Liu Chengxuan, a history student from the 21st century, somehow finds himself back in the Tang dynasty. He opens his eyes after a nap and wonders what happened. His father went away on business and died unexpectedly, leaving only his helpless mother by his side. No matter: since he is here, he might as well make the best of it.
But Liu Chengxuan never imagined that the vast history of the Tang dynasty would bear traces of his own life. Looking at the charming, mischievous young woman before him, his thoughts descend into chaos. Who can tell him what would happen if he married the granddaughter of Left General Li Guangzhou?
Living in the prosperous Tang dynasty, Liu Chengxuan rises from the impoverished son of a merchant to become an indispensable figure at court. He enters government service and benefits the people. Amid the chaos of a troubled age, he endures humiliation and hardship, turns the tide, and purges traitors from the court, eventually becoming an imperial tutor of his era.
