In the world of Manga and Manhwa with system

Note:Well this is a fanfiction which I am writing as I am bored waiting for my favorite novels and fanfiction.
English is not my first language so expect some grammatical mistakes.

My name is Lucus and I was reincarnated into my all time favorite manhwa Lookism and I was given a system by God .
And so I started my journey in this new world
