Yu Hua had many questions, but she chose the one she cared about most to ask, "Elder, why are you chasing the Immortality Pill?"
"Didn't Qingcang tell you?" The elder looked puzzled, then answered briskly, "This item comes from the Immortal Realm."
Yu Hua's eyes widened slightly in confusion, "Does the Immortal Realm truly exist in this world?"

If the Immortal Realm truly existed, why would those Immortals who have lived for countless years still occasionally reveal themselves in the Cultivation World?
