Everyone consciously dispersed and walked around, looking for possible organ hubs.

If there is a secret door, there must be an opening mechanism.

It's just that the hidden door is so concealed that it's even harder to find the opening mechanism.

Seeing everyone groping on the wall for possible mechanisms, Ling Luoyu retreated silently.

Gu Lan noticed her strangeness and couldn't help but glanced at Concubine Liang, Zhan Cheng and others, and retreated to Ling Luoyu's side.

"Have an idea?"

"I can't tell...just feel!"

Ling Luoyu frowned slightly, looking at the figure of Zhancheng and others.

"If you are an ordinary person, if you are looking for an agency... what will be the first reaction?"

"Of course it's the wall!"

Gu Lan's lips pointed to the people inside.

"Just like a few of them..."

"Yes! This is the normal thinking of ordinary people..."

"So, the agency we are looking for... will not take such an ordinary route!"

Gu Lan instantly understood Ling Luoyu's meaning, and suddenly looked around.

"The mechanism that opens the door may not be on the stone wall at all, but on something in the cave..."

"It may be outside..."

Ling Luoyu and Gu Lan ignored a glance and walked out of the cave.

On the other hand, Gu Lan carefully inspected the stone tables and bed and other objects to see if he could find out the unusual.

Standing outside the entrance of the cave, Ling Luoyu turned his head to look around, frowning even more.

"This direction...to...north..."

When a man builds a house, his favorite orientation is the south.

Because the sun is full!

No matter how bad it is, you have to go east or west.

In this way, more or less, there is always a little sunshine.

But the direction she is facing now is indeed north!

Throughout the year, twelve hours a day, there will never be sunlight coming in!

why? ?

Was it due to limitations when the cave was built? ?

But how can someone who can build such a perfect cave be limited by direction!

unless--

"Unless this cave... there is a problem in itself!!"

Ling Luoyu murmured, stepping back, looking at the cave with his head up.

There are two people in the cave, twenty steps deep, big or small, not small.

On the top of the cave, there is a willow tree with a crooked neck.

Xu is because of the lack of water, the willow tree has dried up, leaving only the branches with teeth and claws, standing silently above the cave.

"Gu Lan!"

Ling Luoyu whispered and leaped over to the willow tree.

Almost at the same time, Gu Lan and Concubine Liang came together.

Later, Zhancheng and others followed suit.

However, Ling Luoyu was speechless after all the people came, just circled the willow tree with crooked neck.

Concubine Liang followed her gaze, her eyes slightly stunned: "Miss Ling, did you find something?!"

"Lady Concubine, have you ever checked this tree before!" Ling Luoyu suddenly stopped his steps and stroked the tree with his right hand.

"A tree that has withered, what can be seen!?"

Concubine Liang obliquely glanced at the willow tree.

"You don't mean to say that this tree is an opening mechanism?!"

The organization must be set in a place that will not be corrupted for thousands of years and can be used for thousands of years.

This dead tree has reached the brink of destruction.

It is estimated that as long as anyone sneezes, it can be destroyed, how could it become the setting of the agency! ?

"But I think it looks like this, it can be broken with one touch... how can it be set as a trap!"
