I understand that because he has a dark golden ball his spiritual reading potential is of the highest caliber. But let's say someone else started off with liquid instead of a dark golden ball and later on he became War God level physical strength/speed/reaction, will this make his spiritual reading also be at High War God level ? Or will it be weaker. Basically if you're born with less potential spiritual ability but reach high level physical capabilities will your spiritual powers automatically catch up ? Cos that would suck and make Feng's potential pointless at the highest level.
Also the Seven Ray Knife, it's a knife handling technique, right ?
