Regression of Guardian Princess

There stood a gorgeous beauty was kneeling on the ground about to be executed in front of the public of kingdom.
She was the greatest business woman in the whole history of kingdom, she was called "Angel guardian of Poor" because of her helping nature. But this all good situation of her started to crumble when she got married to prince, she gave her all in this married life to make her husband happy. Still she was targeted by the other people who don't want this marriage started to flourish. They staged many crimes in her name, and even her husband didn't believe in her innocence. Her reputation crumbled to dust.
And all these things together bring the situation to what it is now.
As she was about to be executed.
She thought that it was right thing to let his heart out.
"I, Genesis Hale question the guardian dragon who gave the power to the royal family. They are not worthy of this power anymore, they couldn't defend the innocent who is receiving injustice. Eyes of Royal family can not differentiate between good and evil. This family need to be destroyed or need to taught how to be justice provider, good ruler and many more things."As she just uttered this words, with the swing of the sword, her head got separated from body.
But, this wasn't the end for her, as she appeared in a black place, a looming presence stood in front of her. It was the golden dragon mentioned in many legends related to royal family, but he was covered in the black wounds all over the body.
"You are the hope of world, embrace my power and guide the people, and lead to prosper, guide the misguided the people, guide the royal family. Live and take benefit of this second opportunity."
Before She could understand anything, she appeared in her body when she was a child of 17 year old.
