Su Mu

Background
“Su Mu is considered an outstanding hero. He led tens of thousands of armored cavalry and dominated the battlefields, sweeping up victories wherever they went. Unfortunately, he was remembered too foolish. In the end, his outcome was akin to casting the bows aside once the birds are gone and slaying the lackeys after they have outlived their usefulness.(FALSE)

He is known  Lord Wuding of the Country of Yan.
