Chapter 137 The police dog knows the way

The next day, in the afternoon, in the mountains far away from the city.

Lin Xinyi held a forensic investigation box in one hand and a big dog in the other.

Mao Lilan held a field survey box in one hand and a Conan in the other.

The two walked side by side among the luxuriant forests, but they didn't look like leisure tourists who came to the mountains for a party, but a professional team who came to investigate the autopsy.

They didn't say a word, their expressions were serious, they just walked in the forest silently.

Finally, Conan couldn't help breaking the silence:

"Sister Xiaolan, are we lost?"

"Hmm..." Mao Lilan, who had been in charge of reading the map and guiding the way, smiled awkwardly, "No, no way? The villa should be nearby."

"Yeah...but we've been wandering around the woods for almost an hour."

Looking at the verdant forest in front of him that seemed to never end, Conan sighed helplessly.

"Ahem...I'll call and ask Yuanzi."

"Conan, help me lift the box."

Saying that, Mao Lilan let go of Conan's hand, and put the on-site inspection box into Conan's arms by the way.

The reconnaissance box was so light that she couldn't feel the weight at all, but it was as heavy as a stone in Conan's hands with small arms and legs.

He staggered abruptly, and managed to stabilize himself.

"Really...why bring something like this to a party."

Conan held the survey box in his hand vigorously, and while Mao Lilan was making a phone call, he quietly approached Lin Xinyi:

"Hey, Lin, is there something you're hiding from me?"

"Just for the party, why bring a scout box and Caesar?"

As he said that, he couldn't help but glanced at that big black-backed dog squatting obediently beside Lin Xinyi, sticking out its pink tongue:

Conan knew that this dog was the ace police dog of the forensic department and a well-established national civil servant.

How could Lin Xinyi, who is so good-looking, use a male dog for private use and take Caesar out for a trip?

So, in Conan's view...

He must have grasped some important unknown clues, so he came here with them in such a fully armed "tour".

"Didn't I say that...I don't have any clues here."

"Bring the dog and equipment here, just worried that someone will be killed by you again."

Lin Xinyi explained again to this over-curious detective with some helplessness.

What he said was the truth, but Conan, who had no self-knowledge, always felt that Lin Xinyi was hiding something from him.

Conan, who was full of curiosity, wanted to cling to Lin Xinyi and ask questions.

Mao Lilan on the side was holding a mobile phone, and walked over with a embarrassed face:

"No, the location in the mountains is too remote."

"There is no signal on the mobile phone, and the call cannot be made."

"Don't worry, look at the map more, you should be able to find the way."

Lin Xinyi's tone was very calm, but he was sighing softly in his heart:

The barren mountains and mountains without even a mobile phone signal... This is simply an excellent place to commit crimes.

Coupled with Conan, the lone star of the gods, I am afraid that people will really die today.

If so, did the murder happen already?Do you still have a chance to stop it?

Lin Xinyi was silent while Mao Lilan was looking at the map seriously.

After Conan boredly observed the surrounding environment, he found some clues that could help them find their way:

"Look, there are several strings of fresh footprints on the muddy ground over there—"

"No one usually comes here, and the footprints should be left by those who arrived at the villa before us."

"Follow these footprints, and you will most likely find the villa in the mountain."

As he said that, Conan walked to the front and followed the footprints to guide everyone.

Lin Xinyi, Mao Lilan, and Kaiser followed closely.

But not long after the group walked, the dirt road turned into a stone road, and the footprints could no longer be seen with the naked eye.

And there are several forks in front of the stone road, without footprints to guide, making it difficult to choose the direction.

"Let me look at the map." Mao Lilan dazedly picked up the complicated and difficult map.

"Since Yuanzi and the others walked this road before us, they should have left some clues."

Conan carefully observed the various details at the fork in the road, trying to use reasoning to judge the correct direction.

And he hadn't had time to start reasoning...

Lin Xinyi gently tugged on the dog's leash, and let the big black-backed dog beside him stand up:

"Let Caesar come."

"There's also a human scent on the footprint."

"If these footprints were really left by people who went to the party at the villa, then Caesar would be able to recognize the way."

"Wang Wang Wang!"

Hearing Lin Xinyi calling his name, Caesar responded immediately.

