After killing the Gold-Eating Beast, Zhou Yang did not hurry back to his Huohua Mountain cave residence. Instead, he detoured to the site of that giant spirit stone mine.
By this time, after the Zhou and Guo clans' continuous excavation, nearly half the spirit stones stored within the vein had been mined. The number of top-grade Spirit Stones recovered had reached seven, all of which had fallen into Zhou Yang's hands.
Zhou Yang now possessed ten top-grade Spirit Stones, making him enormously wealthy.
As for Spirit Marrow Stones, which could rapidly restore a cultivator's magic power, there were even more of them—nearly seven hundred in total.
Zhou Yang had not come to the mine this time to collect newly excavated ore, but to visit his spirit pet, the Golden Winged Thunder Eagle, which he had stationed here to guard the mine.
Several centuries had passed, and this spirit pet, which had evolved after absorbing the Silver Winged Thunder Roc's blood essence, had already advanced to Tier 5 High-grade.
At this level of cultivation, given the Golden Winged Thunder Eagle's innate bloodline, it would be extremely difficult for it to advance any further.
But nothing was absolute. Demon beasts' advancement could be difficult, yet it could also be simple.
As long as they obtained and devoured the demon cores of high-level demon beasts with bloodlines close to their own, or swallowed large amounts of true spirit blood essence compatible with their bloodlines, they would have a great chance of breaking their bloodline shackles and advancing successfully.
Zhou Yang actually already had a plan for the Golden Winged Thunder Eagle's opportunity to advance to the sixth tier. He merely needed to wait for the right moment to put it into action.
