Background / History

Cao Xiyu is a transmigrator who spent two and a half years living publicly as the Ye family’s apparently ordinary son-in-law. He concealed both his extraordinary combat ability and his identity as a god within the Dream Entry Space, presenting himself as a man with zero innate soul power. 1

Under the identity of Brother Cao, he guided numerous young women through dream cultivation and created the Yin-Yang Reincarnation Technique. The technique’s public exposure through the Genius Ranking drew attention from Spirit Hall, the Seven Treasure Glazed Tile Sect, the Clear Sky Sect, and other factions seeking to identify or recruit him. 4 8 9

He disclosed his identity as Brother Cao and his role as the technique’s creator to Ye Lingling and Xiao Cui at the Ye Family Fortress. 9 His true strength became publicly undeniable when he intervened against the God Realm’s forces, killing Tang Chen with a flick and destroying ten divine officials in a single strike. 26

The Combat Power Ranking later identified Cao Xiyu as its first-place holder and bestowed on him the title Creator God. The Sky Screen subsequently broadcast his growth story and his life in the Dream Space to the entire continent. 53
