In his past lifetime, he was an exceptional prodigy who practiced both medicine and martial arts. In this lifetime, on earth, he used his superb medical expertise and extreme martial arts achievements from his past lifetime to excel in the medical field and the ancient martial arts world. He moved his way towards the pinnacle!

Humanity was living peacefully on Earth for millions and millions of years until the day unknown monsters from beyond space invaded them.

When humans were about to disappear, some people with abilities came out to the light and shared their knowledge and powers with the world, and together, they managed to push back the invaders during a terrible war that had lasted for years.

This war had created many orphans, and among them, Kye had lost everything, even his parents. And the only thing he received from their death was a pale-looking necklace.

However, once the necklace finally activated, a system was given to him, and his life changed completely.

The system gave him quests to do, and Kye complied. He was getting stronger every time he achieved them, until the day it gave him a weird quest.
