"This was found in the incinerator of the garbage room, Kuwata-kun's ashes. Well, in other words, this should be the rest of his ashes," Hibiki Kiriko said, scratching the braid on her right, "By the time I got to the garbage room to look for clues, there was not much ash left." Fortunately, when I first arrived at the garbage room, the murderer seemed to have forgotten something and didn't even turn off the incinerator. ”

As the last sentence came out of the Kirkiri Hibiki, I could feel Cyrus looking at Yamada Ichito-Sano with a look of disdain. In this regard, the latter could only put his hand into his mouth in embarrassment.

"Hey...... Wait a minute......" Enoshima Shield's eyes widened as if she had just heard something appalling (well, as far as I know about her, I don't think it should be something appalling), "Kirikiri-chan...... You seem to be saying...... In the incinerator, only Kuwata-kun's ashes remain? ”

Hibiki nodded affirmatively.

“…… What do you mean? Enoshima Shield's face became more and more ugly, "Ashes ......"

"Because Kuwata-kun's body has already been burned by the murderer," Hibiki Kiriki also took out some bags containing small metal objects from the basically empty shopping bag, "Well, this is something that can't be burned." It's all Sangtian-kun's close-fitting metal jewelry, right? ”

"How can you be sure that the Fog Cutting Hall must be Sangtian-kun's ashes?" Yamada Ichito-san looked at Hibiki Kiriki with a gloomy face and asked, "Maybe...... This should be, just some other dust, right? ”

"Like what?" As soon as I noticed a flaw between the lines, I immediately followed up.

"I'll admit, it's a problem," Hibiko Kiri sighed, touching her hair, "Black and White Bear, I'm going to experiment on the spot!" ”

"Uh-huh?" The black and white bear tilted its head suspiciously, one paw covering a cracked fangs on the left, and its eyes flashed with a cold and deep glow like an infrared flashlight...... How can we help? ”

……

"Well, let Ben Xiong take a look...... Beaker...... Alcohol burner...... Small Hammer ...... Small metal grinding table...... Small sticks...... A clean little bag! That's くま! It's all there! ”

Closing a folder with the head of a black and white bear printed on it, the black and white bear raised one of his arms and shouted to us with joy: "Okay, okay! So far, everything you want from Kirikiri is ready! Let's take a good look at it, the operation of the fog cut classmate, right? ”

As she spoke, Hibiko Kirikiri had already pushed away Sayaka Maihara's judgment table and stood in the middle of the circle around us, in front of the experimental platform provided by the black and white bear. The wardrobe and clothes that were previously placed here have now been cleaned up, and fireproof cloths have been laid on the floor for fire prevention.

"But speaking of which, Kirikiri-san, what are you going to do?" Looking at the fog cut Hibiki outside the purple glove, and then put on a layer of medical gloves, the black and white bear suddenly asked.

But the mist cut Hibiko had already picked up the small piece and rubbed it vigorously on the grinding disc. At this moment, the solemnity of the atmosphere reminds me of the men and women who watched and prayed around the high priest during the large-scale rituals in ancient times.

After three minutes, the debris finally turned into a pile of white powder. But when it comes to powder, it's more like a large pile of gray-white particles. It does not have the delicate feeling of flour, nor the lightness of pearl powder as soon as it is blown away, but the graininess of stacking together is very strong.

Finally, when he saw Hibiki Kiriki pushing the powder together with a small wooden stick and putting it into a small evidence bag, Miao Mu Makoto couldn't help but ask, "Speaking of which, Mr. Kirikiri-san...... What the hell are you up to? What is this fragment? ”

Maybe it's a relationship that's too busy. For a moment, Hibiki Kiriko didn't even have time to raise his head to answer. Miao Mu Cheng asked again, and at this moment the powder on the table had been collected, and the mist cut Hibiko took a light breath, clapped his hands, and said to us:

"This is Kuwata-kun's bone scraps."

……

A minute passed.

Two minutes passed.

Three minutes passed.

Four...... I don't know how many minutes have passed.

It was probably a voice in my heart that reminded me that it was time to break the silence that I could hear if I let the embroidery needle fall on the ground, so I cleared my throat and asked the misty chirping of the evidence bag in my hand: "What are you going to do?" ”

Maybe for the mist cut Hibiko, if it is not amazing, it should be very purple horse milk. She scratched her hair and came up with a very startling explanation: "Sprinkled in an alcohol lamp." ”

There was a loud "thump" on the left. Turning his head, Cyrus poked forward in surprise, leaning weakly on the table with one hand, his eyes wide as he looked at Hibiki Kiriko in surprise.

It follows that if even the initiators were so surprised, I would be even more surprised.

"In the heat, the blood, skin, muscles, and organs of a person are incinerated, but the bones are still ashes," Hibiko Kiriki explained, "that is, ashes." The best way to test the ashes is to scatter them on the fire and watch the flame react as it burns. The composition of the ashes is similar to that of apatite, so if you sprinkle it on the fire......"

"Wait!" Okami Sakura suddenly shouted.

It's too late to move. Because the mist cut the ringer has already put part of the powder into the beaker, and the other part ...... Sprinkle directly on the alcohol lamp.

In the roar of the great god Sakura, we see a dazzling white light, and we also see a wisp of inconspicuous but impossible to ignore white smoke rising.

"You said it in chemistry class, right? Phosphorus when exposed to fire produces a harsh white light and produces white smoke. If anyone still doubts, when heated, the apatite will produce phosphorescence, which makes us ......"

Unexpectedly, this time everyone shook their heads and waved their hands in unison, and replied with an embarrassed smile: "No, no, no...... There is no need to continue the experiment, we admit that it is Kuwata-kun's ashes......"

…… So, why don't you have the courage to face up to the disgusting thing......

"Speaking of which...... Is the bag also Kuwata-kun's ashes? After asking herself, Celes sighed sadly, "Poor. Obviously, yesterday was still a lively Sangtianjun, but that's all left......"

"Huh? You're a murderer, what are you crying here? Xiang of the Exterminator first put on a mocking attitude, and suddenly seemed to remember something, and pretended to suddenly realize and roared, "Understood! You must want to rub this powder on your face and body to keep your skin as white as ivory! What a terrible woman! ”

…… Speaking of which, it's a pity to rely on the fact that the family members were not killed by their own hands......

But Cyrus didn't get angry. She looked at Fukawa Fuyuko, and suddenly laughed, and asked while laughing: "I said ......"

Everyone watched Cyrus with bated breath.

"You stinking disgusting ugly garbage stupid pig girl who doesn't take a bath every day, can you shut your dog's mouth for me! I just don't want to be annoyed by a murderous madman like you! ”

Hibiko Kirikiri gave me a smile.

When Cyrus took a breath, I spread my hands and asked Kiriki Hibiki speechlessly, "Speaking of which...... This bag of powder, in addition to this bone residue, is the rest also ashes? ”
