Not only was Zhao Xiyue surprised, but even Xiao Feng was taken aback.

I saw that there was a huge cavity inside, which was hollow and cylindrical in the mountain, as if it were ...... It hollowed out the whole mountain, and it was so dark that it would not have been visible if it had not been for the light that came through the door.

Xiao Feng took a small step forward, and in front of him was the cliff of the black hole, giving people a sense of depression.

"Boom"

When Xiao Feng was still immersed in the shock, the dragon gate closed suddenly, and Xiao Feng hurriedly rushed back, but it was too late.

There was no light from the outside, and at this time, the five fingers were not visible from the inside, and the darkness became viscous.

"Xiao Feng, where are you?"

In the dark, Zhao Xiyue's voice was weak, and there was a cliff in front of her, she didn't dare to move at all, so she had to stay where she was, shouting helplessly to Xiao Feng.

"It's okay, I'm here" Xiao Feng took out a strong flashlight from his backpack, and the white pillar of light instantly illuminated a space, and Zhao Xiyue dared to walk to Xiao Feng's side.

Holding a flashlight and fumbling around the stone door for a while, there was no mechanism that could be opened, Xiao Feng sighed: "It seems that this door can only be opened from the outside, we will definitely not be able to get out the same way, we have to find another exit." ”

He studied history in college, so he has dabbled in some ancient tombs and institutions, and knows that this kind of door is a very common mechanism that opens outside and closes inside, and if you want to get out, you can only go forward.

"Follow me, be careful. ”

Xiao Feng told Zhao Xiyue behind him, holding a strong flashlight and observing around.

The space at the top is so large that the mountain has been hollowed out, and it's hard to imagine what a huge project it is.

"Xiao Feng, there!" Zhao Xiyue saw something, and her tone changed slightly.

Xiao Feng used a flashlight to shine it over, only to see that there was a fist on the edge of the hollowed-out cylindrical mountain that surrounded the stairs on the mountain wall, spreading all the way to the darkness that the strong flashlight could not illuminate.

"There should be only one way, let's go" Xiao Feng said as he looked at the bottomless abyss.

Now that the mountain has been hollowed out and stone steps wind its way down, it's very likely that the people who built the ruins are the place they want to go.

Zhao Xiyue dragged the corner of Xiao Feng's clothes and slowly followed him to the stone steps of the mountain wall.

When Xiao Feng just stepped on the stone steps with one foot, a series of faint blue lights suddenly lit up, and they were embedded in the mountain wall next to the stone steps, as if they were to illuminate the entire stone steps down.

Xiao Feng took a closer look, and saw that it was glowing like a butterfly, but the body parts were bulging with some translucent bubble-like tissue the size of an egg, and it was this bubble-like tissue that was glowing.

"Huh, what is this, it's so beautiful!"

Zhao Xiyue saw that there was such a luminous thing in the stone wall, like fireflies, it seemed to move, and the bubble-like tissue that emitted a faint blue light seemed to be breathing, with a small regular expansion and contraction, and those faint lights also brightened and darkened with its movement.

After that, I want to touch this cute thing with my fingers.

"Don't move!"

Xiao Feng hurriedly stopped her.

Seeing that Zhao Xiyue was puzzled, Xiao Feng explained: "This should be a creature that can emit light like fireflies, do not rule out the possibility of poison, do not touch it easily." ”

"Oh oh" Zhao Xiyue nodded hurriedly, a little embarrassed.

Xiao Feng had to be careful, because he had never seen this kind of creature before, but generally bright and bright things were not so simple, and besides, this creature was very likely to be alive, but for some reason it fell into a state similar to hibernation, as long as someone walked up the stone steps, they would wake them up, which could also explain why they lit up as soon as they walked up the stone steps.

Since this stone step was leaning on the inside of the hollowed-out mountain wall, and on the other side was a huge black hollow, so Xiao Feng and the two walked against the mountain wall one after the other, although the faint blue light flickered on and off, but it also relieved some of the pressure of obstructed vision in the dark.

