Perhaps Natsuki Sasahara was thinking about concealment, and there was no door number hanging outside this study.

It looks like a house that has been idle for a long time.

Xicheng Shi and the White Mist Divine Son opened the small iron door for decoration, and their eyes swept around.

The small courtyard was overgrown with weeds, although it was not waist-high, but it was already about the ankle of a person.

Xicheng Shiki and the White Mist Miko came to the door.

The cracks of the security doors have not been used for a long time, so they show stains of rust, and the doorknobs are covered with dust and white cobwebs.

The walls were covered with blackened mold.

This gloomy place is very similar to the 'murder house' in movies or TV dramas.

Even if it's still early, it gives people an indescribable sense of oppression, which really feels like the movie "The Grudge".

"Shiki-kun, do you have the key?" The White Mist Divine Son, who was following behind, asked, and didn't feel too scared.

After all, she is not an ordinary girl, as the god son of the White Mist family, she has basically seen all demons and monsters since she was a child.

"No keys."

Xicheng replied in the style of a sentence.

"Don't use a key?" The White Mist Divine Son couldn't help but glance at Xicheng Shi, and then couldn't help but glance at his palm.

Could it be that Xicheng intends to open the door directly physically? Tear the gate by hand?

But what can I say...

"It's... It's a bit out of place, right? It's too violent. And the sound will also affect the people who live in this area, right? It wouldn't be nice if they called the police. The White Mist Divine Son touched his head and said.

"Huh?"

Xicheng Shi glanced at the White Mist Shenzi, and immediately saw what she was thinking, so he opened his mouth to explain: "I don't have any intention of messing around at all. ”

Although it is relatively quick to start directly on the security door.

But as the White Mist Shenzi said, if he tears the security door with his hands, causing a loud noise here, which causes ordinary residents to call the police, it will be a lot of trouble.

So this option is to tear off the security door... It's a bit of a pity, but I'll have to keep it at the last option.

However, this does not mean that the West Side style cannot enter it.

He held out his hand.

Mori Bai's mist also appeared under his hand.

The white mist of the forest poured directly into the keyhole under the control of the West Castle.

Immediately after that, with a single stroke of the Nishijo-style fingers, the mist of the white coffin instantly condensed into an entity, matching the shape of the keyhole.

Quack –

With a crisp sound of the door opening, the locked security door opened.

The shaping properties of the mist are still very useful.

"Let's go."

Nishijo walked into the house without hesitation.

A cursory glance at the past.

The first floor of the study is a simple furnishing.

A dusty table, an old TV that hasn't been used for a long time... As well as a couple of benches, two large bookcases.

Aside from these furnishings, there is nothing left on the first floor.

It seems that Natsuki Sasahara and Koji Sasahara have really taken the office to the extreme, and they are not prepared for any relaxation at all. Something for entertainment.

The ground floor was pretty much that, couldn't find any useful information.

However, considering that there are still two bookcases, the White Mist Shenzi also took the initiative to investigate.

Leaving the White Mist Divine Son, Xicheng came to the entrance.

Next to the entrance is the staircase leading to the second floor, which is made of wood, and because it has not been used for too long, the original paint has faded, giving it a crumbling appearance.

From this staircase, which is at a right angle, the Nishijo-style goes up to the second floor.

The overall area of the second floor is smaller than that of the first floor.

The room layout is also very simple.

To the west of the city, on the left-hand side, facing the study.

If you look to the right, you will see a Japanese-style room that looks like a bedroom through the corridor with square corners.

Xicheng style is the first to enter the study.

The furnishings of this study are exceptionally simple.

The two desks merge together to form a large desk, with standing bookcases at the corners of the walls and a transparent glass display case on the top floor.

Inside the exhibition case are local customs items from all over the world.

For example, the quaint hand mirror, the eerie ghost lantern puppet, the shiny stone...

A hint of death flashed in Xicheng's eyes.

Under the vision of death, you can clearly see the things that are wrapped around these ordinary-looking souvenirs...

Resentment.

That's right, these items in the display case are all objects with resentment.

Xicheng style eyebrows raised.

It seems that Natsuki Sasahara and Koji Sasahara are not just folklorists.

