At this extremely embarrassing moment, a "creaking" sound suddenly came into the ears of several of them.

The voice was not loud, but in the empty room, it was extremely clear, as if it was right behind them.

The three of them hurriedly looked back, but found that the sound actually came from the big black coffin.

I saw that the coffin board that was originally on the side of the coffin was slowly closing automatically, perhaps because the years were too long, and the hinge between the coffin board and the coffin made that "creaking" sound.

"How...... What's going on? How the is this coffin still an automatic door? The fat man was shocked.

Gao Chao also felt that his scalp was exploding, and seeing that the coffins had been closed on the coffin board, he was about to let everyone retreat quickly, but before he could shout out, he heard a strange sound in this space again.

There was a loud sound of "click", I don't know where it came from, Gao Chao only felt that the sky was spinning, and in this circular space, the sound was uninterrupted, as if it came from the walls and floor.

Before the three of them could react, the floor of this space began to shake slightly, and the three of them were a little unsteady in shock.

The three of them were frightened by this situation, and they couldn't help but retreat again and again, leaning against the wall, but the wall was also trembling, and slowly changed its appearance.

Gao Chao looked up, only to find that the originally smooth wall had become uneven, and there were rocks slowly sticking out of the wall. The rock rubbed against the wall. Fragmented stone chips fell. The three of them were all over the place.

Gao Chao spat twice at this time, and shouted loudly: "Hurry up and go out, run back and forth!" ”

The space was already shaking, and it was not easy for them to run, so they could only hold on to the wall and stagger back and forth.

But before they had taken a few steps, they had to stop because of the smooth floor. It's changed.

I don't know when the middle part of the floor began, but it disappeared as if by magic, and in its place, it was a circular hole.

This hole is not big, originally it was still hollow and black, but in the blink of an eye, there was light in this hole.

- Green fluorescence!

"It's that liquid!" Gao Chao shouted.

Sure enough, there was a liquid gushing up in the hole, and the liquid. It's the kind of liquid deposit they've found before -- the kind of liquid deposit that glows green.

The liquid kept tumbling, and the level of the liquid was getting higher and higher. Seeing that he was about to emerge from the hole, Gao Chao shouted again: "Retreat!" ”

The three of them didn't care to look at the hole anymore, and stumbled towards the way they came, but before they could run out of this circular space, the corridor that was already in front of them suddenly disappeared somehow.

All of this is like magic.

Fat was lying on the uneven wall, which was supposed to be where the entrance to the passage was.

"Grass, am I having a nightmare, why is this corridor gone in a blink of an eye?" The fat man shouted with a crying voice.

Gao Chao saw that he couldn't run out, and when he looked back, the green liquid had already gushed out, constantly expanding outward on the white shaking floor.

If this continues, if the greenish glowing liquid comes into contact with them, the consequences will be unimaginable.

In a hurry, Gao Chao looked at the surrounding walls, and saw that the stones sticking out of the walls were already half a meter long, and at this glance, it was more like steps.

Gao Chao had an idea, and shouted loudly: "Quick, run up, climb these stones!" ”

There was no way out, and the three of them didn't have time to hesitate, and they had already climbed up the wall along the stones.

And the green liquid was still tumbling and gushing out, and in the blink of an eye, the entire white ground had been completely covered.

The three of them were pressed against the sticking stones, their bodies pressed against the wall, all nervously watching the situation below.

I saw that the green liquid was getting more and more, and after a while, the seven coffins were also submerged.

If this continues, the liquid will probably drown all three of them as well, and it seems that it is only a matter of time.

Gao Chao was worried, but he saw that the surface of the liquid suddenly calmed down for some reason, and slowly, the liquid level began to drop again.

The fat man looked at it and couldn't help but shout: "Look, there are whirlpools on the water. ”

It was indeed good, but some whirlpools suddenly appeared on the surface of the water, and they counted carefully, no more, no less, exactly seven.

When the three of them were wondering, they saw that the seven black coffins gradually emerged from the water, and then looked at the liquid that emitted green fluorescence, which was actually sucked into the coffin by the seven coffins.

"It's those coffins, I'm grass, why does this coffin still have this function?" The fat man shouted.

Gao Chao was also puzzled, but he had an ominous premonition in his heart, there must be something in this coffin that they couldn't think of.

Just when the three of them breathed a sigh of relief and watched the green liquid all flow back into the round hole, the seven black coffins really changed again.

I saw that the coffins slowly shook, although it was not so violent, but it was obvious that the shaking was like something moving in the coffin.

The fat man exclaimed, "How did you do it?" I remember that there wasn't anything in those coffins? How so? ”

Gao Chao "shh

The fat man and Xia Qing were clinging to the wall, and they were both very nervous when they saw this situation.

The seven black coffins trembled, and then suddenly calmed down together, this calm, on the contrary, frightened Gao Chao and them, and the three of them were puzzled, but the seven coffins moved on the smooth floor.

The eyes of the three people were about to pop out, no one could have imagined that these coffins would move by themselves, only to see them slowly slide, and they all moved back to their previous positions, three people, you look at me, I look at you, they are all a little overwhelmed.

But then, the space changed again.

Everything in this space is bright and white, just because there is a circle of lighting devices like light strips above this space, which is always glowing, but suddenly, the light of the light strip becomes flickering and dimming, and it starts to flicker continuously. (To be continued.) )