Soon, the two of them descended the stone steps to the bottom of the darkness, and the faint blue light at the top was no longer visible.

"It's so fragrant, have you smelled it?" Zhao Xiyue said.

"It's a little" Xiao Feng also smelled it, faint, like a floral fragrance, but he didn't know what it was, so Xiao Feng didn't say much, and continued to walk down.

When we are in darkness, we have almost no sense of time, on the one hand, because there is no reference object, and what we can see is the stone steps, the mountain wall, the blue light embedded in the mountain wall, and the endless darkness, and on the other hand, because the human brain is in a state of tension, and the fear of the unknown will make people lose their judgment of things.

In this environment, both of them didn't speak, and they didn't know how long they had been walking, Zhao Xiyue finally couldn't help it, pulled the corner of Xiao Feng's clothes, and said, "Xiao Feng, why haven't you gone down yet?"

Xiao Feng stopped, looked around, they were all exactly the same scene, there was no difference at all, he felt that something was wrong, and shone a strong flashlight on the mountain wall on the side.

"Do you feel as if the mountain wall was not carved out by tools, but like ...... Gouged out by the claws of some kind of animal?" Xiao Feng stroked the mountain wall with one hand.

Zhao Xiyue looked at the light of the strong flashlight, and saw that the mountain wall was indeed irregular traces, deep and shallow, irregular, very casual, ordinary tools can not do so rough, basically three depressions are connected together, giving people the feeling that some kind of three-clawed creature is gouged out with its claws, such as chickens.

"Indeed, it looks like a claw scratch" Zhao Xiyue nodded and said, but after saying that, she was stunned, such a big claw dug out such a deep hole, how big that creature is.

In fact, Xiao Feng also had this kind of doubt in his heart, because it was too similar, but he also had deep doubts in his heart, did such a huge creature really exist?

He still couldn't believe it, shook his head, and for now he had to quickly solve the problem of how to go to the bottom.

"Give me your lipstick" Xiao Feng turned his head to Zhao Xiyue and said, with a serious face.

"Ah, why do you want my lipstick?" Zhao Xiyue looked puzzled, why did she suddenly want lipstick, but seeing that Xiao Feng didn't look like a joke, she slowly took it out of her pocket and handed it to him.

"Be careful, I only have one of this color," she didn't forget to tell Xiao Feng.

Seeing that she hesitated, Xiao Feng simply took it, opened the lid directly, twisted the lipstick and drew a big cross with lipstick on the mountain wall, and then closed the lipstick cover with satisfaction.

Because the mountain wall is very rough, more than half a tube of lipstick has been used after painting the big fork, and the rest of the surface is full of dust and stone slag, which must not be used, all of which was seen by Zhao Xiyue, dumbfounded, and even forgot to stop it.

"Xiao Feng, you give me death!"

It wasn't until Xiao Feng handed over the lipstick that Zhao Xiyue was grief-stricken, pinching Xiao Feng's neck with both hands, gritting her teeth, as if she had some kind of enmity, her brown eyes bulging and bulging.

"Stop, stop!" Xiao Feng hurriedly stopped, didn't he just keep lipstick, this woman was really stingy, and hurriedly said the remedy, "I'll buy it for you again, it's okay to buy two, right?"

"Three! or I won't have fun with you!"

"Ahem, three is three. ”

Zhao Xiyue let go of Xiao Feng at this time, but the residual anger on his face had not completely dissipated. Xiao Feng hurriedly led Zhao Xiyue to continue walking, for fear that this woman would settle accounts with him again.

Along the stone steps, the two walked down again for a long time.

At this time, Xiao Feng's eyes changed slightly, and Zhao Xiyue also lost his face, only to see that on the mountain wall a few meters in front of him, it was the big red cross that Xiao Feng had just painted with lipstick.

"We may have run into a ghost hitting the wall. ”
