The High School Affiliated to Fengcheng University, the fourth teaching building.

This school building has the longest history, it has existed since the beginning of the school, but in recent years it has ceased to be used for teaching, and the four-story school building has a total of 16 classrooms, which have been converted into activity classrooms.

The Department of Mystery Research is located in Room 4 on the side of the fourth floor, and according to Mio Amamiya, it was the minister who chose the classroom at the time who found the number to be very mysterious.

In the ten years since its establishment, there have been no mysterious incidents in the Department of Mystical Research.

After all, the students who join are ordinary people.

At its most glorious time, the club had twelve members, and now there are six people, which is no more, no less.

After all, there are still some societies with only two or three people and on the verge of ruin.

It's already a luxury that the Mystic Research Department can still worry about the project of the Peak City Festival!

The members hadn't arrived yet, but Qiao Qiao and Mio Amamiya were already sitting in the classroom.

I don't know why, but there is also Natsume's poetry.

"As a member of the Discipline Committee, it is very reasonable for me to supervise the preparatory work of the association."

Natsume's poetry lit up the armband of his own discipline committee.

After all, Qiao Qiao has a history of blasting shoe cabinets, and if there is any bigger news this time, it will be a dereliction of duty on the part of the Discipline Commissioner.

"Besides, Mio-chan is my good friend, and I can't let Qiao San teach her badly."

Looking at Mio Amamiya, who was sitting obediently, with some concern, Natsume's poetry emphasized.

As a shrine maiden of Toshogu Shrine, she naturally heard about the Gion Festival in Kyoto.

Shimogamo Shrine, until now, is also a strange and terrifying existence in Kyoto's circle of soul slayers.

It's like being infected by the Qiaoqiao virus.

No, I have to prevent the quiet, well-behaved and sensible Mio-chan from being infected!

"Why are you still wearing a mask, Natsume-san?"

Qiao Qiao looked at Natsume's poetry who was trying to put on a mask for Amamiya Mio with some confusion.

"To prevent the spread of the virus."

Natsume said solemnly.

"Has hay fever gotten so bad lately?"

Although Qiao Qiao does not have this common problem of crooked nuts, he also has to consider whether he should get a gas mask or something.

"Let's not mention this for the time being, is the Peak City Festival project of the Mystery Research Department sure to be a haunted house?"

Natsume looked at Mio Amamiya and confirmed.

"Hmm."

Mio Amamiya nodded.

"I don't know what this guy said about you."

Natsume's poetry is a little helpless, but since it is Mio Amamiya's own decision, then she can't interfere as an outsider.

"So, I've got a basic blueprint here."

Qiao Qiao took out a blue drawing from his school bag.

"Wait a minute, isn't it just a classroom to set up a haunted house, as long as you take out the desks and chairs or something, you can have a spacious place, right?"

Natsume asked a little strangely before she saw the drawings.

"I looked up some information about haunted houses on the Internet, summarized some of the reasons why haunted houses are frightening, and came to a conclusion."

Qiao Qiao unfolded the blueprint.

"That's the unknown."

"Unknown?"

Natsume's poetry is unknown.

But Mio Amamiya's eyes suddenly lit up.

"The oldest and strongest human emotion is fear, and the oldest and strongest fear is born from the unknown."

She muttered to herself.

"That's good, Amamiya-san has mastered the essence of the haunted house."

Qiao Qiao praised.

"The haunted houses of ordinary cultural festivals are all arranged in classrooms, and this kind of haunted house is quite safe at first glance, and a lot of fear has been reduced from the outside."

He glanced at the classroom.

"The familiar place where everyone usually stays can't be afraid, just like the fixed time of a horror movie, the protagonist and his party must have come to a strange big house, and it is precisely because of the unknown that it brings a sense of psychological oppression."

"I know this!"

Mio Amamiya nodded vigorously.

"It's like in 'The Shining', where the protagonist goes to an unfamiliar hotel, which triggers a series of horror events."

“？”

Natsume looked at her friend who suddenly became excited, and felt a little strange.

Mio-chan is originally fond of this kind of horror movie?

"So, we need to carve out an area on campus and build a haunted house on its own."

Qiao Qiao said.

"Wait a minute, open up a separate area?"

Natsume's poetry felt a little incredible, although the Peak City High School covers a large area, but during the Peak City Festival, a lot of open space is also needed for various outdoor club displays, how can there be a surplus area for the Mystery Research Department?

"Well, I've already applied to President Ii for approval, and it's about the size of four classrooms in the area north of the playground."

Qiao Qiao nodded and continued.

"Let's ask Amamiya-san to see the design drawings first."

All three turned their gaze to the blueprint.

“？”

Natsume was stunned.

On the drawing, this large area is divided into four parts.

The location marked with the entrance is the first area.

Crazy Mountains.

"Wait, wait, what is the Crazy Mountains?"

Natsume poetry doesn't quite understand.

Is there any connection between a haunted house and a mountain?

"Ah, is this the Crazy Mountain Range?"

Mio Amamiya became even more excited.

"That's right, in the first area, we'll have visitors as explorers, climbing mountains and encountering all sorts of weird events that are unknown to them."

Qiao Qiao explained.

"But what's so scary about climbing a mountain? Also, even though the area is large, it's still difficult to achieve height, right? ”

Natsume's poetry is not very well understood.

But after all, this is just a design drawing, so you should know when you actually make it.

With this in mind, Natsume looked at the second area.

Star Color.

Is it an area like a planetarium?

"This seems pretty normal...... No, why is there such a literary area in a haunted house? ”

Natsume's poetry instinctively sensed something was wrong.

"The second area is a forest, where visitors will meet all kinds of unknown monsters, and even the visitors themselves will change."

"I know this! Star Color, right? ”

Mio Amamiya patted the table gently.

"Visitors themselves change, hey, this seems to be completely beyond the business of haunted houses, right?"

Natsume felt that she didn't have the strength to complain.

She looked at the title of the third section.

Shadow of Innsmouth.

"What does this mean, a name I've never seen before?"

Natsume's poetry is not interested in horror movies and literary works, after all, he is a soul exterminator, and it always feels a little hypocritical to see the scenes of ordinary people in the movie being slaughtered by resentful spirits in fear and wailing.

Naturally, there is no way to know the name.

"The third area is the ocean, where visitors will go deep into the sea to explore the unknown megacities that have sunk into the sea, and at the same time they may be attacked by monsters."

"Wait, wait, anyway, it's impossible for the ocean or something to reappear on campus, right?"

There are pools and swimming lessons, but for some physical reasons, Natsume doesn't like swimming.

Ignoring Natsume's poetry, Qiao Qiao pointed to the fourth and last area in the expectant eyes of Mio Amamiya.

Call of Cthulhu.
