Chu Feng crossed the Jiuzhou Continent and inherited the Ancestor God Blood Pearl, cultivating until he became a Peak Martial Emperor. By chance, he saved an exquisitely beautiful woman with whom he fell in love and married. Unexpectedly, the woman turned out to be the Empress of the Jiuzhou Empire, and after giving birth to twins, a dragon and phoenix, she left without saying goodbye. Through numerous rigorous cleansing and marrow-washing sessions conducted by Chu Feng, these young children astonishingly developed supreme Divine Runes within them, capable of suppressing all forms of energy across Jiuzhou. Three years later, while dull and adorable, the invincible but unaware siblings, took advantage of Chu Feng’s secluded meditation during Crossing the Divine Tribulation, sneakily slipped out of the village, and embarked on a journey to find their mother.

No one here does their rightful jobs properly, be they heroes, demon kings, or creator gods… in fact, Bella felt as if they all had also started with the wrong faction!
