"..." The white-headed man was speechless for a moment.

yes!

How did he ignore the most important key?

When people survive, they can have nothing to eat, but they must have water to drink!

Especially when choosing a place to live, you must get close to the water source.

But--

"I just looked around and there was no water source!"

Jia Guizi and Ding Buliu also noticed this: "Yes, although there are some trees, grass and barley here, they are sparse and not in a climate!"

In short, this place is not suitable for living!

Zhan Cheng looked up at the cave, and Ling Luoyu and Gu Lan's figures appeared faintly.

"Perhaps, they can find the most appropriate explanation!"

Ling Luoyu stood in the corner of the wall, looking at the oval corner, standing still.

Gu Lan frowned slightly and walked forward: "Did you see something unusual?"

"Don't you think everything in this cave is too round?"

From the perspective of the naked eye, everything here is a complete whole.

It looks extremely smooth.

"It seems that this place has been carefully polished and repaired... But is such a simple cave so carefully polished?"

"Yes!" Gu Lan's palm swept across the stone wall: "Elaborate modification... is a kind of concealment in itself!"

Suddenly—

He paused and suddenly touched backwards, looking at Ling Luoyu with burning eyes.

Ling Luoyu saw his strange color: "What did you find?"

"a little!"

Gu Lan's palm wandered on the stone wall, and finally stopped at a corner, with the corner of his lips rising.

"Finished!"

His finger bones hit the stone wall hard.

“There are seams here!”

Ling Luoyu understood and looked horizontally from one side to avoid the direct light.

Sure enough, when looking at this angle, there was a shadow of light cast on the stone wall.

"There are shadows...it means that these walls are not as smooth as we see. They just borrow the principle of light refraction to make them look smooth like a mirror!!"

The two looked at each other and tacitly groped on the stone wall.

Finally, at the corners of the two sides of the stone wall, gaps were found separately and they were marked out with a pen.

"What are they doing!?"

Ding Buliu had sharp eyes and saw the unusualness of Ling Luoyu and Gu Lan.

"What did they draw on the wall?!"

“…It seems like a door!”

Before Zhan Cheng finished speaking, he suddenly understood something.

"They found the agency!"

When Concubine Liang heard the movement, she suddenly turned her head, and saw Zhan Cheng and others flying into the cave, and also rushed over.

"What have you found?"

"I don't know..." Gu Lan dipped his brush in ink and continued to draw on the stone wall.

Judging from the outlines that have been drawn, it is the shape of a door.

Zhan Cheng and others' eyes wandered along the brush, their eyes were horrified.

"There are really institutions..."

"It can be found in this way!"

"admire!"

“…”

Concubine Liang squeezed away everyone, walked to the stone wall, raised her hand and stroked her: "It really is..."

Why didn't she notice these unusual things at the beginning?

If I had discovered it earlier, maybe I would have been outside and started a new life!

"We just found the outline of the gap, which looked like a door, but the mechanism has not been found yet!"

Ling Luoyu bit the pen holder of the brush and his eyes wandered on the stone wall.

"You all look for it. Where will the mechanism that opens this door be hidden!"
Chapter completed!
