Lin Xue asked with a puzzled look on her face: "Master, what is the Human Immortal Realm?" Ji Yunsheng explained: "Earth, where we are right now, is just the mortal realm. The cultivation levels in the mortal realm are divided into Qi Condensation, Foundation Establishment, False Golden Core, Golden Core, Nascent Soul, Deity Transformation, Dao Integration, Void Refinement, Tribulation Transcendence, and Integration.
The Human Immortal Realm is the very first realm after Integration. Your parents seem to be in a place called the Central Immortal Realm, which I assume is the Immortal Realm. I am afraid that without the cultivation of a Human Immortal, you wouldn't be able to withstand the Heavenly Dao pressure of another world, which is why I want you to reach the Human Immortal Realm before I take you to find your parents.
It's just that the spiritual energy on Earth is currently extremely thin, so cultivating to the Human Immortal Realm will probably be very difficult. Once we finish eating and head back, I will teach you how to cultivate, and by the way, awaken the spiritual consciousness of Earth's Heavenly Dao in advance. Once that happens, spiritual energy can begin to revive, and your cultivation will become much easier."
