Lin Yue looked at the wall in front of him with a solemn expression.

This stone wall is like a great picture scroll, showing a strange and ancient ritual.

The far left side of the wall seemed to be the beginning of the whole picture scroll, and although the carved picture there was simple, judging from the huge wings, the head like a bird, and the big mouth like a long knife, Lin Yue couldn't help but think of the kind of creature he was very familiar with.

"Monster Pterodactyl ......"

He immediately thought of the opponent he was familiar with in the secret realm.

I also think of the lifelike sculptures between the altars not too far from here.

And that creature, Lin Yue was extremely sure that it was a monster pterosaur.

The monster pterosaur had two balls high on its head, and there were some small crosses or dots near them. Lin Yue immediately understood that this was referring to the two moons and the nearby stars.

Continuing to the right, the monster pterosaur spread its wings and flew into the moon to the left, before flying back to the ground again.

An egg appeared beneath the monster pterodactyl, and the next moment, the egg cracked open again, giving birth to a lizardman from within!

Lin Yue saw that the top of the lizardman's head was dotted with a huge bead, and the shape was exactly the same as the moon on the right side of the sky, but a small piece was missing on the right side.

The lizardman was kneeling at the monster pterodactyl, as if begging for something.

Continuing to look down, the number of lizardmen became much larger, and they began to make weapons and hunt, and finally took the prey to the monster pterosaur, and finally danced around it.

At the end of the frame, hordes of monster pterosaurs descend from the sky, and the lizardmen offer more prey.

However, it seems that this picture does not end the story.

Lin Yue looked around again, but there were no such carvings on the other walls.

But.

The problem with this carved painting is big, big.

It can be said that it even made him feel that it was really beyond his cognition.

There's so much information in it, and it's full of weirdness.

Whether it was why the monster pterosaur would fly to the moon on the left and lay eggs and become a lizardman, or the relationship between the beads on the top of the first lizardman's head and the moon on the right, Lin Yue felt puzzling.

And what Lin Yue couldn't figure out the most was the prey of the lizardman in the picture.

The prey was caught by the lizardmen from the ground, and each one was in the shape of a "human".

But what is completely different from the earthlings is that the "people" here have a pair of huge ears on the top of their heads!

Huge ears on the top of the head.

This thing should definitely not be something that earthlings have.

It's more like a beast, like a wolf or a fox or a cat or the kind of ears that only beasts have.

But in the picture, it is really displayed.

He saw this and took a deep breath.

Underground ...... Orcs caught from the ground? So, this underground ruin, is it an orc? And did the lizardmen originally live on the ground? Aren't those jars the earthlings who came later, but the orcs? Who carved this carving? Lizardmen, or orcs?

All kinds of questions kept rising and falling in Lin Yue's mind, but he didn't have any clues at all.

He shook his head, called up the system and turned on the camera function.

This new feature has been updated to produce extremely sharp photos that seem to be automatically fixed according to the survivor's line of sight, and even the smallest details can be displayed with extremely high pixels.

After Lin Yue took a picture of the whole wall, he stepped forward again and gently stroked the lines on it.

These lines have clearly been carved for quite some time, and are definitely not something that has been carved recently.

Looking around, except for this wall, there are no carved pictures on the other three sides.

"Is that all? Or ......"

The picture on the wall is obviously not finished, maybe there will be such a thing somewhere else?

Lin Yue felt that this was a survival game, but it also brought some elements of puzzle-solving.

"Quack!" Xiao Bai suddenly let out a low roar, Lin Yue thought that there was an enemy attack, but he saw Xiao Bai and Xiao Meng standing in the center of the entire room at the moment.

He suddenly noticed that there was a round, smooth pattern on the ground at Xiaobai's feet.

After walking over, Lin Yue saw that there was also a circle of the same size five meters away, but it was half pressed by a stone, and it was really not easy to find if you didn't look carefully.

What is it?

Lin Yue looked at Xiao Bai, his feet chopped off the ground, and he immediately heard the sound of "empty".

Is there something down here?

He looked at the circular platform again, then took out his pickaxe and, after chiseling the stone, cleared the barrier on this side.

"Xiaobai, you and I are standing on top of this round thing at the same time, at the same time!"

"Quack!" Xiaobai looked at his feet and knew what his master was going to do.

Lin Yue had seen a similar mechanism in a movie before, and the road would only open when the two of them stood on the same mechanism at the same time.

"One, two, up!"

He and Xiaobai stood on the circular pattern almost at the same time, and at this moment, suddenly there was a "gurgling" sound of stones colliding under their feet!

The dust rose from the cracks on the ground like sharp weapons, and Lin Yue soon saw that a black downward hole also appeared between the two circular patterns!

Hey guys, is this really going to be a puzzle game?

Lin Yue complained in his heart, but as he heard the last loud noise, the ground also returned to calm.

Can you go down?

"Xiaobai, is there any danger inside?"

"Quack." Xiao Bai shook his head, and Xiao Meng also shook his head.

Lin Yue, just in case, put a stone in the position where he and Xiaobai had just stood.

Taking out the flashlight, he walked to the front, and Xiao Meng jumped directly on his shoulder.

The circular astigmatism of the flashlight illuminated the steps that kept going down, and after walking for a while, Lin Yue finally reached the flat ground.

He looked up at the top and saw that even a flashlight couldn't reach the top, and it was so empty that it seemed to be in a huge space.

"Quack." Xiao Bai let out a low roar, and trotted in one direction, and Lin Yue ran after him.

The light of the flashlight kept shaking, and Lin Yue gradually saw what was in front of Xiaobai clearly.

"What? It's ......"

It's a cluster of skeletons!

Lin Yue stopped, he didn't expect that what he finally saw was this.

But......

Human bones? No, the earth has only been here for less than three weeks, how can there be such a large number of human bones.

Lin Yue picked up one and looked at it carefully, and found that it seemed to have existed for a long time, and the color was a withered yellow color.

Could it be that they are...... Those who have animal ears in the carved patterns?

Lin Yue let go of his bones and fell into deep thought.

However, it was also at this time.

In the empty space, the system suddenly made a sound!

[Congratulations! You've unlocked all of the map areas in Underground Ruins Area F! 】

[Rewards will be distributed, please check in time!] 】

A white light suddenly flashed in this empty underground area, and Lin Yue suddenly noticed that there was something more beside him.

"Treasure chests? Wait, this material...... It's not wood, iron, copper, silver, gold, what is it? ”

The glowing treasure chest in front of you is much bigger than ever!
