Yi Pin Bu Yi

A modern engineer named Xu Mu wakes in the body of a street-corner layabout, in a dynasty coming apart at the seams. Everyone around him assumes he's the same worthless drifter he's always been, and the offers of a wife come as jokes at his expense. Then a daughter of wealth, fleeing the collapse with nothing left, crosses his path. Blade, bow and horse are all he has, and he means to keep the people under his roof alive.
