Chu Mu Yun relied on his story of 《Demon Realm》 to become a one-hit wonder in JJWXC, but the him who had written seven mental cases to abuse seven mental cases to death would never have expected that he himself would transmigrate into this shitty novel!
What the hell is this system on the bracelet?
And what the hell is this either propose to seven men, or suffer the taste of a tragic death experience under the hands of these seven people?
I just wanted to write a novel to satisfy my bad interests, who would actually want to get tangled up with a bunch of mad dog sad*st crazies?

- Description from Novelupdates

Magic is the programming language of the world. But in a fantasy world, nobody has ever heard about programming. That is, nobody except Aurea. Formerly known as Aurora, she was reborn with all the knowledge she brought from Earth.She spent the 40 years of her previous life studying society, science, programming, hermetism, mythology, and alchemy. She died financially broke and emotionally broken, but all her accumulated knowledge and her nerdiness are about to pay off.She starts her life as the daughter of a slave, set against impossible odds from the beginning. But if incantations work as a programming language, then she knows exactly what to do to turn the tables. Words and syntax were the bread and butter of her former life, and material components look more like APIs and plugins.She didn’t meet a Goddess, wasn’t summoned like a hero, didn’t have a System giving her an ability. Instead, she was just dropped there to fend for herself. But with her knowledge, she doesn’t need a cheat skill. She is the cheat herself.
