Son-In-Law of the Northern Xinjiang Emperor

The feared dragon-killing general Xiang Long is actually the son-in-law of the Xu family on the border? ! On the battlefield, he was like a god of death, crushing millions of aliens! But in the Xu Mansion, he became the idiot son-in-law whom everyone looked down upon, and was despised by thousands of people! For the sake of the Daqiong Empire and his beloved woman, he endured humiliation and carried out a sword to kill enemies all over the world! Cruel Huns, treacherous villains, dandy children... Who dares to offend me, Xiang Long! I'll beat the shit out of you! !
