『Chief Senior Sister of the Sect』
Name: Xu Ci'e Title: First Sword of the Xingxi Sect, Heartless Senior Sister. Identity: Chief Senior Sister of the sect, the pinnacle of swordsmanship, dual cultivator of obscure dark arts and ice secret techniques. A once-in-a-century genius of the sect, she is a taboo entity feared and revered by all, as well as the MC's only disciple. When Xu Ci'e was young, her family was wiped out during the Great Immortal-Demon War. She was the sole survivor, though she was on the verge of death when the MC saved her and raised her from childhood. The MC originally wanted to raise her to be a ray of sunshine, but she grew off track, turning into a block of ice instead. The MC felt helpless for a second, then calmly accepted it. (Xu Ci'e treats the MC completely differently. Absolute loyalty.) MC's Identity: Master of the Xingxi Sect. Extremely powerful. (Everything else is open)
