The Road to Redemption Begins in Demon Slayer

After transmigrating into the world of Demon Slayer, Ye Zi encounters a rather weak redemption System.

Because the System is so useless, Ye Zi is killed by Kokushibo during a redemption mission, then turned into a demon by Muzan on the brink of death.

Just when Ye Zi thinks there is no hope left, Muzan devours the Blue Spider Lily, and Ye Zi embarks on an even more extraordinary path.
