If you're not the protagonist, why don't you wait for death? At this moment, "Your European Emperor system has been bound to me:" If the protagonist doesn't have a system, then I'm invincible, but I may have a harem, and Sansan is the true love! ! But you can also bring a loli." If the introduction is too weak, please read the text. It is the first time for a novice author to write a book. This novel and its characters are purely fictitious.
