"More than four hundred years... Then you... are old enough!"

Laughing at himself, Feng Chenglin walked to the bronze wall and raised his hand to stroke the pattern on it.

"These patterns..."

"do not move!"

The voice of Dingmiao's change of tone suddenly came, and Feng Chenglin's hands froze in midair.

"what happened?"

"Each of these patterns is the evolution of the mechanism... you move anywhere, it will cause the mechanism to change!"

A cold sweat burst out of Feng Chenglin's back, and he subconsciously shrank his hands, backed away, and looked up with shocking eyes.

"You mean... the patterns here... are none of them?!"

"Yes!"

Dingmiao's voice was deep and hoarse, with obvious vibrato.

"That was when I was very young... The memory is still incomplete... At that time, my grandfather held me and visited the organ mound he made... Although I didn't understand anything, I remembered it. Huge and dazzling... Later, when I grew up, I never saw this again. After a long time, I have forgotten... Unexpectedly, I saw it here again..."

Ling Luoyu was thoughtful, and his mind was completely on another matter: "You... grandfather built this organ mound... and the girl in black asked for your name..."

Dingmiao and Fengchenglin turned their heads together and looked at each other with flashing eyes.

"San Shao...what are you going to say?"

"You mean... the girl said I'm still useful... is it related to this institution?"

"I don't know..." Ling Luoyu's eyes closed slightly, only that his mind was in a mess.

She is an outsider, everything she knows is a little clue.

How could she find the focus of the matter in the traces of harmony? !

"I can't tell... it's just an intuition..."

Her eyes slowly opened, staring at her surroundings.

"Your appearance, and the appearance of the Miao family's things, must have an inevitable connection..."

"Ahem..."

Feng Chenglin suddenly coughed and raised his finger to a place in front of him.

"That...two...Is this normal...or abnormal!?"

On the wall in front of him, several patterns were spinning, wandering, and changing patterns at a speed visible to the naked eye.

"This is someone starting the mechanism..."

Dingmiao stepped forward, pressed his ear to the wall, and listened to the sound of the pattern turning.

Feng Chenglin subconsciously wanted to listen, but Ling Luoyu grabbed his arm.

"Don't move!"

"I don't move... just curious..."

"Fat man, in such a place, you'd better not be curious!"

Ling Luoyu stepped back and stood in the center of the room.

"Curiosity will kill the cat..."

"why?"

Feng Chenglin's face was stern.

"Who is curious? Why did he kill the cat?"

"Your uncle..."

Feng Chenglin laughed out: "I am not nervous about seeing you and Dingmiao, so I am thinking about relaxing your mind..."

"Hush!"

Ling Luoyu suddenly pressed his lips and pulled Feng Chenglin back two steps, looking down at his feet.

At the same time, Dingmiao, who was listening to the sound by the wall, turned around suddenly, staring at the place where Ling Luoyu was standing just now.

There, a circular arc was slowly expanding, revealing a dark hole.

In the entrance of the cave is a spiral staircase.
