"So...... Let's get back to the place where you asked about things," Hotaru nodded. Can you give us an overview of the relationships and things like that? Those soft messages that may be helpful in the case. ”

"Mr. Masao Moritomo, the teacher's assistant and team leader, his attitude towards the teacher has always been subtle - it is the kind that he is hired as an assistant, but he often asks the teacher to do something in a very rough way, and sometimes I even wonder which of the two of them is whose assistant." Gregory thought for a moment and then said.

"Then, probably that's what Shinichi Fujimura thought about Yoshiko Kamada, right? In other words, it is obvious that he has feelings for Yoshiko Kamada. If I'm not mistaken, Yoshiko Kamada and Shinichi Fujimura were supposed to be high school classmates, Yoshiko Kamada went to study archaeology in Canada, and Shinichi Fujimura began to organize amateur archaeologists associations as individuals. Later, after this event was organized, it seems that it was Fujimura Shinichi who strongly recommended that they take Yoshiko Kamada on this expedition, which added luster to her resume. ”

"To what extent...... If my impression is correct, there was a problem with the ice axe that Yoshiko Kamada bought locally at that time, and it was Fujimura Shinichi who specially exchanged his high-grade ice axe for Yoshiko Kamada, and used the new ice axe that she bought locally that was not easy to use, and the first time she used it, she broke a corner of the outer skin, revealing the core inside. Well...... In that sense, he's a bit pitiful. ”

"Lady Yoshiko Kamada didn't mean anything to respond to him?" Hotaru probably guessed the reason.

"Well, but there are more tragic things," said Grigory, with a very subtle expression. "Hmm...... If he knew, he would be crazy. ”

"She's getting along with Mr. Ito? Or......" Hotaru immediately made a rather immoral possibility, only to realize that if that were the case, Gregory would probably have used a non-trivial expression instead of the rather subtle attitude he had now. "Wait a minute, you're not going to have a big deal with her, are you?"

"......" Grigory was silent, and Hotaru's expression changed from initial surprise to half amazement and half appreciation (although it is a little strange for an 18-year-old girl to show the same appreciation for a middle-aged uncle in her forties as a newcomer, if you consider everyone's rank in terms of interaction...... Well, then Hotaru is indeed qualified to look at Gregory like this) and nodded. "Well, after all...... Later, she also said that she was not interested in the guy, and only came because it would help her studies. ”

"Okay," Hotaru continued to record with a slight smile. "That'...... Anything else? ”

The ice axe she bought there was a lot of hard work, and Shinichi Fujimura did a lot of funny things, because the one he used himself was a different kind of ...... Although it didn't perform very well, it felt very good, so he couldn't play with this icebreaker at all - but in the end, he found the remains first. ”

"Well, that memoir says that he found the first bones on the ground, and more were found nearby."

The conversation continues.

……

At the same time, the laboratory found something new.

"This abnormal bone crack on the cheekbone looks like it came from a very, very powerful punch," Chiba said, looking at the skull model as she looked at the gray plain. "If you hit it to this intensity...... I remember that the result of the previous investigation was that no one witnessed Henry Ito showing signs of injury, right? In other words, the wound most likely came from one of the chain of events that led to his eventual death. ”

"Beat it like this, or did he beat the bones like this before he died, maybe his facial tissue left similar marks, check it out?" Gray Plains lamentation.

"That face is dry, and the tissues inside have shrunk, and God knows how much it will recover after rehydration." Chiba is not very confident in such reverse work. "By the way, how are the results of the bone strength modeling over there restored?"

If the data on the bone density of the deceased can be called up, then the degree of trauma to the skull of the deceased can be used to determine the weapon used by the attacker, the force used, the angle, and finally the attacker. Of course, it is not impossible to make inferences with worse accuracy from the existing data, but ...... According to the current data from the physical engine run by Qian Yu with the computing power of the auxiliary unit, in the case of simulating the bone density of the normal 50-year-old Mongolian race, the force required to cause such a blow effect is about the same as the strength level that a normal woman can exert - but this does not mean that the murderer is the only woman in the expedition, because these data are all from the data of the Caucasian race, and the Caucasian race is taller and stronger than the race.

"We are still collecting data from other hospitals - and the examination of bone strength is basically to check the lumbar spine and thighs, and there are few skull bone density, so when the time comes, we can only reverse the above level based on the data below." Gray Yuan said this, signaling Qian Yu not to worry.

"Well, let's wait for the relevant stuff first...... Before that, should we go for some coffee? Qian Yu looked at the skeleton model and suddenly stopped, and said to Gray Plains.

"At work?" Gray Yuan frowned, looking at Qian Yu with the eyes of a sick person, only to find that his face was a little serious. "You...... Did you find anything? ”

"Let's go have some snacks first, and we'll talk about it later." Qian Yu shook his head. "Let's go, let's go down first."

……

[Ask as many questions as you can, and finally ask if he has ever had a physical altercation with Mr. Ito, such as hitting him in the face.] —Thousand Feathers

"......" Hotaru's gaze twitched for a moment, and then she restrained her gaze from looking at Gregory, and instead replied with a text message.

"What did you find?" Gregory noticed Hotaru's movements and asked.

"No, Fujiwara met a sex shop on the way back and asked me for my size so that he could buy me new props." Hotaru replied casually.

"Oh, yes, let me ask, which part of the prop did you buy this time?" Grigory asked, taking a sip of the water glass next to him.

"Later, he asked me how big the skewers were." Hotaru's response is very smooth.

Of course, Gregory wouldn't believe such nonsense - although he wasn't Japanese, he could still understand the input method, so what Hotaru was typing on the keyboard was no secret to him.
