In the Second Generation of the Trench, He Changed To the Ruanfan Script - Chapter 49:

Lived for the sword, died for the sword.

The world has changed into something like a game.

It resembles a survival virtual reality game where people were attacked by zombies and monsters.

And I was the last user of that game.

This book is about baby-making.

Xiao Rou, a girl growing up in a poor countryside family, finds that she’s actually the daughter of a wealthy couple. Her mother had mistaken another girl for her back at the hospital. Thinking she would change from an ugly duckling to a noble swan and live happily ever after with her real family, reality strikes her in the face.
