Upon hearing Sun Zhe's words, Little Dragon Girl recalled carefully, showing great patience, and slowly said, "Immortal Dew can only possibly appear in ancient tombs over a thousand years old."
"And it must be an emperor's tomb."
Sun Zhe was surprised, "Those conditions are quite harsh."
Little Dragon Girl continued, "Moreover, it must be the kind of emperor who achieved the cultivation realm of Spirit Gathering while alive."
"After these emperors die, their bodies lie in the tomb. The corpses, full of True Qi, start to deplete, and the essence of flesh and blood gradually seeps out, merging with their own imperial Dragon Qi and Inner Core, accumulating in the coffin over the years without dissipating. Over time, it forms a kind of crystal."
Sun Zhe asked, "And this crystal is the so-called Immortal Dew?"
