After returning from her tribulation in the mortal realm, Lian Manman thought she'd go back to the Immortal Realm and become a humble lotus fairy. Instead, she arrives in the Demon Realm and is mistaken for Xingye, the Demon Lord who fell ten thousand years ago.
But the Life Lamp has gone out, and the Dark Jade Ring has acknowledged her as its master. She has no choice but to take up the mantle of Demon Lord.
Her subordinates Feng Jiu and Long Xiao: Welcome back, Demon Lord!
Demon Venerable Qian Mo: Big brother, you're back. Though should I call you big sister now?
Demon Lord Lin Yi: I've waited ten thousand years for you, and you've become like this? Are you really Xingye?
Demon Lord Cang Qing: I don't care if you are him or not. I'm the third brother, so you can only be the fourth.
Asura King Jun Hao: Who cares? You're back, and that's what matters. I won't let you die again!
Feng Jiu: My lord, how about we do some cultivation?
Cang Qing: Come on, let's fight and see who gets to be the third brother.
As she gradually adjusts to her new identity, Lian Manman changes her name to Lian Man and begins a second life as the Demon Lord.
But the real Xingye has a fragment of his divine soul resting in Lian Manman's sea of consciousness. As the truth from ten thousand years ago comes to light, Lian Manman finally learns why she came here…
