The other aspects of the Sacred Beast Pill formula were already figured out by him during the return journey. For him, at present, whether it is the beast blood, beast bone, or the quasi-third tier spirit medicine, none is difficult.
Only the main medicine, the innate origin essence blood.
The so-called innate origin is an accompaniment within the womb, but once born, this innate origin will be absorbed and refined little by little.
And the essence blood needed for the Sacred Beast Pill must be extracted from the demon core.
This is even more challenging.
After all, any demon beast that has condensed a demon core is already a second-tier demon beast, where would there still be any innate origin left?
So, ninety-nine percent of the demon beasts in this world are not suitable.
However, the Sacred Beast Pill formula that the Liu Family accidentally acquired records a few special demon beasts at the second tier that still contain innate origin essence blood.
