I forgot the backstory of this manhwa, it's so long.
The mc was a master who died and reincarnated, right? But did he go back in time to his old body, or did he take over someone else's body? Or was he reborn as a baby?
If he took over someone else's body, did he keep their memories? And what were his thoughts on this body's grudges and family, etc.? I assume that he was like "don't worry, I'll avenge all these injustices you went through" like they usually do in this type of manhwa?
