Coroner Coroner

Yuan Shan and Ye suddenly became nervous:

A peeping shadow suddenly appeared in this gloomy forest, which was enough to be called a terrifying thing.

Especially, in this mountain where a perverted murderer has just been caught.

She couldn't help feeling a little nervous:

"Mr. Lin... Then, who is that?"

Lin Xinyi didn't answer, but muttered secretly in his heart:

"You don't even dare to show your face, really..."

"As for being so reserved?"

"Both sides are like this, and they don't say anything in their hearts, alas..."

He sighed helplessly.

Yuan Shanhe Ye's big eyes were filled with puzzlement.

Then, without knowing what he thought of, a meaningful smile appeared on the corner of Lin Xinyi's mouth:

"Miss He Ye, don't you want to learn criminal science and technology from me?"

"Just right, I can teach you now."

"What do you mean?" Yuan Shan and Ye were a little puzzled.

But Lin Xinyi had already pulled out his flashlight, and chased after the black shadow in the direction where it disappeared:

"Go, come with me."

"I'll teach you how to use the power of trace inspection to find that guy who dared not show his face!"

Chapter 293 Tracking and Anti-tracking

Lin Xinyi did not chase after the black shadow that had disappeared into the jungle in a hurry, but took out the flashlight in his arms and illuminated the ground that the black shadow had just stepped on.

As for the blazing beam of light, he began to observe carefully.

"Mr. Lin?" Yuan Shan and Ye approached curiously: "What are you looking at?"

She also looked at the ground following Lin Xinyi's gaze:

The ground was covered with a thick layer of dead branches and leaves, and as far as the eye could see, there was only a piece of withered yellow, and there were no footprints left by any black shadows.

"I don't even have any footprints, how can I track them down?" Yuan Shan and Ye were a little puzzled.

"Of course there is a way." Lin Xinyi smiled: "Feihong treads the snow, and geese leave traces. As long as someone walks through here, it will inevitably cause certain changes to the landscape and leave corresponding traces."

"For example, in this forest..."

"People stepping on fallen leaves do not leave clear footprints."

"But the dead leaves are as light as paper, and the layer of dead branches and leaves piled up can't bear the weight."

"A person's legs and feet are like an 'iron plow'. When they land, they will be deeply embedded in the dead leaves, and when they move, they will inevitably lift some leaves from the ground, causing the dead leaves to visibly 'turn'. .”

"And in this inaccessible place, under natural conditions:"

"The outermost surface of the litter layer is the newly fallen branches and leaves, showing a withered yellow color, and the original shape is still recognizable."

"Beneath the surface layer of undecomposed leaf litter is a layer of semi-decomposed, coarsely humusized litter."

"The fallen leaves in the middle and lower layers have been partially decomposed, the color is black and green, and the leaf structure is not complete."

"so…"

Lin Xinyi pointed to a few inconspicuous black and green leaves on the ground covered with fallen leaves, and explained to Yuanshan Heye:

"Where there are such black and green leaves appearing on the surface of the litter layer, that is where the prisoner has been active recently."

"These black and green fallen leaves that have been trampled and flipped to the surface are the best signs that can help us track criminals in the forest."

"So that's how it is..." Yuan Shan and Ye heard it clearly: "As long as you find these black and green fallen leaves, you can know which direction the prisoner is fleeing to!"

Her pupils quietly brightened a little, and her expression became more focused.

He and Miss Ye were not interested in reasoning before.

I want to study forensic medicine just to have more common topics with my future boyfriend.

But things are a little different now than before.

In the past, she could only play the role of a bystander in the case, and she could only hang up the phone and act as a vase, watching Hattori Heiji show off her reasoning there.

Just standing on the sidelines and watching others play the game, of course you can't experience the real fun of the game.

That's why Yuan Shan and Ye didn't like reasoning all the time, let alone choose a career like detective or policeman as their vision in life.

