Fantasy

My name is Li Wei. After my parents passed away and left me with a huge debt, I was adopted by a distant uncle in the United States of America and went to New York to live with him.
    Wait, what the hell is this Middle Ages Adventure System? It identifies my uncle as a mad Knight? The wealthy district of the Upper East Side is a Noble Courtyard? It looks like there's a succubus den up ahead, I've decided to go and explore it...
    First day in New York, I abided by the law.
    Second day in New York, I tested the waters cautiously.
    Third day in New York, I decided I would protect the world.
    Fourth day in New York, I started to get tired of it. This world sucks.
    Fifth day in New York, am I the only Superman in this world?
