Yun Yuan, an 18-year-old modern girl, accidentally enters the Youlong Realm after the college entrance exams and becomes a direct disciple of the Third Peak of the Tiance Sect. Possessing supreme Gold Spiritual Roots and innate sword bones with peerless talent, she is a climber to the top of the myriads of heavenly ladders, a dual-sword sword cultivator, and a top artifact-refining genius. Clear-minded, optimistic, and highly perceptive with a natural modern sense of sarcasm, she initially lacks practical combat experience and is soft-hearted. After experiencing the bloodshed and vicissitudes of the immortal cultivation world, she sheds her greenness, becomes decisive and ruthless, takes on heavy responsibilities, and grows into the core of the team. Arrayed in red with a cinnabar mark, dual swords by her side, and wielding the Vermilion Bird fire, she carries a dashing and uninhibited demeanor, step by step shouldering the grand mission of the five realms.
