It was a good story at least from what I had in mind, until I made it too dark and it didn't turn out well.
I have learned from my mistakes and made major corrections to the story. Please give it a try and I hope it won't disappoint you.
To be honest I want to do a time skip, but reading previous comments people say that MC is getting Everything for granted and not even training for long, so I had decided that I would do a first and last long training arc as to help the readers understand that our MC actually puts in hardwork and doesn't Dilly dally all the time.
did you even read properly?? Use your brain as the system is still level 1 no techniques beyond level C have unlocked yet. Kage bunshin is a B level technique and he can learn it only after the system upgrades to level 2
