Did the world end today?

Chapter 327 High-Dimensional Broadcasting Project
"What exactly does 'completing the closed loop' mean?"

Lin Xu looked at the grassland in the distance, which was being blown by the wind like waves, and for a moment he was in a daze.

This is still Earth, but it's completely different from the Earth he's familiar with.

Just as Jiang Xingye said, this place is more like a meticulously designed "integrated work area".

Not only its "functionality," but also its "appearance" and "landscape" have been meticulously crafted.

This is a vast "garden," the largest "man-made scenic area" ever created in human history.

Its scale far exceeded Lin Xu's imagination.

But for humanity in this era...
This seems to be the result of their casual actions.

"To understand the concept of a closed loop, you must first understand how the world is structured."

“You should have already seen some worlds in a ‘perpetual superposition state’, and the form of such worlds can serve as a good example.”

“‘Dimension’ is a concept larger than ‘world’, and ‘world’ is a concept larger than ‘universe’.”

"In fact, the entire visible world is a layered pyramid structure."

"In the highest dimension, the world is unique, there is only one."

"As the dimensions continue to decrease, the world continues to differentiate, and after decreasing to three dimensions, it differentiates into countless different worlds."

"However, if we trace back to the fourth dimension, the number of worlds decreases dramatically, to the point that for us, beings accustomed to three-dimensional intuition, there is only one."

"Because in four-dimensional space, time is meaningless."

"In three-dimensional space, the differentiation of the world is based on time."

"Therefore, you can enter different worlds through higher-dimensional channels—and therefore, you enter different 'three-dimensional worlds,' not different 'four-dimensional worlds.'"

"You shouldn't have any problem with that, right?"

"No."

Lin Xu shook his head and replied:
"This is the same as my intuitive perception."

Ayana's ability to absorb information from different worlds through the "lighthouse effect" in higher dimensions confirms the structural relationship between "world" and "dimension".

But what does this have to do with the so-called closed loop?

"go on."

Lin Xu asked:
"If the world in three dimensions has already differentiated into countless independent and unrelated worlds, then what exactly is a closed loop?"

"The closed loop itself is for humans who have already adapted to four dimensions."

Jiang Xingye explained:

"As I said before, the people of our world have sent a message to your world."

"At this moment, we no longer know the specific form this message takes, but you should know very well that this message led you here."

"But have you ever thought about this question?"

How did we reach the fourth dimension?

what?
After he finished speaking, Lin Xu froze on the spot.

"Didn't you discover the technology for dimensional ascension, and reach the fourth dimension by using limiters and solving the problem of adaptability to higher dimensions?"

This development path is consistent with and reasonable to the development path of the world he has experienced before.

But judging from Jiang Xingye's words
Lin Xu seemed to sense something different.

"Yes and no."

Jiang Xingye shook his head as expected.

"To understand this, we still need to think in a lower dimension."

"Suppose a two-dimensional civilization were to ascend to a three-dimensional world, would the inhabitants of that civilization truly be able to adapt to life in three dimensions?"

"In fact, it's not possible, because a two-dimensional entity cannot be directly stretched into a three-dimensional entity after entering three dimensions, right?"

"They can only exist as a 'plane,' suspended in the three-dimensional world."

"However, they possess the ability to travel along the Z-axis in a three-dimensional world."

"And if they want to form a truly three-dimensional civilization, what do they need to do?" Lin Xu pondered for a moment, then answered:

"They need countless, even infinitely many, two-dimensional civilizations to be superimposed and pieced together to form a three-dimensional world."

"Yes."

Jiang Xingye nodded.

"It's the same from three dimensions to four dimensions."

“We need countless three-dimensional worlds to be superimposed on the axis of ‘time’ to piece together a true four-dimensional civilization.”

"That kind of 'four-dimensional civilization' is the real four-dimensional civilization."

"Otherwise, we are just a pseudo-four-dimensional civilization that can only move back and forth on the 'timeline' that has already been traversed."

"understood."

Lin Xu
"But you still haven't talked about the 'closed loop' part."

"It'll be there soon."

Jiang Xingye sat down on the grass and continued:

"Now, let's go back to the original question."

How did our world reach the fourth dimension?

"In fact, nobody knows."

"We are like a passive flicker in four-dimensional space, appearing here inexplicably."

"We don't know where we came from, nor where we are going, because our world is being swallowed up all the time—the timeline of our activities is getting shorter and shorter."

“We know that our ‘pseudo-four-dimensional civilization’ has sent you a message. We know how this message works, but we don’t know where it came from or how to control it.”

"The reason for all this 'unknown' is that we are 'missing' those component 'arcs' that make up the loop."

“You need to help us complete these 'arcs'.”

"Only when these arcs are filled in can our civilization be complete."

"Only when higher-dimensional civilizations are complete can our existence, and the foundation of the entire 'fourth-dimensional civilization,' be complete."

"Only when we don't know the mystery can it be solved."

"understood."

Lin Xu nodded thoughtfully.

In that sense, Zhang Liming's thinking has truly reached the edge of "dimensional ascension".

He once tried to tear apart the veil of all worlds and merge countless worlds together.

If he really succeeds, wouldn't that mean he has achieved "dimensional ascension" in that world?

Unfortunately, he ultimately fell short.
-
But it doesn't matter anymore.

The important question is, what exactly do humans in this world need to do?
"We've reached the final step, haven't we?"

Lin Xu looked at Jiang Xingye and asked:
"I understand everything you're saying now. The question is, what do you need me to do?"

"I mean, specifically, concretely, what needs to be done?"

"It's very simple."

Jiang Xingye replied:

"I need you to find the simplest message that can propel the world to a higher dimension."

"Once you find this message, we will use all our resources to broadcast it throughout the entire four-dimensional space."

"The requirements are very simple."

"We demand that even if the humans in that three-dimensional world are still living in caves, they can achieve dimensional ascension before the end of the world after receiving this message."

"We call it the High-Dimensional Broadcasting Project."
