I Am Invincible in All Worlds

Get a system at the beginning and start spreading across the world I've been thinking about whether this book will come to Harem for a long time, but isn't it that we read fan fiction just to make up for the tragedy? Many of them read the entire novel just because they liked one of the characters. There will definitely be a lot of changes to the original rules. If so, please don't criticize me. I am a newbie and because of my family situation, I made some mistakes and planned to reopen. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
