The reason Ye Han thought this pitch-black crystal stone was rather special was that it might just be what he was looking for...
Though it looked utterly unremarkable and gave off no aura whatsoever, that very absence of an aura made Ye Han realize it was no ordinary object. A cultivator would never put something completely worthless into his Storage Bag...
Besides, this crystal stone had been placed inside a Gold Box and sealed under layer upon layer of restrictions. The fact that it still gave off no aura after the box was opened was strange enough in itself.
The crystal stone was not the true object being protected; what truly needed protection was the thing sealed inside it. With Ye Han's formidable cultivation and wealth of experience in examining and identifying things, he determined that this pitch-black crystal stone was not actually a crystal stone at all, but an even more powerful seal. What lay inside was a treasure that might allow the Heaven-Devouring Cauldron to produce a dark-attribute Spirit Root Fruit...
Could it be the legendary darkness spirit liquid?
Ye Han discovered wisps of liquid sealed inside. It was very likely the rumored darkness spirit liquid. If so, it was a treasure that would very likely allow the Heaven-Devouring Cauldron to produce a dark-attribute spirit root.
Although developing a dark-attribute spirit root when Ye Han's cultivation had already reached such lofty heights would make his immortal ascension more difficult...
It would also make him more perfect after his immortal ascension. When that time came, his true immortal cultivation would immediately surpass that of ordinary cultivators who had just advanced to become true immortals...
Of course, the first stroke of the character had yet to be written; he could not say he would definitely become a true immortal. But
