Cultivation: I Can Reincarnate Into Various Worlds - Chapter 84. Eternal existence (seeking further reading)

So here's the pitch: I got reincarnated with Mangekyo Sharingan.Sounds overpowered, right? Instant win button?Except I can barely keep it active for thirty seconds without feeling like my brain's being microwaved. My chakra reserves are pathetic. My combat experience is zero. And the system that gave me these powers took one look at my situation and said “good luck” before fucking off into hibernation.Oh, and the Hero Killer—the guy who murders heroes for not being “worthy”—just decided my mom wasn't good enough. She'll never walk again.I know when he'll strike next. I know where. I've got exactly four weeks to train.Four weeks to go from “can't throw a punch without tripping” to “can survive a fight with a serial killer.”The smart move? Stay out of it. Let the pro heroes handle it.But I'm fifteen, angry, and apparently making life decisions with the wisdom of a shounen protagonist.At least I'm in General Studies. Low expectations.What does being a hero have to do with revenge anyway?

Three reincarnations. Fourth life.

She was chosen to grow up as the Child of Fate; but when the real Child of Fate appeared, she was sacrificed for that child.

In the second life, she was abused.

In her third life, she lived as a beggar.

“This country is not safe. Let’s defect!”

LeBlaine chooses to be re-born into a new family to defect. The family she chooses is…

… the family of the future biggest villains in the Kingdom.

“Let’s try to get along until the time of my exile!” is what she tried to do. But what happened was…?

“My daughter is the cutest IN THE WORLD!”

“Give me that building, I can use it as my sister’s bathroom.”

“Don’t worry, LeBlaine asked me not to hit you. Not to not kill you.”

“WHO, WHO MADE MY SISTER CRY?!”

“I betrayed the only man who stayed faithful to me, and died by the hand of the father I worshipped.”​Olivia Luceron was the perfect tool. For years, she acted as a spy within her own marriage, feeding her father secrets to dismantle her husband’s power. Her reward? A cold dungeon, a mutilated body, and a walk of shame through the empire’s streets.​Her husband, Duke Matthias, whom she treated with nothing but icy indifference, died protecting her. Her father, whom she gave her soul to, was the one who ordered her torture.​Now, Olivia has returned a year before her death.​The platinum hair she lost is back. The scars on her chest have vanished. And Matthias—the man who kissed her forehead in a dark cell before facing the executioner—is still alive.​She doesn't seek his forgiveness. She doesn't even seek his love. In this life, Olivia has only one goal: to use her position as the Duchess to systematically destroy the Locron family from within.​She will be the “Perfect Wife” this time—a mask of ice to hide a heart of fire.“Dear Father, you taught me how to be a monster. It’s only fair that I show you what I’ve learned.”
