Chapter 4238

“……” The old man was speechless for a moment.

Yeah!

How did he ignore the most important point?

People in the survival of time, can not eat, but absolutely must have water to drink!

Especially when choosing a place to live in, it should be close to the water source.

But --

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

Jia Guizi and Ding Buliu also noticed the same thing: "yes, although there are some trees, grass and barley here, but it is sparse, not a climate!"

In short, this place is not suitable for living at all!

When he looks into the cave, the figures of Ling Luoyu and Gu LAN are looming.

"Maybe they can find the most appropriate explanation!"

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

Gu LAN micro frowned and stepped forward: "do you see anything unusual?"

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

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

It looks very smooth.

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

"Yes Gu Lan's palm crossed the stone wall: "meticulously decorated It's a cover up

All of a sudden -

he moved for a while, then suddenly he touched back, and his eyes were burning at Ling Luoyu.

Ling Luoyu saw his color: "what did you find?"

"A little bit!"

Gu Lan's palm walks on the upstream of the stone wall, and finally stops at a corner, and the corner of his lips rises.

"Found it!"

His phalanx struck hard on the stone wall.

"There are seams here!"

Ling Luoyu understood and avoided the direct light on his side and looked horizontally from one side.

Sure enough, when you look at it from this angle, there is a shadow cast by light on the stone wall.

"There is a shadow It shows that these walls are not as smooth as we see them, but they just borrow the principle of light refraction to make them look as smooth as a mirror! "

Two people look at each other, tacitly groping on the stone wall.

Finally, cracks were found at the corners of both sides of the stone wall, and they were marked with a pen.

"What are they doing?"

Dingbu willow eye tip, saw Ling Luoyu and Gu Lan's unusual.

"What do they draw on the wall?"

“…… It's like a door! "

Zhan Cheng's voice did not fall, but suddenly understood something.

"They found the mechanism!"

When the imperial concubine heard the news, she suddenly turned her head and saw several people flying into the cave, and they also swept her body.

"What have you found?"

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

From the outline that has been drawn, it is the shape of a door.

The eyes of Zhan Cheng and others swam along the brush with astonishment in their eyes.

"There is really a mechanism..."

"You can find it all in this way!"

"I admire you

“……”

The imperial concubine of Liang pushed aside the crowd, went to the stone wall, raised her hand and stroked: "there is really..."

Why didn't she find these unusual things in the first place?

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

"We just found the outline of the gap. It looks like a door, but the mechanism hasn't been found yet."

Ling Luoyu bit the brush holder, and her eyes were swimming on the stone wall.

"All of you, look for where the mechanism that opens this door will be hidden!"
