Zhu Yi, a modern history PhD student, is harshly criticized by his advisor after defending the view during his thesis defense that Zhu Houzhao “was not a foolish ruler.” After getting drunk, he accidentally transmigrates to the eighteenth year of the Hongzhi reign (1505) and becomes Zhu Houzhao, the crown prince who is about to take the throne. He discovers that he not only has a modern understanding of history, but has also awakened a System.
