"Alright, they're out, let's get on with the adults," Grigory said as he looked at the departing Chiba and took over the conversation from Fujiwara. "Hmm...... Let's start with the wound you mentioned earlier, that you didn't understand. Do you think that when you eat people, there is no need to go specifically to the opponent's foot knife? ”

"Isn't it?" Fujiwara asked rhetorically. "When eating people, shouldn't we mainly use the place where there is meat as the place to cut the knife, and what to do when you waste time and energy cutting in the kind of place where there is no meat?"

"Hmm......" Grigory raised an eyebrow, and then asked a somewhat puzzling question. You...... Have you ever eaten someone? Have you ever eaten someone with whom you have a good relationship? ”

"Of course not, what do you want to say?" Fujiwara's brow twitched.

"When you're so weak that you can't find something to eat, and the only available source of food is your recently dead friend, you're going to have to eat them. It's painful, but it's better than everyone dying together. Grigory shrugged. U****takeably to the fast waning strength and energies of the starbing survivors.” (There is no doubt that the strength and energy of the survivors of hunger are rapidly declining – 1965, Stackpole)

"And when you want to eat the flesh of a whole corpse, you can't keep your mouth shut, as long as you don't get too mad - it's your good friend, after all, his face is right in front of you, as if he had just fallen asleep, and maybe even in a state of dead rage. And you're going to tear a piece of meat off his body and eat it? I think even if the court would forgive you, your conscience would never be at peace. So, in order to solve this step, a necessary means for those who are struggling mentally is ......"

Grigory turned a section of the cervical vertebrae on the dissecting table, showing Fujiwara that he had given him a chance, but no sign of his discovery. "See this? When you just gave me a picture describing the dismantling of the shoulder joint, you swept it here, and the picture was clear enough, but you didn't know anything about it. ”

The atlas vertebra (first cervical vertebra, C1) is a ring-shaped bone that resembles the shape of a drawn bow and arrow, and on the body of this "bow", a small cut is clearly visible.

"This ......" Fujiwara's face was a little embarrassed,

"I thought you'd be able to find out about it, so I'm a little disappointed that your report didn't mention it at all." Gregory reprimanded Fujiwara solemnly. "Next time, I'm going to search for these bones carefully - this cut mark is highly homogeneous with many of the marks you just mentioned, and if you actually look at it, you will definitely be able to realize the meaning of this trace, understand?"

"Yes."

"Okay, now that there's a cut here, tell me," Grigory nodded, before returning to the subject. "What is this knife for?"

"In order to cut off the head of the deceased, disintegrate the perception of the other party's identity, and facilitate his subsequent actions?" Fujiwara said thoughtfully.

"Well, I think that's the first step – if you do want to cut something, it's not just to cut off the meat for cooking, but to remove the features that indicate the other person's closeness to you." Grigory nodded. "Eating one's own family member or friend is unacceptable to most people, so they have to find a way to ignore it."

"So, what about the cuts on the hands and feet?" Fujiwara asked again. "Is it for ......?"

"It's pretty much the same, it's all about removing concerns. But strictly speaking, it should be said that it is different," Gregory was pleased with Fujiwara's extrapolation. "I don't think it's about forgetting that it's your friend—it's hard to remember who it is with just one hand unless you've seen and understood it very closely. If you use knives in these places, in fact, the main thing is to make them not think that this is a human hand, but more like a ...... Delicious barbecue legs. ”

"Is there any difference between the two?" Hotaru asked. "Is there any essential difference between finding a way to ignore that this is your friend and finding a way to ignore that this is a person?"

"Generally speaking, no, but now there is a difference." With that, Grigory motioned for Fujiwara and Hotaru to take a closer look at the incisions in their necks and finger bones. "You look closely at these two cuts, and then look at the cuts on the shoulders and legs, and see if there's any difference between them."

......After looking at it for a long time, Fujiwara frowned slightly, as if he had found something...... Seems like the type of notch on these things is not quite the same? I mean...... It feels like the types of these nicks don't seem to be the same, and it doesn't feel like they belong to the same pattern. You see. This mark on the arm also has marks on the shoulder and head, and the aspect ratio is unusually high compared to other marks, and it is not particularly deep, but particularly narrow - clearly from a very high-quality cutting tool. Wait a minute, do you mean to say-"

"Well, because they obviously didn't make it with the same tool," Grigory nodded. "These are deep and narrow, probably caused by some professional saws: if you look closely at the cut marks on the shoulder blades, you will see that there is a cut that does not cut the shoulder blade completely, but only half of it. Unlike a normal knife cut, part of the bone is worn away by the cutting action – meaning that the marks are repeated by a tool...... Produced by a see-saw action. ”

With that, Gregor used his palm to simulate the blade of the saw, simulating the figure-eight cutting trajectory of the saw. "Look, is this possible to create a mark on this half-cut shoulder blade? If it were a normal action of cutting meat to the bone, it would not have this strange shape. ”

"Why do you want to cut these parts with a saw, but use another tool to cut your hands and feet?" Hotaru was puzzled.
