My Whole Family Died for the Country and Became Stupid. After I Woke Up, I Had All the Power in the Government!

In the battle at Yinshan, all the men of the Xiao family were wiped out, leaving only Xiao Yunqing alone. He was bullied by his vicious parents-in-law and his wife was unreasonable and humiliating. Once he woke up, he held the iron book of elixir and swore an oath to the world to revive the prestige of the Xiao family and control the country's mountains and rivers. Anyone who kills my parents and brothers will be punished! Anyone who insults me like a pig or a dog will be slaughtered! Anyone who violates our country, rivers and mountains will be destroyed! I am the Duke of Daqian Town, the sixth son of the Xiao family, Xiao Yunqing!
