"There's a complaint, I have to say it now!" Suddenly, the black and white bear angrily waved its paws and yelled, "Listen to me, everyone! ”

“…… What's up? Interrupted by the search process that he was about to publish, Hibiki Kiriki scratched her hair unhappily and looked at the black and white bear.

"Fog Cut, I said, your shopping bag is also magical! From human internal organs to this black and purple hunting rope, there are all kinds of corpse slices left over from dissecting corpses! As he spoke, the black and white bear suddenly turned red, and his whole body trembled with excitement, "Could it be ...... Do you have an affinity for human corpses? ”

"Speaking of which...... This act of directly dissecting a corpse is really a hobby that makes people unable to breathe! Xiang the Exterminator laughed.

"Regarding the question of corpses, are you really qualified to judge others in this way?" Even Cyrus couldn't listen to it, and couldn't help but complain.

“…… Getting back to the point, "I looked at the black and white bear for a while with a caring look of intellectual disability, and Kiri Kiriko scratched her hair and groped for the end of the wire," the murderer cut off the rubber shell wrapped around the copper wire at the end of the wire, revealing the copper wire inside, and threw the wire on the floor of the art preparation room, and Ishimaru-kun was naturally electrocuted and then fell. ”

"Wooden floors?" Cyrus reminded.

"But there is water on the ground." I add.

"But there is only one tap in the pool. How much water do I need to put in order for electricity to pass through the ground and kill Ishimaru-kun? Cyrus asked.

"Huh? Think about it for now...... That's a big number, indeed. Naeki Makoto's eyes widened in surprise, "With such a small pool, you want to let the water overflow the art room......"

Hibiki Kiriko opened the slotted shopping bag again and threw a ...... out of it

"Huh? This is...... Waterproof plastic paper? Naeki Makoto looked at Hibiko Kiriki with a surprised expression.

The latter took out a large, neatly folded piece of plastic paper from the plastic, grabbed both sides of the plastic paper in the air, shook it away to the crowd, and said as he shook it: "This thing was found in the locker of the indoor swimming pool." On the four edges of the waterproof plastic sheet, there is a faint trace of being glued by waterproof glue. So before, I investigated the door frame of the art preparation room, and I also had some glue sticking. ”

In other words...... If the assailant was not mistaken, the killer must have glued a waterproof plastic sheeting to the door frame of the art preparation room, plugging the gap and creating an improvised dam. In this way, there is a possibility that the water in the art preparation room will spread to a fatal height if the electricity is turned on, right? I glanced at Celence, "Killing people has to be carefully planned, it's hard for you." ”

"So here's the problem. Where should you stick your so-called waterproof plastic sheeting? ”

When Cyrus asked, Kiri Kiriko threw me a "you answer yourself" look. Then she scratched her hair and stopped Naeki Makoto with her eyes as if she was about to give an answer.

"Inside," I replied, "when Ishimaru-san unveiled the waterproof plastic sheet and entered the art preparation room, water gushed out from the inside out. It is difficult for someone standing outside with a wire in hand to attack Ishimaru-kun at the right time. ”

The atmosphere on the field became awkward again. It's as if someone other than Cyrus and I have just reached a silent consensus with our eyes.

"You mean, I put a waterproof plastic sheet on the inside of the door, and then I stood in the art preparation room, waited for the other party to come in, threw the wire under the feet full of water, and electrocuted Ishimaru-kun?" Cyrus gasped for a sigh of relief, "But is there really any clean place in the art prep room where I can stand?" Besides, how can I guarantee that Ishimaru-kun will definitely open the door of the art preparation room? ”

"Do you think that water is the conductor of Ishimaru-kun?" I sighed and shook my head, sneering, "Forget it, let's talk about the reason why Ishimaru-san had to enter the art room." Kirikiri-san, give me the wire. ”

As I spoke, I showed a new picture on the big screen. This time in the art room, there was still a thin layer of water on the floor, and some white and pink things were floating in the water.

The next photo is a close-up of the carpet at the entrance of the art room. This was not a big deal, because the ground on the third floor of the entire school building area was covered with this kind of carpet. The only difference is that this place ...... It's a little wet.

"But no matter how good the quality of the waterproof plastic sheet is, it can't completely block the water in the art preparation room and prevent it from spilling out—oh, you don't need this effect either—if a pool of water is found in the corridor outside, as a super-university-level member of the Discipline Inspection Committee, will Ishimaru Kiyotaxia drag it dry and check what's going on?" I glanced at Owada Monto, who turned his head a little embarrassed. Is he—remembering his brother who died in Huangquan again?

Cyrus unexpectedly didn't answer, presumably...... It's because she feels that she has nothing to say.

"Of course, you weren't in the art room when Ishimaru-san entered it," I continued, "and you should be hiding behind the corner of the corridor leading to the physics room, watching Ishimaru-san's every move. As a member of the Discipline Committee of the Super University level, the iron-like discipline has penetrated into his mind, and when he sees the situation of water in the art room, he will definitely want to find out the reason. It makes sense to push open the door of the art preparation room. ”

"Hey...... Wait! Owada Wentu interrupted in surprise, "If the brother doesn't open the door, won't the plan fail?" ”

"It's up to Ishimaru-san and Cyrus-san to create it," I sneered, "A super-college-level gambler should be very convinced that he has the characteristics of lucky favor, right?" ”

"That's not right." Just as I was about to continue, Cyrus interrupted me suddenly.

Out of politeness, I raised an eyebrow at her.

"I didn't find a socket in the art room," she sighed, "If there is no power in the art room, and I'm standing outside the art room, how can Ishimaru-san be electrocuted?" ”

"Hmph...... Didn't you notice that this wire is too long? I pointed to the wires on the Kiriki-saki desk, "This should be the extension cord behind the lamp when Togami-san was researching murder methods in the library, right?" One end is tucked in through the crack in the door, and the doorknob clamps the thread; The plug at the other end is connected to the socket used for the experiment in the physics room and energized. In this way, the art preparation room in front of Ishimaru-san is a hell stop! ”

"Do you mean that if anyone opens this door, they will welcome death?" Sho the Exterminator nodded and looked at me with a smile, "Okay, okay...... I have to say, what an apt and vivid metaphor of death! ”

I can see everyone on the field, one by one, the brows are gradually stretched, or suddenly realized, but I don't feel happy. Not because of something as trivial as Cyrus killing someone, but because of ......

"Onikawa...... Are you challenging me? When Cyrus dragged her chin with her hands and raised her head again, there was no wave on her smiling face, "Okay." Let you see my strength, right? ”

A vague smile faded from Celeste's face. What suddenly appeared behind her was something strange.

A dark red, pitch-black wave of air spread from behind Cyrus in all directions. It's not the same as my gray-black airwaves, what I bring is a repression, Cyrus's airwaves...... There is a mysterious sense of allure.

"I haven't lost a single gamble," she said, "this time...... It won't be an exception. ”

"Good record, keep it up...... However, I'm not interested in betting with you," I burst out laughing as I watched her eyes sink into shadows, "I'm just...... I want to see you cry. ”
