Yang Kai was a trial disciple in High Heaven Pavilion and the ninth Young Master of the Yang Family which was of the Eight Great Families of Nine Continents.

One day, he stumbled upon a Black Book, which turned out to be the Great Demon God's legacy. This fixed his genetic defect and allowed him to finally practice Martial Arts.
