The World Is a Bit Chaotic

Two little sisters grew up together. One has outstanding literary talent, superb medical skills, and is plagued by diseases, elegant but not quiet; the other has strong martial arts, great dancing skills, and looks like a fairy, but is not enthusiastic. One is a princess, but lives among the people; the other is the jewel in the eye of the Murong family, one of the four major families. One was adopted by an adoptive father and was loved very much; the other was a biological father, but he betrayed his biological daughter. One's family was ruined and he went out to find a wife with his wet nurse, while the other was tricked and went out to get married. Accidentally, the two walked together again. Another accident, the two exchanged identities. One married into the Shangguan family, one of the four major families, and the other found his "biological father" and married into the palace. One was forced step by step to become a martial arts supreme, and the other slowly became the master of the harem.
