Yuki's origin

Yuki was born to the ice dragon clan which was one of the top-ranked dragon clan just below the chaos dragon clan. In her clan, she was treated nicely as she was one of a kind genius her skills and ability to control and use ice was never seen before even the clan patriarch her father believes that with her the clan would be the strongest dragon clan and in the future, she's the strongest clan member. But God doesn't seem to agree as to the Chaos dragon clan with the lesser ones which work together with them attacked and massacre the Ice dragon clan member. Seeing as there's no escape her father gave her a transforming pill as she can't transform to human form yet and put a pendant on her which sealed her dragon presence. She was then teleported away to a lower plane

Rather than crying all day she being the smart girl she was making a promise that she would one day avenge her parents. She then traveled all across the world and enter hidden ruins to find relics. She then started challenging strong person sometimes she loses and sometimes she wins to deepen and sharpen her battle senses she even started to learn about seals, formation, poison, pill concoction, blacksmithing, and medical knowledge. After she reached the peak of the lower plan she ascended to a middle tier plane and started to improve immensely. This cycle repeats until she ascended to the top tier plane and secluded herself and achieved strength enough to decimate the chaos dragon clan and it's lesser clans. She mastered all her skill and ascended from a low tier plane to a top tier in just above a thousand years. Her genius is just godly as even the most renowned genius in their respective field took about thousands or even tens of thousands of year to master it.

The battle lasted a few months and then Yuki came out victorious albeit was exhausted beyond belief. She then collected her spoil of war and improve more eventually she reached the peak of strength surpassing that of a god in her world and defeated him and she could go out and challenge the fighter in the God tier plane. Where she found out that each god has a title except one who's supposedly the 'One True God'. So she trained and defeated all other gods and went on to challenge the one true god at first she loses and escaped to learn all other elements and came back to fight him and killed him.
