In the past, Lu Qing was reluctant to use top-grade Spiritual Stones for cultivation, but trying it this time, he was astonished.
Unfortunately, he didn't have many top-grade Spiritual Stones in his possession.
Apart from obtaining a small amount from those Primordial Spirit Realm cultivators he slew, the majority came from the Gongsu Family's treasure vault in Zhou Tian City, totaling one thousand top-grade Spiritual Stones.
But he wasn't sure if these more than a thousand stones would be enough to advance his Cultivation to the Primordial Spirit Eighth Tribulation.
"We're still poor..." Lu Qing couldn't help but sigh.
With his current Mana quality, the effect of Middle Grade Spirit Stones was minimal.
Only top-grade Spirit Stones could quickly enhance his Cultivation.
But top-grade Spirit Stones were rare, only some top sects in the Heavenly Origin Great World had accumulated them.
Obtaining them was quite difficult for Lu Qing.
