After the Disabled God of War Became My Concubine novel volume 1 was written by Liu Gou Hua.

An outrageous thesis has just hit the desk of esteemed history professor Jiang Suizhou. Dubiously sourced, it tells the story of the General Huo Wujiu, a man who was captured, incapacitated, and forced to serve as concubine to his enemy's brother - the cut-sleeve prince who enjoyed men in his bed. For three grueling years, the general lived as a prisoner until he escaped and sought vengeance against his tormentors.

Convinced the story is pure fiction, Jiang Suizhou brands the thesis a failure, that is, until he wakes up as the cut-sleeve prince himself!

Now, stuck lording over his concubine and prisoner Huo Wujiu, Jiang Suizhou's only has one option to avoid facing the general's future wrath: Ally himself with Huo Wujiu. Still, this strategy could backfire if Huo Wujiu were to get the wrong idea about his intentions.
