After discovering this point,
the attention of the old Emperor truly fell on Chen Mu.
He tentatively began to increase Chen Mu's responsibilities, appointing him to the Ministry of War right after his coming-of-age ceremony.
The outcome was that, when Chen Mu was a leisure Prince, he completely remained a leisure Prince. Once he took up a post at the Ministry of War, however, all the tasks entrusted to Chen Mu were handled impeccably. Every affair at the Ministry of War was managed in an orderly manner, with no fault to be found.
The old Emperor quickly transferred Chen Mu to the Ministry of Revenue, and again, during Chen Mu's tenure there, there were no errors or omissions. Within a few short months, he managed his responsibilities in an orderly fashion.
Eventually.
Another year passed, and the old Emperor's life was nearing its end.