Because resentment is transmitted.

If the average person puts so many items with resentment in the house, the body will also deteriorate due to the erosion of resentment, and become sick and irritable.

But Natsuki Sasahara and Koji Sasahara did just that... And judging from the data, there is no problem with their body.

Then the answer is simple.

Only people with special abilities can protect themselves before they hold grudges, in other words, Koji Sasahara and Natsuki Sasahara are certainly not ordinary people.

And their research... There must also be secrets hidden that ordinary people can't detect.

Thinking of this, Xicheng-style gaze downward.

As far as he could see, there were A4 printing papers scattered all over the floor.

These data papers are either oxidized and yellowed, or the surface is mildew, black and white.

The whole study looks messy.

“... Is it there? "Xicheng looked at the window of the study.

At the glass of the window, a large hole was shattered.

It appears that the wind is seeping through the broken window into the room, blowing all over the place where the documents were originally placed on the desk.

No way.

I had to go through the survey materials while packing up.

Xicheng lowered his body, picked up the information paper that could still see the handwriting one by one, and sorted it out.

But he soon found out—

"It's too slow."

Nishijo rubbed his temples.

That's right.

It's too slow.

Because Natsuki Sasahara and Koji Sasahara have a wide range of subjects.

From the social folk customs or rituals of a certain period and place, as well as the social phenomena of the time represented by these things, down to the reasons for the popularity of a certain industry and a certain local product in a certain place.

All in all, as long as it is human activity, what can once be regarded as human confusion behavior is basically within the scope of the research of Natsuki Sasahara and Koji Sasahara.

But for the West Side, this is just ordinary useless information.

But out of the idea that he would rather kill by mistake and not let go, Xicheng had to go through the past one by one.

This leads to unwarranted waste of time.

I finally finished reading all the materials in my hand.

Nishijo didn't find any useful information, but instead made up for some knowledge of Japanese folklore.

He put down the pile of papers, looked away from the paper scattered on the floor, and instead looked at the desk setting.

The desk wasn't neat, but it wasn't too dusty.

After all, it's right on the tuyere, which is also normal.

Nishijo flipped through the documents on his desktop cursory.

The basic content is similar to these documents on the ground, which are all studies of the folklore of a certain place, which is an ordinary record of the words spoken by some locals, as well as local legends, cut out newspapers...

But... If it were Xicheng style, it would definitely not be possible to put those research materials involving supernatural and weird things on the table so directly...

Nishijo looked at his desk.

Looking at the desk drawer, to be exact.

There might be some clue hidden in there.

The drawers are pulled apart, and the neatly bundled letterheads are placed in the drawers.

The letterheads were thick, and some of them seemed to have something in their pockets, and a cursory sweep of them should have been dozens.

That's really enough retro contact.

Xicheng Shi took out a letter and swept it away.

Sunday, June 12, 2016. ’

'Earlier, it was already evening when we arrived at our destination, and we spent a lot of time looking for a room. Luckily, there was a friend I knew among the locals who promised us to stay at his house for the night. Koji and I have been here three times, and this time it's still so fresh. I think I think I will be able to conduct a good investigation this time. ’

'Miss Oe, how are you doing with Yuki in Tokyo?' Hope to hear back from you soon. ’

At the bottom of the letter paper is the name written in upright and beautiful handwriting - Natsuki Sasahara.

Then this should be the letterhead that Natsuki Sasahara sent to Tokyo to Oemurasaki...

It's just that the reason why it was left in the study is unknown.

Looking at the letterhead, Nishishiro fell into thought.

At first glance, it may seem like very little information can be extracted from this letter, but in reality it is not.

The first is the date.

June 12, 2016.

If Nishijo is not mistaken, he had received such a piece of information from the information about Sasahara Natsuki before-

Natsuki Sasahara's husband, Koji Sasahara, was killed at a folk event in 2017. ’

If you look at it from here, the time should be right.

The second point is the phrase 'Koji and I have been here three times'.

What is there in that place that deserves such attention from Natsuki Sasahara and Koji Sasahara?

And the third point is...

Xicheng turned the envelope over and swept his eyes away.

The dry brown envelope is covered with a neatly upright postage code.

