In other words, the reason why Immortals can communicate with higher-dimensional worlds and obtain more mysterious and profound power in this Infinite City is because their ancestors actually stepped onto higher planes. The Immortals say their predecessors transformed into Heaven, so they can receive decrees that only they can hear, which is also a fact.
The Immortals call it "Heaven," the Gods regard it as "Outer Heaven," Da Xuan and humans refer to it as "high dimensions." Whatever it is called, it is an unknown that humanity faces in the process of evolution!
