The battle situation where the Taixui Demon Tree destroyed the aircraft carrier fleet has already spread far and wide.

The nearby city-states and naval bases have rescue duties.

Among them, the nearest and most capable is the Life Research Institute.

It is located in the doldrums near the equator in the Pacific, between 5° north and south latitude.

Here, the sea is calm and tranquil, but beneath lies a secret base, which is the Navy's Life Research Institute.

Its main research subjects are the modules of Radiation and Radiation Beasts, and it frequently captures members of the Jiyi Army to explore the mysteries of the Moon's Eye and the like.

Guarding this place are two Navy Admirals, both of whom are Divine Level beings who have completed dimensional upgrade.

However, the places where they usually reside cannot be seen by people.

Or perhaps it should not be expressed in a three-dimensional coordinate system, but in a four-dimensional one.

Relative to where humans live, it belongs to another plane.

Yes, another plane, that is, other three-dimensional space-times on Earth.

This is not another universe or some mystical place; it simply coexists with everyone on the 'same Earth', basking in the light of the 'same Sun'.

It's just that humans and everyone else on Earth are three-dimensional creatures, so they only live on the 'most superficial layer' of Earth's corner.

If the Four-Dimensional Earth were a book, then all things from billions of years of life evolution throughout history are on the 'first page'.

Until the birth of Emperor Ran, who was the first to undergo a dimensional upgrade, which turned Earth's history to the 'second page'.

Then came the third page, fourth page... Upon becoming a four-dimensional being, one can overlook all these pages.

Emperor Ran traversed every corner of the Four-Dimensional Earth, completing the feat of 'Circumnavigating the Four-Dimensional Earth'.

Ultimately determined, the radius of the Four-Dimensional Earth is still 6371 kilometers.

The circumference is 40,030 kilometers, even slightly smaller than that measured by the three-dimensional Earth, proving that from a four-dimensional scale, the universe has curvature, and it is convoluted.

But this is a hypersphere of a four-dimensional structure.

Its super surface area is about 511 trillion 'cubic kilometers'.

The numerical value happens to be a thousand times what humans have measured, but the 'area' unit is expressed in cubic kilometers.

Because its surface is composed of individual three-dimensional Earths, the entire Three-Dimensional Earth, as understood by humanity, is just one aspect of this super sphere.

If a four-dimensional being stands in space to view the 'front' of this Earth, the fragment he sees is itself a three-dimensional sphere, i.e., the entire Earth as recognized by humanity.

Indeed, it is an entire whole.

Meaning that from one angle, you would see a complete map of the world and nations such as Asia, Europe, the Americas, Australia, Africa, Antarctica, and the North Pole...

If desired, one could even perceive the Earth's crust, mantle layer, and core.

Such a perspective covers nearly one-fifth of the 'super surface area' of the Four-Dimensional Earth.

Of course, given that humans are accustomed to living on a flat plane, when the Divine Level later drew the 'Four-Dimensional Earth Map', it only recorded the geographic information of the four-dimensional surface, i.e., the part directly exposed and unshielded under four-dimensional sunlight.

This approach effectively compresses the information back into a flat plane measured in 'square kilometers', as units.

After all, many places are simply not meant to be visited, or used. For instance, an entire plane of just seawater, or entirely composed of mantle or core regions.

Thus, reducing the map from super surface area to surface area makes it easier to understand for those in the Supreme Council, while being much simpler and more practical. They called it 'Plane Transformation'.

This allows for the creation of a 'Plane Map' with an area a thousand times that of the 'World Map'.

When comparing it to mankind's global map with seven continents and four oceans, it is only the thousandth fraction corner of that map.

But because it is the place of human origin, it was drawn right in the center of the map, as the main plane at the zero-degree coordinate, also called the Main Plane.

At this moment, this map is in the hands of a man dressed in white.

Of course, he is not holding it but rather, the images of the map are etched in the lines of his palm.

He does not need to move his eyes to know all the contents.

It seems this man noticed something, and suddenly landed on a vast glacier.

In an instant, the surface of the glacier cracked and melted with a roar, revealing a cavern larger than an island.

What lay beneath was not ice but an ocean.

"The map is wrong here, how could the Antarctic Sea be marked on the 57th page plane? This plane shouldn't have an Antarctic."

"Were the Dishida nobility really focusing on mapping work properly?"

"They can't even tell the difference between ice-lake and Antarctic glacier? This is just a small portion of a frozen sea, don't they know it's winter here right now?"

"Entrusting them with surveying work is truly laughable."

He was very angry, with a face full of displeasure.

"Those guys are here to have fun, and we still have to be responsible for sending them back. Xiao Yaomu, are you really here for inspection?"

At this moment, another shirtless man descended; his muscles knotted, and images of mountains and rivers appeared on his wrinkled skin.

The complexity of both their appearances and skin textures was a fitting illustration of information overload, exceeding even the combined information of a mountain range and forest.

Mere mortals almost certainly couldn't perceive their entirety, and trying with force would likely render their brains into incoherence from the information deluge.

The white-clad man named Xiao Yaomu sneered, "Even if the survey is improperly mapped, shouldn't they at least manage to hand it over?"

"Measurements, scans, and processing are handled by the AIs, how could such a basic mistake as recording an ice-lake as the Antarctic occur?"
