Playing Lucky Dice in Infinite Flow Instances

【Instance-Based Game + Frail but Beautiful Female Lead, Not a Strong Female Lead but Not Foolish and Has Her Moments + One-to-One, Both Leads Inexperienced + Age Gap】 “Welcome to the large-scale instance escape game, player Song Yishu.” After years of struggling with a blood disorder, Song Yishu is suddenly and unwillingly chosen to take part in an infinite-flow instance game. Completely unsuited to physical exertion, she has no choice but to start clinging to powerful allies if she wants to survive. When your life is at stake, who cares about saving face! PS: The female lead is 19, and the male lead is 26. Both leads are players. The male lead appears in the second instance and falls in love at first sight. The female lead is good at putting on an act. To her, staying alive and completing her mission are what matter most. She isn't a bleeding heart, but she has basic morals. Because of her own experiences, she is rather detached when it comes to love. Falling in love for no particular reason, and my kink for pretty men and women. I'm terrible at naming things. No one besides the main characters has a name in the story, only codenames. I picked the book title at random too. 【Content warnings: First-time writer, prose not guaranteed, irregular updates though I'll try my best, not many horror elements despite being infinite flow, mostly game-style instances】
