Baek Jung-hyuk — once known as one of the three greatest divine doctors in the Central Plains.
He dreamed of achieving greatness as a healer, and together with the Tang Clan, he worked to create a groundbreaking technique that had never existed before.
After years of hard work, just as their ultimate art was about to be completed, the Tang Clan betrayed him — and he met a tragic end.
“Do you seek revenge? Then I shall give you power.”
After his death, on the border between life and death, Baek Jung-hyuk met the Heavenly Demon — the strongest being in history — and learned the Heavenly Demon Divine Art from him.
“Save the world that’s falling into chaos.”
Granted power strong enough for revenge, Baek Jung-hyuk made a deal with the Heavenly Demon — in return for saving the world, he would be allowed to live again.
Reborn as Baek Mu-heun, the notorious fourth young master of the Cheonmu Clan, he now walks a new path.
Can Baek Jung-hyuk truly avenge his death… and still save the world?
