Lin'an City during the Shaoding Period of the Southern Song Dynasty.
Jiang Yunshu is the daughter of a declining military general, and she has been engaged to Pei Wenyuan of the Pei family since she was a child. After Pei's father attached himself to the Zheng family, he felt that the Jiang family's family was of low origin, so he forcibly broke off the engagement on the grounds of "incompatibility". For a time, the whole city was in turmoil, and Jiang Yunshu became a laughing stock.
On the day she broke off her engagement, she prayed at Lingyin Temple and met a young man wearing a mysterious cloak. The man knelt down in front of the Buddha, his back silhouette lonely. When he turned around, Jiang Yunshu saw a cold and handsome face and a slightly lame right leg.
——It is none other than Gu Xingzhou, the legitimate son of Gu's family, the "lame god of war" who broke his leg in the battle of Caizhou three years ago and has refused to marry countless people since then.
The next day, the Gu family made a betrothal gift with ten miles of red makeup. The first betrothal gift was the iron certificate of alchemy written by Gu Xingzhou in exchange for his life.
On the wedding night, Gu Xingzhou lifted his hijab and said calmly: "I married you not as a gift, but because I recognized your strong character."
In the court, the Lord He faction forced him to hand over his military power on the grounds that he was "unfit for usefulness"; in the back house, noble ladies such as Zheng Minglan laughed at Jiang Yunshu for "marrying a cripple". The couple supported each other in the storm - he taught her to ride and shoot, and she researched medicine for him; he responded to the court's doubts with his illustrious military exploits, and she used her math talent to help the Lin family investigate the embezzlement case, and backhandedly brought down the Zheng family.
When Pei Wenyuan knelt down and begged to get back together, Jiang Yunshu rolled her sleeves and sneered: "What you discard like worn-out shoes is a treasure that no one else can ask for."
When the enemy troops were approaching and the court wanted to cede territory and seek peace, Gu Xingzhou stood on the court with a staff: "The backbone of the Song Dynasty has never been on the knees."
A very nice book!
