In frst 10 chapter... I can only say that it's your typical time rewind thing where MC is preventing all the bad things that happened in the future. He's OP and got the power stone which devours anything and the power of the things he devoured became his strength.
The FMC on the other hand is easy to fool, a bit on a bossy side because she's a leader. MC appears to be a beta on his past self but he is cunning now that he rewind to the past. He wants to protect the FMC for nothing but being simp, he don't want seggs bcs he see FMC as a "respectable" person. MC is a cuckold material.
FMC, even though she appears to be tough, she is a weakling and rape magnet. Most of manhuas have this thing. So fck it. She appears to be weak against muscle men so a little bit and this will go NTR.
For the plot, it's average but it's tolerable. It's adventure and action where they will hunt beasts and their goal is to become the top guild.
Most of the time, the conflict was all about making FMC a toy for the villain, raping her was their goal and it just pisses me off. I came for the romance or MC being OP but author always make them seems weaker and vulnerable.
The conflict was always seems to be too late to handle and MC is always one step behind even tho he return from the future. It's like the author is being sadistic.
There were too many borderline kinks here like rape, tentacles, old man and young, shota, ntr, and many more but the art sucks so it isn't really stimulating. Better luck next time. I say it's borderline bcs it's just a tease for the reader, for some reason, the female characters were always saved by the bell.
Tldr, it's quite good but MC is a shota and a cuckold material.