But now, under Lin Xinyi's leadership, she is personally participating in the game as a "player".

And the reasoning game that Hattori Heiji is good at is like Black Soul, which makes those "handicapped party" want to play along, but they can't play it at all.

In contrast, Lin Xinyi is like a quest elf in a third-rate skin-changing mobile game who can automatically find his way. As long as he has a normal IQ and is willing to listen carefully to what he says, and follow along honestly, there is nothing he can't learn.

"Learning this knowledge seems to be very interesting..."

He and Ms. Ye faintly realized the joy of criminal investigation and the work itself.

She began to follow Lin Xinyi, and under his guidance, she carefully searched for the black and green fallen leaves that had been turned over by the "prisoner" on the ground.

In this way, following the black and green fallen leaves, the two walked through the woods all the way.

"It's quite able to go around in circles..."

"This guy, is he so afraid of being peeped here..."

Lin Xinyi couldn't hold back and muttered a few words in a low voice.

That "black shadow" seemed to know that someone was chasing after him.

So he didn't run straight out of the woods.

Instead, he did the opposite, took a long detour in the woods, and prepared to return to the climbing path in a detour.

The other party tried to get rid of their tracking, so that they would not find out who the voyeur was.

but…

"Do you still need to think about this question?"

Lin Xinyi sighed helplessly in his heart.

He also couldn't help but reminded Yuan Shan and Ye who were following closely beside him:

"Miss He Ye, who do you think is the person who is spying on us?"

"This..." Yuan Shan and Ye lowered their eyebrows in thought, and their expressions gradually became serious: "Could it be Director Kakuda and his accomplices, who were in ambush here after the incident, waiting for an opportunity to retaliate against us?"

Lin Xinyi: "..."

I can think of such outrageous answers, but I just can't guess the correct answer.

Speaking of which, the great detective is also... so much effort to escape, I don't even think about it, who else would come here to peep here besides him.

It's so slow to talk about feelings.

No wonder you have known each other for more than ten years and are not sure about the relationship...

"never mind…"

Lin Xinyi gave up the idea of ​​directly revealing the answer.

He still decided to let Yuan Shan and Ye find out the voyeur with their own hands, and let her determine for herself what that guy was thinking.

Therefore, Lin Xinyi kept silent, and led his new student to circle around with the "prisoner".

Soon...

They came out of the woods and came to a stream.

There is a small stone beach beside the stream, on which are piled up several large rocks covered with moss, and a dense layer of small gravel.

"The prisoner just walked along the stream, stepped on this rocky beach and walked to the left."

After a little observation, Lin Xin came to a conclusion.

"Is it because of the footprints on the rock?"

Yuan Shan and Ye were not slow to react.

Because the moss on the rock has obvious slip marks, even a rookie like her can see it at a glance.

"The slip marks are bright green. Compared with other dark blue mosses, they should have just formed."

"The prisoner did walk through here."

"However, Mr. Lin, how is this direction determined?

"It's very simple." Lin Xinyi began to speak in a calm manner: "Just try to walk on a mossy rock and you will know:"

"If there is a footprint scratch on the rock, the direction in which the tip of the scratch points is the 'back' of the advance."

"However, in fact, the single footprint on this rock alone cannot determine the direction of the prisoner's escape with certainty."

"After all, the volume is too small to explain the problem."

"The prisoner may change direction later, or it may be that he deliberately forged it."

As he spoke, Lin Xinyi pointed to the small stones covered by the stream:

"To really confirm the direction of the prisoner's escape, you have to look at the strings of footprints on the gravel ground."

"Eh..." Yuan Shan and Ye took a closer look: "Are there any footprints here? Why can't I see it..."

In her eyes, the rocky beach was nothing but stones, and there were no traces on it at all.

"You can see it if you look closely."

"Although the gravel ground is not easily deformed, it is difficult to leave clear footprints."

"But the weight of a person is still enough to move these small rocks and create cracks next to the footprints."
