Lin Shuo and the three of them soon returned to the foot of the mountain peak where they slept last night.

This mountain, before being A

e I could hear that there was a crypt underneath.

Can be the entrance to the crypt, A

I heard it, but it's not around here.

Now that the bird is pointing the way, Lin Shuo picked up the clue again.

Bypassing the mountain and walking more than ten miles to the southeast, Zhang Jin raised his fist and made a stop gesture.

Although Zhang Jin can't be dumb, he still has a very standardized hunting gesture.

Then he looked a little anxious and began to gesture indiscriminately again.

Lin Shuo didn't understand his gesture much, but the expression on his face could still be understood, and he guessed seven or eight points.

Zhang Jin got the news from the birds, and from here, there began to be contradictions, some said this way, some said that there was that there.

This shows that this is the origin of the snowman's operation, and there are people who go in any direction.

The entrance to the snowman's hideout should be near here.

Lin Shuo twitched his nose twice, and found that he didn't smell anything.

Yesterday's heavy rain washed away all the previous smells.

Since the rain, the snowman probably hasn't been active around here.

This shows that the entrance to the snowman's hiding place is not just here.

As far as the eye can see, this is a valley, surrounded by coniferous forests, with poor visibility and muddy ground.

And at this time, A

E was already lying on the ground and listening quietly.

When Lin Shuo saw such a beautiful half of his face, he stuck to the mud with a "snap", and his eyelids twitched.

Before, whether it was dirt or gravel, A

E said that he lay down and lay down, and after he got up, there was either mud on his face or stone marks, and Lin Shuo didn't feel so big.

Hunters, go into the mountains to show their means, and always focus on practical results rather than appearance.

It's different now, Lin Shuo saw A

Half of E's face was on the ground, and he felt a little awkward and reluctant.

However, this kind of reluctance can only be expressed in my heart.

Just waited a little bit, A

E said softly: "The soil is too wet, and the vibration is so well absorbed that I can't hear it clearly. ”

"Master Su, do you want me to go for a lap?" Zhou Lingshi proposed at this time, "If I run, will there be a sound source?"

"It didn't work. ”A

E stood up, took out a wet tissue from his backpack, and wiped the side of his face, "You are an external sound source, and you can't get in." ”

Lin Shuo looked around and found that there was this kind of mud everywhere, so he simply pointed to the ground, "Plane, plane the mud clean and expose the stone layer." ”

After saying this, Lin Shuo pulled A

E's sleeves, and the two of them hid to the side.

As soon as Zhang Jin and Zhou Lingshi heard this, they hurriedly squatted down and ploughed the ground with their hands.

Although these two people have different thresholds, they are both on the path of cultivation, and they can withstand the mud, and the movement is unbearable, just like two excavators.

All of a sudden, muddy water splashed, and the two of them sank at a speed visible to the naked eye.

Five minutes later, the big pit dug by the two was half a person deep, and the two of them stopped their movements and looked up at Lin Shuo and A

e。

These two people were already thin, but now they look like two mud monkeys.

Looking at the pit dug by the two of them again, Zhang Jin went straight up and down, Zhou Lingshi thought about it more thoughtfully, and knew that this pit was bigger.

Because if the pit is too small, the future master of the Su family will have to gather her body in this pit and pout and listen, the posture is not elegant.

Therefore, Zhou Lingshi dug the soil, which is the kind of expansion type, not going deeper, but going to the side.

Since Zhou Lingshi had dug out the edge of the hole, Zhang Jin naturally understood it and helped him continue to dig.

Right now, this pit is just right for A

e The whole person lay at the bottom of the pit and listened slowly.

For this little thing, Lin Shuo could see that Zhou Lingshi was still more reliable than Zhang Jin.

The two jumped out of the pit, A

E jumps in again.

The biggest premise of the Su family's listening to the mountains and knowing the way is to have a sound source.

Especially when listening to the opposite side or inside through the stone layer, the requirements for the sound source are even more demanding.

It is not the volume of the sound source, but the fact that it must be an internal sound source, and it must be stable and clearly contrast with the rest of the noise.

For example, at the time of the underground of Dragon City, the water droplets dripping every minute above the waterhole, although there was not much movement, were the best internal sound source.

And yesterday's heavy rain, the movement was so big, and A

It takes a long time for E to realize that there is a dark hole underneath, which is the lack of internal sound sources.

......

A

e put his ears close to the stones at the bottom of the pit and closed his eyes.

At this time, the earth is like a string that is absolutely still, very silent.

But A

E was not in a hurry, she knew that her heart had not completely calmed down, and the voice inside her body, louder than the sound of the earth, had caused interference.

Breathing slowly slows down and enters a meditative-like state, allowing the internal disorder in your body to calm down and become a steady background sound.

