I gently stroked the edge of the hole...uuk.la

The rocks are cold and hard, and you can feel the obvious digging marks on the side of the hole, just like a watermelon peel shaved with a spoon.

What sharp claws do you need to dig through thick granite?

I turned around and came to the iron fence and looked at the claw marks on it.

Everyone could see that the monster's cage in the cage was as sharp as a steel knife, and under one claw, it was enough to cause a broken bone.

But it is still far from grabbing any iron bar here.

Since the iron bar is constantly grabbing, why should it take a hole in the same hard stone?

With many questions, I got into the hole.

At this time, the wonderful use of the loach skill is fully reflected.

Just like the last time I drilled the ventilation duct, my progress was basically squirming, but under the lubrication function of the loach, I just twisted my shoulders, waist, and legs a little, and my whole body was like soap falling into the sewer, huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh huh hu

With a sharp turn, I turned into another passage.

Of course, while gliding, I was also paying close attention to the movements around me to prevent myself from silly hitting into the monster's mouth.

Suddenly, a strange breathing sounded in front of him.

There are really monsters!

I held my breath and stopped urgently.

Woo... Woo...

The slight breathing sounds intermittently, appearing mysterious and weird in the darkness.

The refined fire folds I tied to my forehead can only illuminate the range of about two or three feet in front.

what to do?

I decided to do a test first.

He took out a flying knife and pushed it out hard against the ground.

Wow...

The flying knife rubbed against the inner wall of the pipe and slowly slid into the depths of the darkness.

I have calculated the strength. Within five breaths, the flying knife should be able to slide out a distance of one meter. If you touch something in the middle, the friction will stop.

Five breaths passed, and the friction sound stopped.

This flying knife successfully completed its own extreme distance.

Is there nothing in front?

I took out another flying knife.

Increase the strength and launch.

Wow...

Within ten breaths, the flying knife will reach two feet away.

One breath, two breaths, three breaths...

But when I counted until seven, the pipe suddenly became quiet.

The sound of the flying knife friction stopped!

I stared at the darkness ahead, guarding against monsters that would rush out at some time, and my energy was ready to go, ready to escape at any time.

Ten breaths, eleven breaths, twelve breaths...

Time passed quietly, my knuckles turned white due to force, and my muscles became sore due to excessive tension.

The strange breathing still sounded from time to time, but no monster rushed over.

Didn't the flying knife alarm it?

Or is it waiting for me to move first and prepare to take action?

Wait... In a similar plot, monsters usually have gone behind the victim, just waiting for you to turn around and run away, and a bloody mouth will be chewed down immediately!

I feel my hands and feet are cold.

You can't let the rhythm fall into the other party's control!

Whoosh...whoosh...

I shot a flying knife to both sides of the passage.

bite.

The one shot in front fell on the hard object.

Bang.

The one shot at the rear fell gently after its strength was exhausted.

It seems... there is no movement on both sides?

After waiting for a while, I finally mustered up the courage to continue touching forward.

One foot, two feet, three feet...

One zhang, two zhang, three zhang...

There was no third zhang. After moving forward for more than one zhang, I saw a thick road blocking stone.

dead end!

Yes, there are no monsters here, and three flying knives are lying on the ground.

What happened to the mysterious breathing sound?

I climbed to the end of the passage and felt a strong air flow passing by the sideburns.

After a closer look, there were several narrow and long openings on the side stone wall. When the strong air flowed through these openings, it would make a sound similar to breathing.

It turned out to be a false alarm...

Don't be careless!

I still maintain a high degree of alertness and continue to explore other directions.

At the same time, I also figured out one thing - ventilation ducts are naturally connected to a secret room. How can I avoid being found by someone through the duct?

These narrow and long suction vents are the answer.

In order to collect enough air volume, the ventilation duct must be wide enough, but at the end, some means can be used to press air into narrow ducts that humans cannot pass through, thereby avoiding exposure of the secret room location.

If the designer is smart enough, he can even design a few more fake air sucking outlets to confuse those of us who are coveting the treasures of the secret room...

Isn’t it smart enough to design someone from the Demon Palace?

I suddenly realized that this time, I was probably in vain.

withdraw!

I sighed and wondered how I could leave this small and dark ghost place as soon as possible.

Turn left?

Swipe right?

By the way, this place should lead to the nearest inlet...

I slowly moved forward in the passage, and at the same time I was depicting a diagram of ventilation ducts in my mind.

You can't make a mistake. If you turn ahead, you should go to the Wild Boar Palace...

wrong?

I accidentally found that there was no way ahead.

Did you remember it wrong?

Just as I was about to turn around and find my way again, a sudden strange feeling filled my heart.

I immediately understood:

The reason for this strong sense of incongruity is that...

Suction vent!

There is no air sucking outlet in this dead end!

Some people may say: Do you have to have a suction vent in a dead end?

Of course not.

But there were all dead ends just now, and now this one suddenly disappeared. Isn’t it worth paying more attention?

So I noticed.

With this attention, cold sweat suddenly flowed.
