My younger sister and I were the most gifted twin snakes of our generation. To help us attain immortality sooner, the elders found two dying women for us to possess. Because my talent was greater, I was assigned to the legitimate daughter of the Minister of Revenue and sent into the imperial harem to absorb the emperor's dragon aura. My sister possessed a female physician and married a general who had no interest in women. In three years of marriage, they not only never shared a bed, they barely even saw each other. Unable to absorb any yang energy, my sister used a visit to me at the palace to seduce the emperor. Together, they plotted the general's death and killed me as well. When I opened my eyes again, I was back on the day we possessed our hosts. Faced with my sister's pestering, I gave up the minister's daughter and chose the physician instead. Serving an emperor is like living with a tiger. The people's hearts are worth more than dragon aura.
