"How...... Why is it gone?"

The Youyun Mountain Range, like the Lost Ancient Town, is a little dim, and there is also a gloomy wind.

At the west exit of the Lost Ancient Town, a hole the size of a well appeared on the maroon ground, and Jiang Tian lay down at the entrance of the cave, staring deadly down.

Ye Ran fell into this cave, he couldn't even see a shadow, no matter how much Jiang Tian shouted, he couldn't hear a single echo.

Jiang Tian turned over and wanted to jump into the hole, but was stopped by the dragon girl.

"I'll go first, and the three of you will wait on here. The dragon girl looked at Jiang Tian with a serious face and said.

"But you ......" Jiang Tian was stunned, how could he let the dragon girl go down alone? The ghost knows what kind of thing is hidden under this cave entrance!

"Don't worry, I will never let Ye Ran have anything to do. The dragon girl looked at Tang Xuan and said, "Tang Xuan, you just guard this ground and don't let any danger approach." ”

Tang Xuan hesitated for a moment but nodded, although he also wanted to go down to help Ye Ran, but there must always be a powerful guard on the ground.

"If we don't come up, let us go. ”

When the dragon girl fell into the hole, she said her last words.

"You ......" Jiang Tian was about to say something, but found that the figure of the dragon girl had been engulfed in darkness.

"Let's stay here well, and when the time comes, we can respond to Ye Ran and them. Xun Rongyue looked at Jiang Tian with a sad face and said.

"That's all I can do. Jiang Tian gave up, so he had to nod helplessly, he only prayed that there was no danger below, and Ye Ran and the dragon girl could return safely.

......

......

The moment the dragon girl entered the cave, she felt a hot air from the pavement, which was stronger than that on the ground, wave after wave.

It was all dark and she couldn't see anything, and the dragon girl could only hear the wind whistling in her ears, and the hole was straight, so the dragon girl's body just fell downwards without the slightest obstacle.

The dragon girl felt like she had been falling for a long time, and she looked down but still didn't see the light or anything else, obviously not reaching the end yet.

The heat rising from the ground was getting higher and higher, as if there was molten or some other hot thing underneath.

"Underground molten lava?" the dragon maiden couldn't help but start to think back to the information about this area, what exactly was there in the northern part of the Cloud Mountains?

Thinking about it again, the dragon girl couldn't help frowning, she remembered that she had caught a glimpse of something amazing when she was looking at the secret scroll, but now she couldn't think about it.

Suddenly, a glimmer of light stung the dragon girl's eyes, and she looked down to see that it had landed.

Be ready to land, the moment the dragon girl lands, she will fall safely.

When she stood up, she found that this was a vast underground world, the ground was neatly paved with gray square floor tiles, neat, dense, and there was nothing around, and the dragon girl stood here, like a chess piece in a chessboard.

There are torches shining on the surrounding walls.

"Why did you come down?" Ye Ran looked at the dragon girl who fell.

"Are you alright?" the dragon girl looked at Ye Ran, who was intact, obviously the latter did not encounter any danger.

"I'm fine. Ye Ran shook his head, from the time he fell to the present, there was no danger.

"What the hell is this place?" The dragon girl looked at the endless floor tiles, looking at the lines of the floor tiles, it was inevitable that it looked a little grandiose.

"I don't know. Ye Ran shrugged his shoulders, and then he pointed straight ahead and said, "What do you think that mural is?"

"Where?" the dragon girl immediately raised her head and looked in the direction that Ye Ran's finger was pointing, and then she saw an extremely shocking scene, on the wall in front of her, there was a huge mural, and each notch of the mural was the size of an adult's body, in front of this mural, they were just an inconspicuous grain of sand.

Such a magnificent spectacle is enough to shock people's hearts.

The mural depicts a small farmer in a patched garment, squinting with wrinkles on his face, wearing a felt hat and a beard, his hands stretched out, as if holding something in his palms.

The whole mural is colorless, except for the farmer's heart, which has a bright red, as if someone has casually skimmed it, and it has been glued to a touch of red.

"What is this?" Rao is a well-informed dragon girl couldn't help but be stunned, who is this farmer? Why is his heart red? What is he holding in his hand?

"I don't know. Ye Ran shook his head quietly, this underground world is empty, but there is only such a mural, if you want to understand the mystery, you can only start from this mural.

Ye Ran walked towards the mural, and suddenly the floor tiles under his feet were slightly dented, Ye Ran was startled and immediately jumped up, took a few steps back, and had the experience of the previous car that inexplicably fell from the ground, Ye Ran could be said to be careful step by step.

"Boom!"

A loud bang rang out in the underworld, a rumbling sound that shook the ground.

In the distance, the ground suddenly cracked, and a regular circular cavern emerged, followed by the skeleton of a demon beast.

"Could it be that it's an evil spirit creature again?" Ye Ran couldn't help frowning, he had obviously left the Lost Ancient Town, could it be that this underground world was inextricably linked to the Lost Ancient Town?

The monster-like skeleton was like a tiger, with razor-sharp claws, but its back skeleton derived from three pairs of skinny bone wings.

The dragon girl couldn't help but shrink her pupils when she saw the monster-like skeleton, "This is...... It's ......"

"What is this?" Ye Ran stared vigilantly at the skeleton with wings, and couldn't help asking, obviously the dragon girl knew this guy.

"Isn't this the extinct demon beast in ancient times, the Heavenly Devouring Six-winged Tiger?"

Ye Ran didn't hear the Six-winged Tiger that day, he only heard that this was a demon beast that had already been extinct in ancient times!

The demon beasts in ancient times are very different from now, the demon beasts at that time were extremely fierce, and they all had the means and ability to turn over the river and the sea!

How come there are still skeletons of ancient monsters here?

"It doesn't make sense......" The dragon girl stared at the Seraphim and shook her head, it stands to reason that even if it only had a skeleton left, it shouldn't be in this kind of place.

Although there was only a skeleton left of the six-winged tiger that day, it was still able to move, it slowly moved two steps forward, and the six wings behind it fanned, and let out a roar at Ye Ran's dragon girl.

"Roar!"
