In the ancient calamity known as Heaven's Sorrow, the Demon God Cangjie was sealed in the southern frontier. The five volumes of The Xuanhuang Strategy were divided between the righteous and the wicked, and their conflict raged on for a thousand years.
Shen Han, an orphan from Qingshi Village who carried the blood feud of his murdered family, joined the Yunque Sect. Though his talents were ordinary, he concealed a rare treasure, a black stone bead. He distinguished himself at the Seven Peaks Martial Arts Tournament, but the righteous suspected him because of the evil power that clung to him. In a secret realm, he and Chu Wanqing, the young mistress of the Hehuan Pavilion, risked their lives for each other. Meanwhile, his views clashed with those of Su Yueying, a genius of the righteous path, and feelings quietly blossomed between them.
A wrongful case erupted, and his beloved's soul scattered to the winds for his sake. Wielding the Broken Sky Sword, Shen Han fell into darkness and traversed both the righteous and wicked worlds. When Cangjie broke free of his seal and all living beings faced ruin, he stood before the ultimate choice after the five strategies were united: should he choose the rebirth of his beloved, or the world between Heaven and Earth?
Heaven, Earth, and the Yellow Realm all became ashes of calamity.
