Qin Xiao, a down-and-out doctor, has his soul transmigrate into the fictional Qing Kingdom and becomes the crown prince, regent of the dynasty.
The late emperor is gravely ill and could die at any moment. The Qing Kingdom's borders are repeatedly attacked, neighboring countries eye its territory hungrily, officials at court form factions, and Qin Xiao's elder and younger brothers have long coveted the throne, repeatedly making secret moves to seize it.
Barely awake, Qin Xiao is swept into the struggle for succession. He acts decisively to protect himself, only to discover that undercurrents are surging at court.
As crown prince regent, Qin Xiao must tread carefully.
The imperial capital is rife with danger, and everyone is waiting for Qin Xiao to make a single mistake. But he suddenly changes his ways and begins wielding ruthless methods on a grand scale.
He curbs powerful ministers, executes treacherous officials, establishes the imperial examinations, opens a canal, pacifies the south and campaigns in the north. He drives the mighty Northern Qi to wail for mercy and wipes the Sakura Kingdom off the map...
The name of the crown prince regent wins the people's hearts. The Qing crown prince's might shakes the four seas and nine provinces!
