Chapter 2413: Igneous rock

So later, Yan Shiwei also discovered the clues.

"This is... what sound?!"

His spirit shook suddenly, as if he had been shocked, he turned around in shock and looked around.

"I seem to have heard something...Miss Ling..."

Ling Luoyu rolled his eyes: "Didn't you tell you already?!"

Officer Yan suddenly realized: "Oh... this is the voice you are talking about?!"

He seemed to have thought of something, looking at Ling Luoyu's eyes, there was a little more admiration and incredibleness.

"Miss Ling, have you heard it before?!"

Hearing from Ling Luoyu, leading him to hear, there was a long way in between! !

You can hear it at such a distance. What made this girl's ears?

Ling Luoyu didn't bother to pay attention to his worship and pointed forward.

"We should not be far from the camera!"

"Mechanical??" Yan Shiwei became more energetic: "You mean, there is a mechanism in front of us? If we find the mechanism, can we go out?!"

"do not know……"

Ling Luoyu was not as optimistic as the Yan guard.

The existence of organs just means that they are in the right direction and have found the core of the dungeon.

But what will happen after reaching the core, then only God knows! !

The two followed the voice, deepening all the way.

As they progressed, the sound of extremely gears rotating became louder and louder, and their locations became increasingly dry.

In the end, after turning into a hole, everything in front of them caused their pupils to shrink suddenly.

In front of them, it turned out to be a huge cave.

In the cave, there are countless biting gears.

They are rotating a little bit of machinery, without the slightest stagnation due to the passage of time.

"What is this place?!"

Guard Yan held up the torch and looked upwards incredibly.

The top is dark and there is no end in sight, but listening to the sound, it is also the sound of gears rotating above.

Ling Luoyu walked into the gear, his eyes solemn: "I am more concerned about who made these things..."

Each gear has a diameter of half a meter, with clear edges and smooth edges. The workmanship is very exquisite. Every time the gear bites, it fits flawlessly, leaving no gap.

What kind of person is necessary to make such a precise thing? !

"Miss Ling..."

Guard Yan suddenly raised the torch and screamed as if he had seen a ghost.

"what?!"

"Here...there is a road..."

Looking at the sound, I saw an upward stone path on one side of the wall.

The stone path was cut out on the foundation of the wall, and it was only 30 centimeters wide, which was enough for a person to walk sideways.

Guard Yan shot up with a torch as much as possible, and muttered, "You said, where does this road lead?!"

"Go up and take a look, don't you know?!"

Ling Luoyu lifted the corner of her skirt and raised her foot.

Only after one step, her footsteps stopped eagerly, and she suddenly pulled back.

Guard Yan was about to follow, but was startled by her action, and quickly stepped back two steps, staring at her feet in horror.

"what happened?"

"These are stones..."

Ling Luoyu's fingertips brushed one side of the wall, and his eyes looked at Guard Yan with a slightly strange expression.

"Look at this, is it the same as the cave where you feed the sacred beast... the stone?!"

Guard Yan glanced at her suspiciously, but went forward to check for himself, and nodded repeatedly.

"Yes, yes, we call this Flintstone, because it looks like it has been burned by fire, the color is brown, and there are layers of layers, so it is called Flintstone..."
