"What is Onuikawa searching?" Cyrus smiled and stepped into the physics room, frowning at the sight of the remaining blood from Ishimaru Kiyotaxia.

I have to say, her expression was so well done that I almost believed it.

"It's not a search, just look for it," I still looked around, "The murderer is really a careful person, and there is no trace left." ”

Cyrus didn't answer me. Strange, I'm kind of wondering, what is her expression now?

"What about you? What did you find? "I kicked the ball back to Cyrus.

"My side...... It's not a search," Cyrus decided to ignore the bloodstains of Ishimaru Kiyotaxia and walked directly to the physical preparation room in the back, "I'm just thinking about where Rein Kuwata's body will be hidden." ”

"Is that so......" I nodded, muttering to myself for a while, and involuntarily walked towards the preparation room, seeing something unusual.

That's a longer rope. Its end is tied to a pedestal below the air purifier's operating interface. If I hadn't happened to avoid the approaching Cyrus, I'm afraid I would have ignored it.

And...... This rope seems to be a little longer. What is it used for?

Wait a minute...... Rope...... Impossible, right?

Luckily. Miss Murderer's sudden appearance made me have a flash of inspiration in my mind, and I turned around and ran out of the physics preparation room as fast as I could.

……

"What is the matter with Onikawa-kun calling me so urgently? Ishimaru-kun's Bones ......"

It's really a little annoying to the ancient text of the great god Sakura.。 I hurriedly interrupted: "I'm looking for you now, it's also a need to investigate the case!" There is one thing that will be difficult to unravel without the help of your strength. ”

We pushed open the door to the physical preparation room. Thankfully, Cyrus is nowhere to be found.

Under Sakura's stunned gaze, I pointed directly above the blurred bloodstains. She looked up at the beams, then at me, and shook her head in confusion.

I said...... Don't you see a broken rope tied to the beams? I slapped myself hard in the face speechlessly.

After staring at the rope for a long time, the great god Sakura suddenly looked at me: "What do you mean, do you hope I can take that rope off?" ”

Before the words fell, the great god Sakura disappeared in front of me; Looking up in surprise, a man patted me on the shoulder and handed me a rope.

That's right, it was the Great God Sakura who handed out the rope, and on closer inspection it was far from the unworn end, and I saw a neat, slightly inclined cut.

“…… Answer correctly. "It was only then that a sentence that was not too chaotic came out of my completely dysfunctional language organization system.

Sakura Okami left without looking back. Having settled down, I regained my thinking skills and logical organization skills, and went to the warehouse with the rope.

……

As I descended the stairs and passed near the pool on the second floor, I heard Owada Monto complaining in the direction of the locker room.

Opening the door slightly, I saw that in front of the two doors of the two locker rooms, Sakura Okami was talking to Owada Wentu emotionally.

"Guanru's emotions just now...... Seems slightly excited. Don't know what's going on? Sakura asked calmly, still with her arms folded.

"Ah...... I found a problem, the things in this school warehouse seem to be a lot less all of a sudden...... "Because of the door panel, from my point of view, I can only see Owada Wentu scratching his hair with one hand.

"That's right...... So, what's missing in the warehouse? From here, I couldn't see Sakura's expression at this moment, I could only hear her tone of voice as if she was indifferent to the matter.

"Needless to say? Hairspray, of course! As he spoke, Owada's tone suddenly rose several layers, "Uncle Ben has always had the habit of taking hairspray from the warehouse to fix his hairstyle!" But just now I found out that there was not a single bottle of hairspray in the warehouse! ”

"Maybe you've used it up, but you haven't been aware of it?" Okami Sakura glanced at the exaggerated head of the plane with Owada's pattern and said, "Ru's hairstyle must use countless hairsprays." ”

"How is that possible!" Owada Wentu retorted angrily, "I just checked it last night, and there are more than a dozen bottles of hairspray!" ”

"That's right. Don't worry, maybe other people like you like to use hairspray. ”

"Damn!" Owada Wentu waved his fist angrily and shouted, "Who is it!" Secretly ran out of hairspray for me! It's really the third worst act after killing brothers and bullying the weak! Whoever catches me, I'm going to have to give him a good look! ”

Owada Wentu is still going crazy. I don't think anyone will notice me...... Ignoring this strange conversation, I didn't look back downstairs.

Probably...... It has nothing to do with the event......

……

As I approached the dormitory area, I noticed a figure that seemed to be hurrying through the hallway of the dormitory and had lost its sight around the corner.

Leave him alone. I pushed open the door to the warehouse and rummaged through the boxes and cabinets to find where the tape measure had been placed.

Got it! Without saying a word, I took out my tape measure and began to measure the length of the rope.

No...... Fools can see that this texture is not the texture of a rope, but something that I am very familiar with. It's just a late appearance.

But that's not the point. I took out my tape measure and measured the length of the two ropes section by section.

Hanging on the roof, about 50 centimeters. I remember. The cut part of it hung from the beams and seemed to be very short, about 10 centimeters.

And the rope sleeve on the ground, the length is 50 cm.

From the cutting point to the knot...... 30 cm.

Tut...... How is this possible? Is it only thirty centimeters? If it was really Cyrus or Yamada's one-two-three, how did they tie the rope noose without the help of climbing tools?

I suddenly remembered what happened last night.

The female voice ...... It should be Cyrus.

If you say...... If you really can't do it, you can only go to the laundry room and try that trick.

I measured the longest rope that had been hidden in the corner at first.

Well, this rope...... Seems a bit of a surprise to me. It is almost 3.6 meters long.

I'm not good at arithmetic, but my brain still spins fast, reminding me to hold a computer.

Remember that from the pool of blood to the leg of the tether, it is about 1.2 meters. If the smooth and flat ground is a straight line, then if you pull a dotted line from the foot of the hoisted Ishimaru Kiyotasha to the ground...... It should be perpendicular to the ground......

Damn arithmetic questions...... It's a headache...... It would be nice if Ishimaru Kiyotaxia was here, he is the Olympiad champion......

When I thought of Ishimaru Kiyonatsu lying so miserably in the pool, and yet, for the reason I couldn't say, I had devised a plan to save other people's lives in order to save her, and I felt a sudden feeling of guilt in my heart.

When my mind calmed down, I walked to the back of the warehouse and opened the cabinet door of the "hairspray".

The inside of the cupboard was really empty. It's as empty as ...... It's like never letting go of something.
