Demon Slayer: Enichi Tsukuni Returns from Hell

[Yuanyi's personal rebirth + no system + no cruel persecution + making up for regrets] [Facing the beginning without misfortune] [For some reasons, Yuanyi knew part of the plot] When the twilight swordsman passed away due to old age, the end of death did not come. Although I have never felt that I am any special being or have any extraordinary talents... However, if fate insists on dragging those who have tried their best into the deep darkness—— The guy named Yuanyi still seems to want to do something. At least at this moment, he had something he wanted to ask when facing Muzan who was on Yuntori Mountain. (I am not a newbie, I have written a book about parallel worlds.) (In the author's eyes, Yuanyi is invincible, so apart from the miserable start, there will be no ghosts that can escape from him.) (The pace in the early stage is slow, focusing on making up for regrets. If you want to see Yuanyi show his magical power, you probably have to wait until the plot of Yi Wo Zuo.)
