The next day, the reception room of the Tokyo branch of Sindora.

"This thing...... Are you sure you have no problem using it? "Hoshino Kaede's confidence is not very strong." Although this thing can simulate real conditions in the strict sense, it is virtual after all......"

"No problem, no worries." With that, Qian Yu leaned back on the sofa and knocked on his chest seemingly casually.

"Oh......" Kaede Hoshino immediately understood, and his tone widened. That's okay, we're all covered. So, shall we start the simulation here? ”

……

More than three months ago, Sindora released its groundbreaking simulation game system "Cocoon", in which a groundbreaking game engine was installed to help gamers experience extremely realistic realism.

And what Chiba wants to borrow is the game engine of [Cocoon] - they hope to use this system to simulate the ice crevasse where the corpse was found at that time, and analyze the state of the corpse in its whereabouts. Even if the state of the ice crevasses may be different from 20 years ago, at least the fractures can be analyzed to find out the order of the breaks, and to see if the order of some wounds does not match the order in which they should have been created during the fall.

Of course, this system has never been used in the criminal investigation work of any country, and even any tentative argumentation has never begun, which is why Hoshino Kaede has some concerns about this. But Qian Yu didn't need to care about this—just like the implication of the action he had just tapped his chest, he just needed an excuse to get his auxiliary unit involved in the computation and improve the efficiency of the analysis.

Or if we evaluate it with a pessimistic view of the current level of computing, the intervention of the auxiliary unit is almost impossible to describe this matter: after all, if Qianyu did not let his auxiliary unit intervene in the calculation work in any of the identification work, then all this would be impossible at all.

Although the foundation of the entire physics engine has been laid out in the professional methods of Hiroki Sawada from the next century, it is precisely because of this element that most of it must be disabled if today's computers want to run smoothly. Even Sindora's own high-level computer in Tokyo would take a long time to complete a simulated drop analysis with most of the physics turned on. If you want to finally find a way to fall that exactly matches the fracture marks on the corpse, the final time may be measured in days or even weeks.

[It is precisely for this reason that these jobs are just for show] - Qian Yu thought as he watched the programmers enter the data into the computer one by one. Because when the computer has not yet obtained all the required data, he has already sat next to a computer connected to the central data center, accessed through the data transmission port to obtain the right to use the physical engine, and used the auxiliary unit to borrow the relevant data from the game engine of the cocoon - the computing power of his auxiliary unit is far stronger than the computing power of the cocoon, and he cannot complete this job himself only because he does not have a physical engine in his hand that can be used for simulation work.

Analysis revealed that there were indeed anomalies on the corpse's body: some of the wounds on his cheekbones did not fit the normal environment of falling, and the cracks in the cheekbones prevented the extension of other cracks and breakage marks, indicating that the injury was in sequence ahead of the others. And if this is caused by hitting a bulge in some ice crevice during the fall after being thrown into the ice crevice, then the obstacle caused by hitting the cheekbone will inevitably deform the falling corpse, and the weight of the human body will cause damage caused by strong external force on the cervical vertebrae.

But now, only more serious compression fractures have been found in the cervical and spine vertebrae, like the scars caused by the corpse being stuck in the ground like a javelin, but no other fractures have been found that can match the conditions of the scars on the cheekbones.

Since the scar on the cheekbone did not come from a fall, what could it have caused?

"Well, then, we need to input this data for a while, and then we need to debug the program, why don't you go back first?" Seeing that Qian Yu had probably begun to think, knowing that the other party had already obtained the result, Hoshino Kaede asked.

"Ah, yes, then...... Thank you for your hard work, we will go back and wait for the results of your calculations! ”

At the same time, Hotaru is conducting other investigations on the other side.

……

Teidan University, outside the auditorium.

"Shinichi Fujimura, if the information is correct, he should give a lecture here on 'Perseverance and Spirit of Archaeologists......" Hotaru said as she looked at the sign outside the auditorium and then at the printed paper version of the online bulletin in her hand. Well, the time is over, and now it might be Q&A time? But this question is inevitably too long, right? ”

Standing in the doorway of the hall of the auditorium, Hotaru looked in a little and saw that Shinichi Fujimura was still encouraging a student who was asking a question, while the other students were listening rather attentively - no, not just the students at school, as Hotaru had also seen some traces of high school students wearing Teidan uniforms.

"Ahh But seriously, this kind of chicken soup for the soul speech that is not materialistic at all is simply junk chicken soup that only needs to talk about those empty words," Hotaru pursed her lips. "It's almost impossible to say the wrong thing in this kind of lecture, because you just have to talk nonsense all the time. In contrast, nutritious lectures don't seem to be so popular with the general public. ”

And just as she was muttering this, many students suddenly got up from their seats and walked in the direction of the gate where she was. There was no doubt that the speech was over, and she could go in and ask Shinichi Fujimura about it.

"'Shinichi Fujimura, who is full of enthusiasm, wishes Reiko-san who has the courage to pursue her dreams.'" Okay, you're done...... Don't squeeze or grab, each of you has a share! Shinichi Fujimura smiled and signed a copy of his book, signaling the schoolgirls who surrounded him to relax. I'm already tired, so it's impossible to muster up the energy to speed up desperately, give me a little time to sign slowly, I promise to sign everyone! ”

At this moment, he inadvertently saw a memoir he had written about Henry Ito's team in Canada 20 years ago, standing not far away, looking at him with a smile on his eyebrows.

"Oh well, I'd better hurry up and sign everyone's names, don't delay your time!"

Looking at Shinichi Fujimura, who suddenly became energetic and took the opportunity to return the book from time to time, Hitaru's smile became even brighter.
