Review Detail of Blood_Empress in System vs Rebirth

After she died and reincarnated she can never come back to original world she can only reincarnate in parallel world bcz she is already dead in original world

Yep, that's how reincarnation normally works since time always goes forwards, never backwards. So if someone reincarnate to the past then it's not really the past but a parallel world which is in the past. Plus, you can also consider reincarnation as their fate since it never happens randomly. Theres always a reason behind their reincarnation. So it's not really a stealing of fate since it was her fate in the first place. But it could also be that fate isn't really real and just a concept created by humans. If so, then there's nothing to worry about about and she's just using the knowledge she already had. No one can blame anyone for utilizing the knowledge a person holds for their own benefit.

Systems are as bad as regressions if not worse. Systems simply a nuanced reality and all you have to do is grind like a video game to get to a position of someone that worked for years with the barriers of nuance. Let me elaborate with a scenario. Let’s say a system user decides to become smart. They invest in intelligence or do things to grind with an overly simplified and clear understanding of their “intelligence” if you can say that anymore. And you will see the “intelligence” of others without taking into account of the various types of intelligence such as social, mathematical, theoretical, strategic, or all kind of intelligence. Boosted intellectual will either be a scam because it makes you believe your overall intelligence on everything will be better. Alternatively, it becomes a pure cheat as every form of intelligence rises to unnatural extents and arguably even worse than knowing the future.
