After Rebirth, I Sent the Evil Mother-In-Law into the Enemy Camp

On the bridal night before rebirth, my mother-in-law served me soup: "Is the son of a widow worthy of giving birth to a legitimate grandson?" I drank it with tears and suffered all the humiliation for ten years with nothing to do. Only when he was about to die did he realize that his mother-in-law had poisoned her husband to death in battle. When I opened my eyes again and returned to the wedding night, the bowl of soup was steaming. I grabbed my mother-in-law's wrist with my backhand and said, "This blessing should be reserved for your own son." Looking at her frightened eyes, I chuckled: "Guess, if he knew the cause of his brother's death, how would he honor you?"
