The Long-Lantern Battle Signal

What is there to be afraid of? If the sky falls, I'll hold it up!

Min Yu-su, the daughter of the Mu'guk Gong family, loses her life in a war against the Liao and regresses six years into the past, back to the foolish days when she tied herself up tightly and ate only bird-sized portions of food, all because she wanted to become the Crown Princess.

Carrying the divine power inherited from the Min family of the Mu'guk Gong household from her father, she already knows the unhappy future awaiting the Mu'guk Gong family. So she gives up pretending to be a refined lady any longer and begins learning martial arts from her warrior father.

Meanwhile, Kang Yeon-ji, the Third Prince living next door, possesses an extraordinary ability to see ghosts. Because of that, he nearly discovers Min Yu-su's secret of regression, but she fools him by passing off her previous-life self as a guardian spirit.

After that, for some reason, the two become entangled in all kinds of incidents unfolding in Kaifeng City...

The woman with monstrous strength, Min Yu-su, and the man who can see ghosts, Kang Yeon-ji.

What future awaits these two troublemakers, Kaifeng City's biggest headache?
