Rise of Wolfthorn Empire

Wolf Thorn is a weapon, but it is also a codename and his name. He has four names, each representing a different experience and identity. His last name in this life was Ying Lai. After his death, he was given the posthumous title Qin Wengong and was buried on the top of Lishan Mountain. Since then, Qin has grown from a small border country to a powerful country ranked among the princes. Five hundred years later, his descendant Ying Zheng swept the six countries and unified China and became the first emperor in history. The Qin Empire also forged an indomitable iron-blooded spirit starting from Duke Wen. However, he is not a bloodline of the Ying family, so who is he?
