I don’t particularly like have another characters, other than the MC, with a so called golden finger (regression, transmigration,etc..). It takes away from the MC aura, ruining the story for me. There has yet to be a novel that did that which I haven’t dropped soon after. Hope that this is the one.
Nitrigo:No scratch that. There was one novel that I read till the end; but it was different in its utilization. Reincarnation, regression, and the like were backgrounds(similar to being a scion of a big clan) and not golden fingers. So they didn’t really provide cheats anywhere close to the system the MC had.