649-0155。

If I remember correctly, this zip code should be the zip code of Hainan City, Wakayama Prefecture.

In other words, Natsuki Sasahara sent a letter from Wakayama Prefecture.

The West Castle style palm is turned again.

And then he found out.

Most of the letterheads were sent from Wakayama Prefecture.

The time period mainly stays from the first half of 2016 to the second half of 2016.

By 2017, the number of letters sent had dropped dramatically, and although there were occasionally one or two, the content...

Xicheng casually opened the letter sent in 2017.

I'm here, and it's still here. I can still feel Koji's voice lingering in my ears to this day. He asked me to investigate... Go find out the truth... Find out what the family's... The truth of that history. Koji is still with me, I can feel it. ’

'Thank you. Miss Oe, I'm going to make it... It will definitely work. ’

No signatures, no dates...

But there is no doubt that it was a letter from Natsuki Sasahara.

Postal No. 649-0155.

It's still sent from Wakayama Prefecture.

From the contents of this letter, it is not difficult to surmise that Natsuki Sasahara was heartbroken by the death of her husband, and it seems that she also had visual and auditory hallucinations.

"Wakayama Prefecture."

Xichengshi stared at the postage number on the dry brown envelope paper, his eyes narrowing slightly.

He thought of what Kitagawa Temple had told him.

Original owner... That is, the Nishijo style, and he is also a native of Wakayama Prefecture.

All the clues are connected.

Natsuki Sasahara's so-called folk style is inevitably related to the Nishijo style.

And the 'family' mentioned in the letter must also be the Xicheng family.

"It seems that it is still necessary to go to Wakayama Prefecture once."

Xicheng style put down the letterhead.

He was satisfied.

This time, I still have a harvest.

At least know where Natsuki Sasahara went last.

Just as Nishijo was about to go to Sasahara Koji and Sasahara Natsuki's bedroom to take a look, the voice of the white mist miko came from downstairs:

"Shiki-kun! Come here! ”

She shouted the name of the West Side repeatedly, looking very excited.

The White Mist Divine Son's side seems to have discovered something.

Xicheng quickly went downstairs and came to the staircase where the White Mist Miko was.

At this time, the white mist god was standing at the bottom of the right-angle stairwell, she was carrying her mobile phone, and the brilliance of the mobile phone flashlight shone towards it.

"Shi-kun, look at this stairwell, something is wrong."

Seeing Xicheng style downstairs, Bai Mist Shenzi turned sideways, and his mobile phone lit up into it.

"Is this...?"

In front of me is an ordinary stairwell with a lock hanging on it, which is supposed to be used as a general storage room.

But—

Xicheng pinched his chin, and soon realized that something was wrong with what the White Mist Miko said.

"This stairwell is too deep."

He spoke his own judgment.

The so-called depth is actually the distance from the front wall to the back wall of the building.

If you look at it roughly, the overall depth of this stairwell should have reached three meters, and it even affected the layout of the rooms behind.

In general, you don't need such a large stairwell.

Unless...

"Unless it's to make room below." The White Mist Divine Son thought for a moment and said his answer.

That's right, if such a design was taken for the sake of paving stairs in the basement ... This is not surprising.

And if you take a flashlight and sweep it little by little, you will find traces of a hidden door that is deeply hidden.

"It's usually used as a normal stairwell, but there's a secret door underneath..."

The West Side style is becoming more and more interested.

What exactly did Natsuki Sasahara and Koji Sasahara study.

I even have to make a home basement.

He directly shaped the mist and began to pry open the secret door.

Click... Click...

It seems that it is the reason why it has not been used for a long time.

When the Xicheng style pried the secret door hard, the wooden board next to it made a very unpleasant sound.

About half a minute later—

Boom!!

Bang –

First there was a crisp sound, as if something had been pried open, and then there was the long, muffled sound of a secret door being opened—

The old ash that had accumulated in the stairwell rose in an instant, making both Xicheng Shi and the White Mist Divine Son take two steps back.

"Let's wait for the ventilation inside."

Looking at the dusty stairwell, Xicheng suggested a sentence-

That being said,

But there are clues in front of you... A man of action like him is actually a little uncontrollable.
