It’s the age of superhumans!Genetic modifications, Cybernetic enhancements, magic enchantments- the choice is yours! For the right price, you can rise above the masses and gain power only ever seen in myths!For the right price!No matter how far humanity advances, power will always fall in the hands of the wealthy few. It was a truth Dante learned at a very young age and with it came a burning hatred for those who look down on everyone from their ivory towers.The flames grew stronger once he found himself faced with the cruelty of those who rule from above. He swore revenge on each and every one of them, but true power couldn’t be fought with hatred alone.In his search for a weapon that could help him take his revenge, Dante crosses paths with a certain Artifact, his fate taking a turn he could never have anticipated.

Lying on the hospital bed, Yu Bing, who was severely ill to the point she could not open her eyes, could do nothing but wait for death. Because of her frail body, her parents had disliked her since she was born. And because of what happened in the countryside, her elder sister hated her for a lifetime. Her second sister, Yu Yan, who had been sent away as a child, also hated her for some bizarre reason. All kinds of framing and setup were used on her, and they even stole her fiance from her…

As she didn’t get enough love and care since she was young, she regarded Yu Yan’s false kindness to be real and treated her sincerely, only to have the former trample all over her reputation. For the sake of getting a smile from her parents and some false praise, she lived frugally until she almost died. Looking back on her life, Yu Bing felt it was absurd, and endless resentment festered in her heart. She had never done anything to anyone, so why? Why did those relatives and close family members treat her this way? Since they didn’t want her, well, then she wouldn’t treat them like family anymore.

If there was a next life, she didn’t want to be the Yu family’s daughter! “She’s my sister, so how can I not love her? But the dead have to make way for the living. It’s rare that there’s such a happy event in our family. We can’t let her bad luck taint this home!” Familiar words rang in her ears. Yu Bing opened her eyes with difficulty, and found that she had been reborn back to when she was younger! She had been reborn to the eve she had been sent to the countryside. Her family was arguing about who to send to the countryside in response to the call of the country.

Her elder sister had gotten married in a hurry as she didn’t want to be sent to the countryside, and placed all the blame for the misfortune of her marriage on Yu Bing. As Yu Bing wanted to stay away from the Yu family, she took the initiative to sign up and went to the countryside. She completely cut off contact with the Yu family and vowed to change her destiny!

“Aurora White, from now on, you’re not my fiancée anymore and you’re banished from the kingdom!”Taking out the fan to cover her mocking smile, Aurora watched the crown prince spouted the declaration from the stage on their graduation ceremony and sneered.Banished?So, the time has come?The corner of her lips curled up slightly.For her or for the kingdom?Because in Aurora’s eyes, she can only see a bright path for her future....Story set in settings similar to middle ages...
