Golden Finger Artifact: [Mirror of Destiny]. An ancient artifact can connect four souls together under certain circumstances (such as four people dying at the same time or harboring great resentment). It can reflect everyone's "original" tragic fate and give them a chance to be reborn. They can communicate mentally, make plans, and even share limited power at critical moments in the mirror space.
World view: A dynasty called "Daxia" has three pillars: the court, the rivers and lakes, and the aristocratic family, with undercurrents surging. There are slightly fantasy elements, such as internal power, poison, and "superpowers" possessed by a few people.
