Ying Yi traveled to the fictional historical Daqian Kingdom, which was similar to the Spring and Autumn and Warring States periods in history. The emperor of Daqian had just died, the country was in turmoil, the court was full of traitors, and powerful officials were running rampant. Ying Yi had just been transferred to possess the most useless 16-year-old tenth prince. After spending a day on his behalf to find out some things, he originally wanted to live his life as an idle prince or a rich man. However, after many princes died because of party interests, the ministers finally compromised and prepared to support Ying Yi, the most useless prince, as a puppet emperor. Ying Yi doesn't want to be the emperor. If he does well, he will be like a bully, but if he doesn't, he will be a doormat! I guess he is the latter. He might as well be the salted fish prince lying flat on his back. But now that the royal family is weak, he has no choice but to be the emperor. However, he has a characteristic. If he doesn't do it, he must do it well, and it is not his character to accept anger. He used scheming to divide the ministers in the court, used his strength to fight, and conspired to create a "crack" for his own survival in the court!