The earth began to slowly become lively at this time.

But this buzz is not A

E wants at this time, because these are external sound sources, and the depiction of the contours of the underground space is useless.

At this time, you need to wait.

"Click".

A very small voice came into A

e eardrums.

In the same way that Lin Shuo can distinguish the type of smell, A

e also has a keen ability to recognize various sounds.

She quickly recognized what the voice was.

This is the movement of the sole of the foot without shoes touching the hard ground.

And it came from the ground through the stone layer.

The sound source, there is.

If nothing else, this should be the footsteps of a snowman.

But since it is a footstep, it is not a stable sound source, it must be moving, and it will stop at any time.

Hurry up!

But the problem is that the volume of the sound source itself is too small, and the diffraction of the spatial contour to this sound source is even smaller.

If you can't catch the diffraction of the sound source, the spatial contour can't be in A

e in the brain to form.

The entrance to this space is naturally not found.

So A

E reached into his satchel, took out a small porcelain bottle, and handed it over.

Seeing this, Lin Shuo hurriedly hurried to the edge of the pit in two or three steps, and reached out to catch the porcelain vase.

The two looked at each other, and without speaking, Lin Shuo knew A

What are you going to do?

He looked solemn and nodded slowly.

Seeing Lin Shuo's expression, A

E seemed to have no worries, and smiled relaxedly.

At the moment, the sound source underground is of poor quality, A

e requires the use of stunts.

That is the real method of the Su family "listening to the mountains and knowing the way":

Turtle Breath.

Because even if you enter a meditative state, A

The sound emitted by the various organs inside the body is still too loud to drown out the diffraction of footsteps.

Especially the sound of breathing and heartbeat.

And the turtle breath technique can make A

E enters a hibernation-like state, with breathing temporarily halted and the heartbeat slowing to less than twenty beats per minute.

This kung fu is difficult to practice, and this is also the standard for a Su family hunter's "listening to the mountain" stunt and whether he is proficient.

At the same time, this kung fu is also dangerous.

It has a lifting effect on "Listening Mountain", which is equivalent to a shot of stimulant. In a short period of time, it will indeed have a great improvement on "Listening Mountain".

However, over time, with the decline of various body functions, the nervous system will slowly enter a dormant state, and people will become sluggish and lose hearing.

And that's not even the worst outcome.

Once the turtle breath technique is used, the process is irreversible, and the person will not wake up on his own, but will slowly change from hibernation to suspended animation, and after that, the real death will come.

So it's a team skill, and someone has to be there to take care of it and wake up the caster at a critical moment.

In that porcelain bottle, there was a medicine that could wake up the Su family.

Before the Su family's heart stopped beating, wipe it on the temples and wake up immediately.

But who this porcelain vase is entrusted to for safekeeping, the Su family must be clear-minded.

Because whoever the porcelain vase is handed over, it is equivalent to handing over one's life to whom.

It has to be the person you trust the most.

At the moment, Lin Shuo is taking care of himself, A

E was not worried at all, and once again pressed his ears to the earth.

Brain, empty.

Breathe, turn off.

Heartbeat, slow down.

The silence inside the body, except for the faint heartbeat every three seconds, reached the extreme.

All eyes are on the eardrums.

"Click......

"Click......

"Click......

A

E waited for three footsteps, then lost consciousness.

......

I don't know how long it took, A

e Wake up.

She found that she was still in the pit, and Lin Shuo had already jumped down, squatted on the ground, and held her in his arms.

Hearing has been restored, A

e knows that the various organs of his body are waking up quickly.

At the same time, looking at Lin Shuo's expression, she couldn't help but feel a faint joy in her heart.

Because she saw it, Lin Shuo's brows were tightly furrowed and his mouth pursed.

He was feeling sorry for himself.

"It's fine. ”A

E smiled, took the porcelain vase from Lin Shuo's hand and put it in his satchel, and stood up with his support.

"Give me some time. ”A

E spoke, then closed his eyes again.

In A

When the turtle breath technique is performed, because the blood supply and oxygen supply to the brain are insufficient, it does not have the ability to analyze, only the sense of hearing and memory.

At this moment, she needed to remember the three footsteps she heard before she fell unconscious, and the diffraction caused by these three footsteps.

A

E has fought the snowman head-on, and knows that it is about two meters tall.

The span of its footsteps when it walks is about 80 centimeters.

This distance, which is also the moving sound source of footsteps, is objectively different from the distance that rings every time it sounded in this enclosed space.

At this time, rational thinking and perceptual perception are simultaneously in A

e plays a role in the brain.

It was difficult, but twenty years of hard training in a foreign land still bore fruit.

A vague three-dimensional spatial picture gradually formed in her brain.

The entrance, which is closest to the ground, should also be relatively narrow......

Got it.
