Zhang Jingyan, a Daoist tribulation-bearer who witnessed Emperor Zhuanxu sever the link between Heaven and Earth, has kept his lonely vigil for ten thousand years, upholding his vow: “Retreat in times of peace; wield the sword in times of chaos.” In 2035, he is awakened by a flood of foul, malevolent thoughts beneath the snowy Kunlun Mountains. He descends into the mortal world and meets Jiangnan. Before the weathered stele of an ancient temple, Su Wanqing, a photographer who records what has vanished, glimpses through her spiritual sight the clear, glasslike Daoist aura flowing around him. It is the light of truth she has sought for so long. Her purity and resilience become the bridge connecting him to this unfamiliar era.
