In the 21st century, Chen Fan, a scumbag student in the Department of History and a deliveryman, fell into the sewer while delivering orders on a rainy day, and was reborn as Zhu Houcong (15 years old at the time), the Jiajing Emperor who had just succeeded to the throne in the 16th year of Zhengde in the Ming Dynasty. With modern people's complaining soul, the sequelae of the takeaway system and half-baked historical knowledge, he embarked on the "irregular" imperial path in the strict hierarchy of the Ming Dynasty. While using outrageous operations to resolve the crisis, he also relied on forward thinking to enliven the dynasty, and finally grew from a "funny and cute new emperor" to "the Ming Dynasty's top emperor for eternity".
