Tribulation of the Azure Void

In the ancient calamity of Heaven's Mourning, the demon god Cangjie was sealed in the southern borderlands, and the five volumes of the Xuanhuang Strategy were divided between the righteous and the evil, sparking endless conflict for a thousand years. Shen Han, an orphan from Qingshi Village, bears the blood feud of his slaughtered family and joins the Yunque Sect. Though of mediocre talent, he hides the exotic treasure Black Stone Pearl within him. He rises to prominence in the Seven Meridians Martial Meet, but is suspected by the righteous path due to the entanglement of evil power. In a secret realm, he shares life-and-death experiences with Chu Wanqing, the young mistress of the Hehuan Pavilion, and also develops secret feelings for Su Yueying, a genius of the righteous path, despite their opposing stances. When a wrongful case suddenly arises, his beloved's soul is scattered, and Shen Han, wielding the Duan Cang Sword, falls into demonic ways, traversing both the righteous and evil realms. As the Cangjie seal breaks and all living beings are overthrown, faced with the ultimate choice of uniting the five strategies, will he choose the rebirth of his beloved or the world of heaven and earth? Heaven, earth, mystery, and yellow ultimately become ashes of tribulation. — Description from novelcodex.org
