In Lin'an, Jiangnan, Su Wanqing, a simple and kind-hearted daughter from a wealthy family, fell in love with Lin Jingyuan, a poor scholar. On the eve of spring, in order to help her sweetheart calm down, Su Wanqing gave Lin Jingyuan the ancestral sachet left by her mother. What she didn't know was that the sachet contained no ordinary spices, but ambergris, a rare treasure that was said to be able to bring the dead back to life.
