"I've heard that it can be refined…" said Little Tree when it saw Di Jiu's unfriendly expression. It stopped talking for a bit before it said weakly, "You can also use Blood Essence…"
Di Jiu perked up. That was a good idea. He sprayed a jet of Blood Essence onto the gray stone without hesitation. However, the stone did not react, even though they waited for a long time.
Di Jiu picked up the stone disappointedly. As his cultivation level increased, he believed that hanging this stone around his neck would not be beneficial.
Whenever he used his Spiritual Force to come into contact with the stone, he could sense a colossal aura within the stone. This aura seemed to be a product of a fusion between a form of Origin and a type of Law. If he met any experts in the future and they scanned him with their Spiritual Force, all his secrets would be exposed.
