Da Qian's Stupid Son-In-Law: from a Soldier in the Border Army to an Emperor of All Ages

At the beginning, I was treated as a "reward" for military achievements, and I was forcibly married into a declining family. The whole city laughed at me for being a stupid son-in-law who couldn't even read! But they don't know that on the surface I am submissive, but secretly I have activated the [Strongest Domain System]! While they were still mocking me for only knowing how to farm, my water-powered forging hammer had already armed me with three thousand heavy-armored Mo Dao Guards! When they laughed at me for clinging to the powerful, my invincible fleet had already blocked the rivers and seas! When I travel all over Jiuzhou, I wonder, father-in-law, will your knees still be strong? In the last years of the Qian Dynasty, vassal towns were separated, foreign tribes were knocking on the gates, and people died of hunger everywhere. In this troubled world, people's lives were worse than dogs! Who would have thought that the one who ended it all would be a frontier army scout who crawled out from among the dead, an unknown person who was forced into marriage! Based on the border land, he built an invincible army and used thunderous methods to create a bright world where everyone has food to eat and clothing to wear! The emperor takes turns, come to my house this year! Watch the rise of the son-in-law, clear the emperor's side, bring peace to the world, reorganize the country, and reach the top of the Ninth Five-Year Plan!
