Reincarnated as the Descendant of a Fallen Noble

The strongest knight of the Pavion Empire, Barrach Daphne, is reborn. But this time, he's reborn into the body of a descendant of a fallen noble. "Why is this guy in such a state? And why is the family in such a mess again?" From top to bottom, he had to revitalize the Daphne family, which had nothing left. "Oh god, why are you doing this to me?" ...It seems like it's going to be damn hard.
