Delta Force: My Yandere Girlfriend, Mai Xiaowen

(Yandere + Rule Challenges + Twin Setup + Apocalypse Survival + Changing Stats) You unexpectedly find yourself in the world of Delta Force, only to discover that the apocalyptic crisis here is even more terrifying than the zombies themselves. The state of the apocalypse: The soldiers of Asara have turned into zombies, while the Hafk forces have evolved into something even more difficult to deal with. They know how to ambush and flank, and can even modify weapons. Only the Heart of Africa can resolve all these difficulties. The twins, Mai Xiaowen: In the real world, she is an exceptionally skilled fighter who builds you a safe shelter. But the basement is covered in all kinds of survival rules. You have to praise her three times a day, or you'll be stuck practicing gun disassembly until the early hours. If you hear crying at 3 a.m., it's only an illusion. Whatever you do, don't open the door. Her reflection, who calls herself Luna, warns you that Mai Xiaowen may be dangerous, yet secretly gives you a Hafk insignia... Later, she breaks free during a mission. Not only does she escape, she also takes along a terrifying monster capable of destroying half a base, and orders it to hunt down everyone who knows the secret of the Heart of Africa. Survival tips: 1. Survive Mai Xiaowen's training. Answer a question incorrectly and you'll get a “little punishment.” 2. Never let her special stat reach its maximum, or the consequences will be terrifying. 3. Under no circumstances let anyone know that you just arrived in this world and are still a novice who doesn't know much!
