Delta Force: My Yandere Girlfriend, Mai Xiaowen

(Yandere + rule-based challenges + twin setup + apocalypse survival + changing stats)

You unexpectedly enter the world of Delta Force, only to discover that the apocalyptic threat here is far more terrifying than the zombies themselves.

The state of the apocalypse:

The soldiers of Ahsarah have turned into zombies, while the Hafk forces have evolved into something even more difficult to deal with. They know how to lay ambushes and encircle their enemies, and can even modify weapons.

Only the Heart of Africa can solve all these problems.

The twin Xiao Wen Mai:

In the real world, she's an exceptionally strong fighter who builds you a safe home. 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 Xiao Wen Mai may be dangerous, yet secretly gives you a Hafk badge... Later, she breaks free during an operation. Not only does she escape, she 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.

Your survival tips:

1. Survive Xiao Wen Mai's training. Answer a question wrong, 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 find out that you've only just arrived in this world and are still a newbie!
