The Dark Identity in the Beijing Opera Cat
Sugar and Dark are twins (Dark is the elder brother, Sugar is the younger brother), and both are the sons of Xiu (White Sugar was originally named, Dark was originally named Xiaohei). The Xiu disappeared for hundreds of years, indicating that sugar was saved before the Xiu disappeared.
In order to grasp the powerful rhyme of sugar, Yan knocked it out, took it away, put it in an ice prison, and then combined it with chaos to create today's powerful chaos.
At this time, 500 years after some dark memories were cleared by chaos, Gircourt Lu (the patriarch) rescued the white sugar, poured all his poetic power into his seeds (practicing rosary) and gave them to Sanqing class to prevent tofu jiaozi from telling the truth about white sugar. The reason why sugar and darkness have no twelve lineages is because both sugar and darkness have cultivated lineages.
