I was pushed down the stairs at school and traveled back to the sixth year of Yuan Shuo. I met the general Huo Qubing and by chance (all kinds of difficulties) became their military advisor to help them fight against the Huns. Can the heroine save Huo Qubing, return home smoothly or change Xiao Huo's fate of immortality and rewrite history? Or talk about love with the infatuated and gentle Dr. Yan?
