The heroine Wuming was originally a young monk with mediocre qualifications, but she accidentally entered the ruthless path, which is the most difficult to graduate in the world of immortality. She is not obsessed with love, nor is she trapped by fame and fortune. Through repeated experiences and choices, she gradually understands that "ruthlessness" does not mean indifference, but fairness, self-examination and keeping one's heart. Faced with prejudice, conflict, and the test of good and evil, she chose not to go against her original intention or selfishness, and used her actions to promote changes in the spiritual world.
