Traveling through the Tang Dynasty: From the Duke's Bastard to the Sword of the Khan
Advanced military industry dimensionality reduction strikes, commercial monopoly wealth that rivals the enemy, battlefield gods crushing powerful enemies, emperors and empresses lovingly favoring only one person, systematic power rewriting history
Era background: In the first year of Zhenguan of the Tang Dynasty (627), the Xuanwu Gate Revolution had just ended, and Li Shimin ascended the throne for the first time. The humiliation of the Weishui Alliance was still there, with the constraints of aristocratic families inside and the surrounding barbarians outside.
Qin Feng (also known as Chang Geng), was a doctor of military industry and a business operator before time travel. After time travel, he became the eldest son of Qin Yue, Duke Huaide, an unprecedented duke with a different surname in history. The original subject was weak and cowardly. Due to the incompetence of his mother's family, he was suppressed by his aunt and brother. He fell into a well and changed his soul.
