Kirigiri let out a squeal of admiration and joy.

[What, it turns out she can scream like this too. I saw many of her expressions during this period, which is really fun...]

May Yujie thought happily as she stood up on the stair platform, patted the dust on her clothes, and straightened her glasses.

What is written on the wall is [4f].

She looked up at the stairs. There was no way to go in the direction facing her. The corridor led to the right and had the same structure as the third floor.

"...By the way, why did I come here? It seems that I can find the answer to the secret room murder mystery here...?"

"Sister Yue, just go and take a look wherever you can. You will definitely know the answer soon."

"I see."

Although it's a bit scary to explore an unknown place alone, it must still be too difficult to bring Kirigiri here.

"I'm going to room '301'."

Kirigiri also immediately returned to the third floor.

Seeing this, Wuyue Yujie had no choice but to give up. She looked up at the stairs and started to climb up.

She had to go forward alone.

Although she had always been like this before, now that Kirigiri was gone, she felt that she really had no confidence in her heart.

She originally became a detective to save people, but in the end she keeps saving them.

If someone who can save others is a detective, then Kirigiri is indeed a well-deserved detective.

However, she will definitely deny this meaning and purpose.

The Kirigiri family's detectives don't need personal feelings, that's what she's been taught since she was a child.

However, she now also has doubts about the self she cultivated in her detective education.

Perhaps it should be said that she found a mystery in her heart that was difficult to solve.

Maybe one day, she can solve this mystery.

After walking up the stairs, there is an entrance leading to the interior of the floor just like the third floor.

However, unlike the third floor, the entrance door is closed.

The stairs no longer exist here, and the place where the stairs were originally has become a cement wall.

As expected, places that have nothing to do with the game are physically isolated.

Probably just like Kirigiri said, this place is designed in this way, and only those who can overcome danger can reach it.

May Yuyue stood in front of the door leading to the interior of the floor.

What kind of secrets might be hidden ahead made the girl feel uneasy.

"The chamber that seems impeccable at first glance actually has a gap somewhere, and this can be used to kill the victim from outside the chamber."

Kirikiri said this.

But when it comes to the gap in the room... there is obviously only one, which is the iron-barred window that lets in cold air.

[Is there something related to this on this floor?]

She held the door handle but couldn't open it.

If you look carefully, you can see that there is a slot for a key card under the door handle.

It seems that only those with 'detective powers' can open this door.

[Damn, I’ve come this far, I didn’t expect to be stumped by this door...]

May Yujie's face was dejected and she was really helpless.

But before she finished sighing, she suddenly realized something.

"...Hey, speaking of which, I am a detective now, hehe!"

The girl inserted the card into the card slot.

With a beep, the door lock opened.
Chapter completed!
