Yipin Tomb.

Even I have to put up with him.

Just bear with it.

How about this?

Let's hold another banquet at the pond outside the courtyard.

The Zhang Brothers and I will enjoy the moon

while drinking to our hearts' content.

I have a few vats of Xifenglie on my Manor

that have been ageing for ten years.

I know you like strong wine.

Don't miss it.

Everyone.

Let's go together.

Didn't he say there's going to be another banquet?

You're leaving already?

I'm sleepy.

At the banquet just now,

you suddenly hinted to me not to drink.

Why?

I just don't like drinking.

Forget it.

Since you were kind to that kid,

I'll let it slide.

If that kid

really got hit by Zhang Qingshi,

he'll die.

Yes.

If he hit him,

he'll die.

If the headless corpse case

can really lead to the Yipin Tomb that disappeared a hundred years ago,

it will surely astound the world

and give the Master of Baichuan Court a good shock.

You're really not interested in investigating the case with me?

Aren't you sleepy?

What are you waiting for?

Eight for you and nine for me.

What does that mean?

The bedrooms.

Master Wei loves gambling.

He used dices for room numbers.

Alright.

Go to sleep.

I have something to do.

Where are you going?

The Zhang Brothers have

the badge of the Fourteen Thieves.

I also heard them say they want to kill

all the people who're going to enter Yipin Tomb.

So I suspect the seven thieves' corpses case

is related to them.

I'll go see them.

I'll be off.

[Wei Manor]

Brother!

Zhang Qingshi is dead.

His head is gone,

just like the seven corpses down the mountain.

Zhang Qinghu.

What happened?

I didn't see anything.

I don't know.

You two slept in the same room.

How could you not see the murderer?

Did someone sneak in

when you left the room?

Impossible.

I just got up to pass urine,

right at the door.

I would know if anyone came in.

But I don't know why

when I turned around,

my brother became like this.

The window is locked from inside.

You can't kill and decapitate someone in such a short time.

Plus, the other brother was here all along

didn't notice anything.

What kind of martial arts master could have done this?

Maybe it wasn't martial arts,

but sorcery.

I heard

Yipin Tomb is protected by sorcery.

Anyone who has designs on it

will be killed by socery.

The seven corpses at the foot of the mountain

lost their heads like this.

Zhang Qingshi is the same now.

Will it...

Will it be our turn next?

This sorcery is very generous.

Sir.

What do you mean?

If it were really sorcery,

it could have decapitated your brother in front of everyone

so no one would dare to go to Yipin Tomb.

Instead, it prevented Zhang Qinghu

from seeing this cruel scene.

It's rather empathetic.

The most important thing now

is to check if there are any other entrances

to this room.

You went to investigate the Zhang Brothers last night?

I've been looking for a chance to tell you.

I came out of Canglu Garden and followed them,

but they disappeared in the blink of an eye.

Why do you always make mistakes?

I always thought the seven thieves' corpses case

was done by them,

so they were vigilant and avoided me.

I didn't expect Zhang Qingshi

to become a headless corpse too.

Is there really some kind of sorcery?

I'm not getting involved in the investigation.

I'm not counting on you.

That's good.

Look.

Look.

The vent at the back of the room is broken.

If someone entered from here,

they could commit the murder without Zhang Qinghu realizing.

The entrance is just one chi wide.

How could anyone get in?

No adult could get in.

You mean the kid at the banquet?

That kid is sinister and vicious.

Zhang Qingshi had an argument with him.

It's possible that he would seek revenge.

Bastard.

Bastard! Stop!

Did you kill my brother?

Who do you think you are?

How dare you talk to me?

I'll crush your arm.

I'll see if you'll confess or not.

-Wait.
-You...

Wait.

Are you helping this bastard?

I’m just here to tell you

the murderer was someone else.

I received a secret letter

saying that a detective from Baichuan Court is among us.

The Zhang Brothers' martial arts skills are unique.

If they worked together,

it'd be hard for anyone to get the better of them.

He must have killed Zhang Qingshi

to weaken our strength

and make us suspicious of one another.

So Zhang Qingshi must have been killed by the detective.

In our trade, we meet once every few years

or not at all in person.

How do we know who is a detective from Baichuan Court?

I already know who he is.

"The hundred rivers flow down at once,

flushing away the murky and bringing out the clear."

Ge Pan, you are indeed from Baichuan Court.

Guards.

Drag him out and kill him.

Wait.

Master Wei,

there’s something wrong.

If the murderer were Ge Pan,

how could he

have avoided

Zhang Qinghu, who was at the door?

He wouldn't have been able to get through that small vent.

Exactly.

This little thing is the most suspicious.

Everyone,

I have a question.

I can vouch for my young elder.

Who dares to vouch

for the Baichuan Court's detective?

Even if he didn't kill anyone,

do we still want him to stay?

Since you have no objections,

let's send Ge Pan off.

Don't kill the innocent!

You're so concerned about someone from Baichuan Court.

Are you his associate?

I...

Hold on.

What advice do you have?

I'm flattered.

It's just that a detective of Baichuan Court sneaked in.

He must have backup.

If he has accomplices,

everyone will be in danger.

So my suggestion is

to spare his life for now.

After we find out the truth tomorrow,

we can rest easy.

Since Scholar Sushou has said this,

I have no objection.

What about you, Brother Qinghu?

Okay.

I'll wait for the good news from Scholar Sushou.

In that case,

thank you.

Guards.

Take him away.

Let's go.

There are so many detectives from Baichuan Court

at Wei Manor.

Do you know Ge Pan?

I've never trained at Baichuan Court.

I'm not sure.

But this weapon

indeed belongs to Baichuan Court.

So I had to save Ge Pan.

Thank you for helping me just now.

Thank you.

I wasn't helping you.

I’m afraid of death, Young Hero Fang.

We came in together.

If you start fighting,

I would be implicated.

After thinking about it,

I'd either have to rat you out

or help you.

I could only choose one of them.

Take it.

Rat me out?

What do you mean?

You haven't finished.

Fine.

I'll deal with you later.

There seems to be no entrance

other than the main door and the vent.

Did the kid really do it?

Let me ask you.

If you were that kid

and you wanted to climb into the room through the back wall,

how would you do it?

One, dig a hole.

Two, climb in.

Three, murder.

Take it.

The murderer's steps were different from what you said.

There's blood on it.

If he dug a hole through the bricks

before climbing in to kill,

blood wouldn't get on this brick.

There's blood on the brick.

It means the murderer killed

before making the hole.

So the murderer framed the kid?

What else?

But the murderer didn't leave any clues

in the seven thieves' corpses case.

Now, he's trying to frame someone else?

Do you think just because headless corpses showed up at Mount Buchu,

that it was all done by the same person?

You mean

these two cases might not be related?

I don't know.

I only know that the blood on Zhang Qingshi's clothes

seeped through the layers.

It didn't spurt out.

The blood splattered on one side,

but there was nothing behind the body.

So he died

before his head was chopped off.

He didn't die from being beheaded.

But he's dead.

Why the killer behead him when he was already dead?

The head is a very strange thing.

It can reveal a lot of secrets

whether a person is dead or alive.

What do you mean?

Now,

we need to investigate

Zhang Qingshi's case.

The murderer killed him

before digging a hole in the wall to frame someone else.

That means he must have entered through the front door.

But Zhang Qinghu stayed in the same room,

and didn't see anything.

What if they didn't

stay in the same room?
