The MMORPG ’EVR’ was released unexpectedly one day, along with its advanced equipment that allowed players to fully immerse themselves in the game, even though prior VR technology wasn’t nearly as realistic. To prevent people from replacing their real lives with the game, the servers were shut down during the day and on weekends. I was the best at the game, but since I had no friends or family, I could only watch and bet on sports while waiting for the servers to reopen—until the day I died and regressed to a week before the game was released. I know everything that will happen in the game. I know the game is not just realistic; it’s real. And for some reason, I don’t need to log out!

The NPC sets out on a journey to defeat the Demon Lord, joined by beautiful girls he meets along the way.---This is an NSFW story, so if you're under 18, turn back now, son. No NTR, and no full-on Yuri. There might be slight Yuri—like girls kissing and stuff during threesomes—but it's not that kind of Yuri where the girls fall in love with each other while in a relationship with the MC.---

“I think… my boyfriend is trying to kill me,” Lin Sanjiu muttered.

As she thought about that rich, handsome, and gentle boyfriend of hers, she could not help but tremble all over.

At the present, someone close to her had personally raised the curtains to an apocalyptic hell, and slowly, it was creeping up to her.

What if earth devolved into a apocalyptic hellhole? What if you found out you not only have to survive just one apocalyptic event but have to struggle through multiple worlds with different end-world scenarios? And you get to meet more superpowered crazies than you can imagine!

Presenting the worst nightmare that your weird doomsday prepper neighbour with a bunker full of canned beans could have, Doomsday Wonderland is a novel filled with subverted tropes, non-OP characters and a female friendly label which offends all politically correct fanatics.

As ‘lucky’ humans evolved to posthumans with abilities to adapt to the New World or mutate into disgusting duoluozhongs to survive, follow Lin Sanjiu as she struggle through the multiple challenges to just live one more day… and make sense of this New World that will no longer be the same.
