To identify whether the footprints on the scene are forged, it needs to be analyzed from multiple angles.

First, when looking for tracks, not only pay attention to the texture and soil of the ground, but also weather conditions, the depth of the tracks, and where they actually came from.

Second, the target can be tracked by observing detailed features such as embedded objects, hairs, fibers, and textures in the footprint based on the size, shape, and depth of the footprint.

Of course, in this process, you also need to observe the angle of the footprint, namely:

Whether connected, diagonal or parallel, etc...

This is an important step in identifying and tracking where your goals are headed.

If the footprints are in the same direction and the regularity is obvious, it may be because the forger used the same tool when making the footprints, or traces such as sliding footprints appeared during the movement. At the same time, we should also pay attention to the position of the footprint on the ground, whether it presents a straight line, and consider key information such as the habit, height, and body shape of the turner...

Even if the faked cat tracks.

The cadres of a certain organization did not have the slightest carelessness.

I made up a reasonable excuse in my mind.

Ye Geng regained his composure and returned by the same route.

It's just... Although he made preparations, the follow-up facts proved that Dr. A Li and Takagi She had not made any inquiries including temptations at all in the face of his disappearance for more than ten minutes.

Phew... always staying with these careless guys, sooner or later, my vigilance will become low...

Ye Gengyi breathed out silently, feeling that the nerves that had been continuously oppressed seemed to be relieved a lot. First, he handed the mineral water to Dr. A Li, and then turned to look at Takagi She who was trying to tie the mouth of the garbage bag:

"did you find it?"

"Well, there's the paper cup that Police Officer Shiratori mentioned, but..."

Takagi scratched his head, "He called just now and asked me not to take it back to the Metropolitan Police Department to inspect the remaining beverage ingredients, and also asked me to buy a cup of the same beverage to compare the length of the wreath and the straw wrapper."

Visually, the lengths are the same... If you want to assume that the paper cups are damaged by unknown reasons after being discarded, the comparison is meaningless...

Ye Gengyi made a simple judgment, and after noticing that Dr. Ali's eyes also revealed a stupid clarity similar to Takagi Tsutomu, he said:

"It should be that Officer Shiratori tore off some as a souvenir. Assuming the cup has been replaced, it would be a waste of time to take it back to identify the ingredients."

"It turned out to be like this..."

Dr. A Li suddenly nodded.

Takagi said doubtfully:

"But... In this way, wouldn't there be no evidence?"

"There are also hats. However, with the eyesight of those children, it is not clear whether they made a mistake at the time."

Ye Geng paused for a moment, then changed the topic: "Doctor, it seems that they should reduce the time they spend playing video games in the future."

"Ah...this..."

Dr. Ali was a little embarrassed.

...Now if you say you want to play, won't you be reprimanded by Geng Yi for being disrespectful?

? ? ?

Takagi had a question mark on his head.

Why did the topic suddenly go to the level of education? Make that sentence clear!

He hurriedly walked around a few steps: "Ye, Mr. Ye... What did you say about the hat just now?"

"..."

Ye Gengyi was silent for a while, and then said:

"Although I haven't figured out how attractive that movie is, it can make the few of them who are only separated by an aisle ignore such a large movement of taking off and putting on their hats, but if that movie is called Kasakura The woman in that sea is the murderer, and it is very likely that she will prepare two hats and hand them over to a third person. Even if there is no assistance from others, she can find an opportunity to pretend to go to the bathroom after returning to the apartment, and throw the hat with the hair of Officer Shiratori on it. into the washing machine."

two hats?

…so what the **** happened to the hat?

Takagi's thoughts were not synchronized, and he couldn't keep up with the rhythm at all.

Ye Gengyi didn't bother to continue explaining, and opened the door of the beetle car:

"Doctor, let's go."

Regarding this case, all the information he has now is from Takagi Shepherd.

Therefore, for the time being, we can only think from the perspective of 'if Kasakura Nakai is the murderer'.

After all, the so-called 'stalker' police didn't have any clues, so I couldn't analyze it myself.

As for the method of forging the alibi so that the five little ghosts '12' could not see it with both eyes, how did Kasakura Nakai accomplish it...

Hmm... probably playing video games every day ruined my eyes.

Ye Gengyi used the tone of parents urging their children, and on the premise of safe driving, he said without squinting:

"Doctor, I'm a little busy recently, you...do you want to think about it, save the time you spend playing games and watching TV every day to study biology, and try to get another degree?"

Of course, it doesn't matter if you really can't get a degree, the important thing is to let the other party develop in this direction.

Little Rado still needs to study the antidote of APTX-4869, and once or twice it was fine, and she was pulled to do research every day. Even a doctor would definitely find something wrong after a long time.

And...that girl has too many worries, and she may not be willing to teach herself with her heart.

But the reverse is different. During the time when the doctor was studying biology, even if he had academic discussions with Xiaoda, he could pretend to be blind or deaf.

"Ah? Zengyi, what did you say?!"

Dr. A Li opened his mouth wide in astonishment.

Did you hear me right? Let yourself take another degree?

"Um…"

Ye Gengyi nodded slightly:

"Actually... this is my personal problem. I used to think that the skin and body will eventually decay, and only machinery can achieve relative eternity. Therefore, the understanding of biology is only at the relatively superficial level of medicine, and I have not studied it further. I think that as long as If you have made a breakthrough in the field of particles in physics, you can ignore this subject, and now it seems that both should be 'fine', at least start with 'knowledge'."

"But... I... I only know some simple pharmacological knowledge..."

Dr. A Li felt 'stressed', and began to stutter when speaking.

I am just a PhD in engineering!

If you don't count age~ lightnovelpub.net~ Usually when you meet a genius like Ye Gengyi who has nearly ten doctorates, you can only stand by and look up.

Do you really think everyone is as perverted as him!

"No rush, it's just a suggestion, doctor, please think about it." Ye Gengyi didn't force it.

People are past a certain age.

Learning cannot rely solely on external interference, but also requires one's own interest in that goal.

Moreover, Ye Gengyi asked Ali to study biology in order to save time, not to waste time and to stare at him and force him to work.

"Uh, huh..."

Dr. A Li said with a dry smile, "Then, let me think about it..."

Consider the next time you bring up this matter again and again, think of an excuse to politely refuse!
