Lu Chen wanted to refine the Fourth Tier Supreme Bloodline Evolution Liquid. Leaving aside the other supplementary materials, he still lacked one main ingredient beyond heavenly mandate rock, the Humanoid Divine Medicine, and the Enlightenment Coffin.
"I still need one more divine material as a main ingredient. Where can I find it?" He sank into thought, searching his memories for somewhere else on Big Dipper that might hold one.
According to the siblings Zi Yan and Zi Chuan, peerless divine substances such as Immortal Divine Medicine, heavenly mandate rock, the Heart of the Death Realm, falling star withered vine, and primordial life stone could all serve as main ingredients for refining the Supreme Bloodline Evolution Liquid. Each one represented another tier.
After pondering for a long time, Lu Chen thought of the Primordial Ancient Mine, a Life Forbidden Zone. Wasn't the primordial life stone within it precisely such a Divine Main Material?
But he could not possibly enter such a deadly forbidden land and retrieve the immortal ore. That would be nothing short of courting death.
"Primordial Imperial Clans like Divine Silkworm Ridge and Blood Phoenix Mountain have deep ties to the Primordial Ancient Mine. I wonder whether they have primordial life stone in their clans?"
Yet Lu Chen soon shook his head and dismissed the idea.
First of all, he had no friendship with those imperial clans. They might even want to snuff out a prodigy of the Human Race like him. Even if they possessed a priceless Immortal Treasure like primordial life stone, they would never trade it to him.
There might have been some possibility with the Divine Silkworm Princess, but in the original course of events, even the Fighting Saint Buddha had needed to venture into the Primordial Ancient Mine before finally obtaining primordial life stone
