Yang Kai was just a Trial Disciple of High Heaven Pavilion. Unable to cultivate, his status was that of only a servant within the Sect until he met with a fortuitous encounter, changing his destiny. This chance induced him to move towards the peak of Martial Arts, which seemed to be at an eternal distance from mere mortals.
He looked frail and weak during his teenage years at High Heaven Pavilion. After he started cultivating, his temperament and appearance became more calm and composed.
Neither arrogant nor servile, Yang Kai has a calm, shrewd, and confident personality. He is notable for his ruthlessness toward his enemies in stark contrast to his loving, caring and generous affection for his allies, family, and friends.
Yang Kai was a Trial Disciple in High Heaven Pavilion and the ninth Young Master of the Yang Family, one of the Eight Great Families of the Great Han Dynasty. One day, he fortuitously obtained a Black Book, which turned out to contain the legacy of the Great Demon God. This fixed his genetic defect and allowed him to finally practice Martial Arts, where he subsequently excelled.
