Sword Saint, Reborn a Coward

Synopsis

They called me the Sword Saint, the one blade that ended the Demon Cult and the one man every sect wanted dead for it. They poisoned my wine at my own victory feast. I woke thirty years in the past, in the soft body of Mun Garam, the cowardly third son everyone forgot. The good news: I remember every technique I'll ever learn. The bad news: my legendary sword woke up too, and it has no idea who I am, and thinks I'm pathetic.
