Xia Chunqiu, an ordinary girl who couldn't be more ordinary, was selected to participate in a ridiculous but life-or-death time-traveling game because of her ridiculous feature of "thin sense of existence". While traveling through time, due to a strange combination of circumstances, she saved the life of Zhang Guo's Imperial Preceptor Ye Jing. From then on, she had many light-hearted and funny stories with the people surrounding the Imperial Preceptor's Mansion in another world, and formed an indissoluble bond.
