The Cannon-Fodder Eldest Brother in the Story of the Rebirth of a Legitimate Daughter

Transformed into a cannon fodder and a bastard who read a novel about the revenge of his legitimate daughter, Jian Xungui just wanted to protect his aunt and sister within his ability so that they would no longer go astray. Unexpectedly, he was exposed on the first day he wore it and was taken to the front yard. He was not allowed to have contact with the outside for four years. His aunt had long since settled the feud with his sister-in-law, and he became the real eldest son of the Duke of Zhenguo. His father was ambitious, so he took out the colored glaze and gunpowder prescriptions to help his father plot to usurp the throne, but he didn't want to be on this road. He met many friends and lost many.
