Infinity: Female Angel of the Evil God

My name is Long. I got an unknown object one day, so I was killed and found out what it was. It turned out to be an unexpected opportunity. If there is an afterlife, I want to open the Crystal Palace to fill the entire infinite world. I would rather be a heinous villain and kill everyone than be a good person! I first got a system, but after I successfully recognized the owner, I found out that she was a female angel, and the system was only his ability. Do you know how many difficulties and obstacles there are, how many girls there are? This novel and its characters are purely fictitious.
