The path of martial arts cultivation is costly.
In the True Qi Realm, one needs to spend a large amount of Crimson Gold to purchase cultivation techniques and manuals, as well as pills for cultivation.
In the Spirit Sea Realm, the majority of expenses are even made with Crimson Gold!
After stepping into the Rotating Pill Realm and Heavenly Saint Realm, the costs are even more immense compared to the True Qi Realm and Spirit Sea Realm. Crimson Gold are no longer the regular expenses, and instead, one has to spend Spirit Stones directly.
After Ye Chen entered the Spirit Sea Realm, he entered an ancient tomb and didn't yet realize how enormous the expenses of cultivation could be.
However, through the words of the six powerhouses, Ye Chen already knew what possessing Spirit Stones meant.
