The Spirit Stones were purely for decoration. Considering Tu Xiao'an's current Level and Cultivation, the three thousand Spirit Stones he'd gotten from the vice-dean were of no use to him anymore.
Tu Xiao'an had simply grown too quickly.
Using the Golden Core of a Rank Three Demon Spirit, however, was a different matter. Tu Xiao'an knew that while his corpse wasn't rotten, its life force was long gone. The blood within had coagulated and ceased to flow.
His goal this time wasn't just to take a drop of blood, but Essence Blood—the very essence of life.
Extracting Essence Blood from a corpse was, frankly, asking for the impossible.
So, he extravagantly used a Demon Spirit's Golden Core to forcibly liquefy the blood in the corpse and get it flowing again.
The Golden Core of an enlightened Demon Spirit had many uses. After all, it normally took an animal at least several hundred years of step-by-step Cultivation to become a spirit, then a Demon.
