The Primordial Martial Realm was not particularly large, divided into a total of ten trillion layers, each layer possessing only the volume of a multiverse.
However, these ten trillion layers of realms were not parallel dimensions. Instead, they were interconnected in a way that their essence progressed from low to high, while their volume remained unchanged.
Simply put, a powerful being in the first layer, who could destroy countless universes with a wave of his hand, would find himself exhausted after running a few kilometers upon ascending to the second layer, despite possessing countless inner universes and inner heavens as vast as innumerable universes.
In the second layer, only those whose inner heavens reached the multiverse level could survive.
A cultivator capable of destroying tens of trillions of universes would instantly explode from the air itself upon ascending to the second layer.
This was because every wisp of air, though small in volume, possessed immense mass and a high essence, equivalent to the gravitational mass of tens of trillions, or even more, universes.
Inhaling such air without sufficient strength would be fatal.
In the second layer, to achieve the power to destroy universes, a martial artist's inner heavens would need to reach at least the level of an infinite multiverse.
Within each realm, Lin Xingyuan had set ninety-nine cultivation realms.
Lin Xingyuan enthusiastically explained the rules of the Primordial Martial Realm to Fumeng.
Each layer of the realm contained ninety-nine major realms.
After a martial artist cultivated to the ninety-ninth realm, they could ascend. Upon entering the next layer, they would discover that their achieved ninety-ninth realm was not the end. In this new realm, there were new ninety-nine realms!
They would need to advance another ninety-nine major realms to ascend to an even higher layer!
And there were ten trillion such layers within the Primordial Martial Realm!
Ten trillion realms requiring ascension!
A total of nine hundred ninety trillion realms!
Fumeng was dumbfounded at the time, exclaiming, "With so many realms, how can one possibly reach the end?"
Lin Xingyuan smiled and said, "I never intended for them to reach the end!"
"Once the Infinite Box is cultivated and Infinite Energy is achieved, the realms spoken of by cultivators are merely things I can set at will."
"As the Ancestor of the Primordial Martial Realm, I passed down the Yuan Qi Martial Path and thus divided it into nine hundred ninety trillion cultivation realms..."
"The realms are determined by me. All cultivators within the Primordial Martial Realm must practice according to my martial path cultivation methods."
As soon as Lin Xingyuan finished speaking.
Fumeng watched as, in the highest layer of the Primordial Martial Realm, the tenth trillionth layer, a cultivator who had reached the nine hundred and ninety trillionth realm, his martial aura shook the heavens, unleashing power equivalent to nearly tens of trillions of boxes.
He was about to transcend!
He was about to transcend the limitations of this Primordial Martial Realm!
"Nine hundred and ninety trillion realms!"
The martial artist wept!
"I have ascended through trillions of realms and cultivated for nine hundred and ninety trillion realms. Finally, I have cultivated the Yuan Qi Martial Path to its end!"
"Today, I shall forge a new path for martial arts! Surpassing the Creator's limitations!"
The martial artist began to ascend!
He was already in the topmost layer. Ascending from here meant transcending the limitations of the Primordial Martial Realm and entering the Void Sea!
Fumeng, outside the Primordial Martial Realm, in the Void Sea, watched this scene with a strange expression and said, "He is about to ascend!"
"Your Primordial Martial Realm has no higher layers. His ascension means transcendence, and he will directly transcend into the Void Sea!"
"With such a powerful being entering the Void Sea, countless worlds in 'All Heavens Flow' works will tremble because of it!"
Lin Xingyuan shook his head and said, "He cannot transcend! Nor can he enter the Void Sea! My Primordial Martial Realm is not at the level of a finite box, but an infinite box..."
"Ascension? The Primordial Martial Realm will automatically create a new layer for him to ascend to his heart's content."
"And new ninety-nine realms will also meet him."
Fumeng looked.
As the martial artist ascended, the Primordial Martial Realm had automatically added another layer.
Ten trillion layers plus one!
The martial artist looked at the new layer and felt thousands of trillions of auras superior to his own. He let out a cry of despair.
"No!"
"According to calculations, ten trillion layers is the highest! How is it possible that there is another layer above the tenth trillion layer?"
"I have once again become the weakest in this realm! In this upper realm, even a single venomous insect could kill me!"
"No! No! No!"
The martial artist stomped his feet in panic.
Then, he forcibly calmed himself, consoling himself, "It must be a calculation error! It must be a calculation error!"
"Before, I must have miscalculated one layer!"
"As long as I cultivate another ninety-nine realms in this new layer and ascend once more! I will truly break through the limitations of the Primordial Martial Realm and enter the Void Sea!"
...
"Do you see?"
Lin Xingyuan said, "This is the marvel of the Infinite Box, and the marvel of Infinite Energy."
"Although the Primordial Martial Realm previously had only ten trillion layers, with the tenth trillionth layer being the supreme realm!"
"But as long as someone attempts to transcend, the Primordial Martial Realm will automatically create another layer above the original supreme realm!"
"If he ascends fifty times, fifty new upper realms will appear. If he ascends fifty billion times, five hundred billion new upper realms will appear!"
"There will always be a higher layer!"
"The number of layers is always n+1."
"Does the Great Dao have an end? As a cultivator at the Infinite Box level, I can confidently say."
"If I want the Great Dao to have an end, it will have an end. But if I want the Great Dao to be endless, it will be endless!"
"What is an endless Dao?"
"This is an endless Dao!"
Fumeng was stunned, then whispered, "How is the Infinite Box cultivated?"
"How can one reach the Infinite Box?"
"Following this method of ascension, no matter how many realms one cultivates, it is impossible to reach the Infinite Box!"
"It will always be a finite box!"
Seeing this, Lin Xingyuan took out a copy of "The Method of Cultivating Infinite Energy."
And gave it to Fumeng.
Then he said, "It is impossible to cultivate the Infinite Box through normal means. That is certain for Infinite Energy!"
"But it can be achieved through abnormal means!"
"This 'Method of Cultivating Infinite Energy' was passed down from the sermon of a Profound Immortal from the Supreme Primordial Era."
"That Profound Immortal from the Supreme Primordial Era has already attained the Dao of Supreme Profound Immortal. Even an Infinite Box level expert is inferior to his slightest divine thought!"
"You can study it."
Fumeng took the "Method of Cultivating Infinite Energy" and intended to cultivate it.
However, no matter how hard he tried, he could not understand it... nor could he see through it...
Lin Xingyuan, watching this situation, was perplexed, "This is not right! How is it possible that he cannot see through it? That Profound Immortal explained it very simply and clearly..."
