Heretical Golden Cores can be continuously strengthened.
However, the strengthening of a Heretical Golden Core is not something that can simply be done at will; concocting a Heretical Golden Core requires various herbs.
And for the Second Layer of the Heretical Golden Core, various materials are needed.
But when it comes to the Third Layer of the Heretical Golden Core, assorted auxiliary materials are not sufficient—it requires a Spirit Pill.
The so-called Spirit Pill is not the miraculous panacea people often talk about, but rather a kind of spirituality, a sort of instinctive spirit.
This spirit is different from the legendary Sword Spirit, which even possesses its own intelligence.
But according to Master Zhang's alchemy theories and records, although the Spirit Pill has some life essence, it does not possess intelligence; it's merely a pure instinct to seek benefits and avoid harm.
