Rebirth + strong woman
Shen Zhaoning wants to do only three things in his new life: break off the engagement, make money, and protect the Shen family.
Later, he married a sick man, Meng Yun, a concubine of the Meng family. He was so poor that he was so weak that even his servants could bully him.
Shen Zhaoning married him because he wanted to find a shield. Unexpectedly, this man pretended to be useless in the academy during the day, practiced swordplay in the yard at night, and hid the mandarin duck purse she sent under his pillow for five years...
(The title of the book is wrong. The male protagonist is a general, but the female protagonist is not.)
