Learning about the Earth Immortal Realm

Hearing what the old man said and seeing the ancient looking book that he handed him; Xuan Hao could not help freezing for a short moment before starting to look through it to determine whether or not the old man told him the truth.

This...

Reading through the ancient book, it did not take long before a shocked expression made its way onto his face.

What the old man said was indeed true, the ancient book did contain information on the Celestial Immortal Realm and had part of it written in an unknown language that reminded Xuan Hao of some of the other ancient texts he had encountered from the past.

However, the thing that caught his interest was neither of these two but was instead a detailed explanation of the Earth Immortal Realm that was written at the start of the book. The explanation was detailed and finally gave him an opportunity to understand the mysterious Earth Immortal Realm that had seemed to elude him over the past few years.
