My Sister Stole My System after Rebirth and It Killed Her

I picked up a system with my sister.

The system said only one of us could bind to it, and the other could take twenty million dollars.

My sister shoved me aside and chose the money.

Ten years later, she squandered everything and ended up homeless.

Relying on the luck the system gave me, I excelled in my studies, climbed the career ladder, and reached the peak of my life.

Driven by jealousy, my sister stabbed me to death at my birthday party.

When I opened my eyes again, I was back to the day we found the system.
