After My Mother Remarried, I Became My Grandfather's Golden Child

After his mother remarried, his younger brother found out from his father's relic box that his grandfather's family came from a military and political family. He wanted to be the prince of Beijing, so he chose his grandfather first. But his grandfather only asked him to farm and herd sheep, write and engrave seals, and study hard. He never had the chance to appear in public. On the contrary, I stayed in the Jiang family and grew up with my stepfather. I became his right-hand man and became a member of the upper class. He went crazy and killed me, and he and I were reborn to the point where we had to choose between grandpa and mother.
