Si Wuli, the Ninth Prince, discovered a strange medicine that could cure his mother's illness in the palace library, so he sneaked into the Netherworld Valley alone. Then he fell in love with Song Qinglou, the owner of the valley. During an all-out battle, Song Qinglou discovered that Si Wuli's purpose was to get back the Dripping Water Guanyin and help the court eliminate the evil cult Nether Valley. Song was immediately furious and vowed to take revenge. Eight years later, Song failed to assassinate the Queen Mother and was left in the palace. All this was just the beginning of the game.