It grinned its fangs, pricked up its ears, and wagged its tail. When it was leisurely looking at Hanhan, its eyes suddenly became sharp, and it entered the standby state in an instant.

"Miss Maori, it's just right, come here and review the relevant knowledge points about the source of footprints and smells."

"There are several footprints here. Which footprint do you think is better for police dogs to track?"

Leading Kaiser to the muddy field with footprints, Lin Xinyi did not forget to teach the students.

"Which footprint is a better source of smell?"

Seeing Lin Xinyi suddenly arrange "practice training", the studious Mao Lilan also became energetic.

She put down the map, came to Lin Xinyi, squatted down with Lin Xinyi, lowered her head and studied the footprints on the ground.

Although the distance between the two is not close enough to cause physical contact, it is definitely not far away.

Seeing this scene, Conan suddenly lost the mood to reason.

It's like seeing your own tender cabbage being picked up by other pigs...

Holding back his unattractive little face, he squeezed abruptly between Lin Xinyi and Mao Lilan.

Conan, who graduated from Hawaii and knows everything, wants to use this method of building a "border wall" to completely separate his childhood sweetheart from potential rivals.

But this "border wall" hasn't been built for long...

"Conan, don't block me from talking to your new brother."

Mao Lilan mentioned it lightly, and carried Conan out.

"Sister Xiaolan..." Conan still wanted to be cute, so he stayed.

But Mao Lilan was like Kudo Shinichi who encountered the case, staring at the footprints on the ground with a focused expression, completely indifferent to him.

Conan was helpless for a while.

There is no way, Xiaolan, who was originally gentle and virtuous, has become a "reasoning maniac" obsessed with solving cases.

Conan had no choice but to try to stand on the other side of Lin Xinyi, thinking of pulling the rival out further.

But unfortunately, Lin Xinyi's position on the other side was being occupied by a big dog twice the weight of Conan.

"Wang Wang!"

Caesar bared his teeth at the imp who squeezed over in displeasure, indicating that the position had been taken by a dog.

Under the disgust of others, Conan finally gave up struggling completely.

And in his sullen and resentful eyes...

Mao Lilan stared closely at the footprints on the ground, and began to analyze methodically:

"I remember Mr. Lin, you taught me...the smell in the center of the footprint is mainly from the sweat secreted from the soles of the feet."

"Part of the odor molecule diffuses outward through the upper and the upper, while the other part slowly penetrates into the deep layer of the sole, and slowly penetrates the sole to reach the ground."

"So, depending on the material of the sole, the time it takes for the odor molecules to reach the ground will also vary."

As a serious student, she recalled the knowledge Lin Xinyi taught verbatim.

Then, under Lin Xinyi's encouraging and admiring eyes, Mao Lilan continued to analyze:

"In these shoe prints..."

"There are two groups of shoe prints that show more and more obvious traces of knocking, digging, digging, and twisting, and the front palm moves forward under heavy pressure, and the heavy pressure points and arches are not clearly reflected-it should be leather-soled shoes."

"The other sets of shoe prints are relatively complex, with complete footprints and clear gait characteristics. They should be rubber-soled sneakers with better toughness and elasticity."

"The odor penetration of leather-soled shoes is better than that of rubber-soled ones, so if you want to choose a highly recognizable police dog smell source, you should choose from the shoe prints of those two pairs of leather-soled shoes."

"In the shoe prints of these two groups of leather-soled shoes, there is a pair of small size, narrow toe, deep pressure surface on the forefoot, obvious load-bearing, and a long distance between the pressure surface of the back palm and the forefoot. Help with sneakers."

"The uppers of these shoes are too high and the soles are too thick, which is not conducive to the penetration of odors."

"So, exclude the shoe prints of this group of women's leather shoes..."

Pointing to one of the many shoe prints, Mao Lilan confidently gave a conclusion:

"It's best to choose the shoe print of this men's leather shoe, and use it as a source of smell for Caesar!"

"Exactly."

Lin Xinyi nodded in satisfaction, and gave the student full marks in his heart.

Being able to apply the knowledge in the book to practice shows that Mao Lilan not only memorized the knowledge in the classroom, but also spent a lot of time after class to carefully observe and study the actual shape of various footprints.
