12 meridians true Qi explanation?
So I am confused about what 12 meridians true qi actualy means. Jiang Chen mentions that this worlds perception of what it is, is wrong, but I didnt understand what he said it was. Now I am at ch 160 or so and he is preparing to go for spirit sea but it hasnt mentioned him getting the 12th meridian, so whats up? I doubt in a wuxia novel the MC wouldnt have the best of teh best base cultivation so I am assuming i just understood something wrong. Can someone clear it up for me?
