The balance of essence, qi, and spirit is the most fundamental foundation for condensing the embryonic form of the Golden Core, making them complement each other and merge into one. If one cannot achieve this, then even if they manage to momentarily consolidate the embryonic form of the Golden Core with immense power, it cannot remain stable. As the Golden Core becomes more refined, the likelihood of it exploding increases.
The practice skills these people switched to for Golden Core formation were modified by Pei Xuanjing; they were significantly simplified, with no other distinguishing features, used solely to harmonize the balance between essence, qi, and spirit, and fuse them into one.
But why, after practicing according to the description of the skill, do these people still find themselves unable to truly balance essence, qi, and spirit?
It is because they ignored their own characteristics, leading to this result.
