What is displayed in front of everyone is a three-dimensional spatial structure map.

It is a new, layer-by-layer structure in the shape of an inverted cone, marked with dense text notes and small dots. Explained by the system, Lotta immediately understood what it was.

This is a diagram of the entire El plane!

It's the whole plane!

The top layer is the surface, where you can see a lot of landforms such as vegetation, lakes, plains, etc.

Underground, on the other hand, are urban gathering points.

The entire underground of the El plane has been transformed by the intelligent life forms of ancient civilizations, layer by layer. The more advanced it is, the higher the level of rank. From the map, even the small town of Eyre can be seen, and Lotta tries to zoom in, and a clear projection can be seen. The buildings of the town are clearly visible.

"Original...... The academy has only explored the surface......"

Lucia naturally knew what this structure diagram meant.

"Where we are, it's a control node. There are three above ground and four underground, for a total of seven control nodes.

The entire El Plane has been transformed into a huge fortress by the creatures of ancient civilizations. They operate this plane directly and make a plane journey. Go to other planes, invade or trade, change your spatial position at any time, and wander in the void. Make it impossible for the other invaders to locate the El. It's like ...... Move the castle ah......"

Under the continuous analysis of the system, Lotta gradually understood the existence of the El plane.

By mobilizing the historical database here, you can get a glimpse into the past of an entire ancient civilization.

[They have been to countless planes, through countless wars and invasions, or have visited and traded in friendship. But in the end, it stopped here, and the reason for the fall of civilization is unknown. There is no record in the database at all, but it is inferred from the internal time timer that it has been about 20,000 years, and there is no sign of any activity. 】

Lotta flipped through it and explained it to the rest of the team.

By the way, the projection is manipulated, and those pictures in the history library are released.

Everyone finally meets the creatures of the ancient civilization, a group of cute little creatures, with white skin, baby faces, wide furry ears, and a tail with a ball. It's like a cute doll.

Ellie and other girls are watching the flood of girlish sex.

Lotta had an urge to pinch it.

It's just a pity that this civilization has fallen.

What is left behind is the entire El Plane Ruins, as well as ...... Core energy.

Yes, the core energy of the El Plane.

Heart of El.

The entire El was born without energy because of this. Although the El has fallen, the Heart of the El is still blooming with its own energy and light.

In the research, Lotta suddenly discovered that there was a new record, about 600 years ago.

He retrieved the relevant information.

The name of the data was found, and it was listed as 'thief'.

After opening it, it was found that there was an energy output node in the central area of the Heart of the El. Stolen by alien invasion creatures, stealing El's light with a backward magical technology and clumsy means. Through the rudimentary spatial positioning, the power of the El was directly poured into the invaders' own kingdom in the void. And the thieves are like locusts, constantly eating away at the surface of the lower buildings of the El.

The pillar of light that reached the sky.

It's the energy that has been stolen.

Seeing this, Lotta instantly understood. The so-called thieves, I am afraid, refer to their academy, the guardian of the world.

"It turns out that the pillar of light in our academy is from here......"

Others have understood.

The Little Mermaid was lying on the console, with big beautiful blue eyes, staring at the screen in front of her. There was a blazing light flowing under his eyes, and he muttered to himself:

"I see...... I see...... The power of the Guardian of the World is endless, and it turns out that it comes from here. This is the source of the energy that I thought, I see. ”

"Lucia, are you alright? What are you talking about? ”

Lotta felt that something was wrong with the little mermaid's state, and the blazing light in her eyes made people chill.

"It's okay, but I suddenly understood why the demons couldn't invade the main plane. The source of the power of the dimensional defense matrix in the inner courtyard of the World Guardian Holy City comes from here. ”

Lotta was a little confused.

"What are you talking about? What Plane Defense Matrix? ”

"In the past six hundred years, have you heard of the main plane being invaded on a large scale by other planes?"

Lucia asked rhetorically, and the team members shook their heads in unison.

Ellie, who has lived for 3,000 years, clapped her hands and said:

"Indeed, I remember when I was a child, my parents used to go out and fight, and they didn't care about me. For a while, they came to the house every day to count the gold coins, and they threw away the knights I had worked so hard to collect. That's the quintessence of human civilization that I've spent 700 years collecting! They all threw me away, and they reprimanded me every day to teach me how to be a dragon, so as not to embarrass them. ”

Ellie said, with a sad look on her face, and Jean mentioned the sad thing first.

The corners of Lotta's mouth twitched a few times.

Ellie becomes a 'problem dragon', loyal and obsessed with human dogma and etiquette. Like most of humanity's 'problem children', home education has to be blamed.

After all, human nature is inherently good.

Isn't it?

Lotta also understood a little and asked:

"Is it because of the dimensional defense matrix you were talking about?"

"Yes, the Guardians of the World were officially established from that time. The Plane Defense Matrix is the umbrella of the main plane. She has an infinite amount of energy that protects the entire plane from being locked by large teleportation skills. It also has a terrifying magic array of destruction, destroying those who dare to invade. The three major invasions of the demon race in the recent stage were all shattered by this defense matrix. The same is true for the Void Force, which is simply unable to launch an invasion of the Main Plane. ”

Lucia said, pulling out a small notebook and starting to write.

Lotta shrugged her shoulders and continued to check the library.

"Strangely, this plane has been abandoned. So, who wrote this record 600 years ago? ”

The questions he asked, no one could answer.

The system gives some information.

[The provenance of the document is famous, and it comes from the lowest area of the underground interior. And, pay attention to the details, there is a small town of El on the map. Indicates that the map is always synchronized, and there is no automatic update mechanism here. According to the data, the total database was updated 5 years ago. 】

That is to say...... Is there anything moving in the depths of the El? ”

Getting this inference makes Lotta creepy.

In the ancient ruins that have been abandoned for 20,000 years, there are still living creatures, so what could it be?

"I think it's better for us to get out of here."

Lotta closes the map and orders the system to erase the traces of the hack.

"Don't close it, I'm finally in."

Lucia babbled, grumbling dissatisfied.

Lotta glanced at her small notebook, which was drawn with a three-dimensional picture just now. This made him frown, and he didn't know what Lucia was doing.

"The Demon Race and the Void Power have always been the source of the power of the Kaixu Plane Defense Matrix, but they can't be found no matter what. Lotta, we're making a big discovery. ”

"Alright, don't look, don't look, run. I feel bad. ”

Lotta drove everyone away, but in an instant, she thought of something that made her hair stand on end.

"Lucia."

"Huh?"

"You...... How do you know so much? ”
