The whole world of cultivation is like a vast cosmos, innumerable realms spread across it, each different from the last. So the question came, how could they all interact with each other? Of course, there's the choice of traveling between the realms, but it could only be done by the ones whose strength has reached its peak.
There's also the use of treasures and other such ways, but if their cost was too much, then how would they all interact? Especially the younger ones? The world of cultivation was never lacking in technology, it's just that the truly superior ones could only be seen in the third realm or S-graded realm or higher.
Realms can be graded from G to SSS+, each having a minor division of + and - between them. There's even grading for each species too, and among them, the ones leading the most in technological advances are the Techno race, one born from metals, and they are superior in the regard for the hunt for new theories and techniques.
