Exiled, I Secretly Raised an Army in My Fief and Became an Unparalleled Emperor

I transmigrated to Great Wei ten years ago. As a frail young marquis, I fought my way to victory after victory, expanding Great Wei’s borders, crushing the rebel forces, and holding back foreign tribes! But when I returned in triumph, Great Wei’s empress, Wei Hanyan, repaid me by turning against me. She made me Prince of Tingzhou. In truth, she gave me only two hundred personal guards and sent me to die on the desolate, rebellion-ridden frontier! If that dog of an emperor won’t act like a person, then I have no reason to be a loyal subject. I’ll build up my troops, forge weapons, and advance technology... When I return, it will be the end of Great Wei. I am the one true emperor of this realm!
