Overlord: The Multiverse - Chapter 19: Three PKers.

What's it like to be wrongfully killed? Cheng Su felt she'd really hit rock bottom when she was yanked out of a building by someone who jumped. Talk about a true miscarriage of justice! But when she opened her eyes again, she found herself back in the eighties, replacing the 'culprit'? In her last life, she was clear and alone, but in this life, she had a promising, dazzling military husband, as well as a cocky and domineering third child? Ugh, spit on that! She had died with cheats, so since the husband was hers, she'd beat anyone who dared to snatch him—pummel one, annihilate two. She'd make gourmet food to sell at a stall, start a chain of restaurants, and earn the money herself. She'd have the children, flirt with her husband, and fight off any mistresses; as long as her military husband doted on her, all was good. With this cheat-code life, she wanted to eat well, drink well, gain both fame and fortune, and together with her husband, make a home anew! “This story is purely fictional.
