Yang Mu wakes up and somehow finds himself emperor of a small country.
His civil and military officials are waiting in the grand hall, along with a newlywed empress waiting to consummate their marriage.

Could he really have become the ruler of a doomed kingdom the moment he woke up?

In short, this is a story about how knowledge changes one's fate...
