Among these, the majority of planes were undiscovered by the many forces of the Main World, especially those rich in resources and abundant in products, which were like undeveloped virgin lands that all forces eagerly competed for.
Of course, there were also small worlds that had been occupied by some Transcendent forces, especially by the Church of the Gods and the Evil God Church. Essentially, each force had such small worlds, serving as their own strongholds or retreats.
Before the fall of the Phillips Crystal, the passages to these small worlds were controlled by those forces themselves, without interfering with each other, but the Space channels opened by the Phillips Crystal were also connected to these worlds.
Now that stirred up the hornet's nest, and when many hostile forces discovered this issue, they naturally wouldn't turn a blind eye.
