I suddenly felt a little remorseful when I saw a huge shadow cast in the part of Cyrus's eyes, and the pitch-black vapor waves around the red edges erupted in the surroundings. One is because it's too close to Celeste, and the other is because it's ......

Why do I only have one hand left, ahh......h

"What nonsense, what kind of old lady kills! What the hell are you unconscionable one-armed fool trying to do! From beginning to end, you've been talking to yourself here for a long time, bastard! What do you say about the old lady killing is you delusional put! ”

The roar was so intense that for a split second, my entire brain circuit was interrupted. I was still rubbing my ears in pain until Cyrus' sonic attack was over, and I didn't have time to recover from the intense shouting.

"I said Cyrus, don't be so impulsive, okay......" Wiping the cold sweat on my head, I sighed, "If you discuss problems, you have reason to be reasonable, and you can talk about facts with facts...... When it doesn't make sense, it's not too late to yell and scream again - I forgot, you seem to have only one option left. ”

"Woohoo...... I was so rude just now, I'm so sorry," almost instantly, Cyrus suddenly returned from the state of a fried "little rabbit" to an elegant, dignified and unhurried appearance, "but what...... Onikawa must have been joking just now! In that case, as long as you can kneel down and lick my shoes seriously, I'll let you go a little. ”

"Wow yes...... The Queen's order is so exciting, it's better to give it to me Yamada Ichi, two, three! "Looking at Yamada's one-two-three, half shocked, half intoxicated, and mixed with some pleasant expressions, I really want to say who loves to lick who's going to lick.

"If you want me to say...... What are you doing in such a hurry to erect this victorious Flegg? Don't you just want to see the evidence of your own murder? I sneered, "How about we do another math problem?" ”

"Don't change the subject for me......"

"You shut me up cleanly!" My voice was raised an octave as well, yelling at Cyrus at higher decibels. When the roar was over, I turned my head, looked at the gossipy black and white bear on the throne in the judging field, and asked coldly, "Tell me, how big is the art room?" ”

Probably never been suddenly yelled at, Cyrus frowned, let out a "hum" from his nose, and took a slight step back.

"Huh? I'm not the answer......"

"If you want to see more 'desperate' flowers being bred and blooming perfectly in this academy, answer my question well," I interrupted the black and white bear's complaint in a rough way that I could think of and played, "how big is the art room?" ”

"Hmm...... It seems to be 70 square meters......"

Well, now, the efficiency of the black and white bear is much higher...... It's just that Miao Mu Cheng has been watching him for a long time with not very friendly eyes......

"Celeste-san," I glanced at Celence coldly, "before the dust settles or you plan to disarm and surrender...... I wonder, have you ever stepped on water? ”

What a gambler. The last second she was still immersed in an angry roar, but this second she suddenly reacted again, crossed her hands, looked at me with a hint of doubt in her eyes, and asked coldly: "What do you mean?" Is it related to the event? ”

"Very relevant," I slid my bangs with my only remaining hand, "which directly affects whether or not you are the murderer of Ishimaru-san." ”

"Okay then...... I haven't touched it," Cyrus seemed to let out a long sigh of relief, her eyes glancing into the distance, "the feeling of being soaked in water...... It's really uncomfortable. ”

"Thank you. Previously, we concluded that the volume of water in the art preparation room is about 3,000 square decimeters ×5.4 decimeters = 16,200 cubic decimeters. Now, the area of the art room + the area of the art preparation room = 100 square meters, which is 10,000 square decimeters. If you want to spread 16,200 cubic decimeters of water to an area of 10,000 square decimeters, the approximate height is 16,200 cubic decimeters÷ 10,000 square decimeters = 1.62 decimeters. At such a height, even Sakura-san, the great god is enough to cover her ankles. What's more, Cyrus-san? I continued to sneer as I watched Cyrus gradually become angry again, "It's just a pity that there is no dryer in this school. So, no matter what you do, you're bound to have a pair of shoes that have been soaked in water and haven't dried yet, and probably the same pair of black stockings. Right, Cyrus-san? ”

For a moment the crowd was silent.

"Black and white bear, what time is it?" It was Yamada Ichitoshizo who broke the silence.

"Huh? Could it be that this is also related to the case? The black and white bear turned his head curiously.

"I don't think the explanation of 'it's been too long, so the moisture on the shoes may have evaporated,'" I said with a soft breath and took out Yamada's cartoon camera from my pocket, "Come on...... Let's take a look at the photo at twelve o'clock last night. ”

On the big screen, a cartoon camera captured red high heels in the shoe cabinet appeared.

Everyone's coat and shoes and socks are made to order several pieces according to the same style.

In other words, these red buckle heeled sandals are only found in Cyrus's shoe closet.

The photo is not very clear. Even the blind could see in the corner below, the time of twelve o'clock in the middle of the night, and the splash of his shoes.

"Cyrese, do you have anything else to say?"

……

"I have something important to do, and I don't understand," after a long silence, Sakura Okami was the first to speak, "how did you know that Cyrus must tread water and enter the art room?" ”

Probably because I stole too much of the limelight before, and now I have to take back some of it, Kirkiri Hibiki gently brushed the braid on the left side of his head with one hand, as if he sighed to himself, "Probably...... Because of the Black and White Bear Archives. ”

"Black and White Bear Files?" From the bed where Fujisaki Chihiro was lying, there was a cry of surprise.

Speaking of which...... I don't know when it happened, but Chihiro Fujisaki suddenly woke up. In view of the fact that the reasoning is still in the climax stage, in addition to Naeki Makoto asked with concern, "Fujisaki-san!" How do you feel?", only Owada Wentu cared for him thoughtfully.

"Sapao, please read the second half of the last section of the Black and White Bear File. Well, that's right, starting with the last paragraph that Kikawa-kun read. ”

"Okay, okay...... I'm in charge of this kind of thing again......" Although there was a reluctant look on his face, Naeki Makoto still recited aloud, "There are yellow-brown bruises on the back of the neck, and oval-shaped gray-white patches. The margins of the plaques are convex, the central is concave, and the scars are hard and dry......"

“…… That's right, that's it," Naeki Makoto's words didn't fall, and the Kiri Hibiko interrupted him, "The difference is that Ishimaru-kun didn't die of ventricular fibrillation caused by electrocution in the water. Burns are also included. ”
