The Demon Realm seeks to unite the world and launches a great war against the Divine Realm.
Every plant and tree in the Divine Realm rises up in resistance. During the chaos, Tao Ying, the Peach Blossom Immortal, has her divine soul shattered.
To protect her soul, Mo Youchen, the second young master of the Demon Realm, descends to the underworld to argue with the King of Hell, then uses the blood from his own heart to preserve her spirit.
Whether she is reborn into the Dragon Clan or as a mortal, he keeps carving out blood from his heart to protect the scattered fragments of her divine soul.
To ensure he can provide this heart’s blood without pause, he goes on a killing spree, replenishing his strength by drinking the fresh blood of mortals. In the eyes of the world, he is the Demon King.
On their wedding night, Tao Ying pulls out a dagger and plunges it into his heart, claiming she means to destroy the demon. The splattered blood from his heart restores her memories of her past and present lives...
