Overturned Tower

All members of the executive department who were still crowded in the room were gone in the blink of an eye.

Except for Russell and Ringo, there was not even a living person in the house.

Even the corpses in the dust gap were not buried... The moose man with a bent neck remained stuck in the bathtub in this posture, as if practicing holding his breath, immersing his face in the dark red blood. middle.

"...Mr. Ultramarine?"

Being in the same room with the strange-looking "suicide" corpse, Ringo couldn't help but be a little scared.

She stood closer to Russell, looking around as if nervous, as if sensing the sight of the underworld: "Are we still going to...continue to investigate?

"The execution department said... Mr. Chenzhao committed suicide. I think it's meaningless even if we find out anything...

"They obviously just didn't want to take care of it! He was shot eight times in the back and twice in the back of the head. How could it be suicide? Are you listening?"

Ringo murmured in a low voice, but saw Russell staring at the corpse intently.

After a while, Russell suddenly said: "He is 1.8 meters tall and thin. He lacks arm strength and walks very steadily."

"What?"

"After calculating the trajectory of the bullet mark, the position of the muzzle can be calculated. Although there are no footprints, the approximate size of the opponent can still be calculated. If there are footprints, by calculating the size, center of gravity and stride of the footprints, I can also directly give the prisoner Modeling.”

Russell stared at the void in front of him and said casually: "When I was in school, I quite liked doing bullet scar calculations. The execution department of Sogo Island sometimes gave me some cases for analysis and modeling. Some unsolved cases, It gives me the feeling of playing a hard-core suspense reasoning game, and I feel a sense of accomplishment when I solve the puzzle, which is very interesting."

"Game...?"

Ringo opened his eyes slightly.

She also knows about "Bullet Trace Analysis", which is also a subject required in Nephthys University.

During her undergraduate study, she had only mastered a little bit... But just looking at those dense formulas and data, Lin Ju felt his scalp go numb - even if the specific calculation steps could be left to the calculations on Kongdao. The center, however, the center that only provides computing power is not intelligent enough to directly see what happened in the past like going back in time.

Confirming useful data and selecting formulas must be done in person. After getting the initial data feedback, it will be even more difficult to propose various possible steps through irrational deduction...

Unless the deceased remains motionless after being shot - whenever he moves, even if he just turns around, the scene must be "initialized" in his mind. If the initialization is not precise, the final intersection point of these bullet marks may be very bizarre.

Either fly directly to a height of more than five or six meters, or bury it directly in the soil. If you don't die immediately when you are shot, but you have steps to move and avoid, you may even be able to analyze the bullet marks caused by a gun into seven or eight people; or it may be possible to analyze the gunman while jumping left and right around the victim. shot.

And the biggest problem here is... considering the existence of psychic energy, those outrageous analysis results may actually be true. Therefore, a clear bullet mark analysis report can not only lock the number, size and other data, but also determine whether the opponent is a psyker who can form a special shooting angle.

This also leads to a problem - that is, you cannot directly infer that your calculation is incorrect through "the result is obviously unreasonable". That unreasonable result may actually be the truth.

This is a more difficult subject than advanced mathematics... It would be better to say that advanced mathematics, a subject that the mathematics department disdains, is not worth mentioning in front of bullet scar analysis. The amount of calculations required on the level of complex dynamic systems and real variable functions can be compared with the ultimate application subject of bullet scar analysis.

And this subject that tortured countless students, including Ringo, was just...an interesting game in front of Russell?

This is like someone saying very naturally, "The real variable function is quite interesting, I just play it as a game".

——What kind of monster is this?

Although Ringo knew that Russell was excellent from the beginning, it was not until this moment that she truly realized why Russell was so good that he was targeted by the elf director...

“It’s really a pretty hardcore game.”

Russell nodded, stared at the void in front of him, and at the same time said calmly: "Look, we can only use the bullet holes and reversely calculate the bullet marks. This is the essence of modern technology. And after that, we can also By simulating his position before death and simulating his actions after being shot, the details of the crime scene can be directly determined, or like now - the specific data of the prisoner can be directly locked.

"You see... we can calculate that although Chen Gap struggled after being shot, he had no intention of escaping. After the first five shots were fired, it took a while before the sixth shot was fired, and something happened on the way. What?

"If it was forced interrogation or torture, there was no sign that Chenxiao's head was lifted out of the water. There were not even fresh fingerprints left on his body. So I speculate that he should have been shot five times before being shot. A physical link was forcibly used to input or output something from his brain.

"Considering from this point of view, the sixth shot may be the real purpose. For example... to destroy evidence.

"When we calculate his last position before death, combined with the depth of the bullet hole, we can calculate the kinetic energy of the bullet. Then we can determine that he was not pushed into the pool by the impact after being shot, because that small bullet simply cannot There is no such kinetic energy. He was at least half a meter away from the bathtub. Therefore, when he was hit, he should have actively jumped towards the pool - Ringo, let me test you, what does this mean? "

"...What does generation represent?"

Ringo's voice suddenly became weak.

It was like dreaming back to a high-level mathematics class in college - it was like being drowsily distracted and suddenly being called upon by the teacher to stand up and answer a question.

That strange yet familiar fear made her silent for a moment.

"Ringo?"

Not hearing her reply, Russell frowned slightly and turned around: "Whatever you want to say, just say it. I'm not your teacher, what are you afraid of?"

"On behalf of..."

Ringo tentatively replied with some stumbling: "On his behalf... did he commit suicide?"

As soon as she said these words, she realized her stupidity and realized that she had said the wrong thing.

She quickly tried to make amends, trying to restore her image in Russell's mind: "I mean, this probably means... that he actually knew that he was going to be shot? Did he do it voluntarily?

"...No, no, I mean..."

"You're right, what are you afraid of?"

Russell glanced at her strangely.

Ringo breathed a sigh of relief, but was still a little dazed: "Ah, that's good... eh...? Am I right?"

"yes."

Russell nodded: "He exposed his back just so that the man could aim.

"After being shot, I also leaned forward so that my body could accurately fall into the water instead of falling on the same spot... as if I was afraid of accidentally soiling something.

"He died in the bathroom probably because it could block the sound of gunshots and wash away the blood - even if he was close to the bathtub and fell down immediately after being shot, there should still be blood where he was shot. But the ground is so clean, there are no traces of anything... There can only be one explanation for this, and that is that it has been washed away. And this was before the blood dried.

"Then the situation is clear."

Russell said, looking at the shower head next to him: "He was shot to death while driving this thing. The sound of water blocked the sound of gunshots and screams, so he was not discovered by the neighbors.

"When we came, although there was still moisture here, the water had stopped long ago. That means that the second person closed it when he came. The time in between was enough for the water to flow. The blood on the ground washed into the sewer.

"——Even if the shooter was not Chen Gap, he must have the will and consciousness to die. From this point of view...

"This might really be called suicide."
