Wu Di's Journey to Another World

My name is Wu Di, I have no parents, only an adopted grandfather, and the grandfather also passed away not long ago, and now I live alone. Suddenly one day, I was sent to the Goddess Realm by some god, and the goddess from the Goddess Realm sent me to another world. The process was simple and crude, and they didn't care about the feelings of a little human being like me. Fortunately, I awakened to a cheat system that only I knew, called the lottery system. Since it was activated for the first time, the system gave me a lottery opportunity, and then I won "invincible", and then the system crashed. So, I had no choice but to continue traveling in another world... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
