Those snake gallbladders improved his inner strength, along with the training, to almost Greatlike levels in a month. He went from well below Huo Du to slightly below Great in a month, which is at least 100-200% increase at least. How come he stopped improving at that ridiculous rate? You think the gallbladders only really help if your inner strength was mediocore in the first place, such as clearing your meridians and channels, or is it a rigid amount that just becomes insignificant after reaching a certain level?
Would they be useless to a Great who has already cleared his channels and thus have no noticeable benefits? If so, do you think Yang Guo would have reached Great level anyway, but he just got there much faster, but would have wound up on the same level? I assume the bladders strengthen your inner strength and clear your channels so it won't have much of an effect if someone like a Great takes it, unless he was sick or injured. I wonder if Hong Qi Gong would have been healed by these bladders. If so, it's kind of funny how it could have done what 9 Yin did by just eating bladders, and it would also grant 9 Yin level Martial arts. Rather broken.
