I Just Want to Be a Quiet Emperor

This novel is not contracted. December 2022: I got so absorbed in doing research that I found many things were different from what I had originally expected. I may post an outline and write a medium- or long-length story in the future. [I just want to be a quiet emperor. Is that too much to ask?] In the lulls between interstellar wars, Shao Dong died and came back to life in the most literal sense. When he woke up, he found himself lying in some bed with a talking ball beside him. Then the System notified him: The Jingkang Incident is eight years away! And you have already become Song Qinzong, the Crown Prince of the Eastern Palace. Shao Dong has to save himself! The male lead will become all kinds of unlucky people, including but not limited to Qinzong, Jingtai, and Guangxu, as well as some fictional characters. The male lead is the top! The male lead is the top!! He has a System and needs a cheat. Without one, this is an impossible hell mode where he is sure to die. There will also be a CP: the male lead and that guy who appears later, with the male lead on top. Also, I'll do my best to make the descriptions accurate. Theme: Stay grounded in reality and look to the future
