These are quite harsh requirements, as I clearly know that the standard of this Palace is quite high and I likely have to perform the 16 moves of Body Cleansing Technique and reach the 10th Accomplishment in Secrete Method.
I am saying that because of all of the Inheritance obtained through this ruin had been very high level and the inheritance I've obtained is likely level above that and only use this inheritance when I met all of its condition, otherwise, I will die horribly.
High-level Inheritances have lots of conditions and one has to meet all of the conditions before one could even think about fusing with that inheritance if the conditions are not met, one has to suffer very grave consequences like never able to practice magic again or death.
