Invaded by Otherworldly Species, I Awaken an SSS-Rank Talent from the Start

[There are completed novels in my profile. Feel free to check them out if you're interested!] University student Yu Xi receives a letter. It says that the world they live in is actually an 18+ angsty romance novel, and she's the heroine. In the near future, four male leads will torment her body and heart. But that's not the point. The point is that in a few hours, Blue Star will be invaded by an alien race, and the entire world will turn into a game. Half believing the letter, Yu Xi finds herself a handy weapon. The moment the aliens land, she charges at them with it. Reader's guide: 1. Game invasion; the entire world turns into a game. 2. The heroine is powerful, with a huge golden finger and a mountain of author-created settings. 3. A leveling story with a powerful female lead and little romance. 4. You can criticize the characters, but don't criticize me. I'll fight back. I'd also like to recommend a friend's novel: Modern-day sweet romance, [Secretly Married to My White Moonlight in Showbiz], by Jun Zhi. Theme: Hold on to hope and never give up.
