Reincarnated Author with a System

I am an author. I wrote many books in my life. But my first web novel - "Reincarnated Master with a System" became popular among readers. The most surprising thing is - I transmigrated into this novel. I don't know even who I am. I received a system after I rescued a girl. Surprisingly the system's name was "The Best Author System". I was happy but it didn't last long. Because I need to get stronger in order to finish "Death Quest" which was given to me without my consent.
