Speaking of the cultivation system of Four-Dimensional Space lifeforms, we first had to start with the Three-Dimensional Space lifeforms everyone knew best.
In Three-Dimensional Space, there was one and only one cultivation system: Psionic Cultivation.
Whether it was body tempering, studying spells, or training Psionic Energy... all these different paths ultimately led to the same destination: the cultivation path of "absorbing and controlling psionic energy."
By continuously refining psionic energy, Three-Dimensional Space lifeforms achieved explosive leaps in power, progressing from ranks one through eight to Planetary-level, then Star-level, Nebula-level... gradually becoming mighty powers in their own right.
Four-Dimensional Space had a similar cultivation method. The lifeforms there advanced by absorbing a type of energy called "Aether," steadily growing stronger.
But beyond personal cultivation, the ruling class of Four-Dimensional Space had another cultivation method: "Civilization Binding."
The term "Civilization Binding" sounded somewhat abstract. But it was actually exactly what the words implied: binding everything about oneself to the civilization one belonged to!
For example.
If Su Yu used this cultivation method and completely bound himself to Blue Star Civilization, then his own strength would be determined by Blue Star Civilization's rise and fall.
Once the binding succeeded, Su Yu and Blue Star Civilization would become a Community of Fate.
At that point, Su Yu's strength would also be determined by Blue Star Civilization's prosperity.
If Blue Star Civilization remained at its level from two years ago, Su Yu would probably possess only God-tier Lower strength;
If Blue Star Civilization developed to the level it had reached before going to war with Skrull Star, then Su Yu would definitely possess God-tier Peak strength!
Thinking even bigger.
If Blue Star Civilization could spread across more than a dozen nearby stars, Su Yu would qualify to advance to Planetary-level; if Blue Star Civilization could
