The Lost Heir's Revenge

Jovian's grandson, Dane Vaughn, survived an assassination by his uncles; his parents perished. Dane returns for revenge. He revives Jovian, who leaves for reinforcements. Dane declares war on Roxanne, Wallace, and Warren (Jovian's second wife and her sons), who poisoned Jovian and hired assassins for Dane's parents. Dane defeats evil forces with cultivation, then duels Nye the Ninth, his second uncle's murderer. Roxanne and her group receive just deserts.
