The Legend of Luo Tong's Northern Campaign

A celestial boy and girl are banished to the mortal world for secretly altering a human’s destiny. One becomes Tulu, a princess of Beifan, while the other becomes Luo Tong, a young general of the Tang dynasty.

Their former celestial companions, Zuo Yunshan and Cuiping, are caught up in the affair as well. Zuo Yunshan becomes Tulu’s childhood friend, while Cuiping becomes her sister on the grasslands.

After returning from her studies in the celestial mountains, Tulu treats Zuo Yunshan’s feelings as if they were dust.
