But back then, Rhein told him that anything related to breaking through the 17th level of Spiritual Energy and condensing the Primordial Law was considered the highest level of Black Fog taboos.
Only upon returning to Saint Longde could this be spoken of.
Of course, this was part of the Fire Holder's system, which Rod might not be able to use.
But the Book of Knowledge, perhaps it could serve as a reference, to recall something.
"Master, I am sure these memories are erased, not in my Soul Fragments. As long as you give me some clues, I can remember them."
In the Dream Realm, the Book of Knowledge said excitedly.
It vaguely had a premonition that the master would gain a significant advancement here.
Soon, Rod followed Rhein to the bottommost level of the Holy Fire Sacrificial Ground.
