Xue Chengzu passed away, leaving his son Xue Yu with only a cabinet that could still handle government affairs (there were also some traitors), which made Xue Yu very angry. Since Xue Yu came to power, a nobleman named Luo Yu appeared out of nowhere and joined the cabinet according to his father's decree before his death. He spent his whole day dealing with government affairs and getting Xue Yu "back on track."
Intention: hard work
