World Development System - Chapter 270

Mu Jingzhe transmigrates into a book filled with sweet, doting love to become the useless supporting character who serves as a foil to the female lead. She also becomes the stepmom of five kids to her recently deceased husband.

Due to an unexpected turn of events, Xia Fei consumed a Super Gene Optimization Fluid that bore no brand, expiry date, instructions or stated its place of origin.
Our story begins here…

Cross is a laborer and helper working in multiple construction sites and stores to pay his bills and food. The pay isn’t much, but he is content with his life. He has a job, a crappy rented apartment, and a girlfriend.

But it all shatters when the world changes one day. A strange phenomenon teleports everyone into a world of fantasy, magic, dangerous beasts, and mystifying creatures.

Everyone is given abilities, skills, and spells and can level up like in a game.

And that’s not all. They are transported in a medieval timeline where technology is nonexistent, and living is harsher than one might expect!

When Cross swipes his hand, a screen appears, and the first thing he read.
