Fang Zhixing blinked and said, "Is the blood of the Three-colored Snake the same as Yin Snake Blood?"
"Not at all!"
The old hunchback waved his hand, "To be precise, only the blood of a special type of Three-colored Snake can be called Yin Snake Blood!
This type of Three-colored Snake is pitch black with a white spot on its forehead, the area where black and white meet is translucent!"
Fang Zhixing was greatly surprised. This type of disproportionately black and white Three-colored Snake indeed seemed to symbolize the decline of the yang and the predominance of the yin.
The old hunchback continued, "This type of Three-colored Snake is quite rare, preferring shade over sunlight, and it is said that they die upon contact with sunlight, hence they dwell solely in extremely yin places throughout their lives."
Hearing this, Fang Zhixing immediately confirmed he had found the right person.
Spirit Deer Blood is yang-strengthening blood, while Yin Snake Blood is clearly its opposite.
