The furnace purgatory stone was one of the treasures that could aid in performing False Dao Integration Advancement, as recorded in Xiong Ziqi's secret art.
The other two were the heaven-covering fruit and the three-colored qianji flower.
Any one of the three would suffice, but the furnace purgatory stone was the least effective.
Unfortunately, according to Zhao Yingnan's message, neither the heaven-covering fruit nor the three-colored qianji flower existed in this world, leaving him no choice but to use this stone.
Still, even if Xiong Ziqi's secret method allowed him to advance to Dao Integration without attaining greater mastery of a Dao art, he would first have to reach void refinement perfection. What he needed to do now was seize every moment to cultivate.
At the thought of cultivation, Chen Lin could not help frowning.
Since arriving in this world, he had broken through to the void refinement mid-stage and then to late void refinement. His progress had already far outstripped the normal pace. Although this world was unusual and the Divine Pillar boosted cultivation, advancing so quickly would still leave hidden problems.
