Nine thousand years ago, a catastrophic war between good and evil shattered the Spirit Realm. Mountains crumbled, rivers ran red, and countless souls perished in the chaos. The devastation echoed through the heavens, until even the Martial World (江湖, Jiānghú) learned of the destruction—news delivered by the mysterious Sun of God.
The Sun of God gave one warning:
> "Do not set foot in the Spirit Realm. For if the devils find a path into your world… Jiānghú will burn next."
But fate does not listen.
As the war reached its peak, one final battle decided everything. A lone hero rose—Liu Shengjie, a warrior of unmatched skill. With a single, treacherous blow, he struck down the mighty Mo Tianzun, the Demon Heavenly Lord—an act that ended the war and crowned him the savior of both realms.
What the world did not know…
Liu Shengjie had once been Mo Tianzun's most trusted right hand.
He betrayed his master.
He hid his past.
And he became a god in the eyes of men.
Celebrated across the Martial and Spirit Realms, Liu Shengjie took his place among the heavens as the War God. Peace reigned.
Until now.
Mo Tianzun has been reborn—as a young prince within the gentle Healer Cultivation Sect.
Unknown. Hidden. Growing stronger.
The world that once called him evil has forgotten.
But he has not forgotten the blade in his back.
Or the face of the man who plunged it there.
In a world of blades and betrayal, who is truly righteous?
And when the Demon Lord walks once more in mortal skin... will peace survive his rebirth? Or his rebirth will cause the Demon Lord's heart to be soft like he never felt before?
