I Work as a Cleaner in the Underworld

[1vN harem with multiple male leads and a romantic rivalry + all male leads' first time + heroine grows strong later + powerful men bow their heads]

After Ye Feifei dies, she becomes an unregistered ghost in the Underworld and is forced to sign a "contract of servitude" to clean the Mirror of Karma.

On her first day at work, however, she gets bound to the [Yang Realm Return Conquest System]

Mission: Max out the affection of four lunatic male leads in the Underworld and she'll be revived and sent back!

Jiuming, judge of the Office of Rewarding Good Deeds and incarnation of the Great Emperor of Dongyue.

He's the true culprit behind her death. No one has ever survived his Hellfire Sword, yet he carries the gravely wounded her back to his bedchamber and orders coldly, "Use the best medicine. Save her."

Lu Shang, an information broker in the Ghost Market and the King of Hell's illegitimate son.

He pinches her chin and chuckles. "Little cleaner, your life is a bargaining chip I've got my eye on."

Xie Ci, an inspector from the Office of Investigation and the King of Hell's adopted son.

This boss vanishes as soon as work ends, yet makes an exception and steps in when she's in danger. "She's my subordinate. No outsider gets to touch her."

Wuji, a nine-headed lion war god with the character "Ming" carved into his collar and a vicious old scar. The silent, devoted hound takes a lethal dose of entropy poison for her, restrained affection surging in his golden eyes.

Wangyou, a big-sister type with black hair and red lips, serves her a bowl of soup and asks, "Little girl, do you want to remember, or forget?"

Ye Feifei works to pay off her debts while furiously complaining about her cold-blooded boss.

Later, the Underworld is shaken.

Before the Mirror of Karma, white light surges from Ye Feifei's fingertips, cleansing countless vengeful souls.

Jiuming's Hellfire Sword clears the way for her, Lu Shang's Entropy Bone Fan protects her, and Xie Ci's Law Ruler restores order for her.

The ghosts are horrified: Who is this cleaner?!

The powerful figures who once looked down on her bow their proud heads behind her.

"Feifei," Jiuming says hoarsely, wiping the blood from her cheek. "Would giving you the Underworld be enough to make up for taking your life?"
