The Ancestral Art of Accepting Yin

Chen Fengcai has three ancestral items. One is Nayin Pavilion, a store where he can run a household and make money; the other is a double-jointed whip, a magic weapon that can connect yin and yang; and the last one is Nayin Technique, which can suppress yin evil, transform evil spirits, and pray for good luck. This is the second year that he has taken over Nayin Pavilion. Business is particularly good. Yin objects appear one after another, as if someone is rushing to deliver them. While he is making a lot of money, he can't help but feel a little vigilant.
