My name is Gu Ning, and I am the only eldest son with a different surname in the Dafeng Dynasty. I have a lying-down sign-in system, and I can get various rewards every day without doing anything. Now I am on the verge of becoming a land god. But when I woke up, I found that I had become Emperor Dafeng? The emperor is still a bitch? ! Fortunately, the system also followed... No! Doesn't this mean signing in for her? … My name is Zhao Ji, I am the emperor of Dafeng, but now I have become the most dandy in the world. Etc? How could he have such cultivation? ! What the hell are three hundred thousand Snow Dragon Riders? ! And why do I seem to become stronger after switching back every seven days? ! I originally wanted to be a wise king who would cut down the feudal vassal and expand the territory, but Gu Ning is really terrible! Forget it, let him do whatever he wants...
