Ye Jin, the magistrate of Shangyuan County in the Hongwu era of the Ming Dynasty, just wanted to clock out, barbeque and drink wine, but unexpectedly activated the [9-to-5] system and lived a more unrestrained life than modern people. Until a hot-tempered "Old Man Guo" kicked open the gate of the county government's backyard with his elegant son, Ye Jin's salty life came to an end. Faced with the old man's repeated questions about "leaving early", "overtime pay", and "making ice with saltpeter", Ye Jin hit hard with every sentence, leaving the other party speechless. He thought he just met two serious angry young men, but he didn't know that the old man in front of him was none other than Hongwu Emperor Zhu Yuanzhang who was visiting privately incognito! When Ye Jin's astonishing remarks about "powering the country with business and taxation" and "system management of people" collided with Zhu Yuanzhang's deep-rooted concept of "emphasis on agriculture and suppression of business", a fierce ideological confrontation about the way of governing the country was staged in the backyard of the county government. On the one hand, Zhu Yuanzhang was furious at Ye Jin's "rebellion", but on the other hand, he was deeply shocked by his talent. Should we regard him as a madman who shakes the foundation of the country, or a wizard who can turn the tide? See how Ye Jin, a small county magistrate who traveled through time, used modern thinking to "educate" Emperor Hongwu, setting off an earth-shaking reform storm in this golden age when the empire was just emerging!
