After Double Penetration, I Married Beishuo, the Disabled God of War

In ancient times, my best friend was the queen and I was the concubine. By chance, I married Fu Ciyuan, the God of War in Beishuo, who was disabled in both legs. The world laughs at his disability and makes me humble. Who knows—— He is the powerful one hidden behind a wheelchair, I am a strategist hiding in my identity as a concubine. The queen's best friend supports her, but her disabled husband only favors her. I'm not afraid of house fights, intrigues, or harems. In this life, let's see how the concubine and the disabled God of War work together to rule the world. Fu Ciyuan is the only god of war in Beishuo. He led his army across the border at the age of fifteen, winning every battle and never losing. Four years ago, there was a decisive battle between Beishuo and Dayong on the border. He was already sure of victory, but he was plotted against by his brother, the Prince of Beishuo. The prince secretly collaborated with the enemy, cut off reinforcements and exchanged food and grass. Fu Ciyuan was besieged by the enemy on a cliff. In order to cover the retreat of the 30,000 remnant soldiers under his command, he cut off his back in person, but his hamstring was cut off by the enemy general with a knife. He was also shot through his knee by random arrows and fell off the cliff. Although he was rescued by the soldiers desperately, the tendons of both legs were severed and the bones were shattered. He could never stand again in his life and could only be trapped in a retro carved wooden wheelchair.
