Jiang Hu Zai Jian

Shao Mengzhu, the "brainless" young leader of the League, was trying to convince the "unhappy" demon lord Si Kongnan to reform and repent his sins. But not only did he fail to convince the enemy to surrender, he was captured and forced to become the demon lord's queen (huh)? An epic tale of tragic brotherly love that will truly bring the reader to tears...
