Invincible Origin Emperor System

This book is an invincible dual-system text with a harem in which the protagonist is devoted to love. At the beginning, he became an emperor in the flesh. If he refused, he would be slapped to death. After all, I've been through so much harm, why don't you hit me if you don't accept it? I originally thought I was invincible, but I found out later. The realm of Heavenly Emperor is just a new beginning. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
