The Idle Prince of the Hongwu Era

In the seventh year of Hongwu, Zhu Zhen was ten years old. He had died once, then lived again. In his previous life, he was the Prince of Chu of the Ming dynasty, and died in the final years of Yongle. His soul traveled six hundred years into the future, where he studied hard and earned a doctorate in engineering. When he opened his eyes again, he was back in the Hongwu palace. He remembers that some people will die, and that some things should never happen. But he can't remember when or why. This time, he's still a child, unable to do anything. But he doesn't want to stand by and watch again. So he pretends to be an idle prince who neglects his studies. He doesn't fight for power, form factions, or concern himself with important affairs. He simply sets things right, one by one, before they can go wrong.
