City War Ghost System

This is my first time writing a novel. I have read a lot and thought a lot, so I just want to try writing one myself. I can write it how I want to write it, and if it doesn't work well, I can do it as I please. The male protagonist's rebellious period allows him to accidentally get a war ghost system. With the help of the system, he makes war full of art and helps the protagonist become stronger and stronger. There is no love or hatred, only war as he wants. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
