Dual Polarity Extreme Yin Physique was a very peculiar one, and Wu Long only read about it and heard of women who possessed it. It was in many texts called the "Hidden Yin Physique" as the possessor of this physique would not have any indications of an Extreme Yin physique in a non-active state.
It was, like the Frozen Soul Extreme Yin Physique he saw earlier, a physique that apart from other things affected one's personality. Its name stemmed from Yin and Yang, as Yin and Yang meant not only feminine and masculine, but also could mean light and dark. Dual Polarity Extreme Yin Physique possessors hid themselves in the Yin using the Yang of their personality, which meant that they were concealed in the dark while hiding behind the light. The Shen Min that Wu Long knew before was a fake persona donned by the real her, as she pushed all the light side of her personality to the outside, and hid her real intentions and consiousness inside, erasing a part of memories in the outer persona.
