The Core Formation notes said that the essence of a cultivator forming a core ultimately lay in taking the cultivator's essence,
and original Qi, condensing them with spiritual will, and uniting the Essence, Qi, and Spirit Three Flowers.
They would form a "Dao Embryo" that brought together everything the cultivator needed.
This Dao Embryo was the Golden Core.
But saying it was easy; doing it was anything but simple.
An ordinary Foundation Establishment Realm cultivator had a lifespan of a mere two or three hundred years. Cultivating essence, Qi, and spirit to a level sufficient to condense a Dao Embryo was as difficult as climbing to heaven.
Not to mention that as their lifespan ebbed away, their essence, Qi, and spirit would steadily weaken, leaving them even less time to achieve Core Formation.
That was why they needed the assistance of external aids such as spiritual objects of heaven and earth, pills, and formations.
As the Essence, Qi, and Spirit Three Flowers gathered, whatever was lacking had to be supplemented.
Essence and Qi were intimately tied to a cultivator's vitality and lifespan. Precisely for this reason, among cultivators who met the requirements for core formation, younger ones had a slightly higher chance of success.
Spiritual will was related to a cultivator's cultivation realm. Beyond that, the cultivation world also had cultivation methods specifically for training Divine Sense, but they were exceedingly rare.
However, Core Condensation differed from Foundation Establishment. Failure did not mean the chances of future success would decrease.
Since the heart of core formation lay in essence, Qi, and spirit, so long as these three flowers remained undamaged, each attempt was the same for a cultivator, no matter how many they made.
Of course, if they failed too many times, they would inevitably become burdened by frustration and
