Daliang and Northern Xinjiang have been fighting for years, and the people are miserable. Shen Zhaoning, the most noble Princess He Ning of Daliang, has practiced martial arts and studied since she was a child. She is smart and courageous, but she cannot escape the fate of being sent to the grassland for marriage. She originally thought that what awaited her was humiliation and prison, but she didn't know that the prairie king Erhe was not as cruel and cruel as the rumors said. He is the bravest eagle on the grassland and a puppet who has been ignored in the political whirlpool. Two people caught up in fate collided in a seemingly humiliating marriage. Shen Zhaoning was unwilling to be reduced to a chess piece, and relied on his resourcefulness and courage step by step. In the end, he turned against the guest and won dignity and love for himself. This is a woman's transformation from a chess piece to a chess player, a legend from humiliation to control, from resentment to mutual understanding, from being forced to actively embracing.
