Concept Core

Concept Core was a rare realm. Meeting an expert of the Core realm was harder than reaching the sky. Out of billions of cultivators, only one would reach this realm. To step into this realm, one would need to fuse their 9 pillars with a treasure. This treasure could be an elemental leaf, or other certain specific treasures dealing with a concept. The concept core formed will be a result of the treasures used for its formation.

A cultivator would then have to understand the concept of their core. This required a person to grasp their concept and understand it's essence. The cultivator would then have to be able to use the power of its concept without any assistance from their cultivation base. They would have to merge their understanding of the concept with their cultivation. Lastly, the cultivator would then have to be able to use the concept and their cultivation base at the same time with moderate efficiency.

As a final step, a cultivator could mark their pillars with runes of their concept. This would allow for less energy usage when using their powers along with the cultivator's speed increasing. This step usually would only be done by those with powerful backgrounds as runes were extremely rare and hard to mark.

After reaching the concept core, a cultivator would be able to see extra colors and live for hundreds of years. A cultivator could witness the rise and fall of mortal dynasties. Just by relying on their concepts alone, a cultivator could battle against those of the foundation establishment rank.
