Bai Xuan

Biodata

Power Progression

Bai Xuan's rank is distinct from his individual attribute ratings; his attributes improve before several of his rank promotions 4 20.

Background and history

Bai Xuan and his older sister Bai Yu are not related by blood; they grew up together in an orphanage. At eighteen, he awakens the World Book. Increasingly frequent Anomalous Calamities—and the danger of Bai Yu's public-security work—drive him to use it to become stronger 1 120.

His first summoned Legend, the succubus Holy Knight Xilin, defeats a ghoul while Bai Xuan watches from a distance. He subsequently creates more Legends, including the Ruby Dragon Marée Alaira and the fairy Luo Miaoyin. He initially hides both his companions and his role as the man in the Slime Mask from Bai Yu 2 4 18 71 154 158.

As his group grows, Bai Xuan takes on higher-ranked calamities and becomes involved in conflicts concerning the Evil Organization, the World Tree, and the Scar of Heaven. Bai Yu eventually discovers his masked identity 147 158 161 182.

Personality

Bai Xuan is protective of Bai Yu, but his secrecy can override her ability to make informed choices: he injects her with a Gene Enhancer while she sleeps and later gives her the Elastic Body profile without telling her. He also prioritizes her safety when advising her about whom to trust 19 31 161.

He often approaches stronger opponents as problems to solve rather than fights to win by force. His poison trap against Xu Yan and repeated attempts against the Purging Knight show his willingness to observe, adapt, and endure setbacks 32 208. Around his companions and classmates, he frequently jokes and teases, though he remains guarded when he suspects someone has hidden motives 30 38 107.
