Gb, abuse the male protagonist, double cleansing, 1v1 (The introduction is weak and I am not very good at writing) Xiao Mingshu, the eldest princess of Dayao, wields power in both the government and the public. The two countries were at war, and she designed to personally capture the enemy's famous young general Xie Heng. The iron-blooded general who used to be invincible on the battlefield was once reduced to a prisoner and imprisoned in the palace of the eldest princess. Xiao Mingshu held the man in the palm of his hand, humiliating him wantonly, pressing forward step by step, refusing to give him a chance to escape. The hatred of family and country lies between the two. He hates her for being domineering, but he cannot escape the prison she has set. Xiao Mingshu used power as bait and coerced her step by step to make this proud enemy general willingly surrender to her. Should he stick to the righteousness of his family and country and would rather die than surrender, or should he sink into the eldest princess's hot and paranoid nature and become her pet in the palm of her hand with nowhere to escape?
