This is a smell that Xiang Kun has never heard before. It is not a cat, a dog, or any other animal he knows. However, he is not surprised. After all, his "database" of odor is still limited, and it is basically collected in the downtown area.

What kind of animal is it?

Xiang Kun suddenly got a little curious, and when he was curious, he had to find the result.

He turned around, turned on the light of his cell phone again, took a branch and examined the body of the mouse.

There are a lot of insects on the body of the mouse, which can't be named to Kun. When the branches are moved, these insects flee in the light of the mobile phone. Some get into the grass, some get into the soil, and on the body of the mouse, there are a lot of small maggots crawling.

In the past, Xiang Kun would have felt numb and nauseous on his scalp when he saw this kind of scene, but now he doesn't feel much. He can even distinguish the smell of these insects and the sound they make when they move.

After checking, the mouse should have been dead for some time, but he did not know how to judge the exact time of death according to the degree of decay.

Xiang Kun sniffed it again. The smell that just made him feel strange was that the source should have already left. It was not here. The smell was not obvious and was about to disappear.

It's very likely that the source of the smell was the predator who killed the mouse.

However, what made him a little strange was that although the dead mouse was miserable, it did not lack arms and legs. It was relatively complete. After being rifled, it seemed that its internal organs had not been eaten. So, the animal that killed it simply looked bad at it, or was it slaughtered as a toy?

But the smell is neither a cat nor a dog. Besides cats and dogs, what other animal would do that?

Xiang Kun took a few deep sniffs, looking for the direction of the smell that attracted his attention, but after a few steps, he found that he could not find the direction of the smell.

Maybe it's too long?

Xiang Kun took his mobile phone and looked around the dead mouse carefully, checking the traces on the ground to see if there were any footprints left. However, he found that the battery of the mobile phone was running out and no useful information was found. Besides his son's footprints, there was no useful information - or information he could see.

Turn off the flashlight of the mobile phone, Xiang Kun sat down beside him, took a deep breath, relaxed his muscles, closed his eyes, let go of his senses, and continued to explore his surroundings with his sense of smell and hearing.

Xiang Kun is not only practicing, he is also looking for it.

He was very curious about the smell that attracted his attention. Even if he could not find the source of the smell, he hoped to find the same kind of smell in the mountain forest, and then follow it to find out what kind of creature left the smell.

The odor of each individual organism is different, and the odor of each biological group has its own characteristics.

The special smell just now, mixed with other flavors, is actually not obvious.

But when Xiang Kun was about to leave, he smelled the smell very accurately and was attracted by it. The smell was not in his "database", it was a smell he had never heard.

It seemed to be an instinctive response, as if the body was telling him to pay attention to the smell.

Xiang Kun has been sitting in the mountains until the sun comes out, five meters next to the dead mouse.

If you are an ordinary person, sitting in a mountain forest where you can't see your fingers in the big night, even if you are brave, you will inevitably feel uneasy and nervous. At least you will worry about insects crawling onto your body.

But although Xiang Kun closed his eyes, he couldn't see anything. He was very clear about everything in the area of more than ten meters. There was an earthworm digging in the soil, a worm was preying, a spider was weaving a web, and a few ants were marching in groups Oh, a beetle fell on his shoulder and flicked away.

Fortunately, mosquitoes have no interest in him, and have not been bitten since the mutation.

All night, Xiang Kun didn't wait for the smell to appear.

Of course, sitting there, he couldn't search the whole mountain with smell and sound, even though it was very small.

So he got up and began to search the mountains.

The reason why he didn't do this last night was that although his hearing and smell were far beyond ordinary people's, he had no problem walking in the familiar streets with his eyes closed. However, on the mountains where there are no roads, he is expected to hit a tree or step empty within a few steps.

In the morning, Xiang Kun searched the small hill.

At 1:00 p.m., he finally left, ran back home, changed his clothes covered with various stains, took a bath, and went to the largest zoo in the city.

Xiang Kun has always been unable to let go of the smell. He always attaches great importance to the "signal" given by his body, even if the "signal" is not obvious, because it may help him understand his body better.

So he came to the zoo, of course, not to entertain, but to enrich his "database.".

He wanted to see if there was a similar sample of the smell in the zoo.After buying a ticket from Kun, he went in all the way without missing any of the houses and cages to collect the smell of each animal.

Even if some animals have been shrinking in the museum and not appearing in the activity area outside for tourists to watch, it does not hinder Xiang Kun from "catching" their smell.

It was not until 6:00 p.m. that Xiang Kun could distinguish the smell of all the animals in the garden.

But unfortunately, it didn't belong to the same kind of special smell that he smelled last night.

This makes Xiang Kun more curious.

After returning home, he took a flashlight and went to the mountain again to find the dead mouse accurately.

It was more than 8 o'clock in the night. Xiang Kun, with a flashlight in one hand and a small stick in the other, carefully checked the dead mouse again.

Although the degree of decay was more serious, Xiang Kun still found two penetrating wounds, looking like they were penetrated by claws?

It's just that claw is as thick as his index finger, right?

Big cats?

But it's not right. In the zoo today, he has smelled all kinds of tigers, leopards and lions, and the smell types are not correct.

Moreover, this is not a deep mountain, old forest or undeveloped area. There can be no wild animals like that. At most, there are wild cats and dogs.

If there is a large predator here, there will not be only one dead mouse. There should be more traces and it is impossible to find them. What's more, there are no footprints left on the edge of the dead mouse, which is unreasonable.

Xiang Kun searched around the hill and the lake all night, but he still found nothing or no trace of the smell.

After daybreak, he went up the mountain again, centering on the place where the dead mouse was, and searched around again. Until more than five o'clock in the afternoon, there was still no clue and no sign of any beast on the mountain.

Xiang Kun also began to feel that he was a little too paranoid?

Maybe the smell, in fact, is just because it is about to dissipate, and I don't have an accurate judgment. What about the smell?

When I went home into the corridor, I met Miss Yang, who was keeping husky, walking out of the elevator. She frowned tightly and seemed to be anxious.

She did not reason to Kun, Xiang Kun naturally would not say hello, two people as if did not see each other, brush past.

However, when Xiang Kun pressed the floor in the elevator, Miss Yang suddenly turned around and blocked the elevator door.
