Solo Leveling: ReNix

Floating at an endless void in the valley of the dead, tears slowly floating away from her face.

She had sacrificed her life for the life of millions of other in her country, it was her choice.

A life with the man she both hated and loved at the same time, so that others could live.

It was her choice, it was her that had made that choice, but she couldn't help regret her choice.

Until, a chance appeared before her. A chance to rewrite the fate she couldn't have changed, all within a single word.

"Would you take the chance?"

A regressor that had the chance to become a player and change the fate of the world vs A player that had the chance to regress to change the fate of the world.
To which will be the true one to take the spotlight of the world's center focus, it's "Stellar Paralax"?

"Regressor, gamer, what else? Ah, of course... I'm a f*cking billionare"

At first, I wanted a rewrite of my SLJTEO FF, but then I got this instead. I don't know how to express how much I planned for this that I even forgot about the origin book, LoL. Anyways, go straight dive in!
Ah, also, the image used for the poster isn't mine, I can't site the full name of the person who posted it, so I'll say that it came from the pinterest. I'm sorry that I can't fully cite the name of the person.
