I Married 4 Demon Kings!

Luo Li owes four husbands an apology she never gave. She wakes up in another world as the youngest disciple of a sect, the one everyone despises, with no money and no talent for cultivation, and the four men bound to her by soul contract already hate her for what the previous occupant of the body did to them. The previous Luo Li had also just been poisoned by a man she had been fawning over. The Luo Li who arrives worked office hours until she died of it, and she does not intend to lose. A system pays her back ten times whatever she spends on the four men. She starts over with them one at a time: the domineering demon lord, the proud demon emperor, the cold swordsman who says little, and the scheming ghost king. She goes from the sect's useless disciple to its awakened holy maiden and rewrites what the world thought was settled. When she cannot decide which of them to call on for the night she suggests all four at once, and there is a fifth man at the door waiting his turn.
