It sounded like something had fallen to the ground.

Because of our preconceived notions, we thought that there was no one in this building, at least there were no living people, so this sound startled several of us.

Liu Yong looked like he was about to pee his pants, but he didn't shout because I blocked his mouth with a cloth.

We all waited for a while, but it never came again.

"What's that?" I couldn't help but ask.

"Just go up and have a look. Then he saw the moon spirit walking towards the staircase.

I hurriedly pulled her down: "Wait a minute!

"No wait. Yue Ling said: "It's useless to wait any longer, do you still expect him to come down by himself?"

Then I saw that the moon spirit really walked up, looking fearless.

I knew that there was something wrong with the spirit of this moon spirit, and I was afraid that she would have an accident if she went up recklessly, so I hurriedly pulled Liu Yong to follow.

Lin Hai and Hu Ziming also followed.

It seems that only the fourth floor is an "office area", because the structure of the fifth floor has changed again.

In other words, the fifth layer has no structure at all.

The entire fifth floor is a large room of 1,000 square meters without a shield, with only a few thick load-bearing columns blocking the view.

But the facilities on this floor caught our attention.

What caught our eyes were more than twenty stone platforms, which were evenly distributed on the five floors, and this did not seem to be ordinary stone platforms, and I always felt that their shapes were a little panicked, but I could not tell what scared me. Each stone table is also attached to the side of a small stone table, which is also fixed to the ground, and this small stone table has some grooves, which looks like it is used to place utensils or something.

I walked over to the nearest stone platform, touched it with my hand, and found that it looked very hard.

I didn't understand what these stone platforms were for a long time, and in the end it was Lin Hai who woke me up with a word.

"Look...... Does this look like a laboratory bench?" said Lin Hai.

As soon as he said this, I found that it should be ** not far from ten, not to mention that there is also this kind of small stone table with grooves on the side of this stone platform, I can almost imagine the scene before here.

"What is this experimenting on?" I asked, confused.

"Do you still need to ask?" said Yue Ling, "Of course it's human." ”

Then I saw the moon spirit lying on her back on the stone platform.

Now I know why I felt that these stone platforms were terrible just now, but I saw that after the moon spirit lay down on his back, he just filled the entire area of the stone platform.

This stone platform is a lying man!

But where did that "bang" sound come from?

I looked around closely, but everywhere I looked was the stone platforms.

The stone platforms are solid, and they don't look like they can make a "pop" sound at all, and it's impossible for a person or animal to hide under the stone platform, unless the creature can penetrate walls......

Yue Ling had already come down from the stone platform at this time, and she actually asked us if the stone platform just now was suitable for her figure.

Forehead......

"Do you want to be experimented on?" I asked, surprised.

"It's useless to think about it, the people here are all now. Moon Spirit's answer always surprises me.

"But there was a noise just now. ”

"Let's look again, maybe it's from some kind of device. As she spoke, the moon spirit continued to walk forward.

The rest of us also dispersed, and I tied Liu Yong to the edge of a stone platform, and then I also began to look for it.

A few minutes later, just as we were about to give up, we suddenly heard another "thud".

This time the voice was close at hand, coming from behind me!

I hurriedly looked back, and just in time to see a slender iron pillar rising to the ceiling, and at the end of this iron pillar was a round ball the size of a duck's egg, and the "bang" sound just now came from this thing.

Yue Ling, Lin Hai, and Hu Ziming all came around.

The moon spirit is really right, it is really the device that makes this sound.

My first reaction was that someone was operating the device above our heads, but Lin Hai told us to be quiet and listen carefully.

Soon I heard the sound of gears closing.

"It's electric. Hu Ziming said in surprise.

Electricity!

If there is one thing that is most precious on the island besides food and water, it is electricity!

That means there's definitely a generator around here!

But the light bulbs in this room are not lit, are they all broken? Or is this generator only powering this one device?

"What is this thing for?" I climbed onto the stone platform and reached for the iron ball, but the iron ball should have completely retracted above the ceiling by this time, and at first glance I thought it was a light bulb, which is why we didn't find it in the first place.

I looked at the other ceilings and couldn't see anything like it.

This device is really weird enough, it doesn't look like a trap mechanism, and even such an iron ball the size of a duck's egg can't kill people, is it used to cooperate with these small stone platforms?

But that's not right, if you want to cooperate, why only get one?

We studied for a long time and couldn't find out what the device was for, so we had to go up to the sixth and last floor.

But this last layer is completely empty.

Weird.

Du Yue said that their people lived here, but this place looked like a place that no one had been to for a long time, but there was electricity.

If this place is safe enough, then it seems like we can make this a new camp, at least guarded by natural walls, but much safer than my fence, and we don't have to spend the night in a cave like primitive people.

I immediately told Lin Hai about this idea, and Lin Hai said that the idea was good, but now the fundamental problem has not been solved, and we have to find out those weirdos quickly.

I nodded, and we all headed downstairs.

By the way, while we were talking, the device just fell down again, and it seemed to be a circulating device with a fixed period.

After going downstairs, we still felt that we couldn't leave this small building so easily, and then Hu Ziming suddenly put forward an idea: "Such a big building, there should be a basement, right?"

I just realized that yes, there should be a basement, but when we went up the stairs just now, we didn't notice a staircase leading to the underground.

However, the structure of the buildings in this place cannot be inferred by common sense, so we decided to look around the first floor again.

After looking around carefully and still finding nothing, we ran outside again and started to look for it.

After searching for nearly two hours, just when we were all a little impatient, we saw a wild goat suddenly run out of the building.

The wild goat looked a little embarrassed, with messy hair on its body and half of its horns broken. It looked a little like the blind bear and the wild boar I had seen before, and it was obvious that they had been abused, and I immediately looked over the neck of the goat, and sure enough, I saw an iron nameplate.

The wild goat immediately winced at the sight of us, as if it had suddenly seen a predator such as a tiger and a lion, and then saw its head shrink and return to the building.

I was sure that I had never seen the goat in the building, so I immediately shouted, "Catch up!"

A few of us immediately chased after it, and I thought to myself that since this wild goat appeared out of nowhere, it must have been hiding in a place where we had not set foot before, so this place was probably a basement.

After rushing in, I happened to see the wild goat rushing into the corridor on the left, this corridor is also the first place we searched after entering the building, I accelerated the speed of my feet and continued to run forward, only to see the wild goat run to the end of the corridor, and suddenly turned to the side, and disappeared!

I hurriedly followed, just in time to see that the wall on the side was still shaking!

"There's a secret door here!" I cried.

But before I could finish my sentence, I felt like my feet were empty, and then my whole body fell downward.
