When these "encrypted" intermittent words were read word by word by the ravens who were also frowning, everyone felt at a loss.

However, this thing is clearly the work of a person who has done a certain job here, and this person, out of good habits, has taken daily work notes! This cleared up a small part of their confusion for the raven.

And as a guess, they must be doing some kind of difficult secret experiment here!

Although this book is no longer decipherable, it also provides some means for those who later see this note to understand what happened here.

If you can go out, be sure to find someone who understands and study the contents of this note.

The chief scientific officer of that sloppy master looks like a good candidate!

Raven couldn't help but think so, and slowly closed the notebook.

"Hmm...... Doctor! The word doctor is mentioned again...... What is a Ph.D.? ”

Raven repeated it several times as if he had fallen into a magical obstacle.

He carefully put away the broken book, turned to look outside the glass again.

"Huh? …… Look! Is that a bright light or something? ”

Raven pointed to a place......

The people who were probing around the room turned their heads to look.

“……”

Sure enough, some light and shadow were swaying slightly, and they were revealing from that far distance, where they couldn't see clearly! But that's too faint...... And only people like them, who have been groping in the dark for a long time, can recognize it!

There is light?!

What does this mean? Is there lighting or energy supply in that place?

Eventually, they identified the source of the light.

It was only after they reached a larger hall that they could see where they were.

Directly in front of the hall was a 6-corner transparent glass window, Wang Hu reached out and touched the glass, which was quite strong! And it's obviously made of special materials, so thick to the touch that it feels like you're touching a wall.

Looking out of the window, a group of people saw a large pit about 30 meters in diameter in the open space below, or a large pool!

The pool was surrounded by a steel platform, also hexagonal, with cables connecting the machines and equipment on several sides of the platform.

If those dim lights are the reflections of the water! So where does the reflection in the water come from?

The answer, apparently, comes from somewhere above the pool.

There's nothing to think about, there must be a light source somewhere above the water! They felt the need to investigate. If there is light, it means that the lighting equipment is still working, and there is still only one way in front of them, out of this hall and down there!

The hall was still full of machines, neatly arranged but dusty, and in the center of the hall there was a platform that looked like a table overlooking the whole hall, made of metal, with a ring of steps around it, and a handrail on the platform.

It's like there was once a commander who had to give orders and supervise the work of those who operated the machinery and equipment below.

What a strange place!

"There's a staircase here!" One of his men shouted.

Outside the hall, a staircase led down, and soon the crowd came to the square where the pool was.

Below, everyone could see more clearly, there was indeed a shiny round object "floating" on top of the pool!

The round object that reflected the swaying light was completely undiscernible for what it was for, but it reflected the light onto the surface of the water like a cold moon, and the pool spread the light from the water to the periphery.

"What's that?"

Chen Liuwang asked suspiciously.

"I don't know...... Maybe we should take a look around here to see what else we can find, and maybe guess what this empty square is for? ”

Old Man Su shook his head......

So the crowd began to look around.

The actual boundary of the square is not too large, about 150 meters long from east to west, about 200 meters from north to south, and the whole is about an irregular oval. The "floating" object at the top can probably be seen in their light!

It was a flat, round capsule made of some kind of metal and glass - or container, but I don't know why it was in mid-air!

"There's an entrance here!" One of his men shouted in a low voice.

It is a staircase that can only be climbed up and built along one of the walls of the hall.

"Let's go...... Go up and have a look! Raven was the first to step up.

The staircase spirals upwards around a large pillar in the middle. When everyone walked up about 20 meters, it was almost parallel to the oblate cabin, and everyone could see it more clearly.

The thing was connected by a round, small grinding disc.

Above the grinding disc was a cylindrical connection to six long mechanical arms, which were also more than 20 meters long, extending from different directions to hold the container.

So it was supposed to be in the pool?

Turning around the top of the staircase, less than 30 meters high, a simple passage along the wall is revealed.

"Bang Dang Bang ......" made a sound when walking on it, and it must be an iron bridge made of steel that resembles a gangway.

The square, which is 30 meters high at their feet, doesn't look big at the moment! In addition to the faint light reflected off the water, the hexagonal glass buildings they walked through were faintly illuminated.

If you look closely, the light must be shining in from somewhere above their heads. There might be other ways to go, but they all decided to take a look at the iron bridge first.

The section of the road built along the cave wall is not long.

After a few minutes, steps appeared at the front of the road, and the source of the light could finally be seen diagonally above them!

It was a flat, long hole, a few dozen meters away from them, a recess in the wall of the cave, probably dug out by hand.

Because the light at the entrance of the cave clearly reflected the regular rectangle, and it was very smooth, and the light and shadow from it were all around, like the light of fire reflected on the surface of the water.

Chen Liuwang glanced back at the oblate spherical container, which was still hanging there, and that position was diagonally behind them.

Looking at it from this angle, you can see that there are clusters of cables connected to a device on the wall of the cave.

"What the hell is this place for? I don't understand, why is it so complicated? Old Man Su shook his head and said.

"Surely the previous people used to do what research, those doors and locks...... Apparently I don't want people outside to see it! ”

Chen Liuwang said as he stared at the rectangular hole.

“…… Maybe they don't want the people inside to go out. Raven said.

He pondered a question all the way - what was the matter with the woman's voice saying "Dr. Sue?"

Although he had some kind of hunch, he wasn't sure why, the moment he put his finger, the voice seemed to say to himself, and the door opened.

"The lights are shaking! Don't you think? Old Man Su narrowed his eyes and observed carefully for a while.

"Hmm...... Like a firelight? But ......"

"Looks like someone lit a torch in the water!"

"That's right, those ripple-like flickering spots of light seem to come through water or clear crystal!"
