"Coco, be careful."

"Hey!"

Coco responded, then rushed forward and disappeared.

Xu Xin's hearing is now very strong and she can hear its position, so she doesn't worry about it having problems.

Moreover, this little guy's sense of crisis is much stronger than him.

He groped forward.

The surrounding vines were all ordinary vines, very smooth to the touch, and also had a tinge of heat, which surprised him a little.

This vine is actually still hot!

"Hey!"

At this time, Coco's cry came from the front, and Xu Xin quickened his pace.

"This is……"

What he saw was very different from what he imagined.

Before coming in, he thought there would be a big space in the vine bundle, but now...

He seemed to be in the middle of this bunch of vines, but here...

It's actually just a very small, narrow place.

Only about two square meters?

That's right, a space of only two square meters.

Looking up, the height is quite high. I don’t know how many meters it goes up.

Here, it seems to be a hollow center of the vine bundle.

He thought about the vine bundle being hollow, but this hollow...

It’s a little too thin!

"Hey!" Keke scratched the ground here with his little paws and looked up at Xu Xin.

"...You want me to dig up this place?" Xu Xin raised her eyebrows.

"Hey!" Coco nodded her little head.

Was it actually dug up...

He initially thought that he would explore the inside of this vine bundle and maybe even climb up, but he didn't expect that he would still have to dig down?

We are obviously already in the underground world, do we still want to continue...

But he still believed in Coco, and the place was surrounded by vine walls, and there was nothing else he could do except dig down.

Xu Xin took out a steel shovel and dug into the ground.

Then……

"Qiang!"

Before digging twice, he heard the sound of the steel shovel colliding with metal.

Metal door again?

Without saying a word, Xu Xin removed the thin layer of bluish red contaminated soil.

Under the soil, there is a metal platform buried.

That's right, it's not a door with a handle, but a smooth metal surface less than one square meter.

He dug around again, and there was dirt all around.

By the way, this smooth metal surface looks a bit familiar...

He squatted down and reached out to touch the metal surface.

[Survivor Gravity Mechanism: Survivors can trigger the mechanism by standing on it. 】

Good guy, it is indeed a gravity mechanism!

However, the introduction did not say what this mechanism will trigger.

Xu Xin picked up Coco, hesitated for a moment, and then stepped on it.

"Card!"

There was a crisp sound under the feet, and then the mechanism under the feet began to slowly sink.

Then, the speed of descent suddenly accelerated!

Xu Xin's expression changed, and just as she was about to kick her feet up and jump up, there was a "bang" sound, and the mechanism had stopped.

And he has already fallen below the ground of the underground world!

He looked up and saw that the mechanism had fallen not far away, only about five meters.

This tells him that he can jump on it at will now.

Heaving a sigh of relief, Xu Xin began to look around.

In front of you is a passage.

A square passage made of metal, almost three meters high and wide.

And on both sides of the passage, there was actually...

It’s a door with iron bars!

That's right, this looks like a prison corridor!
