Judging from the walking, 300 meters of the flat road seems to be not far away, but you can look in a straight line from the height to the bottom, and 300 meters is really high.

In particular, the black hole is pitch black, giving people a dark sense of horror, which makes people turn from horror to fear and fear, which is the instinctive fear of human beings for the unknown environment or unknown species.

If you can't overcome it, you will always see it, think of it, and be afraid.

Just like at this time, this is a very specific height number, which made the three grandfathers look stiff, shook their shoulders, and shrunk their necks, and then smacked their tongues and said:

"Good boy~, it's very deep, it makes people hair straight when you listen to it, if this goes down, the ghost knows how to be scared!"

"Out of breath!"

The fat grandfather rolled his eyes at Grandpa Jin and snorted coldly.

"When I first went into the cemetery to dig up the graves of the dead, why didn't I see you afraid? When you meet zongzi, aren't you quite calm and chop it with a mahogany axe? Why is it cowardly now? ”

"It's not! Can this be the same? ”

Grandpa Kim glared.

"Go to the tomb, you know what will happen, and you have a bottom in your heart! Left and right are just those things—"

"But here, everywhere is weird, it seems to be pleasant, the wind and waves are calm, but it is so peaceful that it makes people creepy! The devil knows for a while, will there be something that shouldn't exist? ”

"Especially this kind of black hole, just like the big mouth of the demon and monster, waiting to swallow people, I am instinctively afraid, human nature! Where's the cowardice? You're not cowardly? Then don't shrink your neck, shake your shoulders, and tremble your legs! It's as if the whole person is blind and can't see it! ”

……

Okay, is what you said reasonable?

The fat grandfather tugged at his mouth and hummed.

"Is that still down? I can't get out and can't get out, there's nothing else around here, maybe the way out is down, we can't just stare at it, do nothing, if that's the case, but we won't be able to last a few days and we'll starve to death of thirst! ”

"Of course!"

Grandpa Jin glanced at him.

"I'm just cowardly! I didn't say I couldn't go on, I didn't find a way! ”

…… is so reasonable, it seems that this old thing is not only older, but this cheek is also growing exponentially!

The corners of Fat Grandpa and Grandpa Qian's mouths twitched, and they were both speechless for a while.

And, looking at the marks on the stones and rubber ropes, Gu Bai squinted.

It's weird—

It's not the right amount of humidity.

Since the water in the hot spring lake comes out at one end and flows downward, it means that there is not only a circulating heating system below, but also a strong pressure switch valve, whether these are natural or artificial, it is inevitable after all, otherwise the hot spring water cannot circulate and flow, let alone heat.

In particular, the hot spring lake is still high and bottom, the bottom is the spring, and the high place is the circulation mouth, this abnormal reverse current design, the pressure impulse needs to be doubled speed impact, and the hot spring lake will dry up.

This means that the circulating heating system, and the pressure switch valve can be closed.

So, this hundred-pound boulder and rubber rope, from head to tail, do not have any anti-impact and vibration dyeing phenomenon?

Moreover, the humidity on the boulder and the rubber rope are very different, the skin is stained with water vapor, but the inside is still dry, the rubber rope is so abnormal, and the hole she secretly poked in the stone is also dry, which is completely wrong.

And—

Since there was a circulating heating system and a powerful pressure valve, why hadn't the black hole been steaming since the moment she saw it?

The steam in the hot spring lake, except for floating in the lake, does not seem to escape outward?

"—Sure enough, water is water and stone is stone, but isn't it water and stone?"

This is undoubtedly a tongue twister, which makes the four of them have a question mark in their heads.

“？？？？ What the hell???? ”

What does it mean that water is water and stone is stone, but is it not water and stone?

No, can you speak human language?

They don't understand, hey!

The three confused grandfathers looked at the school flower and begged for an explanation.

Correct.

The school flower jumps with sideburns and gnashes her teeth.

"No, yes, yes!"

"Oh~"

The three grandfathers nodded in unison, satisfied.

"Okay, it's not that we don't understand, it's not that we have a low IQ, it turns out that everyone is the same, it's just that this kid is too winding, well, there's nothing wrong with it!"

…… I-

Did I just wash off the not-so-smart Ako before, and now I'm dyed again?!

Can it still be better?

Can you have a lot of fun!?

The school flower adults who are about to become a little toad want to squirt out a mouthful of poisonous juice and poison the three of them!

However, the smiling young man who looked at them blindly did not give much explanation at the moment, after all, everything was in her guessing stage, and she would give a concise explanation when she found the real hammer.

Right now, it's too troublesome to explain, and in addition to her, the four big and small ones in front of her are indeed very unsmart Yazi~

So, well, be a good person and do good deeds, and you won't hit people~

So, Su Gu Bai groaned and gave his opinion.

"-As of now, it's not dangerous, but-"

She paused, blinking as a few people looked over.

"Maybe there isn't enough oxygen, can the three grandfathers resist it?"

Uh-

The three of them were stunned, yes, this is a real problem.

If this goes down so deeply, will the three of them be angry enough?

But, let the two little guys go down, they really don't feel at ease-

For a while, a few people looked at me, I looked at you, and I had no idea.

Shu Qianluo glanced at the three of them and looked at the young man.

"Shall I go down first, or shall you go first?"

Yo?

Learn to ask for advice and not be arbitrary?

It seems that this 'various training' has been very useful recently~

Keep up the good work~ Keep up the good work~

The young man's smile is pure and good, but it is meaningful.

The three grandfathers shook their heads directly and refused without hesitation.

"This won't work! No matter how powerful you are, no matter how capable you are, don't be blind at this time-"

"That's right—"

Grandpa Qian echoed Grandpa Jin's words and nodded cautiously.

"If you want to go down, the three of us old guys will go down first, after making sure that there is no danger, you are down, although we may not be as good as you in terms of force value and other abilities at the moment, but in terms of experience, you may not be able to catch up with us in the last seven or eight years, so-old rules?"

Grandpa Qian, who said this, showed a malicious smile to Grandpa Jin and Fat Grandpa, which made the sideburns of the two of them burst out and sneered.

"Come on! The old rules! I don't believe you old boy can win for decades! ”

？？？？

Su Gu Bai and Shu Qianluo looked at the steady horse step curiously, looked up to the sky and inhaled, and then held back their strength-
