Tensei Kenja no Isekai Raifu ~Daini no Shokugyo wo Ete, Sekai Saikyou ni Narimashita~ - Chapter 2 - I Used Magic

Noah Carter wasn't special. A broke programmer working from his cluttered studio apartment, he spent his days applying for jobs, getting rejected, and scraping by with low-paying freelance gigs.One ordinary Tuesday, while debugging code at 3 AM surrounded by energy drink cans and ramen cups, Noah accidentally broke reality.He didn't mean to... it just sort of... happened.A system message appeared, floating in his vision. The Idle Tycoon System had chosen him. His first shop: a small bakery in a Magical Medieval world where demons, dragons and half-humans exist.Every sale generated automatic income, day after day. Every new world unlocked new opportunities.Noah brought it all back to Earth, selling what he could, keeping what he couldn't. One shop became two. Two became a hundred. A network spanning dimensions, time periods, and realities—all generating income while he slept.Countless years later, Noah raised his head from his pillow and realized something unexpected. The broke programmer who couldn't land an interview had become the richest man in the universe!

She was the illegitimate daughter of a wealthy family—abandoned by her father, oppressed by his legal wife, and humiliated by the so-called sister. She watched her mother perish in a raging fire and was thrown into the flames herself.Her name was Janice. And she died in that fire.Ten years later, under a new identity and the name “Janet,” she survives in silence. Forced by her stepmother to marry a wealthy heir rumored to be “paralyzed and disabled,” she becomes entangled in a vicious struggle of family betrayal and ruthless power games.With cold eyes, she watches the hypocrites who once trampled her into the mud—one by one, they will become prey on her road to revenge.Her wheelchair-bound “husband” Philip, the feuding brothers Charles and August… But what she didn't expect was that the boy who once quietly handed her a handkerchief all those years ago would become the most unpredictable piece in her game of fate.She has returned—not for hatred, but to personally end the past that was once crushed beneath their feet.

With the revival of spiritual energy and the breakdown of the order of species, it is a difficult test whether human beings can still stand at the top of the biological chain.

(There is already an old book, The Strongest Descends in the City, you can read it.)

- Description from novelbuddy

One day, I woke up only find out that I’d become a Demon Lord, an individual responsible for protecting a dungeon. The world I’d been spirited away to was one filled with violence. Gigantic monsters wandered through it and competed with each other each and every day for the right to survive. I had no choice but to strengthen my dungeon’s defenses in hopes of living another day—or at least that was what I’d thought. For some odd reason, I instead ended up spending my days in relaxation and bliss.
