Golden Core, contains the word "gold" within it.
What is gold?
Condensing Essence, Qi, and Spirit, and tempering them with thunder and fire, one can achieve gold!
To achieve the Golden Core, a cultivator must face a catastrophe of thunder and fire!
This fire is the Heart Fire, which ignites spontaneously from within the cultivator. If one cannot withstand it, all their mana will turn to ashes, their soul dispersed.
The thunder is Celestial Thunder, striking from a clear sky, with the power to subdue all. If one cannot withstand it, the physical body will be reduced to char, and all life will be extinguished.
This is the tribulation of the Golden Core!
Incredibly difficult!
Ordinary Spiritual Artifacts and Dharma Seals will be shattered to dust by Heart Fire and Celestial Thunder in an instant, utterly unable to resist.
Out of ten cultivators attempting a realm-breaking, nine usually perish tragically, leaving only one to achieve the Golden Core.
