They Made Me Take the Fall. I Returned as the God of War, Tian Ce

Lin Feng transmigrates to an unfamiliar dynasty. His father has never cared for him, his mother died long ago, and his scumbag father and stepmother want him to take the blame for his elder brother.

You want me to take the blame? I don't mind. Just don't mind when I wipe out your whole clan, okay?

Taking the blame once makes Lin Feng the Mad Dragon of the northern frontier. The Xiongnu fear him, the emperor dreads him, and even the princesses fight to marry him...
