Should these Inner Strength proficiency points be applied to the 'Breath Control Law' or the 'Yijin Bone Forging Chapter'?
Both choices have their pros and cons. Considering the requirements for cultivating the advanced Inner Strength technique 'Hun Yuan Gong', both of these Inner Strength techniques need to continue to be upgraded.
If considering the attributes of these Inner Strength techniques alone, the 'Yijin Bone Forging Chapter' would certainly be the preferred option.
Because, for every level raised in the 'Yijin Bone Forging Chapter', the attributes increased are more than those from improving the 'Breath Control Law' by four levels!
Moreover, due to the difference in the level of cultivation of these two Inner Strength techniques, if these 7,500 proficiency points are used in the 'Yijin Bone Forging Chapter', it could effortlessly be leveled up by two or three levels.
