Song Renzou was an ordinary modern man who unexpectedly traveled through time to the Ming Dynasty after an accident. Shortly after arriving, he found a ragged little boy by the roadside. After questioning him, he was shocked to discover that the child was Zhu Xiongying, the legitimate eldest grandson of Zhu Yuanzhang. Unable to bear abandoning the child, Song Renzou and the honest, simple-minded Daizi took him in. The three became dependent on one another, fleeing hardship from their hometown and enduring a rough journey before eventually reaching the capital. Little did they know that, just as they entered the city gates, they would run straight into Lan Yu, the powerful general who dominated the imperial court. Lan Yu immediately recognized Zhu Xiongying, and the three were instantly swept into the whirlpool of the Ming Dynasty's struggle for imperial power. From that moment on, their fates were no longer in their own hands.
