Rich Daughter Reincarnates as Her Eighteen-Year-Old Self to Rescue Her Younger Brothers! - Chapter 259 - : Possessiveness

Roy’s life was nothing special. The only thing commendable was the last few moments when he saved a mother and her child from a drunk driver.
…
It’s really an egg! Damn it, what kind of monster have I become? Did I fall into Hell instead of making it to Heaven??
Join Roy as he ventures through various worlds with the Custom Made Demon King System—a system that allows Roy to draw anything he can imagine and create it through exchanging souls!

​The world, Earth, was devastated by the Great Incursion, an apocalyptic invasion by dimension-hopping monsters. Humanity's only hope now lies in Galaxy Fall, a newly accessible parallel world where they can gain strength through a System of quests and missions.​Five hours after the Invasion, the betrayed survivor Mirabella is mysteriously reborn and gains a unique power: the [Master Account System].Her initial skill is the deceptively simple but devastating 'Multiplier x100', which applies a 100 times buff to all her offensive capabilities, including physical attacks, spirit energy skills, and damage-over-time effects.​Mirabella must now transform from a silent survivor into the world's most feared warrior, who was only scared of one thing, which is?“I Hope I don't run out of opponents in Both worlds.”

She was a medical expert, talented and beautiful. She was reborn as his little wife. Her in-laws did not like her, her husband did not love her, and she was as timid as a mouse. She was weak and easy to bully.

The Third Dimension is collapsing. The Fourth Dimension is descending.

First it seemed that only technology would evolve, but who knew the world itself could too? It wasn’t as simple as climate change or tectonic movement. No, the fundamental laws of physics that governed everything were changing.

Leonel was fairly lucky. His family was decently well off, his father loved him enough to brew vomit inducing nutrient rich smoothies every morning, and this was both the day of the National Championship and his 521st confession to his dream girl, Aina. As his father always said, nothing was more important than respect and persistence.

Unfortunately, everything changed that night. At the after party of ages, the world reached a saturation point and an apocalypse descended.

Abilities awakened. Sub-Dimensional Zones opened. Invalids rampaged through the Earth like a virus…

Those who could evolve would have a slim chance for survival. Those who couldn’t would die.

This novel will be a unique spin on the dungeon/system genre. Dungeons won’t be dungeons and the system won’t be a system… Take a look to find out what I maen :)
