My Dead White Moonlight Has Suddenly Started Attacking Me

[The Demon Lord thought he was invulnerable, but his dead white moonlight suddenly began attacking him.]

Cui Lingyue died, and there was nothing left in the world for the Demon Lord Yinghuo to care about.

His demonic cultivation reached its peak, and he severed all emotion and love.

The only thing he remembered was that he had to take revenge, killing everyone who sought a replacement after Cui Lingyue died, because that was an insult to her.

After coming back from the dead, Cui Lingyue somehow became her own substitute.

But she realized that this world seemed a little different from what she'd imagined.

Never mind her family and friends, but why were even reclusive experts she'd never met, sworn enemies who couldn't stand one another, and even a rumored love rival telling stories about how their beloved had died, reminiscing in front of her gravestone?

It was as if she'd been involved with all of them. Don't ruin her spotless reputation just because she's dead, okay?

And her junior brother: you went undercover in the Demon Realm on orders, but you became the Demon Lord this quickly? Are you sure you're working toward the right goal?

Notes:

1. A universally adored Mary Sue heroine who is everyone's white moonlight, including a girl who has a crush on her.

2. I've decided: you're the male lead, Demon Lord!

Theme: Never give up hope
