So later, Guard Yan also discovered clues.

"What's the sound?!"

His spirit suddenly shook, as if he was shocked by electric shock, and he turned around in shock and looked around.

"I seem to hear something...Miss Ling..."

Ling Luoyu rolled his eyes: "Didn't you tell you a long time ago?"

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

He seemed to have thought of something, and when he looked at Ling Luoyu's eyes, there was a little more admiration and incredibility.

"Miss Ling, you have heard it long ago?"

Hearing from Ling Luoyu and taking him to hear, there was a long way to go!!

You can hear this distance, what is the girl’s ear made of?

Ling Luoyu was too lazy to pay attention to his admiration and pointed forward.

"We shouldn't be far from Jikuo!"

"Machine??" Guard Yan became more and more energetic: "You mean, we have an organ in front of us? Once we find the organ, can we go out?"

"have no idea……"

Ling Luoyu is not as optimistic as Yan Shiwei.

The existence of the mechanism just means that their direction is correct and they have found the core of the dungeon.

But only God knows what will happen after you reach the core!!

The two followed the sound and went deeper.

As they move, the extremely loud sound of gears turning becomes louder and louder, and their locations become drier.

Finally, after turning into a hole, everything in front of them made their pupils suddenly shrink.

In front of them, there was a huge cave.

In the cave, there are countless biting gears.

They rotate little by little, without stagnation due to the passage of time.

“Where is this place?!”

Guard Yan held up the torch and looked up incredibly.

It is pitch black on the top and there is no end to see, but when it comes to the sound, it is also the rotation of the gears above.

Ling Luoyu walked into the gear with a serious look on his face: "What I care more about is who made these things..."

Each gear has a diameter of half a meter, with clear edges, smooth edges, and very exquisite workmanship. The gears that never get into each other are flawless, leaving no gap.

What kind of person must be able to make such accurate things?!

"Miss Ling..."

Guard Yan suddenly held up the torch and screamed, as if he had seen a ghost.

"What?!"

“Here…there are roads here…”

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

The stone path was chiseled on the basis of the wall, and was only thirty centimeters wide, which was only enough for one person to walk sideways.

Guard Yan tried his best to shine on the torch, and raised his head and murmured: "You said, where does this road lead to?"

"You'll know if you go up and take a look?"

Ling Luoyu lifted up the corner of his skirt and lifted his feet up.

But after one step, she stopped and suddenly pulled back.

Guard Yan was about to follow her, but was startled by her movements. He quickly took two steps back and looked at his feet in horror.

"What's wrong?"

"These are stones..."

Ling Luoyu's fingertips brushed across the wall on one side, and looked at Guard Yan with a slightly strange look.

"Look at this place, is it the same as the cave you feed the holy beasts...the stones?!"

Guard Yan looked at her suspiciously, but he still stepped forward to check it out himself and nodded repeatedly.

"Yes, yes, we call this fire stone. Because this thing seems to be burned by fire, it turns brown in color, and it is layer by layer, with clear layers, so it is called fire stone..."
