The Max-Level Killer Starts from Scratch

[Female protagonist + divine games + no male lead] (Tomatoes tags things at random, so the tags aren't very accurate.) Shen Xi is an assassin, with a graduate degree from a prestigious university as her side profession. One day, while taking aim at a target, everything suddenly goes black. When she opens her eyes again, she finds herself in an unfamiliar, sealed room. The walls are covered in blood, and it's all hers. Have her enemies kidnapped and imprisoned her for revenge? Since they failed to kill her, she'll just have to kill them instead. But... after escaping, Shen Xi looks up at the blood-red sky. ??? Where is this? What? You're telling me all three of my houses and my hundred million in savings are gone? I'm bankrupt? Shen Xi, down on her luck, looks at a game that offers a reward of two hundred and resolutely clicks “Start Game.” A few things I'd like to say: All kinds of people might appear in this story. The values of every character, including the protagonist, don't necessarily reflect my own. The female lead isn't exactly a bad person, though some of her actions early on may seem heartless. She's somewhat emotionally detached. I don't have a detailed outline, just a general idea of where the plot is going, so I can't make any promises ₍˄·͈༝·͈˄*₎◞ ̑̑ There are lots of different kinds of games. I'll try to make things logical, but if I can't keep track of it all, there's not much I can do ╭(°A°`)╮
