The Legend of Enxue 

When his grandfather is suddenly brutally murdered by a member of the Demonic Martial Alliance, Fu Enxue vows that he will stop at nothing to avenge his death. To find the perpetrator, he infiltrates the alliance armed only with his wits and thirst for vengeance. There, he catches the attention of the demonic masters, as his overwhelming bloodlust makes him a prodigy in the demonic arts. But will this thirst for blood help him in his pursuit of revenge, or will that same power be his undoing? (Source: Tapas)
